[0027] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments disclosed in the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The embodiment of the present application discloses a cable welding control device for welding a cable, wherein the cable comprises a main connector 1 and at least two sub-connectors 2, wherein the main connector 1 and each sub-connector 2 are connected by a cable, and the embodiment is described by taking a specific cable as an example, wherein the cable comprises a J30J self-contained wire connector (main connector 1), a J27A-17TJL2ⅡH connector (sub-connector 2) and two J27A-53TJL2ⅡH connectors (sub-connectors 2). The J30J self-contained wire connector is connected to a main wiring harness 11, and the main wiring harness 11 is branched into a branch wiring harness 12. In the embodiment, the branch wiring harness 12 comprises a branch wiring harness 1, a branch wiring harness 2 and a branch wiring harness 3, wherein the other end of the branch wiring harness 1 is connected to the J27A-17TJL2ⅡH connector, and the branch wiring harness 2 and the branch wiring harness 3 are respectively connected to two J27A-53TJL2ⅡH connectors.

[0029] A cable welding control device, such as Figure 1 As shown, it includes a substrate 3, on which a main control slot 31 and a sub-control slot 32 are provided. The main connector 1 is placed in the main control slot 31, and the number of the sub-control slots 32 is consistent with the number of types of sub-connectors 2 connected to the main connector 1. The sub-connectors 2 are placed in corresponding sub-control slots 32. In this embodiment, there are two sub-control slots 32, namely the first sub-control slot 32 and the second sub-control slot 32. The J27A-17TJL2ⅡH type connector is placed in the first sub-control slot 32, and the J27A-53TJL2ⅡH type connector is placed in the second sub-control slot 32.

[0030] A main harness control slot 33 and a branch harness control slot 34 are provided on the substrate 3. The branch harness control slot 34 is connected between the main harness control slot 33 and a branch control slot 32. The number of branch harness control slots 34 is consistent with the number of types of branch connectors 2 connected to the main connector 1. In this embodiment, the branch harness control slots 34 include a branch two harness control slot and a branch one harness control slot. The main harness control slot 33 and the branch two harness control slot are colinear and connected between the main control slot 31 and the second sub-control slot 32. The branch one harness control slot is connected to the first sub-control slot 32 from one side of the head end of the branch two harness control slot (the head end is the end close to the main control slot 31). The branch one harness control slot includes a connecting section and a parallel section. One end of the connecting section is connected to the side of the branch two harness control slot close to the end of the main control slot 31, and the other end extends away from the branch two harness control slot. One end of the parallel section is connected to the branch two harness control slot, and the other end is connected to the first sub-control slot 32, and the parallel section is parallel to the branch two harness control slot. Along the direction away from the branch two-wire harness control groove, the side of the connecting section away from the main control groove 31 is inclined toward the direction away from the main control groove 31, so that an acute angle is formed between the side of the connecting section away from the main control groove 31 and the side wall of the branch two-wire harness control groove. In this embodiment, the acute angle is 30°, and the tip of the acute angle is rounded, so that the branch one-wire harness can be more smoothly inserted into the parallel section through the connecting section, and the setting of the rounded corner avoids scratches on the cable at this position.

[0031] The main wiring harness 11 connected by the J30J self-contained wire connector is located in the main control slot 31.

The direction perpendicular to the second sub-control groove 32 and the parallel section is the width direction of the main umbrella-shaped binding area 312; along the direction from the main positioning area 311 to the main control groove 31, the width of the main umbrella-shaped binding area 312 gradually decreases; along the direction from the main positioning area 311 to the main control groove 31, the width of the main harness 11 connected to the J30J self-contained wire connector after binding gradually decreases to match the width of the main control groove 31.

[0033] The sub-control groove 32 includes a sub-positioning area 321 and a sub-umbrella-shaped binding area 322. The sub-umbrella-shaped binding area 322 is connected to the sub-positioning area 321 and the corresponding branch harness control groove 34. The sub-positioning area 321 is used to position and fix the sub-connector 2; along the direction from the branch harness control groove 34 to the sub-positioning area 321, the width of the sub-umbrella-shaped binding area 322 gradually increases. In this embodiment, the first sub-control groove 32 includes a first sub-umbrella-shaped binding area 322 and a first sub-positioning area 321, and the second sub-control groove 32 includes a second sub-umbrella-shaped binding area 322 and a second sub-positioning area 321; after the J27A-17TJL2ⅡH connector and the J27A-53TJL2ⅡH connector are welded to the cable, the cable harness is tied into an umbrella shape to ensure that the cable ends can all be located in the corresponding sub-umbrella-shaped binding area 322, thereby ensuring that the entire cable is located in the groove, ensuring its accurate position, and then ensuring the accuracy of the cable length positioning.
