Description

Technical Field

[0001] This invention relates to the field of wire harness connector foolproof technology, and more particularly to a modular wire harness foolproof insertion and removal guide device. Background Technology

[0002] Wire harness foolproof insertion and removal refers to ensuring, through structural design or auxiliary devices, that the operator can only complete the insertion in the single correct direction, sequence, or position during the wire harness connector mating process. This fundamentally avoids terminal damage, poor contact, electrical short circuits, or equipment failures caused by human errors such as misinsertion, reverse insertion, or misalignment.

[0003] In existing wire harness plug-in guide devices, when multiple sockets have the same plug cross-section but different internal foolproof positioning hole angles, a fixed, one-to-one foolproof guide relationship must be formed between each plug and socket. This requires manufacturing a dedicated guide device with a fixed angle for each plug, or relying on the operator's on-site memory or trial and error to determine the correspondence between the plug and socket. Once the plug is replaced and needs to be adapted to another socket, the entire guide device must be reconfigured or replaced, reducing the reusability flexibility of the guide device in modular multi-plug, multi-socket scenarios. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide a modular wire harness anti-foolproof plugging and unplugging guide device, which can achieve anti-foolproof plugging and unplugging without the need to equip each plug with a dedicated guide device with a fixed angle, thereby improving the reusability of the guide device in modular multi-plug and multi-socket scenarios.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A modular wire harness foolproof insertion and removal guide device includes:

[0007] The socket has a power connection socket and multiple positioning sockets, which are arranged in a circular array around the power connection socket and are equally spaced.

[0008] A ring-shaped mounting base is used to mount the gripping part of the foolproof wire harness plug; the ring-shaped mounting base is provided with multiple positioning grooves, which are distributed at intervals around the axis of the ring-shaped mounting base.

[0009] The positioning fitting includes a positioning block, which is rotatably fitted onto the annular mounting base. The positioning block is rotatably embedded in one of the positioning slots. The positioning fitting has multiple positioning inserts, which are arranged in a circumferential array around the axis of the annular mounting base and distributed at equal intervals. The multiple positioning inserts are used to be inserted into the multiple positioning holes one by one.

[0010] Furthermore, a first inclined portion is provided on one side of the positioning groove, the first inclined portion is located on the rotation path of the positioning fitting and is inclined from the outside of the positioning groove to the inside of the positioning groove; a second inclined portion is provided on one side of the positioning block, the second inclined portion is inclined in the same direction as the first inclined portion, so that when the positioning block rotates around the circumference of the annular mounting base, the positioning block can be inserted into or disengaged from one of the positioning grooves.

[0011] Furthermore, the positioning fitting also includes a rotary ring, a first reset elastic element, and a limiting telescopic rod; the rotary ring is rotatably fitted onto the circumferential surface of the annular mounting base; one end of the first reset elastic element is connected to the rotary ring, and the other end is connected to the positioning block, so that when the positioning block is embedded in one of the positioning slots, the positioning block has a tendency to move away from the rotary ring; the two ends of the limiting telescopic rod are respectively connected to the rotary ring and the positioning block.

[0012] Furthermore, the modular wire harness anti-foolproof insertion and removal guide device is also provided with a protective ring, the inner wall of which is provided with an internal thread; the circumferential surface of the annular mounting base is also provided with an external thread, the external thread being located at one end of the annular mounting base away from the positioning groove, the external thread being threadedly connected to the internal thread, so that when the protective ring moves toward the positioning groove, the protective ring can cover the positioning mating part.

[0013] Furthermore, the positioning block has a clamping portion that extends radially along the annular mounting base, so that when the protective ring moves toward the positioning groove, the protective ring can clamp the clamping portion.

[0014] Furthermore, the modular wire harness anti-foolproof insertion and removal guide device also includes a rotary lever; the rotary lever is hinged to the rotary ring via a damping shaft and is used for manual operation to drive the rotary ring to rotate.

[0015] Furthermore, the circumferential surface of the annular mounting base is provided with an annular limiting guide rail, the embedding depth of which extends along the circumferential axis of the annular mounting base and rotates in cooperation with the positioning block around the circumferential axis of the annular mounting base.

