The present invention relates to a structure of a connector connected to a balanced wire used for wiring of electronic devices such as a computer.

For electronic device wiring, so-called balanced wires in which a plurality of conductors are arranged in parallel and molded into an insulator in a tape form are used.

As a connector used for connection of this balanced wire and the printed circuit board of an apparatus, there exists a terminal part of a connector and a balanced wire as shown to FIG. 1, (a), (b), (c), for example. (a) is a perspective view showing a connector, (2) is a housing of a connector 1 having a wire insertion hole 3, and a plurality of spring-like contacts 4 are arranged in the wire insertion hole 3, The contactor 4 extends through the housing 2 as shown in (c) of the cross-section X-X 'shown in FIG. 1 (a) to form the foot 5 of the connector terminal. have. Reference numeral 10 denotes a contact partition provided on one inner wall surface of the housing.

The distal end 6 of the balanced wire inserted into the wire insertion hole 3 is one of those in which the insulator at the distal end of the balanced wire 7 is peeled off to expose the conductor 8, as shown in the perspective view in (b). A plastic plate 9 having a length equal to or longer than the length of the conductor 8 exposed to the surface is brought into close contact with each other. In general, a balanced wire having such a distal end 6 is commercially available.

In this case, the foot part 5 of the some terminal of the connector 1 is arrange | positioned as equal pitch A on the straight line of the width direction of the housing | casing 2, and this pitch A is a contactor of a connector ( It is equal to the pitch P of 4), ie, the conductor pitch B of the balanced wire (B).

The foot 5 of this terminal is soldered to a printed board or the like, but at this time, the pattern pitch corresponding to the pitch A of the foot 5 of the connector terminal is limited in the pattern production of the printed board and the reliability of soldering. The abnormal pitch A could not be reduced, and in consideration of mass production, the 1/10 inch pitch was the limit in the straight array. Therefore, it was not possible to increase the mounting density by making the pitch of the foot 5 of the terminal smaller than the limit.

The present invention has been made in order to solve the above problems, and by arranging the end of each foot of the connector terminal in a zigzag, the end of the foot of the terminal to be soldered to the printed circuit board, etc. in the conventional mountable pitch range and contacting the flat wire The pitch P of the contactor (same as the pitch between conductors of a balanced wire) can be reduced to almost 1/2 compared to a straight line arrangement, and a connector for increasing the mounting density is to be provided.

The present invention is a connector for connecting a balanced wire, wherein a connector of the connector terminal is bent to arrange the ends of a plurality of these foot portions in zigzag in two rows. Hereinafter, the present invention will be described according to the embodiment using the drawings.

2 is a view showing an embodiment in the case of the vertical structure of the present invention, (a) is a perspective view, (b) is a Y-Y 'cross-section shown in (a), (c) is the same Z-Z It is a figure which shows a cross section, respectively. In the drawings, the same reference numerals as those in FIG. 1 denote the same parts. In the figure, the structure in the wire insertion hole 3 of the connector 11 is exactly the same as in the case of FIG. The foot 15 of each connector terminal is 90 degrees in the thickness direction of the connector at the outlet of the housing 2 as shown in (b) and (c). Bent and then reversed to 90 It is bent so that the end 12 of the foot 15 is directed in the axial direction, which is the original direction. At this time, the direction in which the foot portions 15 of the adjacent terminals are bent is opposite to each other, and the distal ends 12 of the foot portions are opposite to each other from the original foot 15 axis line, and the pitch P (P is the contactor 4). Are arranged in two rows).

4 is a top view showing the arrangement of holes on the printed board on which the foot ends of the plurality of terminals in this case are inserted. As shown in the figure, the six holes 13 on the substrate are arranged in two rows zigzag with each other, there is a pitch 2P in the horizontal direction, and a pitch 2P in the vertical direction.

In other words, by arranging in a zigzag, the pitch of the ends of the foot portion is twice as large as the pitch P of the contactor. As a result, the pitch P of the contactor, that is, the pitch of the conductor of the balanced wire, can be reduced. Can be increased.

In this case, as shown in Figs. 2 (b) and 2 (c), the length of the foot 15 before bending is equal by adjusting the bending degree (in this case, P) of the foot 15 of each terminal in the same manner. It does not need to change the length for every terminal, and it is easy in manufacture. Next, FIG. 3 shows an embodiment in the case of the horizontal structure of the present invention, (a) is a perspective view, (b) is a cross-section C-C 'shown in (a), and (b) is the same as D- It is a figure which shows D 'cross section, respectively. In the drawings, the same reference numerals as those in FIGS. 1 and 2 denote the same parts.

In the figure, the structure in the wire insertion hole 3 of the connector 21 is the same as in the case of Fig. 2, except that only the second degree is vertical, but is transverse. The foot 25 of the connector terminal is alternated by 90 in the thickness direction of the connector at a position remote from the contactor 4 as shown in (b). The end 22 of the foot is vertical in the axial direction of the connector.

In this case, the space | interval (pitch) of the axis | shaft of the terminal part 22 arrange | positioned in 2 rows is set to 2P (P is the pitch of the contactor 4).

In this case, the arrangement of the holes on the printed board on which the ends of the foot portions of the plurality of terminals are inserted is the same as shown in Fig. 4, and since the pitch of the ends of the foot portions is twice the pitch P of the contactor, The pitch of the balanced wires can be reduced, and the mounting density can be increased.

In this case, the foot 25 of the terminal bent at a position close to the contactor 4 as shown in FIGS. When bent, the length of the foot 25 of each terminal before bending can be made the same by adjusting the bending degree more than the foot 25 of other terminals by giving a margin to bend, and there is no need to change the length for each terminal, Easy to manufacture In the present invention, the interval (pitch) of the two rows of axes of the holes into which the ends of the foot terminals of the connector terminals shown in FIG. 4 are inserted is exactly twice the pitch P of the contact, with the ends of the foot strangling with pitch. There is no need to do it, and there may be a slight difference between small and large, and even in these cases, it is clear that the present invention has an effect of increasing the mounting density.

As described above, in the present invention, in the connector connecting to the flat wire, the ends of the connector terminals are bent, and the ends of the plurality of biped portions are arranged in two rows in a staggered manner. Can be made almost twice the pitch P of the contactor, and the pitch P of the contactor, i.e., the pitch of the conductor of the balanced wire can be reduced by that much (up to almost 1/2), thereby increasing the mounting density.
