[0021] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0022] like Figures 1 to 5 As shown, the utility model provides a connector for electrically connecting a wire end and a board end, which includes a board end connection shell 1, a wire end connection shell 2 that can be inserted into the board end connection shell 1, a snap-fit ​​assembly 3, a wire end rubber core 4 installed in the wire end connection shell 2, a wire end terminal 5 inserted in the wire end rubber core 4, a sealing ring 6 sleeved on the outside of the wire end connection shell 2, a board end terminal 7 inserted in the board end connection shell 1 and a sealed space 8 arranged in the wire end connection shell 2; one end of the wire end terminal 5 protrudes into the sealed space 8; when the wire end connection shell 2 is inserted into the board end connection shell 1, the wire end terminal 5 is electrically connected to the board end terminal 7 and the sealing ring 6 abuts against the inner wall of the board end connection shell 1, and the snap-fit ​​assembly 3 can lock or unlock the wire end connection shell 2 and the board end connection shell 1.

[0023] Specifically, the sealing filler can be poured into the sealed space 8, and the sealing filler can be made of existing resin materials. In the actual installation process, the wire end rubber core 4 is installed in the wire end connection housing 2, and then the wire end terminal 5 is pressed into the wire end rubber core 4, and the wire is welded to one end of the wire end terminal 5 protruding into the sealed space 8, and then the resin is poured into the sealed space 8 to seal the connection between the wire and the wire end terminal 5, and finally the wire end connection housing 2 is inserted into the board end connection housing 1, and the sealing ring 6 seals the gap between the inner wall of the board end connection housing 1 and the outer wall of the wire end connection housing 2, and the board end connection housing 1 and the wire end connection housing 2 are locked by the snap-fit ​​assembly 3, so as to achieve a stable connection. The wire end connection housing 2 of the utility model is inserted into the board end connection housing 1, and the gap at the connection is sealed by the sealing ring 6, and the connection between the wire and the wire end terminal 5 is sealed by the sealing filler, which improves the air tightness and service life of the utility model. The wire end rubber core 4 of different specifications or models can be selected to be installed in the wire end connection housing 2 to adapt to the continuous wire end terminal 5, further improving the practicality and utilization rate of the utility model. The wire end connection housing 2 and the board end connection housing 1 are conveniently locked and unlocked by the buckle assembly 3.

[0024] Furthermore, the connector further comprises a limiting boss 9 formed by protruding outward from the inner wall of the wire end connection housing 2 , and one end of the wire end rubber core 4 abuts against the limiting boss 9 .

[0025] Specifically, the sealing space 8 is on one side of the limiting boss 9, and the wire end rubber core 4 is on the other side of the limiting boss 9. In actual use, when the wire end rubber core 4 is inserted into the wire end connection housing 2, until the limiting boss 9 contacts the wire end rubber core 4, the wire end rubber core 4 is installed in place. The limiting boss 9 is added to facilitate the accurate and rapid installation of the wire end rubber core 4.

[0026] Furthermore, the connector further comprises a mounting groove 12 which is formed by a recessed outer wall of the wire end connection housing 2 , and the sealing ring 6 is mounted in the mounting groove 12 .

[0027] The installation groove 12 is added to prevent the sealing ring 6 from moving or deviating when the wire end connection housing 2 is inserted into the board end connection housing 1, thereby improving the stability of the utility model during use.

[0028] Furthermore, the connector also includes a plurality of grooves 13 formed by the outer side wall of the sealing ring 6 being recessed inwardly.

[0029] During actual use, multiple grooves 13 are added. When the wire end connection shell 2 is inserted into the board end connection shell 1, the inner wall of the board end connection shell 1 will squeeze the sealing ring 6, causing the sealing ring 6 to deform and stretch into the groove 13, so that the sealing ring 6 is in full contact with the board end connection shell 1, thereby improving the sealing performance.

[0030] Furthermore, the connector further comprises a positioning protrusion 10 arranged on the inner wall of the wire end connection housing 2 and a positioning groove 11 arranged on the wire end rubber core 4, and the positioning protrusion 10 and the positioning groove 11 are matched with each other.

[0031] In actual use, the positioning protrusion 10 and the positioning groove 11 are additionally provided to facilitate the rapid alignment and installation of the rubber core positioning protrusion 10 and the wire end connection housing 2 .

[0032] Furthermore, the snap-fitting assembly 3 includes an elastic pressing portion 15 arranged on the wire end connection shell 2, a male buckle 16 arranged on one end of the elastic pressing portion 15, and a female buckle 17 arranged on the board end connection shell 1, the female buckle 17 can be snapped with the male buckle 16, the female buckle 17 is provided with a first inclined surface 18, and the male buckle 16 is provided with a second inclined surface 19, and the first inclined surface 18 and the second inclined surface 19 can interfere with each other.

[0033] In actual use, when the wire end connection housing 2 is inserted into the board end connection housing 1, the first inclined surface 18 and the second inclined surface 19 collide with each other, and the female buckle 17 contacts the male buckle 16, so that the male buckle 16 drives the elastic pressing part 15 to move upward until the male buckle 16 and the female buckle 17 are aligned and buckled. When it is necessary to unlock the wire end connection housing 2 and the board end connection housing 1, by pressing down on one end of the elastic pressing part 15, the elastic pressing part 15 is elastically deformed, and the male buckle 16 at the other end of the elastic pressing part 15 is driven to move upward, so as to unlock the wire end connection housing 2 and the board end connection housing 1. The structure of the buckling assembly 3 is simple and compact, and the elastic pressing part 15, the male buckle 16 and the wire end connection housing 2 can be of an integrated structure, which is easy to produce and low in cost.

[0034] Furthermore, a slot 14 is provided on the board end connection housing 1, and the line end connection housing 2 can be inserted into the slot 14; the slot 14 is asymmetrically arranged.

[0035] In the actual plug-in process, the slot 14 is asymmetrically arranged, and when the terminal connection housing 2 is inserted into the slot 14, there is a strong visual anti-fool effect, automatic anti-fool, and convenient plug-in.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
