Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a quick-connect cable structure. Background Technology

[0002] With the increasing functionality of automobiles and the widespread application of electronic control technology, there are more and more electrical components and wires. The number of circuits and power consumption in automobiles have increased significantly, making wiring harnesses thicker and heavier. This presents a major problem: how to arrange a large number of wiring harnesses more effectively and rationally within the limited space of an automobile, so as to enable the wiring harnesses to perform greater functions, has become a challenge for the automotive manufacturing industry.

[0003] A tightening tensile-resistant cable connector disclosed in patent CN220527665U includes a connector body, a sealing ring fixed above the connector body, a fixing nut fixed above the sealing ring, a locking nut above the connector body, a clamping nut above the locking nut, a limiting groove inside the clamping nut, a bellows fixed above the clamping nut, and a cable fixed inside the bellows. The improved cable connector extends the existing clamping nut of the traditional cable connector, reduces the internal thread length of the clamping nut, adds a smooth surface to accommodate the clamping ring, and adds a limiting groove to accommodate a retaining ring. The clamping nut presses downwards to clamp the bellows, while the retaining ring presses downwards to lock and hold the bellows. This double clamping of the bellows locks the cable, preventing it from falling out, and also enhances the tensile strength of the cable connector.

[0004] In the above solution, the addition of retaining rings and extended tightening nuts enhances the tensile strength and prevents the risk of corrugated pipe detachment. However, in situations where the interior space is limited, problems may arise in the spatial arrangement of cable connection ends and the handling of cables in confined spaces. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems by providing a quick-connect cable structure that can solve the technical issues described above.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The cable quick-connect structure includes a male connector and a female connector. The male connector is provided with an access cylinder that fits into an access cavity opened inside the female connector. Several locking heads are provided on the outer periphery of the access cylinder. The locking heads enter axially into locking grooves opened on the inner wall of the access cavity and move axially between the locking grooves in a locked position and an unlocked position through the male and female connectors.

[0007] In the aforementioned cable quick-connect structure, the locking groove includes a first abutment wall and a second outer abutment wall that are axially opposite each other. The locking position and the unlocking position are circumferentially staggered on one side of the first abutment wall. The second outer abutment wall is provided with a plurality of second guide protrusions that are axially corresponding to adjacent locking and unlocking positions.

[0008] In the aforementioned cable quick-connect structure, the second guide protrusion includes an inclined second guide surface and a second stop surface parallel to the axis, and the lock head slides obliquely on the second guide surface and then abuts against the second stop surface.

[0009] In the aforementioned cable quick-connect structure, the lock head is provided with a second sliding surface. When the male plug and the female plug move toward each other, the second sliding surface slides along the second guide surface and abuts against the second stop surface at the end.

[0010] In the aforementioned cable quick-connect structure, the first abutment wall is further provided with a first guide surface that connects the locking position and the unlocking position. Each of the first guide surfaces is inclined to the same side and slides in contact with the lock head.

[0011] In the aforementioned cable quick-connect structure, the lock head is provided with a first sliding surface. When the male plug and the female plug move in opposite directions, the first sliding surface enters the locking position or unlocking position along the first guide surface.

[0012] In the aforementioned cable quick-connect structure, a rotating ring is circumferentially rotatably provided on the outer arc surface of the access cylinder, and the locking head is disposed on the rotating ring.

[0013] In the aforementioned cable quick-connect structure, a connector is provided in the access cavity, and the connector is fitted into the inner ring of the access cylinder with a clearance and is connected to a contact shaft provided therein.

[0014] In the aforementioned cable quick-connect structure, the inner ring of the access cylinder is provided with a pre-tightening baffle that slides by being pushed by a spring, and the pre-tightening baffle abuts against one end of the plug hole of the plug socket.

[0015] In the aforementioned cable quick-connect structure, the pre-tightening baffle has an axially formed through hole, through which the contact shaft passes.

[0016] The advantages of this utility model are: The connection between the male and female connectors can be completed with only an axial insertion action. The female connector has a locking groove that matches the lock head on the male connector. By pressing the male and female connectors against each other, the lock head slides and rotates to the locked position to complete the connection. Pressing again causes the lock head to slide and rotate to the unlocked position to complete the separation. This allows for convenient and quick connection and disconnection of cables even in a limited vehicle interior space. Attached Figure Description

Detailed Implementation

[0023] The following are specific embodiments of the utility model, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the utility model. However, the utility model is not limited to these embodiments.

[0024] like Figures 1-4 As shown, the cable quick-connect structure includes a male connector 1 and a female connector 2. The male connector 1 is provided with an access cylinder 11 that fits into an access cavity 21 opened inside the female connector 2. A plurality of locking heads 12 are provided on the outer periphery of the access cylinder 11. The locking heads 12 enter axially into locking grooves 3 opened on the inner wall of the access cavity 21, and move axially between the locking position 31 and the unlocking position 32 of the locking groove 3 through the male connector 1 and the female connector 2.