[0016] Furthermore, a modular wire harness anti-misplacement guide device also includes a bolt and a wedge-shaped clamping block; the annular mounting base is provided with a mounting hole, an internal threaded hole, and a guide groove; the mounting hole is used to install the anti-misplacement wire harness plug; the internal threaded hole extends along the circumferential axis of the annular mounting base and is used to thread-mate with the bolt; the guide groove extends radially bidirectionally along the annular mounting base until it communicates with the internal threaded hole and the mounting hole respectively, and slides with the wedge-shaped clamping block so that when the bolt enters the internal threaded hole, the bolt pushes the wedge-shaped clamping block to press the gripping part of the anti-misplacement wire harness plug.

[0017] Furthermore, the annular mounting base is also provided with a reset clearance groove and a second reset elastic member; the reset clearance groove extends radially along the annular mounting base and communicates with the guide groove; one end of the second reset elastic member is connected to the annular mounting base, and the other end is connected to the wedge-shaped clamping block, so that when the wedge-shaped clamping block clamps the gripping part of the foolproof wire harness plug, the wedge-shaped clamping block has a gripping part away from the foolproof wire harness plug.

[0018] Furthermore, the circumferential surface of the protective ring is provided with anti-slip texture, which is used to prevent the hand from slipping out of the foolproof wire harness plug when rotating and plugging / unplugging the foolproof wire harness plug.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. Based on the ring-shaped mounting base for mounting the gripping part of the foolproof wire harness plug, and the positioning fitting rotatably fitted onto the ring-shaped mounting base, the positioning fitting responsible for angle adjustment and the mounting base responsible for gripping force in the guide device work independently yet collaboratively. Operators only need to prepare a small number of universal guide devices, which can be quickly rotated and adjusted on-site according to the positioning hole orientation of the actual socket and then installed on the gripping part of different plugs. There is no need to pre-customize a guide structure with a fixed angle for each plug, thereby improving the reusability and on-site adaptation efficiency of the guide device in modular multi-plug and multi-socket scenarios.

[0021] 2. The ring-shaped mounting base has multiple positioning slots, and the positioning fitting has a positioning block. The positioning fitting is rotatably sleeved on the ring-shaped mounting base, and the positioning block is rotatably embedded in one of the positioning slots. This allows the same guide device to rotate the positioning fitting to engage the positioning block in different positioning slots, thereby changing the circumferential starting angle of the positioning insert. Thus, when dealing with multiple sockets with different positioning hole angles, there is no need to replace or redesign the guide device; simply rotating and adjusting is sufficient to match them one by one. This achieves compatibility of a single guide device with multiple angle specifications, improving the reusability and flexibility of the device.

[0022] 3. Based on the circumferential array of multiple positioning strips surrounding the axis of the annular mounting base and distributed at equal intervals, and the fact that multiple positioning strips are used to connect one-to-one with multiple positioning holes, the positioning strips and positioning holes always maintain the same array correspondence regardless of the rotation position of the positioning mating component. The foolproof guiding function will not fail due to angle adjustment. Therefore, the same guiding device can be reliably used in multiple different plug or socket scenarios, eliminating the need for a separate fixed-angle guiding device for each plug, thereby reducing the spare parts pressure of modular wiring harness systems and improving reuse flexibility.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] See Figures 1-5 The specific implementation methods of all embodiments of the present invention are as follows:

[0035] A modular wire harness anti-foolproof insertion and removal guide device includes a socket 1, an annular mounting base 4, and a positioning mating part 7.

[0036] The socket 1 has a power connection hole 2 and multiple positioning holes 3. The multiple positioning holes 3 are arranged in a circular array around the power connection hole 2 and are evenly spaced. Specifically, the positioning holes 3 are blind holes or through holes, and their opening edges may be provided with chamfers or guide cone surfaces to guide the positioning insert 71 to be smoothly inserted; the number of multiple positioning holes 3 is at least two to ensure unique circumferential anti-foolproof positioning in the circumferential direction.

