Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, and specifically relates to an electrical connector mating structure. Background Technology

[0002] Electrical connectors are fundamental components in electronic devices such as computers and televisions, and their applications are very wide and their role is very important. Two mating electrical connectors are generally distinguished as male and female. The male and female connectors are connected to different cables, circuit boards, or different devices, and by mating the male and female connectors, the electrical connectors act as a bridge between different cables, circuit boards, or different devices.

[0003] For most existing electrical connectors, the mating of male and female connectors is basically achieved by inserting metal terminals into the slots. Due to the insertion and removal of metal terminals into the slots, the metal terminals may become loose when inserted into the slots, resulting in poor contact between the metal terminals and the slots. At the same time, the existing anti-loosening mating structure of electrical connectors cannot simultaneously meet the requirements of angled insertion and flat insertion.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical connector mating structure that can solve the problem of poor contact caused by loosening between the metal terminal and the slot, as well as the problem that the anti-loosening mating structure cannot simultaneously meet the requirements of oblique insertion and flat insertion.

[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0007] An electrical connector mating structure includes:

[0008] The body assembly includes a housing, the ends of which are fitted with a plurality of metal terminals for insertion into slots to enable mating of male and female connectors.

[0009] The fastening assembly includes limiting rods, which are movably mounted on the two side walls of a narrow metal terminal. Multiple limiting rods are provided on each side wall of the narrow metal terminal, ensuring that the limiting rods contact the slot when the metal terminal is inserted into it. Multiple movable slots are formed on each side wall of the narrow metal terminal, and the limiting rods are slidably mounted within these slots. These slots allow the limiting rods to move while mounted on the side walls of the narrow metal terminal. One end of each limiting rod is positioned inside the metal terminal through a movable slot, while the other end is positioned outside the metal terminal, with the outer end contacting the slot. A compression spring is installed inside the movable slot. When the limiting rod contacts the slot, it retracts into the movable slot, compressing the compression spring. This causes the compression spring to exert a pushing force on the limiting rod outward from the metal terminal, resulting in one end of the limiting rod abutting against the inner wall of the slot. Through the abutment between multiple limiting rods and the inner wall of the slot, it is ensured that the metal terminal is continuously secured when inserted into the slot, thus ensuring good contact between the metal terminal and the slot and preventing poor contact during use.

[0010] In one or more embodiments of this utility model, a base plate is provided at the end of the housing away from the metal terminal, and the metal terminal and the base plate are connected in a detachable manner.

[0011] In one or more embodiments of this utility model, the housing is provided with a plurality of positioning holes, and a plurality of fixing pieces are integrally formed on the housing.

[0012] In one or more embodiments of this utility model, multiple limiting rods on the narrow side walls of the metal terminal are arranged in an interleaved manner, so that when the limiting rods are inserted into the slot, the multiple limiting rods can act on different positions of the inner side wall of the slot to ensure that the metal terminal is securely fastened to the slot after insertion.

[0013] In one or more embodiments of this utility model, the compression spring is sleeved onto the side wall of the limiting rod located within the movable groove, so that the compression spring can be compressed when the limiting rod moves, ensuring that the compression spring exerts an outward pushing force on the limiting rod. A limiting plate is fixedly connected to the side wall of the limiting rod located within the movable groove, and the outer diameter of the limiting plate matches the inner diameter of the movable groove, so that the limiting plate can not only restrict the limiting rod from sliding out of the movable groove, but also stabilize the limiting rod when sliding within the movable groove.

[0014] In one or more embodiments of this utility model, one end of the compression spring is fixedly connected to the movable groove, and the other end of the compression spring is fixedly connected to the limiting plate, so that after the compression spring is installed, the sliding of the limiting rod drives the limiting plate to slide, thereby the compression spring can be compressed through the limiting plate.

[0015] In one or more embodiments of this utility model, a limiting ring is fixedly connected to the inner sidewall of the outer end of the movable groove. The limiting plate and the limiting ring cooperate to prevent the limiting rod from sliding out of the movable groove. The inner diameter of the limiting ring matches the outer diameter of the limiting rod, allowing the limiting rod to slide through the limiting ring.

