Description

Technical Field

[0001] The present invention relates to the technical field of vehicle wire harnesses, and more particularly, to a wire harness connector assembly tooling and system. Background Art

[0002] With the rapid development of automotive electrification, intelligence, and new energy technologies, the complexity of automotive electrical systems has increased significantly, presenting multi-dimensional challenges to the performance requirements of wire harness connectors. As a key node in the electrical network, wire harness connectors need to achieve high-reliability signal transmission, power distribution, and environmental adaptability within a limited space. Their technological evolution is directly related to the safety, functional stability, and lightweight level of the entire vehicle. During the production and assembly process of automotive wire harness connectors, after passing the wire through the end cap, it is necessary to crimp the end cap onto the connector housing to achieve a firm connection between the housing and the wire. Traditional manual crimping tooling usually relies on manual force application to complete the crimping operation of the end cap and the housing.

[0003] However, manual crimping depends on manual force control, with low accuracy, and it is easy to cause the end cap and the housing to be incompletely crimped, resulting in a low pass rate during product inspection. Summary of the Invention

[0004] To solve the problem of incomplete crimping between the housing and the end cap of the wire harness connector, the present invention provides a wire harness connector assembly tooling and system.

[0006] In some embodiments, the reset power member includes an elastic member; one end of the elastic member is detachably connected to the sliding seat; the other end of the elastic member is detachably connected to the swing block; the tendency of the swing block to swing under the abutting force of the rack is the first swing direction; the tendency of the swing block to swing under the elastic force of the elastic member is the second swing direction; and the first swing direction is opposite to the second swing direction.

[0007] In some embodiments, the elastic member includes a tension spring; in the natural state where the swing block is separated from the rack, the tension spring is located on the side of the rotating shaft away from the base; the axis of the rotating shaft intersects perpendicularly with the axis of the tension spring.

[0008] In some embodiments, the elastic member includes compression springs; there are two compression springs; and the swing block is located between the two compression springs.

[0009] In some embodiments, the reset power member is a gravity driving member, which is integrally formed with the swing block; there is a spacing between the gravity driving member and the rotating shaft; in the natural state where the swing block is separated from the rack, the center of gravity of the swing block is located on the side of the rotating shaft facing the base.

[0010] In some embodiments, the spacing between the end of the swing block facing the base and the rotating shaft is the first spacing; the spacing between the rotating shaft and the base is the second spacing; and the ratio of the second spacing to the first spacing is between 60% and 80%.

[0011] In some embodiments, in the state where the swing block abuts against the rack, the edge of the end of the swing block close to the rack abuts against the root of the tooth of the rack.

[0012] In some embodiments, the tooth height of the rack gradually increases in the direction close to the limiting seat; and the tooth thickness of the rack gradually increases in the direction close to the limiting seat.

[0013] In some embodiments, the driving part includes a grip rod, a connecting rod, a transmission member, a push rod, a first hinge shaft, a second hinge shaft and a third hinge shaft; one end of the connecting rod is rotatably connected to one end of the grip rod through the first hinge shaft; the other end of the connecting rod is rotatably connected to the base through the second hinge shaft; one end of the transmission member is rotatably connected to the first hinge shaft, and the other end is rotatably connected to one end of the push rod through the third hinge shaft; and the end of the push rod away from the third hinge shaft is detachably connected to the sliding seat.

[0015] In order to solve the problem that the housing and the tail cover of the wiring harness connector cannot be crimped into place, the present invention has the following advantages: When the sliding seat moves, the swing block hits the rack at one end of the base, and the swing block swings, so that the swing block hits the multiple teeth on the rack in turn, so that the sliding seat can achieve resistance to unidirectional movement by utilizing the cooperation of the rack, the swing block and the reset power member. Therefore, when the sliding seat moves toward the limiting seat, the sliding seat can move away from the limiting seat only after the swing block is separated from the rack, thereby avoiding the erroneous operation of manual return due to failure to crimp in place as much as possible, and improving the qualified rate of crimping.

