Problems solved by technology

However, if the miniaturization of the connector is realized by simply shortening the above-mentioned connection portion, the area of ​​the solderable portion of the connection portion will be reduced, and there is fear that the electrical conduction between the connector and the circuit board will become unstable, and Concerned about the decrease in the fixing strength of the connector to the circuit board

Abstract

The present invention provides an electric connector used for a circuit substrate, capable of downsizing a connector in an opposite direction of sidewalls of a casing without shortening a connecting part. The electric connector used for the circuit substrate comprises a casing having two sidewalls and a plurality of terminals arranged and maintained at the sidewalls; wherein, a containing recess is formed between the sidewalls of the casing; the terminal comprises an inner side foot part which is maintained at the sidewall and extended along a vertical direction at a position of the containing recess side, an outer side foot part which is extended along the vertical direction at a position nearer to an outer side than the inner side foot part, a joint part which joints with an upper end of the inner side foot part and an upper end of the outer side foot part, and a connecting part which is extended towards the outer side from a lower end of the outer side foot part, wherein, the outer side foot part is configured in the way that the lower end of the outer side foot part is arranged at a position nearer to an inner side than an upper end thereof, a part of the connecting part is arranged within a range repeated with the outer side foot part in the opposite direction.

Description

technical field [0001] The invention relates to an electrical connector for a circuit substrate. Background technique [0002] As an electrical connector for a circuit board that is arranged on a circuit board and holds a plurality of terminals in a row on paired side walls of a housing, for example, a connector disclosed in Patent Document 1 is known. The connector of this patent document 1 has: a case having a substantially cubic shape, and a target connector can be accommodated in a storage space surrounded by a peripheral wall from above; and a plurality of terminals arranged and held in the case. Two side walls extending along the longitudinal direction of the housing in a mutually opposing manner among the peripheral walls of the housing. [0003] The terminal of the connector in this Patent Document 1 has an inverted U-shaped portion, and the inverted U-shaped portion is held by being press-fitted toward the side wall of the housing from below or integrally formed wi...
