Integrated connectors connect multiple connectors to a junction box through cables, and then the junction box is completed by injection molding. Therefore, all cables need to be connected to the junction box before injection molding. However, there are many connectors on the integrated connector, resulting in a lot of cables for connection. These cables are very easy to get confused or even entangled when connected to the junction box. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See attached Figure 1 The utility model provides a wire clamping fixture, including a U-shaped clamping plate 1, a first wire clamping group 2 and a second wire clamping group 3 are respectively arranged on both sides of the clamping plate 1, a third wire clamping group 4 is arranged on the rear side of the clamping plate 1, the first wire clamping group 2 includes a plurality of side holes 21 arranged on the upper end surface of the clamping plate 1, a first limit block 22 and a second limit block 23 are respectively fixed on both sides of the side hole 21, and the distance between the first limit block 22 and the second limit block 23 is greater than the distance between the lower ends; the cable 9 is clamped from top to bottom between the first limit block 22 and the second limit block 23, and then falls into the side hole 21, The cable 9 is restricted in the side hole 21 by the first limit block 22 and the second limit block 23, but the cable 9 can be pulled freely in the side hole 21 to facilitate the adjustment of the length of the cable 9 in the junction box 8, thereby facilitating the installation of the cable 9. The first limit block 22 and the second limit block 23 constitute a limit group, and the limit groups of two adjacent side holes 21 are staggered. The structure of the second clamping group 3 and the structure of the third clamping group 4 are the same as the structure of the first clamping group 2. The side holes 21 of the first clamping group 2, the side holes 21 of the second clamping group 3 and the extension lines of the side holes 21 of the third clamping group 4 intersect in the clamping plate 1. The utility model fixes the cable 9 on the first clamping group 2, the second clamping group 3 and the third clamping group 4 in sequence, and the cable 9 can be pulled freely in the side hole 21, which facilitates the connection of the cable 9 to the junction box 8. Refer to the attached Figure 4 , when all cables 9 are connected, all cables 9 and the junction box 8 are pushed into the mold 100 for injection molding through the jig. At this time, the mold 100 is in the U-shaped groove of the card plate 1 (the jig itself does not enter the mold 100). After the injection molding is completed, all cables 9 can be pulled out from the side holes 21. The overall structure of the utility model is simple. When wiring in the junction box 8, the first limit block 22 and the second limit block 23 limit the cables 9 in the side holes 21, which can effectively prevent confusion and entanglement. The jig can quickly push the cables 9 and the junction box 8 into the mold 100 together, which is efficient. Third, the design of the first limit block 22 and the second limit block 23 also facilitates the cables 9 to quickly detach from the side holes 21.

[0024] As another embodiment of the present invention: Figure 2The first limiting block 22 and the second limiting block 23 are both provided with an arc surface 221 adapted to the side hole 21 . This structural design facilitates adaptation to the outer surface of the cable 9 .

[0025] As another implementation of the utility model: there are two limit groups on each side hole 21, and the four limit groups on two adjacent side holes 21 are staggered. This structural setting can better limit the cable 9 in the side hole 21.

[0026] Specifically, the side hole 21 is a semicircular hole.

[0027] As another embodiment of the present invention: a handle 5 is fixed to the rear end of the card plate 1 , and this structural design facilitates pushing the cable 9 and the junction box 8 into the mold 100 through the handle 5 .

[0028] An implementation method of fixing the handle 5 to the card plate 1: the handle 5 is fixed to the card plate 1 through a connecting plate 7, and the connecting plate 7 is U-shaped. In this structural design, a gap is provided between the connecting plate 7 and the card plate 1 to facilitate the passage of the cable 9.

[0029] As another embodiment of the present invention: a leg 6 is fixed to the bottom of the card board 1, and the leg 6 can support the card board 1 at a higher level so that the card board 1 and the mold 100 can be roughly flush. When the mold 100 enters the card board 1, the cable 9 and the junction box 8 can be more conveniently pushed into the mold 100.

[0030] As another embodiment of the present invention: Figure 2 A first avoidance groove 11 is provided on both sides of the card board 1. When the mold 100 enters the card board 1, both sides of the mold 100 are in contact with the card board 1. This setting can reduce the contact area between the card board 1 and the mold 100.

[0031] As another embodiment of the present invention: a second avoidance groove 12 is provided on the rear side of the pallet 1. When the mold 100 enters the pallet 1, the rear side of the mold 100 contacts the pallet 1. This arrangement can reduce the contact area between the pallet 1 and the mold 100.

[0032] As another implementation of the present utility model: the supporting legs 6 are arranged at the notch of the first avoidance groove 11 and the notch of the second avoidance groove 12 .

[0033] An implementation method of fixing the connecting plate 7 to the clamping plate 1: a clamping slot 71 matching with the clamping plate 1 is provided at the front end of the connecting plate 7. After the clamping plate 1 is inserted into the clamping slot 71, the clamping slot 71 and the clamping plate 1 are fixed by bolts.

[0034] As another embodiment of the present utility model: an H-shaped groove is provided at the rear end of the connecting plate 7, and a plug 51 matching with the H-shaped groove is provided on the handle 5. The plug 51 and the connecting plate 7 are fixed by bolts. The provision of the H-shaped groove and the plug 51 enables the connecting plate 7 and the handle 5 to be more firmly connected together.

[0035] As another embodiment of the present utility model: weight-reducing grooves 72 are provided on both the inner and outer sides of the connecting plate 7. This setting helps to reduce the weight of the jig.

[0036] As another embodiment of the present utility model: some of the side holes 21 in the first wire clamping group 2 have relatively large diameters, some of the side holes 21 in the second wire clamping group 3 have relatively large diameters, and some of the side holes 21 in the third wire clamping group 4 have relatively large diameters. This structural design facilitates the limitation of cables 9 with different diameters.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
