As shown in the drawings, in the terminal bracket of the embodiment of the present invention, the bracket body 10 forms the skeleton and the outer shape. The bracket body 10 is configured in a substantially ring shape, and has a through portion 12 passing through the center. The bracket body 10 may be made of a synthetic resin material through injection molding. The shape of the bracket body 10 is not necessarily the same as the shape shown in the drawings. However, the through portion 12 needs to be formed in a circular shape.

The bracket body 10 is mounted in a lamp housing (not shown), and the center of the through-hole 12 coincides with the center of the through-hole formed in the lamp housing. The lamp housing may be one in which one or more lamps are mounted. The lamp mounted on the penetrating portion 12 of the bracket body 10 is mounted on the terminal bracket while being mounted on the lamp holder 90 (see FIG. 6).

There is a locking lever 14 on one side of the inner surface of the bracket body 10 . The engaging lever 14 can be elastically deformed. In this embodiment, the locking lever 14 has a cantilever shape. However, the locking lever 14 does not necessarily have a cantilever shape, and may be any if elastic deformation is possible.

A hooking jaw 16 protrudes from the hooking lever 14. In this embodiment, the hooking jaw 16 is formed on the free end side of the hooking lever 14. A hooking jaw (not shown) of the lamp holder 90 is hung on the hooking jaw 16 . While the locking jaw 16 is hooked to the hooking jaw 16, the latching lever 14 with the hooking jaw 16 is elastically deformed to prevent damage to the hooking jaw 16 or the latching jaw, and the lamp holder 90 ) is relatively reduced in the force of attaching and detaching from the terminal bracket. The hooking jaw 16 has a curved surface in the direction in which the hooking jaw rides over, that is, in the direction of mounting movement and detaching movement of the lamp holder 90. That is, there are curved surfaces on both the base side and the free end side of the locking lever 14 . This is to allow the lamp holder 90 to be mounted and detached when a certain amount of force is applied without a separate tool.

Since the hooking lever 14 extends along the inner surface of the bracket body 10, it can have a predetermined radius of curvature when viewed from a plan view, and the hooking jaw 16 is attached to the penetrating part 12 to hold the lamp holder 90. ) protrudes in one of the directions of insertion and separation.

Terminal spaces 18 are formed in at least two places in the bracket body 10 . In the terminal space 18, a part of the terminal 30 to be described below is located. The terminal space 18 is opened to the rear surface (refer to FIG. 2) and the inner surface of the bracket body 10. A portion of the terminal space 18 that is open toward the penetrating portion 12 is called a contact window 20 . Through the contact window 20, the contact piece 37 of the terminal 30, which will be described below, is exposed and comes into contact with the holder terminal 92 of the lamp holder 90.

A fixed channel 22 is formed on the inner surface of the terminal space 18. In this embodiment, two fixed channels 22 are formed side by side. Two fixed channels 22 are formed side by side and extend from the outside of the terminal space 18 toward the inside. In the fixed channel 22, a fixed end 39 of a terminal 30 to be described below is positioned and moved. The terminal extension part 24 is formed so that the terminal space 18 is exposed to the outer surface of the bracket body 10. The body portion 32 of the terminal 30, which will be described below, passes through the terminal extension portion 24.

The terminal 30, a part of which is seated in the terminal space 18, is made of a conductive metal material. The terminal 30 allows external power to be transmitted to the lamp. The terminal 30 has a body portion 32 and an external coupling portion 34 extending from one side of the body portion 32 . The external coupling portion 34 is a portion connected to the power supply side, and for example, an electric wire may be coupled thereto.

The external coupling part 34 is configured to extend in a direction orthogonal to the extension direction of the body part 32 and may be positioned to extend along the outer surface of the bracket body 10 . On the opposite side of the body part 32, that is, on the opposite side of the side where the external coupling part 34 is located, there is a contact part 36 electrically connected to the holder terminal of the lamp holder 90. The contact part 36 has a contact piece 37 connected to the body part 32 . The contact piece 37 is exposed to the through portion 12 through the contact window 20 . At both ends of the contact piece 37, a portion connected to an elastic providing portion 38 to be described below is a curved surface. This is to ensure that the holder terminal 92 of the lamp holder 90 or the contact protrusion 94 formed on the holder terminal 92 is smoothly guided to the surface of the contact piece 37.

