[0002] Currently, there is a threaded wiring connector, which structurally includes two parts, namely a sleeve and a nut. The sleeve and the nut are threadedly connected and communicated. The nut includes a screw portion and a head connected in sequence along the axial direction. The head is provided with a port. The cable passes through the sleeve, the screw portion, the head and enters the junction box from the port in sequence. The purpose of the threaded connection between the sleeve and the nut is to be compatible with different connection holes provided on the junction box. The principle of compatibility is that the sleeve is threadedly connected to the screw portion of the nut, and a clamping interval with a variable spacing is formed between the front end face of the sleeve and the rear side face of the head of the nut, and the compatibility purpose is achieved through the variable spacing.

[0003] However, although the current threaded wiring joints have good compatibility, they do not have relevant structures to prevent debris, mortar (which will become clogged when the mortar solidifies), etc. from entering the threaded wiring joints through the ports. At the decoration site, due to the existence of many uncertain factors, and the junction box is an open design before the panel is installed, debris, mortar, etc. often enter the threaded wiring joints through one side of the junction box, which is not conducive to smooth wiring and may even wear the cables. Therefore, how to solve this technical problem simply and at a low cost while making it convenient for workers to operate during construction is worthy of study. Utility Model Content

A clamping gap with a variable spacing is formed between the front end face of the sleeve and the rear side face of the head of the nut. The clamping gap is used to connect the connection hole provided on the junction box. The front end of the head is provided with an end cover for covering the port.

[0006] As an improvement, the circumference of the port and the end cover are seamlessly integrated to form a blind hole; or the circumference of the port is provided with an annular end face, and a gap is provided between the annular end face and the end cover, and the gap is used to reduce the connection between the annular end face and the end cover to facilitate opening the end cover, or a connection gap is provided, and the connection gap is provided for a tool to be inserted to open the end cover to expose the port.

[0007] As an improvement, a connecting column is provided between the annular end surface and the end cover, and the connecting column is located on the outer periphery of the end cover.

[0008] As an improvement, a plurality of connecting columns are provided, and connecting gaps are provided between adjacent connecting columns.

[0009] As an improvement, the outer circumference of the sleeve is provided with a first polygonal structure for applying force.

[0010] As an improvement, the outer periphery of the head is provided with a second polygonal structure for applying force.

[0011] As an improvement, the circumferential portion of the rear side surface of the end cover is connected to the front end surface of the head, and a step is formed between the end cover and the front end surface of the head, and the step is used for a tool to remove the end cover.

The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] The utility model is further described in detail below:

[0023] like Figure 1 As shown, a threaded wire connector is disclosed, including a sleeve 1 and a nut 2. The nut 2 includes a screw portion 3 and a head 4 arranged in sequence along the axial direction. The head 4 is provided with a port 5. The sleeve 1 is threadedly connected to the screw portion 3 of the nut 2. A clamping gap with a variable spacing is formed between the front end face 6 of the sleeve 1 and the rear side face 7 of the head 4 of the nut 2. The clamping gap is used to connect to the connection hole provided on the junction box 14. The front end of the head 4 is provided with an end cover 8 for covering the port 5.

[0024] like Figure 5 、 6 As shown, the junction box 14 is provided with three types of connection holes, each connected to a threaded wire connector. Due to the different axial lengths of the connection holes provided on the junction box 14, the clamping intervals are different, which makes the threaded wire connectors have good compatibility. The wire tube 13 is connected to the junction box 14 by being connected to the sleeve 1 at one end.

[0025] In order to further keep the entire threading pipeline unobstructed, the threading tube 13 is also sleeved with a protective cap 16 at the other end.

[0026] The connection state between the end cover 8 and the port 5 can be different structures. For example, the circumference of the port 5 and the end cover 8 are seamlessly integrated so that the nut 2 forms a blind hole.

[0027] For another example, an annular end surface 9 is provided around the port 5 , and a gap is provided between the annular end surface 9 and the end cover 8 . The gap is used to reduce the connection between the annular end surface 9 and the end cover 8 to facilitate opening the end cover 8 .

[0028] For example, Figure 1As shown, a connection gap 10 is provided between the annular end surface 9 and the end cover 8 , and the connection gap 10 is for a tool to be inserted to open the end cover 8 to expose the port 5 .

[0029] For example, Figure 7 As shown, the circumferential portion of the rear end surface of the end cap 8 is connected to the front side surface 12 of the head 4, and a step (15) is formed between the end cap 8 and the front side surface 12 of the head 4. The step (15) is used for a tool to remove the end cap 8. The tool, such as a spatula, scrapes off the step 15 to remove the end cap 8. The above structure is very suitable for the design structure of the above-mentioned blind hole and the design structure of the above-mentioned gap, thereby improving the construction convenience.

[0030] like Figure 1 、 3 As shown, the annular end surface 9 is the inner peripheral portion of the front side surface 12 .

[0031] In some embodiments, as Figure 1 As shown, a connecting column 11 is provided between the annular end face 9 and the end cover 8, and the connecting column 11 is located at the outer periphery of the end cover 8. In this way, not only the end cover 8 is connected to the annular end face 9, but also the end cover 8 is easy to open.

[0032] Furthermore, a plurality of connecting columns 11 are provided, and connecting gaps 10 are provided between adjacent connecting columns 11 .

[0033] In some embodiments, as Figure 1 As shown, the outer circumference of the sleeve 1 is provided with a first polygonal structure for applying force. The first polygonal structure is, for example, a hexagonal structure, so as to be suitable for a hexagonal wrench.

[0034] The outer periphery of the head 4 is provided with a second polygonal structure for applying force. The second polygonal structure is, for example, a hexagonal structure, so as to be suitable for a hexagonal wrench.
