[0030] The following combines specific embodiments to further elaborate on the content of the present utility model:

[0031] For the convenience of understanding, first, the application scenario of the present utility model is described. This application is used for the electrical connection of energy storage power sources and electrical cabinets in the automotive field. Refer to the attached Figure 1 , one end of the energy storage connector with pins is the plug, and usually the other end is the socket. The plug and the socket are mated to achieve electrical connection. However, due to limitations in the operating space during actual use, especially when one end of the socket or the plug is installed inside the distribution box / power supply box, and the plug or the socket is inside or outside the distribution box / power supply box, for blind mating, it is not convenient to mate the plug and the socket. Therefore, it is necessary to ensure the safety of the operator and be able to quickly mate the connector to improve the operation agility.

[0032] As Figure 1 shown, an energy storage connector includes an upper cover 1, a base 2, and a pin 3. The upper cover 1 is internally provided with a cavity 11. The upper cover 1 is buckled with the base 2 and maintained in the buckled state by a locking component 5.

[0033] Refer to the attached Figure 2, on the inner end face 24 of the base 2, a pair of oppositely arranged baffles 4 accommodated in the cavity 11 are connected. The space between the two baffles 4 is the terminal docking area 42. The pin 3 is vertically assembled in the terminal docking area 42 through the through hole 21 on the base 2.

[0034] Combined with the attached Figure 1 and the attached Figure 4 , on the upper cover 1, a pair of terminal assembly windows 12 are provided for the mating conductive parts to be inserted into the terminal docking area 42 to make electrical connection with the pin 3. The terminal assembly windows 12 are located in the free port intervals on both sides of the docking area.

[0035] The upper cover 1 is snapped to cover the internal terminal docking area 42, isolating the energized metal pin 3 to prevent personnel from contacting, protecting personnel safety, dustproof and splash-proof, preventing mechanical failures, increasing mechanical life, and improving the overall reliability of the device.

[0036] The pin 3 is provided with screw connection holes. The mating conductive part can be connected in contact in the way of a copper bar or connected in and out in the way of a copper nose pressing the wire. The connector has stronger compatibility.

[0037] As shown in the attached Figure 5 , the head of the pin 3 is in the terminal docking area 42, the tail of the pin 3 remains on one side of the outer end face 25 of the base 2. The main body of the pin 3 is supported and fixed by the support column 6. The support column 6 is cylindrical and is hollowed out inside to form a tubular frame shape. The pin 3 passes through and is inserted into the installation hole in the middle of the support column 6, and a pair of elastic clip fasteners 7 are arranged in the hollow spaces on both sides of the installation hole. The elastic clip fasteners 7 are made of insulating materials. The two elastic clip fasteners 7 are in an overall shape of an eight-character, with a small opening angle at the top and converging towards the middle to clamp and limit the main body side wall of the pin 3.

[0038] As shown in the attached Figure 6 and the attached Figure 3 As shown in the attached

[0039] , the baffle 4 is made of insulating material and a distance is reserved between it and the outer edge of the through hole 21. Both the base 2 and the upper cover 1 are made of insulating materials and are injection-molded. Multiple grooves are provided on the surfaces of the inner end face and the outer end face of the base 2, forming a concave-convex grid surface.

[0040] By setting the outer end face 25 and the inner end face of the injection-molded base 2 carrying electrical docking as a hollowed-out grid shape, with a baffle 4 on one side and a circular stop post 8 on the other side, the creepage distance is increased and the withstand voltage value is improved. The exposed length of the pin 3 for electrical connection is less than that of a conventional metal terminal, reducing the product volume.

[0041] Refer to the attachedFigure 4 , a set of opposite side plates 13 of the upper cover 1 are recessed inward, and the outer wall surface of the recessed side plate 13 and the plate surfaces on both sides enclose a receiving groove 14, and the receiving groove 14 provides an activity space for the locking component 5 to be engaged and disengaged.

[0042] Specifically, the locking component 5 includes several grooves 53 provided on the inner wall of the side plate 13 (located in the cavity 11) and elastic buckles 51. The elastic buckles 51 on both sides open outward, presenting an overall shape of an inverted V; the elastic buckles 51 are integrally formed with the side plate 13 and are juxtaposed and stacked in the receiving groove 14 outside the side plate 13, and buckling teeth 52 are provided on the outer wall of the elastic buckles 51; a pair of hanging ears 22 are provided on the base 2, the length of the hanging ears 22 is less than the length of the baffle 4, the hanging ears 22 are integrally U-shaped, and hanging ridges 23 are provided on the inner wall of the U-shaped cavity.

[0043] Refer to the appendix Figure 1 Combined with the appendix Figure 5 , during mating installation, hold the elastic buckles 51 on both sides and buckle the upper cover 1 on the base 2. Correspondingly, the elastic buckles 51 are inserted into the U-shaped hanging ears 22, and the buckling teeth 52 cooperate with the hanging ridges 23 to lock the buckling state. The insertion and buckling as well as the pulling out and separating operations are simple, and the operation efficiency is higher. Among them, a partition strip 41 that cooperates with the strip grooves 53 is provided on the side wall of the baffle 4, which can play a guiding and limiting role when the upper cover 1 and the base 2 are inserted into each other.
