[0029] Refer to the following Figures 1-5Describe the wiring crimping device 100 according to an embodiment of the present utility model. A conductive crimping member 12 is disposed in the installation groove 11 of the first housing 1, and a crimping space for placing two wirings is formed between the conductive crimping member 12 and the second housing 2. Place the two wirings in the crimping space, press the second housing 2 to make the second housing 2 move relative to the first housing 1 and lock after being pressed. After being pressed, the two wirings are connected to the conductive crimping member 12 to form an electrical connection, which is equivalent to forming an electrical connection between the two wirings. The entire crimping process is convenient and reliable, and the wiring quality is good.

[0030] As Figures 1-5 shown, the wiring crimping device 100 according to an embodiment of the present utility model includes: a first housing 1, a conductive crimping member 12, and a second housing 2.

[0031] Among them, the first housing 1 is provided with an installation groove 11; the outer periphery of the conductive crimping member 12 is matched with the inner wall of the installation groove 11. The conductive crimping member 12 and at least one side of the installation groove 11 in the first direction are provided with wiring inlets, and the conductive crimping member 12 is further provided with a first open groove 121 that opens in the second direction; the second housing 2 is provided with a pressing portion 21. The second housing 2 is buckled with the first housing 1 in the second direction, and the first open groove 121 and the pressing portion 21 are opposite to form a crimping space for placing two wirings. The second housing 2 is movable relative to the first housing 1 so that the pressing portion 21 presses the conductive crimping member 12 and presses the conductive crimping member 12 and the two wirings. The first housing 1 and the second housing 2 are locked after being pressed.

[0032] In practice, first, the conductive crimping member 12 is disposed in the installation groove 11 to maintain the stability of the conductive crimping member 12. The second housing 2 is provided with a pressing portion 21, and the pressing portion 21 is opposite to the conductive crimping member 12 so that a crimping space is formed between the pressing portion 21 and the conductive crimping member 12. That is to say, in the initial state, the shape of the conductive crimping member 12 is the initial state, and the second housing 2 can be pressed and moved relative to the first housing 1, so that the crimping space formed between the conductive crimping member 12 and the pressing portion 21 gradually decreases. The conductive crimping member 12 is pressed and deformed in the gradually decreasing crimping space and connected to the wiring, thereby forming an electrical connection between the two wirings.

[0033] Specifically, the second direction is the direction in which the second housing 2 is fastened to the first housing 1, and the first direction intersects the second direction. When the electrical connection member 12 has a wiring inlet on one side in the first direction, at this time, two wirings are inserted into the crimping space along one side in the first direction. At this time, that is, the two wirings are located in the first open slot 121 of the electrical connection member 12, and the second housing 2 moves in the direction close to the first housing 1. When the pressing portion 21 crimps the electrical connection member 12, the electrical connection member 12 is gradually deformed and contacts both wirings, so that the electrical connection member 12 connects the two wirings. The electrical connection member 12 can be made of copper material, which has good electrical conductivity, enabling the two wirings to be connected and conduct electricity at the same time. At the same time, the copper material has good plasticity and ductility, and can be easily shaped into various shapes without breaking, making it more convenient to deform during crimping and connect to the two wirings. The connection here is at least an electrical connection in contact.

[0034] Of course, when the electrical connection member 12 has wiring inlets on both sides in the first direction, at this time, the two wirings are relatively inserted into the open slot of the electrical connection member 12 along both sides of the electrical connection member 12 in the first direction. When the second housing 2 approaches the first housing 1 and presses the electrical connection member 12, the electrical connection member 12 can be deformed and connected to the two wirings, thereby realizing reliable connection of the two wirings.

[0035] In addition, when the first housing 1 and the second housing 2 of the embodiment of the present invention press the electrical connection member 12 to a certain extent, the second housing 2 and the first housing 1 are locked. At this time, the second housing 2 cannot continue to move in the direction close to the first housing 1, and at this time, the electrical connection member 12 has been deformed and connected to the two wirings, and the first housing 1 and the second housing 2 can protect the connection positions of the two wirings.

