Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and specifically to a novel connector. Background Technology
[0002] Connectors, especially aviation connectors, have a joint consisting of a thin cap, a seal, a thick cap, a conductive element, and a metal sleeve. The seal is located between the thin and thick caps. One end of the conductive element passes through the thin cap and the seal, extending into the thick cap. The front end of the thick cap is used to connect with an external connector, while the other end of the conductive element forms an electrical connection with an external cable. The metal sleeve is fitted over the thin cap, seal, and thick cap to create a secure fit.
[0003] However, in actual installation, the seal serves a sealing function (the connection between the seal and the conductive component is an interference fit). Typically, the conductive component is first fitted to the thick cap, then the conductive component extends through the seal into the thick cap, and finally the thin cap is fitted to the conductive component. The problem with this installation method is that the seal is prone to displacement (the seal may lift) during the installation of the conductive component. The operator needs to completely adhere the seal to the thick cap before continuing to install the conductive component, affecting processing efficiency. Those skilled in the art have also used adhesive to bond the seal to the thick cap, but this method adds the step of applying adhesive. Others have used potting adhesive to form the seal, but this method is prone to adhesive overflow at the front end of the thick cap during potting, requiring the operator to handle the overflow, which also reduces processing efficiency. Utility Model Content
[0004] Therefore, the technical problem to be solved by this utility model is how to improve the fixing structure between the sealing element and the thick cover. To this end, a novel connector includes a body, the body having a connector end, the connector end including a thin cover, a sealing element, a thick cover, a conductive element, and a metal sleeve.
[0005] The thick cover has an annular groove, and the sealing element has a fixing part, which is embedded in the annular groove; in the first state, the thick cover is formed by the mold; in the second state, the thick cover with the sealing element fixed is formed by the mold.
[0006] The annular groove is dovetail-shaped.
[0007] The thick cover has a first through hole, the sealing element has a second through hole, and the thin cover has a third through hole. The inner diameter of the second through hole is smaller than that of the first through hole and the third through hole.

[0015] 2. This utility model provides a novel connector with a dovetail design, which further improves the connection strength between the seal and the thick cover, preventing separation of the seal and the thick cover due to strong pulling.

[0016] 3. The novel connector provided by this utility model has a second through hole that creates an interference fit, enabling the seal to achieve a better seal.
[0017] 4. The present invention provides a novel connector that uses a limiting part to create a limiting effect, thereby defining the position of the conductive component.

