DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a connector having a plurality of electrical circuit connection terminals, and particularly to a rectangular multi-connector that can be provided at low cost with reduced manufacturing costs.

(b) Conventional technology Fig. 2 is a side view showing a conventional configuration of a connector in which a female connector is attached to a male connector mounted on a printed board, Fig. 3 is a perspective view showing the male connector, and Fig. 4 is a perspective view showing the male connector. FIG. 3 is a perspective view showing a configuration example of a male connector different from that in FIG. 3;

In FIG. 2, 1 is a male connector, 2 is a female connector, and 3 is a cable. Connector 1 has a plurality of connector terminals (male contacts) 11 that protrude downward, and the lead portions are connected to through holes in printed board 4. mated and soldered.

On the other hand, in the cable 3 formed by bundling a plurality of signal wires, each signal wire is connected inside the connector 2 to a plurality of connector terminals (not shown) inserted into the connector 2. .

In the figure, 12 is a locking hook for maintaining the fitting of connectors 1 and 2, and 13 is a pin for attaching hook 12 to the insulator of connector 1.
2 is capable of swinging around a pin 13.

In FIG. 3, the connector 1 has two or more terminals 11 on an insulator 14 formed by molding an insulating resin.
Planted in rows. When the connector 1 is mounted on a printed circuit board, in order to prevent solder flux from adhering to the upper part of the terminal 11 and damaging the electrical connection with the female contact, insert the middle part of the terminal 11. An insulator 14 is formed.

In FIG. 4, a connector 5 similar to the connector 1 has a plurality of connector terminals 52 embedded in an insulator 51 formed by molding an insulating resin, and the terminals 52 are electrically connected to the insulator 51. A pair of side walls 53 are integrally formed to protect the parts.

(c) Problems to be Solved by the Invention In the conventional connector 1 described above, the insulator 14 that holds the plurality of terminals 11 and the pair of hooks 12 is integrally formed as a whole, and It was formed by inserting a part of the terminal 11.

On the other hand, the connectors 1 and 5 and the connector (not shown) in which the side wall 51 is formed only on one side are essentially the same type,
For these connectors, special molds for forming various types of insulators are prepared depending on the number of terminals 11, etc. In particular, the molds for inserting the middle part of the terminals when molding the insulators are had become complicated.

Therefore, with conventional connectors, not only is mold management troublesome, but also the complicated mold structure has hindered improvements in productivity and cost reduction of connectors.

(d) Means for solving the problem The above problem can be solved by cutting a rod-shaped insulator, on which a plurality of connector terminals are embedded in the longitudinal direction at an appropriate pitch, into the required length.
The connector is formed by fitting the same into a support, and further, the connector terminal is formed by inserting the intermediate part and molding the insulator, and the support is formed by molding an insulating resin. The insulator has a rectangular cross section, and a notch for cutting is provided on each intermediate portion (both on the negative side) in which a plurality of the connector terminals are implanted. This is accomplished by a connector.

(e) Function According to the present invention, a conventional insulator is divided into an insulator on which a terminal is implanted and a support on which the insulator is supported, and
The insulator, which is formed into a long length and has a large number of terminals implanted therein, is cut into appropriate lengths and inserted into the support body to complete the connector. The connectors were standardized, and the molds used for them became simpler in structure, improving the productivity of connectors and making it possible to provide inexpensive connectors to users.

(f) Embodiments Below, connectors according to embodiments of the present invention will be explained using the drawings.

Fig. 1 is a perspective view of a connector according to an embodiment of the present invention with the locking hook removed (A) and its exploded perspective view (U), and Fig. 5 is an insulation diagram of a connector according to another embodiment of the present invention. Front view (A) and side view (El) of the long insulator from which the body is collected
It is.

In FIG. 1(A), the connector 6 includes a support 61 formed by molding an insulating resin, and an insulator 62 formed by molding the middle portions of a plurality of male terminals 64 implanted with an insert. It is composed of an insulator 63 formed by implanting a plurality of male terminals 64.

In FIG. 1 (El), the support body 61 has two pairs of flanges 611 at its longitudinal ends on which locking hooks (not shown) (corresponding to the hooks 12 in FIG. 2) are swingably attached. The insulators 62 and 63 are protruded so that the upper connection part and lower soldering part (lead part) of each terminal 64 are exposed.
A through hole 612 is formed into which the holder is fitted.

However, the insulators 62 and 63 are made longer than these and cut with an appropriate cutter to the required length, and the long insulators are used to cut the terminals 64 in a connector with multiple rows of terminals 64. It is commonly supplied to connectors in which the parallel spacing between the pinch and the terminal 64 is common.

In addition, in a connector in which the terminals 64 are arranged in a row,
The pitch of the terminals 64 is commonly supplied to connectors having the same pitch.

In FIG. 1(a), the insulators 62 and 63 are fixed to the through hole 612 of the support 61 by adhesive or other means.

In FIG. 5, a long insulator 7 formed by inserting the intermediate part of a terminal 64 and molding an insulating resin has a notch 72 having a 7-shaped cross section on one opposing side 71 in the length direction. At the time of mold formation, the terminals 64 are simultaneously formed at the intermediate portions of the planting pitches.

Therefore, when trying to obtain the above-mentioned insulators 62 and 63 from the insulator 7, the notch 72 corresponding to the length of the insulators 62 and 63 can be cut by hand, and the cutting can be done using a cutting tool. This is extremely convenient as it can be done without having to do anything.

In the above embodiment, the connector 6 is arranged in two rows of terminals, but the present invention is not limited to this embodiment. For example, the connector 6 has one row of terminals or a connector with two or more rows. Applicable. In addition, it is also possible to implement the same method in the case of a hook terminal which is a terminal with a terminal 64.

Further, as shown in FIG. 5 of the above embodiment, in a connector formed by inserting an insulator cut to a required length from a long object having a cutting notch formed therein, a notch is formed in the middle of the insulator. By forming in advance on the support a protrusion into which the notch fits, the insulator can be positioned accurately.

(g) As described in detail, according to the present invention, the insulator on which connector terminals are implanted is commonly supplied to connectors composed of terminals of the same type, so that the configuration of the connector mold is improved. The simplification improves productivity, and the reduction in manufacturing costs makes it possible to supply inexpensive connectors, which is a remarkable effect.
