DETAILED DESCRIPTION

[0023] 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.

[0024] An embodiment of a wiring harness connector structure for a new energy passenger vehicle of the present invention is as follows Figures 1 to 5 shown.

[0025] A wiring harness connector structure for a new energy passenger vehicle includes a male connector 100 and a female connector 200. The male connector 100 can move toward one side of the female connector 200 along a first direction and plug into the female connector 200. The plugging direction of the male connector 100 and the female connector 200 is referred to as the first direction. The male connector 100 includes a wiring harness body 110 and a contact piece 120. The contact piece 120 is elastic and made of metal. The contact piece 120 is mounted on the wiring harness body 110. In the initial state, the contact piece 120 is located on the side of the wiring harness body 110 close to the female connector 200 in the first direction.

[0026] The female connector 200 includes a housing 210, a clearance block 220 and a plurality of partitions 230. The clearance block 220 is arranged in the housing 210 around the first direction, and a crimping cavity is defined between the clearance block 220 and the housing 210. The plurality of partitions 230 are evenly distributed in the housing 210 around the first direction, and in the initial state, the partitions 230 are located on the side of the clearance block 220 close to the contact piece 120 in the first direction. A clearance space is defined between each two adjacent partitions 230 arranged around the first direction. A plurality of limit plates 130 are evenly distributed on the wiring harness body 110 around the first direction, and the limit plates 130, the partitions 230 and the clearance spaces are arranged one by one.

[0027] The wiring harness connector structure of new energy passenger vehicles has a first state and a second state. When in the first state, each limit plate 130 is located in the corresponding clearance space; when in the second state, one end of the limit plate 130 away from the clearance block 220 in the first direction abuts against the end of the partition plate 230 close to the clearance block 220 in the first direction.

[0028] In this embodiment, a contact piece 120 and a limit plate 130 are arranged on the wiring harness body 110, and a clearance block 220 and a partition 230 are arranged in the shell 210. When in use, the operator holds the wiring harness body 110, so that the limit plate 130 on the wiring harness body 110 enters the shell 210 from the clearance space corresponding to it, and the contact piece 120 comes to the crimping cavity between the clearance block 220 and the shell 210. At this time, the wiring harness connector structure of the new energy passenger car is in the first state, and the preliminary connection of the contact piece 120 is completed. Then, the wiring harness connector structure of the new energy passenger car is switched to the second state, so that the end of the limit plate 130 away from the clearance block 220 in the first direction is abutted against the end of the partition 230 close to the clearance block 220 in the first direction, and the limit plate 130 and the corresponding partition 230 are matched to lock the limit plate 130 and limit the contact piece 120, so that the contact piece 120 remains stable in the crimping cavity, prevents the contact piece 120 from falling out of the shell 210, and makes the connection more stable and reliable.

[0029] In this embodiment, the wire harness body 110 is rotatable about a first direction, and the rotation of the wire harness body 110 about the first direction can switch the wire harness connector structure of the new energy passenger vehicle from the first state to the second state.

[0030] When one end of the limit plate 130 away from the clearance block 220 in the first direction is coplanar with the end of the partition 230 close to the clearance block 220 in the first direction, rotate the wiring harness body 110. The rotation of the wiring harness body 110 will drive the limit plate 130 to rotate, so that the end of the limit plate 130 away from the clearance block 220 in the first direction can abut against the end of the partition 230 close to the clearance block 220 in the first direction.

[0031] In this embodiment, a protective cover 140 is disposed on the harness body 110 . The protective cover 140 can slide relative to the harness body 110 along a first direction and can rotate synchronously with the harness body 110 . In the initial state, the contact piece 120 is retracted into the protective cover 140 .

[0032] Specifically, the wiring harness body 110 is evenly distributed with a plurality of sliding keys around the first direction, and the protective cover 140 is provided with a plurality of sliding grooves, which are arranged along the first direction. The sliding keys and the sliding grooves are arranged one by one, and each sliding key is slidably installed in the sliding groove corresponding to it, so that the protective cover 140 can slide along the first direction relative to the wiring harness body 110, and can rotate synchronously with the wiring harness body 110.

[0033] The contact piece 120 can be retracted into the protective cover 140 when not in use. The protective cover 140 protects the contact piece 120 to prevent the contact piece 120 from being damaged by accidental contact.

[0034] In this embodiment, a plurality of contact pieces 120 are provided, and the plurality of contact pieces 120 are evenly distributed around the first direction on the harness body 110. The contact piece 120 is arc-shaped, and the two ends of the contact piece 120 along the first direction are respectively called a crimping end and a mounting end, the mounting end is fixedly connected to the harness body 110, the crimping end is located on the side of the mounting end away from the harness body 110 in the first direction, and the crimping end is located on the side of the mounting end away from the central axis of the harness body 110 in the first direction in the second direction, and the second direction is the radial direction of the harness body 110, so that the plurality of contact pieces 120 are divergent in a natural state.

[0035] In this embodiment, a plurality of the stoppers 220 are provided, and a plurality of stoppers 240 are evenly distributed around the first direction in the housing 210. The plurality of stoppers 240 and the plurality of stoppers 220 are sequentially arranged around the first direction in the housing 210, and the stoppers 240 and the stoppers 220 are alternately distributed around the first direction. An insertion space is defined between the plurality of stoppers 240 and the plurality of stoppers 220, and the insertion space is connected to the crimping cavity, so that the contact piece 120 can pass through the insertion space and extend into the crimping cavity.

