[0045] According to the overall technical concept of the present utility model, an electrical connector is provided, comprising: a housing having a first cavity and a second cavity extending horizontally and vertically, respectively, and interpenetrating each other; a first ferrule module disposed within the first cavity, comprising a first rubber core, a first contact fixed within the first rubber core, and a first shielding member sleeved around the outside of the first rubber core; and a second ferrule module disposed within the second cavity, comprising a second rubber core, a second contact fixed within the second rubber core, and a second shielding member sleeved around the outside of the second rubber core. The first ferrule module also includes a detachable fuse fixed within the first rubber core.
[0046] like Figures 1 to 3As shown, the utility model discloses an electrical connector. The electrical connector includes a housing 10, a first ferrule module 11, and a second ferrule module 12. The housing 10 has a first cavity 110 extending in the vertical direction and a second cavity 120 extending in the horizontal direction. The first ferrule module 11 is inserted into the first cavity 110, and the second ferrule module 12 is inserted into the second cavity 120. The first ferrule module 11 includes a first rubber core 111, a first contact 113, and a first shielding member 112. The first contact 113 is arranged inside the first rubber core 111, and the first shielding member 112 is sleeved on the outside of the first rubber core 111. The second ferrule module 12 includes a second rubber core 121, a second contact 123, and a second shielding member 122. The second contact 123 is arranged inside the second rubber core 121, and the second shielding member 122 is sleeved on the outside of the second rubber core 121. The electrical connector of this embodiment has a 90° elbow shape as a whole, which reduces the space required for installation, can save about 40 to 50% of the space, and realizes a miniaturized design.
[0047] like Figures 3 to 10 As shown, the first rubber core 111 is provided with a first accommodating cavity 1111 for accommodating a first contact 113 and a third accommodating cavity 1112 for accommodating a fuse 114. The first contact 113 is a male terminal. After being installed into the first rubber core 111 from the bottom, the male terminal is secured by a locking member 115 provided on the side wall 1227 of the first rubber core 111 to prevent the male terminal from falling out. Specifically, the male terminal includes a plug-in end 1131 and a connection end 1132. A boss is provided on the side of the male terminal facing the connection end 1132. The locking member 115 is inserted along the radial direction of the first rubber core 111 and abuts against the boss to achieve positioning and fixing of the male terminal. The fuse 114 can be set as a fuse. The direction in which the fuse 114 is inserted into the first rubber core 111 is opposite to the direction in which the male terminal is inserted into the first rubber core 111, that is, the fuse 114 is installed from the top of the first rubber core 111, which facilitates the disassembly and maintenance of the fuse 114.
[0048] like Figures 3 to 10 As shown, the second rubber core 121 is provided with a second accommodating cavity 1211, within which is located a mounting seat 1212 for a second contact 123. Second contact 123 is a terminal with a 90-degree insertion angle. Second contact 123 is stamped from metal. One end of the second contact 123 is a crown spring-like structure for connecting to fuse 114. This provides multiple contact points, excellent seismic resistance, and facilitates maintenance and replacement of fuse 114. The other end, with a crown spring side coil, connects to a cable, eliminating the need for 90-degree wiring for fuse 114.
[0049] like Figures 3 to 10As shown, the first shielding member 112 is stamped from metal into a hollow cylindrical shape. A first snap-on spring tab 1121 for snapping onto the housing 10 is provided on the sidewall 1227 of the first shielding member 112 near the second shielding member 122. A second snap-on spring tab 1122 for snapping onto the first rubber core 111 is provided on the sidewall 1227 of the first shielding member 112 near the opening of the first cavity 110. In the illustrated embodiment, a curled edge 1123 is further formed at the front end of the first shielding member 112, which engages with the front edge of the first rubber core 111.
[0050] like Figures 3 to 10 As shown, the second shielding member 122 is also stamped from metal and has a top wall 1225, a bottom wall 1226, a pair of side walls 1227, and a front wall 1228. The front wall 1228 is connected to the top wall 1225, the bottom wall 1226, and the pair of side walls 1227 to form a cylindrical insertion opening 1229. The insertion opening 1229 is provided with a plurality of bent portions 1221 that are rolled inward toward one end of the first shielding member 112. The inwardly curled design of the bent portions 1221 allows for a smaller installation gap between the second shielding member 122 and the first shielding member 112 when they are installed perpendicularly. This makes it easier and simpler for the entire electrical connector to achieve 360° shielding. The simple structure and reduced number of parts significantly reduce the process difficulty and production cost. The side wall 1227 is provided with a third snap-on spring 1222 that snaps into the housing 10 and a fourth snap-on spring 1223 that snaps into the second rubber core 121. Correspondingly, the side wall 1227 of the second rubber core 121 is provided with a fifth engaging spring 1214 that cooperates with the fourth engaging spring 1223. An end of the second shielding member 122 away from the front end wall 1228 is formed with an installation opening, and a shielding claw 1224 is provided in the installation opening.
[0051] like Figure 4 and Figure 5 As shown, the second rubber core 121 is assembled into the interior of the second shielding member 122. A snap-fit groove 1213 is provided on the free end of the second accommodating cavity 1211 near the bend 1221. The inner diameter of the snap-fit groove 1213 is slightly smaller than that of the second shielding member 122. This facilitates contact between the first shielding member 112 and the second shielding member 122 via the multiple bends 1221 when the first ferrule module 11 is plugged into the second ferrule module 12, and the first ferrule module 11 is secured in the snap-fit groove 1213.
[0052] like Figures 3 to 8 As shown, a high voltage interlocking member 116 is further provided inside the first rubber core 111 . The high voltage interlocking member 116 is plugged into the first rubber core 111 to transmit signals when connected to a mating connector.
[0053] like Figures 3 to 8As shown, the electrical connector of this embodiment further includes a flange 13, which is inserted through a mounting hole via fasteners 15 for secure installation on a mounting panel of an electrical device. The flange 13 integrally extends outward from the outer wall 1227 of the housing 10, forming a flat plate or other suitable shape for mounting. A seal 16 is also provided on the side of the flange 13 facing the panel, which is used to establish a waterproof seal between the electrical connector and the mounting panel of the electrical device.
[0054] like Figures 1 to 3 As shown, the electrical connector of this embodiment further includes a first cover 117 and a second cover 124, both of which are injection-molded components. The first cover 117 snaps onto the top of the fuse 114 and is removable for easy maintenance and replacement of the fuse 114. The second cover 124 snaps onto the side of the second rubber core 121 facing the mounting opening and is used to secure the second contact 123.
[0055] During installation of the electrical connector of this embodiment, the second rubber core 121 is first inserted through the mounting opening into the second shielding member 122, then into the second cavity 120. The second contact 123 and the second cover 124 are then installed. The first rubber core 111, which integrates the first contact 113 and the high-voltage interlocking member 116, is then installed into the first shielding member 112. After being installed into the first cavity 110, the fuse 114 and the first cover 117 are then installed from the top of the first cavity 110. It will be understood that the connection terminal 1132 of the first contact 113 is used to connect to a cable and exit through the second cavity 120, while the male terminal's plug-in end is designed to mate with the female terminal. One end of the high-voltage interlocking member 116 is used to transmit signals when connected to a mating connector, while the other end is used to connect to a cable and exit through the second cavity 120. The end of the second contact 123 not in contact with the fuse 114 is used to connect to a cable and exit through the second cavity 120. The second cover 124 is provided with corresponding outlet holes for these cables.
[0056] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description.
