A contactless inductive energy transmission device includes a primary and a secondary each having at least one coil. The coils are inductively coupled via an air gap. The primary and the secondary each also have a data transmission unit for the transmission of data via the air gap.

An electrical connector including an insulating body, a plurality of terminals, and at least one grounding member is provided. The terminals and the grounding member are disposed in the insulating body. At least one grounding terminal among the terminals and the grounding member next to the grounding terminal form an integrally-molded structure. A portion of the grounding terminal and a portion of the grounding member are misaligned from each other along an arrangement direction of the terminals.

A connector includes a body and a contact that is inserted into the body. The contact includes a protruding part that is protruded in a direction orthogonal to an insertion direction of the contact, a protrusion that is provided on an outer periphery of the contact, and an overhanging part that overhangs in the direction orthogonal to the insertion direction. The body includes, on an inner surface thereof, a guide groove that is fitted with the protruding part and is extended in the insertion direction, a housing part that has an internal dimension for press-fitting the contact, which includes the protrusion, thereto, and a press-fitting part that has an internal dimension for press-fitting the contact, which includes the overhanging part, thereto. An insertion distance A of the protruding part, an insertion distance B of the protrusion, and an insertion distance C of the overhanging part satisfy a relation A>B>C.

The circuit board includes a first contact portion electrically connected to the plurality of terminals, and a second contact portion, electrically connected to the connecting portion. The cover is fixed to the shell. The shell is arranged between the circuit board and the shell to fix the circuit board in the shell.

It is aimed to provide a circuit board connector and a circuit board connector manufacturing method capable of enabling molding by a small-size molding apparatus by performing insert molding in three stages. A circuit board connector (1) includes a case resin portion 2, a connector resin portion 3 having a base (31) and a tower (32) and connector terminals (6A, 6B and 6C). The connector resin portion (3) includes core resin portions (4A, 4B and 4C) for covering intermediate parts (63) of the connector terminals (6A, 6B and 6C) and an outer resin portion (5) for covering the core resin portions (4A, 4B and 4C). A resin material constituting the case resin portion (2) is joined to a resin material constituting the outer resin portion (5) by resin molding.

The present invention discloses a connector for a photovoltaic cell. The connector comprises a conductive portion and an insulating portion, wherein the conductive portion is wrapped with the insulating portion; the conductive portion is composed of a conductor and a cable line which are riveted with each other, and a retaining ring is arranged on the outer circumferential surface of the conductor; the insulating portion comprises a shell body, a basket-shaped fastener and a front sleeve; a first inner step surface and a second inner step surface are arranged in an inner cavity of the shell body; the front sleeve has an annular head part which sleeves the conductor; a first outer step surface is arranged at a tail part of the front sleeve, and props against the first inner step surface; the inner diameter of the head part of the front sleeve is larger than the outer diameter of the conductor and less than the outer diameter of the retaining ring. According to the connector disclosed by the present invention, the front sleeve for bearing a stress generated by the retaining ring during a forward extrusion process of the conductor is increased, such that the risks such as cracks originally appearing on the shell body and the like are transferred, and the service life of the whole connector is prolonged.
