Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings. Figures 1-2 As shown, this utility model is a protective housing structure for a bidirectional DC / DC shared manager, including a housing 1, a protective cover 6, and a buffer buckle 10. The housing 1 has fixing plates 9 on both sides, which are fixed to designated positions by screws. The housing 1 includes an upper cover 1-1 and a bottom plate 1-2. The upper cover 1-1 is fixedly connected to the bottom plate 1-2. An extension plate 1-3 is connected to the rear end of the bottom plate 1-2. The front end of the upper cover 1-1 is an insertion port for the bidirectional DC power module 2, and the rear end of the upper cover 1-1 is fixedly connected to a backplate terminal block 3. The protective cover 6 is mounted on the extension plate 1-3. The rear wall of the protective cover has a grid-like heat dissipation structure. A through groove 11 is formed on the upper wall of the upper cover 1-1. The length and width of the through groove 11 are determined by the dimensions of the buffer buckle 10, which can pass through the through groove 11. Limiting plates 12 are provided on both sides of the through groove on the inner wall of the upper cover 1-1. A movable screw 8 is provided between the two limiting plates 12, and the guide groove of the buffer buckle 10 is slidably connected to the movable screw 8.

[0027] like Figure 3 As shown, one or more baffles 7 are evenly arranged inside the upper cover 1-1. The number of baffles 7 is determined by the bidirectional DC power module 2. The baffles 7 divide the interior of the upper cover 1-1 into multiple independent spaces. Each independent space has a through slot 11 at the corresponding position of the upper cover.

[0028] like Figure 4 As shown, it also includes a copper busbar 5. The copper plate 5 includes a positive copper busbar and a negative copper busbar. The back plate terminal 3 is connected to two sets of wires. One set of wires leads the terminal to the positive copper busbar and the negative copper busbar respectively. The other set of wires leads the terminal to the extension plate for fixing, serving as an extension terminal 4. The extension terminal 4 is provided with a transparent protective plate. The protective cover 6 is fitted on the back plate terminal 3, the wires and the copper busbar 5.

[0029] Specifically, as shown in Figure 5 The buffering buckle 10 is a convex plate provided with a right trapezoidal protruding portion 10-4, the inclined surface 10-1 of the buffering buckle protruding portion 10-4 is in sliding connection with the bidirectional DC power module 2, a guide sliding groove is formed in the buffering buckle 10, the guide sliding groove is an obtuse angle sliding groove composed of a vertical segment 10-2 and an inclined segment 10-3, the vertical segment 10-2 is close to the protruding portion 10-4, the upper end of the vertical segment 10-2 is in communication with the inclined segment 10-3, and the inclined direction of the inclined segment 10-3 is opposite to the inclined direction of the inclined surface 10-1 of the buffering buckle protruding portion 10-4.

[0030] When the bidirectional DC power module 2 is installed, the bidirectional DC power module 2 enters the shell from the upper cover front segment, when the bidirectional DC power module 2 is not inserted, the buffering buckle 10 is hung in the shell through the movable screw 8, at this time, the movable screw 8 is located at the upper end of the sliding groove inclined segment 10-3, the bidirectional DC power module 2 is manually inserted into the shell, as shown in Figure 6 The end of the bidirectional DC power module 2 first contacts the inclined surface 10-1 of the buffering buckle protruding portion 10-4, the movable screw 8 slides in the sliding groove inclined segment 10-3, when the bidirectional DC power module 2 slides to the end of the inclined surface 10-1, as shown in Figure 7 The movable screw 8 is clamped at the joint of the inclined segment 10-3 and the vertical segment 10-2, and the buffering buckle 10 protrudes from the upper cover 1-1, at this time, the gold finger 2-1 at the end of the bidirectional DC power module 2 slightly contacts the back plate wiring terminal 3, which plays a buffering role for the charging of the bidirectional DC power module 2 and achieves the purpose of pre-charging. Figure 8 As shown in The movable screw 8 slides in the vertical segment 10-2 until it is clamped at the lower end of the vertical segment 10-2, at this time, the bidirectional DC power module 2 is continuously pushed, so that the gold finger 2-1 is in complete contact with the back plate wiring terminal 3, thereby avoiding the phenomenon that a great instantaneous voltage difference (or current difference) is generated due to the moment of combination, which causes the equipment to appear a sparking phenomenon, resulting in damage to the equipment and even causing a fire hazard.

[0031] Since the back plate wiring terminal 3 is led out to the extended wiring terminal 4, and the extended wiring terminal 4 is provided with a transparent protective plate, the wiring terminal is convenient to use while ensuring the safety of use.
