Description

Wireless burner socket

The present invention relates to a wireless burner socket, in particular to a wireless burner socket that can simplify the wiring configuration when used in a burn-in test.

The burn-in socket in the existing burn-in test is usually composed of a base for accommodating and testing a test object (e.g., IC, chip, etc.) and a heat-conducting structure (e.g., heat sink, temperature plate, etc.) disposed on the base and used to discharge the heat accumulated by the test object during the test, wherein wires are disposed between the base and the inside of the heat-conducting structure to electrically connect various electronic components in the burn-in socket. However, the wire connection will cause the wires to be messy. In order to overcome the problem of messy wires, the common technical means is to use a large number of heat shrink sleeves, tie bands, fixing clips, pressure strips and other wire management tools to organize the wires.

Nevertheless, this method of wiring has a negative impact on the service life of the burn-in socket and subsequent maintenance. Specifically, when the burn-in socket is operated by external force (for example, when the burn-in socket is opened and the test object is placed in it), due to the high rigidity of the wire management tools, the stress will be concentrated on the section of wire with lower rigidity, and the section of wire will need to bear the weight of the wire management tool. Therefore, after the burn-in socket is operated many times, the section of wire with lower rigidity will be excessively bent and deteriorated, eventually resulting in a disconnection, affecting the transmission of the test signal. More importantly, for subsequent repairs after disconnection, the repairman needs to remove the wire management tools to re-solder the wires. Therefore, using wires to connect various electronic components and using wire management tools to organize the wires is not conducive to the repair efficiency and time cost of the burn-in socket.

In addition, the wire connection method may require a wire connector (such as a pin header connector) to be configured on the base or thermal conductive structure, occupying limited space on the burn-in board.

In view of this, the inventor has developed a burner socket configuration that can simplify the wires and does not activate the wires during operation, so as to effectively improve the shortcomings of the previous technology. This is the design purpose of the present invention.

In view of the above, the present invention configures a corresponding male-female plug electronic connector on the burner socket and the burner motherboard to overcome the deficiencies of the known technical means.

To achieve the above-mentioned purpose, the present invention provides a wireless burner socket, comprising: a main body, arranged on a burner mainboard, and having a receiving space; a heat conducting part, movably connected to the upper part of the main body, and arranged to move the heat conducting part between an open position and a closed position relative to the main body according to an operation, the heat conducting part having: a contact part of a connector or one of a female socket, the contact part or the female socket being electrically connected to the heat conducting part; wherein the burner mainboard is provided with the other of the contact part of the connector or the female socket, and when the heat conducting part is in the closed position, the heat conducting part and the burner mainboard are electrically connected based on the contact part contacting the female socket.

The wireless burner socket as described above, wherein: the heat conducting portion and one of the contact portion of the connector or the female socket are electrically connected via a socket adapter plate; and the burner motherboard and the other of the contact portion of the connector or the female socket are electrically connected via a motherboard adapter plate.

In the wireless burner socket as described above, the socket adapter plate is disposed on the bottom side of the heat conducting portion, and the contact portion of the connector or one of the female sockets is disposed on the bottom side or side surface of the socket adapter plate and exposed to the heat conducting portion.

The present invention will be described more fully below with reference to the drawings, and specific exemplary embodiments are shown by way of example. However, the claimed subject matter may be embodied in many different forms, and thus the construction of the claimed subject matter covered or applied for is not limited to any exemplary embodiment disclosed in this specification; the exemplary embodiments are merely illustrative. Likewise, the present invention is intended to provide a reasonably broad scope for the claimed subject matter applied for or covered.

The term "in one embodiment" used in this specification does not necessarily refer to the same specific embodiment, and the term "in other (some/certain) embodiments" used in this specification does not necessarily refer to different specific embodiments. The purpose is, for example, that the claimed subject matter includes a combination of all or part of the exemplary specific embodiments.

