[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wedge base lamp connector to which a wedge base lamp is mounted.

[0002]

2. Description of the Related Art A wedge lamp is used for lighting an ashtray of a vehicle. As shown in FIG. 4, the wedge base lamp 1 has a light emitting part 2 and a wedge part 3 whose insides are sealed and integrally formed of glass, and two lead wires 4 from inside the light emitting part 2. 4 are drawn out on both sides of the wedge portion 3, respectively. A connector to which such a wedge base lamp 1 is attached is disclosed in
There is one described in Japanese Patent No. 7082.

FIG. 5 shows a connector 5 described in the publication. The connector 5 includes a cylindrical housing 6 and a pair of terminals housed in the housing 6 (see FIG. 6).
7 and 7. An insertion opening 8 into which the wedge portion 3 of the wedge base lamp 1 is inserted is formed at an upper end portion of the housing 6. As shown in FIG. 6, the terminal 7 housed in the housing 6 has a wire crimping connection portion 9 formed on one side and one side 3a of the wedge portion 3 on the other side.
(See FIG. 4), a side holding portion 10 into which the insertion is made is formed.
Between the side holding portion 10 and the wire crimping connection portion 9,
Elastic connection pieces 11, 11 to which one of the lead wires 4, 4 drawn out to the wedge portion 3 is connected are formed. The terminals 7 are housed in a pair in the housing 6 with the side holding portions 10 facing each other.

Then, both side portions 3a, 3b of the wedge portion 3
Are inserted into the side holding portions 10, respectively, and the two lead wires 4, 4 are electrically connected to the elastic connection pieces 11, 11, and the lead wires 4, 4 are connected to the electric wires 12, 12. It has become so.

However, since the terminal 7 is crimped and connected to the terminal portion of the electric wire 12, the covering member of the terminal portion of the electric wire 12 is peeled off, and the stripped portion is placed at a predetermined position of the terminal and crimped. It is necessary to tighten. Because of this, it takes time,
This was an obstacle to cost reduction.

In the structure in which the terminal 7 is crimped and connected to the end of the wire 12, the terminal 7 in a state where the wire crimping connection portion 9 and the wire end are crimped in advance is assembled in the housing 6. . That is, when the terminal of the wire 12 is crimped to the wire crimping connection portion 9 of the terminal 7, a dedicated crimping device is used. Therefore, before the terminal 7 is housed in the housing 6, the terminal of the wire 12 is crimped. It had to be connected to the fastening connection 9. For this reason, the manufacturing procedure is limited, which has been an obstacle to cost reduction.

Therefore, a terminal 13 using a press-contact structure that can easily connect the terminal of the electric wire and the terminal is conceivable. As shown in FIG. 7A, the pressure contact structure of the terminal 13 is such that an electric wire insertion groove 14 is integrally provided on one side,
The press contact blades 15 are protruded from both sides toward the inside. Then, with the end of the wire 12 covered with the covering member, the wire 12 is pressed into the wire insertion groove 14 as it is, and the press-contact blades 15, 15
The coating member is peeled off to bring the press contact blades 15 and 15 into electrical contact with the core wire.

[0008] According to this press-contact structure, it is not necessary to peel off the cover member of the end of the electric wire 12 or to crimp it.
Manufacturing costs can be reduced.

Further, since the electric wire 12 is merely press-fitted between the press-contact blades 15, 15, it is possible to insert the electric wire 12 between the press-contact blades 15, 15 with the terminal 13 accommodated in the housing 14. In this case, the housing 6 includes the terminal 1
Any configuration may be used as long as the third press contact blade 15 can be exposed to the outside, for example, a configuration in which the terminal accommodating portion accommodating the terminal 13 can be opened and closed by a lid or the like.

[0010]

However, in the above-mentioned press-contact structure, the electric wire together with the covering member is press-fitted between the press-contact blades 15, 15 and the covering member is peeled off by the press-contact blades 15, 15. 15 and 15 need a certain length L1 (height), and when trying to secure this length L1,
The shape is as shown in FIG.

That is, the direction in which the side portion 3a of the wedge portion 3 is inserted into the side holding portion 10 of the terminal 13 (the direction of arrow a).
And the direction in which the electric wire 12 is press-fitted (the direction of the arrow b) is set in the same direction, and a press-contact blade having a required height L1 is formed. , The terminal 1 by the height L1 of the press contact blade 15
Since the terminals 3 and 13 are separated from each other, the distance between the pair of terminals 13 and 13 is longer than the width L2 of the wedge portion 3 and the side portions 3a and 3b of the wedge portion 3 cannot be held by the side holding portions 10 and 10. Would.

For this reason, as shown in FIG. 7A, the direction in which the side portion 3a of the wedge portion 3 is inserted into the side holding portion 10 of the terminal 13 (the direction of arrow a) and the direction in which the electric wire 12 is pressed (arrow). The distance between the pair of terminals 13 and 13 is narrowed by setting the distance between the terminals 13 and 13 by 90 ° so that the distance between the terminals 13 and 13 does not become longer than the width L2 of the wedge portion 3.

However, if the direction in which the side portion 3a of the wedge portion 3 is inserted into the side holding portion 10 of the terminal 13 and the direction in which the electric wire 12 is press-fitted are set to be shifted by 90 °,
Terminals of the same shape cannot be accommodated and arranged in the housing 6 with the terminals facing each other, and the terminals 16 having different shapes of the positions of the wire connection portions must be set as shown in FIG. 7B. For this reason, twice the number of molds is required, which increases the manufacturing cost of the terminals.
