Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a connector for twisted pair wires, and more specifically, to twisted pair wire connectors. A twist that can effectively prevent the deterioration of the noise resistance performance of twisted pair wires after wiring. This invention relates to a connector for straight line.

0002

[Conventional technology]

Prevents disturbances in transmission signals due to noise etc. in electronic equipment and measuring equipment. In order to A wire is used.

0003 For example, a socket is used when connecting this type of twisted pair wire to a board, etc. An example of a conventional connector is shown in FIG. This socket connector 21 is a twisted pair The socket contact 22 connected to the wire 23 and this socket contact 22 A housing with a large number of through holes 21a formed horizontally or vertically for insertion. It is composed of

0004 When connecting the twisted pair wire 23 to the above socket connector 21, generally The following method is adopted. That is, first, at the connector side portion of the twisted pair wire 23, Loosen the strands. Next, a pair of insulated conductor wires 23a forming a twisted pair wire , 23a, respectively, solder the socket contacts 22, 22 to the connector side ends. Connect the wires by fixing them by crimping or caulking. Then this connector Twist the side ends again and connect the socket contacts 22, 22 to the socket connector 2. The procedure is to insert each into the corresponding insertion holes 21a of 1. By the way, that's all This is an example for a socket connector, but the same applies to a pin connector. Needless to say.

[0005]

[Problem that the idea aims to solve] However, in the case of conventional connectors, after contact connection, the insulated conductor Since it is difficult to twist the wire back to its original state, There is a problem that noise resistance performance is impaired.

[0006] For this reason, it is possible to shorten the loosened part of the connection part during construction, but The shorter the connecting part, the more difficult and troublesome the wiring work will be, which will reduce work efficiency. Put it away.

[0007] Therefore, the problem with this invention is that the connection work with twisted pair wires impairs noise resistance. To provide a twisted pair wire connector that can be easily and easily installed. There is a particular thing.

[0008]

[Means to solve the problem]

According to the present invention, a first housing forming a connector outer shell; a second housing that is made separately from the first housing and is held attached to the first housing; Contacts held in two housings and connected independently for each twisted pair of wires A twisted pair wire connector is obtained.

[0009]

[Effect]

With the above configuration, the second housing can be rotated appropriately after contact connection. By attaching this to the first housing and holding it, the twisted pair wire can be restored to its original state. The twisting process can be easily and reliably performed. As a result, The noise resistance performance of isto pair wire is not impaired, and wiring work is very easy. becomes.

【Example】

A pin connector A as an embodiment of the present invention shown in FIG. and a second housing 3, and a pair of through holes 3b, 3 formed in the second housing 3. It consists of a pair of pin contacts 4 that are inserted into b. In the first housing 1 , a plurality of locking mechanisms 2 for fixing and holding the second housing 3 attached thereto. We are prepared. Also, near this locking mechanism 2, there is a Partition walls 1c each having an engaging groove 1a into which the engaged protrusion 3a is inserted are formed. ing.

[0011] The procedure for connecting the twisted pair wire 5 to this pin connector A will be explained below. Immediately First, untwist the connector side part of the twisted pair wire 5, and then Connect each lead wire to the corresponding pin contact 4 by soldering or crimping. Connect.

0012 Next, as shown in Fig. 2(a), insert the pin contact 4 into the corresponding transparent part of the second housing 3. They are inserted and fixed into the holes 3b and 3b, respectively. After that, the second housing 3 is ) with the twisted pair wire 5 in the twisting direction I of the twisted pair wire 5. After returning the twisted pair wire 5 to its original twist by rotating it by an angle or number of times, 2 housing 3 is attached to the corresponding location of the first housing 1, that is, between the partition walls 1c. Ru. As a result, the second housing 3 is secured to the first housing 1 by the locking mechanism 2. held. The above work can be done sequentially or in parallel for each twisted pair wire. Thus, the plurality of second housings are each fixedly held on the first housing 1.

[0013] Figure 3 shows pin connector A configured as described above, and pin connector A configured in the same manner. FIG. 3 is a cross-sectional view of socket connector B. In the figure, for pin connector A, the first housing The connecting convex piece 4a of the pin connector 4 is inserted through the through hole 1b formed in the pin connector 1. In the socket connector B, through the through hole 11b formed in the first housing 11 The connection concave pieces 10a of the socket connector 10 face each other. Figure 4 shows this A diagram of pin connector A and socket connector B viewed from their respective mating surfaces. It is.

[0014]

[Effect of the idea]

As described above, according to the twisted pair wire connector of the present invention, the contacts can be wired. It is possible to restore the twist of twisted pair wires with simple work even after Therefore, the connection work with twisted pair wires can be done without impairing the noise resistance of the twisted pair wires. This makes it possible to perform this process easily and easily.
