Embodiment 1

[0041] Such as Figure 1a to Figure 3b As shown, basically, the first embodiment of the electrical connector of the present invention is composed of a housing 1 , a sealing ring 2 , and a grid member 3 .

[0042] Wherein, the casing 1 is made of insulating material, such as plastic, and its upper section has a joint portion 11, and the lower part of the joint portion 11 is integrally connected with a larger skirt portion 12, and an accommodating space 121 is provided inside the skirt portion 12. , so as to accommodate and lock the sealing ring 2 and the grille 3 for the latter. The joint part 11 is used for docking with another electrical connector. Therefore, the joint part 11 axially defines more than one terminal slot 13 communicating with the accommodating space 121 for the terminals 14 to be accommodated and positioned. The wire 141 of 14 passes through the sealing ring 2 and the grid part 3 . In addition, an annular first positioning flange 15 protrudes from the top in...

Embodiment 2

[0051] Such as Figure 4 to Figure 6b As shown, the second embodiment of the electrical connector of the present invention is composed of a housing 1 , a sealing ring 2 , and a grid member 3 .

[0052] Wherein, the structures of the housing 1 and the grille 3 are the same as those of the first embodiment, and will not be repeated here.

[0053] The sealing ring 2 is different from the first embodiment in that at least one external convex rib 27 protrudes from the circumferential surface of the plug connector 21 of the sealing ring 2, such as Figure 4 As shown, it is preferable to protrude outwardly protruding ribs 27 on the peripheral surface of the plug connector 21 adjacent to the top end and the bottom end respectively. The outer side of the annular opening of the first and second circumferential positioning grooves 24, 25 radially forms a guide slope 28 inwardly, which facilitates the guiding of the positioning flanges 15, 32 into the corresponding first and second circu...

Abstract

The invention discloses an electric connector which consists of a casing body, a sealing ring and a grid element. The upper part of the casing body is provided with a joining part, the lower part is connected with a containing space of which the bottom is provided with an opening, and the inner wall of the top is convexly provided with an annular first positioning flange. The sealing ring comprises a plug element which is sleeved in the containing space, and areas among the outer walls of the top and the bottom and a through hole are respectively provided with a first annular circumferential positioning groove and a second annular circumferential positioning groove in the axial direction. The grid element is sleeved in the containing space, and the top surface of the grid element is convexly provided with a second positioning flange corresponding to the second circumferential positioning groove. When the grid element and the containing space of the casing body form locking, the plug element is pushed by the grid element, the first circumferential positioning groove and the second circumferential positioning groove are respectively spliced in the first positioning flange of the casing body and the second positioning flange of the grid element, and then the circumferential outer wall of the plug element protrudes and deforms outwards, and clings to the circumferential inner wall of the containing space.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector with a sealing function, in particular to a sealing ring for the electrical connector. Background technique [0002] According to the fact that electrical connectors are often seen in electrical products, their main purpose is to conduct power or signals. Therefore, electrical connectors have been widely used in the connection of information products and are indispensable components. [0003] In fact, the application of electrical connectors is not only limited to the aforementioned electrical products, but also widely used in the circuit system of automobiles and motorcycles as a connection of lines. Because automobiles and locomotives must run in various weather conditions, it is inevitable that foreign objects, such as liquid and dust, will enter the vehicle body. Therefore, if the electrical connector is not provided with a sealing structure, the aforementio...
