Description

Technical Field

[0001] This utility model relates to the field of connector structure technology, and in particular to a waterproof limiting connection structure for connector contacts. Background Technology

[0002] A connector is an electrical component consisting of two parts: a plug and a connector. Normally, they are completely separable. Switches and connectors are similar in that they switch circuits by changing the contact state of their contact pairs. However, the fundamental difference is that connectors only have two states: insertion and removal. Switches can switch circuits on their own bodies, while connectors cannot. The contact pairs of connectors have a fixed correspondence. However, most existing connector failures are caused by short circuits due to water ingress into the connector. To solve this problem, we designed a waterproof limiting connection structure for connector contacts.

[0003] Chinese utility model patent CN201922239445.6 discloses a waterproof connector, including a protective shell, a terminal disposed within the protective shell, a wire clamp, a waterproof component, and a tail sleeve. The wire clamp and the waterproof component are both housed within the protective shell, which has a partition. The wire clamp is positioned between the partition and the waterproof component, and the wire clamp and the protective shell jointly position the terminal. The tail sleeve is fitted onto the waterproof component and detachably fixed to the protective shell. This utility model also provides a connector equipped with this waterproof connector. Due to the inclusion of the waterproof component and sealing ring, it achieves a good waterproof effect. Moreover, the connector has a simple structure and can be quickly assembled through the assembly of the wire clamp, waterproof component, and tail sleeve, and it can prevent misalignment. However, this utility model has the following problems: Firstly, it lacks waterproof performance. If the connector is not properly inserted, moisture can easily enter the interior of the connector structure through gaps, causing a short circuit. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by setting a first limiting groove and a first positioning hole, a second limiting groove and a second positioning hole, a rubber pad, a first break, a second break, and a third break, thereby solving the technical problem of water entering the connector and causing a short circuit due to improper insertion of the existing plug-in components.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A waterproof limiting connection structure for connector contacts includes a male connector and a female connector, characterized in that: the male connector has a plug interface on its left side, a first positioning block is provided in the middle of the upper and lower outer surfaces of the plug interface, a second positioning block is provided on the right rear side of the first positioning block, the female connector has a plug groove at its front end, a conductive part is provided at the bottom of the plug groove, and waterproof rubber parts are provided on both the upper and lower groove surfaces of the plug groove.

[0007] As a preferred embodiment, the inner rear surface of the connector is provided with four conductive pins, the inner lower surface of the connector is provided with a first limiting block, and the inner right surface of the connector is provided with two second limiting blocks, which are symmetrically arranged vertically.

A second break is provided to the right of the first break, which is located to the second positioning hole. The end of the waterproof rubber part near the conductive part is symmetrically provided with a first groove, and a second groove is provided behind the first groove. A third break is provided between the first and second grooves, and the third break is located at the rear end of the first break.

[0011] As a preferred embodiment, the front end of the conductive part is provided with four cross-shaped sockets, which are symmetrical in pairs. The cross-shaped sockets are provided with rubber pads inside, and the middle of the rubber pads is provided with rectangular grooves. The size of the rectangular grooves is adapted to the conductive feet.

[0012] As a preferred embodiment, the left end of the conductive part is provided with a first limiting groove symmetrically arranged vertically, and the lower end of the conductive part is provided with a second limiting groove. The second limiting groove is adapted to connect to the second positioning hole, and the first limiting groove is adapted to connect to the first positioning hole.

[0013] The beneficial effects of this utility model are:

[0014] (1) In this utility model, by setting a first limiting groove and a first positioning hole, a second limiting groove and a second positioning hole, the relative position of the conductive part and the plug interface is limited, ensuring that the conductive foot can be inserted into the rectangular groove of the cross socket, so that when plugged in, the conductive foot can contact the contact point inside the conductive part to realize power supply.

[0015] (2) By setting a rubber pad, the rubber product has good deformation ability, which makes the conductive foot and the cross socket tightly connected, preventing moisture from entering the interior of the conductive part from the gap between the two if the plug is not properly inserted, thus causing a short circuit.

[0016] (3) In this utility model, by setting No. 1 break, No. 2 break, and No. 3 break, during the process of gradually inserting the male connector and the female connector, when the No. 1 positioning block is inserted into the No. 1 positioning hole, the No. 1 break is squeezed and deformed, so that the No. 1 positioning block enters the No. 1 groove. When the No. 2 positioning block is gradually inserted into the No. 2 positioning hole, the No. 2 break is squeezed and deformed, so that the No. 2 positioning block enters the No. 1 groove. At the same time, the No. 1 positioning block enters the No. 2 groove through the No. 3 break, so that the male connector and the female connector are inserted into place.

