Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a door and window, and more particularly to a wire passing device between the sash and the frame of a door and window. Background Art

[0002] With the development of construction technology, more and more electronic products are installed in doors and windows, such as existing electronic door locks, etc. Most of these electronic products require power supply. The simplest method is to use an off-line power supply, such as a rechargeable battery, etc. However, the energy of such a power supply is limited, which is not conducive to long-term use and needs to be replaced regularly. Another method is to use an active power supply. However, due to the opening and closing of the door or window, the wires are very likely to be broken, which not only causes the electronic products to be unable to be used, but also has a risk of electric shock. The existing wire passing devices on the market are only a protective sleeve, which only plays a role in protecting the cable and slowing down the breakage of the cable. When maintenance is required, the cable cannot be quickly disconnected, which brings trouble to the installation of doors and windows. Content of the Utility Model

[0003] To solve the above technical problems, the purpose of the utility model is to provide a wire passing device for doors and windows. The socket and the plug are inserted into each other and fastened to the fixing plate by screws. The wire at the tail of the plug passes through the inside of the protective spring tube and is connected to the terminal block circuit board. The protective spring tube is fastened to the sash side groove body by a spring fixing piece and screws. The terminal block circuit board is embedded in the sash side groove body through a circuit board base. The quick-break fuse is installed in the fuse base on the terminal block circuit board.

[0004] The socket and the fixing plate are installed and fixed on the frame side.

[0005] There are 2 terminal block circuit boards, both of which are arranged on the circuit board base, and a fuse base is arranged between the terminal block circuit boards.

[0006] The wiring surface of the terminal block circuit board is an inclined surface.

[0007] A waterproof sealing ring is installed on the plug.

[0008] The advantages of the utility model are as follows: A stable and quickly connectable and disconnectable circuit connection structure is formed by the plug, the socket, the fixing plate, the protective spring tube, the sash side groove body, etc., which is convenient for the quick installation or disassembly of the door and window sash. At the same time, the setting of the double terminal block circuit boards and the fuse base can effectively prevent the overloading and burning of the circuit products on the door and window sash and prolong their service life. Compared with the ordinary straight surface, the inclined wiring surface is convenient for construction. Description of the Drawings

[0009] Figure 1 It is a structural schematic diagram of the utility model;

[0010] Figure 2It is a schematic structural diagram of a terminal block circuit board. Specific embodiments

[0011] The present invention will be specifically described below with reference to the accompanying drawings. As shown in the figure, the socket 1 and the plug 2 are inserted into each other and fastened to the fixing plate 3 by screws; the wire at the tail of the plug 2 passes through the inside of the protective spring tube 4 and is connected to the terminal block circuit board 7. The protective spring tube 4 is fastened to the fan-side groove body 5 by a spring fixing member 9 and screws. The terminal block circuit board 7 is embedded in the fan-side groove body 5 through a circuit board base 6. The quick-fusing fuse 8 is installed inside the fuse base on the terminal block circuit board 7; the spring fixing member can be a combination of a clamp and screws;

[0012] The socket 1 and the fixing plate 3 are installed and fixed on the frame side;

[0013] To prevent the overloading and burning of circuit products on the door and window fan and extend their service life, there are 2 terminal block circuit boards 7, both of which are arranged on the circuit board base 6, and a fuse base is arranged between the terminal block circuit boards 7.

[0014] To facilitate installation and construction, the wiring surface of the terminal block circuit board 7 is an inclined surface.

[0015] For waterproofing, a waterproof sealing ring 10 is installed on the plug 2.
