Description

Technical Field

[0001] The utility model belongs to the technical field of electrical component equipment, and in particular relates to an electrical connector. Background Art

[0002] Electrical connectors are mainly used for electrical connection and signal transmission between devices, components, and systems, and are essential basic components for a complete system. The electrical connectors in the related art are composed of a fixed-end electrical connector, i.e., a female contact (referred to as a socket), and a free-end electrical connector, i.e., a male contact (referred to as a plug). The socket is fixed to the electrical component through its square (round) disk (some are also welded), and the plug is generally connected to the cable, and the plug and socket are connected by connecting the nut.

[0003] Chinese utility model patent CN218828121U discloses an electrical connector, including: a socket assembly, a plug assembly, and a clamping assembly. The socket assembly includes a socket body and a screw. The outer wall of the socket body is connected to a protective shell, the inner side of the socket body is provided with a plug-in slot, the inner side of the socket body is provided with a wire-passing inner hole, the inner wall of the plug-in slot is connected to a slot cushion, one end of the positioning top plate is connected to a plug-in top block, the lower end of the positioning top plate is connected to an assembly card block, and the clamping assembly includes a clamping cushion.

[0004] In the above technical solution, the clamping assembly is fixed in the socket body by a plurality of screws. However, this fixing method makes the installation and removal process of the clamping assembly too troublesome and cannot fix cables of different diameters. Utility Model Content

[0005] The purpose of the utility model is to provide an electrical connector in view of the above-mentioned technical problems, so that the clamping assembly can be easily installed or removed in the socket body and cables with different diameters can be clamped.

[0006] In view of this, the utility model provides an electrical connector, comprising: a socket body, the outer wall of the socket body is connected to a protective shell, the front of the socket body is provided with a plurality of circular through grooves, the bottom of the circular through grooves is provided with wire holes, and the utility model is characterized in that it also includes:

[0007] A connecting tube, wherein an upper arc plate and a lower arc plate are symmetrically mounted on the inner wall of the connecting tube;

[0008] A clamping assembly, which is used to clamp and fix the cables placed on the lower arc plate;

[0009] Among them, the outer wall of the connecting tube at one end close to the socket body is provided with an external thread, the inner wall of the circular through groove is an internal thread, and the external thread is in opposite directions to the internal thread.

[0010] In the present technical solution, the outer wall of the connecting tube is provided with an external thread, and the inner wall of the circular through groove is an internal thread, and the two are in opposite directions. Therefore, the clamping assembly can be installed or disassembled in the socket body by rotating the connecting tube. The operation is simple and convenient, and under the action of the clamping assembly, cables of different diameters placed on the lower arc plate can be clamped and fixed.

[0011] In the above technical solution, further, the clamping assembly includes:

[0012] A connecting rod that penetrates the upper arc plate and the connecting tube and extends outside the connecting tube, wherein one end of the connecting rod is fixedly connected to the clamping plate and the other end is fixedly connected to the knob;

[0013] A fixed block symmetrically mounted on both sides of the connecting rod, one end of the fixed block is connected to the connecting tube, and the other end is slidably connected to a guide rod, and the outer end of the guide rod is connected to a transverse plate;

[0014] Wherein, the connecting rod is threadedly connected to the transverse plate.

[0015] In the present technical solution, when the cable is placed on the lower arc plate and needs to be compressed, the user can adjust the position of the connecting rod by rotating the knob. Since the connecting rod is threadedly connected to the cross plate, rotating the knob will cause the connecting rod to move along its axial direction, so that the clamping plate moves downward to clamp and compress cables of different diameters. The movement of the connecting rod will push the guide rod to slide in the fixed block. Since the fixed block is connected to the connecting tube, the sliding of the guide rod will be smooth and linear.

[0016] In the above technical solution, further, a rubber pad is fixedly connected to the inner side of the clamping plate.

[0017] In the present technical solution, the rubber pad can effectively increase the friction between the clamping plate and the cable, prevent the cable from sliding or loosening during the compression process, and reduce the local pressure on the cable to avoid damage to the cable.

[0018] In the above technical solution, further, the lower arc plate is provided with a plurality of arc grooves, and balls are roamingly installed in the arc grooves, wherein a part of the balls is exposed on the inner wall of the lower arc plate.

[0019] In the present technical solution, when the clamping plate presses and fixes the cable on the lower arc plate, the ball is in direct contact with the cable, reducing the friction between the cable and the lower arc plate, and when the cable is pulled out and moved, the friction of the cable can be reduced, thereby achieving the effect of protecting the insulating layer on the outer surface of the cable.

[0020] In the above technical solution, further, a sealing ring is provided at the bottom of the circular through groove, and a sealing groove matched with the sealing ring is provided at one end of the connecting tube close to the circular through groove.

[0021] In this technical solution, the sealing ring at the bottom of the circular through groove and the sealing groove at the end of the connecting tube cooperate with each other. When the connecting tube is screwed into the socket body, the sealing ring is pressed tightly in the sealing groove, thereby improving the sealing performance of the equipment.

[0022] In the above technical solution, further, a rolling groove is provided on the inner wall of the connecting cylinder, and a plurality of rollers are rotatably connected in the rolling groove.

[0023] In the technical solution, a plurality of rollers are rotatably connected to the rolling groove to further increase the friction force of the cable when the connecting cylinder is extracted and moved, thereby reducing the direct friction between the inner walls of the connecting cylinder.

[0024] The beneficial effects of the utility model are:

[0025] 1. The outer wall of the connecting tube is provided with an external thread, and the inner wall of the circular through groove is an internal thread, and the two are in opposite directions. Therefore, the pressing assembly can be installed or removed in the socket body by rotating the connecting tube, which is simple and convenient to operate.

[0026] 2. After the cable is placed on the lower arc plate, if it needs to be compressed, the user can adjust the position of the connecting rod by rotating the knob. Since the connecting rod is threadedly connected to the cross plate, rotating the knob will cause the connecting rod to move along its axial direction, so that the clamping plate moves downward to clamp and compress cables of different diameters. The movement of the connecting rod will push the guide rod to slide in the fixed block. Since the fixed block is connected to the connecting tube, the guide rod will slide smoothly and linearly.
