Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for controlling electrical connection between devices, and more particularly to a connector for an anti-lock brake device for controlling brake fluid pressure of an automobile. Regarding good connectors.

[0002]

2. Description of the Related Art This type of connector is disclosed in, for example,
As shown in FIG. 3 of JP-A-239217, a contact provided with an elastic socket portion into which a connecting pin is inserted and a lead portion extending from the elastic socket portion is provided inside a substantially cylindrical connector case made of a synthetic resin material. A member is provided, and an end of a lead portion extending from the elastic socket portion of the contact member is soldered to the electric circuit member.

[0003]

The elastic socket portion of the contact member resiliently contacts the connection pin to establish an electrical connection therebetween. Therefore, when the connection pin is inserted into the elastic socket portion, the elastic socket portion of the contact member is resiliently connected to the connection pin. Due to the friction between the elastic socket portion and the connection pin, a force in the insertion direction of the connection pin acts on the contact member.

However, in the above-mentioned conventional example, the contact member is only accommodated in the connector case, and no member for supporting the force in the insertion direction of the connection pin is provided between the two. The contact member is generally accommodated with a small gap between the contact member and the connector case in consideration of thermal expansion of the connector case made of a synthetic resin material.

For this reason, the force acting on the contact member when the connection pin is inserted, is applied to the portion where the end of the lead is connected to the electric circuit member via the lead extending from the elastic socket portion of the contact member. If the mechanical strength of the connecting portion is insufficient, the connecting portion may be separated.

The present invention has been made in view of the above-mentioned conventional circumstances, and can improve the reliability of a connection portion between an end of a lead portion extending from an elastic socket portion of a contact member and an electric circuit member. It is intended to provide a simple connector.

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a substantially cylindrical connector case, an elastic socket portion accommodated in the connector case and into which a connecting pin is inserted, and the elastic socket portion. A contact member having a lead portion extending from the contact portion; an electric circuit member to which an end of the lead portion extending from the elastic socket portion of the contact member is connected; and a connection member provided between the connector case and the contact member. And stopper means for supporting a force acting on the contact member when the pin is inserted.

According to a second aspect of the present invention, in the configuration of the first aspect, the stopper means is provided on a cut-and-raised tongue provided on an elastic socket portion of the contact member and on a connector case. And an engaging step portion with which the cut-and-raised tongue piece of the elastic socket portion engages.

According to a third aspect of the present invention, in the first aspect of the present invention, a flexible portion is formed on a lead portion extending from the elastic socket portion of the contact member. .

In such a configuration, a connection pin is inserted into the elastic socket portion of the contact member, and the connection pin elastically contacts the elastic socket portion to establish an electrical connection therebetween.

When the connection pin is inserted into the elastic socket portion of the contact member, a force in the insertion direction of the connection pin acts on the contact member due to friction between the elastic socket and the connection pin. Is supported by the stopper means. Therefore, the force acting on the contact member does not act on the portion where the end of the lead portion is connected to the electric circuit member via the lead portion extending from the elastic socket portion of the contact member. Separation of the connection portion is prevented beforehand.

Therefore, a connector is obtained which can improve the reliability of the connection between the end of the lead portion extending from the elastic socket portion of the contact member and the electric circuit member.

According to the second aspect of the present invention, the stopper means includes a cut-and-raised tongue provided on the elastic socket portion of the contact member, and an engaging step portion with which the tongue engages. Therefore, the stopper means can be formed without providing a separate body.

According to the third aspect of the present invention, since a flexible portion is formed in the lead portion of the contact member, there is a slight play (a play gap) in the stopper means, or there is no connection pin. When the force acting on the elastic socket portion at the time of insertion exceeds the supporting ability of the stopper means, the force acting on the elastic socket portion or a part of the force is absorbed and supported by the flexible portion being bent, The force acting on the connection between the end of the lead and the electric circuit member can be reduced as much as possible.

The contact member 2 accommodated in the connector case 1 is made of a conductive elastic material. The contact member 2 includes an elastic socket portion 6 into which a connecting pin described later is inserted and a lead portion 7 extending from the elastic socket portion 6. Have.

