Description

Technical Field

[0001] This invention relates to the field of wire harness assembly technology, and more specifically to a connector and wire harness assembly with high pull-out force. Background Technology

[0002] Existing high pull-out force connectors mainly employ two structures: snap-fit ​​and push-push. The snap-fit ​​structure is simple and achieves both high pull-out force and a secure connection; however, when separating the male and female ends, the snap-fit ​​needs to undergo significant elastic deformation, leading to difficulties in separation or easy damage during operation. The push-push structure, as an improvement on the snap-fit ​​structure, significantly improves the ease of insertion and removal with its unique locking method; however, its unlocking mechanism relies on the relative sliding displacement of the male and female ends. This characteristic makes it difficult to arrange properly in scenarios with protective structures such as dust covers due to the obstruction of the protective structures. Therefore, it is necessary to design a push-push structure that can be linked to automatically open the protective structure before insertion and removal operations, balancing ease of operation and protective performance.

[0031] The present invention will be further described in conjunction with the following embodiments.

[0032] Depend on Figures 1 to 10 As can be seen, the high pull-out force connector described in this embodiment includes a female end base 1 and a housing 2; the housing 2 is provided with a receiving cavity 21; the female end base 1 is disposed in the receiving cavity 21; the female end base 1 is provided with a conductive sleeve 11; the top of the conductive sleeve 11 is provided with a plug interface 12; the female end base 1 is provided with a rotating seat 3 for lifting and rotating; the rotating seat 3 is provided with a valve plate 31 for shielding the plug interface 12; the top of the receiving cavity 21 is provided with a locking ring 41; a connecting rod 33 is provided between the locking ring 41 and the rotating seat 3; the top of the housing 2 is provided with a driving groove 22; a cylindrical latch 43 is rotatably provided in the driving groove 22; the cylindrical latch 43 has a locking groove 44; the locking ring 41 drives the cylindrical latch 43 to rotate. The male end base 7 is provided with a receiving cavity 71; the receiving cavity 71 is movably provided with a conductive terminal 72; a sealing ring 73 is provided between the conductive terminal 72 and the receiving cavity 71; a plug seat 8 is movably provided within the receiving cavity 71; the conductive terminal 72 is connected to the plug seat 8; a drive seat 9 for driving the plug seat 8 to move up and down is movably provided within the receiving cavity 71; a fixed rod 92 is hinged to the drive seat 9; a movable rod 93 is movably provided at the bottom of the fixed rod 92; a locking block 95 that cooperates with the locking groove 44 is provided at the bottom of the fixed rod 92.

[0033] Specifically, in the high pull-out force connector described in this embodiment, when idle, the valve plate 31 covers the insertion interface 12 of the conductive sleeve 11 to prevent dust and moisture from entering the conductive sleeve 11; at the same time, the conductive terminal 72 is housed in the receiving cavity 71 to prevent dust and moisture from damaging the conductive terminal 72.

[0034] When the female base 1 and the male base 7 are connected, the locking block 95 at the bottom of the movable rod 93 is first inserted into the locking groove 44 of the cylindrical lock buckle 43. Then, the male base 7 pushes the rotating seat 3 to move downward. During the downward movement of the rotating seat 3, it rotates at the same time, thereby driving the locking ring 41 to rotate synchronously through the connecting rod 33. While the rotating seat 3 is rotating, the valve plate 31 opens. In addition, when the locking ring 41 rotates, it drives the cylindrical lock buckle 43 and the locking block 95 to rotate. The locking block 95 drives the drive seat 9 to move through the movable rod 93 and the fixed rod 92. During the movement of the drive seat 9, it drives the plug seat 8 and the conductive terminal 72 to move downward, so that the conductive terminal 72 is inserted into the plug interface 12 of the conductive sleeve 11, thus completing the connection between the female base 1 and the male base 7.

[0035] This embodiment describes a connector with high pull-out force. The locking ring 41 has a driving spiral groove 42 on its side wall; a cylindrical latch 43 is sleeved on the locking ring 41; the cylindrical latch 43 has a driving pin 45; and the driving pin 45 is movably disposed within the driving spiral groove 42. Through this arrangement, during the rotation of the locking ring 41, the driving spiral groove 42 and the driving pin 45 can drive the cylindrical latch 43 to rotate, thereby causing the locking block 95 to move the driving seat 9 via the movable rod 93 and the fixed rod 92.

[0036] In this embodiment, a connector with high pull-out force is described. The valve plate 31 is movably disposed on the rotating seat 3 along the diameter direction of the rotating seat 3. The female end base 1 is provided with an involute groove 13. The valve plate 31 is provided with a limiting pin 32, which is movably disposed within the involute groove 13. Through this arrangement, during rotation of the rotating seat 3, the involute groove 13 and the limiting pin 32 cooperate to allow the valve plate 31 to move along the diameter direction of the rotating seat 3, thereby shielding or opening the insertion interface 12 of the conductive sleeve 11.

[0037] In this embodiment, a connector with high pull-out force is provided, wherein a first spring 34 is provided between the bottom of the rotating seat 3 and the female end base 1. This arrangement facilitates the reset of the rotating seat 3.

