Abstract
The utility model discloses a junction box with a wire clamping structure, which comprises a box body, wherein one end of the box body is provided with a cable, the other end of the box body is provided with the wire clamping structure, the wire clamping structure consists of a support and a cantilever, and the support and the cantilever are independent; the support is provided with a U-shaped groove, and at least one end of the support far away from the box body is provided with a U-shaped groove wall; the cantilever and the outer wall of the end part of the box body form a certain angle, and the top end of the cantilever is away from the groove wall of the support far away from the box body by a certain distance, so that the cantilever and the cable form interference fit. The utility model is suitable for a miniature terminal box can satisfy card line demand well.
Description
Technical Field
The utility model belongs to the technical field of solar cell, especially, relate to solar cell terminal box, more specifically, be the terminal box that has the card line structure.
Background
The junction box is used for connecting a bus bar on the solar cell and outputting current to the outside after rectifying, so that a cable is necessarily connected with the junction box. In most cases, the length of the cable is greater than what is actually needed, and the excess cable is randomly bent and distributed in the space around the junction box. The applicant has applied for a utility model named "solar junction box", with a patent number of 2011204863223, and the application has set an S-shaped wire clamp at the box body twice to engage with the cable, so as to fix the cable and prevent it from swinging freely. However, the scheme can only be suitable for a larger junction box and is not suitable for a small junction box, and meanwhile, the structure of the scheme does not have any elastic space, so that the requirement on the wire clamp material is high, the wire clamp material cannot be too soft or too hard, and the cost is increased invisibly.
Disclosure of Invention
The utility model aims at providing a less terminal box that has card line structure.
The utility model adopts the technical proposal that: terminal box with card line structure, including a box body, the one end of box body has the cable conductor, its characterized in that: the other end of the box body is provided with a wire clamping structure, the wire clamping structure consists of a support and a cantilever, and the support and the cantilever are mutually independent; the support is provided with a U-shaped groove, and at least one end of the support far away from the box body is provided with a U-shaped groove wall; the cantilever and the outer wall of the end part of the box body form a certain angle, and the top end of the cantilever is away from the groove wall of the support far away from the box body by a certain distance, so that the cantilever and the cable form interference fit.
Further, the support and the cantilever are each independently formed integrally with the case.
The cantilever can form a right angle with the outer wall of the end part of the box body and also can form an acute angle.
One of the support and the cantilever is integrally formed with the box body, and the other part is movably connected with the box body.
The support and the box body are integrally formed, a clamping seat is arranged on the outer wall of the box body, and the cantilever is clamped on the clamping seat.
The utility model arranges the cable and the wire clamping structure at the two ends of the box body in the length direction, so the box body is clean in the width direction and the arrangement and use of a plurality of box bodies are not influenced; the support and the cantilever are independent respectively, so that the structural elasticity is better ensured, and the requirement on the elasticity of materials is reduced; the cantilever and the box body form a certain angle, especially when the angle is a small acute angle, so that the angle can be changed to a certain degree, and the elasticity of the cantilever is increased. If the cantilever is movably connected with the box body, the requirement on manufacturing the die can be reduced.
It is visible, the utility model is suitable for a miniature terminal box can satisfy the card line demand well.

Detailed Description
See fig. 1, fig. 2. The embodiment comprises a cuboid box body 300, wherein one end of the box body is provided with a cable 400, and the other end of the box body is provided with a support 100 and a cantilever 200; the support 100 is connected with the box body through two support arms, a U-shaped groove is formed in the direction vertical to the length of the box body, and the end far away from the box body is a groove wall 101; the cantilever 200 is attached to the case by its bottom, projecting upward to form an acute angle with the case, and is not physically connected to the support. By the structure, the cantilever 200 can be extruded inwards and has elasticity, the distance between the top end 201 and the groove wall 101 is slightly smaller than the diameter of the cable, and interference fit can be formed; when the cable conductor is impressed the U type groove downwards, cantilever top 201 extrudees inwards slightly, can make the cable conductor through getting into U type groove, then top 201 resets when loosening, blocks the cable conductor in U type groove.
See fig. 3. This embodiment is substantially the same as embodiment 1 except that the cantilever arm 200 is extended downward to form an acute angle with the case, and is also pressed inward to fit the cable.
See fig. 4, fig. 5. This embodiment is basically the same as embodiments 1 and 2, except for the structure and mounting manner of the cantilever 200. In this embodiment, the cantilever 200 is a U-shaped component independent from the box, the outer wall of the box has an integrally formed socket 205, one side of the cantilever 200 extends into the socket 205 to be engaged therewith, so that the other side has a certain elasticity, and a gap between the top end 201 and the slot wall 101 is provided for the cable to be pressed into the socket 100 and to be in interference fit.
Claims (5)