[0025] That is, the male connector is inserted into the cavity of the female connector through the access cylinder. During the insertion process, the locking head rotates to align with the axial direction of the locking groove, and then slides into the locking groove of the female end after being pulled in the opposite direction. The locking head is locked in the locking position to form a mechanical lock. If it needs to be pulled out, the two connectors are moved towards each other again so that the locking head slides to the position corresponding to the unlocking position. Then the connectors can be separated by moving them back and forth.

[0026] In this embodiment, the locking groove 3 includes a first abutting wall and a second outer abutting wall that are axially opposite each other. The locking position 31 and the unlocking position 32 are arranged alternately on one side of the first abutting wall. The second abutting wall is provided with a plurality of second guide protrusions that are axially corresponding to adjacent locking positions 31 and unlocking positions 32.

[0027] The inner wall of the female connector adopts a stepped double-layer structure. One layer forms a locking groove, and the other layer provides a guiding path. The locking head contacts and is constrained by the inner wall of the access cavity 21 along the insertion and removal path and the access cylinder 11 along the inner wall of the access cavity 21, ensuring accurate movement trajectory.

[0028] The locking groove 3 is divided into a first abutting wall and a second outer abutting wall in the axial direction. The first abutting wall contacts the lock head when the two connecting ends move in opposite directions, while the second outer abutting wall contacts the lock head when the two connecting ends move towards each other.

[0029] In this embodiment, the second guide protrusion includes an inclined second guide surface 33 and a second stop surface 34 parallel to the axis. The lock head 12 slides obliquely on the second guide surface 33 and then abuts against the second stop surface 34.

[0030] When the male end is pushed forward, the lock head contacts the second guide surface, is gradually pressed in and slides along the inclined surface, and finally forms an axial position at the stop surface, so that the lock head 12 moves from the position corresponding to the unlock position 32 to the position corresponding to the lock position 31.

[0031] In this embodiment, the lock head 12 is provided with a second sliding surface 15. When the male plug end 1 and the female plug end 2 move towards each other, the second sliding surface 15 slides along the second guide surface 33 and abuts against the second stop surface 34 at the end.

[0032] The lock head 12 has a plane with the same tilt angle as the second guide surface 33. During the movement of the two connecting ends toward each other, the friction contact surface causes the lock head to move on a controlled path.

[0033] In this embodiment, the first abutting wall is also provided with a first guide surface 35 that connects the locking position 31 and the unlocking position 32. Each first guide surface 35 is inclined to the same side and slides in contact with the lock head 12.

[0034] When the male plug 1 and the female plug 2 move in opposite directions, the lock head slides obliquely along the first guide surface and gradually enters the locking position 31 or the unlocking position 32.

[0035] In this embodiment, the lock head 12 is provided with a first sliding surface 13. When the male plug end 1 and the female plug end 2 move in opposite directions, the first sliding surface 13 enters the locking position 31 or the unlocking position 32 along the first guide surface 35.

[0036] The lock head and the first guide surface form an inclined fit, providing a controlled disengagement path during the pulling process. This enables a quick connection function that can be completed by axial movement of the two connecting ends, significantly simplifying the operation steps and making it convenient to operate even in confined spaces.

[0037] In this embodiment, a rotating ring 14 is circumferentially rotatable on the outer arc surface of the access cylinder 11, and a lock head 12 is disposed on the rotating ring 14.

[0038] The rotating ring is fixed to the outside of the cylinder through a slot. It can rotate in the circumferential direction to drive the lock head to rotate around the cylinder. During unlocking and locking operations, it moves independently of the connecting end, so that the two connecting ends will not produce relative axial rotation. Unlike a single contact shaft that can rotate in the contact hole, it is more suitable for multi-contact shaft connection structures.

[0039] In this embodiment, a plug-in seat 22 is provided in the access cavity 21. The plug-in seat 22 is fitted into the inner ring of the access cylinder 11 with a clearance and is plugged into the contact shaft 18 provided therein.

[0040] The connector is an insulated structural component with an internal metal contact shaft installed in the female end cavity. After the male end is inserted, the contact shaft achieves conductive connection by mating with the inner ring of the insertion cylinder and the outer arc surface of the connector.

[0041] In this embodiment, a pre-tightening baffle 17 is provided on the inner ring of the access cylinder 11, which is pushed and slid by a spring 16. The pre-tightening baffle 17 abuts against one end of the insertion hole of the insertion seat 22.

[0042] The spring is installed inside the cylinder cavity. After insertion, the pre-tightening baffle applies pressure forward to cooperate with the locking structure to pre-tighten and maintain tight contact between the conductive ends. This allows the connection end to automatically compensate for the insertion gap, preventing loosening and ensuring the stability of the lock head in the locking position 31. At the same time, under the action of the spring and the baffle, the lock head 12 always moves towards the first abutment wall side, so that locking and unlocking of the connection end can be completed by applying axial compressive force.

[0043] In this embodiment, the pre-tightening baffle 17 has an axial through hole, through which the contact shaft 18 passes.

[0044] The through hole is centered to ensure that the contact shaft and the baffle move coaxially to prevent misalignment, and to make the contact end accurately aligned to reduce contact resistance.

[0045] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
