[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] like Figures 1 to 3 As shown, an embodiment of the utility model provides a connector, including a housing 1, a rubber core 2, a conductive carrier 3 and a terminal 4. The housing 1 is cylindrical, and has an installation channel 5 inside the housing 1. The installation channel 5 extends along the axial direction of the housing 1 and penetrates the housing 1.

[0030] The housing 1 has a first end and a second end opposite to each other along its axial direction. In the direction from the first end to the second end of the housing 1, the rubber core 2 and the conductive carrier 3 are sequentially installed in the installation channel 5. The rubber core 2 is sealed and connected to the first end of the housing 1, and the conductive carrier 3 is sealed and connected to the second end of the housing 1.

[0031] The rubber core 2 has a receiving cavity 6 inside, one end of the receiving cavity 6 is connected to the installation channel 5, and the other end has an opening;

[0032] The conductive carrier 3 has a conductive portion 31, and the conductive portion 31 extends into the accommodating cavity 6;

[0033] The terminal 4 is installed in the accommodating cavity 6, one end of the terminal 4 is connected to the conductive part 31, and the other end passes through the opening of the accommodating cavity 6 and extends to the outside of the housing 1. In this embodiment, the housing 1 is a straight-headed structure of a straight cylinder. Compared with the connector of the elbow, the connector of this embodiment reduces the occupied volume. At the same time, the terminal 4 is conductive, preferably a copper bar. Compared with the copper bar terminal 4 of the elbow connector, the terminal 4 of this embodiment reduces the turning structure, reduces the length of the copper bar, and then reduces the volume and production cost of the terminal 4, which is conducive to the low cost and miniaturization of the product. In addition, the conductive carrier 3 of this embodiment is a single-core cable. A single core means that there is only one conductor in an insulating layer, which mainly includes a bare copper conductor, an insulator, an aluminum foil, a braid, and a sheath from the inside to the outside. When the voltage exceeds 35kV, most of them use single-core cables. The relationship between its bare copper conductor and the metal shielding layer can be regarded as the relationship between the coil and the iron core in the primary winding of a transformer. When the single-core cable core passes current, magnetic lines of force will interlink the aluminum package or the metal shielding layer, causing an induced voltage to appear at both ends. The shield is made of soft bare or tinned copper wire braid, which has excellent anti-electromagnetic interference performance, wherein the conductive part 31 refers to the copper conductor of the cable.

[0034] In one embodiment, the terminal 4 is welded, snap-fitted or plugged into the conductive part 31. In this embodiment, the terminal 4 is ultrasonically welded to the conductive part 31, which reduces the connection structure between the terminal 4 and the conductive part 31, reduces the connection cost, and improves the stability of the terminal 4. At the same time, after the terminal 4 is welded to the conductive carrier 3, it can be inserted normally without distinguishing the forward and reverse directions of the terminal 4, which can improve the efficiency of blind operation. In other embodiments, the terminal 4 and the conductive part 31 are snap-fitted through a snap-fit ​​slot; or the terminal 4 and the conductive part 31 are fixedly connected by plugging.

[0035] In one embodiment, the terminal 4 has a first side surface and a second side surface that are opposite to each other along the thickness direction thereof, the conductive portion 31 has a third side surface and a fourth side surface that are opposite to each other along the thickness direction thereof, and the first side surface of the terminal 4 is attached to the third side surface of the conductive portion 31. In this embodiment, the first side surface of the terminal 4 and the third side surface of the conductive portion 31 are attached and welded together, so that the contact area between the terminal 4 and the conductive portion 31 can be increased, and the stability of the connection between the terminal 4 and the conductive carrier 3 can be increased, so that the signal transmission or current transmission between the terminal 4 and the conductive carrier 3 can be stably performed.

[0036] In one embodiment, the terminal 4 includes a first connecting section 41, a transition section 42 and a second connecting section 43 connected in sequence, and the first connecting section 41 is parallel to the second connecting section 43;

[0037] The second connection section 43 is connected to the conductive part 31, and the first connection section 41 extends to the outside of the housing 1. In this embodiment, a part of the first connection section 41 close to the transition section 42, the transition section 42 and the second connection section are located inside the housing 1, and a part of the first connection section 41 away from the transition section 42 is located outside the housing 1. The terminal 4 has a bent shape, so that the first connection section 41 and the second connection section 43 form a step. One side surface in the thickness direction of the conductive part 31 is welded to one side surface in the thickness direction of the second connection section 43, and at the same time, the conductive carrier 3 and the first connection section 41 can be located at the center of the housing, so that the connector of this embodiment has symmetry, which increases the aesthetics and practicality. At the same time, since the second connection section 43 is bent and misaligned relative to the first connection section 41, the end of the accommodating cavity 6 close to the conductive carrier 3 needs to accommodate the second connection section 43 and the conductive part 31, while the other end of the accommodating cavity 6 only needs to accommodate the first connection section 41. Therefore, the cross-sectional area of ​​the end of the installation cavity close to the conductive carrier 3 of this embodiment is larger than the cross-sectional area of ​​the other end.

