Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector constructed by interconnecting a flat cable connector unit and an ordinary cable connector unit.

Conventionally, as a flat cable connector, as shown in the first diagram, an insulator (a) that houses a female contact and exposes the cable connection end, and a flat cable (b) that is connected to the cable connection end are coated. and an insulator c, and pins e provided at both left and right ends of the insulator c are fitted into grooves d formed at both left and right ends of the insulator a to connect both insulators a and d. It has been known.

In electronic equipment, ordinary cables are sometimes used in addition to flat cables, and in this case, ordinary cable connectors are used in addition to the above-mentioned flat cable connectors. Therefore, a large space is required, which has been an obstacle to miniaturization of electronic devices. Further, there were other disadvantages such as it took time and effort to attach to a wiring board, etc., and there were a large number of parts to be attached.

The object of the present invention is to provide a connector that solves the above-mentioned problems, and in which a connector is constructed by interconnecting a plurality of connector units 1, the connector unit 1
At least one of the connector units 1 is a flat cable connector unit 1A, and the remaining connector units 1 are ordinary cable connector units 1B. an insulator 5 which is exposed on the upper surface and has a joining protrusion 4 formed on the front and rear surfaces, and connecting members 11 and 13 formed on at least one of the left and right ends, and a flat cable insertion groove formed on the front surface and open on the side surface. 6, an insertion hole 7 of the cable connection end 3 that communicates with the groove 6 from the bottom surface, a locking piece 8 that locks into the projection 4 hanging down from the front and rear of the bottom surface, and the flat cable insertion groove 6.
The ordinary cable connector unit 1B has the flat cable connector 1B provided at least one of the left and right ends. Connecting member 1 of unit 1A
0, 11, 12, 13, a connecting member 18,
It is characterized by comprising an insulator in which 19, 20, and 21 are formed. Examples of the present invention will be described below.

2 to 6 show a flat cable connector unit 1A in the connector of the present invention.

At both left and right ends of the front and rear surfaces of the insulators 5 and 9,
Connecting protruding pieces 10, 11 and protrusions 12, 13 for connecting with other connector units 1 are formed.

A number of recesses 15 for guiding the flat cable 14 are formed on the lower surface of the flat cable insertion groove 6 of the insulator 9 at the same pitch as the core wire, and after the flat cable 14 is inserted into the groove 6, the flat cable 14 is inserted into the insertion hole. When the cable connecting end 3 is inserted into the connector 7 and the insulator 5 is pressed down, the cable core wire is connected to the connecting end 3 and the hole of the locking piece 8 engages with the coupling protrusion 4, so that both insulators are connected to each other. The bodies 5 and 9 are connected to form a single body.

In the drawing, reference numeral 16 indicates a relief hole for the cable connection end 3 of the female contact 2.

The connector unit 1A of the flat cable 14 has connecting protruding pieces 10, 1 as shown in FIG.
1 to another flat cable connector unit 1
By engaging the protrusions 12 and 13 of A, no wasted space is required at both the left and right ends, and a flat cable connector unit that can be applied to more multi-core flat cables can be constructed. In addition, the connecting protruding pieces 10, 1 of the connector unit 1A at the left end
1 is unnecessary, so delete it.

FIG. 8 shows an embodiment of the present invention.

In the same figure, the connecting protrusions 10 and 11 at the left end of the flat cable connector unit 1A are connected to the protrusions 18 and 1 of the connector unit 1B of the ordinary cable 17.
9, and the projections 12 and 13 at the right end are engaged with the connecting projections 20 and 21 of another ordinary cable connector unit 1B.

In this way, according to the present invention, at least one
one connector unit 1A for flat cables and at least one connector 1B for ordinary cables
Since the flat cable connector and the flat cable connector are connected to each other, it is possible to reduce the mounting space in electronic equipment, etc., compared to using separate flat cable connectors and ordinary cable connectors, and the electronic equipment, etc. can be made smaller. In addition, the connector can be easily attached to a wiring board, the number of attachment parts can be reduced, and the operation of coupling and separating the connector and the cooperating connector can be simplified.
