Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a connector used in, for example, a computer.

(Prior Art) Conventionally, a plurality of contacts are each pressed into contact with a plurality of contacts by fitting the contacts into the predetermined spacing of a connector which is fitted into a connector main body so as to face each other with a predetermined spacing therebetween. A connector in which two contacts are fitted back to back into a connector body in two rows is known.

This connector may not use all of the two rows of contacts depending on its purpose.

Therefore, the manufacturer supplies the connector main body and the contact separately to the user, and the user connects the electric wire to the terminal portion of the contact by crimping, and then fits the contact into the connector main body for use.

(Problem to be Solved by the Invention) However, a connector in which all or an appropriate number of the contacts in one row of the two rows of contacts are not attached to the connector body is arranged so that they are placed facing each other at a predetermined interval in the connector body. When the connector is fitted into the predetermined interval of another connector in which a plurality of contacts are fitted into each connector, the contact pressure between the plurality of contacts in the other row and the plurality of contacts of the other connector causes the connector to There was a problem in that the connector main body moved to one side of the predetermined distance and its contact pressure decreased, causing an imbalance in the contact pressure of all contacts.

The present invention aims to solve these conventional problems.

(Means for Solving the Problems) The present invention provides a connector that is fitted into a connector main body such that a plurality of contacts face each other at a predetermined interval, and is fitted into the connector main body at a predetermined interval. In a connector in which a plurality of contacts are fitted into the connector body in two rows back to back, each of which press-contacts a contact, and an electric wire is connected to the terminal part of the contact by crimping, all of the contacts in one row Alternatively, insulating dummy contacts are fitted into the connector body instead of an appropriate number of contacts.

(Example) Embodiments of the present invention will be described with reference to the drawings.

In the drawings, A is the original connector, B is another connector in which a plurality of contacts C are fitted into the connector body a so as to face each other with a predetermined interval b, and the original connector A is a connector of the other connector B. It is connected to another connector B by fitting into the predetermined interval b.

The connector body 1 of the proposed connector A consists of a fitting part 1A into another connector B and a base part 1B,
Made of insulating material. A large number of grooves 3, for example 18 grooves, are formed on both sides of the fitting portion 1A so that the contacts 2 are fitted back to back. The base portion 1B is formed with two rows of through holes 4 that are connected to the grooves 3 and into which the contacts 2 are fitted.

The contact 2 is engaged with an elastic contact piece 5 that contacts a contact C of another connector B, a step 6 formed at the bottom of the groove 3 of the connector body 1, and a step 7 formed in the through hole 4, respectively. and contact 2
a locking tongue piece 8 and a locking protrusion 9 for fixing the connector body 1 in a predetermined position on the connector body 1; a pair of wire pressure welding pieces 11, 11 and a pair of wire locking pieces 12 formed on the terminal portion 10; 12.

In the figure, 13 is a dummy contact made of an insulating material such as 66 nylon, and the dummy contact 13 has approximately the same size as the contact 2, and like the contact 2, when fitted into the groove 3 and the through hole 4. A locking tongue piece 1 that locks onto the stepped portions 6 and 7 to fix the dummy contact 12 in a predetermined position.
4 and a locking step portion 15.

In the illustrated example, contacts 2 are fitted into all, for example, 18 grooves 3 formed on one side of the fitting portion 1A of the connector main body 1, and contacts 2 are fitted into all, for example, 18 grooves 3 formed on the other side. A dummy contact 13 is fitted instead.

Thus contact 2 and dummy contact 13
When the connector A that has been fitted into the connector body 1 is inserted into another connector B at a predetermined interval b, and the contacts 2 are brought into contact with the contacts C of the other connector B, one side of the fitting part 1A of the connector body 1 Since the dummy contacts 12 are fitted in the contact mounting positions, the contact pressure between the contacts 2 and the contacts C can maintain the same value as when all the contacts 2 are mounted.

(Effect of the invention) As described above, according to the invention, in a connector in which a plurality of contacts are fitted in two rows back to back on the connector body, all or an appropriate number of the contacts in one row are not used. Even in such a case, the contact pressure between the contacts and the contacts of other connectors does not decrease, and the contact pressures of all the contacts do not become unbalanced.

Claims (1)

[Scope of utility model registration request] A plurality of contacts are fitted into the connector body so that the plurality of contacts face each other at a predetermined interval, and a plurality of contacts are fitted into the predetermined spacing of the connector so as to be in pressure contact with the plurality of contacts, respectively. In a connector that is fitted in two rows back to back, and in which electric wires are connected to the terminal portions of the contacts by crimping, insulating dummy contacts may be used in place of all or an appropriate number of contacts in one row. A connector characterized by being fitted into a connector body.