[0035] Example 1
[0036] This embodiment provides a novel connector, as shown in the attached figure. Figures 1-6 As shown, it includes:
[0037] The body 11 has a connector end 111, which includes a thin cover 12, a sealing element 13, a thick cover 14, a conductive element 15, and a metal sleeve 16. The metal sleeve 16 has a chamber 161, in which the thin cover 12, the sealing element 13, and the thick cover 14 are housed. One end of the conductive element 15 passes through the thin cover 12 and the sealing element 13 and extends into the thick cover 14. The other end of the conductive element 15 is used for connection with a cable. The front end of the thick cover 14 mates with an external connector, which is inserted into the thick cover 14 to form an electrical connection with the conductive element 15. The thick cover 14 has an annular groove 141, and the sealing element 13 has a fixing part 131. The annular groove 141 and the fixing part 131 are located at the connection between the thick cover 14 and the sealing element 13. That is, the annular groove 141 is located at the rear end of the thick cover 14, and the fixing part 131 is located at the front end of the sealing element 13. The fixing part 131 is embedded in the annular groove, thereby achieving the mating between the two.
[0038] In the first state, the thick cover 14 is formed by mold processing. Specifically, this mold processing involves injection molding within the mold. The first fixed mold and the moving mold cooperate to form a cavity identical to the thick cover 14, thus achieving the processing of the thick cover 14. In the second state, the thick cover 14 with the sealing element 13 is fixed in place by mold processing. This mold processing specifically refers to secondary processing. The processed thick cover 14 and the moving mold rotate together to the next processing station. At this time, the second fixed mold and the moving mold cooperate to form another cavity. The thick cover 14 is located in this cavity, and the mold performs a glue-filling process. The glue is then molded to form the sealing element 13. The fixing part 131 is formed by the glue flowing into the annular groove 141 and cooling to solidify, thus firmly fixing the thick cover 14 and the sealing element 13. The principle is the same as the secondary injection molding process. In this embodiment, the thick cover 14 is made of plastic, and the sealing element 13 is made of rubber. The strength of the sealing element 13 is lower than that of the thick cover 14. The thick cover 14 is formed through a single process, and the sealing element 13 is formed through a second process. This allows the sealed element 13 to be directly connected and fixed to the thick cover 14. The connection is secured by the cooperation of the fixing part 131 and the annular groove 141. During the installation of the conductive component 15, the sealing element 13 will not detach, improving installation efficiency. This processing method is equivalent to a mold set consisting of a first fixed mold, a second fixed mold, and two moving molds.
[0039] Specifically, as shown in the attached document Figures 2-3As shown, the annular groove 141 is dovetail-shaped. Specifically, the dovetail shape means that the bottom dimension of the annular groove 141 is larger than the dimension of the opening of the annular groove, forming a dovetail shape. This dovetail design further enhances the connection strength between the seal 13 and the thick cover 14, preventing separation between them due to excessive pulling. Alternatively, other structures can be used, such as ribs or textures on the inner wall of the annular groove 141, allowing the seal 13 to form an embedded effect during potting and molding, thus improving the fixing strength.
[0040] Specifically, as shown in the attached document Figures 1-5 As shown, the thick cover 14 has a first through hole 142. The number of first through holes 142 can be adjusted according to actual needs. In this embodiment, the number of first through holes 142 is the same as the number of conductive elements 15. The sealing element 13 has a second through hole 132, and the number of second through holes 132 is the same as the number of conductive elements 15. The thin cover 12 has a third through hole 121, and the number of third through holes 121 is the same as the number of conductive elements 15. In this embodiment, the first through hole 142, the second through hole 132, and the third through hole 121 are coaxially arranged. The inner diameter of the second through hole 132 is smaller than that of the first through hole 142 and the third through hole 121. The arrangement of the second through hole 132 forms an interference fit effect, allowing the sealing element 13 to achieve a better seal. The conductive element 15 extends through the third through hole 121 and the second through hole 132 into the first through hole 142.
[0041] Specifically, as shown in the attached document Figure 3 , Figure 6 As shown, a limiting part 122 is provided on the inner wall of the third through hole 121, and the limiting part 122 cooperates with the conductive element 15. The limiting part 122 forms a limiting effect, thus defining the position of the conductive element 15. The limiting part 122 and the conductive element 15 form a foolproof effect.
[0042] Specifically, as shown in the attached document Figures 3-6 As shown, the thick cover 14 is provided with a first positioning rib 143, the sealing element 13 is provided with a second positioning rib 133, and the thin cover 12 is provided with a third positioning rib 123. The second positioning rib 133 connects the first positioning rib 143 and the third positioning rib 123, and the second positioning rib 133, the first positioning rib 143, and the third positioning rib 123 are all located in the same direction. The inner wall of the metal sleeve 16 is provided with a positioning groove 162, that is, the inner wall of the chamber 161 is provided with a positioning groove 162. Through the cooperation of the positioning rib and the positioning groove 162, a positioning and fixing effect is formed, and it also has a foolproof effect.
[0043] Specifically, as shown in the attached document Figures 1-3As shown, the connector end 111 also includes a retaining spring 17. The inner wall of the metal sleeve 16 has a retaining groove 163, and a portion of the retaining spring 17 extends into the retaining groove 163, abutting against the thin cover 12. The retaining spring 17, in conjunction with the retaining groove 163, secures the thin cover 12, preventing it from shaking. In this embodiment, the retaining spring 17 abuts against the rear end of the thin cover 12 to achieve the securing effect.
[0044] Specifically, as shown in the attached document Figures 1-6 As shown, the thick cover 14 has a stepped protrusion 144, and the inner wall of the metal sleeve 16 has a stepped groove 164 that mates with the stepped protrusion 144. The engagement of the stepped protrusion 144 and the stepped groove 164 prevents the thick cover 14 from extending from the front end of the metal sleeve 16, thus creating a limiting and fixing effect.
[0045] Specifically, as shown in the attached document Figure 6 As shown, the metal sleeve 16 also has a through groove 165 on its sidewall, which extends to the front end of the metal sleeve 16. The through groove 165 provides a certain degree of elasticity when mating with an external connector, reducing the difficulty of insertion and removal.
[0046] Specifically, the front end of the thick cover 14 does not extend beyond the front end of the metal sleeve 16.
[0047] Specifically, in addition to the waterproof seal between the connector ends 111, the body 11 also has waterproof designs at the bends and connections with the cable, improving the overall sealing level of the connector.
[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
