DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in FIGS. 1 to 3. In FIGS. 1 to 3, reference numeral 1 denotes a connector, a connector housing 2 and a connector housing 2 mounted on the connector housing 2. And a flat cable 3. The connector housing 2 is composed of a pair of left and right connector housing portions 2A and 2B having the same shape, and the connector housing portions 2A and 2B have terminal mounting holes 4A penetrating in the vertical direction, respectively, in the longitudinal direction. Are provided at regular intervals.

Reference numeral 5 denotes a plate-like connecting portion which integrally connects the two connector housing portions 2A and 2B which are arranged side by side with the guide wall 4B formed on the upper surface outside at both ends in the longitudinal direction. The connecting portion 5 is formed with V-cut portions 5A above and below a central portion thereof so that the connecting portion 5 can be cut. Reference numerals 6 denote fixing legs to the printed circuit board, which are provided at both ends in the longitudinal direction of the connector housing portions 2A and 2B, respectively, and have hook portions 6A formed at lower ends thereof.

On the other hand, in the flat cable 3, a plurality of conductive wires 3B are arranged in parallel in a strip-shaped film 3A. At the same time, both ends of the strip-shaped film 3A are peeled off by a predetermined length and exposed to a terminal. 3C. The terminal portions 3C are respectively connected to the connector housing portions 2A,
2B is inserted into the terminal mounting hole 4A from above with the guide wall 4B as a guide, and the connector housing portions 2A, 2B
Are fixed in a state protruding from the bottom surface of the flat cable 3, and the pair of left and right connectors are connected by the flat cable 3.

Reference numeral 7 denotes a plate-shaped terminal protection member. The terminal protection member 7 has a through hole 7A formed at the same interval as the terminal portion 3C, and each of the through holes 7A protrudes from the bottom surfaces of the connector housing portions 2A and 2B. The terminal portions 3C are slidably inserted into the through holes 7A to prevent deformation of the terminal portions 3C during transportation or mounting. Numeral 8 denotes protrusions provided on the bottom surfaces of the connector housing portions 2A and 2B. Four projections are provided at positions off the outer periphery of the terminal protection member 7 so that the terminal protection member 7 is accommodated therein.

Reference numeral 9 denotes a split printed board (collective board) on which the connector 1 is mounted. The split printed board 9 is provided with a perforation or a V-cut notch 10, and two cut-offs can be separated by the cut 10. It is divided into single substrates 9A and 9B.

Next, a description will be given of the case where the connector 1 according to the present invention is mounted on the split printed circuit board 9 by an automatic insertion machine. More specifically, left and right-pair connector housing portions 2A, 2
One of B is gripped by the robot and is transported to the mounting position of the printed circuit board 9. At this time, since the left and right connector housing portions 2A and 2B are integrally connected by the connecting portion 5, the connector housing 2 is not deformed as a whole.

Therefore, both connector housing parts 2
The connector 1 is accurately placed at the mounting position of the printed circuit board 9 without any relative displacement of the terminal portions 3C of the flat cable 3 fixed to A and 2B, respectively. That is, as shown in FIG.
And the connector housing portions 2A and 2B of the connector 1 are mounted on the single substrates 9A and 9B, respectively. At this time, each connector housing part 2A, 2
The terminal portion 3C and the fixing leg 6 attached to B correspond to the terminal insertion hole 11 and the fixing hole 12 for the fixing leg formed in each of the single substrates 9A and 9B.

In this state, by pressing the connector housing portions 2A and 2B from above, first, the terminal portion 3C and the distal end of the fixing leg 6 enter the terminal insertion hole 11 and the mounting hole 12 of the fixing leg, respectively. By being further pressed, the terminal portion 3C slides in the through hole 7A of the terminal protection member 7, and the terminal portion 3C and the fixing leg 6 are respectively inserted to the bases thereof. At this time, the terminal protection member 7 is in contact with the lower surfaces of the connector housing portions 2A and 2B and is fitted between the projections 8 and 8 at positions off the outer periphery at the same time.
The connector housing portions 2A and 2B are supported on the printed circuit board 9 by the protrusions 8 integrated therewith. Therefore, the connector 1 is mounted on the printed circuit board 9 in a stable state without rattling.

Next, as shown in FIG. 3, if the split printed circuit board 9 is cut along the cuts 10, the connecting portion 5 of the connector 1 is cut at the center V-cut portion 5A at the same time as the printed circuit board 9 is cut. Be cut off. Thereby, the connector 1
And the single board 9A of the printed circuit board 9 and the other housing section 2B and the single board 9B of the printed circuit board 9.
Are separated into two parts, left and right, as one unit.
A and 9B are connected by a flexible central portion 3E of the flat cable 3.

Therefore, the single substrates 9A and 9B can be freely arranged in horizontal, vertical and parallel states. In the above embodiment, a split printed board is used as a printed board, but it is needless to say that one printed board or two independent printed boards may be used.

[0015]

As described above, the connector for printed circuit board connection according to the present invention has a pair of connector housings for mounting the terminals formed on both ends of the flat cable, respectively, and a pair of the connector housings extending longitudinally. A severable connection portion integrally connected at both ends in the direction, a plate-shaped terminal protection member slidably inserted into a portion of the terminal portion protruding below the bottom of the connector housing portion, and the terminal protection member A plurality of protrusions protruding from the bottoms of the pair of connector housing portions located outside the terminal protection member so as to house the inside, and legs for fixing to the printed circuit board provided on the pair of connector housing portions; , The connector can be securely mounted on the printed circuit board by the automatic insertion machine, and the efficiency of mounting work is greatly improved. And when this is mounted on a split printed circuit board, the connector is cut into two connector parts simultaneously with the cutting of the printed circuit board, and each single board can be freely arranged in horizontal, vertical and parallel states. The terminal area is slidably inserted into a terminal protection member arranged below the bottom of the connector housing part, so that the terminal area can be slidably inserted at the time of transportation or mounting. Deformation is prevented, and the effectiveness of the automatic insertion machine can be further improved. Further, at the time of mounting, the terminal protection member is housed between the plurality of protrusions and supported by the protrusions, so that there is an effect that the connector housing is fixed to the printed circuit board without rattling.
