Description

electrical connector

technical field

The utility model relates to electromechanical products, in particular to an electrical appliance connector.

Background technique

As we all know, the commonly used electrical connectors have no obvious signs or devices to indicate the direction of the connection when connecting, so the connectors are easily reversed by the user and the equipment is damaged; in addition, after the male and female connectors are connected, they are easily pulled by external forces If it falls off, the power or signal cannot be input or output, and the equipment cannot be used, which needs to be improved.

Utility model content

The purpose of this utility model is to provide an electrical connector, which solves the problem that the existing electrical connector joints are easily reversed by the user and the equipment is damaged. After the male and female connectors are connected, they are easily pulled by external forces and fall off, resulting in the failure of power or signal input. or output, resulting in problems such as unusable equipment.

The structure of the utility model is composed of plugs, connectors and wire connectors, wherein the plug is provided with flanges, bumps, sockets, pin grooves and buckling feet; the connector is provided with grooves, pins, pins, and card holes and the fixed side; the wire connector is provided with buckles and chucks; when the plug is inserted into the connector, since the flange is located on the side of the plug close to the top surface, the corresponding groove is set on the side of the connector close to the top surface When the connection is correct, the flange penetrates into the groove. When the connection is reversed, the flange forms a mutual resistance with the opening surface of the connector, and the plug cannot be inserted into the connector, preventing the use of the connector. On the contrary; the utility model has a convex point on the pin slot, which is stuck in the clamping hole of the joint, and further prevents the plug from falling off from the joint; after the jack on the pin slot is inserted into the joint by the plug, the pins in the joint It is clamped on the collet of the cable connector through the jack to facilitate signal transmission; and the buckle on the cable connector is fastened with the buckle pin of the plug after the cable connector is inserted into the plug to prevent the cable connector from falling off.

The utility model has the advantages of: it has an anti-reverse connection device, which can prevent the user from reversely connecting the joints and causing damage to the equipment; it can achieve a tighter combination, so that the joints will not be loose, and has strong practicability.

Detailed ways:

As shown in accompanying drawings 1 and 2, the utility model is composed of a plug A, a joint B and a wire joint C, wherein the plug A is provided with a flange A1, a bump A2, a jack A3, and a pin slot A4 and buckle pin A5; connector B is provided with groove B1, pin B2, pin B3, card hole B4 and fixed edge B5; line connector C is provided with buckle C1 and chuck C2; when plug A is inserted into connector B, due to The position of the flange A1 is set on the side of the plug A close to the top surface, and the corresponding groove B1 is set on the side of the connector close to the top surface to form a structure to prevent reverse connection. When the connection is correct, the flange A1 will pass through. into the groove B1, when the connection is reversed, the flange A1 forms a mutual resistance with the opening surface of the connector B, and the plug A cannot be inserted into the connector B, preventing the user from reverse connection; the utility model is on the pin groove A4 There is a convex point A2, which is stuck in the hole B4 of the connector B, so as to further prevent the plug A and the connector B from falling off; the jack A3 on the pin groove A4 is inserted into the connector B after the plug A is inserted, so that the pins in the connector B B3 is clamped on the clamp C2 of the cable connector C through the socket A3, which is convenient for signal transmission; and the buckle C1 on the cable connector C is inserted into the plug A, and forms a buckle with the buckle pin A5 of the plug A. to prevent wire connector C from falling off.

As shown in Figure 3, after the plug A is inserted into the connector B, there is a bump A2 on the pin groove A4, which is stuck in the hole B4 of the connector B, so as to further prevent the plug A and connector B from falling off, and the wire connector The buckle C1 on C forms a buckle with the fastening foot A5 of the plug A after the wire connector C penetrates into the plug A, so as to prevent the wire connector C from falling off.

As shown in accompanying drawing 4 and accompanying drawing 5, the connector of the present invention can further be set as connector D and E, and its plug D1 and E1 can be set as 3, 4 or more pin grooves according to manufacturer's demand, It and the connectors D2 and E2 need to match the plugs D1 and E1 to be set to the same width, forming a design of multiple sets of pin slots.

As shown in Figure 6, the connector F of the present invention is further configured such that the pin F1 is perpendicular to the connector F and the fixed edge F5 extends the pin F2, so as to facilitate fixing the connector F on circuit boards and other related equipment.