[0038] In one embodiment, the rubber core 2 has a connecting portion 21 and a rubber core body 22 connected to each other. The rubber core body 22 is arranged in the installation channel 5. The connecting portion 21 is sleeved on the outer peripheral surface of the shell 1 and is sealed and connected to the shell 1. In this embodiment, a buckle is arranged on the outer peripheral surface of one end of the shell 1 connected to the connecting portion 21, and a slot is arranged on the connecting portion 21 corresponding to the buckle on the shell 1. The buckle can be snapped into the slot. At the same time, a sealing ring is arranged between the connecting portion 21 and the shell 1, wherein the sealing ring can be sleeved on the outer peripheral surface of the shell 1, one end of the sealing ring abuts against the contact position between the rubber core 2 and the shell 1, and the other end abuts against the step structure of the shell 1, so as to achieve the sealing between the rubber core 2 and the shell 1. In this embodiment, by arranging the connecting portion 21 on the rubber core body 22, it is also possible to prevent the rubber core 2 from being installed upside down, which has a fool-proof effect.

[0039] In one embodiment, a fastener 7 is provided at one end of the opening of the rubber core 2, and a positioning hole 44 is provided at the terminal 4 corresponding to the fastener 7, and the fastener 7 is inserted into the positioning hole 44. In this embodiment, a tubular protrusion extends from the connecting portion 21 of the rubber core 2, and a through-hole structure is provided at the protrusion corresponding to the positioning hole 44. The fastener 7 is a pin, and the copper busbar and the rubber core 2 are fixed by installing the pin in the through-hole and the positioning hole 44. In other embodiments, the fastener 7 is a bolt or other structure.

[0040] In one embodiment, the connector further includes a shielding cover 8, which is sleeved on the outer peripheral surface of the conductive carrier 3 and is located in the mounting channel 5. When in use, the current passing through the electronic device will generate a magnetic field, and by providing the shielding cover 8, the anti-interference ability of the connector of this embodiment can be improved.

[0041] In one embodiment, the connector further includes a tail cover 9, one end of which is sleeved on the outer circumference of the conductive carrier 3, and the other end is sleeved on the second end of the shell 1. In this embodiment, the conductive carrier 3 is fixed in the installation channel 5 by the tail cover 9, and the cross-sectional area of ​​the end of the tail cover 9 sleeved on the shell 1 is larger than the cross-sectional area of ​​the other end. In this embodiment, the tail cover 9 is snap-fitted or buckled with the shell 1. In other embodiments, it also includes a riveting ring 10 and a sealing ring, both of which are sleeved on the outer circumference of the conductive carrier 3, the shielding cover 8 is sleeved on the riveting ring 10, the outer end of the sealing ring abuts on the inner wall of the installation channel 5, and one end of the sealing ring abuts on the riveting ring 10, and the other end abuts on the tail cover 9.

[0042] In one embodiment, ribs are provided on the outer circumferential surface of the rubber core 2, and the ribs abut against the inner wall of the installation channel 5. In this embodiment, by providing the ribs, the rubber core 2 can be stably installed in the installation channel 5, avoiding the shaking of the rubber core 2 during use, thereby enhancing the stability of the connector of this embodiment and facilitating the subsequent maintenance of the electrical connection.

[0043] According to the connector of this embodiment, during assembly, the first step is to install the sealing ring for sealing the rubber core 2 and the housing 1 on the housing 1; the second step is to install the rubber core 2 in the direction at a position close to the first end of the housing 1 in the installation channel 5; the third step is to install the tail cover 9, the sealing ring for sealing the conductive carrier 3, the rivet ring 10 and the shielding cover 8 on the conductive carrier 3; the fourth step is to weld the terminal 4 and the conductive part 31; the fifth step is to install the welded terminal 4 and the conductive carrier 3 into the installation channel 5 of the housing 1, and position and lock the terminal 4 and the rubber core 2 by the fastener 7; the sixth step is to install the shielding cover 8, the rivet ring 10 and the sealing ring for sealing the conductive carrier 3 into the installation channel 5 of the housing 1, and buckle the tail cover 9. In this embodiment, the terminal 4 is connected to the conductive part 31, so that the terminal 4 and the conductive carrier 3 are directly in contact and electrically connected, and no intermediate connector is provided between the terminal 4 and the conductive part 31, so as to avoid the influence of the intermediate connector on the electrical connection between the terminal 4 and the conductive carrier 3, thereby increasing the stability of the electrical connection between the terminal 4 and the conductive carrier 3.