[0036] Thus, the wiring crimping device 100 of the embodiment of the present invention crimps the two wirings through the first housing 1 and the second housing 2, so that the pressing portion 21 crimps the electrical connection member 12 and the wiring into one body, which is convenient and reliable, and the wiring quality is good.

[0037] In some embodiments, the second housing 2 includes a second open slot, and the inner wall of the second open slot forms a pressing portion 21 and is partially pressed against the outer wall of the electrical connection member 12, so that when the second housing 2 moves towards the first housing 1, the electrical connection member 12 is pressed and deformed, and both ends of the electrical connection member 12 approach and are pressed against the wiring.

[0038] In practice, the second open slot and the first open slot 121 of the electrical connection member 12 form a crimping space relatively, and during the process of the second housing 2 approaching the first housing 1, the crimping space gradually becomes smaller, so that the groove wall of the second open slot presses the electrical connection member 12, and the electrical connection member 12 is deformed, thereby facilitating the contact between the electrical connection member 12 and the two wirings and realizing electrical connection.

[0039] Refer to Figure 2 as shown Figure 2 is a schematic diagram before the second housing 2 is crimped. Figure 5 is a schematic diagram after the second housing 2 is crimped. In the initial state, the conductive crimping member 12 remains unchanged. The inner wall of the second open slot of the second housing 2 contacts a partial position of the conductive crimping member 12, especially at least in the top position. As the second housing 2 gradually approaches and is crimped relative to the first housing 1, the second housing 2 first crimps and deforms the top of the conductive crimping member 12. The first open slot 121 formed by the conductive crimping member 12 has an open mouth. During the deformation of the conductive crimping member 12, the open mouth of the first open slot 121 of the crimping member 12 gradually closes. At this time, the conductive crimping member 12 forms a closed structure. The inner wall of this closed structure contacts between the two wires and surrounds the outer periphery of the two wires, which is equivalent to connecting the two wires through the deformed conductive crimping member 12.

[0040] In some embodiments, the second open slot includes a slot bottom surface 211 and slot side walls 212 connected to both sides of the slot bottom surface 211. The slot bottom surface 211 presses against the outer walls of both ends of the conductive crimping member 12, and the two slot side walls 212 press against and limit the outside of the conductive crimping member 12.

[0041] Among them, in the initial state of the conductive crimping member 12, at least part of the two slot side walls 212 of the second open slot contact both sides of the open mouth of the conductive crimping member 12 to limit the conductive crimping member 12 and control the conductive crimping member 12 to produce controllable deformation within a suitable range.

[0042] At the same time, the top of the conductive crimping member 12 contacts the slot bottom surface 211 of the second open slot. That is to say, the second open slot can limit the conductive crimping member 12 while crimping the conductive crimping member 12. As the second housing 2 approaches the first housing 1, the slot bottom surface 211 of the second open slot presses against the top of the conductive crimping member 12. Combining the pressing of the slot side walls 212 against both sides of the conductive crimping member 12 and the pressing of the installation slot 11 against the bottom of the conductive crimping member 12, the conductive crimping member 12 is subjected to pressing forces from multiple directions, so that the conductive crimping member 12 can generate a deformation trend in which the two ends of the conductive crimping member 12 approach each other under the action of multiple side forces. That is, the open mouth of the second open slot of the conductive crimping member 12 gradually closes, so that the conductive crimping member 12 contacts the two wires and connects the two wires.

[0043] In some embodiments, the outer periphery of the conductive crimping member 12 is configured as an arc surface and is arc-shapedly matched with the installation slot 11. Arc transition surfaces 2112 are provided at positions where the slot bottom surface 211 is close to the two slot side walls 212, and the arc transition surfaces 2112 press against the outer walls of both ends of the arc surface.

