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 vehicle's safety, functional stability, and lightweight level. 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, which easily leads to incomplete crimping of the end cap and the housing, resulting in a low qualified rate during product inspection. Summary of the Invention

[0012] In some embodiments, the elastic component includes a tension spring; in the natural state where the swing block is disengaged 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 is vertically intersecting with the axis of the tension spring.

[0013] In some embodiments, the elastic component includes a compression spring; there are two compression springs; the swing block is located between the two compression springs.

[0014] In some embodiments, the reset power component is a gravity driving component, the gravity driving component is integrally formed with the swing block; there is a distance between the gravity driving component and the rotating shaft; in the natural state where the swing block is disengaged from the rack, the center of gravity of the swing block is located on the side of the rotating shaft facing the base.

[0015] In some embodiments, the distance between the end of the swing block facing the base and the rotating shaft is the first distance; the distance between the rotating shaft and the base is the second distance; the ratio of the second distance to the first distance is between 60% and 80%.

[0016] 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.

[0017] In some embodiments, the tooth height of the rack gradually increases in a direction approaching the limiting seat; and the tooth thickness of the rack gradually increases in a direction approaching the limiting seat.

[0024] In order to solve the problem that the housing and tail cover of the wiring harness connector are not crimped into place, the present invention has the following advantages:

[0025] When the sliding seat moves, the swing block, which is facing the base, strikes the rack. The swing block swings, causing it to sequentially strike multiple teeth on the rack. The rack, swing block, and reset element work together to create resistance to the sliding seat's unidirectional movement. Therefore, when the sliding seat moves toward the limiting seat, the swing block must disengage from the rack before the sliding seat can move away from the limiting seat. This minimizes manual retraction after the crimping is not in place, improving the crimping yield. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] 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 caused by force application errors. In order to improve the qualification rate of the assembly of the connector 80, this embodiment discloses an assembly tool for a wire harness connector 80. In this embodiment, as Figure 1As shown, the harness connector 80 assembly tooling includes a base 10, a restricting seat 20, a sliding seat 40, a check valve portion 60, and a driving portion 70. The restricting seat 20 is detachably connected to the base 10, facilitating the replacement of different models of restricting seats 20 to meet the crimping requirements of different harness connectors 80; a plurality of wire grooves 30 are provided on the restricting seat 20 along a first direction, and the number of wire grooves 30 can be adjusted according to the number of wires; 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 restricting 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 wobbling after the connector 80 is placed in the limiting groove 50.

[0037] As Figure 1 , Figure 2 shown, the check valve portion 60 may include a swing block 61, a rotating shaft 62, a rack 63, and a reset power component; the swing block 61 is rotatably connected to the sliding seat 40 through the rotating shaft 62, enabling the swing block 61 to swing along the first direction; the rack 63 is detachably connected to the base 10, facilitating the subsequent replacement of the rack 63 or 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 the 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 component 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 component drives the swing block 61 to swing; the driving portion 70 is detachably connected to the base 10; the driving portion 70 is detachably connected to the sliding seat 40; the driving portion 70 drives the sliding seat 40 to slide.

[0038] Through the above settings, when assembling the connector 80, the engagement and abutment between the 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 restricting seat 20, ensuring that the connector 80 is crimped in place and improving the crimping qualification rate of the connector 80.

[0039] 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 swings during the abutting process between the swing block 61 and the rack 63 by using 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 portion 60.

[0040] 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 is vertically intersecting with the axis of the tension spring. The tension spring during installation is in a pre-tensioned state to ensure that the swing block 61 swings upward (the first swing direction) when the swing block 61 abuts against the rack 63 during the sliding of the sliding seat 40, and the pulling force of the tension spring forces the swing block 61 to reset downward (the second swing direction).

[0041] 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.

[0042] 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 spacing 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 remains drooping due to the lower center of gravity, so that when the swing block 61 swings during the abutting process between the swing block 61 and the rack 63 under the action of gravity, the swing block 61 can have a reset tendency.