The elastic socket portion 6 of the contact member 2 is formed by bending a flat flat side wall 8 and a tip of an upright piece 9 formed by bending both sides of the flat side wall 8 at substantially right angles so as to approach each other. It has a curved side wall 10 and is formed in a substantially rectangular shape as a whole. The flat side wall 8 is formed with a projection 11 swelling toward the curved side wall 10, and the curved side wall 10 is formed with a slit 12 at a substantially central position in the axial direction thereof. The connection pins described later are inserted between the flat side walls 8 and the curved side walls 10 to make elastic contact.

The flat side wall 8 of the elastic socket portion 6
Is formed with a tongue 13 cut and raised toward the inner peripheral side of the connector case 1 and is engaged with the engaging step 5 of the connector case 1. The stopper means 3 is formed by the joint portion 5. That is, the tip of the tongue piece 13 is engaged with the engaging step 5 of the connector case 1 with the tip thereof facing the lead portion 7.
Thus, the stopper means 3 supports a force acting on the elastic socket portion 6 when a connecting pin described later is inserted. Conversely, when the contact member 2 is accommodated in the connector case 1, the contact member 2 is inserted into the connector case 1 from the elastic socket portion 6, so that the tongue piece 13 becomes As a result, the stopper means 3 does not cause any inconvenience to the accommodating operation of the contact member 2 because the stopper member 3 is pushed back to the position before cutting and raising.

The lead portion 7 of the contact member 2 is formed with a flexible portion 14 which is curved at a substantially central portion, and the end 7a of the lead portion 7 is soldered to the electric circuit member 15 by soldering or welding. It is connected.

Next, referring to FIGS. 3 and 4, the connection pin 1 inserted into the elastic socket portion 6 of the contact member 2 will be described.

In such a configuration, the connection terminal 18
The connection pin 17 is inserted into the elastic socket portion 6 of the contact member 2 in the axial direction, and the connection pin 17 resiliently contacts the elastic socket portion 6 to establish an electrical connection therebetween. Specifically, the connection pin 17 is inserted between the flat side wall 8 and the curved side wall 10 of the elastic socket portion 6, and the connection pin 17 comes into contact with the projection 11 formed on the flat side wall 8 and resiliently contacts the curved side wall 10. , And mutual electrical connection is achieved. In this case, the guide piece 22 formed on the holding member 21 of the connection terminal 18 is located on the outer peripheral side of the connector case 1 and guides the connection of the connection pin 17 to the elastic socket portion 6.

Here, when the connection pin 17 is inserted into the elastic socket portion 6, the elastic socket portion 6 and the connection pin 17
Although the force in the insertion direction of the connection pin 16 acts on the contact member 2 due to the friction with the contact member 2, the axial force acting on the contact member 2 is supported by the stopper means 3. That is, the tip of the tongue piece 13 of the stopper means 3 is engaged with the engagement step 5 of the connector case 1 with the tip directed toward the lead portion 7, so that when the connection pin 17 is inserted, The acting force will be supported. For this reason,
When the connection pin 17 is inserted, the force acting on the contact member 2 is connected to the electric circuit member 15 via the lead portion 7 extending from the elastic socket portion 6 of the contact member 2. It does not act on the connected portion, and separation of this connected portion, for example, the portion connected by soldering, welding, or the like, is prevented.

When the acting force exceeds the supporting ability of the stopper means 3, the force acting on the elastic member 2 or a part of the force is absorbed and supported by the flexible portion 14 being bent, so that the lead portion 7 is supported. The force acting on the connection between the end 7a and the electric circuit member 15 can be reduced as much as possible.

Although the embodiment has been described with reference to the drawings, the specific configuration is not limited to this embodiment, and can be changed without departing from the spirit of the invention.
For example, the shape of the elastic socket portion 6 is not limited to the shape having the curved side wall 10 but may be various shapes such as a cylindrical shape and a shape having a parallel blade receiving piece.
