Description

TECHNICAL FIELD

[0001] The utility model discloses a mistaken touch protection mechanism of charging gun and charging socket connector assembly. BACKGROUND

[0002] The charging connector assembly of the new energy vehicle usually comprises a charging socket arranged on a vehicle body and a charging gun matched with the charging socket, a plurality of hollow insertion columns with insertion holes opened at front ends are fixed on the inner side panel of the head of the charging gun, female terminals are arranged in the hollow insertion columns, a plurality of male terminals are arranged on the charging socket corresponding to the female terminals, and when the charging gun and the shell of the charging socket are connected and matched, the male terminals are inserted into the hollow insertion columns and are in contact with and conduct electricity with the female terminals.

DETAILED DESCRIPTION

[0048] Example 1: in combination Figures 1-11 As shown, a specific embodiment of the anti-mis-touch protection mechanism of the charging gun and charging socket connector assembly provided by the utility model is described in detail as follows:

[0049] First, in combination Figure 1 And Figure 2 As shown, like conventional technology, it has a charging gun 1 and a charging socket 2, the charging gun 1 has a gun head 101 and a hollow plug post 102 with four front end plug holes 102a, the hollow plug post 102 is internally provided with a female terminal 3, and the charging socket 2 is provided with a male terminal 4 corresponding to the female terminal 3.

[0050] The core improvement of the utility model lies in that the plug hole 102a at the front end of each hollow plug post 102 is installed with a rotating locking mechanism, and the rotating locking mechanism is composed of a protective cap 5, a rotation shaft 6, three rotating baffles 7 and a torsional spring 9. In combination Figures 3-7As shown, the protective cap 5 is fixed to the front end of the hollow insertion column 102, and a through hole 501 is formed in the front wall of the protective cap 5 opposite to the insertion hole 102a. Three hollow grooves 502 are circumferentially arranged on the protective cap 5, and each of the hollow grooves 502 is provided with a rotating baffle 7 rotatable around a rotating shaft 6 and a torsion spring 9 sleeved on the rotating shaft 6 for resisting the rotation of the rotating baffle 7. The rotating baffle 7 is folded and closed in the through hole 501 to shield the insertion hole 102a under the elastic force of the torsion spring 9. Each rotating baffle 7 has a stress receiving portion 701 protruding outside the hollow groove 502. As shown in Figure 10 and Figure 11 As shown, the hollow grooves 502 are equally spaced circumferentially on the protective cap 5, and the rotating baffles 7 are centrally symmetrically distributed with the center of the through hole 501 as the symmetric center.

[0051] As shown in Figure 1 and Figure 2 Each trigger mechanism is a top pipe 8 arranged on the periphery of the corresponding male terminal 4, and the top pipe 8 is opposite to the stress receiving portion 701 of all the rotating baffles 7 of the corresponding rotating locking mechanism, and is used to provide a pushing force to the stress receiving portion 701 to rotate the rotating baffles 7 to disperse each other to form an avoiding position for the male terminal 4 to be inserted into the insertion hole 102a, as shown in Figure 12 and Figure 13 As shown.

[0052] As shown in Figures 6-9 The rotating baffle 7 is provided with a positioning recess 702 corresponding to each torsion spring 9 for accommodating the torsion spring 9, one end of the torsion spring 9 is arranged on the inner wall of the positioning recess 702, and the protective cap 5 is provided with a stepped groove 503 corresponding to each positioning recess 702 for accommodating the other end of the torsion spring 9.

[0053] As shown in Figure 8 The stress receiving portion 701 of the rotating baffle 7 is provided with a slope 701a for bearing the pushing force of the top pipe 8, which facilitates the conversion of the pushing force of the top pipe 8 into the extrusion force for driving the rotating baffle 7 to rotate, and makes the process more smooth.

[0054] As shown in Figures 3-6 The insertion hole 102a of the hollow insertion column 102 is formed with four radially inward protruding clamping blocks 102b, and the rear end of the protective cap 5 extends four connecting spring sheets 504 corresponding to the clamping blocks 102b, and the connecting spring sheet 504 is provided with a clamping hole 504a for clamping the clamping block 102b.

[0055] As shown in Figure 3 and Figure 4As shown, the hollow insertion column 102 of the embodiment is distributed with insertion column shaft positioning holes 102c on the periphery of the end surface of the insertion hole 102a for inserting and fixing the shaft 6, and the protective cap 5 is provided with a hollow groove shaft positioning hole 505 opposite the shaft positioning hole 102c for the shaft 6 to pass through the hollow groove 502. In actual assembly, one end of the shaft 6 is fixed in the insertion column shaft positioning hole 102c, and the other end is inserted into the hollow groove 502 through the hollow groove shaft positioning hole 505 and penetrates through the rotating baffle 7, thereby completing the rotating assembly of the rotating baffle 7.

[0056] As shown in Figure 1 , Figure 10 and Figure 11 , when the charging gun 1 and the charging socket 2 are not connected, each rotating locking mechanism on the charging gun 1 is in a locked state, which is specifically manifested as that each rotating baffle 7 is folded and closed in the through hole 501 under the elastic force of the torsional spring 9 to shield the insertion hole 102a, so that the male terminal 4 on the charging socket 2 cannot be inserted into the hollow insertion column 102 to cooperate with the female terminal 3.

