Description

Technical Field

[0001] This utility model relates to a charging socket, and more particularly to a back cover for a charging socket. Background Technology

[0002] Currently, the wiring harness of electric vehicle charging sockets exits from the side, meaning the wiring harness runs perpendicular to the axis of the socket terminals.

[0003] For example, Chinese patent document CN222735407U discloses a side-outlet DC charging socket. The insulator mounts power contacts, socket contacts, and a circuit board. The back cover houses a pressure plate, which fixes the power contacts, socket contacts, and circuit board. When disassembling or repairing the circuit board, the back cover, along with the pressure plate and power contacts (power terminals), must be disassembled beforehand to perform the disassembly or repair work. The disassembly and repair work is cumbersome.

[0004] For example, Chinese patent document CN219739477U discloses a side-outlet charging socket. The insulator is used to install contacts and a circuit board. The tail cover houses the pressure plate. The contacts are fixed in the insulator, and the pressure plate fixes the circuit board. When disassembling or repairing the circuit board, the tail cover (back cover) and the pressure plate must be disassembled and repaired beforehand, which makes the disassembly and repair work cumbersome. Summary of the Invention

[0005] In order to overcome the cumbersome disassembly and assembly work caused by the pressure plate in the existing technology, this utility model proposes a charging socket side cable outlet back cover that can fix the circuit board and terminals by using only a back cover to simplify the disassembly and assembly work.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a charging socket side cable outlet cover, comprising a base plate and a front peripheral wall and a rear peripheral wall extending from the base plate, the base plate having a pair of shaft holes for passing through power terminals, the side of the rear peripheral wall being connected to a pair of cylinders for passing through power cable harness assemblies, the inner wall of the shaft holes extending with multiple elastic petals that can be snapped into power terminals, and the edge of the shaft holes extending with an arc-shaped plate for abutting against the circuit board and located on the front side of the base plate.

[0007] Furthermore, a pair of surrounding plates are provided on the back side of the substrate, the surrounding plates being located eccentrically at the shaft hole and symmetrical in the circumferential direction.

[0008] Furthermore, the front side of the substrate is provided with protrusions for abutting against signal terminals, and the front side of the substrate is also provided with protrusions for abutting against the circuit board.

[0009] Furthermore, a partition wall located at the center of the substrate is connected between the two enclosure panels.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a flap and an arc plate at the shaft hole of the back cover, the power terminal is fixed by using the flap to snap into the circular groove of the power terminal, and the circuit board is fixed by using the arc plate to abut against the circuit board. When the circuit board needs to be disassembled or assembled, only the back cover needs to be disassembled or assembled, which realizes a simplified and quick disassembly and assembly operation, improves the work tasks of quickly disassembling, assembling and repairing the circuit board. Furthermore, the flap replaces the limiting function of the insulator (front seat) of the prior art for the power terminal, and the back cover realizes the limiting function of the power terminal, which simplifies the structure of the front seat and reduces the manufacturing difficulty of the front seat.

[0018] To better understand the purpose, features, and advantages of this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further illustrate this utility model.

[0019] This utility model's charging socket side cable outlet cover is applied to DC charging sockets, and of course, it can also be applied to AC charging sockets.

[0020] Figure 1 and Figure 2 The illustration shows a DC charging socket containing the rear cover of this utility model. The DC charging socket mainly consists of a front base 1, a rear cover 2, power terminals 3, a power harness assembly 4, a grounding terminal 5, a grounding harness assembly 6, a window cover 7, a signal terminal 8, a circuit board 9, and a low-voltage connector.

[0021] like Figures 3 to 5As shown, the main body of the back cover 2 is composed of a base plate 2.1, a rear peripheral wall 2.2, a cylinder 2.3, and a front peripheral wall 2.4. The front peripheral wall 2.4 and the rear peripheral wall 2.2 extend from the front and back sides of the base plate 2.1, respectively. The base plate 2.1 has a pair of shaft holes 2.5 and a through hole 2.6. An arc-shaped plate 2.7 extends from the edge of the shaft hole 2.5, and three elastic lobes 2.8 extend from the inner wall of the shaft hole 2.5. The arc-shaped plate 2.7 is on the front side of the base plate 2.1, and the lobes 2.8 are inclined and within the circumference of the arc-shaped plate 2.7. The front side of the base plate 2.1 is provided with six protrusions 2.9 and four protrusions 2.10. A pair of surrounding plates 2.11 are provided on the back side of the substrate 2.1. The surrounding plates 2.11 are located eccentrically at the shaft hole 2.5. The two surrounding plates are symmetrical in the circumferential direction. A partition wall 2.12 is connected between the two surrounding plates 2.11. The partition wall 2.12 is approximately located at the center of the substrate 2.1. The side of the rear peripheral wall 2.2 is connected to two cylinders 2.3, and the other side of the rear peripheral wall 2.2 is connected to the circular hole 2.13.

[0022] like Figure 6 and Figure 7 As shown, the power terminal 3 passes through the shaft hole 2.5 of the rear cover 2. The power terminal 3 passes forward through the shaft hole 2.5, and the flap 2.8 is engaged in the annular groove 3.1 of the power terminal 3. The flap 2.8 abuts against the annular groove 3.1, preventing the power terminal 3 from retracting. The power harness assembly 4 passes through the cylinder 2.3 of the rear cover 2. The power terminal 3 is connected to the power harness assembly 4. The connection point between the power terminal 3 and the power harness assembly 4 falls within the enclosure 2.11. The enclosure facilitates guiding the connection end of the power harness assembly to the connection end of the power terminal. The partition wall 2.12 separates the two pairs of power harness assemblies 4 to prevent them from contacting and causing a short circuit. The grounding terminal 5 passes through the through hole 2.6 of the rear cover 2, and the grounding harness assembly 6 passes through the round hole 2.13. The connection point between the grounding terminal 5 and the grounding harness assembly 6 falls outside the enclosure. The front peripheral wall 2.4 of the rear cover 2 is fastened to the front seat 1, and the window cover 7 is fastened to the rear peripheral wall 2.2 of the rear cover 2 (as shown). Figure 1 The circuit board 9 is placed on the front of the substrate 2.1 of the back cover 2. The bump 2.9 abuts against the signal terminal 8, and the protrusion 2.10 and the arc plate 2.7 abut against the circuit board 9. After the back cover is assembled, the bump 2.9 fixes the signal terminal 8, and the protrusion 2.10 and the arc plate 2.7 fix the circuit board 9.
