A socket-side terminal includes: a root section that is fixed to a conductive wiring pattern on the main surface of a circuit wiring substrate by using solder; a rising section rising up from the root section and spaced apart from the main surface; an inverted U-shaped section one end of which is continuous with the top end of the rising section; a falling section that extends from the other end of the inverted U-shaped section towards the main surface; an inclined section that, as the inclined section extends from the bottom end of the falling section towards the main surface, is inclined with respect to the main surface to be spaced apart from the rising section; and an opposing section that is continuous with the bottom end of the inclined section, is positioned so as to be opposing the falling section, and is in contact with a header-side terminal.

The metal terminals are a first terminal, and a second terminal mated with the first terminal, the first terminal has a first main body portion, a first contact portion, and a first lock portion, the second terminal has a second main body portion, a second contact portion contacting the first contact portion, and a second lock portion locking the first lock portion. The first lock portion includes a first engaging portion arranged on a surface of the first main body portion, and the second lock portion including a pair of second engaging portions arranged on opposing surfaces of the second main body portions.

An electrical connector includes an insulative housing, a plurality of contacts retained in the insulative housing and a fastener. The insulative housing has a rear surface. Each contact has a connecting leg extending beyond the rear surface. The connecting legs are arranged in at least a row, and each connecting leg has a connecting portion and a resisting portion. The fastener has at least a contact receiving chamber, a flexible circuit board receiving chamber communicating with the contact receiving chamber and a press section. The contact receiving chamber is arranged between from the flexible circuit board receiving chamber and the press section. Wherein the fastener has a fixed position on the insulative housing, and as moving the fastener to the fixed position, the press section presses the resisting portion to drive the connecting portion projecting into the flexible circuit board receiving chamber.

A connector includes a rectangular flat-plate housing including a first positioning hole and a second positioning hole, and a contact row and a contact row held on the housing. The housing includes a first pitch side surface and a second pitch side surface on an opposite side of the first pitch side surface. The contact row and the contact row extend from the first pitch side surface to the second pitch side surface. The first positioning hole is disposed between the first pitch side surface and the contact row, and the second positioning hole is disposed between the first pitch side surface and the contact row.

A wire connection terminal structure includes a leaf spring, a conductive plate and a fixing frame framing and connecting with the leaf spring and the conductive plate. The conductive plate is formed with a base section assembled with the fixing frame. The leaf spring is formed with an elastic swingable holding section extending to a position in contact with the base section. The holding section and the base section define therebetween an elastic holding mouth. An external electrical wire can be plugged into the holding mouth and held between the holding section and the base section and electrically connected with the conductive plate. The conductive plate and the fixing frame are two separate components so that the conductive plate is solely made of a high-conductivity material, while the fixing frame is made of a material with higher structural rigidity.

Connection reliability of terminals in a movable connector is enhanced. The movable connector includes a fixed housing having an abutment receiving portion and a movable housing having an abutment portion. When a pin terminal is fitted and inserted, the abutment portion abuts on the abutment receiving portion. This prevents arcuate curved deformation of the movable housing, and restricts a movable piece of a terminal at a center portion of the movable housing from being slightly stretched from the beginning of fitting and from constantly receiving load.

The connector is provided with a locking mechanism capable of engaging and disengaging with each other a receptacle and a plug. The receptacle is provided with a first housing and a first contact. The plug is provided with a second housing and a second contact. The first housing has at a recess portion a lock arm provided at its end with a hook portion. The second housing has at a header portion an engaging protrusion. When the header portion is inserted into the recess portion, the engaging protrusion rides over the hook portion, and the complete fitting of the receptacle and the plug can be felt. When the header portion is pulled out from the recess portion, the hook portion is displaced, and the plug can be readily pulled out from the receptacle.

A plug connector of the present disclosure includes a plug housing and a plurality of plug terminals stored in the plug housing. This plug connector is fitted in a receptacle connector having a receptacle terminal, and is connected to a cable having a sheet shape and including a cable terminal, thereby establishing electrical connection between the receptacle terminal and the cable terminal. Each of the plug terminals has a contact section and a connection section. The contact section is contactable with the receptacle terminal, and the connection section is connectable to the cable terminal. In a state in which the plug connector is fitted in the receptacle connector, the connection section is disposed such that the connection section is exposed from the plug housing.

An electrical connector includes an insulative housing, a plurality of contacts retained in the insulative housing, a fastener and a first sealing ring. The insulative housing has a rear section extending backwardly. The rear section has a rear space and a first peripheral wall around the rear space. Each contact has a connecting leg extending into the rear space. The fastener has a mating section to engage with the rear section and a board receiving chamber extending therethrough along a front to back direction. The fastener has a fixed position on the insulative housing, and as moving the fastener to the fixed position, the connecting legs are pressed into the board receiving chamber for electrically connecting with the flexible printed circuit board, and the first sealing ring is sealed around the junction of the contacts and the flexible printed circuit board.

An electrical connector includes an insulative housing; plural contacts secured to the insulative housing, and a pair of holding members insert molded with the insulative housing, the holding member including a base, a pair of arms extending from the base, and a pair of contact portions bent inwardly from the arms, wherein the base is embedded in the insulative housing. Also an electrical connector includes an insulative housing, plural contacts secured to the insulative housing, and a pair of holding members insert molded with the insulative housing, each holding member including a base, a pair of arms extending from the base, and a head bent inwardly from the base, wherein the base is embedded in the insulative housing.
