Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, and in particular relates to a photovoltaic cable female connection plug structure which is easy to plug and unplug. Background Art

[0002] At present, after the male and female connectors of the photovoltaic junction box cable are plugged in, it is difficult to unplug and separate the male and female connectors, and special tools are required to unplug them. It is very inconvenient for daily plugging and unplugging of the male and female connectors of photovoltaic modules or for module maintenance without special tools, and there are certain limitations;

[0003] like Figure 4 In the conventional female connecting plug shown, the edge of the female connecting plug body is fixedly connected to the edge of the kit, and the male head snap-in fixing groove is enclosed therein. After the male connecting plug is inserted, the snap-in block is snapped into the male head snap-in fixing groove, and it is inconvenient to separate the snap-in block from the male head snap-in fixing groove. If a special extraction tool is not carried, it is inconvenient to separate the male and female connecting plugs, and the use is limited. Utility Model Content

[0004] The purpose of the utility model is to provide a photovoltaic cable female connection plug structure that is easy to plug and unplug, so as to solve the problems in the prior art. The specific technical solution is as follows:

[0005] A photovoltaic cable female connector plug structure which is easy to plug and unplug comprises a female connector body which is fixedly connected to a kit via a connector, and extrusion structures are provided on both sides of the kit.

[0006] Furthermore, the extrusion structure includes a support arm and an extrusion block, one end of the support arm is fixed to one end of the extrusion block, and the other end of the support arm is fixed to the sleeve.

[0007] Furthermore, a male clamping fixing groove is provided at the connection between the support arm and the kit.

[0008] Furthermore, the support arm adopts a thin-wall design with a thickness between 0.5 and 1 mm, a length between 1 and 2 mm, and is elastic.

[0009] Furthermore, the extrusion block adopts a thick-wall design with a thickness between 2 and 3 mm.

[0010] Furthermore, a sliding arm 1 is provided on the inner side of the extrusion block, and the sliding arm 1 adopts an arc design.

[0011] Furthermore, a deformation opening is provided between the extrusion block and the female connector body.

[0012] Furthermore, an elastic rubber gasket is provided at the end of the kit.

[0013] Furthermore, the female connector body is connected to the male connector body in a sliding fit, and the connector and the kit are both connected to the male connector body in a sliding fit.

[0014] Furthermore, the male connector body is provided with clamping blocks on both sides, the clamping blocks are elastic, the clamping blocks are clamped in the male head clamping fixing groove, and the clamping blocks are provided with sliding arms 2, which are fitted with sliding arms 1.

[0015] The advantages of the utility model are:

[0016] 1. Press the two extrusion structures, and the two extrusion structures move toward each other to squeeze and separate the male connection plug stuck in the female connection plug, so as to facilitate the separation and removal of the male and female connection plugs. In the case of not carrying a special extraction tool, the male and female plugs can be separated quickly and conveniently, which is more convenient, quick and has no limitations;

[0017] 2. The main function of the support arm is to support the extrusion block. At the same time, the support arm adopts a thin-wall design. The thickness of the support arm is relatively thin compared to the extrusion block. In addition to ensuring its own strength, it also has a certain elastic function. When the male connection plug is inserted into the female connection plug, the extrusion block moves outward, driving the support arm to undergo a certain elastic deformation outward. After the clamping block on the male connection plug is clamped into the male clamping fixing groove, the support arm returns to its original state without affecting the reliability of the clamping fixation of the male and female heads.

[0018] 3. The wall surface of the sliding arm 1 adopts an arc design. Its main function is that when the male connecting plug is inserted, the sliding arm 1 slides with the sliding arm 2 arranged on the clamping block, which plays a good natural transition role and makes it more convenient for the male connecting plug to be quickly inserted and removed. The size of the arc can be set according to actual conditions. BRIEF DESCRIPTION OF THE DRAWINGS

The size of the arc can be set according to actual conditions.

[0047] Embodiment 6

[0048] like Figure 1-3 As shown, a deformation opening 5 is provided between the extrusion block 4 and the female connector body 6;

[0049] The working principle of the above technical solution: The design of the deformation opening 5 is mainly to provide elastic space for the extrusion block 4 to prevent the extrusion block 4 from scratching against the edge of the female connector body 6 when moving, thereby affecting the movement of the extrusion block 4. The size of the opening is usually 0.5 to 1 mm.

[0050] Embodiment 7

[0051] like Figure 1-3 As shown, an elastic rubber gasket is provided at the end of the kit 8;

[0052] The working principle of the above technical solution is: after the male connecting plug is inserted into the female connecting plug, the clamping block 10 is clamped into the male head clamping fixing groove 1, and the male connecting part body 9 is pressed on the elastic rubber gasket at the end of the kit 8, causing the elastic rubber gasket to deform, further increasing the tightness of the male and female connecting plugs to prevent loosening.
