Description
Technical Field
[0001] This utility model relates to the field of charging docks, and more particularly to a mounting structure for the signal terminals of a megawatt charging dock. Background Technology
[0002] With the rapid development of the electric vehicle industry, users' demands for charging speed are constantly increasing, and megawatt-level charging technology has gradually entered the stage of comprehensive promotion and widespread application. Because megawatt charging sockets need to withstand higher voltages and larger currents, their overall structure has become correspondingly larger and more complex. However, the control leads, which are the core of system communication and control, cannot be reduced, and may even need to be increased to ensure the reliability of the entire control process.
[0003] In existing technologies, signal modules must be rationally arranged within a limited space. However, the internal space of megawatt charging bases is often small and has height differences, which greatly increases the difficulty of installing and positioning signal terminals and PE terminals. As a result, signal modules are often fixed at multiple points using screws, pressure plates, etc. This not only makes the installation process cumbersome and inefficient, but also easily leads to inaccurate positioning or insecure installation, making it difficult to meet the needs of rapid assembly of megawatt charging bases and affecting the overall installation efficiency. Utility Model Content
[0004] The purpose of this invention is to provide an installation structure for the signal terminal of a megawatt charging socket, which solves the problems of difficult installation and assembly and reduced installation efficiency.
[0005] To achieve this objective, the present invention adopts the following technical solution: A mounting structure for a megawatt charging socket signal terminal includes: a signal component and a mounting base; The signal assembly includes: a signal bracket, a PE terminal, a signal terminal, a first circular ring, a second circular ring, and screws. The signal bracket is fixedly connected to the mounting base by screws. The PE terminal and the signal terminal are respectively disposed at both ends of the signal bracket. The outer surface of the PE terminal is sleeved with the first circular ring, and the outer surface of the signal terminal is sleeved with the second circular ring. The mounting base has a signal hole and a PE hole inside. The signal hole is fixedly connected to a signal terminal. The PE hole is located below the signal hole and is fixedly connected to a PE terminal. A screw hole is provided between the signal hole and the PE hole, and the screw is threaded into the screw hole.
[0006] Preferably, the signal bracket has a screw through hole, which is internally connected to a screw thread. The end of the signal bracket away from the screw through hole has a PE locking groove, and the outer surface of the PE terminal has a PE locking position. The PE terminal is locked into the PE locking groove through the PE locking position.
[0007] Preferably, the signal bracket has a signal locking groove at one end near the screw through hole, and the signal terminal has a signal locking position on its outer surface. The signal terminal is locked into the signal locking groove through the signal locking position. The mounting base has a mounting groove inside, and the signal component is disposed inside the mounting groove.
[0008] Preferably, the mounting base has a mounting slot inside, and the signal component is disposed inside the mounting slot.
[0009] Preferably, the signal clip and PE clip are horizontally connected.
[0010] Preferably, the signal hole and the PE hole are connected to the signal slot and the PE slot, respectively.
[0011] Preferably, the screw through hole and the screw hole are on the same straight line.
[0012] Compared with the prior art, the present invention has the following beneficial effects: By setting PE terminals and signal terminals at both ends of the signal bracket, and fitting a first and second circular ring onto its outer surface, and then fixing the entire signal bracket to the mounting base with screws, the PE terminals and signal terminals can be inserted into the PE holes and signal holes on the mounting base respectively for positioning and installation. This avoids the cumbersome process of tightening multiple pressure plates and screws one by one in traditional structures, thus greatly simplifying the installation steps and improving assembly efficiency. At the same time, the circular rings between the terminals and the holes can form a radial seal during insertion, ensuring smooth insertion during installation and providing reliable waterproof and dustproof protection after installation, preventing terminal corrosion and signal attenuation caused by moisture and impurities. In addition, screw holes are pre-set between the signal holes and PE holes and connected to the screw threads, allowing the screws to be directly tightened after assembly, achieving stable overall installation of the signal component and the mounting base, and solving the problem of difficult installation and assembly.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] refer to Figure 1 - Figure 9 As shown, this utility model embodiment provides an installation structure for a megawatt charging socket signal terminal, including: a signal component 1 and a mounting base 2; The signal assembly 1 includes: a signal bracket 101, a PE terminal 102, a signal terminal 103, a first circular ring 104, a second circular ring 105, and screws 106. The signal bracket 101 is fixedly connected to the mounting base 2 by screws 106. The PE terminal 102 and the signal terminal 103 are respectively disposed at both ends of the signal bracket 101. The outer surface of the PE terminal 102 is sleeved with the first circular ring 104, and the outer surface of the signal terminal 103 is sleeved with the second circular ring 105. The PE terminal 102 is a metal connection used for grounding protection. The components include the signal terminal 103, which is a conductive connection component used to transmit electrical signals. It is typically used in circuits at the signal level, such as low-voltage control, current detection, and data transmission. Meanwhile, the first annular ring 104 and the second annular ring 10 are both sealing elements with elasticity and circular cross-section. They mainly use rubber sealing rings and are widely used in mechanical and electrical connection structures to fill the gaps between the connectors. They achieve waterproof, dustproof, and gas leakage prevention sealing functions through compression deformation. The signal bracket 101 is a support structure used to support the PE terminal and the signal terminal. The mounting base 2 has a signal hole 201 and a PE hole 203 respectively. The signal hole 201 is fixedly connected to the signal terminal 103. The PE hole 203 is located below the signal hole 201 and is fixedly connected to the PE terminal 102. A screw hole 202 is provided between the signal hole 201 and the PE hole 203, and the screw 106 is threadedly connected to the screw hole 202. The signal hole 201 is a fixed mounting structure for receiving the signal terminal 103 and forming an electrical connection with it, and the PE hole 203 is a fixed mounting structure for receiving the PE terminal 102 and forming an electrical connection with it.
