Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector anti-wrong insertion structure. Background Art

[0002] Electrical connectors are used to connect two active devices to transmit current or signals. In the interconnection of electronic circuits, multiple connectors of the same specification are often installed on the same panel or PCB. The electrical connector can only operate after the plug and socket are correctly matched and plugged. The structure or mechanism that enables the electrical connector plug and socket to be correctly matched and plugged is generally called an anti-misplugging mechanism. In order to prevent misplugging between connectors, the connector is usually required to have an anti-misplugging function.

[0003] Therefore, a connector that prevents wrong insertion has appeared on the market. The use of bosses and grooves to prevent wrong insertion can also be used to fix the connection between the plug and the socket due to the unstable connection of small connectors. However, it is found that the fixing method of fixing the boss into the groove to prevent the plug from falling off is difficult to pull out and it is easy to damage the pin or socket when excessive force is applied. There is an urgent need for a structure that can prevent wrong insertion, play a positioning role, and pull out without damaging the connector. Utility Model Content

[0004] In order to solve the problems of the prior art, the utility model provides a connector anti-misinsertion structure; it aims to provide a connector anti-misinsertion structure that can prevent misinsertion and can fix the male and female ends and make them easy to pull out without damaging the connector.

[0006] By adopting the above technical scheme, the utility model can ensure correct insertion by arranging the anti-mistake groove and the anti-mistake protrusion at the upper or lower part of the connecting end surface of the male and female connectors, while the positioning member and the positioning groove can ensure the stable position of the connector, improve the connection reliability, and the positioning member can be unfixed by the control component.

[0007] Furthermore, the fool-proofing protrusion is a hollow structure with an active cavity provided therein, the positioning member includes a displacement portion which can be laterally displaced in the active cavity and a snap portion provided at the head end of the positioning member, and the head end of the fool-proofing protrusion is provided with a matching active hole.

[0008] By adopting the above technical solution, the positioning member is displaced in the movable cavity to retract the buckle portion from the movable hole into the movable cavity, and the male connector can be easily pulled out without damaging the connector by disengaging from the positioning hole.

[0009] Furthermore, the control component includes a displacement cavity provided on both sides of the male end insulating portion and a pressing member integrally formed with the rear end of the positioning member and capable of displacement in the displacement cavity.

[0010] By adopting the above technical solution, the displacement part of the positioning member can be driven to move by pressing the pressing members on both sides of the insulating part of the male end.

[0011] Furthermore, an elastic member is provided in the displacement cavity, and the elastic member and the pressing member abut against each other.

[0012] By adopting the above technical solution, the pressing member abuts against the elastic member after pressing to perform lateral displacement in the displacement cavity, and the pressing member can be reset by releasing it, thereby driving the positioning member to reset for next use.

[0013] Furthermore, the elastic member is a low-carbon steel compression spring.

[0014] By adopting the above technical solution, the low carbon steel compression spring has good elasticity and reset performance. It can maintain its original shape and elasticity after multiple compressions and releases, which can ensure the long-term stability and durability of the control component.

[0015] Furthermore, guide arrows are provided on both the male connector and the female connector.

[0016] By adopting the above technical solution, the correct insertion direction can be prompted under naked eye observation to avoid misplaced insertion, which can help users find the correct insertion direction more quickly and reduce operational troubles caused by reverse insertion, thereby improving the convenience of connector use and saving time and energy.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0028] like Figures 1 to 3 As shown, a connector anti-misplugging structure can provide a connector anti-misplugging structure that can prevent misplugging and can make the male and female ends fixed and easy to pull out without damaging the connector. The structure is arranged between a male connector 1 and a female connector 2 that are plugged into and fit with each other. The male connector 1 includes a male connecting part 11 and a male insulating part 12 wrapped around the tail end of the male connecting part 11. The female connector 2 includes a female jack 21 for inserting the male connecting part 11. The connector anti-misplugging structure of this embodiment includes anti-misplugging protrusions 3 arranged on both sides of the male connecting part 11 at a position deviating from the middle position and anti-misplugging grooves 4 arranged on both sides of the above-mentioned female jack 21 corresponding to the anti-misplugging protrusions 3. A positioning piece 5 is provided at the tail end of the anti-misplugging protrusion 3. A positioning hole 6 adapted to the positioning piece 5 is provided at the tail end of the anti-misplugging groove 4. A control component 7 for controlling the elastic displacement of the positioning piece 5 is also provided on the male connector 1.

