  • Patent number: 7758355
    Abstract: In the case that a distance between contact portions and fixed portions of contacts of a connector is 2 mm or more, the contacts are each provided with an engaging portion in the proximity of the fixed portion, and the housing is provided in the inserting holes for the contacts with anchoring portions at locations corresponding to the engaging portions of the contacts so that the engaging portions of the contacts engage the anchoring portions of the housing, thereby preventing the contact portions of the contacts from being deformed and collapsed into a fitting opening by a connecting object, and preventing the contacts from buckling or being damaged and hence preventing any defective electrical connection.

  • Publication number: 20090130916
    Abstract: A connector to be mounted on a substrate includes a plurality of contacts each having a contact portion adapted to contact a mating object and a connection portion of a surface mounting type to be connected to a substrate, and a housing having inserting holes for arranging and holding the contacts therein and a fitting portion to be fitted with the mating object. The connection portions are arranged substantially in parallel with the bottom surface of the housing. The bottom surface of the housing is provided with protrusions respectively for the contacts for positioning the connection portions in directions of their heights and confirming positions of the connection portions in the longitudinal direction by bringing the individual connection portions into contact with the protrusions, respectively. The connector thus constructed is free from failed electrical connection and easily and visually confirmed whether the contacts are situated in correct positions without using jigs or the like.

  • Publication number: 20080299840
    Abstract: An L-shaped contact includes a contact portion adapted to contact a mating object, a fixed portion to be fixed to a housing, and a connection portion to be connected to a connecting object, and a hole formed in a bent portion between the fixed portion and the connection portion. When the contact is fixed to the housing, the contact is inserted into the housing by pushing an end face of the hole. The L-shaped contact ensures a stable contacting surface area for being pushed by a jig and enables to bear a heavy-electric current to pass therethrough without adversely affecting miniaturization of a connector and extremely narrow pitches of the conductors.
