DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector used for connecting an electric wire and a board, or between electric wires or between boards, and particularly to a connection between a flat cable (FFC) or a flexible printed circuit (FPC) and a board. It relates to a connector to be used.

[0002]

2. Description of the Related Art As a connector used for connecting a conductive member, such as a flat cable or a flexible printed circuit, having a conductor portion provided on one surface of an insulating base to a substrate, FIG.
3 is conventionally known.

In the connector, an insertion recess 21 into which a terminal portion of the conductive member A is inserted is provided in a housing 20, and the insertion recess 2 is provided in a terminal 22 supported by the housing 20.
A pair of contact pieces 23, 23 arranged in 1 are provided, and a gap equal to or greater than the thickness of the conductive member A is formed between the tips of the contact pieces 23, 23. A tongue piece 25 inserted between the pair of contact pieces 23 is provided on a slider 24 provided slidably with respect to the housing 20, and an inclined surface 26 is formed at the tip of the tongue piece 25.

[0004] As shown in FIG. 4 (I), the connector has a pair of contact pieces 2 with the slider 24 pulled out.
Insert the conductor A between 3 and 23, by pushing the slider 24, as shown in FIG. 4 (II), the one contact piece 23 through the conductive member A are elastically deformed, by the restoring force due to the deformation The contact piece 23 and the conductive member A are pressed against each other and held in a connected state.

[0005] Further, the slider 24 is pulled out, and the conductive member A is pulled out in a state where the gap between the tip portions of the pair of contact pieces 23, 23 is opened to be equal to or more than the thickness of the conductive member A, thereby disconnecting the connection.

In the connector described above, the connection and disconnection of the conductive member A are performed by inserting and removing the slider 24, and the distance between the tips of the pair of contact pieces 23, 23 when the slider 24 is pulled out is determined by the conductive member. Since the thickness of the conductive member A is equal to or greater than the thickness of the conductive member A, the conductive member A can be inserted and removed without resistance, and has a feature that there is no possibility of damaging the terminal portion.

[0007]

However, in the above connector, the conductive member A can be easily inserted and removed, but a force is required to insert and remove the slider 24. The force at this time depends on the contact pressure P ₀ applied to the slider 24 and the slider 24.
And the number of terminals and the coefficient of friction between each member and the number of terminals in contact with the member.

Accordingly, as the number of terminals increases, the force for inserting and removing the slider 24 increases. For example, if the number of terminals exceeds 30, it becomes difficult to manually insert and remove the slider 24, resulting in poor workability.

In addition, since the contact piece 23 is elastically deformed by inserting the slider 24 to obtain a contact pressure, the slider 2 receives a shock such as a cooling / heating cycle.
Due to the difference in the coefficient of thermal expansion between the resin forming the terminal 4 and the metal forming the terminal 22, the slider 24 has a pair of contact pieces 23
There is a possibility that the conductive member A may fall out from the space between the three, and there is a problem in reliability of maintaining the conductive member A in a connected state.

The terminal 22 is a one-side contact in which one contact piece 23 contacts the conductive portion of the conductive member A and the other contact piece 23 contacts the slider 24. In order to obtain conduction between the conductive members A, it is necessary to insert the conductive member A in such a manner that the conductors of the conductive member A and the contact pieces 23 are oriented in the same direction, and the insertion direction is limited.

[0011] It is an object of the present invention to reduce the operating force when connecting and disconnecting a conductive member, to ensure that the conductive member can be maintained in a connected state, and to provide a conductive member that A technical issue is to eliminate the direction at the time of insertion.

[0012]

In order to solve the above problems, according to the present invention, there is provided a housing having an insertion recess into which a terminal portion of a conductive member is inserted, and a terminal having conductivity held by the housing. And inside the insertion recess
Consists of a slidably inserted slider said pair of contact pieces that are opposed to each other at a distance which can be inserted a conductive member provided in the terminal, the conductive member on each of the pair of contact pieces only setting a pair of contact portions to <br/> facing position in contact with the conductor portion of the front side of the contact portion in the one contact piece

To elastically deform the operation piece in the direction in which the pair of contact parts separate.
And an inclined surface to release the pressing of the operation piece when inserting
Is provided .

[0013]

In the connector having the above structure, when connecting the conductive member, the slider is pulled out and the slider is pulled out.
The operation piece is elastically deformed by contact with the inclined surface provided on the ida, and a gap between the pair of contact portions is opened to be equal to or more than the thickness of the conductive member, and then the conductive member is inserted between the contact portions. After the insertion, the slider is inserted, the pressing of the distal end of the operation piece is released, and the conductive members are pressed and connected by the pair of contact portions by the restoring elasticity of one of the contact pieces.