[0029] In this embodiment, by setting the anti-idiocy groove 4 and the anti-idiocy protrusion 3 at the upper or lower part of the connection end surface of the male and female connectors 2, the anti-idiocy protrusion 3 cannot be inserted into the anti-idiocy groove 4 when the male connector 1 is inserted upside down, so that it has an anti-plugging effect, ensures correct plugging, avoids wrong insertion, prevents misoperation and damage to the connector, and improves the overall stability and reliability. The design of the positioning member 5 and the positioning hole 6 allows the position of the connector to be stably fixed. It can help the reliability of the connector under vibration, impact and other external forces. Ensure that the connector will not accidentally disengage or loosen, and maintain a good connection state. Through the control component 7, the positioning member 5 can be unfixed, and the male connector 1 can be easily pulled out without damaging the connector, thereby improving the maintainability and operability of the system.

[0030] like Figure 2 and Figure 3As shown, the foolproof protrusion 3 of this embodiment is a hollow structure and is provided with an active cavity 31, and the positioning member 5 includes a displacement portion 51 disposed in the active cavity 31 and capable of lateral displacement, and a buckle portion 52 disposed at the head end of the positioning member 5, and an active hole 32 of a matching shape and size is also provided at the head end of the foolproof protrusion. The positioning member 5 is displaced in the active cavity 31 so that the displacement portion 51 retracts the buckle portion 52 into the active cavity 31, and the buckle portion 52 is disengaged from the positioning hole 6. This allows the user to easily pull out the male connector 1 without damaging the connector or causing a connection failure, and the operation is simple, fast and reliable.

[0031] like Figure 2 As shown, the control component 7 of this embodiment specifically includes a displacement cavity 71 arranged on both sides of the male end insulating part 12 and a pressing piece 72 which is integrally formed with the tail end of the positioning member 5 and can be displaced in the displacement cavity 71. By pressing the pressing pieces 72 on both sides of the male end insulating part 12, the displacement part 51 of the positioning member 5 can be driven to displace. And an elastic piece 73 is provided in the displacement cavity 71, and the elastic piece 73 and the pressing piece 72 abut against each other. After the pressing piece 72 is pressed, it abuts against the elastic piece 73 to displace laterally in the displacement cavity 71. The pressing piece 72 can be reset by releasing it, thereby driving the positioning member 5 to reset for the next use. Specifically, this elastic piece 73 is a low-carbon steel compression spring, which has good elasticity and reset performance. It can maintain its original shape and elasticity after multiple compressions and releases, which can ensure the long-term stability and durability of the control component 7.

[0032] like Figure 1 As shown, guide arrows 8 are provided on both the male connector 1 and the female connector 2. By providing the guide arrows 8, the correct insertion direction can be indicated under naked eye observation, and misplaced insertion can be avoided, which can help users find the correct insertion direction more quickly and reduce operational troubles caused by reverse insertion, thereby improving the convenience of using the connector and saving time and energy.

[0033] The working principle of this embodiment is as follows: This embodiment ensures correct plugging and avoids wrong insertion by setting foolproof grooves 4 and foolproof protrusions 3 deviating from the middle position on both sides of the plug-in end faces of the male and female connectors 2. Then, the position of the connector is ensured to be stable through the cooperation of the positioning member 5 and the positioning hole 6. Then, a displacement cavity 71 is provided in the foolproof protrusion 3, and a pressing member 72 that can control the displacement of the positioning member 5 is provided to cancel the positioning member 5 and easily pull out the male connector 1 without damaging the connector.

[0034] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
