DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0016] Example 1

[0017] like Figures 1 to 3 As shown, the utility model provides a PTC heater base that is easy to install, and specifically includes a base 1, a cubic boss 2, a movable clamping plate 4, a conductive sheet 5, a conductive wire 6, a first screw 7 and a spring 8;

[0018] Among them, cube-shaped bosses 2 of the same size are evenly distributed at the rear end of the base 1 for stably placing the PTC heater;

[0019] Among them, a chute 3 is provided at the tangent point between the inner side of the rear end of the base 1 and the cube-shaped boss 2. A movable clamping plate 4 is slidably arranged in the chute 3. The protruding parts of the movable clamping plate 4 correspond to the cube-shaped bosses 2 in a staggered manner. Conductive sheets 5 are provided on the upper right side of the protruding parts of the movable clamping plate 4, which are bent at a certain angle near the protruding parts of the movable clamping plate 4 and the cuboid bosses for contacting and connecting with the electrode wires of the heater;

[0020] Among them, a conductive wire 6 is provided at the rear end of the conductive sheet 5. The first screw 7 is threadedly arranged on the left side of the base 1. The first screw 7 contacts the movable clamping plate 4. A spring 8 is provided between the end of the movable clamping plate 4 far from the first screw 7 and the base 1 for adjusting the moving distance of the movable clamping plate 4.

[0021] In the present utility model, a PTC heater base 1 that is convenient for installation is designed. The design of this base 1 aims to facilitate the wiring work of the staff. A device that can replace the wiring is designed. The principle is as follows: while the staff rotates the flat-head bolt clockwise, they observe the movement of the moving clamping plate 4. It can be observed that as the flat-head bolt rotates clockwise, the flat-head bolt presses against the moving clamping plate 4 and moves it into the sliding groove 3, and the spring 8 is compressed as the moving clamping plate 4 moves. It can be observed that some of the conductive sheets 5 located on the moving clamping plate 4 will first come into contact with the electrode sheets of the PTC heater. The conductive sheet 5 is a sheet-like object bent at a certain angle. The conductive sheet 5 has elasticity and conductivity. In order to adapt to the situation where the distance between the electrode sheets of the PTC heater may be different from the distance between the conductive sheets 5, the bending angle of the conductive sheet 5 is not very large, so that the conductive sheet 5 has a relatively large compression space. It can be observed that the conductive sheet 5 that first comes into contact with the electrode sheet of the PTC heater will be squeezed and still has enough compression space. It can also be observed that there are still electrode sheets of the PTC heater that are not in contact with the conductive sheet 5. Continue to rotate the flat-head bolt clockwise, and the moving clamping plate 4 continues to move deeper into the sliding groove 3 until all the electrode sheets are in full contact with the conductive sheet 5. Then the staff stops rotating the bolt, and the installation of the PTC heater is completed. The steps are simple and fast. Connecting the conductive sheet 5 to the wiring device omits a large number of wiring steps. In this way, contacting the electrode sheet with the conductive sheet 5 replaces the traditional one-by-one wiring method, greatly saving the time of the staff. At the same time, due to the mobility of the moving clamping plate 4 and the certain compression space of the conductive sheet 5, the base 1 can easily handle different models of PTC heaters with different electrode sheet thicknesses. When the bolt is rotated counterclockwise, it can be observed that the spring 8 pushes the moving clamping plate 4 to move and stretch. Although the conductive sheet 5 presses against the electrode sheet, it gradually unfolds. Continue to rotate the bolt counterclockwise, and it can be observed that some of the conductive sheets 5 begin to separate from the contact with the electrode sheet. It can be observed that these conductive sheets 5 return to their original shapes due to their own elasticity. Continue to rotate the bolt counterclockwise, and it can be observed that all the conductive sheets 5 are separated from the PTC heater. This is convenient for subsequent replacement when the PTC heater is damaged.

[0022] Embodiment 2

[0023] As Figures 1 to 4 shown, on the basis of Embodiment 1, it specifically further includes a fixing seat 9, a top cover 10, a second screw 11, and a transparent plate 12. On the upper part of the front side of the base 1, the fixing seats 9 are symmetrically arranged on the left and right. A top cover 10 is rotatably arranged between the two fixing seats 9. One end of the top cover 10 away from the fixing seat 9 is fixedly provided with a second screw 11 between it and the base 1. A whole transparent plate 12 is provided on the side of the top cover 10 close to the screw.

[0024] A top cover 10 is designed to be used in conjunction with the base 1. Before using the base 1, the staff puts the PTC heater electrode sheet into the gap between the protruding part of the movable clamping plate 4 and the three-dimensional boss. The PTC heater should be placed upright. Then, the staff flips the top cover 10, and the top cover 10 rotates and cooperates with the fixing seat 9. The top cover 10 is flipped to the surface of the base 1 to cover the PTC heater, and the elastic gasket 13 is located under the top cover 10, which will squeeze the PTC heater to fix it. Then, the top cover 10 is fixed with screws. This operation paves the way for subsequent operations and realizes the reliable fixation of the PTC heater. The wiring of the PTC heater can be effectively completed by observing through the transparent plate 12 above the top cover 10.

[0025] like Figure 4 As shown, based on the first embodiment, an elastic gasket 13 is further included. The elastic gaskets 13 are symmetrically arranged on the left and right sides of the bottom of the top cover 10 .

[0026] The elastic gasket 13 assists in fixing the PTC heater and prevents the PTC heater from being damaged by squeezing.

[0027] like Figure 5 As shown, on the basis of Example 1, it specifically includes a connecting block 14, a terminal 15, a copper circuit 16 for the live wire, a copper circuit 17 for the neutral wire and a protective cover 18. The rear end of the base 1 is provided with a connecting block 14 by a mortise and tenon joint. The terminal 15 is connected to the electric wire and fixedly arranged on the side of the connecting block 14 close to the base 1. The copper circuit is fixedly divided and arranged on the connecting block 14. The two types of copper circuit branches are staggered and connected to the terminal 15 and converge into their respective main circuits. The protective cover 18 is detachably arranged on the upper part of the connecting block 14 and has a through opening on the side close to the base 1.

[0028] When the staff uses the flat-head bolts to push the movable clamping plate 4, as the conductive sheets 5 fixed on the movable clamping plate 4 move with the movable clamping plate 4, the distance between the conductive sheet 5 and the terminal 15 will change, and the conductive wire 6 has a certain length to adapt to the change in the distance between the conductive sheet 5 and the terminal 15. If the staff connects the rated power live wire to the base 1 through the live wire interface and connects the neutral wire through the neutral wire interface, the branches of the neutral and live wire copper circuits are alternately connected to the terminal 15. Therefore, the properties of the terminal 15 and the conductive sheet 5 correspond to the arrangement of the PTC heater electrode sheets in the order of zero--live--zero, ensuring the correct connection method of the PTC heater using the device.

[0029] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