BRIEF DESCRIPTION OF THE PREFERRED embodiment of the present invention in FIGS.

As shown , the housing 1 is formed from an insulator. The housing 1 is formed with an insertion recess 2 that opens on one side of the outer periphery. On the other side of the housing 1, a number of terminal holding holes 3 communicating with the insertion recess 2 are provided in parallel.

A conductive terminal 4 attached to each of the terminal holding holes 3 has a first contact piece 6 and a second
The contact piece 7 and the support piece 8 are coupled, the holding portion 5 is inserted into the terminal holding hole 3, and the first contact piece 6 and the support piece 8 are fixed to the housing 1.

The first contact piece 6 and the second contact piece 7 are provided with contact portions 6a, 7a facing the conductive member A at opposing positions, and the distance between the pair of contact portions 6a, 7a is set at the conductive member A. It is smaller than the thickness.

An operating piece 9 extending into the insertion recess 2 of the housing 1 is provided at the tip of the second contact piece 7 in series. A projection 9 a is provided at the tip of the operation piece 9.

The lower surface of the top wall of the insertion recess 2 is provided with a guide surface 10 inclined toward the contact portion 6a of the first contact piece 6.

A step is formed on the upper surface of the slider 11 which is supported in the insertion recess 2 so as to be freely inserted and removed, and a high step surface on both sides is a guide surface 12 guided by the lower surface of the top wall of the insertion recess 2.
It has been. The low step surface between the guide surfaces 12 is
The guide surface 13 serves as a guide surface 13 for inserting and removing the conductive member A. The tip of the guide surface 13 is inclined in the same direction as the guide surface 10 of the insertion recess 2.

The slider 11 has a projection 1 at both rear portions.
4 is provided, and the amount of insertion of the slider 11 is limited by the abutment of the projecting portion 14 and the bulging portions 15 formed on the rear portions on both sides of the housing.

Are formed in the same number as the terminals 4, and an inclined surface 17 is provided on the upper surface of each of the insertion holes 16.

The inclined surface 17 extends from the insertion recess 2 to the slider 1.
At the time of pulling out 1, the projection 9 a of the operation piece 9 is pressed to press the operation piece 9 downward, and when the slider 11 is completely inserted into the insertion recess 2, the pressure of the projection 9 a is released. .

Now, as shown in FIG. 1, when the slider 11 is pulled out of the insertion recess 2, the inclined surface 17 of the slider 11 is removed.
Presses the projection 9a of the operation piece 9, so that the operation piece 9 is elastically deformed downward.

At this time, the operation piece 9 is elastically deformed downward around the coupled position of the second contact piece 7 and the holding portion 5, and the contact portion 7 a of the second contact piece 7 is displaced downward by the elastic deformation. Then, the gap between the contact portion 7a of the second contact portion 7 and the contact portion 6a of the first contact piece 6 is opened to the thickness of the conductive member A or more.

For this reason, by inserting the terminal portion of the conductive member A between the pair of contact portions 6a, 7a along the guide surface 13 of the slider 11, the terminal portion is connected to the pair of contact portions 6a.

The one inclined surface 17 releases the pressing of the projection 9A of the operation piece 9. Due to the release of the pressure, the second contact piece 7 moves toward the first contact piece 6 due to the restoring elasticity at the time of elastic deformation, and the contact portion 6a of the first contact piece 6 and the contact portion 7a of the second contact piece 7 conduct. The conductive member A is clamped from both sides, and the conductive member A is held in a connected state.

At this time, since the slider 11 is not involved in the connection of the conductive member A, the slider 11 does not come out of the insertion recess 2 even if an impact such as a cooling cycle is applied, and the conductive member A is connected. Can be securely held.

When disconnecting the conductive member A, the slider 11 is pulled out,
The projection 9a of the operation piece 9 is pressed by the inclined surface 17 of the
Is elastically deformed downward. Due to the elastic deformation, the contact portion 7a of the second connection piece 7 is displaced downward, and the space between the contact portions 6a and 7a of the first contact piece 6 and the second contact piece 7 is opened to the thickness of the conductive member A or more. The conductive member A is pulled out in the open state.

Here, the inclined surface 17 of the slider 11 is provided with a projection 9 at the tip of the operation piece 9 coupled to the tip of the second contact piece 7.
A, the force required to open between the contact portions 6a, 7a of the first contact piece 6 and the second contact piece 7 is reduced by the leverage principle, and even when the number of terminals is large, The slider 11 can be easily slid with a small force.
