Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea relays straight tube lamps, small lamps, etc. to external connection members such as tab terminals. The present invention relates to a mounting structure for a lamp with a light reflecting plate suitable for connection.

0002

[Conventional technology]

Many of these types of lamp and fuse connection devices do not have a light reflector. For example, there is a conventional method described in Japanese Utility Model Publication No. 50-36658.

0003 This conventional technology involves bending an elastic, good-conductor metal plate into a U-shaped cross section. A pair of long holes are drilled on both sides, and a taper that slopes inward at both ends of the metal plate. An arc-shaped support is provided to hold the surface and both ends of a cylindrical fuse or straight tube lamp. An engagement device that includes a fuse holder and a pair of locking recesses facing the elongated hole of the holder. Provide a projection on the side edge of the fuse holder attachment part of the fuse box body, and A fuse made of insulating material is provided with multiple pairs of rectangular holes so that the tool can be attached from the bottom. It forms the fuse box body and is locked to the side edge of the mounting hole of this fuse box body. An engaging protrusion with a recess for use is provided, and this By providing a long hole to fit into the protrusion, one side of the long hole is used for locking the engagement protrusion. It is configured so that it can be fitted into the recess and removably engaged with the fuse holder. This fuse box is characterized by:

0004

[Problem that the idea aims to solve]

The conventional technology described above connects the fuse or straight tube lamp holder to other conductive members. When connecting, solder the lead wire etc. to the fuse holder or connect it to the bus bar. This is a device in which narrow conductive plates in the form of strips are connected by caulking.

[0005] Therefore, this conventional technology requires connection tools such as soldering irons and caulking tools. In addition to this problem, the above connection work is troublesome, especially in the engine room of a car. It cannot be connected in narrow or dark places, and there is also a light reflector that reflects the light emitted from the lamp. Since there is no one, it has to be attached separately, which is a big problem in terms of implementation. It was.

[0006] In addition to these problems, fuses and straight tube lamp holders may be When installing on a conductive plate such as a fuse or straight tube lamp, use a special insulating bush. Since it was necessary to insert each piece into the metal fittings, it was complicated and workability was poor.

[0007] Furthermore, the contact parts of fuses and straight tube lamp holders generate heat due to electric current. , the fuse and the entire lamp box are made of expensive heat-resistant plastic such as 66 nylon. There were many problems in that it needed to be made with.

[0008] This idea integrates a light reflecting plate into the connector itself in order to eliminate each of the problems mentioned above. This eliminates the need for a separate reflector and eliminates the need for connection tools. This makes it possible to easily and reliably connect other conductive materials to the socket type connector. , and the assembled structure of the connector can be used with any conductive or non-conductive material with good compatibility. The purpose is to make it easy to install.

[0009]

[Means to solve the problem]

The purpose of this invention described above is to provide an insulating base formed of an insulating material into a substantially rectangular parallelepiped frame shape, A plurality of locking hook pieces and a collar piece protruding from the side pieces of the insulating base and a length of the insulating base Two pairs of side piece relief holes formed from the inner surface of the side pieces on both sides in the longitudinal direction, respectively. , a pair of protrusions protruding from each opposing surface of these two pairs of opposing pieces, and an elastic conductor. The electric plate is formed into a roughly U-shape and is integrally equipped with a pair of clamping pieces and a light reflecting plate. and two connectors with lead wires, and connect these two connectors to the same light reflecting plate. Attachment holes formed at the base of the clamping piece in such a direction that the opposing protrusions are Connector assemblies installed between the two halves and the planar contour of the insulating base and a body to be attached with a large attachment hole formed therein, and the connector assembly is attached to the locking hook piece. This can be achieved by attaching it to the object to be attached using the attachment hole and the collar piece.

0010

[Effect]

When the outer surface of the locking hook of the insulating base is press-fitted between the edges of the mounting hole of the object to be mounted, the side After the piece bends against the elasticity in a direction that narrows the side relief hole, the locking hook piece is removed. When it comes off the edge of the mounting hole, the side piece returns to its original position and is locked with a single snap. The connector assembly can be easily attached to the object to be attached using the mounting hole in a loose “cassette pop” style. Wear.

[0011] In this mounted state, the vertical movement of the insulating base relative to the object to be mounted is The hook edge of the locking hook piece and the top surface of the collar piece are in contact with both the upper and lower surfaces of the object to be attached, respectively. It can be regulated from the ground up, and there will be no wobbling.

0012 In addition, the horizontal movement of the insulating base can be regulated by the periphery of the mounting hole of the object to be mounted, so there is no wobbling. .

