Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a conductive terminal provided with a lamp pin connection terminal and a quick connection terminal of a lighting fixture.
[0002]
[Prior art]
As a conventional example 1, there is Japanese Utility Model Laid-Open No. 5-15378. The conductive fitting housed in the body of the socket is integrally formed with a lamp pin holding portion on one end side and a quick connection terminal portion on the other end side. The lamp pin holding part is located in the extending direction of the electric wire connection surface (base piece) of the quick connection terminal part, and is formed by bending a strip-like conductive plate having substantially the same width.
[0003]
As a conventional example 2, there is JP-A-9-293574. In this case, the contact conductor incorporated in the socket body is formed with a pin contact end portion and a lock piece portion by press molding. The pin contact end is provided at one end in the longitudinal direction of the contact conductor, and the locking piece is bent at the other end in the longitudinal direction of the conductor. The locking piece portion elastically contacts an electric wire inserted into an electric wire insertion hole provided in the socket body, but is configured to lock between the holding surface of the socket body. Further, the lamp pin insertion direction at the pin contact end portion and the insertion direction of the electric wire fast connected to the locking piece portion coincide with each other.
[0004]
[Problems to be solved by the invention]
In Conventional Example 1, the width of the lamp pin connection terminal portion and the width of the quick connection terminal portion are substantially the same. Taking an LED connector as an example, the load is small current and low voltage, so the quick connection terminal may be narrow, but it is difficult to narrow the lamp pin connection terminal part as well. The total thickness when attached cannot be reduced. This is because a wide deflection allowance is necessary in consideration of variations such as the pitch and thickness of the lamp pins, and the spring portion needs to have a wide width and length in order to ensure contact force.
[0005]
In Conventional Example 2, since the insertion direction of the lamp pin insertion direction coincides with the insertion direction of the fast-connecting wire, the position of the wire insertion hole cannot be brought closer to the inside than the lamp projection range. In connection with this, since the terminal part (locking piece part) located in an electric wire insertion hole cannot adjoin to a pin contact end part, a shape becomes large.
[0006]
Accordingly, an object of the present invention is to provide a conductive terminal capable of reducing the width of the quick connection terminal and reducing the size.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the conductive terminal according to claim 1 of the present invention is an electric wire which is bent into an L-shape composed of one piece and another piece, and is cut and raised so that the tip of the one piece faces the other piece. A conductive plate having a locking piece and having the other piece as an electric wire connection surface;
A lamp terminal that extends from a side edge of the one piece in the vicinity of a support end portion that is a base of the one piece of the wire locking piece, and is bent in the extending direction of the other piece. ,
The lamp terminal has a rectangular ring shape including a pair of long sides and a pair of short sides. The pair of contact pieces that sandwich the lamp pin are bent from the inside of the pair of long sides so as to be opposed to each other and can be elastically deformed .
[0008]
In this way, the lamp terminal that connects the lamp pin is provided on the side of the quick connection terminal that connects the power line, so the lamp terminal and the quick connection terminal are separated, but by connecting the two on the side of the quick connection terminal, It is united. For this reason, the width of the lamp terminal and the length of the quick-connection terminal are overlapped, the range occupied by the entire length can be narrowed, and the size can be reduced. Moreover, the width of the quick connection terminal can be narrowed by the reinforcing effect of connecting the quick connection terminal and the lamp terminal.
[0009]
In addition, since the position where the lamp terminal and the quick connection terminal are connected is the vicinity of the support end of the electric wire locking piece of the quick connection terminal, the connecting portion near the support end of the electric wire locking piece (the bending force is The connecting portion with the lamp terminal is arranged on the side surface of such a portion), and the force applied to the support end portion of the wire locking piece is shared by the lamp terminal. For this reason, the width of the quick connection terminal can be reduced. Moreover, since a connection part supports the support end part of an electric wire locking piece, the spring load (contact load) of an electric wire locking piece rises and electricity supply performance improves.
[0010]
Furthermore, since the electric wire connection surface of the quick connection terminal is bent toward the lamp terminal, the bending direction of the locking piece and the inserted electric wire are accommodated in the longitudinal space of the lamp terminal. For this reason, an electric wire storage space can be narrowed.
