[0022] Examples of electrical connector assemblies are Figure 1~3 Shown: including a first cable, a second cable and an electrical connector, the first cable includes a first cable core 20 and a first connection row 19 connected to the rear end of the first cable core 20, the second cable includes a second connection row 14, the first connecting row 19 and the second connecting row 14 are all copper bars, and the second connecting row 14 is a right-angled L-shaped structure. Through the screw connection holes 18 for the connection of the first connection row and the second connection row, the screw connection holes are waist-shaped holes extending in the front-rear direction. The electrical connector includes a front housing and a rear housing 13. The front housing includes a fixed housing 5 spaced from the rear housing 13 in use. The fixed housing has a first inner hole for the first cable to pass through. The housing 13 has a second inner hole for the second cable to pass through. The rear housing 13 is also a right-angled L-shaped structure. The lower end of the rear housing is provided with a connecting flange 15 for connecting with corresponding equipment. The connecting flange 15 An end face seal ring 16 and a peripheral face seal ring 17 are arranged at the place. Between the fixed housing 5 and the rear housing, there is a connection space 30 for connecting the first connection row of the first cable with the second connection row of the second cable, and the screws on the first connection row 19 and the second connection row 14 The connection hole is located in the connection space 30 . The front housing also includes a shielding sleeve 10 that guides and moves and is sleeved on the fixed housing. The shielding sleeve 10 has an escape position that allows the connection space 30 and a shielding position that blocks the connection space 30 in its moving stroke. The fixed housing 5 The rear end of the housing is provided with a fixed housing sealing ring 7, and the front end of the rear housing 13 is provided with a rear housing sealing ring 12. Through the corresponding sealing cooperation between the fixed housing sealing ring 7, the rear housing sealing ring 12 and the shielding sleeve 10, Guarantee the sealing fit relationship between the shielding sleeve 10 and the fixed housing 5 and the rear housing 13 when the shielding sleeve 10 is in the shielding position, so as to realize the sealing of the joints of the first connecting row and the second connecting row. The inner periphery of the front end of the shielding sleeve 10 is provided with a shielding sleeve inner ring platform 8, and the front and rear sides of the shielding sleeve inner ring platform 8 on the fixed housing 5 are respectively provided with a retaining spring 6 and a fixed housing outer ring platform 9. 6. The cooperation between the outer ring platform 9 of the fixed housing and the inner ring platform 8 of the shielding sleeve limits the position of the front end of the shielding sleeve when the shielding sleeve is in the blocking position; the rear end of the shielding sleeve and the front end of the rear housing are also provided with Corresponding half-connection rings 11 snap-fit into the slots 31 , and the front end of the shielding sleeve is limited when the shielding sleeve is in the shielding position through the buckle of the two plate connecting rings 11 . A stuffing ring 3 is arranged between the front end of the fixed housing 5 and the first core wire of the first cable, and the radial position of the first cable is limited and sealed by the stuffing ring 3 to ensure that the first connection row and the fixed shell The spacing between the bodies, the packing ring is fixed by the fixed nut 2 screwed on the front end of the fixed shell, the fixed nut and the front end of the fixed shell are provided with a connecting groove 4, after the radial position of the first cable is determined, after the fixed A vulcanized sleeve 1 is provided between the casing and the outer periphery of the first cable through a vulcanization process to ensure the sealing and connection strength between the first cable and the fixed casing.
[0023] The assembly process of the electrical connector assembly is as follows: the circlip is taken out from the circlip groove 21 on the fixed housing, and the circlip and the shielding sleeve are retracted together, so as to make room for the connection space such as figure 2 As shown, the first cable core wire of the first cable passes through the fixed housing, and the first cable core wire is connected with the first connecting row. The core wire is sealed, and then vulcanized to form the vulcanized sleeve; the second cable core wire is connected to the second connection row, the rear shell is sealed with the equipment, the first and second connection rows are connected with screws, and the first connection After the row and the second connecting row are connected, push the shielding sleeve backward to the shielding position. At this time, the outer ring platform of the fixed housing and the inner ring platform of the shielding sleeve stop and cooperate to restrict the shielding sleeve from continuing to move forward. In the snap ring groove on the fixed housing, the position limitation to the front end of the shielding sleeve is completed, and the two half-connecting rings are buckled on the shielding sleeve and the rear housing to complete the spacing to the rear end of the shielding sleeve.
[0024] The electrical connector does not need to use contacts to conduct current, and the current is transmitted through the cable itself, which can greatly reduce the size of the electrical connector; the first connecting row and the second connecting row are connected by screws to ensure that the first connecting row It is detachable from the second connecting row, and at the same time can ensure the tensile capacity between the first cable and the second cable; the setting of the shielding sleeve also facilitates the handling of the seal, which can be realized only by using the sealing ring. In other embodiments of the electrical connector: when the first cable and the second cable do not need to be disassembled, the first connecting row and the second connecting row can be directly welded together. Of course, at this time, the first connecting row and the second connecting row It can also be omitted, the first cable core wire of the first cable and the second cable core wire of the second cable can be directly welded together; It may not be the structure of the retaining ring, the outer ring platform of the fixed shell, and the inner ring platform of the shielding sleeve, for example, the top wire that is screwed on the shielding sleeve in the radial direction; the axial movement limit between the shielding sleeve and the rear housing is realized. The rear limit structure of the bit can also not be the structure of the card slot and the semi-connecting ring, for example, the top screw that is screwed radially on the shielding sleeve, or the sleeve connecting nut is rotated on the rear shell, and on the shielding sleeve Set the external thread that cooperates with the connecting nut; Of course, only one front and rear limit structure can be set; When the sealing ring between the rear shells can provide enough friction to limit the position of the shielding sleeve, it is enough to rely on the friction between the sealing ring and the shielding sleeve to limit the position of the shielding sleeve; the shielding sleeve and the fixed shell, the rear shell It is also possible not to seal through the sealing ring. For example, when the processing accuracy is high, the sealing can be directly achieved through the cooperation of the surface and the surface. When the electrical connector is used indoors without waterproofing, the shielding sleeve and the fixed housing , The sealing ring between the rear shells can also not be established.