[0016] In one or more embodiments of this utility model, the limiting rod has a wedge-shaped portion at one end outside the metal terminal. When the metal terminal is inserted, if the wedge-shaped portion contacts the slot, the moving metal terminal will push the limiting rod back into the movable slot under the action of the wedge-shaped portion. This ensures that the limiting rod does not affect the normal installation between the metal terminal and the slot while maintaining their tightness. The end of the limiting rod outside the metal terminal has a frosted layer, which contacts the inner wall of the slot. The friction between the frosted layer and the inner wall of the slot further ensures the tightness between the metal terminal and the slot.

[0017] In one or more embodiments of this utility model, both the limiting rod and the limiting plate are made of conductive metal material, so that the limiting rod can not only secure the metal terminal to the slot but also conduct electricity, ensuring that there is no poor contact between the metal terminal and the slot.

[0018] In one or more embodiments of this utility model, a fixing hole is provided on the metal terminal, which allows the metal terminal to be stably inserted into the slot. A magnetic layer is provided on the inner sidewall of the fixing hole, which can further improve the stability of the metal terminal after installation.

[0019] Compared with the prior art, this utility model provides multiple fastening components on the narrow side walls of the metal terminal. When the metal terminal is inserted into the slot, the action between the fastening components and the slot ensures that the metal terminal and the slot remain in a fastened state, thus ensuring good contact between the metal terminal and the slot. At the same time, the fastening components are suitable for both oblique and horizontal insertion, which can meet the requirements of both oblique and horizontal insertion at the same time.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an electrical connector mating structure, which includes a body assembly 1 and a fastening assembly 2.

[0030] like Figure 1 and Figure 2 As shown, the main body assembly 1 includes a housing 11, and a plurality of metal terminals 12 are installed at the end of the housing 11. The plurality of metal terminals 12 are used to be inserted into the slot to realize the mating of the male and female connectors.

[0031] like Figure 1 and Figure 2 As shown, a base plate 13 is provided at the end of the housing 11 away from the metal terminal 12, and the metal terminal 12 and the base plate 13 are connected in a detachable manner.

[0032] like Figure 1 and Figure 2 As shown, the housing 11 has multiple positioning holes 14 and multiple fixing pieces 15 integrally formed on the housing 11.

[0033] like Figures 3-5 As shown, the fastening assembly 2 includes limiting rods 21, which are movably mounted on the two side walls of the narrow side of the metal terminal 12. Multiple limiting rods 21 are provided on each side wall of the narrow side of the metal terminal 12, ensuring that the limiting rods 21 can contact the slot when the metal terminal 12 is inserted into it. Multiple movable slots 22 are provided on each side wall of the narrow side of the metal terminal 12, and the limiting rods 21 are slidably mounted within these slots. The movable slots 22 allow the limiting rods 21 to move while mounted on the side wall of the narrow side of the metal terminal 12. One end of the limiting rod 21 is placed inside the metal terminal 12 through the movable slot 22, and the other end is placed outside the metal terminal 12, with the outer end contacting the slot. A compression spring 23 is installed inside the movable slot 22. When the limiting rod 21 contacts the slot, it retracts into the movable slot 22, compressing the compression spring 23. This causes the compression spring 23 to exert a pushing force on the limiting rod 21 towards the metal terminal 12, resulting in one end of the limiting rod 21 abutting against the inner wall of the slot. Through the abutment between multiple limiting rods 21 and the inner wall of the slot, it is ensured that the metal terminal 12 is continuously secured when inserted into the slot, thus ensuring good contact between the metal terminal 12 and the slot and preventing poor contact during use.

[0034] like Figure 4 As shown, multiple limiting rods 21 on the narrow side walls of the metal terminal 12 are arranged in an interleaved manner, so that when the limiting rods 21 are inserted into the slot, the multiple limiting rods 21 can act on different positions of the inner side wall of the slot, ensuring that the metal terminal 12 is securely fastened to the slot after insertion.