[0037] The annular mounting base 4 is used to mount the gripping part 5 of the foolproof wire harness plug 21. The annular mounting base 4 is provided with multiple positioning grooves 6, which are distributed at intervals around the axis of the annular mounting base 4. Specifically, the mounting method of the annular mounting base 4 and the gripping part 5 of the foolproof wire harness plug 21 includes at least directly encapsulating the gripping part 5 onto the outer periphery of the annular mounting base 4 by injection molding, or clamping and fixing the separate gripping part 5 to the outer side wall of the annular mounting base 4 by screws. The positioning groove 6 is a rectangular groove or trapezoidal groove extending along the axial direction, and its bottom may be provided with a magnetic insert or elastic damping layer for adsorbing the positioned block 20.

[0038] The positioning fitting 7 is provided with a positioning block 20. The positioning fitting 7 is rotatably sleeved on the annular mounting base 4. The positioning block 20 is rotatably embedded in one of the positioning grooves 6. The positioning fitting 7 is provided with multiple positioning inserts 71. The multiple positioning inserts 71 are arranged in a circumferential array around the axis of the annular mounting base 4 and are distributed at equal intervals. The multiple positioning inserts 71 are used to be inserted into the multiple positioning holes 3 one by one. Specifically, the fitting method between the positioning fitting 7 and the annular mounting base 4 includes at least the following: the positioning fitting 7 has an annular ball groove on its inner wall that cooperates with the annular guide rail on the outer wall of the annular mounting base 4 to form a rolling rotary pair; or a sliding bearing bushing is provided between the two to form a sliding rotary pair. The fitting between the positioned block 20 and the positioning groove 6 includes at least the positioned block 20 using an elastic rubber block that is interference-fitted with the positioning groove 6 to achieve damping positioning; or the positioned block 20 is a telescopic pin structure with a built-in spring, which is pushed into the positioning groove 6 by the spring force to achieve elastic locking. The front end of the positioning insert 71 may be provided with a chamfered or hemispherical guide head, and the length of the positioning insert 71 is set such that it leaves a gap with the bottom of the positioning insertion hole 3 or abuts against the bottom of the hole when inserted.

[0039] The principle of the modular wire harness anti-foolproof insertion and removal guide device of the present invention is as follows:

[0040] First, based on a pre-known specific socket 1 that can form a correct electrical connection with the plug, the circumferential distribution of multiple positioning holes 3 on the socket 1 is determined. Then, the annular mounting base 4 of the device is installed on the gripping part 5 of the plug, and the positioning fitting 7 sleeved on the base is rotated to make the positioning block 20 embedded in the corresponding positioning groove 6, so that the circumferential angle of the multiple positioning strips 71 uniquely matches the position of the positioning hole 3 on the specific socket 1, thus completing the preset of the foolproof configuration. After that, even if the plug is pulled out during transportation, the subsequent operator does not need to know which socket 1 the plug originally corresponded to (especially applicable to multiple foolproof wire harness plugs 21 with the same shape, but need to be connected to different function power sockets 2). They only need to observe or directly insert it when inserting. Since the positioning strips 71 and positioning holes 3 cannot be fully inserted when the angles do not match, the operator can only achieve accurate alignment of the positioning strips 71 and positioning holes 3 on the only socket 1 that matches the plug and complete the insertion, thus ensuring the correctness of each insertion after multiple insertions, removals and transportations.

[0041] Clearly, based on the ring-shaped mounting base 4 for mounting the gripping part 5 of the foolproof wire harness plug 21, and the positioning fitting 7 rotatably fitted onto the ring-shaped mounting base 4, the positioning fitting 7 responsible for angle adjustment and the mounting base responsible for gripping force in the guide device work independently yet collaboratively. Operators only need to prepare a small number of universal guide devices, which can be quickly rotated and adjusted on-site according to the orientation of the positioning socket 3 of the actual socket 1, and then installed on the gripping part 5 of different plugs. There is no need to pre-customize a guide structure with a fixed angle for each plug, thereby improving the reusability and on-site adaptation efficiency of the guide device in modular multi-plug, multi-socket 1 scenarios.

