Description

Technical Field

[0001] The invention relates to the field of charging pile equipment, and in particular to a convenient installation structure for concealed electric wires of a charging pile. Background Art

[0002] With the popularization and promotion of new energy vehicles, a variety of charging pile products have also flooded into the market. When the charging pile products are sent to customers, it is necessary to connect the incoming wire harness from the power grid to the charging pile products to complete the installation. There are two main types of existing charging pile incoming wire installation structures: the first solution is to use a sealed waterproof connector structure alone. During installation, unscrew the tail cover of the waterproof connector, insert the incoming wire harness into the connector and extend it into the charging pile body. At the same time, you need to use a screwdriver or other tools to open the cover or panel of the charging pile box, lock the incoming wire and the terminal seat reserved for the internal circuit board with screws, then cover the cover or panel, re-lock it with tools, and finally tighten the tail cover of the waterproof connector to complete the installation of the incoming wire; the second The first solution is to use a sealed cabin plus a sealed waterproof joint structure. The sealed cabin is a sealed box body with an opening at one end, which is installed on the surface of the charging pile body (usually the bottom surface of the pile body) with screws. The open end is fitted and sealed with the pile body to form a sealed cavity. A waterproof flange sealing joint is installed at the rear end of the cabin body. Inside the sealed cabin, a through-wall terminal is installed on the charging pile body. The interface of the through-wall terminal on the side inside the charging pile is connected to the incoming line terminal seat of the charging pile circuit board with a wiring harness. During installation, unscrew the tail cover of the waterproof joint, insert the incoming wire harness into the joint and extend it into the sealed cabin, remove the sealed cabin body, connect the incoming wire harness to the reserved through-wall terminal interface, tighten the wire harness, install it back into the sealed cabin, and finally tighten the tail cover of the waterproof joint to complete the installation of the incoming line.

[0003] When a sealed waterproof connector structure is used alone, it is necessary to open the outer shell of the charging pile body when installing the incoming wires, and then insert the incoming wire harness into the charging pile body through the sealed waterproof connector to complete the connection of the wire harness. The operation is complicated and cumbersome. Opening the charging pile body also poses a risk of damaging the internal wire harness or parts of the charging pile body. The use of a sealed cabin plus a sealed waterproof connector structure is relatively optimized. Only the sealed cabin needs to be opened to complete the connection of the incoming wire harness through the through-wall terminal. However, the sealed cabin is often large in size and protrudes from the outside of the charging pile body, affecting the overall coordination and aesthetics of the product. At the same time, the protruding structure also increases the installation space required for the product, reduces applicability, and has additional risks of bumps and collisions. Therefore, a hidden and convenient installation structure for the incoming wires of the charging pile is urgently needed. Summary of the invention

[0004] The purpose of the present invention is to solve the problems of cumbersome installation of the incoming wires of existing charging pile products or unsightly structures and easy bumping, and to provide a hidden and convenient installation structure for the incoming wires of the charging pile.

[0011] Preferably, a through hole matching the sealing waterproof joint is provided on the bottom plate, and the terminal mounting bracket is a U-shaped structure.

[0012] Preferably, the sealing pad is made of rubber or foam, and the bottom plate and the charging pile body form a sealing structure through the sealing pad. The through-wall terminal consists of two parts, an upper part and a lower part.

[0013] Preferably, the internal wiring harness is connected to the output pin of the internal circuit board of the charging pile, and the through-wall terminal is fixedly connected to the internal wiring harness and the incoming wiring harness by fastening bolts. Compared with the prior art, the present invention has the following beneficial effects: First, the present invention provides an inlet opening and a matching pull-out inlet mounting bracket to hide the through-wall terminal together with part of the bracket into the interior of the charging pile body, which greatly optimizes the appearance of the charging pile product, retains the overall coordination of the product, and improves the aesthetics.

[0014] Second, the present invention provides a retractable incoming line installation bracket and a through-wall terminal, so that the incoming line harness can be installed without opening the outer shell of the charging pile body, which is convenient and efficient, and there is no risk of damaging the inside of the charging pile.

[0015] Third, the present invention sets a positioning card plate to limit the possible misalignment when the incoming line installation bracket is pulled out, so that the entire pulling process is smooth and accurate. At the same time, the positioning card plate strengthens the structural strength of the incoming line installation bracket, and the entire bracket is firm and reliable.

[0016] Fourth, the present invention provides a protruding structure on the plane of the terminal mounting bracket, which cooperates with the limit plate to achieve the function of the incoming line mounting bracket being locked when it is pulled out to the extreme position, thereby avoiding the risk of the bracket being pulled out of the charging pile body as a whole and damaging the internal wiring harness.

[0017] Fifth, the present invention has a simple and reliable structure and low production cost. BRIEF DESCRIPTION OF THE DRAWINGS
