Description

Connectors for connecting cables

technical field

The embodiment of the utility model relates to a connector, in particular, relates to a connector for connecting wires.

Background technique

In electronic equipment, to facilitate the electrical connection of two cables, usually the two cables are respectively connected to a plug connector and a socket connector. The electrical connection of the two cables is achieved through mutual cooperation between the plug connector and the socket connector. In some cases, connectors are used to connect the cables to the printed circuit board.

Generally, a connector includes an insulating housing and a plurality of conductive terminals disposed in the insulating housing. During the connection process between the cable and the plug or socket connector, the cable is stripped of the insulation layer to expose the wires, and the wires are inserted and electrically connected to the conductive terminals of the plug connector or socket connector in the insulating housing, through the conductive terminals and The connection of the conductive terminals of the mating receptacle connector or plug connector makes the electrical connection between the cables.

In existing electrical connectors, inserted wires are kept electrically connected to the conductive terminals by piercing features provided on the conductive terminals. However, at the initial stage when the conductive terminal is inserted into the conductive terminal, due to the large internal space of the conductive terminal, the insertable space and angle of the wire are relatively large. In this way, when the wire is inserted into the conductive terminal in an inclined and deviated posture, the piercing characteristics of the conductive terminal will be damaged, resulting in a large plastic deformation of the conductive terminal, thereby reducing the contact force, and in severe cases, it will cause poor contact. When the wire is forced to swing or rotate, the force on the wire will directly act on the piercing part of the conductive terminal, that is, the electrical connection part, which will further cause the instability of the electrical connection between the wire and the conductive terminal, and affect the electrical connection of the connector. Connection performance is affected.

In addition, in an existing electrical connector including an insulating housing, a wire is inserted into the insulating housing from a socket at one end of the insulating housing and is electrically connected to a connection terminal provided in the insulating housing. Because it is difficult to seal the wire and the socket, when the connector is used in a humid environment, external impurities such as moisture can easily enter the interior of the insulating housing from the socket, thereby adversely affecting the electrical performance of the connector .

4, 11-15, the plug part 31 of the connector 100 is provided with a cantilever 33 extending in the insertion direction of the cable 200 on the outside of the first insulating housing 30, and the outer side of the cantilever 33 is provided There are blocking steps 331 . The cantilever 33 has a substantially L-shape and is integrally connected with the first insulating case 30 . On the other hand, the second insulating housing 50 of the mating connector 500 is provided with a positioning frame 53, and the cantilever 33 of the connector 100 passes through the positioning frame 53 during the process of combining the connector with the mating connector. , and after the cantilever 33 passes through the positioning frame 53, the blocking step 331 of the cantilever 33 abuts against the positioning frame 53 to prevent the cantilever 33 from detaching from the positioning frame 53, thereby connecting the connector and the mating connector hold together firmly.

In a further embodiment, a protrusion 54 is provided on a side of the positioning frame 53 that is far away from the second socket 511 of the second receiving channel. When the connector 100 connected with the cable 300 is combined with the mating connector 500 connected with the mating cable 600 , the end 332 of the cantilever 33 abuts against the protrusion 54 to prevent the blocking step 331 of the cantilever 33 Detach from the positioning frame 53. When it is necessary to separate the connector 100 from the mating connector 500 , the part of the cantilever 33 located between the positioning frame 53 and the protrusion 54 can be pressed, so that the cantilever 33 is bent downward. In this way, the blocking step 331 of the cantilever 33 can be driven to disengage from the positioning frame 53, allowing the connector to be separated from the mating connector.

13-15, except for the contact portion, the conductive terminal 20 and the mating conductive terminal 60 have the same structure. In detail, the contact portion 28 of the conductive terminal 20 includes a pair of third clamping arms 281 extending obliquely from the side of the third side wall away from the first end; 68 includes a pair of clamped arms extending in parallel from the mating conductive terminal 60, and the clamped arms are clamped between a pair of third clamping arms 281 of the contact portion 28 of the conductive terminal 20 of the connector 100. , so as to realize the electrical connection between the conductive terminal 20 and the mating conductive terminal 60 .

When the connector 100 is combined with the mating connector 500, the third clamping arm 281 of the contact portion 28 of the connector 100 clamps the clamped arm of the contact portion 68 of the mating connector 500, so that the conductive terminal 20 and the mating conductive terminal 60 to maintain good electrical contact. In this way, the cables 200 connected to the conductive terminals 20 are respectively electrically connected to the mating wires 600 connected to the mating conductive terminals 60 , realizing a wire-to-wire electrical connection between the wires 200 and the mating wires 600 . Therefore, the connector assembly shown in FIGS. 11-15 belongs to a type of wire-to-board connector. In an alternative embodiment, the contact portion of the mating connector is configured as a clamping arm, and the contact portion of the connector is configured as a clamped arm.

In one embodiment, the connector described above may be a plug connector, and the mating connector may be a socket connector mated with the plug connector. In another alternative embodiment, the connector described above may be a socket connector, and the mating connector may be a plug connector mated with the socket connector.
