[0021] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0022] Please refer to Figures 1 to 3 As shown, the present invention provides a well-sealed automotive connector assembly, comprising a male connector 1 with a seal A3 mounted on one end. One end of the seal A3 is secured to a wiring harness A5 connected to the male connector 1 via a fixed snap ring 10. Specifically, the wiring harness A5 passes through one end of the seal A3, is encircled by a fixed snap ring 10, and then secured by a setscrew (not shown). A movable snap ring 7 is mounted on the other end of the seal A3, which is movably mounted to the female connector 2.
[0023] Furthermore, the connector 1 internally includes at least a plurality of male terminals (unnumbered). These terminals are secured within a male insulating body (unnumbered) made of insulating material and assembled within the connector 1. One end of each of these terminals is electrically connected to the wiring harness A5. Specifically, the connector 1 includes a cylindrical male housing (unnumbered), within which the male insulating body, which holds the plurality of male terminals, is assembled and secured. The plurality of male terminals protrude forward from the male insulating body to form a cantilevered structure.
[0024] Please refer to Figure 1 and Figure 2As shown, a seal B4 is mounted on one end of the female connector 2. One end of the seal B4 is secured to the wiring harness B6 behind the female connector 2 via a retaining ring 10. Specifically, the wiring harness B6 passes through one end of the seal B4 and is secured by a retaining ring 10 that surrounds the seal B4 at one end and is then tightened with a setscrew (not shown). The other end of the seal B4 is secured to the female connector 2 via a retaining ring 10. Specifically, the retaining ring 10 is secured by a setscrew (not shown) that surrounds the junction between the other end of the seal B4 and the female connector 2. The other end of the seal B4 and the connecting female head 2 can be combined in a partially nested manner at the combining position; or they can be combined by direct end face contact. When the other end of the seal B4 and the corresponding end of the connecting female head 2 are combined by direct end face contact, the other end of the seal B4 and the corresponding end of the connecting female head 2 form a concave ring on their respective outer peripheral surfaces (or can also be designed to protrude from their respective outer peripheral surfaces to form a convex ring). The fixing clamp 10 can be designed to have a cross-sectional [shaped structure, for example, and can be correspondingly clamped on the concave ring / convex ring to achieve axial fixation of the seal B4 and the connecting female head 2 by the fixing clamp 10.
[0025] Furthermore, the female connector 2 includes a female insulating body (unnumbered), multiple female terminals (unnumbered) fixed within the insulating base, and a cylindrical female housing (unnumbered) surrounding the female insulating body. An annular mating cavity (unnumbered) is formed between the female insulating body and the cylindrical female housing. When the female connector 2 is mated with the male connector 1, the cylindrical male housing is inserted into the annular mating cavity, the female insulating body is inserted into the cylindrical male housing, and the male terminals are inserted into the female insulating body and electrically contact the female terminals.
[0026] Please refer to Figures 1 to 3As shown, the movable snap ring 7 comprises two movable snap ring arms 11 of identical structure. Each movable snap ring arm 11 has a semicircular structure. The movable snap ring arms 11 are made of metal, preferably stainless steel. Each movable snap ring arm 11 has a certain degree of elasticity and strength to accommodate minor deformation during the connection process and maintain the stability of the connection. A connecting rod 13 is located at one end of the two movable snap ring arms 11. Rotating the two movable snap ring arms 11 together, the two movable snap ring arms 11 can rotate about the axis of the connecting rod 13, thereby allowing the movable snap ring 7 to make necessary adjustments during the connection process. Specifically, one end of each movable snap ring arm 11 is inserted through the connecting rod 13. In a preferred embodiment, one end of one movable snap ring arm 11 forms two rotating ears (not shown) spaced apart along the axial direction of the connecting female connector 2 (i.e., the direction of insertion and removal between the connecting male connector 1 and the connecting female connector 2). The corresponding end of the other movable snap ring arm 11 forms a mating ear (not shown). The mating ear is inserted between the two rotating ears and is fixed through the connecting rod 13. The connecting rod 13 enables the two movable snap ring arms 11 to work as a whole. The female connector 2 also includes a locking mechanism 12, which is installed at the other end of the two movable snap ring arms 11. The main function of the locking mechanism 12 is to lock the two movable snap ring arms 11 together when the male connector 1 and the female connector 2 are connected to ensure the security of the connection.
[0027] It is worth noting that the locking mechanism 12 can secure one end of the two movable snap ring arms 11 via a bolted connection. Specifically, the other end of one movable snap ring arm 11 extends outwardly in the radial direction of the connecting female connector 2 to form a first locking tab (unnumbered), while the other end of the other movable snap ring arm 11 extends outwardly in the radial direction of the connecting female connector 2 to form a second locking tab (unnumbered). The bolts respectively pass through the first and second locking tabs along the circumferential direction of the connecting female connector 2 to achieve locking. The bolted connection is relatively simple and easy to install and remove, which makes disassembly of the locking mechanism 12 more convenient.
[0028] More notably, a sealing ring 14 is installed between the inner surface of the two movable snap ring arms 11 and the outer surface of the joint between the female connector 2 and the male connector 1. The sealing ring 14 has good elasticity and sealing performance, and can fit tightly to the contact surface when under pressure to form an effective sealing barrier. The shape and size of the sealing ring 14 are usually customized according to the shape and size of the contact surface of the female connector 2, the male connector 1 and the movable snap ring arms 11 to ensure the best sealing effect.
[0029] In a preferred embodiment, a groove A8 and a groove B9 are formed on the female connector 2. The shape and size of the groove A8 generally match those of the movable snap ring 7 to ensure that the movable snap ring 7 can be held in the correct position therein. The shape and size of the groove B9 match those of the fixed snap ring 10 to ensure that the fixed snap ring 10 can be securely installed in the groove B9 and is not easily loosened or fallen off.
[0030] Preferably, the sealing material used for the sealing member A3 and the sealing member B4 is a high-elasticity rubber material.
[0031] The specific docking assembly method is as follows:
[0032] First, connect the male connector 1 and the female connector 2 so that the male connector 1 and the female connector 2 are connected in place. Next, align the movable snap ring 7 with the position of the groove A8, and then adjust the locking mechanism 12. Driven by the locking mechanism 12, the movable snap ring 7 is gradually tightened in the groove A8. At this time, one end of the seal A3 has been sealed and installed with the wiring harness A5 through the fixed snap ring 10, and the other end is sealed and installed with the female connector 2. One end of the seal B4 has been sealed and connected with the wiring harness B6 through the fixed snap ring 10, and the other end is sealed and connected with the female connector 2 through the fixed snap ring 10.
[0033] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
