Description

Technical Field

[0001] This utility model relates to electrical connectors, specifically to an electrical connector with a self-locking mechanism. Background Technology

[0002] Currently available connectors mostly use threaded locking or rotary locking methods. During connection, manual or tool-assisted rotation of related components is required to achieve locking, resulting in slow installation efficiency. Furthermore, in confined spaces, it's difficult to use tools for rotational tightening, limiting application environments. These locking methods also carry the risk of loosening; in vibration environments, the rotating components can easily loosen and disengage, leading to poor contact and product failure. In terms of manufacturing, existing connectors require pre-installing the waterproof rubber ring and rotating components onto the rubber core before injection molding a cylindrical sheath. This process is prone to problems such as the waterproof rubber ring detaching during production.

[0003] Therefore, it is necessary to improve the existing electrical connectors. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0041] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0042] Example 1: The specific structure of this utility model is as follows:

[0043] Please refer to the appendix. Figures 1-9 The present invention provides an electrical connector with a self-locking mechanism, comprising a female plug 100 and a male plug 200. The female plug 100 includes a female end body 11. After the female end body 11 and the male plug 200 are connected by mating, they are locked and fixed by a self-locking mechanism.

[0044] The self-locking mechanism includes:

[0045] A locking ring 1 is rotatably mounted on the socket end of the female body 11, and the inner wall of the locking ring 1 is provided with a plurality of first buckles;

[0046] A reset member disposed between the locking ring 1 and the female end body 11, which enables the locking ring 1 to be reset in the rotational direction;

[0047] Multiple second latches are provided on the outer wall of the male plug 200. The second latches are set one-to-one with the first latches. The second latches enter the locking ring 1 by being misaligned with the first latches. After the locking ring 1 is reset, the first latches and the second latches are interlocked.

[0048] The reset component is a compression spring 3.

[0049] The female end body includes a first rubber core 4, which has multiple pin holes penetrating both ends. Its outer wall is provided with a mounting groove in the circumference. The mounting groove is divided into a spring receiving groove 15 and a limiting slide groove 20. The compression spring 3 is provided with the spring receiving groove 15.

[0050] The spring receiving groove 15 has opposing spring locking points 14 on its opposite sidewalls near the blocking end. The two opposing spring locking points 14 are used to fix one end of the compression spring 3.

[0051] The inner wall of the locking ring 1 is provided with a first protrusion 24 for fixing the other end of the compression spring 3.

[0052] The inner wall of the locking ring 1 is also provided with a plurality of second protrusions 25. The second protrusions 25 and the first protrusions 24 are in the same circumference and are both located at the inner edge of the inner opening of the locking ring 1.

[0053] The mounting slot is also provided with a notch 17 for the first protrusion 24 and the second protrusion 25 to enter the slot.

[0054] The main body 11 of the female end also includes a waterproof rubber ring 2, a conductive pin 5 and a rubber-coated model 6; the conductive pin 5 is welded and fixed one-to-one with the wire core on the female end conductor 7, and there are three conductive pins 5, namely the L line, the N line and the ground line.

[0055] The waterproof rubber ring 2 is fitted onto the step of the socket end of the first rubber core 4. When the male plug 200 is inserted into the female plug 100, the waterproof rubber ring 2 can achieve the purpose of waterproofing.

[0056] The first core 4 has a plurality of fan-shaped posts 16 that are disconnected and equally distributed at the socket end, with gaps between the plurality of fan-shaped posts 16. One side corner of one of the fan-shaped posts is provided with a non-foolproof groove 19. The pin hole is located in the fan-shaped post 16, and the conductive pin 5 passes through and is fixed in the pin hole.

[0057] The first rubber core 4 and the rubber-coated model 6 are threaded together.

[0058] The plurality of first buckles are triangular teeth 22, which are circumferentially distributed at equal angles and located on the inner edge of the outer opening of the locking ring 1, with the hypotenuses of the triangular teeth 22 facing outward.