[0043] 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 gap between the swing block 61 and the tooth root of the rack 63, it is necessary to first insert one end of the swing block 61 into the tooth groove of the rack 63, and then adjust the distance between the rotating shaft 62 and the base 10, so as to adjust the gap between the swing block 61 and the bottom of the tooth groove of the rack 63. The smaller the gap is, the faster the response to prevent the return is when the crimping is not in place and the return operation is performed, that is, the smaller the oscillation amplitude during the check valve operation. However, the smaller the gap is, it is easier to cause interference between the tooth of the rack 63 and the position on the swing block 61 that is farthest from the rotating shaft 62 when the sliding seat 40 moves normally, resulting in the forward and backward movement of the swing block 61 being blocked and getting stuck in place. Therefore, the design of the gap between the swing block 61 and the bottom of the tooth groove of the rack 63 is relatively important. In some embodiments of the present invention, when a gravity driving member is adopted, the second distance is longer, so that when the swing block 61 swings around the rotating shaft 62 with the end towards the base 10, even if the shape of the end of the swing block 61 is polygonal, such as rectangular, the arc paths of the swing block 61 at various positions near the base 10 are relatively close, making it easy to control the rotation range of the swing block 61 at various positions. Thus, the gap between the swing 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.

[0044] In this embodiment, as Figure 7 shown, in the state where the swing block 61 abuts against the rack 63, the edge of the end of the swing block 61 close to the rack 63 abuts against the tooth root of the rack 63. During the process of the swing block 61 hitting multiple teeth on the rack 63 in sequence, since the number of impacts of the swing block 61 is the sum of the number of impacts of all teeth, the swing block 61 bears a relatively large number of impacts. In order to avoid serious wear of the swing block 61 and reduce the impact damage of the teeth of the rack 63 on the swing block 61, the solution of the tooth root of the rack 63 contacting the edge of the swing block 61 is adopted, so that the swing block 61 bears an impact on a surface rather than a tip, thereby effectively protecting the swing block 61. At the same time, since the position where the edge of the end of the swing block 61 close to the rack 63 abuts against the rack 63 is the tooth root (i.e., 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, which can also ensure the service life of the rack 63 under impact. By taking into account the wear life of both the rack 63 and the swing block 61, the service life of the entire check valve portion 60 can be extended.

[0045] In this embodiment, the tooth height of the rack 63 gradually increases as it approaches the limiting seat 20. Since the closer the sliding seat 40 approaches the limiting seat 20, the greater the probability of manual misoperation, this arrangement allows the driving unit 70 to save effort when the swing block 61 initially contacts the rack 63. When the sliding seat 40 slides to the second half of the press-fitting path, the check member 60 can provide a greater non-return force to ensure that the sliding seat 40 does not retreat during the press-fitting process, thereby improving the non-return effect. The tooth thickness of the rack 63 gradually increases as it approaches the limiting seat 20, thereby enhancing the structural strength of the rack 63 and preventing fatigue damage to the rack 63. Furthermore, through this arrangement, the tooth pitch of the rack 63 also changes accordingly, and the impact sound of the swing block 61 and the rack 63 also changes with the sliding travel of the sliding seat 40, thereby reminding the operator whether the press-fitting is in place.

[0046] In this embodiment, if Figure 2 As shown, the driving unit 70 includes a handle 71, a connecting rod 72, a transmission member 73, a push rod 74, a first hinge axis 75, a second hinge axis 76, and a third hinge axis 77. One end of the connecting rod 72 is rotatably connected to one end of the handle 71 via the first hinge axis 75. The other end of the connecting rod 72 is rotatably connected to the base 10 via the second hinge axis 76. One end of the transmission member 73 is rotatably connected to the first hinge axis 75, and the other end is rotatably connected to one end of the push rod 74 via the third hinge axis 77. The end of the push rod 74 away from the third hinge axis 77 is detachably connected to the sliding seat 40. Through the above arrangement, when the grip 71 is lifted upward, the connecting rod 72 can rotate clockwise around the second hinge shaft 76, driving the transmission member 73 to push the push rod 74 to move to the right, driving the sliding seat 40 to slide along the first direction; if the grip 71 is accidentally released, the swing block 61 is reset due to the tension of the elastic member 64 and its own gravity, abutting the root of the rack 63, thereby locking the current position of the sliding seat 40, so that the operator can determine whether the connector 80 is crimped into place.

[0047] In this embodiment, this embodiment discloses a wiring harness connector 80 assembly system, such 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 arranged in 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.

[0048] 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 swinging 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.

[0049] It should be understood that the "present embodiment" mentioned in the present invention refers to the current technical points. Multiple "present embodiments" can be the same embodiment or different embodiments.

[0050] Those of ordinary skill in the art can understand that the above embodiments are specific examples for implementing the present disclosure, and in practical applications, various changes can be made in form and details without departing from the scope of the present disclosure.