[0038] This embodiment of a connector with high pull-out force includes a linkage groove on the inner wall of the female base 1; a floating pin 35 is movably provided on the outer wall of the rotating seat 3; the floating pin 35 is movably disposed in the linkage groove. The linkage groove includes a first spiral groove 51, a second spiral groove 52, a first vertical groove 53, and a second vertical groove 54; the top of the first vertical groove 53 communicates with the top of the first spiral groove 51; the bottom of the first vertical groove 53 communicates with the top of the second spiral groove 52; the top of the second vertical groove 54 communicates with the bottom of the first spiral groove 51; the bottom of the second vertical groove 54 communicates with the bottom of the second spiral groove 52; the top of the first vertical groove 53 has a first inclined surface 61 and a first blocking boss 62; the bottom of the first spiral groove 51 has a second inclined surface 63 and a second blocking boss 64; the bottom of the second vertical groove 54 has a third inclined surface 65 and a third blocking boss 66.

[0039] This embodiment of a wire harness assembly includes a male base 7 and a connector with high pull-out force; the male base 7 is provided with a receiving cavity 71; the receiving cavity 71 is movably provided with a conductive terminal 72; a sealing ring 73 is provided between the conductive terminal 72 and the receiving cavity 71; a plug seat 8 is movably provided within the receiving cavity 71; the conductive terminal 72 is connected to the plug seat 8; a drive seat 9 for driving the plug seat 8 to move up and down is movably provided within the receiving cavity 71; a fixed rod 92 is hinged to the drive seat 9; a movable rod 93 is movably provided at the bottom of the fixed rod 92; a locking block 95 that cooperates with a locking groove 44 is provided at the bottom of the fixed rod 92. In this embodiment of the wire harness assembly, the drive seat 9 is horizontally slidably disposed in the receiving cavity 71; one end of the drive seat 9 is provided with a first drive inclined surface 91; the top of the plug seat 8 is provided with a second drive inclined surface 81 that cooperates with the first drive inclined surface 91; the top of the fixed rod 92 is hinged to the other end of the drive seat 9; a second spring 82 is provided between the bottom of the plug seat 8 and the bottom of the receiving cavity 71; a third spring 94 is provided between the fixed rod 92 and the movable rod 93. In this embodiment of the wire harness assembly, the top of the male end base 7 is movably provided with an unlocking cover 96; a fourth spring 97 is provided between the unlocking cover 96 and the male end base 7; the unlocking cover 96 is connected to an unlocking rod 98 for abutting against the rotating seat 3.

[0040] Specifically, in the wire harness assembly described in this embodiment, when idle, the valve plate 31 covers the insertion interface 12 of the conductive sleeve 11 to prevent dust and moisture from entering the conductive sleeve 11; at the same time, the conductive terminal 72 is housed in the receiving cavity 71 to prevent dust and moisture from damaging the conductive terminal 72; in addition, under the action of the first spring 34, the floating pin 35 is located at the top of the first spiral groove 51; in addition, under the action of the second spring 82, the plug seat 8 is located at the top of the receiving cavity 71, so that the conductive terminal 72 is housed in the receiving cavity 71.

[0041] When the female base 1 and the male base 7 are connected, the locking block 95 at the bottom of the movable rod 93 is first inserted into the locking groove 44 of the cylindrical latch 43. Then, the male base 7 pushes the rotating seat 3 downward. At this time, the floating pin 35 moves along the first spiral groove 51, causing the rotating seat 3 to rotate simultaneously as it moves downward. With the cooperation of the involute groove 13 and the limiting pin 32, the valve plate 31 opens while the rotating seat 3 rotates. In addition, the rotating seat 3 drives the locking ring 41 to rotate synchronously through the connecting rod 33. When the locking ring 41 rotates, it drives the cylindrical latch 43 to rotate through the cooperation of the spiral groove and the driving pin 45. Since the locking groove 44 is locked with the locking block 95, during the rotation of the cylindrical lock 43, the locking block 95 drives the drive seat 9 to move inward through the movable rod 93 and the fixed rod 92. With the cooperation of the first drive inclined surface 91 and the second drive inclined surface 81, the drive plug seat 8 and the conductive terminal 72 move downward, so that the conductive terminal 72 is inserted into the plug interface 12 of the conductive sleeve 11. When the floating pin 35 moves to the top of the second vertical groove 54, under the action of the second blocking boss 64 and the first spring 34, the floating pin 35 is locked at the top of the second vertical groove 54, thereby completing the installation of the female end base 1 and the male end base 7.

[0042] When it is necessary to separate the female base 1 from the male base 7, the unlocking cover 96 is pressed down, and the unlocking cover 96 pushes the rotating seat 3 downward through the unlocking rod 98. At this time, the floating pin 35 moves to the bottom of the second vertical groove 54. After the unlocking cover 96 is released, the floating pin 35 moves upward along the second spiral groove 52 under the action of the first spring 34, so that the rotating seat 3 rotates in the opposite direction until the floating pin 35 moves to the top of the first vertical groove 53, and all components are reset, thereby completing the separation of the female base 1 from the male base 7.

[0043] In the wire harness assembly described in this embodiment, the bottom of the conductive terminal 72 is provided with a protective cover 74. This design prevents moisture from entering the receiving cavity 71 when the conductive terminal 72 is housed within it.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
