Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector that can be used for signal or electrical connection. Background Art

[0002] Connectors are generally used to connect two devices to transmit current or signals. In the field of signal connectors, existing connectors generally have one end welded with a circuit board to be fixed on the main body of active devices such as socket boards and computers; the other end is set as a socket structure for the access of plugs such as crystal plugs of network cables and telephone lines. Current technological development has higher and higher requirements on the life, quality and utilization rate of connectors, but existing connectors have the following shortcomings:

[0003] 1. One end of the existing connector is welded on the circuit board, which makes it inconvenient to replace, and the welding point between the connector and the circuit board is easy to break, resulting in a short service life;

[0004] 2. Since one end of the connector is welded on the circuit board, the position is relatively fixed. Due to the influence of the position, it cannot be replaced to other places under special circumstances;

[0005] 3. The socket structure of the existing connector is single, and the connection method of the plug such as the crystal head connected to it is also relatively single, which can only be used for the connection of the plug that is compatible with the socket structure of the connector, and has poor applicability;

[0006] 4. Existing connectors generally cannot meet the connection requirements of multiple groups of signal terminals. When multiple groups of signal terminals need to be connected, multiple groups of connectors are generally required, which increases the connection cost. Utility Model Content

When signal lines of different models need to be connected, there is no need to replace the entire connector, and the plug-in component of the shell 1 can be replaced as needed, thereby reducing maintenance costs.

[0062] Further, such as Figure 4-8As shown, the plug assembly 2 includes an adapter 22 and a socket pressure plate 23 arranged in pairs. The electrical connection element 21 is arranged on the adapter 22, and the plug terminals 211 formed at the opposite ends of the adapter 22 of the electrical connection element 21 are arranged opposite to each other. As required, the plug terminals 211 can be inclined at an angle to the first direction (such as Figure 4 The socket pressure plate 23 has a first end and a second end opposite to each other. The first end of the socket pressure plate 23 is provided with a plug-in cavity 231 for plugging in the plug-in terminal 211 at one end of the adapter 22. The second end of the socket pressure plate 23 is formed as a socket 232, and the socket 232 is connected to the plug-in cavity 231.

[0064] Furthermore, the plug-in cavity 231 and the socket 232 provided on the socket pressure plate 23 are one or more groups, which facilitates the connection of multiple groups of signal lines and improves applicability.

[0065] In a possible embodiment, the plug-in cavity 231 of the socket pressure plate 23 includes a first cavity 231a adapted to the adapter 22 and a plurality of groups of slots 231b adapted to the plug-in terminals 211, wherein the slots 231b are connected to the first cavity, and a blocking portion 231c is provided at the end of the first cavity 231a located at the second end of the socket pressure plate 23 to realize the positioning of the adapter 22 and ensure the stability and reliability of the plug-in between the adapter 22 and the socket pressure plate 23.

[0066] In a possible embodiment, the outer wall of the adapter 22 is provided with a limiting protrusion 221 to limit the plugging position of the adapter 22. Preferably, the limiting protrusion 221 is provided at the center position of the adapter 22 along the first direction, and the limiting protrusion 221 protrudes outside the plugging cavity 231 of the socket pressure plate 23, so that when the adapter 22 is plugged into the socket pressure plate 23, the limiting protrusion 221 on the adapter 22 is blocked outside the plugging cavity 231, thereby limiting the plugging position of the adapter. Figure 5 As shown, the limiting protrusion 221 protrudes from the outside of the first cavity 231a of the socket pressure plate 23. When the adapter 22 is plugged into the socket pressure plate 23, the limiting protrusion 221 on the adapter 22 abuts against the surface next to the first cavity 231a of the socket pressure plate 23, and the plugging is completed (as shown in FIG. Figure 7As shown), the stability and reliability of the plugging of the adapter 22 and the socket pressure plate 23 are ensured.

When the limiting rib 234 provided on the outer side of the socket pressure plate 23 is inserted into the limiting groove 111 in the mounting cavity 11 of the housing 1, the housing 1 returns to its original state, realizing the positioning connection between the socket pressure plate 23 and the housing 1. In order to facilitate the insertion of the socket pressure plate 23 into the mounting cavity 11 of the housing 1, the insertion end of the limiting rib 23 is an inclined surface, and the other end is a flat surface.

[0071] The installation method of the connector is as follows: insert one end of the adapter 22 from the plug-in cavity 231 of the first socket pressure plate 23 of the paired socket pressure plates 23.