Connected to both ends of the contact piece 37, elastic providing parts 38 are formed, respectively. The elastic providing part 38 has a substantially 'U' shape in cross section. Each of the elastic providing parts 38 has a deformation space 38', and the elastic providing part 38 is elastically deformed so that the deformation space 38' becomes narrow. Extending from the elastic providing part 38, fixing ends 39 are respectively provided. The fixing end 39 is located on the fixing channel 22 and supports the elastic providing part 38 so that elastic deformation occurs in the elastic providing part 38 when the holder terminal is in close contact with the contact piece 37. play a role

Hereinafter, the assembly and use of the terminal bracket according to the present invention having the above configuration will be described in detail.

In the present invention, the bracket body 10 is made by injection molding, and the terminal 30 is made by press working a single metal plate. The terminal 30 is assembled such that the contact portion 36 is positioned within the terminal space 18 of the bracket body 10 . At this time, the fixed end 39 is inserted into a pair of fixed channels 22 formed in the terminal space 18 and positioned.

The external coupling part 34 of the terminal 30 is connected to the body part 32 located on the terminal extension part 24 and is located on the outer surface of the bracket body 10. An electric wire connected to the power supply side is coupled to the external coupling part 34, for example. The contact piece 37 of the terminal 30 is exposed to the penetrating portion 12 through the contact window 20, and the surface of the contact piece 37 is exposed to the penetrating portion 12 of the bracket body 10. ) It is good that it is in the same position as the inner surface or slightly protrudes.

In this way, in the terminal bracket after assembly of the terminal 30 is completed, the center of the through-hole 12 and the through-hole formed in the lamp housing are installed on the inner surface of the lamp housing. In the state where the terminal bracket is installed in the lamp housing, the lamp holder 90 penetrates the through hole and the through portion 12 to allow the lamp to enter the lamp housing, and the clamping jaw (shown) in the lamp holder 90 not) moves along the hooking lever 14 of the bracket body 10 and climbs over the hooking shoulder 16. In the process of the hooking jaw riding over the hooking jaw 16, the hooking lever 14 is elastically deformed. When the locking jaw completely rides over the hooking jaw 16, the elastic deformation of the locking lever 14 is restored, and the locking jaw is hooked on the hooking jaw 16 to be fastened.

The holder terminal 92 of the lamp holder 90 is in contact with the contact piece 37 of the terminal 30 at the same time that the hook is hooked on the hook 16. The lamp holder 90 is rotated about the center of the through portion 12 while being inserted into the through portion 12, and the hanging jaw 16 is hooked to the hanging jaw 16. By this rotation, the holder terminal As 92 moves, the holder terminal 92 contacts the contact piece 37 as shown in FIG. 6 . The holder terminal 92 may directly contact the contact piece 37 or a contact protrusion 94 protruding from the holder terminal 92 may contact the contact piece 37 .

The contact of the holder terminal 92 with the contact piece 37 is made at the position of the contact window 20, and when it moves around the contact window 20 and enters the contact window 20, the contact The holder terminal 92 moves to the surface of the contact piece 37 along the curved surface of one end of the piece 37.

As the holder terminal 92 comes into close contact with the contact piece 37, elastic deformation occurs in the elastic providing part 38. Due to the elastic deformation, the deformation space 38' of the elastic providing part 38 is narrowed, which means that the fixed end 39 at one end of the elastic providing part 38 is connected to the fixed channel 22. because it is fixed in For reference, when the elastic deformation of the elastic providing part 38 is made, the body part 32 moves slightly to the outside through the terminal extension part 24 .

In this way, when the holder terminal 92 contacts the contact piece 37, power transmitted through the wire coupled to the external coupling part 34 can be transmitted to the lamp of the lamp holder 90.

Meanwhile, when the lamp holder 90 needs to be separated from the terminal bracket, the lamp holder 90 is rotated in a direction opposite to the rotation direction of the lamp holder 90 when mounted. In this case, the hooking jaw of the lamp holder 90 rides over the hooking jaw 16 and the hooking is released. At this time, the reason why the hooking jaw 16 rides over is that the hooking jaw 16 has curved surfaces on both sides of the latching lever 14 in the longitudinal direction. Elastic deformation occurs in the locking lever 14 while the locking step rides over the locking jaw 16, and then is restored.

When the hook is released from the hook 16, the lamp holder 90 is removed from the penetrating portion 12 and the lamp is separated from the lamp holder 90 to perform maintenance work.