[0042] The annular mounting base 4 has multiple positioning slots 6, and the positioning fitting 7 has a positioning block 20. The positioning fitting 7 is rotatably sleeved on the annular mounting base 4, and the positioning block 20 is rotatably embedded in one of the positioning slots 6. This allows the same guide device to rotate the positioning fitting 7 to engage the positioning block 20 in different positions of the positioning slots 6, thereby changing the circumferential starting angle of the positioning insert 71. In this way, when facing multiple sockets 1 with different positioning hole angles 3, there is no need to replace or redesign the guide device. Simply rotate and adjust to match them one by one. This achieves compatibility of a single guide device with multiple angle specifications and improves the reusability and flexibility of the device.

[0043] Based on the circumferential array of multiple positioning strips 71 surrounding the axis of the annular mounting base 4 and evenly spaced, and the fact that the multiple positioning strips 71 are used to connect one-to-one with multiple positioning holes 3, the positioning strips 71 and positioning holes 3 always maintain the same array correspondence regardless of the position of the positioning mating part 7. The foolproof guiding function will not fail due to angle adjustment. Therefore, the same guiding device can be reliably used in multiple different plugs or different sockets 1 scenarios, eliminating the need to equip each plug with a dedicated guiding device with a fixed angle, thereby reducing the spare parts pressure of the modular wiring harness system and improving reuse flexibility.

[0044] Preferably, one side of the positioning groove 6 is provided with a first inclined portion, which is located on the rotation path of the positioning fitting 7 and is inclined from the outside of the positioning groove 6 to the inside of the positioning groove 6; one side of the positioning block is provided with a second inclined portion, which is inclined in the same direction as the first inclined portion, so that when the positioning block rotates circumferentially along the annular mounting base 4, the positioning block can be inserted into or disengaged from one of the positioning grooves 6. Specifically, the first inclined portion is provided on the groove wall of the positioning groove 6 on the exit side and is inclined from the outside of the positioning groove 6 to the inside of the positioning groove 6; the second inclined portion is correspondingly provided on the side wall of the positioning block 20 on the exit side, and the second inclined portion is inclined in the same direction as the first inclined portion; when the positioning fitting 7 rotates in the opposite direction circumferentially, the second inclined portion and the first inclined portion abut against each other and slide relative to each other along the inclined surface, so that the positioning block 20 gradually disengages from the positioning groove 6 under the lifting action of the inclined surface, thereby achieving a smooth separation of the positioning block 20 from the positioning groove 6.

[0045] Preferably, the positioning and mating component 7 further includes a rotating ring 72, a first reset elastic element 73, and a limiting telescopic rod 74; the rotating ring 72 is rotatably sleeved on the circumferential surface of the annular mounting base 4; one end of the first reset elastic element 73 is connected to the rotating ring 72, and the other end is connected to the positioning block, so that when the positioning block is embedded in one of the positioning slots 6, the positioning block has a tendency to move away from the rotating ring 72; the two ends of the limiting telescopic rod 74 are respectively connected to the rotating ring 72 and the positioning block. Specifically, the mating structure of the first reset elastic element 73 and the limiting telescopic rod 74 includes at least the following two implementation methods: First, the first reset elastic element 73 is a compression spring sleeved on the outer periphery of the limiting telescopic rod 74, with one end of the compression spring abutting against the rotating ring 72 and the other end abutting against the positioning block, used to store energy when the positioning block is disengaged from the positioning slot 6 and push the positioning block to automatically re-embed after rotating into position; Second, the first reset elastic element 73 is a tension spring connecting the rotating ring 72 and the positioning block, used to provide a pull force after the positioning block is lifted so that it automatically engages. The limiting telescopic rod 74 adopts at least a sliding fit inner and outer tube structure or a multi-stage sleeve structure, with its two ends connected to a rotating ring 72 and a positioning block, respectively, to constrain the positioning block's axial movement and prevent wobbling or jamming during circumferential rotation. Through this structure, the positioning block can automatically pop out and re-engage during rotational adjustment, ensuring both smooth gear shifting and reliable locking after engagement.

