The upper pressing piece 3 is provided at the center of the elastic piece 61 located at both sides of the first elastic supporting terminal 6a and has a central portion bent so as to have an elastic force without contact with the electrical terminal, As shown in FIG.

The wedge bulb support part 45 is formed by a single wedge bulb or a single wedge bulb in which only one electric terminal is exposed using a single filament in a structure in which a pair of electric terminals are located in a socket for a dual wedge bulb, But only one filament is used to electrically connect only one electrical terminal and is located at the same position as the electrical terminal of the dual wedge bulb but is connected to one of the pair of electrical terminals And is intended to support the connection portion 42 instead of the other empty electrical terminal or elastic support terminal.

2A, the wedge bulb supporting portion 45 is provided with a support rib 451 (see FIG. 2A) formed in the socket housing 5 so as to be located at a place where another empty electrical terminal should be located, ).

The supporting rib 451 is integrally formed on the inner surface of the socket housing 5 so as to contact the connecting portion 42 when the connecting portion 42 is inserted into the coupling groove 51 of the socket housing 5, Even if the connecting portion 42 of the single wedge bulb having only one electronic terminal 43 is inserted as shown in Fig. 2B, the gap between the socket housing 5 and the connecting portion 42 And supports the connection portion 42 while being in contact with the connection portion 42.

2C, the first elastic support terminal 6a is formed to support the entire one surface of the connection portion 42, so that the front surface 42a of the connection portion 42 is connected to the first elastic support terminal 6a by the first elastic support terminal 6a And the rear surface 42b of the connection portion 42 is supported by the second elastic support terminal 6b and the support rib 451 to prevent a gap between the socket 5 and the connection portion 42 from being generated do.

2D, when the first resilient supporting terminal 6a 'is formed to have a short length so as to support only the electrical terminal 43, the supporting rib 451 is also provided on the front surface 42a of the connecting portion 42 As a result, it is possible to prevent a gap from being generated between the socket 5 and the connecting portion 42, as described above.

Further, the wedge bulb support portion 45 may further include a contact rib 453, as shown in Fig. 3A. The contact rib 453 can support the connection portion 42 when only an electric terminal connected to both ends of the filament of one of the pair of electric terminals of the single wedge bulb or the dual wedge bulb is used, The second resilient supporting terminal 6b is provided in the socket housing 5 but the empty space is formed between the other unused electric terminal and the socket housing 5 so that the connecting rib 453 is formed between the connecting portion 42 and the socket housing 5, (5).

3B, the connection rib 453 is formed inside the socket housing 5 and has a second elastic support terminal 453 electrically connected to one electrical terminal 43 connected to one filament, Is formed integrally with one of the electric terminals connected to the other filament (6b) and contacts the connecting portion (42) to support the connecting portion (42).

3B, the front surface 42a of the connection part 42 is formed so as to support the entire surface of the connection part 42 and is provided with a first The rear surface 42b of the connecting portion 42 is supported by the elastic supporting terminal 6a so that the second elastic supporting terminal 6b provided on the socket is brought into contact with the connecting portion 42 so as to be connected to the electric terminal connected to the filament to be used And is supported by a contact rib 453 formed in the socket.

3C, when the first elastic support terminal 6a 'is formed so as to be connected only to the electrical terminals to be used, the contact ribs 6a' are also formed between the unused electrical terminals and the first elastic support terminals 6a ' 453 may be additionally provided to support the connection portion 42.

Since the connection rib 453 is located at a position where it is not interfered with the electric terminal or the elastic support terminal, a single wedge bulb in which only one electric terminal is exposed or a pair of electric terminals is exposed, It is of course possible to form them all in the socket for the wedge bulb.

4 is a side view of a wedge bulb inserted into a socket for a single wedge bulb according to the present invention.

4, when the connection part 42 is inserted into the socket housing 5, the second elastic support terminal 6b provided on the support terminal installation part 551 and the first elastic support terminal 6a are connected to the connection part 42 The first and second resilient supporting terminals 6a and 6b are urged by the resilient force of the elastic pieces of the first and second resilient supporting terminals 6a and 6b. The protrusions of the connection portion 42 are seated on the contact support ribs 441a and 441b to be described later so that the gap between the connection portion 42 and the socket housing 5 by the terminal position support rib 451 and the contact rib 453 And the connecting portion 42 is supported to prevent the connection failure of the electric terminal from being caused by the external impact.

Figures 5a and 5b show one embodiment and another embodiment of a socket for a single wedge bulb according to the present invention and Figure 6 shows a socket for a wedge bulb according to the present invention in which a single wedge bulb is inserted FIG.

As shown, the single wedge bulb support portion 45 is provided on the inner surface and the upper portion of the socket housing 5 to guide the insertion of the single wedge bulb and to support the connection portion 42 of the inserted single wedge bulb, (451) and a plurality of guide ribs (455a, 455b).

2, which is referred to again in the case where the light emitting portion 41 is white in the single wedge bulb, the bulb dividing projections 42 formed on the front surface 42a and the rear surface 42b of the connecting portion 42, respectively, An upper protrusion 441b formed to have a relatively narrow width so as to contact with the electrical terminal 43 exposed at the upper end and a lower protrusion 441b formed at the center of the connection portion 42. The upper protrusion 441b And a center protrusion 441c formed adjacent to the center protrusion 441c.

The upper protrusions 441b and the lower protrusions 441a are inclined so as to protrude to the outside of the connection portion as they go downward and the center protrusions 441c are formed to be inclined so as to protrude to the outside of the connection portion toward the upper side.

The guide ribs 455a and 455b for separating the coupling grooves 51 in accordance with the positions of the protrusions formed on the front surface 42a and the rear surface 42b of the connection portion 42 are formed on the socket 5a on which the white single wedge bulb is inserted, Are formed.

