Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a twisted pair connector, and more particularly, to a twisted pair connector capable of effectively preventing a reduction in the noise resistance of the twisted pair wire after the twisted pair wire is connected.

[0002]

2. Description of the Related Art In electronic equipment and measuring equipment, a twisted pair wire having a structure in which a pair of insulated conductors are twisted is used to prevent disturbance of a transmission signal due to noise or the like.

FIG. 5 shows a conventional example of a socket connector used for connecting this kind of twisted pair wire to a substrate or the like. The socket connector 21 includes a socket contact 22 connected to a twisted pair wire 23, and a housing in which a large number of through holes 21a for inserting the socket contact 22 are formed in a horizontal direction or a vertical direction. .

When the twisted pair wire 23 is connected to the socket connector 21, the following method is generally adopted. That is, first, the twist at the connector side portion of the twisted pair wire 23 is loosened. Next, the socket contacts 22 are fixedly connected to the connector-side ends of the pair of insulated conductors 23a, 23a constituting the twisted pair by soldering or crimping. Thereafter, a procedure is adopted in which the connector side end is twisted again, and the socket contacts 22, 22 are inserted into the corresponding insertion holes 21a of the socket connector 21, respectively. Although the above is an example of a socket connector, it goes without saying that the same applies to a pin connector.

[0005]

However, in the case of the conventional connector, it is difficult to twist the insulated wire after the contact connection, so that the noise resistance of the twisted pair wire is impaired. There is a problem.

For this reason, it is conceivable to carry out the work by shortening the loosened portion of the connection portion. However, the shorter the loosened portion, the more difficult and troublesome the wire connection work, and the workability is reduced.

Therefore, an object of the present invention is to provide a twisted pair wire connector which can easily perform a connection operation with a twisted pair wire without deteriorating noise resistance.

[0008]

According to the present invention, there is provided a first housing forming a connector outer shell, a second housing formed separately from the first housing and mounted and held in the first housing. A twisted pair connector characterized by including a contact held by the second housing and independently connected for each pair of twisted pair wires.

[0009]

According to the above construction, the second housing is appropriately rotated after the contact connection, and the second housing is mounted and held on the first housing, so that the twist processing can be easily and surely performed on the twisted pair wire. Will be able to As a result, the noise resistance of the twisted pair wire is not impaired, and the connection work becomes very easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pin connector A as an embodiment of the present invention shown in FIG. 1 includes a first housing 1, a second housing 3, and a pair of through holes 3 formed in the second housing 3.
b, 3b. The first housing 1 has a second housing attached thereto.
A plurality of lock mechanisms 2 for fixing and holding the housing 3 are provided. In the vicinity of the lock mechanism 2, partition walls 1c each having an engagement groove 1a into which an engagement protrusion 3a formed on a side surface of the second housing 3 is inserted are formed.

The procedure for connecting the twisted pair wire 5 to the pin connector A will be described below. That is, after the twist of the connector side portion of the twisted pair wire 5 is loosened, the exposed conductor at the end is connected to the corresponding pin contact 4 by soldering or crimping, respectively.

Next, as shown in FIG. 2A, the pin contacts 4 are inserted and fixed in the corresponding through holes 3b of the second housing 3, respectively. After that, the second housing 3 is rotated with the twisted pair wire 5 by an appropriate angle or number of times in the twisting direction I of the twisted pair wire 5 as shown in FIG. , Second
The housing 3 is mounted at a corresponding place of the first housing 1, that is, between the partition walls 1c. As a result, the second housing 3 is held by the first housing 1 by the lock mechanism 2. By carrying out the above construction sequentially or in parallel for each twisted pair wire, a plurality of second
The housings are respectively fixedly held.

FIG. 3 shows a pin connector A constructed as described above and a socket connector B constructed similarly.
FIG. In the figure, the first pin connector A
The connecting projection 4a of the pin connector 4 is provided through a through hole 1b formed in the housing 1, and the socket connector B is provided with a connecting recess of the socket connector 10 through a through hole 11b formed in the first housing 11. 10a face each other. FIG. 4 is a diagram when the pin connector A and the socket connector B are viewed from respective mating surfaces.

[0014]

[Effects of the Invention] As described above, according to the twisted pair wire connector of the present invention, the twist of the twisted pair wire can be recovered by a simple operation even after the contacts are connected, and therefore, the connection work with the twisted pair wire can be reduced. , And can be easily performed without deteriorating the noise resistance of the twisted pair wire.