[0044] In practice, the arc surface of the voltage-conducting connector 12 can first conform to the shape of the wiring, and can also effectively disperse and withstand pressure, preventing stress concentration, making the stress on the voltage-conducting connector 12 uniform, so as to avoid the problem that the voltage-conducting connector 12 has a large offset during deformation and is not easy to contact the wiring or has poor contact.

[0045] Furthermore, arc transition surfaces 2112 are provided at positions on the bottom surface 211 of the groove close to the two groove side walls 212. The arc transition surfaces 2112 are in arc-shaped pressing fit with the outer walls at both ends of the voltage-conducting connector 12. As the second housing 2 is gradually pressed towards the first housing 1, the arc transition surfaces 2112 can also evenly and gradually press the ends of the voltage-conducting connector 12, so that the two ends of the voltage-conducting connector 12 gradually approach each other, and the voltage-conducting connector 12 and the groove side wall 212 of the second open groove gradually change from a contact state to a non-contact state, as shown in Figure 5 shown, so that the voltage-conducting connector 12 deforms step by step and with uniform stress.

[0046] Specifically, the contact areas between the two ends of the voltage-conducting connector 12 and the two arc transition surfaces 2112 are the same, and the two arc transition surfaces 2112 are symmetrically distributed on both sides of the open side of the first open groove 121, further making the two ends of the voltage-conducting connector 12 deform towards each other with uniform stress, so as to maintain an effective connection between the voltage-conducting connector 12 and the two wirings.

[0047] In some embodiments, a pressing protrusion 2111 protruding towards the first housing 1 is provided in the middle of the bottom surface 211 of the groove. When the second housing 2 is pressed close to the first housing 1, both ends of the voltage-conducting connector 12 gradually approach the pressing protrusion 2111, and when the pressing is in place, both ends of the voltage-conducting connector 12 are attached to the side of the pressing protrusion 2111 close to the first housing 1.

[0048] As shown in Figure 2 shown, when the bottom surface 211 of the groove presses the voltage-conducting connector 12, both ends of the voltage-conducting connector 12 gradually approach the pressing protrusion 2111, that is, the pressing protrusion 2111 plays a guiding role at this time, so that after the two ends of the voltage-conducting connector 12 approach the pressing protrusion 2111, they can continue to move towards the lower part of the pressing protrusion 2111, that is, Figure 5 in this state. The setting of the pressing protrusion 2111 can cause the first open groove 121 to deform to form two sub-cavities after the voltage-conducting connector 12 is pressed. The two sub-cavities are respectively used to enclose a wiring, that is, the deformed first installation groove 11 surrounds the outsides of the two wirings and contacts the wirings, so that the voltage-conducting connector 12 contacts the wirings to form an electrical connection.

[0049] In practice, when the wire diameters of the two wirings are the same, the pressing protrusion 2111 is provided at the middle position of the groove bottom surface 211. Then, when the voltage-conducting connector 12 deforms and approaches the pressing protrusion 2111 in the middle, the end of the voltage-conducting connector 12 can be guided to the lower side of the pressing protrusion 2111, and the two ends of the voltage-conducting connector 12 contact on the lower side of the voltage-conducting connector 12, that is, the two ends of the voltage-conducting connector 12 contact at the middle position of the second open groove. The sizes of the two sub-cavities finally formed by the voltage-conducting connector 12 are basically the same, so as to meet the requirements of arranging wirings with the same wire diameter in the two sub-cavities, and both wirings are in contact with and electrically connected to the voltage-conducting connector 12.

[0050] Furthermore, the outer periphery of the pressing protrusion 2111 is an arc-shaped structure. When the pressing protrusion 2111 contacts the outer side surface of the voltage-conducting connector 12, it can have a better guiding effect on the voltage-conducting connector 12, and prevent the pressing protrusion 2111 from damaging the voltage-conducting connector 12 during the process of contacting and pressing the voltage-conducting connector 12. And when the second housing 2 is pressed towards the first housing 1, the arc-shaped pressing protrusion 2111 can gradually press against the voltage-conducting connector 12, so that the deformation range of the voltage-conducting connector 12 is controllable, and better connection of the voltage-conducting connector 12 to the two wirings is realized.

