Abstract

PROBLEM TO BE SOLVED: To provide an electric connector capable of preventing each terminal certainly from deforming when an insulating member is inserted into the terminal. SOLUTION: When the insulating member 20 is inserted into the terminal 10, pressure contact to the insulating member 20 is generated only by projectins 14 on the terminal 10 so that a deformation due to pressure contact is positively generated on the side with insulating member 20, and the force to spread the terminal from the inside at the time of insertion can be absorbed by the deformation of the insulating member 20.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connector for electrically connecting printed circuit boards, for example.

[0002]

2. Description of the Related Art Conventionally, as this type of electrical connector,
2. Description of the Related Art There has been known a device including a plurality of terminals arranged at an interval from each other and an insulator holding each terminal. This electrical connector is arranged between a pair of printed boards, and by joining each terminal to each board by soldering or the like,
The electrical connection between the substrates is performed.

As a general type of the electric connector, for example, as shown in FIG. 8, a terminal 1 is formed in a substantially U-shape, and an insulator is provided between one end 1a and the other end 1b of the terminal 1. 2 is inserted. In this electric connector, the terminal 1 is formed of a member having an elastic force so that one end 1a and the other end 1b approach each other.
The insulator 2 is sandwiched by the elastic force of the above.

However, in the electric connector, since the terminal 1 is easily elastically deformed even after the terminal 1 is mounted on the insulator 2, the terminal 1 is elastically deformed when mounted on each substrate. Cannot be reliably held, and the parallelism between the substrates is reduced.

Therefore, as shown in FIG. 9, an insulator 4 is press-fitted between the one end 3a and the other end 3b of the terminal 3, and the claws 3c provided on the one end 3a and the other end 3b of the terminal 3, respectively.
In some cases, the terminal 3 is held by the insulator 4 by locking the terminal 3 to the insulator 4 side.

In this case, since the terminal 3 is not held by the elastic force, no elastic deformation occurs even if the substrate is fixed as in the former case.

[0007]

However, in the latter structure, when the insulator 4 is inserted into the terminal 3, the upper surface side and the lower surface side of the insulator 4 in FIG. Excessive force is required to spread the terminal 3 against this pressure contact, and the pressure contact force is increased by the amount by which the claws 3c protrude. Therefore, the insulator 4
In some cases, the terminal 3 side may be deformed by the press-fitting, and the amount of deformation varies depending on each terminal 1. Therefore, the contact surface between each terminal 1 and the substrate becomes uneven,
There is a problem that the SMT (surface mounting technology) accuracy at the time of mounting on a substrate is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide an electric connector capable of reliably preventing deformation of a terminal when an insulator is inserted into the terminal. It is in.

Sides are formed so as to extend along one end face and the other end face of the insulator, respectively, and the insulator is inserted between one end side and the other end side of the terminal. A projection is provided between the other end and pressed against the insulator, and only this projection is pressed against the insulator.

Thus, when the insulator is inserted between one end and the other end of the terminal, only the protrusion of the terminal presses against the insulator, so that the pressing force concentrates on the contact portion between the protrusion and the insulator. In addition, deformation due to pressure contact positively occurs on the insulator side.

According to a second aspect of the present invention, in the electrical connector according to the first aspect, the protrusions of the terminal are provided on one end side and the other end side of the terminal at an interval from each other, and the insulator is provided at one end of the terminal. A holding portion inserted into a portion not including each projection between the side and the other end, and a press-fit portion press-fitted between the projections of the terminal are provided, and the holding portion of the insulator is connected to one end of the terminal and the other. It is formed so as to have a corresponding dimension substantially equal to the interval on the end side.

Thus, in addition to the operation of the first aspect, the portion between the one end and the other end of the terminal that does not include each protrusion is
Since the holding portion having a corresponding dimension substantially equal to the distance between the one end and the other end of the terminal is inserted, the terminal is insulated by the close engagement between the one end and the other end of the terminal and the holding portion. Is accurately held at a predetermined position.