First, the configuration of the wireless burn-in socket 1000 of the present invention is described. Please refer to the schematic diagram of the burn-in socket in the open position in FIG1. As shown in the figure, the burn-in socket 1000 has a body 1100 and a heat conducting portion 1200. The body 1100 is basically defined by a top side, a bottom side and four side sides, and a receiving space for placing at least one test object W is formed on the top side. The bottom surface of the body 1100 is configured with a plurality of detection probes (not shown in the figure). The detection probes form an electrical connection by contacting the bottom surface of the test object W, and then the test object W is subjected to a burn-in test. The burner socket 1000 is fixed to a burner mainboard 2000 or a printed circuit board (PCB) via the bottom surface of the body 1100. The burner socket 1000 is adjacent to a mainboard adapter board 2100 configured on the burner mainboard 2000. The heat conducting part 1200 of the burner socket 1000 is electrically connected to the burner mainboard 2000 via a connector described later (e.g., a spring-type connector or a spade connector).

The main body 1100 is provided with a heat conducting part 1200 on the upper side facing the top side, and the heat conducting part 1200 is pivoted on one side of the main body 1100 via a pivot 1300, and pivots along a circular arc rotation direction a1 and relative to the main body 1100 to define an open position and a closed position. The top side of the heat conducting part 1200 has a heat dissipation structure 1220 such as a heat dissipation fin assembly, a fan and/or a resistance thermometer. The bottom 1210 of the heat conducting part 1200 is provided with a heat conducting seat 1230 made of a metal heat conducting material, and the heat conducting seat 1230 and the heat dissipation structure 1220 are heat conduction coupled. The thermally conductive seat 1230 is used to appropriately press and contact the top surface of a test object W during the burn-in test (i.e., in the closed position) to discharge (or conduct) the accumulated heat of the test object W to the outside of the burn-in socket 1000, wherein the test object W can be an integrated circuit or other customized chip, etc.

Next, please refer to FIG. 1 and FIG. 2 simultaneously. The heat-conducting seat 1230 is disposed at the center of the bottom 1210 of the heat-conducting part 1200, and a plurality of heaters 1231 are disposed therein. The bottom 1210 of the heat-conducting part 1200 is further disposed with a socket adapter plate 1240, which is adjacent to the heat-conducting seat 1230, and as shown in FIG. 1, the bottom side of the socket adapter plate 1240 is disposed with a contact portion 1250 of a connector. The contact portion 1250 is electrically connected to the socket adapter plate 1240 by welding or coupling, and the contact portion 1250 is exposed outside the heat-conducting part 1200. In another embodiment, as shown in FIG. 2 , the contact portion 1250 is disposed on the side of the socket adapter plate 1240 by welding or coupling and is exposed to the heat conducting portion 1200. In addition, the heat conducting portion 1200 is embedded with a plurality of wires 1211, and the wires 1211 are used to connect a plurality of components disposed in the heat conducting portion 1200. The plurality of components are the heaters 1231 or the aforementioned fans and resistance thermometers. Specifically, a portion of the wires 1211 is electrically connected to the socket adapter plate 1240 by welding, and another portion of the wires 1211 extends between the heater 1231 and the socket adapter plate 1240. Therefore, by configuring in the above manner, the line length of the wires 1211 can be minimized to overcome the defects of the wire part in the prior art.

Please refer to FIG. 3, FIG. 4A and FIG. 4B. In this embodiment, a spring-type connector is used as the best embodiment. Specifically, a mainboard adapter board 2100 is disposed on the burner mainboard 2000. The top side of the mainboard adapter board 2100 is disposed with a female socket 2200 of a connector corresponding to the aforementioned contact portion 1250. The mainboard adapter board 2100 is configured to make the burner mainboard 2000 and the female socket 2200 form an electrical connection when in the closed position, wherein a plurality of conductive sheets are disposed at intervals on the surface of the female socket 2200. Similarly, a plurality of metal spring sheets 1251 are disposed at the positions of the contact portion 1250 corresponding to the conductive sheets, wherein the spring sheets 1251 have elasticity. Therefore, when the burner socket 1000 is in the closed position shown in FIG. 3 and FIG. 4A, the springs 1251 of the contact portion 1250 abut against the conductive sheets of the female socket 2200. At the same time, the springs 1251 are compressed by the female socket 2200 to produce deformation, so that the springs 1251 contact the conductive sheets with a larger contact area to form a better electrical connection, so as to provide power from the burner mainboard 2000 to various components in the heat conducting portion 1200. On the contrary, when moving from the closed position shown in FIG. 4A to the open position shown in FIG. 4B, the contact portion 1250 will gradually move away from the female socket 2200 to form a circuit break. At the same time, the springs 1251 are restored to the open position by their own elastic force. In another embodiment, the connector may be a hoe connector, that is, the contact portion 1250 is composed of a plurality of metal hoes, and the female seat 2200 is composed of a plurality of slots corresponding to the hoes. As in the aforementioned embodiment, when the hoes are inserted into the slots, the heat conducting portion 1200 is electrically connected to the burner mainboard 2000.