[0036] The plurality of partitions 230 are arranged in one-to-one correspondence with the plurality of clearance blocks 220, and the projection of the partitions 230 and the corresponding clearance blocks 220 in the first direction overlap. The protective cover 140 has a plurality of push blocks 141, and the plurality of push blocks 141 are evenly distributed around the first direction on the protective cover 140. The plurality of push blocks 141 are arranged in one-to-one correspondence with the plurality of limit plates 130, and the limit plates 130 and the corresponding push blocks 141 are connected through the first elastic member 150, and the first elastic member 150 is arranged along the first direction, and the first elastic member 150 is a spring. The plurality of push blocks 141 are arranged in one-to-one correspondence with the plurality of clearance spaces, and each push block 141 can enter the housing 210 from the corresponding clearance space.

[0037] Furthermore, the end surface of one end of the clearance block 220 that contacts the contact piece 120 is an arc surface, so that the contact piece 120 can contact the clearance block 220 more closely.

[0038] In this embodiment, a stopper 240, a clearance block 220 and a push block 141 are arranged to cooperate with each other. When in use, the push block 141 extends into the shell 210 from the clearance space corresponding to it, and the push block 141 will enter the shell 210 synchronously with the limit plate 130 connected to it. As the wiring harness body 110 moves, one end of the push block 141 facing the stopper 240 will abut against the stopper 240, compressing the first elastic member 150, and the contact piece 120 will gradually extend out of the protective cover 140 in a divergent shape.

[0039] In this embodiment, the stopper 240 is fixed to the housing 210 , and the stopper 220 is connected to the housing 210 via a second elastic member 250 . The second elastic member 250 is disposed along the first direction and is a spring.

[0040] Specifically, a plurality of clearance grooves 260 are provided in the shell 210 , and the plurality of clearance grooves 260 are arranged in one-to-one correspondence with the plurality of clearance blocks 220 , and each clearance block 220 is slidably installed in the corresponding clearance groove 260 through the second elastic member 250 .

[0041] When one end of the limit plate 130 away from the clearance block 220 in the first direction is coplanar with the end of the partition 230 close to the clearance block 220 in the first direction, the wiring harness body 110 is rotated. The rotation of the wiring harness body 110 will drive the push block 141, the limit plate 130 and the contact piece 120 connected thereto to rotate synchronously, so that the limit plate 130 rotates to the side of the partition 230 corresponding to it, and abuts against the partition 230 corresponding to it.

[0042] Then the operator releases the push block 141, and the push block 141 moves toward the side close to the clearance block 220 under the action of the first elastic member 150, and the second elastic member 250 compresses the contact piece 120, thereby increasing the crimping strength between the clearance block 220 and the contact piece 120. It should be noted that the first elastic member 150 is reset so that the compression distance of the second elastic member 250 is shorter, and the first elastic member 150 is still in a compressed state.

[0043] In this embodiment, four of each of the limiting plate 130 , the pushing block 141 , the contact sheet 120 , the partition plate 230 , the stop block 240 and the clearance block 220 are provided.

[0044] In combination with the above embodiments, the specific working process is as follows:

[0045] When in use, the operator holds the wiring harness body 110 on one side of the male connector 100 and moves it closer to the female connector 200. Since the contact piece 120 is retracted into the protective cover 140 in the initial state, the contact piece 120 can be retracted into the protective cover 140 when not in use. The contact piece 120 is protected by the protective cover 140 to prevent accidental contact and damage to the contact piece 120.

[0046] Then, the push block 141 is extended into the shell 210 from the corresponding clearance space, and the push block 141 will synchronously move the limit plate 130 connected to it and enter the shell 210. As the wiring harness body 110 moves, one end of the push block 141 facing the stop block 240 will abut against the stop block 240, compressing the first elastic member 150, and the contact piece 120 will gradually extend out of the protective cover 140 in a divergent shape.

[0047] When the end of the limit plate 130 away from the clearance block 220 in the first direction is coplanar with the end of the partition 230 close to the clearance block 220 in the first direction, the wire harness body 110 is rotated, and the rotation of the wire harness body 110 will drive the push block 141, the limit plate 130 and the contact piece 120 connected thereto to rotate synchronously, so that the limit plate 130 rotates to the side of the partition 230 corresponding to it and abuts against the partition 230 corresponding to it. Then the operator lets go, and the push block 141 will move to the side close to the clearance block 220 under the action of the first elastic member 150, and the contact piece 120 will be compressed by the second elastic member 250, thereby increasing the crimping strength between the clearance block 220 and the contact piece 120.

[0048] When it is necessary to unlock the male connector 100 and the female connector 200, the operator only needs to rotate the wiring harness body 110. The rotation of the wiring harness body 110 will drive the push block 141, the limit plate 130 and the contact piece 120 connected thereto to rotate synchronously, so that the push block 141 rotates back to correspond to the corresponding clearance space set therewith. Then the operator lets go, the first elastic member 150 resets, and the limit plate 130 and the push block 141 pop open, completing the unlocking of the male connector 100 and the female connector 200.

[0049] 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.
