Therefore, even if the operator inserts the bulb 40 with excessive force, the stopper 36 is regulated to the degree of insertion of the bulb 40.

When the hook protrusion 43 is located at a portion corresponding to the inlet of the seating portion 39c, the operator gives a rotational force in a counterclockwise direction with reference to FIG. 4B, and the hook protrusion 43 is attached to the seating portion 39c. Insert it. Since the width H of the portion forming the boundary between the connecting portion 39b and the seating portion 39c is smaller than the width J of the hooking protrusion 43, the hooking protrusion 43 is press-fitted to seat the seating portion 43. It is settled in the part 39c.

As shown in FIG. 4C, when the hook protrusion 43 is press-fitted into the inlet of the seating portion 39c, the bulb 40 is provided by the elastic force provided in the direction of the bulb 40 by the elastic terminal 37. Is fixed to the seating portion 39c, and thus the bulb 40 is fixed to the socket 35.

In this case, the length S of the seating portion 39c is formed longer than the width J of the hooking protrusion 43, and the portion forming the boundary between the seating portion 39c and the connecting portion 39b. Since the width H is formed to be smaller than the width J of the hook protrusion 43, the hook protrusion 43 does not move away from the seating portion 39c even when external force or vibration is applied to the bulb 40. This prevents the bulb 40 from being pulled out of the socket 35 arbitrarily.

The process of separating the bulb 40 from the socket 35 is performed in the reverse order of the above-described insertion process. In other words, the operator gives the force to overcome the elastic force of the elastic terminal 37 to position the hook projection 43 in the portion corresponding to the inlet of the seating portion (39c). At this time, the operator applies the bulb 40 to the connecting portion 39b by giving a rotational force in a clockwise direction with reference to FIG. 4C. After the hook protrusion 43 enters the connection portion 39b, the worker pulls the bulb 40 upward.

In order to be seated on the seating portion 139c, the hook protrusion 43 must be crossed over the hooking jaw 139 '. At this time, since the locking jaw 139 'may be elastically deformed due to the characteristics of the material, the hook protrusion 43 is pressed into the seating portion 139c while overcoming the elastic force of the locking jaw 139'. Since the hook protrusion 43 is press-fitted to the seating portion 139c and fixed, the bulb 40 may be prevented from being detached from the socket 35 by external force or vibration.

According to the embodiment illustrated in FIG. 5B, the hanger slot 239 includes a guide part 239a, a connection part 239b, and a seating part 239c.

The guide part 239a serves to guide the bulb 40 to be inserted at the correct position when the bulb 40 is inserted into the socket 35.

A connection portion 239b is formed to extend from the guide portion 239a in a substantially U shape, and is connected to the connection portion 239b to extend in a direction orthogonal to the guide portion 239a so that the seating portion 239c is formed. Is formed. In the present embodiment, the seating portion 239c is formed to the left side based on FIG. 5B but may be formed to the right side. The seating portion 239c is a portion on which the hook protrusion 43 is seated. The length S 'of the seating portion 239c is longer than the width J of the hook protrusion 43, and the width H of the portion forming the boundary between the connection portion 239b and the seating portion 239c. ) Is preferably formed smaller than the width (J) of the hook projection (43). This is to prevent the hook protrusion 43 from being detached from the seating portion 239c arbitrarily by external force or vibration after being seated on the seating portion 239c.

Looking at the process of coupling the bulb to the bulb holder according to this embodiment, first, the bulb 40 is inserted into the socket 35. In this case, the hook protrusion 43 is guided through the guide part 239a and the connection part 239b and positioned at the inlet of the seating part 239c. The width H of the portion forming the boundary between the seating portion 239c and the connection portion 239b is smaller than the width J of the hooking protrusion 43. Since the elastic deformation is possible due to the characteristics of the material forming the socket 35, the worker overcomes the elastic force and presses the hook protrusion 43 into the seating portion 239c. Since the hooking protrusion 43 is press-fitted into the seating portion 239c, the hooking protrusion 43 is not detached from the seating portion 239c arbitrarily so that the bulb 40 is fixed to the socket 35. .