FIG. 5A and FIG. 5B are top views of another embodiment of the burner socket 1000 of the present invention. The burner socket 1000 and the motherboard adapter plate 2100 are fixedly connected to the burner motherboard 2000 in an adjacent manner, wherein the motherboard adapter plate 2100 is electrically connected to the burner motherboard 2000 via a crimp adapter 2300 (such as a crimp connector). In this embodiment, the heat conducting portion 1200 of the burner socket 1000 is configured to slide relative to the upper portion of the body portion 1100 along a horizontal direction a2, and the socket adapter plate 1240 is configured on the outer side surface of the heat conducting portion 1200 and parallel to the motherboard adapter plate 2100. As shown in FIG. 5A , when the burner socket 1000 slides toward the open position, the socket adapter plate 1240 can slide along the horizontal direction a2 and parallel to the upper side of the motherboard adapter plate 2100 under the drive of the heat conducting portion 1200. The socket adapter plate 1240 and the motherboard adapter plate 2100 are the same as the aforementioned embodiment, and are provided with a contact portion 1250 and a female socket 2200 of a connector corresponding to each other, wherein the connector is a spring-type connector or a spade connector. As shown in FIG. 5B , when the burner socket 1000 is in the closed position, the contact portion 1250 and the female socket 2200 contact each other to form an electrical connection. In this embodiment, the burner motherboard 2000 is electrically connected in the order of the press-fit adapter 2300, the motherboard adapter board 2100, the female socket 2200, the contact part 1250, the socket adapter board 1240, and the heat conducting part 1200 to provide power to various components in the heat conducting part 1200.

In various embodiments of the present invention, the female socket 2200 and the contact portion 1250 of the adapter can be interchangeably arranged on the heat conducting portion 1200 and the burner mainboard 2000, and even the socket adapter plate 1240 and the mainboard adapter plate 2100 are not used and can be directly arranged on the heat conducting portion 1200 and the burner mainboard 2000 to achieve the same technical effect.

In summary, compared with the prior art, the aforementioned embodiment of the present invention does not require a wire to electrically connect the burner socket and the burner mainboard. Therefore, when operating the burner socket, whether it is a pivoting operation or a sliding operation, the wire will not be excessively bent or broken due to stress. Therefore, the present invention belongs to a wireless burner socket. In addition, the configuration of the connector of the present invention can be used as an additional circuit safety mechanism and foolproof mechanism. The circuit safety mechanism is used to ensure that the burner socket is still in a circuit-breaking state when the burner test is not performed to avoid the risk of electric shock to the user. The foolproof mechanism is used to allow the user to identify whether the burner socket is in the correct closed position based on whether the connector is in a contact state in appearance. Most importantly, the configuration of the present invention is more convenient and simpler in terms of maintenance compared to the previous technology (for example, the user only needs to replace the metal spring or conductive sheet on the connector), thus extending the service life of the burner socket.

It should be noted that the aforementioned embodiments of the present invention are only used to illustrate the present invention, and are not used to limit the scope of the present invention. All modifications and changes made to the present invention by a person skilled in the art of the present invention are within the spirit and scope of the present invention. The same or similar components in different embodiments, or components represented by the same element symbols in different embodiments have the same physical or chemical properties. In addition, under appropriate circumstances, the above embodiments of the present invention can be combined or replaced with each other, rather than being limited to the specific embodiments described above. The connection relationship between a specific component described in one embodiment and other components can also be applied to other embodiments, which all fall within the scope of the present invention as attached patent application scope.
