Description

  The present invention relates to a connector structure.

  BACKGROUND ART Conventionally, a twisted pair cable in which a plurality of electric wires are twisted is less susceptible to noise than a simple parallel line and less in noise radiation, and thus, it is suitably used for an on-vehicle network or the like. Known twisted pair cables are STP (shielded twisted pair) cable and UTP (unshielded twisted pair) cable. Among them, the STP cable is surrounded by the shield conductor around the wire, and is more resistant to noise.

  For example, according to Patent Document 1, an inner conductor terminal connected to an end portion of an STP cable, an inner housing (dielectric) accommodating the inner conductor terminal, and a shield conductor of the STP cable are surrounded to surround the inner housing. A connector is disclosed that includes a shield shell and an outer housing that receives the shield shell.

  On the other hand, Patent Document 2 discloses a connector including a connection terminal connected to an end of a UTP cable, and a connector main body (dielectric) having a terminal accommodating portion for accommodating the connection terminal.

[Function effect]
UTP dielectric 22A and STP dielectric 22B are made of the same material except for partitions 43A and 43B, and partition 43A of UTP dielectric 22A is made of a material having a relatively high dielectric constant, and partition of STP dielectric 22B Since 43B is made of a material having a relatively low dielectric constant, the pitch between the terminals of the UTP dielectric 22A, the STP dielectric 22B, the UTP housing 23A, the STP housing 23B, the mating UTP connector, and the mating STP connector is changed Even without the impedance, the impedance can be appropriately adjusted, and the specification change between the UTP connector 20A and the STP connector 20B can be easily performed.

  In particular, since the UTP connection terminal 21A and the STP connection terminal 21B have substantially the same shape and the UTP housing 23A and the STP housing 23B have substantially the same shape, when manufacturing them, There is no need to prepare a plurality of molds, and the cost can be significantly reduced.

Other Embodiments
Another embodiment will be briefly described.
(1) In the first embodiment, only partition walls are made of different materials, but in the case of the present invention, the entire UTP dielectric is made of a material having a relatively high dielectric constant, and the entire STP dielectric is relative. It may be made of a material having a low dielectric constant. In addition, the upper dielectric of UTP dielectric (dielectric having a partition) is made of a material having a relatively high dielectric constant, and the upper dielectric of STP dielectric (dielectric having a partition) has a relative dielectric constant. It may be composed of a low material.
(2) In Example 1, although the partition was provided in the main-body part so that attachment or detachment was possible, in the case of this invention, the partition may be integrally provided in the main-body part.
(3) In the first embodiment, both the UTP dielectric and the STP dielectric are vertically dividable, but in the case of the present invention, at least one of the UTP dielectric and the STP dielectric is integrally provided indivisiblely. It may be done. The partition wall may be attached to the integrated dielectric by sliding from behind.
(4) In the first embodiment, the outer conductor of the STP connector is vertically dividable, but in the case of the present invention, the outer conductor may be integrally provided indivisiblely.