[0020] In the existing process of manually crimping the connector 80 to the wire 82, due to the short crimping distance and fast crimping speed of the connector 80, manual operation is prone to incomplete crimping due to force application errors. To improve the qualification rate of the assembly of the connector 80, this embodiment discloses an assembly tooling for the wire harness connector 80. In this embodiment, as Figure 1As shown, the harness connector 80 assembly tooling includes a base 10, a limiting seat 20, a sliding seat 40, a check part 60, and a driving part 70. The limiting seat 20 is detachably connected to the base 10, facilitating the replacement of different models of limiting seats 20 to meet the crimping requirements of different harness connectors 80; a plurality of wire grooves 30 are provided on the limiting seat 20 along a first direction, and the number of wire grooves 30 can be adjusted according to the number of wires in the harness; the sliding seat 40 is slidably connected to the base 10; the sliding direction of the sliding seat 40 is the first direction; the sliding seat 40 and the limiting seat 20 are arranged at intervals along the first direction; a limiting groove 50 is provided on the sliding seat 40; the limiting groove 50 is a profiling structure of the housing 81 of the connector 80, ensuring that there is no radial shaking after the connector 80 is placed in the limiting groove 50.

[0021] As Figure 1 , Figure 2 shown, the check part 60 may include a swing block 61, a rotating shaft 62, a rack 63, and a reset power member; the swing block 61 is rotatably connected to the sliding seat 40 through the rotating shaft 62, so that the swing block 61 can swing along the first direction; the rack 63 is detachably connected to the base 10, facilitating the subsequent replacement of the rack 63 or the adjustment of the position of the rack 63; the rack 63 is parallel to the first direction; as Figure 5 shown, in the natural state where the swing block 61 is disengaged from the rack 63, the distance between the rotating shaft 62 and the base 10 is greater than the height of the rack 63, and the distance between the swing block 61 and the base 10 is less than the height of the rack 63, so that one end of the swing block 61 away from the rotating shaft 62 can form an effective abutment with the rack 63; in the state where the swing block 61 abuts against the rack 63, the reset power member applies a reset force to the swing block 61; the direction in which the rack 63 drives the swing block 61 to swing is opposite to the direction in which the reset power member drives the swing block 61 to swing; the driving part 70 is detachably connected to the base 10; the driving part 70 is detachably connected to the sliding seat 40; the driving part 70 drives the sliding seat 40 to slide.

[0022] Through the above settings, when assembling the connector 80, the engagement and abutment between one end of the swing block 61 away from the rotating shaft 62 and the rack 63 can be used to prevent the sliding seat 40 from sliding away from the limiting seat 20, ensuring that the connector 80 is crimped in place and improving the crimping qualification rate of the connector 80.

[0023] In this embodiment, as Figure 4As shown, the reset power component includes an elastic component 64; one end of the elastic component 64 is detachably connected to the sliding seat 40; the other end of the elastic component 64 is detachably connected to the swing block 61; the tendency of the swing block 61 to swing under the abutting force of the rack 63 is the first swing direction; the tendency of the swing block 61 to swing under the elastic force of the elastic component 64 is the second swing direction; the first swing direction is opposite to the second swing direction. Through the above settings, when the swing block 61 abuts against the rack 63 and swings under the elastic force of the elastic component 64, the swing block 61 can have a reset tendency, thereby increasing the abutting force between the swing block 61 and the rack 63 and ensuring the anti-backflow effect of the anti-backflow part 60.

[0024] In this embodiment, as Figure 4 shown, the elastic component 64 can be a tension spring; in the natural state where the swing block 61 is separated from the rack 63, the tension spring is located on the side of the rotating shaft 62 away from the base 10; the axis of the rotating shaft 62 intersects perpendicularly with the axis of the tension spring. The tension spring during installation is in a pre-stretched state to ensure that when the swing block 61 abuts against the rack 63 during the sliding of the sliding seat 40, it swings upward (the first swing direction), and the pulling force of the tension spring forces the swing block 61 to reset downward (the second swing direction).

