Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector contact that improves contact stability. Background Technology

[0002] Connectors are critical components used to connect two or more devices, systems, or components, enabling the transmission of signals, current, or data. They are widely used in electronics, electrical engineering, mechanics, communications, and other fields, and are fundamental components that ensure reliable interoperability between devices.

[0003] Patent publication number CN213782433U discloses a novel contact-type connector, including an adapter. The adapter has plugs on both sides and slots at both ends. A plurality of contact plates are evenly distributed on one side of the slot, which is in contact with the plug end face. The contact plates of one slot are located on the upper end face of the slot, and the contact plates of the other slot are located on the lower end face. A plug is positioned with a insertion plate aligned with the slot, and a contact groove is positioned with the insertion plate aligned with the contact plates. A copper sheet is located inside the contact groove. The adapter and the plug are connected and fixed together by a connecting plate. The connecting plate, the adapter, and the plug are all connected together with screws. This design ensures stable contact-type connector connection, avoiding the tendency for contact connections to come loose after long-term use. Furthermore, this contact-type connection is easy to install and use, facilitating the use with wires and ensuring stable connection of the contact-type connector components.

[0004] This patent uses screws to fix the connecting plate to the adapter and plug. Manufacturing the connecting plate separately and assembling the screws additionally increases the number of parts and assembly steps, raising manufacturing costs. Accumulated tolerances across multiple components may reduce mating accuracy, negatively impacting the alignment reliability of the contact plate and copper sheet. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

A plug 1 is inserted into the slot 15, and a plug plate 16 is inserted into the slot 15. The plug plate 16 is fixedly connected to the plug 1. Multiple contact grooves 14 are provided on the top surface of the plug plate 16. Copper sheets are fixedly connected within the contact grooves 14. Contact plates 13, which contact the copper sheets, are inserted into the contact grooves 14 and are fixed to the top wall of the slot 15. A wire 8 is fixedly connected to the end of the plug 1. A fixing block 6 is fixedly connected to the top surface of the plug 1. A slot 9 is provided on the side of the fixing block 6, and a convex plate 3 is inserted into the slot 9. The convex plate 3 is slidably connected to the top surface of the adapter 4. The top surface of the adapter 4 is symmetrically provided with two first sliding grooves 12. The first slider 11 is slidably connected in the first sliding groove 12. The first slider 11 is fixedly connected to the bottom surface of the convex plate 3. A compressed first spring 10 is fixed between the first sliding groove 12 and the first slider 11. The convex plate 3 is symmetrically provided with two cavities 18. A positioning member is slidably connected in each of the two cavities 18. The positioning member is inserted into the inner wall of the slot 9. The top surface of the fixing block 6 is provided with a countersunk hole 19 that communicates with the slot 9. A fixing member is rotatably connected in the countersunk hole 19. The fixing member is inserted into the top surface of the convex plate 3.

[0024] The positioning component includes a support plate 17 slidably connected in the cavity 18, a connecting rod 5 fixedly connected to the side of the support plate 17, the connecting rod 5 slidingly passing through the cavity 18, a push block 2 fixedly connected to the end of the connecting rod 5, a second positioning pin 29 fixedly connected to the side of the support plate 17, the second positioning pin 29 slidingly passing through the cavity 18, a second positioning groove 28 provided on the inner wall of the slot 9, the second positioning pin 29 inserted into the second positioning groove 28, two third sliding grooves 26 symmetrically provided on the inner wall of the cavity 18, a third slider slidably connected in the third sliding groove 26, the third slider fixedly connected to the support plate 17, and a second spring 27 fixedly fixed between the inner wall of the third sliding groove 26 and the third slider.

[0025] The fasteners include a bolt 7 rotatably connected to a countersunk hole 19, a receiving groove 25 communicating with the countersunk hole 19 on the top wall of the slot 9, a first positioning pin 23 slidably connected in the receiving groove 25, the first positioning pin 23 being threadedly connected to the bolt 7, a protrusion of a convex plate 3 being inserted into the slot 9, and a first positioning groove 22 on the top surface of the protrusion of the convex plate 3, the first positioning pin 23 being inserted into the first positioning groove 22, a threaded groove 24 on the top surface of the first positioning pin 23, the bolt 7 being threadedly connected in the threaded groove 24, and two second sliding grooves 20 symmetrically opened on the inner wall of the receiving groove 25, a second slider 21 slidably connected in the second sliding groove 20, and the second slider 21 being fixedly connected to the first positioning pin 23.

[0026] By replacing the traditional screw-fixed connecting plate with an integrated convex plate 3 and spring sliding mechanism, the number of parts is reduced, the complexity of the assembly process is lowered, and the manufacturing cost is effectively controlled. At the same time, the problem of tolerance accumulation of multiple parts is avoided. Through the cooperation of the first slider 11, the first slide groove 12 and the compression spring, the plug 1 and the adapter 4 are always kept in an elastic pressing state, dynamically compensating for wear or tolerance. The first spring 10 provides axial pressing force for the plug 1 and the adapter 4, ensuring that the contact plate 13 and the copper sheet are tightly attached, reducing contact resistance. The second positioning pin 29 in the positioning component is precisely aligned with the second positioning groove 28. Combined with the buffer of the second spring 27 in the third slide groove 26, the alignment reliability of the contact plate and the copper sheet is further guaranteed. The second spring 27 ensures the radial reset accuracy of the positioning pin and reduces signal transmission fluctuations. The convex plate 3 drives the first positioning pin 23 to insert into the first positioning groove 22 through the bolt 7 of the fixing component, forming a mechanical interlock. The thread self-locking characteristic prevents loosening under vibration environment and avoids accidental disengagement of the plug 1. It is especially suitable for vibration environment. The dual positioning design distributes the force and extends the service life.

[0027] Working principle: In use, first insert the plug plate 16 at the end of the plug 1 into the slot 15 in the adapter 4. Then, press the two push blocks 2 simultaneously, causing the two push blocks 2 to drive the two connecting rods 5 to move the two support plates 17 relative to each other. At the same time, the second spring 27 is compressed, so that the end of the second positioning pin 29 is flush with the side wall of the convex plate 3. Then, push the convex plate 3 so that the protrusion of the convex plate 3 is inserted into the slot 9 in the fixing block 6. At the same time, the first spring 10 is compressed. Then, release the two push blocks 2 respectively, and the second spring 27, which was in a compressed state, returns to its original state. When the two support plates 17 are pushed to move in opposite directions, the support plates 17 drive the second positioning pin 29 to be inserted into the second positioning groove 28 in the slot 9. Then the bolt 7 is rotated, and the bolt 7 drives the first positioning pin 23 to descend through the threaded groove 24. The first positioning pin 23 is inserted into the first positioning groove 22 on the top surface of the protrusion of the convex plate 3, which fixes the connection between the adapter 4 and the plug 1. At this time, the first spring 10 in the compressed state will generate a pulling force towards the inside of the slot 15, so that the plug 1 and the adapter 4 fit tightly together, thereby improving the stability and fit of the contact plate 13 and the contact groove 14.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
