Description

  The present invention relates to a high density connector in which a plurality of two-point contact type contact members are arranged in parallel in a body.

  The jack side of the high-density connector is formed by arranging a plurality of two-point contact type contact members in parallel in an insulating casing. The two-point contact type contact member is a base formed in a substantially U-shape. The elastic contact plates that are extended in a cantilevered manner from one side edge of the opposing wall are formed so as to be close to each other, and the portion close to the tip of the extended elastic contact plate is formed in the contact portion Then, using the spring elasticity of the elastic contact plate, an electrical connection is obtained by elastically holding the plug-side terminal inserted between the two elastic contact plates.

  The conventional two-point contact type contact member is, for example, as shown in the drawing of Patent Document 1, from one end surface of a wall surface facing a base (connecting piece) formed in a U-shape. The elastic contact plate is formed so as to be inclined toward each other, and the connecting wall portion connecting the opposing wall surfaces connecting the elastic contact plates at the U-shaped base is opposite to the elastic contact plate lead-out direction. The terminal board was formed in a shape that continued from the end face portion.

Japanese Patent No. 2887999

  The conventional two-point contact type contact member described above has a problem that transmission characteristics deteriorate because the base portion formed in a U-shape is long. It is also conceivable to make the elastic contact plate longer by shortening the base formed in the U-shape, but in this case, the surface area of the opposing surface of the elastic contact plate is large and the capacitance increases. As a result, the impedance becomes too low, the transmission characteristics are poor, and it is not suitable for high-speed signals.

  This invention is made paying attention to such a point, and it aims at providing a connector with a high-speed transmission characteristic.

In order to achieve the above object, according to the first aspect of the present invention, a pair of elastic contact plates disposed in opposition to each other, and the pair of elastic contact plates are continuously provided from one end face of the opposing wall surface. A two-point contact type contact having a U-shaped connecting portion and a terminal plate extending from the other end surface of the U-shaped connecting portion, and a plurality of contacts arranged in parallel in the connector body,
The length of the elastic contact plate extending from the U-shaped connecting portion is set longer than the length of the U-shaped connecting portion, and the terminal plate is extended in a state where it is positioned on the extension line of one elastic contact plate. It is said.

  The invention described in claim 2 is characterized in that, in addition to the configuration described in claim 1, a slit is provided in the connecting wall portion connecting the opposing wall surfaces of the U-shaped connecting portion at each contact.

  Furthermore, in addition to the structure described in claim 1 or 2, the invention described in claim 3 is formed by forming a slit groove along the longitudinal direction of the elastic contact plate of the contact, and forming the slit groove. The contacts having contact plates are arranged in a plurality of stages in a plurality of rows in the connector body with their terminal plates facing each other.

  According to a fourth aspect of the present invention, in addition to the configuration described in any one of the first to third aspects, the arm length between the contact position formed on the elastic contact plate and the inclined continuous base portion Is different in unit contact plates constituting a pair of elastic contact plates.

  According to the first aspect of the present invention, in a two-point contact type contact having a U-shaped connecting portion and a pair of elastic contact plates extending from the opposing wall surface, the elastic contact plate extending from the U-shaped connecting portion. When the length of is set to be longer than the length of the U-shaped connecting part and the terminal plate is placed in a state where it is located on the extension line of one elastic contact plate, multiple contacts are arranged in parallel in the connector body. In addition, since the side surfaces of the adjacent connectors face each other, the surface area of the facing surfaces is reduced, the capacitance is kept small, and the impedance is not reduced too much. Thereby, the transmission characteristic is good and it is possible to cope with a high-speed signal.

  When the slit is provided in the connecting wall portion of the U-shaped connecting portion as in the invention described in claim 2, the surface area at the connecting portion is also reduced, and the impedance is stabilized. As a result, it is possible to cope with a higher-speed signal than in the case where no slit is provided in the connecting wall portion.

  Further, as in the invention described in claim 3, a slit along the longitudinal direction is formed in the elastic contact plate of the contact, and the contact having the elastic contact plate in which the slit is formed is in a state where the terminal plates face each other. When the connector body is arranged in multiple rows and multiple rows, even if the contacts are arranged in multiple rows on the connector body and the elastic contact plates of the upper and lower contacts face each other, The effect is reduced and high-speed signals can be handled.

  Further, as in the invention described in claim 4, the arm length between the contact position formed on the elastic contact plate and the inclined continuous base is made different between the unit contact plates constituting the pair of elastic contact plates. In this case, since the length of the continuous arm from the inclined continuous base portion of the elastic contact plate to the contact point is different, it becomes strong against disconnection due to co-vibration.
