INVENTION The present invention relates to a different party contact
A connector for connection to the connection portion, specifically in combination superimposed plurality of <br/> module including a plurality of contacts are incorporated into <br/> insulator within the housing
About the storage was co-next-data.

[0002]

2. Description of the Related Art Conventionally, there is a connector of this type disclosed in, for example, Japanese Patent Application Laid-Open No. 3-233879.
In this connector, only a portion of the plurality of contacts connecting the contact portion and the board connection portion is covered with the insulator constituting the module, and the contact portions of the contacts are exposed.

[0003]

In the case of the above-mentioned connector, since the contact portion of each contact is exposed from the insulator, the contact may be touched by hand when assembling or connecting with the mating connector. Alternatively, the contact often deforms due to collision with other parts other than the connection part of the mating connector. In particular, when the contact has a cantilever shape, the contact portion is easily deformed.

[0004] When the contact portion of the contact in this manner is deformed, since it becomes impossible to make a connection with a mating side connector, it is necessary to work to correct the deformation of the contacts in such a case. However, when the contact portion is excessively deformed and cannot be corrected, the contact once loaded on the insulator must be removed and a new contact must be loaded. Typically, the contacts are molded in and will be discarded if they cannot be reloaded.

Further, if the contact portion of the contact is exposed to the outside, it is easy for the hand to touch during connection or assembly work, and dirt is easily attached to the contact portion. If the contact portion is soiled in this way, it may cause a contact failure, so that it takes time to clean the waste.

Further, separately performing such a repairing operation and a cleaning operation not only causes the manufacturing process to be complicated, but also increases the yield if the disposal of defective products increases, resulting in a reduction in cost. It leads to up.

The present invention has been made to solve such a problem, and a technical problem of the present invention is to provide a connector in which a contact portion of a contact is hardly deformed, and a dirt is hardly attached to the contact portion. .