[0035] like Figure 4 Combination Figure 5As shown, the compression spring 23 is sleeved onto the side wall of the limiting rod 21 located within the movable groove 22, so that the compression spring 23 can be compressed when the limiting rod 21 moves, ensuring that the compression spring 23 exerts an outward pushing force on the limiting rod 21. A limiting plate 25 is fixedly connected to the side wall of the limiting rod 21 located within the movable groove 22. The outer diameter of the limiting plate 25 matches the inner diameter of the movable groove 22, so that the limiting plate 25 can not only restrict the limiting rod 21 from sliding out of the movable groove 22, but also stabilize the limiting rod 21 when it slides within the movable groove 22.

[0036] like Figure 4 Combination Figure 5 As shown, one end of the compression spring 23 is fixedly connected to the movable groove 22, and the other end of the compression spring 23 is fixedly connected to the limiting plate 25. After the compression spring 23 is installed, the sliding of the limiting rod 21 drives the limiting plate 25 to slide, so that the compression spring 23 can be compressed through the limiting plate 25.

[0037] like Figure 4 Combination Figure 5 As shown, a limiting ring 26 is fixedly connected to the inner wall of the outer end of the movable groove 22. The limiting plate 25 and the limiting ring 26 cooperate to prevent the limiting rod 21 from sliding out of the movable groove 22. The inner diameter of the limiting ring 26 matches the outer diameter of the limiting rod 21, allowing the limiting rod 21 to slide through the limiting ring 26.

[0038] like Figures 3-5 As shown, the limiting rod 21 has a wedge-shaped portion 24 at one end outside the metal terminal 12. When the metal terminal 12 is inserted, when the wedge-shaped portion 24 contacts the slot, the limiting rod 21 can be pushed back into the movable slot 22 by the action of the wedge-shaped portion 24 as the metal terminal 12 moves. This ensures that the limiting rod 21 does not affect the normal installation between the metal terminal 12 and the slot while ensuring their tightness. The end of the limiting rod 21 outside the metal terminal 12 has a frosted layer 29. The end of the limiting rod 21 with the frosted layer 29 contacts the inner wall of the slot. The friction between the frosted layer 29 and the inner wall of the slot further ensures the tightness between the metal terminal 12 and the slot.

[0039] Preferably, both the limiting rod 21 and the limiting plate 25 are made of conductive metal material, so that the limiting rod 21 can not only secure the metal terminal 12 to the slot, but also conduct electricity, ensuring that there is no poor contact between the metal terminal 12 and the slot.

[0040] like Figure 1 and Figure 2As shown, a fixing hole 27 is provided on the metal terminal 12, which allows the metal terminal 12 to be stably inserted into the slot. A magnetic layer 28 is provided on the inner side wall of the fixing hole 27, which can further improve the stability of the metal terminal 12 after installation.

[0041] It should be noted that the technical improvements in this application only involve structural improvements and do not involve any circuit improvements. Therefore, all wiring of the electrical connector is prior art.

[0042] Furthermore, the fastening component 2 provided in this application is suitable for both flat and angled insertion, and can be adjusted according to whether the electrical connector is angled or flat, thus meeting the requirements of both types of electrical connectors simultaneously.

[0043] When using the electrical connector, the male and female connectors need to be mated by inserting multiple metal terminals 12 on the male connector into the corresponding slots on the female connector. During insertion, when the limiting rod 21 on the metal terminal 12 contacts the slot wall, the wedge-shaped part 24 will push the movable groove 22 back into the movable groove 22. The limiting rod 21 will compress the compression spring 23, so that the compression spring 23 has an outward pushing force on the limiting rod 21. When the metal terminal 12 is fully inserted into the slot, one end of the multiple limiting rods 21 will abut against the inner wall of the slot under the action of the compression spring 23, so that the metal terminal 12 and the slot are always in a tight state, ensuring that there is no poor contact between the male and female connectors.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
