Description

The present invention relates to a connector structure.

Conventionally, a twisted pair cable in which a plurality of electric wires are twisted together is less likely to be affected by noise than a mere parallel wire and emits less noise, so that it is preferably used for an in-vehicle network or the like. As the twisted pair cable, an STP (shielded twisted pair) cable and a UTP (unshielded twisted pair) cable are known. Of these, the STP cable is surrounded by a shield conductor around the electric wire and has a stronger resistance to noise.

For example, in Patent Document 1, an inner conductor terminal connected to an end portion of an STP cable, an inner housing (dielectric) that accommodates the inner conductor terminal, and a shield conductor of the STP cable are connected to surround the inner housing. A connector including a shield shell and an outer housing that houses the shield shell is disclosed.

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

The connectors of Patent Documents 1 and 2 include a common configuration in which each electric wire of a UTP cable and an STP cable is connected to a terminal and each terminal is housed in a dielectric. In this case, if the STP cable is replaced with the UTP cable or the UTP cable is replaced with the STP cable by utilizing the common structural part in each connector, the mold design becomes easy. The cost can be reduced. However, there is a circumstance that the UTP cable and the STP cable are not compatible in principle, and their impedances are different.

The present invention has been completed based on the above circumstances, and an object thereof is to provide a connector structure having excellent versatility .

The connector structure of the present invention is a connector structure that selectively uses either a UTP connector or an STP connector, wherein the UTP connector has a box portion into which a male terminal is inserted and connected, and is connected to each electric wire of a UTP cable. A UTP connecting terminal, a UTP dielectric having an accommodating portion for accommodating the UTP connecting terminal, and a UTP housing holding the UTP dielectric, and a male terminal is inserted and connected to the STP connector. An STP connection terminal that has a box portion and is connected to each electric wire of an STP cable, an STP dielectric body that has a storage section that stores the STP connection terminal, and an STP housing that holds the STP dielectric body. The STP connection terminal and the UTP connection terminal have substantially the same shape, the UTP housing and the STP housing have substantially the same shape, and each of the UTP dielectric and the STP dielectric is Are arranged in pairs in the width direction orthogonal to the insertion direction of the male terminal via a partition wall, and the thickness of the partition wall of the UTP dielectric is the thickness of the partition wall of the STP dielectric. A receiving portion and an elastic contact piece facing the receiving portion are arranged in the box portion of each of the UTP connection terminal and the STP connection terminal, the receiving portion and the elastic contact piece being thinner. The insertion area of the male terminal between the insertion areas of the UTP connection terminal is eccentric to the outside in the width direction of the accommodation portion, the insertion area of the STP connection terminal is in the width direction of the accommodation portion. It is characterized by being eccentric inward.

The partition wall of the UTP dielectric is thinner than the partition wall of the STP dielectric. Therefore, when the UTP connection terminals connected to the respective electric wires of the UTP cable are housed in the housing portions forming the pair of UTP dielectrics, the impedance can be reduced. On the other hand, if the STP connection terminals connected to the respective wires of the STP cable are accommodated in the accommodating portions forming the pair of STP dielectrics, the impedance can be increased. Thereby, the impedance can be appropriately adjusted between the UTP cable side and the STP cable side.
The UTP connection terminal and the STP connection terminal have substantially the same shape, and the UTP housing and the STP housing have substantially the same shape. Moreover, since the insertion area of the UTP connection terminal is eccentric to the outer side in the width direction of the accommodating portion and the insertion area of the STP connection terminal is eccentric to the inner side in the width direction of the accommodating portion, the STP and the male terminal to be connected with the UTP connection terminal are eccentric. The distances (pitch widths) in the width direction of the male terminals that are connection partners of the connection terminals can be made uniform to the same pitch width. Therefore, it is not necessary to make a large structural change as a whole, and the UTP cable and the STP cable can be easily replaced.

It is equal to the pitch width of the accommodating portion minus the pitch width of the accommodating portion forming the pair of UTP dielectrics. According to this, it is possible to cancel the difference in pitch width between the accommodating portions by only changing the positional relationship between the elastic contact piece and the receiving portion between the UTP connection terminal and the STP connection terminal.

The tab portion 92 is inserted and connected to the box portion 27 of each STP connection terminal 21B (see FIG. 25). Further, the outer conductor 24B is connected to the ground plate 68 installed on the hood portion 94.

[Effect]
In the case of the first embodiment, the pitch width of the accommodating portion 26 forming the pair of the UTP dielectrics 22A is made smaller than the pitch width of the accommodating portion 26 forming the pair of the STP dielectrics 22B, and the accommodating portions forming the pair of the UTP dielectrics 22A. The distance between the facing surfaces of the box portion 27 of the UTP connection terminal 21A housed in the portion 26 is smaller than the distance between the facing surfaces of the box portion 27 of the STP connection terminals 21B housed in the housing portion 26 forming a pair of the STP dielectric 22B. It has been shortened. Therefore, the impedance on the UTP cable 10A side can be reduced and the impedance on the STP cable 10B side can be increased, and the impedance can be appropriately adjusted between the UTP cable 10A side and the STP cable 10B side. As a result, it becomes possible to easily change the specifications between the UTP connector 20A and the STP connector 20B.

Further, the UTP connection terminal 21A is arranged in each accommodation portion 26 of the UTP dielectric 22A in a state of being aligned with the elastic contact piece 32 inward in the width direction, and the STP connection terminal 21B is disposed in each accommodation portion 26 of the STP dielectric 22B. Are arranged in a back-to-back state with the elastic contact piece 32 facing outward, so that the insertion area 53 of the UTP connection terminal 21A is eccentric to the outside in the width direction of the housing portion 26, and the insertion area 53 of the STP connection terminal 21B is located in the housing portion. It is eccentrically arranged inside 26 in the width direction. The amount of eccentricity in which the insertion region 53 of the UTP connection terminal 21A is eccentric to the outside in the width direction is equal to the amount of eccentricity in which the insertion region 53 of the STP connection terminal 21B is eccentric to the inside in the width direction, and the accommodating portions 26 forming a pair with the STP dielectric 22B. Is substantially equal to the value obtained by subtracting the pitch width of the accommodating portions 26 forming the pair of UTP dielectrics 22A from the pitch width.

Therefore, only by changing the positional relationship between the elastic contact piece 32 and the receiving portion 31 between the UTP connection terminal 21A and the STP connection terminal 21B, the difference in pitch width between the accommodating portions 26 is offset, and the male terminal 91. The pitch width between the tab portions 92 of the mating UTP connector 90A and the mating STP connector 90B can be made the same, and the mating UTP connector 90A and the mating STP connector 90B can have the same pitch width. Can be structured. Specifically, the mating UTP connector 90A and the mating STP connector 90B include a hood portion 94 including an outer cylindrical portion to which the peg 95 is attached and an inner back wall portion to which the male terminal 91 is attached. Of these, since the outer tubular portion has a common structure between the mating UTP connector 90A and the mating STP connector 90B, the mating UTP connector 90A and the mating UTP connector 90A are replaced by replacing the inner back wall portion. It is possible to meet the respective specifications of the side STP connector 90B. As a result, it is possible to realize a connector structure having excellent versatility as a whole.

Further, the respective box portions 27 of the respective UTP connection terminals 21A and the respective STP connection terminals 21B have the same shape, the UTP housing 23A and the STP housing 23B also have the same shape, and further, the UTP dielectric 22A and the STP dielectric. Since 22B is also similar, the STP cable 10B and the UTP cable 10A can be replaced without making a large structural change as a whole, and the cost can be reduced.