[0013] By integrally forming a pair of clamping pieces and a lead wire connection part in one connector, straight pipes can be easily The lamp can be tightly held and used with a pair of clamping pieces, and when used in this way, the lamp The light can be reflected in the desired direction by the light reflector m, providing efficient lighting. can. In addition, the connection fitting installation structure, that is, the connection fitting assembled structure, has two fittings. Since it is surrounded by an insulating base, two connectors can be connected through this base regardless of whether it is a conductive plate or an insulating plate. Can be implemented with good compatibility.

【Example】

Examples will be described with reference to the drawings. First of all, the basic configuration of this idea is as shown in Figures 1 and 2. A frame-shaped insulating base 1 made of heat-resistant plastic, etc. Number of locking hook pieces 2a, 2a and collar pieces 2b, 2b, and both sides of the insulating base 1 in the length direction There are elongated side piece escape holes 3a, 3a from the inner surfaces of the side pieces 1a, 1a, respectively. two sets of opposing pieces 3,3 that form a pair; The insulating base 1 is constituted by the pair of protrusions 4,4.

[0015] In addition, as a connector 7, an elastic conductive plate as shown in Figure 3 is formed into a roughly U-shape as shown in Figure 4. The two connectors are each integrally equipped with a pair of clamping pieces 5, 5 and a lead wire connection part 6. Use fittings 7,7.

[0016] These two connectors 7,7 are attached to mounting holes 8, which are formed at the base of the clamping pieces 5,5. 8, through the pair of protrusions 4, 4, the state shown in FIGS. As shown in FIG. 9, the connector assembly 9 is constructed by attaching the connectors to the connector insertion holes.

[0017] A mounting hole 10 that is slightly larger than the planar outline of the insulating base 1 is used as the mounting object 11. The attached body 11 is constructed as shown in FIG.

[0018] Then, the connector assembly 9 is attached to the locking hook pieces 2a, 2a and the collar pieces 2b, 2b. The body 11 undergoes the state shown in FIGS. 10 and 11, and then as shown in FIGS. 1 and 12. It is inserted into the attachment hole 10 and attached.

[0019] In addition, the part indicated by the symbol 11a in Figures 1 and 5 is a relief provided as necessary. It is a hole.

[0020] Next, a specific example of the attachment structure of the connector of this invention will be described in more detail.

[0021] The insulating substrate 1 is made of a durable material such as 66 nylon or polybutylene terephthalate. By molding thermoplastic, a predetermined interval is provided on the upper surface side as shown in Figure 2. to form insertion holes 3b, 3b for the two connectors 7, 7, and the insertion holes 3b are as shown in the figure. A hole is formed on the lower surface side of the insulating base 1, and the connecting tool 7 is locked on the opposing inner wall surface. A pair of protrusions 4,4 are provided.

[0022] Connector 7 is a conductive plate made of conductive plate spring material such as phosphor bronze, nickel silver, beryllium copper, etc. Punch it out as shown in Figure 8, and form it into an almost U-shape as shown in Figure 4, with the bottom formed at the central branch. The bottom part The lead wire connection portion 6 extending from the side of the After that, use a well-known crimping tool to crimp and connect the stranded lead wire 6a as shown in Figure 4. , used by soldering.

[0023] The side edge of the light reflecting plate m protruding from the opposite side of the lead wire connection part 6 is shown in FIG. The lamp clamping pieces 5,5 are bent toward the opening side.

[0024] At the base of the above-mentioned clamping pieces 5, 5, there is a mounting in which the protrusions 4, 4 of the connector insertion hole 3b are inserted and locked. There is a gap between the mounting holes 8, 8, the reinforcement of the clamping pieces 5, 5, and the opposing piece 3 of the connecting tool insertion hole 3b. The ribs 18, 18 are formed to form a chimney effect for heat radiation.

[0025] This connector 7 is formed at each base of a pair of clamping pieces 5,5 as shown in Figure 4. Before mounting mounting holes 8, 8 are provided to protrude oppositely from the opposing piece 3 of the connector insertion hole 3b of the insulating base 1. The projections 4, 4 undergo the state shown in FIGS. 7 and 8, and then the elasticity of the clamping pieces 5, 9, snap it in and mount it to make the connector assembly 9 as shown in Figure 6. Note that the light reflecting plates m are mounted so that there is a gap of about 1 mm between the opposing parts. .

[0026] In addition, the object 11 to be attached is made of plastic or metal plate, and as shown in FIG. The connecting fitting assembly 9 has a mounting hole 10 that is slightly larger than the planar contour of the insulating base 1. into the attachment hole 10 of the object to be attached 11 with the locking hook pieces 2a, 2a and the collar pieces 2b, 2b as shown in Fig. 10. The components are inserted and mounted as shown in FIG. 12 in the order shown in FIG.

