Hereinafter, an embodiment of an elastic terminal module assembly method for assembling the elastic terminal module 100 of the present invention described above will be described.

Figure 8 is a diagram illustrating the method of assembling the elastic terminal module 100 in step-by-step order. Figure 8 (a) is a diagram showing the state before the terminal fixing part 150 is folded. (b) is a view showing the terminal fixing part 150 in a folded state, and Figure 8 (c) is a drawing showing the elastic contact terminal 110 inserted into the terminal fixing part 150 in the folded state. am.

The method of assembling the elastic terminal module 100 according to this embodiment may include a bending step, a joining step, and a fixing step.

As shown in (b) of FIG. 8, the bending step involves bending the bending portion 154 so that the second piece 152 of the terminal fixing portion 150 overlaps the upper surface of the first piece 151. It can be folded to the center.

In the coupling step, as shown in (c) of FIG. 8, the elastic part 111 of the elastic contact terminal 110 is inserted between the first piece 151 and the second piece 152. This may be a step of pushing the contact terminal 110 between the first piece 151 and the second piece 152 on the opposite side of the side where the bending portion 154 is formed.

In the coupling step, one or a plurality of elastic contact terminals 110 may be coupled between the first piece 151 and the second piece 152.

In the fixing step, after the required number of elastic contact terminals 110 are combined, opposite sides of the first piece 151 and the second piece 152 on which the bending portion 154 is formed are joined. This is the step of fixing the first piece 151 and the second piece 152.

In the fixing step, opposite sides of the first piece 151 and the second piece 152 on which the bending portion 154 is formed are joined, so that the elastic contact terminal 110 is connected to the first piece 151 and the second piece 152. Separation between the pieces 152 in the first and second directions is prevented, and coupling and fixation can be completed.

Since the moving direction when the elastic contact terminal 110 is inserted into the terminal fixing part 150 and the direction in which the elastic contact terminal 110 receives pressure when making electrical contact are orthogonal to each other, the elastic contact occurs. Even if continuous pressure for electrical contact is applied to the terminal 110, separation of the elastic contact terminal 110 can be prevented.

In addition, since the elastic contact terminal 110 is always in close contact with the contact terminal 210 of the ultraviolet lamp module 200 due to the elasticity, the occurrence of poor contact phenomenon can be prevented or minimized.

At this time, a seating chamber in which the elastic terminal module 100 is located is formed in the base 300, and fastening holes for fastening the bracket 400 may be formed at a plurality of places on the edge.

The ultraviolet lamp module 200 may be formed in the shape of a rectangular parallelepiped with rounded edges as a whole, and may be formed of a transparent material such as glass or quartz to emit ultraviolet rays to the outside. Additionally, wires 210 for electrical contact with the elastic terminal module 100 may be printed and formed on the surface of the ultraviolet lamp module 200.

In addition, the bracket 400 may be formed in a '∩' shape with an open lower side in order to fix the ultraviolet lamp module 200 to the base 300. The bracket 400 fixes the ultraviolet lamp module 200 to the base 300 and presses the ultraviolet lamp module 200 toward the elastic terminal module 100 mounted on the base 300 to irradiate the ultraviolet lamp. The module 200 and the elastic terminal module 100 can be fixed so as to be in electrical contact.

Therefore, a component for applying power or a signal to the ultraviolet lamp module 200 is provided as the elastic terminal module 100, and soldering is performed in the electrical contact structure between the elastic terminal module 100 and the ultraviolet lamp module 200. Since there is no soldering that is vaporized and lost by ultraviolet rays emitted from the ultraviolet lamp module 200, durability can be improved. Although embodiments of the present invention have been described, the spirit of the present invention is not limited to the embodiments presented herein. It is not limited by example, and a person skilled in the art who understands the spirit of the present invention will be able to easily suggest other embodiments by adding, changing, deleting, or adding components, etc., within the scope of the same spirit. It will be said to fall within the scope of the invention.
