Abstract

PURPOSE:To enable a lamp socket serving as a common part to be used with different plate thicknesses of a fitting main body by providing a mounting spring to the lamp socket and to achieve cost reduction and to facilitate installation by reducing the number of the sides of a molding die. CONSTITUTION:A lamp socket 2 serving as a common part is provided with a mounting spring 8 to eliminate the need for plural kinds of locking springs as to variations in the plate thickness and configuration of a fitting main body 1 and to facilitate standardization, and also, the socket 2 can be installed by one process. In addition, the socket 2 can be installed even if the plate thickness of the main body 1 varies. A terminal 13, provided along a direction 11 perpendicular to the first and second directions 9, 10 of installation which are perpendicular to the axis of a mounting hole 3, keeps the spring 8 from being readily deformed elastically by an external force applied to wire during connection of the wire, and the socket 2 is therefore not readily disconnected, so the mounting strength of the socket 2 is secured and the play of the socket 2 is reduced. Also, since the direction 9 is at 90 degrees to the direction 11 of connection of the wire and the directions 10, 11 are at 45 degrees to each other, a rectangular area formed when the socket 2 is axially projected is small, effective use of space is thus made possible, and installation operability is good.

However, in the first conventional example, since the fixture spring 50 is provided on the fixture body 50 side, when the lamp socket 54 is attached, the spring receiving portion 55 of the lamp socket 54 is retained by the lock spring 53. There is a drawback that the workability is poor because it is a two-operation operation of pressing the lamp socket and sliding the recess of the lamp socket to the edge of the mounting hole 51 to lock the lamp socket.

In the structure in which the locking spring 53 is fitted and fixed in the gap provided in the instrument body 50, when the instrument body 50 has different plate thicknesses, a plurality of plate thicknesses are used depending on the plate thickness. It is necessary to prepare the stop spring 53, and moreover, it is troublesome to mount it. In the second conventional example, since the lamp socket 54 is attached to the main body of the fixture with a screw, the number of parts increases and the assembly takes time. In addition, in such a structure, when the lamp spring can be locked to the main body of the fixture by the locking spring, the locking spring is located right below the wire connection part of the terminal, so the force at the time of inserting / removing the wire There is a risk that the lamp socket will come off. If a screw mounting part is provided directly below the wire connection part,
If you try to remove the screw with the wire inserted, the screwdriver will catch on the wire and the screwdriver bit will not hit the screw head, making it difficult to work.

In the third conventional example, two operations, that is, the operation of rotating the lamp socket 54 and the operation of reversing the spring 60 are required, and the workability is poor. The fourth conventional example shown in FIG. 10 has poor workability for screw mounting, and the fourth example shown in FIG. 11 has a possibility that the lamp socket may come off due to the force associated with the insertion and removal of the electric wire. The fifth conventional example has the same drawbacks as the fourth conventional example.

In the sixth conventional example, the structures of the instrument body and the lamp socket 54 are complicated. In the seventh conventional example, the structure of the instrument body 50 becomes complicated, and it is difficult to deal with repairing and screw mounting, especially when mounting strength of the lamp socket is required. Therefore, an object of the present invention is to easily attach / detach the lamp socket, and
It is an object of the present invention to provide a mounting structure for a lamp socket that can be made into various types and that has a simple structure.

In addition, two types of mounting can be selected, one is mounting by the locking spring 8 and the other is mounting by screws. When a large external force is applied, the lamp socket 2 can be firmly mounted by mounting by screws.

Furthermore, the first mounting direction 9 and the wire connecting direction 11 of the terminal 13 form about 90 degrees, and the second mounting direction 10
Since the wire connection direction 11 of the terminal 13 and the terminal 13 is about 45 degrees, the rectangular area when the lamp socket 2 is projected in the axial direction can be reduced, so that the space can be effectively utilized and the screw can be mounted. Sometimes it is easy to install the screwdriver bit into the screw head, so installation workability is good.

The stepped portion 34 having a predetermined height is provided on the bottom of the above, and the inner side surface is tapered so that the distance between the inner side surfaces of the locking recesses 6 becomes narrower toward the inner side. Reference numeral 35 is a lamp.

By providing the stepped portion 34 in the instrument body 1, a thickness corresponding to the inner width of the inner side surface composed of the lower surface and the upper surface of the locking recess 6 can be made. For example, the plate thickness t of the instrument body 1 = In 0.5 to 1.2, the inner width 1.
In the case of 2, when the plate thickness t = 0.5, the difference between the plate thickness and the inner width can be absorbed by knocking out the step portion 34 having a height of 0.7. Therefore, rattling can be surely prevented, and can be realized by simple squeezing, so that the fixture body 1 and the lamp socket mounting portion can be configured as one component, and therefore, the fixing strength of the lamp socket can be improved and the lamp socket can be improved. Installation of 2 is stable.

Further, if the inner side surface of the locking recess 6 is formed in a tapered shape, it is easy to engage with each other, the difference in thickness can be dealt with, and rattling can be surely prevented.
