Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a lamp holder used when mounting a lamp on an IC substrate or the like.

[Outline of the device]

The present invention is provided with a leg portion for mounting the holder on the board side, and by pressing the leg portion, the elasticity of the holder is used to hold the lamp, and there is no floating when soldering on the board. The lamp holder is designed so that the lamp lead is not stressed by the lamp.

[Prior art]

As a lamp holder of this type, as shown in FIGS. 4 and 5, a disk-shaped holder main body c having a hole b into which a lamp lead a is inserted, or a mounting position of a lamp d is maintained to some extent. It is known that a container-shaped holder main body c ′ is used. In this type of lamp holder, the board e
On the other hand, as shown in FIG. 6 and FIG. 7, it is possible to regulate the rising and the inclination only by bending the lamp lead a.

[Problems to be solved by the device]

Therefore, the soldering of the lamp leads to the board must be done manually. In addition, after soldering, the stress applied to the lamp is applied to the lamp lead as it is, which causes the destruction of the lamp. The present invention has been made based on the above circumstances, and if the lamp holder is held on the substrate, the lamp can be held securely,
An object of the present invention is to provide a lamp holder configured so that there is no rise and tilt when soldering on a substrate and the stress of the lamp is not applied to the lamp lead.

[Means for Solving the Problems]

Therefore, in the present invention, the lamp holding body is integrally formed with the lamp holder main body, and is integrally formed with the lamp holder main body and the lamp holding portion that surrounds and substantially holds the lamp and is inserted into the hole of the substrate. A plurality of legs for fixing the lamp clamped to the substrate to the substrate by the lamp clamping part, and when the legs are pressed toward each other, the lamp clamping part is elastic in the spreading direction. It is characterized in that the lamp is elastically deformed in the closing direction by elastically deforming in the closing direction by deforming and releasing the pressure applied to the leg portion.

【Example】

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. The lamp holder 1 according to the present invention is a disc-shaped holder body.
Groove 1b is formed in the center of 1a and counterbore 1
c, 1c are formed, and lead holes 1d, 1d are provided to project therefrom, and semi-cylindrical lamp holding parts 2, 2 are integrally formed on the left and right of the groove 1b. The leg portions 3, 3 are integrally formed on the bottom of the holder main body 1a corresponding to the holding portions 2, 2. In addition, pressing portions 2a, 2a for pressing the rubber cap portion 4a of the lamp 4 are formed on the inner peripheral surface of the lamp holding portions 2, 2. In such a structure of the lamp holder 1, when the leg portions 3, 3 are pinched by hand and pressure is applied in the arrow direction as shown in FIG.
The holder body 1a can be elastically deformed at the boundary, and the lamp holding portions 2 and 2 are opened. In this state, insert the lamp leads 4b, 4b into the lead holes 1d, 1d, place the lamp 4 on the holder body 1a, and remove the force applied to the legs 3, 3 as shown in Fig. 3. The space between the holding portions 2, 2 becomes narrower to hold the rubber cap portion 4a of the lamp 4. In this state, the leg portions 3 and 3 are fitted into the leg insertion holes 5a that have been drilled in the substrate 5 in advance. At the same time, the lamp leads 4b, 4b are inserted into the insertion holes 5b of the substrate 5. Then, the lamp leads 4b, 4b are connected to the lead ends of the substrate 5 by an automatic soldering operation such as a dip method. Therefore, when the lamp 4 is mounted on the holder body 1a, a pressure is applied between the lamp holding portions 2 and 2. Therefore, when the holder body 1a is held on the board 5 by the legs 3 and 3, the soldering work is performed. The lamp 4 does not float or tilt while operating. Therefore, for soldering, a dip-type automatic soldering work can be performed. In addition, even if stress is applied to the lamp 4 after soldering,
Since the lamp holder 1 supports this, the above stress is not applied to the lamp leads 4b, 4b,
Lamp destruction due to this is avoided. In the above-described embodiment, the lamp holding portions 2, 2 are formed in a semi-cylindrical shape, but in short, it is only necessary that the lamp 4 can be held elastically, and therefore the shape thereof may be appropriately changed in design. Further, in order to expand the space between the lamp holding portions 2 and 2, the leg portions 3 and 3 are pressed and elastically deformed at the location of the groove 1b of the lamp body 1a. Of course, the function may be achieved.

[Effect of device]

The present invention has been described in detail above, and since the lamp is securely held by the holder, the lamp is held more firmly when the lamp holder is mounted on the substrate with its legs. It is possible to obtain an effect that the soldering work of the lamp lead can be automated without rising or tilting, and a practical effect that stress applied to the lamp does not reach the lamp lead.