[0021] refer to Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the signal bracket 101 has a screw through hole 101c, and the screw through hole 101c is threadedly connected to the screw 106. The end of the signal bracket 101 away from the screw through hole 101c has a PE slot 101a. The outer surface of the PE terminal 102 has a PE slot 102a, and the PE terminal 102 is engaged with the PE slot 101a through the PE slot 102a.
[0022] During installation, the first ring 104 is manually fitted onto the outer surface of the PE terminal 102. Then, the end of the PE terminal 102 without the first ring 104 is manually inserted into the PE slot 101a of the signal bracket 101. This allows the PE terminal 102 to be secured in the PE slot 101a via the PE slot 102a. Simultaneously, when the PE terminal 102 is inserted into the PE slot 101a, it causes the first ring 104 to contact the PE slot 101a for sealing and waterproofing.
[0023] refer to Figures 1-9 As shown, the signal bracket 101 has a signal slot 101b at one end near the screw through hole 101c, and the signal terminal 103 has a signal slot 103a on its outer surface. The signal terminal 103 is engaged with the inside of the signal slot 101b through the signal slot 103a. The mounting base 2 has a mounting groove 204 inside, and the signal component 1 is disposed inside the mounting groove 204.
[0024] After installing the PE terminal 102 as described above, manually fit the second ring 105 onto the outer surface of the signal terminal 103. Then, manually insert the end of the signal terminal 103 without the second ring 105 into the signal slot 101b of the signal bracket 101. This allows the signal terminal 103 to be secured in the signal slot 101b via the signal slot 103a. Simultaneously, when the signal terminal 103 is inserted into the signal slot 101b, the signal terminal 103 causes the second ring 105 to contact the signal slot 101b for sealing and waterproofing. It should be noted that there is no specific installation order for PE terminal 102 and signal terminal 103; the installation order can be chosen by the user. After PE terminal 102 and signal terminal 103 are installed on signal bracket 101, manually place signal bracket 101 with PE terminal 102 and signal terminal 103 into mounting slot 204 of mounting base 2. This allows signal bracket 101 to drive PE terminal 102 and signal terminal 103 into PE hole 203 and signal hole 201 respectively for fixation. Then, signal bracket 101 aligns screw through hole 101c with screw hole 202 of mounting base 2, making the screw through hole 101c connected to the screw hole 202 of mounting base 2. Finally, manually screw screw 106 into screw hole 202 from screw through hole 101c, thus fixing signal bracket 101 to mounting base 2 via screw 106.
[0025] refer to Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the signal slot 103a and the PE slot 102a are horizontally snap-fit structures. The signal slot 103a is a slot structure set on the outer surface of the signal terminal 103, and the PE slot 102a is a slot structure set on the outer surface of the PE terminal 102.
[0026] When the signal terminal 103 and PE terminal 102 are inserted into the signal bracket 101 through the signal slot 103a and PE slot 102a respectively, the signal terminal 103 and PE terminal 102 are inserted into the signal bracket 101 in the lateral direction. The signal slot 103a and PE slot 102a both adopt a slot structure. The signal terminal 103 and PE terminal 102 are respectively engaged with the signal slot slot 101b and PE slot 101a through the slot structure of the signal slot 103a and PE slot 102a, so that the signal terminal 103 and PE terminal are stably assembled and positioned with the signal bracket 101 respectively.
[0027] refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the signal hole 201 and the PE hole 203 are connected to the signal slot 101b and the PE slot 101a, respectively.
[0028] When the signal bracket 101 with PE terminal 102 and signal terminal 103 is placed in the mounting slot 204 of the mounting base 2, the signal hole 201 and PE hole 203 need to be connected to the signal slot 101b and PE slot 101a respectively, so that the signal terminal 103 inside the signal slot 101b and the PE terminal inside the PE slot 101a can be inserted into the signal hole 201 and PE hole 203 respectively for fixed installation. Through this pre-positioned connection structure, a modular docking method is realized for assembly and fixation, which improves assembly efficiency and positioning accuracy.
[0029] Working principle: During installation, manually fit the first ring 104 onto the outer surface of the PE terminal 102. Then, manually insert the end of the PE terminal 102 without the first ring 104 into the PE slot 101a of the signal bracket 101. Next, manually fit the second ring 105 onto the outer surface of the signal terminal 103. Then, manually insert the end of the signal terminal 103 without the second ring 105 into the signal slot 101b of the signal bracket 101. After the PE terminal 102 and signal terminal 103 are installed on the signal bracket 101, manually attach the PE terminal... The signal bracket 101 of the PE terminal 102 and the signal terminal 103 is placed in the mounting groove 204 of the mounting base 2, so that the signal bracket 101 drives the PE terminal 102 and the signal terminal 103 to be inserted into the PE hole 203 and the signal hole 201 respectively for fixation. Then, the signal bracket 101 drives the screw through hole 101c to align with the screw hole 202 of the mounting base 2, so that the screw through hole 101c is connected to the screw hole 202 of the mounting base 2. Then, the screw 106 is manually screwed into the screw hole 202 from the screw through hole 101c, so that the signal bracket 101 is fixedly connected to the mounting base 2 by the screw 106. When the signal bracket 101 with PE terminal 102 and signal terminal 103 is placed in the mounting slot 204 of the mounting base 2, the signal hole 201 and PE hole 203 need to be connected to the signal slot 101b and PE slot 101a respectively, so that the signal terminal 103 inside the signal slot 101b and the PE terminal inside the PE slot 101a can be inserted into the signal hole 201 and PE hole 203 respectively for fixed installation.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