[0025] In this embodiment, the elastic component 64 can be a compression spring; there are two compression springs, which can be symmetrically arranged on both sides of the rotating shaft 62; the swing block 61 is located between the two compression springs. In the initial state, the compression springs are in a compressed state, and the elastic force of the compression springs can push the swing block 61 to swing downward to keep abutting against the tooth surface of the rack 63.

[0026] In this embodiment, the reset power component is a gravity-driven component, and the gravity-driven component is integrally formed with the swing block 61; there is a distance between the gravity-driven component and the rotating shaft 62; in the natural state where the swing block 61 is separated from the rack 63, the center of gravity of the swing block 61 is located on the side of the rotating shaft 62 facing the base 10. In the natural state, the swing block 61 hangs down due to the lower center of gravity, so that when the swing block 61 abuts against the rack 63 and swings during the process of the swing block 61 swinging under the action of gravity, the swing block 61 can have a reset tendency.

[0027] In this embodiment, the distance between one end of the swing block 61 facing the base 10 and the rotating shaft 62 is the first distance; the distance between the rotating shaft 62 and the base 10 is the second distance; the ratio of the second distance to the first distance is between 60% and 80%. Through the above settings, as Figure 6As shown, when designing the clearance between the swinging block 61 and the tooth root of the rack 63, one end of the swinging block 61 needs to be inserted into the tooth groove of the rack 63 first, and then the distance between the rotating shaft 62 and the base 10 is adjusted, so as to adjust the clearance between the swinging block 61 and the bottom of the tooth groove of the rack 63. The smaller the clearance is, the faster the response to prevent the return during the return operation due to incomplete crimping, that is, the smaller the oscillation amplitude during the check valve operation. However, the smaller the clearance is, it is easy to cause that when the sliding seat 40 moves normally, the rotation range of the position on the swinging block 61 farthest from the rotating shaft 62 is relatively large and it is easy to interfere with the teeth of the rack 63, so that the swinging block 61 is blocked both when moving forward and backward and gets stuck in place. Therefore, the design of the clearance between the swinging block 61 and the bottom of the tooth groove of the rack 63 is relatively important. In some embodiments of the present invention, in the case of adopting a gravity driving member, the second distance is relatively long, so that when the end of the swinging block 61 facing the base 10 swings around the rotating shaft 62, even if the shape of the end of the swinging block 61 is polygonal, such as rectangular, the arc paths of each position of the end of the swinging block 61 close to the base 10 are relatively close, so that it is easy to control the rotation range of each position of the swinging block 61. Thus, the clearance between the swinging block 61 and the bottom of the tooth groove of the rack 63 can be minimized as much as possible to increase the check valve response speed.

[0028] In this embodiment, as Figure 7 shown, in the state where the swinging block 61 abuts against the rack 63, the edge of the end of the swinging block 61 close to the rack 63 abuts against the tooth root of the rack 63. During the process that the swinging block 61 impacts multiple teeth on the rack 63 in sequence, since the number of impacts of the swinging block 61 is the sum of the number of impacts of all teeth, the swinging block 61 bears a relatively large number of impacts. In order to avoid serious wear of the swinging block 61 and reduce the impact damage of the teeth of the rack 63 on the swinging block 61, the solution of contacting the tooth root of the rack 63 with the edge of the swinging block 61 is adopted, so that the swinging block 61 bears an impact on a surface rather than on a tip, thereby effectively protecting the swinging block 61. At the same time, since the position where the edge of the end of the swinging block 61 close to the rack 63 abuts against the rack 63 is the tooth root (that is, the tooth surface of the rack 63), the thickness of the tooth root is thicker than that of the tooth top, so the strength is higher, and it can also ensure the service life of the rack 63 under impact. Thus, by taking into account the wear life of both the rack 63 and the swinging block 61, the service life of the entire check valve portion 60 can be extended.

