DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1, as Figure 1 and Figure 2 As shown, a through-cylinder connector includes a terminal body 1 and an insulating shell 9 wrapped around the terminal body 1, and a protective cap 2 for protecting the terminal body 1 is detachably connected to the insulating shell 9. The protective cap 2 is detachably connected to the insulating shell 9, that is, the protective cap 2 and the insulating shell 9 are separately molded and manufactured, which simplifies the manufacturing process, reduces the manufacturing difficulty, and relatively reduces the production cost, and solves the technical problems in the prior art that the molding process of the protective cap integrally molded with the insulating layer is relatively complicated, it is not easy to manufacture, and the cost of connecting with the outer shell is high.

[0028] It should be noted that the through-cylinder connector of the present application is mainly used in automotive PDU, integrated box and other components. It is set to penetrate the cylinder body, realize the through-cylinder connector and the metal contact part in the cylinder body, and play the role of transmitting current and signals.

[0029] Embodiment 2, on the basis of embodiment 1, as Figure 1 and Figure 2As shown, a through-cylinder connector is provided with a connection structure between the insulating shell 9 and the protective cap 2, and the protective cap 2 is hooked and matched with the insulating shell 9 through the connection structure. It should be noted that the through-cylinder connector currently used generally includes contacts, shell components, protective caps, sealing rings, pull ropes and other components. The through-cylinder connector has many components. Once the protective cap on the through-cylinder connector is directional connected to the shell component, on the one hand, the wire outlet method is single, which is not conducive to realizing multi-directional outlet. On the other hand, during assembly, attention should be paid to the installation direction, resulting in low assembly efficiency and high overall production cost. The connection structure of the present application is set to reflect the detachability between the insulating shell 9 and the protective cap 2. At the same time, the protective cap 2 is hung and matched with the insulating shell 9 through the connection structure, including the forward hanging and matching of the protective cap 2 with the insulating shell 9 through the connection structure and the reverse hanging and matching of the protective cap 2 with the insulating shell 9 through the connection structure, that is, the protective cap 2 can be hung with the insulating shell 9 regardless of whether it is in the forward or reverse direction, avoiding the directional connection between the protective cap and the outer shell component on the through-cylinder connector, resulting in a single wire outlet method, which is not conducive to achieving multi-directional wire outlet. At the same time, during assembly, the protective cap 2 can be hung with the insulating shell 9 regardless of whether it is in the forward or reverse direction, and there is no need to pay attention to the installation direction. The assembly efficiency is improved and the overall production cost is reduced.