That is, on the side contacting the rear surface 42b of the connection part 42, there is provided an upper protrusion guiding rib (not shown) which is in contact with one side of the upper protrusion 441b at one side so as to guide insertion of the upper protrusion 441b formed with a relatively narrow width 455a are formed on the other side of the lower projection 441a and the lower projection 441a is formed on the other side so as to secure a space corresponding to the length of the lower projection 441a and to guide the lower projection 441a, A lower projection guide rib 455b is formed. Then, the center protrusion 441c is inserted into the space between the upper protrusion guiding rib 455a and the lower protrusion guiding rib 453b, and guided by the guiding ribs, and guided by the side surfaces thereof.

It is a matter of course that the front surface 42a of the connection portion 42 is formed to be opposite to the above-described manner and can guide the insertion of the connection portion 42 as described above.

The support ribs 451 formed in the coupling grooves 51 minimize the clearance between the connection portions 42 and the coupling grooves 51 and reduce the contact area between the coupling portions 42 and the coupling grooves 51 And is configured to support the connection portion 42 and to be in contact with the lower surface of the upper protrusion 441b and the lower protrusion 441a.

The center projection 441c supports the position of the upper pressing piece 33 while contacting the upper pressing piece 3 on the upper surface.

The coupling recess 51 of the socket housing 5 is provided with an upper protrusion 441b formed on the other side of the connecting portion 42 and a coupling recess 51 formed on the lower protrusion 441a, The upper protrusion supporting ribs 457b are relatively long in contact with the lower surface of the upper protrusion 441b on the other side of the inner surface of the defect groove 51 and have a relatively long length corresponding to the length of the upper protrusion 441b, A lower projection supporting rib 457a having a relatively short length and a relatively short length corresponding to the length of the lower projection 441a is formed on one side so as to contact the lower surface of the lower projection 441a.

Therefore, it is needless to say that the lengths of the upper and lower projection supporting ribs 457a and 457b can be freely changed in accordance with the positions of the upper and lower protrusions 441b and 441a.

5B, a single wedge bulb different from the above-described single wedge bulb, for example, a single wedge bulb having a yellow light emitting portion 41 so as to be used for a turn signal lamp of an automobile, The upper surface of the upper protrusion 441b formed on the upper side of the other side and the lower protrusion 441a formed on the lower side of the lower surface of the lower surface of the upper surface of the upper surface of the upper protrusion 441b, The upper projection supporting rib 457b 'formed in the coupling groove 51' of the socket housing 5 'and the lower projection 441a formed on one side of the inner surface of the defect groove 51' And is coupled to the coupling groove 51 'of the socket housing 5' to have a relatively short length so as to contact the lower surface of the socket housing 5 'and to contact the lower projection support rib 457a' formed to fit the length of the lower projection 441a.

Here, the formation position of the guide ribs is different from the position of the socket shown in Fig. 5A.

More specifically, in order to prevent the single wedge bulb whose light emitting portion is yellow from being assembled with the white single wedge bulb described above during the assembling process, the sizes and positions of the respective projections may be different.

Therefore, the protrusions of the yellow single wedge bulb and the protrusions of the above-described transparent single wedge bulb vary in size, so that the transparent single wedge bulb has the guide ribs 455a, 455b as in the socket housing 5 shown in Fig. The yellow single wedge bulb can be inserted only into the socket housing 5 in which the guide ribs 455a 'and 455b' are disposed, as shown in FIG. 5b, 5 '.

The inner surface of the lower protrusion 441a of the connecting portion 42 is inserted into the lower protrusion 441a of the lower protrusion 441a of the socket housing 5, The connecting portion 42 starts to be inserted into the engaging groove 51 while being in contact with the side surface of the rib 455a.

The inner surface of the upper projection 441b is in contact with the outer surface of the upper projection guide rib 455a and one side of the center projection 441c is in contact with the inner surface of the lower projection guide rib 455b and the upper surface of the upper projection guide rib 455a The connecting portion 42 is inserted into the engaging groove 51. In this case,

At this time, when another type of single bulb is inserted, the upper protrusions 441b and the lower protrusions 441a are not allowed to enter the outer side of the guide ribs because the sizes of the upper protrusions and the lower protrusions are the same, It is possible to remarkably reduce the assembly failure rate in assembling the bulb and the socket.

An electric wire C connected to the first elastic support terminal and an electric wire C connected to the second elastic support terminal are drawn out to the back surface of the socket 5, respectively.

Here, since the dual wedge bulb has two electric terminals, each electric terminal is connected to the pair of second elastic supporting terminals, so that two outlets through which the connected electric wire C is drawn are formed.

On the other hand, since the single wedge bulb has one electric terminal, the second elastic supporting terminal is also provided, and the electric wire (C) drawn out to the outlet is also one.

Therefore, it is needless to say that the outlet is not formed on the side where the electric terminal is not drawn out, or it can be formed in a structure that can seal the outlet.

Therefore, the socket for wedge bulb as described above is provided with a conventional dual wedge bulb socket having a wedge bulb support portion for supporting an empty space at a connection portion of a single wedge bulb in which an electric terminal is not provided, The support rib, the contact rib, the upper and lower protrusion supporting ribs, and the upper and lower guide ribs can be formed by using the mold for manufacturing the bulb as it is, thereby reducing the manufacturing cost of the socket.

In addition, even if a conventional metal mold is used, occurrence of clearance between the socket and the connecting portion is minimized, so that the connecting portion is supported, so that even if an impact is applied from the outside, the connecting portion is prevented from being short-circuited. There is an effect.