[0057] As shown in Figure 2 , Figure 12 and Figure 13 , when the charging gun 1 and the charging socket 2 are connected, each rotating locking mechanism on the charging gun 1 is in an open state, which is specifically manifested as that the top pipe 8 around the corresponding female terminal 3 on the charging socket 2 is opposite to the stress part 701 on all rotating baffles 7 of the corresponding rotating locking mechanism, thereby providing a pushing force to the stress part 701 to make the rotating baffles 7 rotate and spread apart each other to overcome the elastic force of the torsional spring 9, thereby forming an avoiding position for the male terminal 4 to be inserted into the insertion hole 102a, so that the male terminal 4 cooperates with the female terminal 3.

[0058] Embodiment 2: further combined with Figures 14-19 As shown in another specific embodiment of the anti-mis-touch protection mechanism of the charging gun and charging socket plug-in assembly of the utility model, the overall structure is basically the same as that of embodiment 1, the difference lies in the structural change of the protective cap 5, the rotating baffle 7 and the elastic element, which will be described in detail below:

[0059] As shown in Figure 14 , the embodiment also has a charging gun 1 and a charging socket 2, the charging gun 1 has a gun head 101 and four hollow insertion columns 102 provided with insertion holes 102a at the front ends, the hollow insertion column 102 is internally provided with a female terminal 3, and the charging socket 2 is provided with a male terminal 4 corresponding to the female terminal 3. Each insertion hole 102a at the front end of each hollow insertion column 102 is provided with a rotating locking mechanism, and the rotating locking mechanism is composed of a protective cap 5, a shaft 6, three rotating baffles 7 and a special-shaped spring 10.

[0060] Further combined with Figure 15And Figure 16 As shown in the drawings, the protective cap 5 in this embodiment is of split structure, which is connected by a front cap 5A and a rear cap 5B, and the cap 5A is provided with a through hole 501 opposite to the insertion hole 102a. The cap 5A is uniformly and equidistantly provided with three connecting arms 11 extending to the rear end with a reverse buckle 11a on the circumference, while the cap 5B is provided with a buckle groove 12 on the outer circumference for fixing the reverse buckle 11a on each connecting arm 11. After the cap 5A is connected to the cap 5B, a gap is left between the cap 5A and the front end wall of the cap 5B, which is equally divided into three hollow grooves 502 by the three connecting arms 11 (see Figure 3 And Figure 5 As shown in the drawings). The front end wall of the cap 5B is uniformly and equidistantly fixed with three rotating shafts 6 on the circumference, which respectively extend into the three hollow grooves 502 for assembling the corresponding rotating baffle 7.

[0061] In this embodiment, the cap 5A is also uniformly and equidistantly provided with three support arms 13 extending to the rear end on the circumference for abutting against the front end wall of the cap 5B to improve the support force of the cap 5A. Although the hollow grooves 502 are further divided by the support arms 13, the support arms 13 do not interfere with the rotation of the rotating baffle 7 because the rotating range of the rotating baffle 7 in the hollow groove 502 is very small.

[0062] Like the first embodiment, the inner wall of the insertion hole 102a of the hollow insertion column 102 is shaped with four radially inward protruding clamping blocks 102b, and the rear end of the cap 5B of the protective cap 5 extends four connecting springs 504 corresponding to the clamping blocks 102b, which are provided with clamping holes 504a for clamping the clamping blocks 102b.

[0063] Further combining Figure 17 And 18 As shown in the drawings, the elastic element for resisting the rotation of the rotating baffle 7 in this embodiment is a special-shaped spring 10, which is a section of spring rod, one end of which is bent and directly injection molded and fixed on the rotating baffle 7, and the other end is bent and clamped in the protective cap clamping groove 506 provided on the end face of the cap 5B. Like the working principle of the torsion spring 9 in the first embodiment, these rotating baffles 7 are folded and closed in the through hole 501 to block the insertion hole 102a under the elastic force of the special-shaped spring 10, and each rotating baffle 7 has a stress receiving portion 701 protruding outside the hollow groove 502, which is provided with a slope 701a for bearing the thrust of the outer peripheral tube 8 of the male terminal 4. Figure 1 And Figure 2 The slope 701a bears the thrust of the outer peripheral tube 8 of the male terminal 4.

[0064] Further combining Figure 19As shown, the three rotating baffles 7 in the embodiment are centrally symmetrically distributed with the center of the through hole 501 as the symmetric center. When the rotating baffles 7 are closed, the heads of the rotating baffles 7 are sequentially attached along the circumference; and the head of each rotating baffle 7 is provided with an arc-shaped convex part 703 and an inner recessed part 704 matched with the arc-shaped convex part 703. When the rotating baffles 7 are closed, the arc-shaped convex part 703 on each rotating baffle 7 cooperates with the inner recessed part 704 on the adjacent rotating baffle 7, and the inner recessed part 704 on each rotating baffle 7 cooperates with the arc-shaped convex part 703 on the adjacent rotating baffle 7. The structural design ensures that the protection against external force invasion when the rotating baffles 7 are closed can be increased.

[0065] The remaining structure and working principle in the embodiment can be referred to the embodiment 1.

[0066] Of course, the above is only a specific application example of the utility model, and does not constitute any limitation on the protection scope of the utility model. In addition to the above embodiments, the utility model can also have other implementation manners. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the utility model claimed.
