Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

Please refer to Figures 1-7. A compact heavy-duty connector of the present invention includes a connector body 1. The upper end of the connector body 1 is provided with an upper cover 2. The upper cover 2 is provided with a plurality of The docking slot 3 is provided with a limiting component inside, and a cavity 4 is provided on the inner wall of the docking slot 3. The limiting component includes a positioning frame 15, a driving block 5 and a positioning plate 13. The positioning frame 15 is fixed inside the docking groove 3. The lower end of the positioning frame 15 is provided with a connecting pipe 6 inserted into the interior of the connector body 1. The connecting pipe 6 is provided with a bottom groove 7 inside. The positioning frame 15 A limiting plate 17 and a bottom block 16 are fixedly provided on one side of the 9. A stopper 10 is fixedly provided at the bottom of the empty slot 9. The top of the positioning plate 13 is provided with an arc-shaped piece 12 located inside the empty slot 9. The front end of the arc-shaped piece 12 is provided with an elastic piece 11, and The stopper 10 is located on the top of the elastic piece 11, the bottom block 16 penetrates the hook 14, and the limiting plate 17 is located at the rear end of the positioning plate 13. The bottom of the slot 9 is provided with a penetrating arc piece 12 The positioning shaft 18. When using this structure, insert the wire plug that needs to be docked into the docking slot 3, so that the wire plug can be further inserted into the bottom slot 7. During the insertion process, the wire plug will squeeze the elastic piece 11 , can cause the elastic piece 11 to produce elastic deformation. At this time, the elastic piece 11 will shrink inward to a certain extent. Through the rebound effect of the elastic piece 11, the wire plug can be fixed more firmly inside the docking slot 3. Compared with traditional screws, In terms of fixation, this structure has obvious improvement in efficiency and anti-seismic effect, and can improve the stability of the connector body 1 during use. When it is necessary to separate the wire plug, press the driving block 5. At this time, the driving block 5 The stopper 10 is driven to press down the elastic piece 11. Since the part of the positioning plate 13 that contacts the limiting plate 17 has a certain arc, and the hook 14 penetrates the bottom block 16, the position of the positioning plate 13 is fixed. When the driving block 5 is pressed down, The elastic piece 11 can continue to be retracted and deformed. At this time, the wire plug in the docking slot 3 can be pulled out. The assembly efficiency is high. The driving block 5 can be fixed on the arc piece 12 through the positioning shaft 18 provided.

The top of the driving block 5 lacks a force point, which makes the driving block 5 difficult to operate. The top of the driving block 5 is provided with a groove 8, and the groove 8 is a trapezoidal structure. Through the provided groove 8, a force point can be provided at the top of the driving block 5, so that the driving block 5 is easy to operate. Specifically, the driving block 5 can be pressed down with a flat-blade screwdriver or other smaller round rod.

In this structure, the elastic piece 11, the arc piece 12, the positioning plate 13 and the hook 14 are an integrated structure. The elastic piece 11, the arc piece 12, the positioning plate 13 and the hook 14 can be made of elastic steel pieces. , can make the elastic piece 11 have a good rebound effect.

Furthermore, the inner wall of the groove 8 is provided with anti-slip patterns.

In this structure, the inner wall of the docking groove 3 is provided with a step buckle corresponding to the driving block 5. Since the wire plug has a plurality of self-contained grooves 8, through the cooperation of the grooves 8 and the step buckle, the The wire plug is more secure in the docking slot 3, and the size of the step buckle is not mandatory here.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
