[0035] Compared with the existing connector, a sealant 61 is provided on the fixing plate 6. The sealant 61 is glued and fixed to the fixing plate 6 during production. In this way, each time the sealant 61 is reinstalled, there is no need to handle or adjust the sealant 61. It can be fixed directly with screws, which is convenient and quick.
[0036] At the same time, the provision of the elastic sealant 61 can reduce the assembly process and the production process of parts while ensuring the sealing of the fixing plate 6, thereby effectively reducing the production cost.
[0037] Specifically, the sealant 61 is formed by coating with a rubber ring or integrally injection-molded;
[0038] The preferred method is coating and molding, which is simple to process; of course, it can also be fixed by gluing;
[0039] At least two sides of the fixing plate 6 are provided with column holes 62 , and the column holes 62 are provided with metal bushings 63 , wherein the combination between the column holes and the metal bushings facilitates the connection between the screws and the fixing plate 6 and improves the service life.
[0040] The male rubber shell 20 and the female rubber shell 10 are defined as the front end and the position away from the plug-in end is the back end. The length of the male rubber shell 20 is about half the length of the female rubber shell 10 (usually less than half), so the length is limited.
[0041] in Figure 1 There are two rows of terminals. Figure 2 There is a row of terminals.
[0042] Specifically, a positioning cavity 31 is provided between the front end of the partition 13 and the front end of the female rubber shell 10, and a recessed slot is provided at the rear end of the isolation channel 23 of the male rubber shell 20, and a sealing ring 32 is provided in the recessed slot.
[0043] When the male rubber shell 20 and the female rubber shell 10 are plugged into each other, the outer peripheral wall of the sealing ring 32 abuts against the inner peripheral wall of the positioning cavity 31, thereby achieving sealing of the plug-in end.
[0044] Specifically, when the rear end of the male terminal 11 is a wire end terminal, the rear end of the female plastic shell 10 is provided with a female end accommodating cavity 4, and the female end accommodating cavity 4 is installed with a female end sealing plug 41. The female end sealing plug 41 is provided with a female end through-hole 42 for the cable to pass through, and the rear wall of the female end sealing plug 41 is provided with a female end back cover 43 that is clamped in the female end accommodating cavity 4. The arrangement of the female end sealing plug 41 and the female end back cover 43 ensures the sealing of the wire end, thereby ensuring the waterproofness of the cable.
[0045] Specifically, when the rear end of the female terminal is a wire end terminal, the rear end of the male plastic housing 20 is provided with a male end accommodating cavity 5, and the male end accommodating cavity 5 is installed with a male end sealing plug 51. The male end sealing plug 51 has a male end through-hole 52 for the cable to pass through, and the rear wall of the male end sealing plug 51 is provided with a male end rear cover 53 that is clamped in the male end accommodating cavity 5. The arrangement of the male end sealing plug 51 and the male end rear cover 53 ensures the sealing of the wire end and the waterproofness of the cable.
[0046] Specifically, the upper wall of the female rubber shell 10 is provided with a rib 71, and the female end rear cover 43 is provided with a guide groove 72 that matches the rib 71.
[0047] Buckle grooves 74 are provided on both sides of the female end rear cover 43, and buckle portions 73 that match the buckle grooves are provided on both sides of the plastic shell. The detachable structure between the female end rear cover 43 and the female plastic shell 10 is the same or similar to the structure of the same male plastic shell 20 and the male end rear cover 53.
[0048] Specifically, the partition 13 is a stepped portion 8 that is wide at the top and narrow at the bottom, and the plug-in portion 22 is narrow at the top and wide at the bottom. Adjacent plug-in portions 22 form an isolation channel 23 that is wide at the top and narrow at the bottom, thereby achieving fool-proofing during insertion and avoiding the problem of reverse insertion.
[0049] Specifically, the inner wall of the female terminal located in the slot 12 is provided with a first swing arm 91, and the first swing arm 91 is hooked with the middle part of the male terminal 11;
[0050] The male terminal 11 is provided with a second swing arm 92 on the inner wall of the positioning groove. The second swing arm is hooked with the middle part of the female terminal. The first swing arm prevents the male terminal 11 from moving backward, and the second swing arm prevents the female terminal from moving backward.
[0051] Specifically, the locking device includes a snap-fit groove 100 provided on the upper wall of the female rubber shell 10 and a support arm 101 extending forward from the male rubber shell 20. The front end of the support arm is provided with a snap-fit portion 102 that hooks into the snap-fit groove 100, and the middle portion of the support arm is provided with a pressing portion 103.