[0027] That is, in this case, the outer surface of the locking hook 2a of the insulating base 1 is connected to the attachment hole 10 of the object 11 to be attached. When press-fitting between the edges, the side pieces 1a, 1a resist the elasticity of the side pieces relief holes 3a, 3. After the locking hook piece 2a is pushed in the direction where it becomes narrower as shown in Fig. 11, the locking hook piece 2a is inserted into the attachment hole The side pieces 1a, 1a return to their original positions and snap as shown in Figure 12. With a single lock, the connector assembly 9 can be attached to the object 11 in a so-called "cassette pop" style. It can be easily installed through its mounting hole 10.

[0028] In this attached state, the insulating base 1 can move in the vertical direction with respect to the mounted object 11. The hook edge of the locking hook piece 2a and the top surface of the collar piece 2b are the upper and lower surfaces of the attached body 11, respectively. Since it is in contact with the ground, it is regulated and does not wobble. In addition, the horizontal movement of the insulating base 1 is restricted by the periphery of the mounting hole 10 of the mounted body 11, so that no wobbling occurs. There is no money.

[0029] As shown in Figure 13, between the pair of clamping pieces 5, 5 there is a connection lead for a straight tube lamp L, etc. Insert the electric parts l, l, and create an opposing gap between the two light reflecting plates m, m as shown in Fig. 14. Keep and use the program.

[0030] When this is used, the light emitted from the lamp L is reflected on the surface of the light reflecting plate m as shown in Figure 15. The light is reflected towards the opening side of the lamp clamping pieces 5,5 as shown by the arrow in the figure to efficiently illuminate the outside. can be done.

[0031] Furthermore, FIGS. 16 and 17 show other embodiments of this invention, as shown in FIG. In another embodiment, the edge of the mounting hole 10 of the object 11 to be mounted is raised to form a picture frame shape, so that it can be mounted in the mounting state. The lower surface of a certain insulating substrate 1 and the lower surface of the mounted object 11 are made flush as shown in FIG. It is.

[0032] Further, FIG. 17 shows another embodiment of this invention, in which the hook of the locking hook piece 2a is This is an example in which the protruding dimension of the part is reduced to facilitate attachment to the attachment hole 10 of the attachment target 11.

[0033] Note that the figures in FIGS. 16 and 17 are the same as the embodiments shown in FIGS. 1 to 15. Parts indicated by one symbol indicate the same parts or equivalent parts as each part shown in the above embodiment.

[0034]

[Effect of the idea] Since this invention is configured as explained above, it produces the effects described below. A clamp-type connector for connecting the electrodes of straight tube lamps and small light bulbs to a power source. A light reflecting plate m is integrally formed on the lamp so as to reflect the light emitted from the lamp in a desired direction. As a result, efficient lighting can be achieved without the need to separately install a light reflector on the lamp housing. The first effect is that it can be implemented in terms of space and economy.

[0035] Also, a locking hook piece 2a and a collar piece 2b formed on the insulating base 1 constituting the connector assembly 9 Since it is strongly integrally molded with the base side piece 1a, it is mechanically robust and can be easily covered. After mounting on the mounting body, the insulating base does not move unexpectedly and can be used stably for a long time. There are 2 effects.

[0036] Furthermore, the assembled structure of the connectors 7,7 is such that the connectors 7,7 are surrounded by the insulating base 1. The two connectors 7, 7 can be connected via this insulating base 1 to ensure compatibility regardless of whether they are conductive plates or insulating plates. The third effect is that it can be easily implemented.

[0037] Furthermore, the insulating substrate 1 that enables heat resistance is relatively small and the amount of resin used is Since only a small amount of molding is required, even if molded with expensive heat-resistant plastic, it is still cost-effective. In addition to being economical, it is especially expensive to use heat-resistant plus for relatively large insulating plates to be mounted. The fourth effect is that the overall cost is lower because there is no need to use ticks. be.

[0038] In particular, this idea requires a large number of straight tube lamps and small light bulbs to be concentrated in a narrow space. When installing, attach the insulating base 1 to which two connectors have been attached to the object to be attached using the locking hooks 2a, 2a. It can be mounted in the mounting hole 10 of 11 in a so-called "cassette pop" style, making it extremely easy to install. It can be arranged and mounted in an orderly manner, and since there are four relief holes 3a on the side pieces, the opposing pieces 3, The fifth effect is that the heat dissipation effect of the connectors 7 and 7 is excellent, and high-density mounting is possible. has.

[0039] Furthermore, this invention eliminates the need for soldering irons and screws, which were necessary in the prior art. No tools are required, and it can be used in narrow or dark places such as the engine room of a car. The sixth effect is that the connection work can be easily performed.