[0046] Preferably, a modular wire harness anti-foolproof insertion and removal guide device is further provided with a protective ring 8, the inner wall of which is provided with an internal thread; the circumferential surface of the annular mounting base 4 is also provided with an external thread, the external thread being located at the end of the annular mounting base 4 away from the positioning groove 6, the external thread being threadedly connected to the internal thread, so that when the protective ring 8 moves toward the positioning groove 6, the protective ring 8 can cover the positioning mating part 7. Specifically, the protective ring 8 is rotated and tightened with the external thread on the annular mounting base 4 through the internal thread on its inner wall. When the protective ring 8 is screwed toward the positioning groove 6, the end face of the protective ring 8 gradually covers and encloses the outer periphery of the positioning mating part 7, so that the positioned block 20, the positioning groove 6 and the positioning mating part 7 are all in the internal cavity of the protective ring 8, effectively preventing external debris from entering or accidentally touching and causing the positioning block to accidentally dislodge from the groove. When insertion operation is required, the positioning mating part 7 can be exposed by simply rotating the protective ring 8 in the opposite direction for angle adjustment, which is convenient to operate and provides reliable protection.

[0047] Preferably, the positioning block has a pressing part 9, which extends radially along the annular mounting base 4 so that when the protective ring 8 moves toward the positioning groove 6, the protective ring 8 can press the pressing part 9. Specifically, the pressing part 9 is configured as a boss or flange extending radially outward from the positioning block body along the annular mounting base 4. When the protective ring 8 is rotated toward the positioning groove 6, the end face or inner step surface of the protective ring 8 gradually presses against the outer side of the pressing part 9, forcing the positioning block to overcome the elastic force of the first reset elastic member 73 and further press into the positioning groove 6, thereby enhancing the fit between the positioning block and the positioning groove 6 and preventing the positioning block from accidentally coming off under vibration or accidental pulling. This not only improves the device's anti-vibration and anti-loosening capabilities during transportation and storage, but also achieves integrated functions of protective covering and locking reinforcement.

[0048] Preferably, a modular wire harness anti-foolproof insertion and removal guide device further includes a rotary lever 10; the rotary lever 10 is hinged to the rotary ring 72 via a damping shaft and is used for manual operation to drive the rotary ring 72 to rotate. Specifically, the rotary lever 10 is hinged to the outer wall or end face of the rotary ring 72 via a damping shaft, and the damping shaft has a built-in elastic damping element or friction plate, so that the rotary lever 10 can be positioned relative to the rotary ring 72 at any rotation angle. In use, the rotary lever 10 is manually moved to unfold it outward to increase the lever arm, making it easier to apply torque to drive the rotary ring 72 to rotate. After use, the rotary lever 10 can be folded and stored on the surface of the rotary ring 72 to reduce space occupation, and at the same time, it can facilitate the movement of the protective ring 8 to prevent interference and improve the convenience of adjustment operation.

[0049] Preferably, the circumferential surface of the annular mounting base 4 is provided with an annular limiting guide rail 11, the embedding depth of the annular limiting guide rail 11 extends along the circumferential axis of the annular mounting base 4, and rotates with the positioning block around the circumferential axis of the annular mounting base 4. Specifically, the mating structure of the annular limiting guide rail 11 and the positioning block includes at least the following two implementation methods: First, the annular limiting guide rail 11 is configured as a T-shaped groove or dovetail groove opened along the circumferential surface of the annular mounting base 4, and the bottom of the positioning block is correspondingly provided with a T-shaped slider or dovetail slider that matches the cross-sectional shape of the guide rail. The positioning block is embedded in the guide rail by the slider and slides along the guide rail, so that it is always constrained within the guide rail during circumferential rotation, preventing the positioning block from detaching or swaying in the radial direction; Second, the annular limiting guide rail 11 is configured as an annular flange protruding along the circumferential surface of the annular mounting base 4, and the bottom of the positioning block is correspondingly provided with an arc-shaped sliding groove or claw structure that matches the flange. The positioning block rides on the annular flange through the sliding groove and slides along the circumferential direction of the flange to achieve rotation guidance and radial limiting. The above structure ensures the alignment accuracy and relative position stability between the positioning block and each positioning groove 6, while avoiding radial displacement or jamming of the positioning block during rotation due to the force of the first reset elastic element 73, thus improving the smoothness of gear switching and the reliability of engagement positioning.

