Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to the connection structure of an elliptical inner core connector. Background Technology
[0002] In some regions or certain models of electrical appliances, the special terminals and their placement structure result in a non-rotating elliptical core inside the connector. In conventional designs, the male and female heads of this type of connector are usually fixed and tightened by a snap-fit mechanism. However, in applications, some snap-fit mechanisms are difficult to complete with one hand, making operation cumbersome. Moreover, after a period of use, the snap-fit mechanism is prone to loosening, which not only affects the stability of the connection but also the tightness of the internal waterproof components. This allows moisture and other foreign matter in the air to enter the connector, corroding the terminals and affecting the stability and transmission effect of electrical signals. Summary of the Invention
[0003] To address the problems existing in the prior art, this utility model provides a connection structure for an elliptical inner core connector. While rotating the male locking member to lock the male and female ends, the male body drives the male core to insert into the female core, completing the locking and fixing of the male and female ends and the conductive connection between the male and female terminals. Simultaneously, it can effectively shield external interference signals. After the male and female ends are inserted into place, they can press against the male body and seal their ends. In conjunction with the outer sealing ring, it can achieve waterproof sealing of the inner and outer walls of the male and female ends, effectively protecting the internal male and female terminals and grounding terminals of the connector, ensuring the stability and efficiency of signal transmission.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] The connection structure of the elliptical inner core connector includes independent and mating male and female terminals, wherein the mating ends of the inner cores of both the male and female terminals are elliptical in structure; wherein:
[0006] The male end includes an annular male end body, a male end core is sleeved inside the male end body, two or more male terminals are embedded in the male end core, and an elliptical male end guide groove is formed around the periphery of a plurality of male terminals at the end of the male end body facing the female end. The male end body is sleeved with a male end locking member that can slide with it in the circumferential direction.
[0007] The female end includes a female end locking member that can be fitted and screwed onto the male end locking member. A female end rubber core is fitted inside the female end locking member. The end of the female end rubber core facing the male end has a protrusion that matches the male end guide groove. Several female terminals that can match the male terminals are embedded in the protrusion. An inner sealing ring and a clamping member are provided around the protrusion. One end of the clamping member is connected to a grounding terminal provided on the female end rubber core. When inserted, the male end locking member is screwed into the female end locking member, which can push the male end into the female end. The male end body squeezes the clamping member and the inner sealing ring to achieve radial clamping and axial sealing of the male end and the female end, and at the same time achieve grounding connection.
[0008] As a further explanation of the above technical solution:
[0009] In the above technical solution, the clamping member includes an elastic clamping part and a connecting part arranged along the axial direction. The connecting part is connected to the grounding terminal. The elastic clamping part has a C-shaped structure and is matched and surrounds the outer wall of the protrusion. Several cantilever arms extending toward the male end are formed thereon. Each cantilever arm can deform when the male end is inserted to press against the inner wall of the male end body.
[0010] In the above technical solution, each of the cantilever arms has an elastic portion that protrudes outward in the middle.
[0011] In the above technical solution, the protrusion has a square structure, and each of its outer walls has one or more of the aforementioned cantilever arms on its periphery.
[0012] In the above technical solution, the grounding terminal is arranged in parallel with a plurality of female terminals and all extend to the outer side of the end of the female end core away from the male terminal, and the female end core is provided with a female end guide groove that is adapted to each of them.
[0013] In the above technical solution, the outer wall of the male locking member and the inner wall of the female locking member are both formed with mutually matching threads.
[0014] In the above technical solution, the outer wall of the male end body is a stepped structure and has a sliding groove, a positioning ring is fitted in the sliding groove, and a slot matching the positioning ring is formed on the inner wall of the male end locking member.
[0015] In the above technical solution, the positioning ring has a C-shaped structure.
[0016] In the above technical solution, the cross-section of the positioning ring is square.
