[0003] As the safety performance of connectors improves, the existing two-core metal shielded high-voltage connectors have become increasingly complex in design, and their size has gradually increased, installation has become complex, and costs have increased. It is necessary to develop a two-core metal shielded high-voltage connector that is both safe and has a small number of parts and is easier to install. Utility Model Content

[0004] The utility model overcomes the shortcomings of the prior art and provides a two-core metal shielded high-voltage connector which is easy to install, so as to solve the problems of the existing connector having a complex structure and being difficult to install.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A two-core metal shielded high-voltage connector that is easy to install, comprising an upper cover assembly, a shell assembly, a front-hole insulator assembly, a copper busbar, and a cable assembly;

[0007] The upper cover assembly comprises an upper cover and an upper sealing ring, wherein the upper sealing ring is installed below the upper cover, and the upper cover is installed above the shell assembly;

[0008] The housing assembly comprises a housing, the housing is provided with a cavity extending vertically therethrough, and one side is provided with two mounting tubes;

The rear hole insulator, the connecting terminal, the shielding sleeve, the shielding ring, the sealing body, and the tail cover are installed in sequence. The cable is installed in the cable assembly, and the cable assembly is installed in the installation tube of the housing.

[0012] The connecting terminal is fixedly connected to the copper busbar inside the housing.

[0013] Compared with general metal shielded high-voltage connectors, the present application simplifies the structure of the upper cover and uses the front-hole insulator assembly as the lower sealing assembly of the shell, reducing the parts of the connector. At the same time, since the shell cavity is through-through from top to bottom, it is easy to operate and can easily realize the fixed connection between the connecting terminal and the copper busbar inside the shell, greatly simplifying the assembly of the connector.

[0014] A further technical solution is that a fixing hole is provided at the tail of the connecting terminal;

[0015] The copper busbar is L-shaped, wherein the longer side passes through the copper busbar via hole, and the shorter side is provided with a fixing hole;

[0016] The housing assembly comprises a fixing piece, which passes through a fixing hole at a tail of the connecting terminal and a fixing hole of the copper busbar and is fixed in the housing.

[0017] A further technical solution is that the fixing piece is a bolt, and a nut matching the bolt is riveted onto the upper portion of the front-hole insulator.

[0018] The connection terminal and the copper busbar can be stably connected by passing the bolts through the fixing holes at the rear of the connection terminal and the fixing holes of the copper busbar, and the use of bolts and nuts to connect is also convenient for later disassembly and maintenance.

[0019] A further technical solution is that a matching buckle is provided between the tail cover and the housing mounting tube.

[0020] A further technical solution is that a matching buckle is provided between the rear hole insulator and the shell.

[0021] Using a clip can further facilitate the installation between the cable assembly and the housing.

[0022] A further technical solution is that an undercut limiter is provided in the copper busbar via hole;

[0023] The copper busbar is provided with a groove which cooperates with the undercut limiter.

[0024] A further technical solution is that the upper cover and the shell are fixedly connected by bolts.

[0025] A further technical solution is that the front-hole insulator assembly and the shell are fixedly connected by bolts.

[0026] Since sealing rings are arranged between the upper cover and the shell, and between the front-hole insulator assembly and the shell, the sealing rings can play a better role by fixing with bolts.

[0027] Compared with the prior art, the utility model has at least the following beneficial effects: the utility model simplifies the structure of the upper cover and uses the front-hole insulator assembly as the lower sealing assembly of the shell, thereby reducing the parts of the connector, and because the shell cavity is through-through from top to bottom, it is convenient to operate, and by using fixings to fix the connecting cable assembly and the copper busbar, the connecting terminal and the copper busbar can be easily fixedly connected inside the shell, which greatly simplifies the assembly of the connector.