[0050] Preferably, a modular wire harness anti-misplacement guide device further includes a bolt 12 and a wedge-shaped clamping block 13; the annular mounting base 4 is provided with a mounting hole 14, an internal threaded hole 15 and a guide groove 16; the mounting hole 14 is used to install the anti-misplacement wire harness plug 21; the internal threaded hole 15 extends along the circumferential axis of the annular mounting base 4 and is used to thread-fit with the bolt 12; the guide groove 16 extends radially bidirectionally along the annular mounting base 4 until it communicates with the internal threaded hole 15 and the mounting hole 14 respectively, and slides with the wedge-shaped clamping block 13 so that when the bolt 12 enters the internal threaded hole 15, the bolt 12 pushes the wedge-shaped clamping block 13 to press the gripping part 5 of the anti-misplacement wire harness plug 21. Specifically, the end of the bolt 12 is provided with a conical surface or a spherical surface, and the end of the wedge-shaped clamping block 13 facing the bolt 12 is provided with a conical recess or inclined surface that matches the conical surface. When the bolt 12 is screwed into the internal threaded hole 15, the conical surface at the end of the bolt 12 pushes against the inclined surface of the wedge-shaped clamping block 13, forcing the wedge-shaped clamping block 13 to slide radially along the guide groove 16 toward the mounting hole 14, thereby pressing the outer wall of the gripping part 5 of the foolproof wire harness plug 21 inserted into the mounting hole 14, and realizing the clamping and fixing of the foolproof wire harness plug 21 on the annular mounting base 4.

[0051] Preferably, the annular mounting base 4 is further provided with a reset clearance groove 17 and a second reset elastic member 18; the reset clearance groove 17 extends radially along the annular mounting base 4 and communicates with the guide groove 16; one end of the second reset elastic member 18 is connected to the annular mounting base 4, and the other end is connected to the wedge-shaped clamping block 13, so that when the wedge-shaped clamping block 13 clamps the gripping portion 5 of the foolproof wire harness plug 21, the wedge-shaped clamping block 13 has a gripping portion 5 away from the foolproof wire harness plug 21. Specifically, the second reset elastic element 18 is a compression spring, one end of which abuts against the bottom of the reset clearance groove 17, and the other end abuts against the end face of the wedge-shaped clamping block 13. When the bolt 12 is screwed in and pushes the wedge-shaped clamping block 13 to slide along the guide groove 16 toward the mounting hole 14 to press the gripping part 5, the compression spring is compressed and stores energy, so that the wedge-shaped clamping block 13 always has a reset tendency to move radially away from the gripping part 5. When the bolt 12 is screwed out in the opposite direction, the compression spring releases its elastic force and pushes the wedge-shaped clamping block 13 to automatically retract along the guide groove 16 into the reset clearance groove 17, releasing the clamping state on the gripping part 5, which facilitates the installation or removal of the foolproof wire harness plug 21.

[0052] Preferably, the circumferential surface of the protective ring 8 is provided with anti-slip texture 19, which is used to prevent the hand from slipping out of the foolproof wire harness plug 21 when rotating and plugging / unplugging it. Specifically, the anti-slip texture 19 may be multiple arc-shaped grooves or wavy protrusions distributed circumferentially, adapted to the grip contour of the fingers, allowing the operator's fingers to embed and apply force, thereby providing a stable gripping point when rotating the protective ring 8 to tighten or loosen it, and when holding the protective ring 8 along with the entire device for plugging and unplugging operations, effectively preventing the hand from accidentally slipping out of the surface of the protective ring 8.
