[0027] As those skilled in the art can fully understand, the features of the different embodiments of the present disclosure can be coupled or combined with each other in part or in whole, and can cooperate with each other in various ways and be driven technically. The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.

[0028] Reference Figures 1 to 5The utility model discloses a terminal wiring detector, including an assembly detection seat 1, on which an assembly hole 3 capable of positioning a female terminal 2 is provided, and on which a detection rod 4, an undercut pressure rod 5 and a terminal limiting rod 6 are provided. The undercut pressure rod 5 is driven by a driving mechanism 1 to punch the undercut on the female terminal 2 so that it is snapped together with a male terminal 7, and the terminal limiting rod 6 is driven by a driving mechanism 2 to move and can be snapped with a step on the female terminal 2 to prevent the female terminal 2 from falling out of the assembly hole 3, and the detection rod 4 can push the male terminal 7 through the drive of a driving mechanism 3.

[0029] The working principle of the above technical solution is as follows: first, the female terminal 2 is manually placed into the assembly hole 3, and then the male terminal 7 is inserted into the female terminal 2, and the driving mechanism 1 is operated to drive the undercut pressure rod 5 to punch the undercut on the female terminal 2 so that it is snapped together with the male terminal 7; then the driving mechanism 2 is operated to drive the terminal limit rod 6 to engage with the step on the female terminal 2 to prevent the female terminal 2 from slipping out of the assembly hole 3, and then the driving mechanism 3 is operated to drive the detection rod 4 to push the male terminal 7. If the undercut is not snapped into place, the male terminal 7 will move under the push of the detection rod 4. By manually detecting whether it moves or taking a photo with a camera to detect whether it moves, defective products that are not properly assembled can be detected.

[0030] As a further structure, it also includes a base 8 and a rotating mechanism. The assembly detection seat 1 is set on the base 8 through a bearing 9, and the assembly detection seat 1 is rotated by the rotating mechanism. For the convenience of the assemblers, we drive the assembly detection seat 1 to rotate through the rotating mechanism before assembly so that the assembly hole 3 faces the operator, which is convenient for the operator to load the material. After the loading is completed, the rotating mechanism drives the assembly detection seat 1 to reset, and then the driving mechanism 1, the driving mechanism 2, and the driving mechanism 3 start working again. The bearing 9 is a commonly used part, so the specific installation structure of the bearing 9 is not described in detail.

[0031] Its specific structure is that the rotating mechanism includes a rotating drive cylinder 10 installed on the base 8, an arc guide hole 11, and a guide plate 12 connected to the rotating drive cylinder 10, wherein the guide plate 12 is provided with a guide groove 13, and the assembly detection seat 1 is provided with a guide rod 14 and a guide wheel 15 rotatably matched with the guide rod 14, wherein the guide wheel 15 is located in the guide groove 13 and the guide rod 14 is located in the arc guide hole 11. Through the above structure, the linear push of the rotating drive cylinder 10 is converted into the rotational motion of the assembly detection seat 1, thereby rotating the assembly detection seat 1. Compared with using a motor or a rotating cylinder to drive the assembly detection seat 1 to rotate, the cost is low, and one side of the guide plate 12 is also provided with a buffer cylinder that is against it. The rotational connection between the guide rod 14 and the guide wheel 15 is a conventional technology, so it is not described in detail.

[0032] As shown in the figure, the driving mechanism 1 includes a stamping cylinder 16 installed on the assembly detection seat 1, and the assembly detection seat 1 is provided with a top hole 17 that penetrates the assembly hole 3. The undercut pressure rod 5 is connected to the stamping cylinder 16 and is stamped through the top hole 17. As a further structure, the undercut pressure rod 5 is connected to the stamping cylinder 16 through a stamping frame 18. The assembly detection seat 1 is provided with a frame groove 19, and the stamping frame 18 can move in the frame groove 19. The stamping frame 18 has two side rods arranged opposite to each other, and the whole is in an inverted concave shape. One side rod is connected to the undercut pressure rod 5, and a buffer spring 20 is provided between the other side rod and the assembly detection seat 1 to prevent the undercut pressure rod 5 from being too much of an impact force that may damage the terminal.

[0033] As shown in the figure, the second driving mechanism includes a limit cylinder 21 installed on the assembly detection seat 1, and the assembly detection seat 1 is provided with a limit hole 22 that penetrates the assembly hole 3. The terminal limit rod 6 is connected to the limit cylinder 21 and is locked with the step on the female terminal 2 through the limit hole 22, so as to prevent the female terminal 2 from being driven out of the assembly hole 3 when the detection hole pushes the male terminal 7. As a further structure, the second driving mechanism also includes a connecting rod 23, one end of which is hinged to the assembly detection seat 1 and connected to the terminal limit rod 6, and the other end of the connecting rod 23 is provided with a long hole (not shown in the figure), and the limit cylinder 21 is provided with a connecting seat 24, and a guide shaft (not shown in the figure) is provided in the connecting seat 24, and the guide shaft is located in the long hole. The above structure is converted into the linear movement of the limit rod through the swing of the connecting rod 23. Since there is no installation position above the assembly detection seat 1, the limit cylinder 21 can only be installed on the side of the assembly detection seat 1, but the terminal limit rod 6 needs to move downward from the top of the assembly detection seat 1 to a position where it can be engaged with the step on the female terminal 2. We adopt the above structure to convert the linear movement of the limit cylinder 21 into the linear movement of the terminal limit rod 6 through the swing of the connecting rod 23.

[0034] As shown in the figure, the driving mechanism three includes a detection cylinder 27 installed on the assembly detection seat 1, and the assembly detection seat 1 is provided with a detection hole 28 that penetrates the assembly hole 3. The detection rod 4 is connected to the detection cylinder 27 and pushes the male terminal 7 through the detection hole 28. As a further preferred structure, since the impact force of the cylinder is relatively large, it is easy to knock out the assembled male terminal 7, and therefore the assembly detection seat 1 is provided with a sliding hole 29 and a slider 30 cooperating with the sliding hole 29, and the detection hole 28 is located in the slider 30, and a reset spring 31 and a limiting boss are provided in the detection hole 28, and a rod cap is provided on the detection rod 4, one end of the reset spring 31 abuts against the rod cap and the other end abuts against the limiting boss, and the end of the detection hole 28 adjacent to the cylinder is closed by an end plate 32 to prevent the detection rod 4 from falling out, and the slider 30 is connected to the detection cylinder 27. Through the above structure, the impact force of the cylinder can be buffered by the reset spring 31 and then act on the detection rod 4, and the reset spring 31 can also reset the detection rod 4 to avoid damage to the terminal.

[0035] As shown in the figure, it also includes a clamping seat 33 and a wire clamp seat 34. The clamping seat 33 is provided with a clamp 35 for clamping the wire harness, and the wire clamp seat 34 is provided with a wire clamp positioning groove 36. After completing the assembly inspection of the female terminal 2 and the male terminal 7, we install the wire clamp 37 at the predetermined position on the terminal wire. The wire harness is clamped by the clamp 35, and the wire clamp 37 is positioned by the wire clamp positioning groove 36. We can install the wire clamp 37 at the predetermined position. The wire clamp 37 is a conventional product, so the specific structure is not described in detail.

[0036] The above is a detailed introduction to a terminal wiring detector provided by an embodiment of the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