[0051] In some embodiments, guiding parts 16 are further provided on both sides of the installation groove 11 along the first direction, and the top surface height of the guiding parts 16 is higher than the height of the groove bottom surface 211 of the installation groove 11.

[0052] Refer to Figure 3 As shown, the arrangement of the guiding parts 16 facilitates the wiring to enter the first open groove 121 of the voltage-conducting connector 12. At the same time, after the voltage-conducting connector 12 is installed in the installation groove 11, both sides of the voltage-conducting connector 12 in the axial direction contact the guiding parts 16. That is, the guiding parts 16 not only have the function of guiding the wiring, but also can axially limit the voltage-conducting connector 12, so that when the voltage-conducting connector 12 is pressed, its axial position always remains unchanged, and it is only pressed in the radial direction, making the deformation of the pressing controllable and improving the pressing efficiency.

[0053] In some embodiments, one of the first housing 1 and the second housing 2 is provided with a plug-in groove 13 and the other is provided with a guiding protrusion 22, and the plug-in groove 13 and the guiding protrusion 22 extend along the second direction. When the second housing 2 and the first housing 1 are buckled, the guiding protrusion 22 and the plug-in groove 13 cooperate.

[0054] That is to say, when the second housing 2 approaches the first housing 1 and presses the voltage-conducting connector 12, the position of pressing the voltage-conducting connector 12 remains stable, preventing the position change between the first housing 1 and the second housing 2 from affecting the pressing effect; Refer to Figure 5As shown, the second housing 2 is provided with a guiding protrusion 22, and the first housing 1 is provided with a socket groove 13. When the second housing 2 approaches the first housing 1, the guiding protrusion 22 extends into the socket groove 13, enabling quick positioning and pressing.

[0055] Specifically, a plurality of guiding protrusions 22 are provided, and a plurality of socket grooves 13 are provided. The cooperation of the plurality of guiding protrusions 22 and the plurality of socket grooves 13 improves the force uniformity and pressing stability when the second housing 2 approaches the first housing 1 for pressing. Of course, the first housing 1 can also be provided with guiding protrusions 22, and the second housing 2 can be provided with socket grooves 13, which can also achieve the positioning function between the second housing 2 and the first housing 1.

[0056] In addition, a plurality of socket grooves 13 and a plurality of guiding protrusions 22 can be provided on the first housing 1, and a plurality of socket grooves 13 and a plurality of guiding protrusions 22 can also be provided on the second housing 2. While the plurality of guiding protrusions 22 on the first housing 1 cooperate with the plurality of socket grooves 13 on the second housing 2, the plurality of socket grooves 13 on the first housing 1 also cooperate with the plurality of guiding protrusions 22 on the second housing 2, so that the first housing 1 and the second housing 2 can be evenly stressed and the cooperation is more reliable.

[0057] In some embodiments, one of the first housing 1 and the second housing 2 is provided with a first locking position and a second locking position, and the other is provided with a locking portion. When the first housing 1 and the second housing 2 are buckled and the pressing portion 21 contacts the voltage-conducting connector 12, the locking portion cooperates and locks at the first locking position, and when the pressing portion 21 presses the voltage-conducting connector 12 to deform, the locking portion cooperates and locks at the second locking position.

[0058] In practice, for example, the first housing 1 is provided with a first locking position and a second locking position, the second housing 2 is provided with a locking portion, and the first locking position is the position where the locking portion is located when the second housing 2 and the first housing 1 are not pressed in place, and the second locking position is the position where the locking portion is located when the second housing 2 and the first housing 1 are pressed in place. By setting the first locking position and the second locking position, it is convenient for the connection between the second housing 2 and the first housing 1. At the same time, after the voltage-conducting connector 12 is pressed in place, the second housing 2 and the first housing 1 remain in a locked state and protect the connection of the two wires.

