DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] An embodiment of a power battery connector of the present invention is as follows Figures 1 to 10 shown.

[0031] A power battery connector includes a male connector 110, a female connector 120 and a locking member, wherein the male connector 110 can move along a first direction and be plugged into the female connector 120, wherein the first direction is a horizontal direction, and the locking member is used to lock the plugged male connector 110 and the female connector 120 to prevent the male connector 110 from being loosened from the female connector 120. The locking member includes a locking bracket 140, a locking plate 130 and a connecting member.

[0032] The locking bracket 140 can be installed on the female head 120 so as to rotate around a second direction, the second direction is horizontal and perpendicular to the first direction, and the positive rotation of the locking bracket 140 around the second direction can increase the locking force between the male head 110 and the female head 120, the locking plate 130 can be installed on the female head 120 so as to rotate around the second direction, and the reverse rotation of the locking plate 130 around the second direction can increase the locking force between the male head 110 and the female head 120; the connecting piece can connect the locking bracket 140 that rotates around the second direction and the locking plate 130 that rotates around the second direction.

[0033] Specifically, guide posts 111 are provided on both sides of the male connector 110 along the third direction, the third direction is a vertical direction, the guide posts 111 are provided along the first direction, and guide grooves 121 are provided on the female connector 120. The guide posts 111 can slide along the first direction and be inserted into the corresponding guide grooves 121. More specifically, four guide posts 111 are provided, and every two guide posts 111 are on the same side along the third direction on the male connector 110, and the two guide posts 111 on the same side along the third direction are spaced apart along the second direction.

[0034] This embodiment is provided with a male head 110, a female head 120 and a locking member. When in use, after the male head 110 and the female head 120 are plugged in, the operator manually rotates the locking plate 130 and the locking bracket 140, and makes the locking bracket 140 rotate forwardly around the second direction, and uses the locking bracket 140 to rotate forwardly around the second direction to increase the locking force between the male head 110 and the female head 120, and then makes the locking plate 130 rotate backwardly around the second direction, and uses the locking plate 130 to rotate backwardly around the second direction to further increase the locking force between the male head 110 and the female head 120, and uses a connecting member to connect the forward rotating locking bracket 140 and the reverse rotating locking plate 130, and lock the locking bracket 140 and the locking plate 130. It should be particularly noted that the forward direction mentioned in this embodiment refers to the attached Figure 1 The clockwise direction is from right to left in the figure. For the reverse direction, please refer to the attached Figure 1 Counterclockwise when looking from right to left.

[0035] After the male head 110 and the female head 120 are locked by the connecting piece, if the locking bracket 140 rotates in the opposite direction around the second direction during use, the male head 110 and the female head 120 will tend to loosen. However, when the locking bracket 140 rotates in the opposite direction around the second direction, the locking plate 130 will be driven to rotate in the opposite direction synchronously under the action of the connecting piece, and the reverse rotation of the locking plate 130 will increase the locking force between the male head 110 and the female head 120, thereby limiting the loosening of the male head 110 and the female head 120. Similarly, if the locking plate 130 rotates in the forward direction around the second direction, thereby promoting However, when the locking plate 130 rotates forwardly around the second direction, the locking bracket 140 will be driven to rotate forwardly synchronously under the action of the connecting piece, and the forward rotation of the locking bracket 140 will increase the locking force between the male head 110 and the female head 120, which also limits the loosening of the male head 110 and the female head 120. The locking plate 130 and the locking bracket 140 are interlocked by the connecting piece. After the locking plate 130 and the locking bracket 140 lock the plugged male head 110 and the female head 120, the male head 110 and the female head 120 are prevented from loosening.

[0036] The double locking design of the locking bracket 140 and the locking plate 130, combined with the interlocking effect of the connector between the locking plate 130 and the locking bracket 140, does not require excessive insertion force to achieve normal plugging, and can effectively prevent loosening, avoid loosening and poor contact in a vibration environment, and effectively ensure the normal use of the connector function. When the male head 110 and the female head 120 need to be separated, first release the connection between the locking plate 130 and the locking bracket 140 by the connector, then rotate the locking bracket 140 in the opposite direction, and then rotate the locking plate 130 forward, and finally pull out the male head 110 without using excessive pull-out force, which can prevent the operator from losing balance due to inertia.

[0037] In this embodiment, the male head 110 is respectively provided with an insertion rod 112 at both ends along the second direction, and the insertion rod 112 is arranged along the second direction. The locking bracket 140 includes a rotating frame 141 and two locking heads 142. The two locking heads 142 are respectively arranged at the two ends of the rotating frame 141 along the second direction. The locking head 142 can be installed on the female head 120 rotatably around the second direction. A notch 143 is provided on the locking head 142. The notch 143 has a head end and a tail end. The head end extends to the tail end in the opposite direction of the second direction. The male head 110 moves toward one side of the female head 120 along the first direction, so that the insertion rod 112 can slide to the head end of the notch 143, and when the locking head 142 rotates around the second direction, the insertion rod 112 can move from the head end of the notch 143 to the tail end of the notch 143.

[0038] Specifically, two first connecting shafts 123 are arranged on the female head 120, and the two first connecting shafts 123 are arranged along the second direction. The two locking heads 142 are rotatably connected to the two first connecting shafts 123. A through slot 122 is provided on the female head 120, and the male head 110 moves toward one side of the female head 120 along the first direction, so that the insertion rod 112 can slide in the through slot 122.

