Description

Detailed Description of the Invention

[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 attached.

[0002]

2. Description of the Related Art Wedge lamps are used for ashtray lighting of vehicles. As shown in FIG. 4, in the wedge base lamp 1, a light emitting portion 2 whose inside is hermetically sealed and a wedge portion 3 are integrally formed of glass, and two lead wires 4 are formed from inside the light emitting portion 2. 4 are drawn out to both sides of the wedge part 3. As a connector to which such a wedge base lamp 1 is attached, as shown in Japanese Utility Model Laid-Open No. 54-14
There is one disclosed in Japanese Patent Publication 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).
It consists of seven and seven. An insertion opening 8 into which the wedge portion 3 of the wedge base lamp 1 is inserted is formed in the upper end portion of the housing 6. Further, 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 portion 3a of the wedge portion 3 on the other side.
(See FIG. 4) is formed a side holding portion 10 is inserted,
Between the side holding part 10 and the wire crimping connection part 9,
Elastic connecting pieces 11 and 11 to which one of the lead wires 4 and 4 drawn out to the wedge portion 3 are connected are formed. A pair of the terminals 7 are housed in the housing 6 with the side sandwiching portions 10 facing each other.

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

However, since the terminal 7 is caulked and connected to the end portion of the electric wire 12, the covering member on the end portion of the electric wire 12 is peeled off, and the peeled portion is placed on a predetermined position of the terminal and applied. Need to tighten. Therefore, it takes time and effort,
It was an obstacle to cost reduction.

Further, in the structure in which the terminal 7 is caulked and connected to the end of the electric wire 12, the terminal 7 in which the electric wire caulking connection portion 9 and the electric wire end are caulked and connected in advance is assembled in the housing 6. . That is, when the end of the electric wire 12 is to be caulked to the electric wire caulking connection portion 9 of the terminal 7, a dedicated caulking device is used. Therefore, before the terminal 7 is housed in the housing 6, the end of the electric wire 12 is crimped. It was necessary to connect to the fastening connection 9. For this reason, there are restrictions on the manufacturing procedure, which has been an obstacle to cost reduction.

Therefore, a terminal 13 using a pressure contact structure that enables the terminal of the electric wire and the terminal to be easily connected can be considered. As shown in FIG. 7A, the pressure contact structure of the terminal 13 has an electric wire insertion groove 14 integrally formed on one side thereof.
The pressure contact blades 15 and 15 are provided so as to project from both sides toward the inside. Then, with the end of the electric wire 12 covered with the covering member, the electric wire 12 is pressed into the electric wire insertion groove 14 as it is, and the press contact blades 15, 15
The covering member is stripped off to electrically contact the press contact blades 15 and 15 with the core wire.

According to this pressure contact structure, it is not necessary to peel off or crimp the covering member at the end of the wire 12.
Manufacturing costs can be reduced.

Further, since the electric wire 12 is simply press-fitted between the press contact blades 15, 15, the electric wire 12 can be inserted between the press contact blades 15, 15 with the terminal 13 accommodated in the housing 14. In this case, the housing 6 is the terminal 1
It is sufficient that the pressing blade 15 of No. 3 can be exposed to the outside, for example, the terminal accommodating portion for accommodating the terminal 13 can be opened and closed by a lid or the like.

[0010]

However, in the pressure contact structure as described above, the electric wire is press-fitted between the pressure contact blades 15 and 15 together with the covering member, and the covering member is peeled off by the pressure contact blades 15 and 15. 15 and 15 require 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 (direction of arrow a).
And a direction in which the electric wire 12 is press-fitted (direction of arrow b) is set to the same direction to form a press contact blade having a required height L1, in a structure in which the pair of terminals 13 and 13 are housed facing each other in the housing 6. , Terminal 1 only for the height L1 of pressure 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 dimension L2 of the wedge portion 3, so that both side portions 3a and 3b of the wedge portion 3 cannot be held by the side holding portions 10 and 10. Will end up.

Therefore, 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 (direction of arrow a) and the direction in which the electric wire 12 is press-fitted (arrow) are shown. By setting the angle b and the angle b by 90 °, the distance between the pair of terminals 13 and 13 is narrowed so that the distance between the terminals 13 and 13 is not longer than the width dimension 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 offset by 90 ° in this way,
The terminals having the same shape cannot be housed and arranged in the housing 6 in a state of facing each other, and as shown in FIG. 7B, the terminals 16 having different shapes of the wire connection portions must be set. For this reason, the number of molds required is doubled, which increases the manufacturing cost of the terminal.

Therefore, an object of the present invention is to provide a wedge base lamp connector capable of sandwiching both sides of a wedge portion with terminals having the same shape and reducing the manufacturing cost.
