Description

High Frequency Floating Contacts for Connectors

technical field

The utility model relates to the field of electrical connectors, in particular to a high-frequency floating contact piece for connectors.

Background technique

Due to its advantages of high frequency of use and small size, high-frequency contacts are increasingly used in high- and low-frequency mixed electrical connectors. Existing high and low frequency mixed electrical connectors such as "a high and low frequency mixed electrical connector plug" disclosed in Chinese patent CN102035092A, the plug includes a high frequency contact piece, the high frequency contact piece includes a fixed shell and can be moved through a floating mechanism. Axially floating floating part assembled on the fixed shell, the floating part includes the floating shell and the inner conductor installed in the floating shell through the insulation of the insulator, the floating mechanism includes the top installed between the floating shell and the fixed shell The spring and the bottom end are press-fitted and fixed on the limit block on the fixed shell. The top of the limit block is everted to limit the barb of the limit block, and the bottom of the floating shell is everted to cooperate with the barb of the limit block to limit the floating. Housing barbs at the upper limit of housing travel. When the mixed electrical connector plug is mated and mated, the floating housing is moved downward by the positive pressure generated by the mating and compresses the spring, and the spring generates an upward reaction force to make the high-frequency contact and the mating contact dock in place. The existing problem of this kind of high-frequency contact is: in order to realize the anti-off of the floating shell relative to the fixed shell, the floating shell and the limit block are respectively provided with a shell barb and a limit block barb, During assembly, it is necessary to press fit the floating housing and the limit block in place, so that the barb can play the role of limit. The setting of the limit block and each barb increases the structural complexity of the high-frequency contact piece, and at the same time It also makes it difficult to assemble the high-frequency contact piece, and it is not easy to disassemble and maintain.

Contents of the invention

The purpose of the utility model is to provide a high-frequency floating contact piece for a connector with a simple structure.

In order to solve the above problems, the technical solution of the utility model is:

The high-frequency floating contact piece for connectors includes a fixed housing and a floating housing that is floatingly assembled on the fixed housing and contains an inner conductor. It is characterized in that: the fixed housing has an axis extending along the front and rear A guide hole for the floating shell to guide and wear from the back to the front, and the fixed shell is provided with a shell stop structure that cooperates with the floating shell to limit the forward movement limit of the floating shell. A snap ring is detachably mounted on the floating housing in front of the housing stop structure, and a floating spring is mounted on the periphery of the floating housing between the snap ring and the fixed housing.

The casing stop structure includes an annular boss arranged on the hole wall of the guide hole, and the floating casing is provided with an annular step for stopping and cooperating with the rear end surface of the annular boss.

The floating spring is mounted between the snap ring and the front end of the annular boss.

The said fixed housing is integrally provided with a protective sleeve which is arranged around the periphery of the said floating spring.

The beneficial effects of the utility model are: when the high-frequency floating contact piece in the utility model is assembled, the floating shell is inserted into the guide hole on the fixed shell from back to front, and the shell on the fixed shell The stop structure cooperates with the floating shell to limit the forward movement limit of the floating shell, and then installs a floating spring on the periphery of the floating shell on the fixed shell, and finally installs a snap ring on the floating shell to fix the floating spring That's it. The high-frequency floating contact piece has a simple structure, is convenient to disassemble and assemble, and is easy to maintain.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model. the

Detailed ways

The embodiment of the high-frequency floating contact for the connector is shown in Figure 1: it includes a fixed housing 7 and a floating component floating on the fixed housing. For the inner conductor 3 in the floating shell, the fixed shell is provided with a guide hole whose axis extends along the front-to-back direction and is used for the floating shell to guide and wear from the back to the front. The hole wall of the guide hole is provided with an annular boss 6 , the floating shell is provided with an annular step 8-1 for blocking and cooperating with the rear end surface of the annular boss, and the annular boss constitutes a shell stop structure for limiting the forward movement limit of the floating shell. On the floating housing, a snap ring 4 is detachably mounted in front of the annular boss, and a floating spring 2 is mounted on the outer periphery of the floating housing between the snap ring and the front end of the annular boss, and the fixed housing is integrally provided with The protective sleeve 5 which is arranged around the periphery of the floating spring.

In other embodiments of the present utility model: the housing stop structure can also be formed by the rear end surface of the fixed housing. The annular boss; the protective sleeve can also be omitted; the floating spring can also be top-mounted between the snap ring and the front end of the fixed housing.