[0059] Of course, the first locking position and the second locking position can also be provided on the second housing 2, and the locking portion can be provided on the first housing 1. As the second housing 2 and the first housing 1 approach each other, the locking portion can change between the first locking position and the second locking position, and the locking effect can also be achieved when the second housing 2 and the first housing 1 approach each other and are pressed, which can be set according to the actual situation.

[0060] In addition, it should be noted that when the second housing 2 and the first housing 1 need to be disassembled under some special circumstances, an operating tool can be used to pry open the second housing 2. That is, in the normal use state, the second housing 2 and the first housing 1 are always locked and connected. When starting to crimp the two wires, the time for connecting the second housing 2 and the first housing 1 is saved. When the voltage conducting connector 12 and the two wires are crimped in place, they can also be kept locked all the time, protecting the connection between the two wires and the voltage conducting connector 12, preventing the connection from being exposed to the outside for a long time and causing potential safety hazards, and also preventing the connection from failing due to the influence of the environment when being exposed to the outside for a long time.

[0061] In some embodiments, the first locking position is provided with a first inclined groove 14, and the second locking position is provided with a second inclined groove 15. The first inclined groove 14 and the second inclined groove 15 are arranged at intervals along the second direction on the outer side of the first housing 1. The locking part is arranged on the second housing 2, and the locking part is configured as a locking hook 23 bent inward. The locking hook 23 is selectively clamped in the first inclined groove 14 or the second inclined groove 15.

[0062] In practice, that is, the second housing 2 and the first housing 1 are locked and cooperated through the locking hook 23 and the inclined groove. As Figure 5 shown, the first inclined groove 14 includes a first plane 141 and a first inclined surface 142. The first plane 141 is parallel to Figure 5 the horizontal direction, and the first inclined surface 142 is connected to one end of the first plane 141 and slopes downward. Similarly, the second inclined groove 15 includes a second plane 151 and a second inclined surface 152. The second plane 151 is parallel to Figure 5 the horizontal direction, and the second inclined surface 152 is connected to one end of the second plane 151 and slopes downward. The structure of the locking hook 23 cooperates with the structures of the first inclined groove 14 and the second inclined groove 15. When the locking hook 23 is located in the first inclined groove 14, at this time, the second housing 2 and the first housing 1 are not yet pressed tightly. The locking hook 23 includes a third plane 231 and a third inclined surface 232. At this time, the third plane 231 of the locking hook 23 contacts the first plane 141 of the first inclined groove 14, and the third inclined surface 232 contacts the first inclined surface 142 of the first inclined groove 14. As the second housing 2 continues to be pressed tightly towards the first housing 1, at this time, the third inclined surface 232 of the locking hook 23 gradually disengages from the first inclined surface 142 of the first inclined groove 14. After the pressing part 21 of the second housing 2 presses the voltage conducting connector 12 tightly, the third inclined surface 232 of the locking hook 23 contacts the second inclined surface 152 of the second inclined groove 15, and the third plane 231 contacts the second plane 151 of the second inclined groove 15 to lock.

[0063] Thus, by setting the first inclined groove 14, the second inclined groove 15 and the locking hook 23 to cooperate, it is convenient to lock the first housing 1 and the second housing 2 when the second housing 2 approaches the first housing 1, and the locking is reliable.

[0064] An embodiment of the present utility model also discloses a vehicle, which includes the above-mentioned wiring crimping device 100. A conductive crimping member 12 is arranged in the installation groove 11 of the first housing 1, and a crimping space for placing two wirings is formed between the conductive crimping member 12 and the second housing 2. The two wirings are placed in the crimping space, and the second housing 2 is tightened, so that the second housing 2 moves relative to the first housing 1 and is locked after being tightened. After being tightened, the two wirings are connected to the conductive crimping member 12 to form an electrical connection, which is equivalent to forming an electrical connection between the two wirings. The entire crimping process is convenient and reliable, the wiring quality is good, ensuring the reliable and fast wiring of the electrical equipment of the vehicle, and improving the wiring efficiency of the electrical equipment of the vehicle.