[0059] The male plug 200 includes a second core 34, the insertion end of which is provided with a slot 38 for the triangular retaining teeth 22 to enter, the slot 38 being the second latching part. Hook-shaped retaining blocks 36 are formed between each slot 38, the slot 38 having an L-shaped structure and a guide slope 37 at its inlet end.

[0060] The second core 34 has multiple partitioned cavities at its insertion end, which are divided equally by multiple partition plates 33. One of the partition plates 33 has a foolproof post 35. There are three partitioned cavities, which divide a circle into three equal fan-shaped cavities. The partitioned cavities can separate each conductive pin 5 and conductive pin sleeve, effectively preventing mutual interference. The cooperation between the foolproof groove 19 and the foolproof post 35 can effectively prevent accidental insertion. The grounding conductive pin is lengthened, and the connection is made by first making the connection open and then closing it, which can provide a good protective grounding effect.

[0061] The male plug 200 also includes multiple conductive pin sleeves, which are arranged one-to-one in the multiple partition cavities. Three conductive pin sleeves are provided, each corresponding to one of the three conductive pins 5. The three conductive pin sleeves are soldered one-to-one to the three wire cores on the male end conductor 28. After the male plug 200 and female plug 100 are inserted, the three conductive pins 5 are inserted into the corresponding three conductive pin sleeves to achieve electrical conductivity.

[0062] Example 2:

[0063] When the male plug 200 and female plug 100 are connected, the triangular locking teeth 22 on the locking ring 1 rotate under force, which in turn compresses the spring 3. When the connectors are fully inserted, the triangular locking teeth 22 on the locking ring 1 loses their locking restraint, and under the elastic force of the spring 3, the locking ring automatically rotates back to its original position. In this position, the L-shaped groove on the second rubber core 34 blocks the triangular locking teeth 22 on the locking ring 1, preventing it from moving in the pull-out direction, thus achieving a self-locking effect.

[0064] When the connector needs to be removed, simply rotate the locking ring 1 in the direction indicated by the arrow to move the triangular locking teeth 22 to a position where there is no locking restraint, and then pull it out to achieve disassembly. This quick self-locking connection method requires no tools and no space for tool operation, which not only greatly improves the user's assembly and connection efficiency, but also meets the requirements for use in various confined spaces. Furthermore, after locking, the locking ring 1 is always subject to the elastic force of the compression spring 3, ensuring that the locking ring 1 is in a stable position, thereby ensuring that the product always maintains a stable connection state and guarantees the product's stability, reliability, and safety.

[0065] In addition, the locking ring 1 is equipped with four triangular locking teeth 22. The four triangular locking teeth 22 are evenly distributed, which can not only effectively decompose the pulling force on the cable and improve the tensile strength of the product, but also cooperate and restrain each other when the pulling force direction is deviated, so that the offset space of the overall connector is small, thereby avoiding large offset between the conductive pin 5 and the conductive pin sleeve, avoiding poor contact, and ensuring the stability and reliability of the electrical signal connection.

[0066] In summary, the electrical connector of this utility model achieves a self-locking function, eliminating the need for manual or tool-assisted rotation of the components; locking can be completed simply by inserting the male and female plugs together, greatly improving installation efficiency, and is especially suitable for confined spaces.

[0067] The reset component (compression spring 3) of this utility model provides a stable reset force, ensuring that the first and second latches are tightly interlocked, and is not easy to loosen under vibration environment, thus avoiding product failure due to poor contact.

[0068] The main body of this utility model adopts a structure in which the first rubber core is threadedly connected to the rubber-coated model. During production, the rubber-coated model can be injection molded first, and then accessories such as waterproof rubber rings can be assembled, reducing the risk of waterproof rubber rings falling off and optimizing the production process.

[0069] This utility model features a foolproof groove and a foolproof post that work together to ensure correct insertion of the male and female plugs and prevent damage to components caused by misinsertion. The triangular teeth of the locking ring cooperate with the L-shaped groove and guide bevel of the male plug, ensuring smooth insertion and high locking reliability.

[0070] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
