The cable end connector 11 features a locking mechanism with a hook 111 at the front end. A pull ring 112 has a protrusion at the front end that fits within hook 111. To attach the rubber ring to this cable end connector, the pull ring 112 must be pulled to raise hook 111, allowing the rubber ring 113 to fit over the connector 114, just below hook 111. Currently, assembly and rework of the rubber rings for this type of connector are largely manual, a laborious process with significant impact on quality. This can lead to issues such as improper assembly, poor consistency, and rubber ring damage. Utility Model Content

DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] The utility model discloses a rubber ring auxiliary tool for assembling rubber rings on wiring harnesses. Figure 2-7As shown, it is a preferred embodiment of the present utility model, which may include a base plate 2, a slide rail 31 and a slider 32, a positioning block 4 for fixing the wiring harness 1, a push-pull mechanism 5, a pulling mechanism 6 for the pull ring 112 for pulling the wiring harness, and a rubber ring pushing mechanism 7; the slide rail 31, the push-pull mechanism 5, and the pulling mechanism 6 are respectively installed on the base plate 2, the slider 32 is slidably installed on the slide rail 31, the positioning block 4 is installed on the slider 32, the push-pull mechanism 5 drives the slider 32 to move back and forth along the wiring harness with the positioning block 4, and the rubber ring pushing mechanism 7 is provided with a guide hole 74 adapted to the wiring harness wire end connector joint.

[0031] The positioning block 4 has a mounting groove 41 that can clamp the wire end connector 1 and is used to fix the wire end connector. At the same time, the direction of the wire harness 1 after fixation is consistent with the sliding direction of the slider 32.

[0032] The push-pull mechanism 5 can be a side-pushing toggle clamp comprising a push rod 51 and a handle 52 for causing the push rod 51 to perform linear reciprocating motion. The push rod 51 is directly or indirectly connected to the slider 32. To facilitate the connection between the slider 32 and the push-pull mechanism 5, the slider 32 can be further provided with an extension plate 33, through which the slider 32 is fixedly connected to the positioning block 4 and the push-pull mechanism 5, respectively. Specifically, the extension plate 33 is provided with a mounting hole 331, into which the end of the push rod 51 is fixed. A compression spring 53 can be further mounted on the push rod to provide a buffering effect, preventing failure of components such as the pull ring 112 and causing secondary damage.

[0033] The pulling mechanism 6 may include a pull post 61 and a pull plate 62. The pull plate 62 is fixed to one side of the slide rail 31 on the base plate 2. The pull post 61 is disposed on the pull plate 62 and aligned with the mounting groove 41 of the positioning block 4, thereby pulling the pull ring 112 of the wire end connector 11. In this embodiment, the positioning block 4 is located directly above the slider 32, so the pull plate 62 is required to assist in aligning the pull post 61 with the mounting groove 41. If the positioning block 4 is located above and to the side of the slider 32, the pull plate 62 may not be required. The pull post 61 can be vertically fixed to the base plate 2 to align with the mounting groove 41, facilitating pulling of the pull ring 112. The pulling mechanism 6 may also employ a hook or other structure, but for ease of operation, this embodiment preferably employs a pull post 61 of a certain length.

[0034] The rubber ring pushing mechanism 7 can include a handle 71, a guide plate 72, and a pry plate 73. The handle 71 facilitates exerting force. The guide plate 72 is fixed to the front end of the handle 71. A guide hole 74, whose shape is adapted to the connector 114 of the wire end connector 11, passes through the handle 71 and the guide plate 72. The pry plate 73 is embedded in the lower edge of the guide hole on the guide plate 72. The pry plate 73 is pointed and protrudes out of the guide hole 74. For easy installation, the pry plate 73 can be integrally formed on a mounting plate that is embedded in the guide plate 72. The pry plate 73 holds and pries up the hook 111 a second time, making the operation of inserting the rubber ring easier. At the same time, because it protrudes out of the guide hole, it has a pushing and limiting function.

[0035] Furthermore, if Figure 6-7 As shown, a backing plate 81 can be installed between the slide rail 31 and the base plate 2 to elevate the slider 32 and extension plate 33. A pair of fixing posts 82 are provided below the push rod 51. One fixing post 82 is fixedly attached to the lower edge of the extension plate 33, and the other fixing post 82 is fixedly attached to the base plate 2. A tension spring 83 is installed between the two fixing posts 82. After the rubber ring is installed, the tension spring 83 assists in resetting the push rod, slider, and positioning block, and maintains the position of the handle 52, keeping the side-push toggle clamp in the open state.

[0036] Furthermore, if Figure 2 、 Figure 4 As shown, the slider 32 may also be provided with a limit block 91 and a limit seat 92 on the other side of the slider 32 relative to the push-pull mechanism 5, which are used to prevent the pull ring from being over-pulled and protect the wiring harness product. The limit block 91 is fixedly connected to the extension plate 33 or the slider 32, and the limit seat 92 is fixedly connected to the bottom plate 2 and is provided with a limit groove 921, and the limit block 91 is placed in the limit groove 921. Specifically, the limit block 91 is T-shaped, and the limit seat 92 is U-shaped. The U-shaped opening is the limit groove 921, and a limit screw 922 (wherein Figure 2 The limiting screw 922 is not shown), and the limiting block 91 can be further limited by adjusting the limiting screw 922.

[0037] The auxiliary tooling of the present invention is used to put the rubber ring on the connector 114 of the wire end connector 11 when producing or reworking the wire harness product. Figure 6 As shown, in the initial state, the side push toggle clamp is in the open state, that is, the handle 52 is turned downward to the horizontal position, and the push rod 51 is retracted. Figure 7As shown, the wire harness 1 is placed with the pull ring 112 facing downward in the positioning block 4 as shown in the figure. The pull ring 112 is placed on the pull column 61. The handle 52 is turned upward until the side push toggle clamp is in the closed state. The push rod 51 is then pushed to the left, driving the extension plate 33, the slider 32, the positioning block 4 and the wire harness 1 to slide along the slide rail 31 in the opposite direction of the pull column 61. At this time, because the pull column 61 is stationary, the pull ring 112 on the pull column 61 is pulled, and the hook 111 is lifted up by the protrusion at the front end of the pull ring 112, thereby vacating the assembly position reserved for the rubber ring. The rubber ring is then pre-placed on the connector 114 of the line end connector 11, and the rubber ring pushing mechanism 7 is used to push the rubber ring to the required assembly position. During this process, the guide hole 74 is aligned with the connector 114 and pushed to the right. The connector 114 gradually enters the guide hole 74. During the push, the pry plate 73 first contacts the hook 111, prying the hook 111 again and keeping the prying state stable. Finally, after the rubber ring is smoothly pushed to the assembly position, the rubber ring pushing mechanism 7 is withdrawn and the side-pushing toggle clamp is opened. At this time, the tension spring 83 will keep the handle 52 in place, and the pull ring 112 will be freed from the pull column 61 without force, and the wire harness with the rubber ring can be removed. The auxiliary tooling of the utility model uses a mechanical device to replace the manual pulling of the pull ring and the rubber ring, which reduces the difficulty of operation and avoids the operator's problems such as improper assembly, poor consistency and rubber ring damage that affect the stability of the wire end connector during use.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any changes or modifications made according to the claims and description of the present invention should fall within the scope of the present invention patent.