[0039] Furthermore, the area of ​​the notch 143 gradually decreases from the head end to the tail end thereof, and the locking head 142 is made of elastic material.

[0040] In this embodiment, the locking head 142 and the insertion rod 112 are matched. After the insertion rod 112 is matched with the notch 143 of the locking head 142, the operator manually rotates the locking bracket 140 to make the locking bracket 140 rotate positively around the second direction, thereby moving the insertion rod 112 from the head end of the notch 143 to the tail end of the notch 143, and further pulling the male head 110 to move toward the female head 120 along the first direction. For details, see the attached Figure 6 and attached Figure 7 , increasing the locking force between the male head 110 and the female head 120, and because the area from the head end to the tail end of the notch 143 gradually decreases, the internal space of the notch 143 will be squeezed by the insertion rod 112, ensuring the tight connection between the insertion rod 112 and the notch 143, and preventing the locking head 142 and the insertion rod 112 from loosening due to vibration or other situations.

[0041] In this embodiment, the locking plate 130 includes a rotating shaft 131 and a plate body 132. The two ends of the rotating shaft 131 along the second direction are respectively mounted on the female head 120 so as to be rotatable around the second direction. The plate body 132 is fixed to the rotating shaft 131 and rotates with the rotating shaft 131. The rotating shaft 131 is made of elastic material and is eccentrically arranged on the female head 120. In the initial state when the male head 110 is plugged into the female head 120, the shaft hole of the rotating shaft 131 is located on the side close to the surface of the female head 120 along the third direction and does not contact the surface of the male head 110. When the rotating shaft 131 rotates in the opposite direction around the second direction, the shaft hole of the rotating shaft 131 will rotate to the side away from the surface of the female head 120 along the third direction, and the rotating shaft 131 can contact the surface of the male head 110.

[0042] Specifically, two second connecting shafts 124 are disposed on the female connector 120 , and the two second connecting shafts 124 are both disposed along the second direction. Both ends of the rotating shaft 131 along the second direction are rotatably connected to the two second connecting shafts 124 .

[0043] In this embodiment, the locking plate 130 is provided, and the eccentric structure of the rotating shaft 131 enables the rotating shaft 131 to gradually contact the surface of the male head 110 when the locking plate 130 rotates in the opposite direction around the second direction, that is, Fig. 9 The status shown is turned to Fig.10 In the state shown, the locking force between the male connector 110 and the female connector 120 after being plugged in is increased.

[0044] In this embodiment, the connecting member includes a clamping block 133 . The clamping block 133 is disposed on the plate body 132 . A clamping slot 144 is formed on the rotating frame 141 . The clamping block 133 can be clamped with the clamping slot 144 .

[0045] In this embodiment, a clamping block 133 is provided on the plate body 132, a clamping slot 144 is opened on the rotating frame 141, and the clamping slot 144 is clamped with the clamping block 133 to connect the forward rotating locking bracket 140 and the reverse rotating locking plate 130, thereby locking the locking bracket 140 and the locking plate 130.

[0046] In combination with the above embodiments, the specific working process is as follows:

[0047] When in use, the operator holds the male head 110 and pushes the male head 110 along the first direction to move toward the female head 120 to plug the male head 110 with the female head 120, and at the same time, the insertion rod 112 slides along the first direction to the head end of the notch 143 synchronously with the male head 110. Then the operator manually rotates the locking bracket 140 to make the locking bracket 140 rotate positively around the second direction, thereby moving the insertion rod 112 from the head end of the notch 143 to the tail end of the notch 143, and the male head 110 can be further pulled to move along the first direction toward the female head 120. For details, see the attached Figure 6 and attached Figure 7 , increasing the locking force between the male head 110 and the female head 120, and because the area from the head end to the tail end of the notch 143 gradually decreases, the internal space of the notch 143 will be squeezed by the insertion rod 112, preventing the locking head 142 and the insertion rod 112 from loosening due to vibration or other situations.

[0048] Then, the locking plate 130 is rotated in the opposite direction around the second direction. When the locking plate 130 is rotated in the opposite direction around the second direction, the rotating shaft 131 can gradually contact the surface of the male head 110, that is, Fig. 9 The status shown is turned to Fig.10 In the state shown, the locking force between the male connector 110 and the female connector 120 after plugging is increased. Then, the card slot 144 is engaged with the card block 133, and the forward rotating locking bracket 140 is connected with the reverse rotating locking plate 130, thereby locking the locking bracket 140 and the locking plate 130.

[0049] The double locking design of the locking bracket 140 and the locking plate 130, combined with the interlocking effect of the card block 133 and the card slot 144 between the locking plate 130 and the locking bracket 140, does not require excessive insertion force to achieve normal plugging, and can effectively prevent loosening, avoid loosening and poor contact under a vibration environment, and effectively ensure the normal use of the connector function. When the male head 110 and the female head 120 need to be separated, the connection between the locking plate 130 and the locking bracket 140 by the connecting member is first released, and then the locking bracket 140 is rotated in the opposite direction, and then the locking plate 130 is rotated forward. In the process of the locking bracket 140 rotating in the opposite direction, a component force will be generated between the insertion rod 112 and the locking head 142 to separate the inner bottom wall surface of the male head 110 and the inner bottom wall surface of the female head 120 from each other, which facilitates the loosening of the male head 110 and the female head 120. Finally, the male connector 110 can be pulled out without using excessive pulling force, which can prevent the operator from losing balance due to inertia.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