[0029] In this embodiment, the tooth height of the rack 63 gradually increases in the direction close to the limiting seat 20. Since the probability of manual misoperation is greater when the sliding seat 40 is closer to the limiting seat 20, such a setting can make it easier for the driving part 70 when the swinging block 61 initially abuts against the rack 63. When the sliding seat 40 slides to the latter half of the pressing path, the check part 60 can provide a greater check force to ensure that the sliding seat 40 will not retract during crimping, improving the check effect; the tooth thickness of the rack 63 gradually increases in the direction close to the limiting seat 20, thereby enhancing the structural strength of the rack 63 and preventing the rack 63 from being damaged by fatigue. And through the above setting, the tooth pitch of the rack 63 will also change accordingly, and the impact volume between the swinging block 61 and the rack 63 will also change with the sliding stroke of the sliding seat 40, thereby reminding the operator whether the crimping is in place.

[0030] In this embodiment, as Figure 2 shown, the driving part 70 includes a grip rod 71, a connecting rod 72, a transmission part 73, a push rod 74, a first hinge shaft 75, a second hinge shaft 76 and a third hinge shaft 77; one end of the connecting rod 72 is rotatably connected to one end of the grip rod 71 through the first hinge shaft 75. The other end of the connecting rod 72 is rotatably connected to the base 10 through the second hinge shaft 76; one end of the transmission part 73 is rotatably connected to the first hinge shaft 75, and the other end is rotatably connected to one end of the push rod 74 through the third hinge shaft 77; the end of the push rod 74 away from the third hinge shaft 77 is detachably connected to the sliding seat 40. Through the above setting, when the grip rod 71 is lifted upward, the connecting rod 72 can rotate clockwise around the second hinge shaft 76, driving the transmission part 73 to push the push rod 74 to move to the right, driving the sliding seat 40 to slide in the first direction; if the grip rod 71 is accidentally released, the swinging block 61 will reset due to the pulling force of the elastic part 64 and its own gravity, and abut against the tooth root of the rack 63, thereby locking the current position of the sliding seat 40, enabling the operator to judge whether the connector 80 is crimped in place.

[0031] In this embodiment, this embodiment discloses a wiring harness connector 80 assembly system, as Figure 1 、 Figure 2 、 Figure 3As shown, the wiring harness connector 80 assembly system includes the wiring harness connector 80 assembly tooling of any one of the above embodiments; the wiring harness connector 80 assembly system further includes a connector 80 and a wire 82. The connector 80 includes a housing 81, a tail cover 83, and a sealing ring 84; the diameter of the tail cover 83 is greater than the width of the wire groove 30; in the state where the connector 80 is assembled, one end of the wire 82, the tail cover 83, and the sealing ring 84 are clamped in the housing 81; before the connector 80 is assembled, in the state where the positioning is completed on the wiring harness connector 80 assembly tooling, the housing 81 is clamped in the limiting groove 50 of the sliding seat 40 of the wiring harness connector 80 assembly tooling, the wire 82 is threaded through the wire groove 30, the tail cover 83 and the sealing ring 84 are sleeved on the end of the wire 82, and the tail cover 83 and the sealing ring 84 are located on the side of the limiting seat 20 facing the sliding seat 40, and the sealing ring 84 is located on the side of the tail cover 83 facing the housing 81.

[0032] The positioning and fixing of the housing 81 of the connector 80 are completed through the limiting groove 50 in the wiring harness connector 80 assembly tooling. The sliding seat 40 is driven by the driving part 70 to slide so as to press the wire 82, the tail cover 83, and the sealing ring 84 of the connector 80 into the housing 81. During the pressing process, the swing block 61 of the check part 60 cooperates with the rack 63 to ensure the pressing accuracy and prevent the sliding seat 40 from moving away from the limiting seat 20 before the pressing is completed.