[0017] In the above technical solution, the outer wall of the female end locking member has a stepped structure and a positioning groove is formed. An outer sealing ring is embedded in the positioning groove. A locking nut is provided on the side of the outer sealing ring away from the male end. The locking nut is fitted onto the female end locking member and can press the outer sealing ring against the outer wall of the female end locking member.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: By providing a male locking member that slides circumferentially around the male end body, and providing a thread on the outer wall of the male locking member that matches the inner wall of the female locking member, the male locking member can be rotated to lock the male and female ends, while the male end body drives the male end core to insert into the female end core, thus completing the locking and fixing of the male and female ends and the conductive connection of the male and female terminals. At the same time, it can better shield external interference signals. By providing an inner sealing ring and a clamping member on the female end core, after the male and female ends are inserted into place, the rebound force of the clamping member can press against the male end body and seal its end. In cooperation with the outer sealing ring on the outer wall of the female locking member, the inner and outer walls of the male and female ends can be sealed and waterproofed, effectively protecting the male and female terminals and grounding terminals inside the connector, and ensuring the stability and efficiency of signal transmission.

A male end locking member 40 that can slide circumferentially connected to the male end body 10 is sleeved on the male end body 10.
[0030] like Figure 3-4 As shown, in one embodiment of the present invention, the outer wall of the male end body 10 is a stepped structure and has a groove 11. A positioning ring 3 is fitted into the groove 11. A slot 41 matching the positioning ring 3 is formed on the inner wall of the male end locking member 40. The positioning ring 3 has a C-shaped structure and a square cross-section.
[0031] like Figure 5 As shown, the female end 200 includes a female end locking member 50 that can be fitted and screwed onto the male end locking member 40. A female end rubber core 60 is fitted inside the female end locking member 50. The end of the female end rubber core 60 facing the male end 100 is provided with a protrusion 61 that is adapted to the male end guide groove 12. A plurality of female terminals 70 that can be adapted to the male terminals 30 are embedded in the protrusion 61. An inner sealing ring 1 and a clamping member 80 are provided around the protrusion 61. One end of the clamping member 80 is connected to the grounding terminal 90 provided on the female end rubber core 60. When inserted, the male end locking member 40 is screwed into the female end locking member 50, which can push the male end 100 into the female end 200 and cause the male end body 10 to squeeze the clamping member 80 and the inner sealing ring 1 to achieve radial clamping and axial sealing of the male end 100 and the female end 200. In this embodiment, the outer wall of the male locking member 40 and the inner wall of the female locking member 50 are both formed with mutually matching threads 2. The grounding terminal 90 and the clamping member 80 are integrally formed. The grounding terminal 90 and several female terminals 70 are arranged in parallel and all extend to the outer side of the end of the female core 60 away from the male end 100. The female core 60 is provided with a female guide groove 62 that is adapted to it.
[0032] like Figure 2 As shown, in one embodiment of this utility model, the outer wall of the female end locking member 50 is a stepped structure and has a positioning groove 51. An outer sealing ring 4 is embedded in the positioning groove 51. A locking nut 5 is provided on the side of the outer sealing ring 4 away from the male end 100. The locking nut 5 is fitted onto the female end locking member 50 and can press the outer sealing ring 4 against the outer wall of the female end locking member 50.
[0033] like Figure 6As shown, in one embodiment of the present invention, the clamping member 80 includes an elastic clamping part 81 and a connecting part 82 arranged along the axial direction. The connecting part 82 is connected to the grounding terminal 90. The elastic clamping part 81 has a C-shaped structure and is matched and surrounds the outer wall of the protrusion 61. A plurality of cantilever arms 83 extending toward the male end 100 are formed thereon. Each cantilever arm 83 can deform when the male end 100 is inserted to press against the inner wall of the male end body 10. An elastic part 84 protruding outward is formed in the middle of each cantilever arm 83. The protrusion 61 has a square structure, and each of its outer walls has one or more cantilever arms 83 on its periphery.