[0017] In summary, this utility model has the advantages of simple structure, fast positioning, and good waterproof performance, and is especially suitable for the field of connector structure technology. Attached Figure Description

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figures 1 to 5As shown, this utility model provides a waterproof limiting connection structure for connector contacts, including a male connector 1 and a female connector 2. When the two are plugged in, electricity can be passed through. The male connector 1 has a plug interface 11 on its left side. The middle of the upper and lower outer surfaces of the plug interface 11 has a first positioning block 12, which works in conjunction with a second groove 234. The right rear side of the first positioning block 12 has a second positioning block 13, which works in conjunction with a first groove 233. The front end of the female connector 2 has a plug groove 21. The bottom of the plug groove 21 has a conductive part 22. The conductive part 22 has four contacts inside. When the contacts contact the conductive feet 14, electricity can be passed through. The upper and lower surfaces of the plug groove 21 are provided with waterproof rubber parts 23, which have a waterproof effect on the upper and lower positions of the plug groove 21 and also limit the positions of the first positioning block 12 and the second positioning block 13.

[0027] Furthermore, such as Figure 3 As shown, the inner rear surface of the connector 11 is provided with four conductive pins 14, and the lower inner surface of the connector 11 is provided with a first limiting block 15, which works in conjunction with the second limiting groove 224. The right inner surface of the connector 11 is provided with two second limiting blocks 16, which are symmetrically arranged and work in conjunction with the first limiting groove 223.

[0028] Furthermore, such as Figure 2 As shown, the upper end of the male connector 1 is provided with a second connector 17 for connecting other electrical components, and the lower end of the second connector 17 is provided with a heat dissipation connecting rib 18, which plays a good role in heat dissipation and reinforcement.

[0029] Furthermore, such as Figure 4 As shown, the front end of the connecting female head 2 is provided with a first positioning hole 24 symmetrically arranged vertically, and a second positioning hole 25 is provided on the right side of the first positioning hole 24.

[0030] Furthermore, the front end of the waterproof rubber part 23 is symmetrically provided with a first break 231, which is located to the left of the first positioning hole 24. A second break 232 is provided to the right of the first break 231, which is located in the second positioning hole 25. The end of the waterproof rubber part 23 near the conductive part 22 is symmetrically provided with a first groove 233. A second groove 234 is provided behind the first groove 233. A third break 235 is provided between the first groove 233 and the second groove 234, and the third break 235 is located in the first positioning hole 25. During the gradual insertion of male connector 1 and female connector 2 at the rear end of the break 231, when the first positioning block 12 is inserted into the first positioning hole 24, the first break 231 is deformed by compression, causing the first positioning block 12 to enter the first groove 233. When the second positioning block 13 is gradually inserted into the second positioning hole 25, the second break 232 is deformed by compression, causing the second positioning block 13 to enter the first groove 233. At the same time, the first positioning block 12 enters the second groove 234 through the third break 235, thus connecting male connector 1 and female connector 2 are properly inserted.

[0031] Furthermore, such as Figure 4 As shown, the front end of the conductive part 22 is provided with four cross sockets 221, which are symmetrical in pairs. The cross sockets 221 are provided with rubber pads 222 inside. The middle of the rubber pads 222 is provided with rectangular grooves 225. The size of the rectangular grooves 225 is adapted to the conductive feet 14. The rubber pads 222 are made of rubber and have good deformation ability, so that the conductive feet 14 and the cross sockets 221 are tightly connected, preventing moisture from entering the interior of the conductive part 22 from the gap between them and causing a short circuit if the connection is not in place.

[0032] Furthermore, the left end of the conductive part 22 is symmetrically provided with a first limiting groove 223, and the lower end of the conductive part 22 is provided with a second limiting groove 224. The second limiting groove 224 is adapted to connect to the second positioning hole 25, and the first limiting groove 223 is adapted to connect to the first positioning hole 24, thereby limiting the relative position of the conductive part 22 and the plug interface 11, ensuring that the conductive foot 14 can be inserted into the rectangular groove 225 of the cross socket 221, so that when plugged in, the conductive foot 14 can contact the contacts inside the conductive part 22 to realize power supply.

[0033] Working process: First, align the first limiting groove 223 with the first positioning hole 24, so that the second limiting groove 224 aligns with the second limiting hole 25; further, gradually insert the plug interface 11 into the plug groove 21, so that the conductive foot 14 gradually engages with the pebble socket 221; simultaneously, the first positioning block 12 is inserted into the first positioning hole 24, so that the first break 231 is compressed and deformed, so that the first positioning block 12 enters the first groove 233; further, the second positioning block 13 is gradually inserted into the second positioning hole 25, so that the second break 232 is compressed and deformed, so that the second positioning block 13 enters the first groove 233; simultaneously, the first positioning block 12 enters the second groove 234 through the third break 235, so that the conductive foot 14 makes contact with the internal contact of the conductive part 22, realizing the insertion of the male connector 1 and the female connector 2.
