Description

[Detailed explanation of the idea] The present invention relates to a female connector.

Conventionally, it has been known to connect multiple connector units to each other to form a female connector corresponding to the number of wires, but when a large number of wires connected to the connector are bundled in the vicinity, other Since the connector units tend to separate from each other on the side where they are connected to the connector, there is a problem that it becomes difficult to connect the connector to the male connector. Conventionally, when a female connector is connected to a male connector, the female connector is detached from the male connector by rotating detachment members that are pivotally attached to both left and right ends of the male connector. However, many types of female connectors must be prepared depending on the number of cables to be connected to the female connector.

Furthermore, when multiple male connectors are arranged in a concentrated manner on a printed circuit board and a female connector is connected to the middle part of the male connectors, the male connector cannot be provided with a detachable member. When the male type connector is separated from the male type connector, the cable may be grasped and pulled out, which often causes the cable to break. Even when holding the insulator of the female connector to separate it from the male connector, a large amount of force is required and it is difficult to separate it vertically, which may bend the contacts and damage them, or damage the printed circuit board pattern. Sometimes. The purpose of the present invention is to eliminate such inconveniences, and in a female connector A constructed by interconnecting a plurality of connector units 1, a female connector A constructed by interconnecting a plurality of connector units 1 is provided. In the connector unit 1, first connecting protrusions 4D and 5D are formed on the connecting side of the male connector, and second connecting protrusions 4C and 5C are formed on the wire connecting side. 1, the first connecting protrusion pieces 3D, 6D are formed with arcuate recesses 10 that engage with the first connecting protrusions 4D, 5D, and the second Connecting protrusions 4C, 5
The arc-shaped recess 10 is provided on the side of the first connecting protruding pieces 3D, 6D that does not face the second connecting protruding pieces 3C, 6C. The second connecting protrusions 3c and 6c are formed on the side edges of the second connecting protrusions 3c and 6c. A protrusion 12 is formed at the tip of the opposing side edges of the piece, and the female connector A is attached to the connector units 1A and 1B at both left and right ends of the female connector.
detachment member 2A for detaching from the male connector B,
2B is pivotally connected. The drawing shows an embodiment of the invention.

In the drawing, the female connector A is composed of, for example, three connector units 1, and includes a connecting protrusion piece 3C formed on one side of the intermediate connector unit 1.
3D and the protrusions 4C and 4D formed on the other side, and the protrusion 5 formed on the 1 side of the connector unit 1A at the left end.
C, 5D and connecting protrusions 6C, 6D provided on one side of the connector unit 1B at the right end are engaged with each other to form an integral structure.

Separation members 2A and 2B for separating the female connector A from the male connector B are pivotally attached 7 to the other sides of the connector units 1A and 1B at both left and right ends.

When the female connector A is coupled to the male connector B, which is longer than the connector A, as shown in the first diagram,
To detach the female connector A from the male connector B, rotate the upper ends of the detachment members 2A and 2B to the left and right, so that the protrusions 8 and 8 at the lower ends of the detachment members 2A and 2B detach from the male connector B.
Since the insulator 9 is pressed, the female connector A can be moved vertically upward by the reaction force.
It can be done with light force by using leverage.

Connecting protruding pieces 3D, 6D on the connecting side of the male connector of the connector units 1, 1B
, an arcuate recess 10 is formed on the side edge of the side that does not face the connecting protruding pieces 3C, 6C on the wire connecting side, and the connecting protruding pieces 3C, 6C on the electric wire connecting side have the protrusions 5C, 4C. It consists of two pieces arranged in parallel with a fitting gap in between, and a protrusion 12 is formed inside the tip of each piece, thus connecting the connecting protruding pieces 3C, 3D of the connector unit 1 and the connector unit 1B. The connecting protruding pieces 6C, 6D,
When connected to the protrusions 5C, 5D and 4C, 4D of the other connector units 1A and 1 to be connected, the connector units 1, 1A,
Made it difficult for 1B comrades to separate.

In the above embodiment, the intermediate connector unit 1
Although one is used, two or more may be used or none may be used.

Further, by preparing predetermined types of connector units 1 having an appropriate number of contacts as the intermediate connector unit 1 and the connector units 1A and 1B at both left and right ends, many types of female connectors A can be provided by combining them.

In Fig. 1, the pins 11 of the male connector B that are not connected to the female connector A can be connected to each other with jumper wires (not shown) or connected to other female connectors. and use it.

As described above, according to the present invention, in a female connector A configured by interconnecting a plurality of connector units 1, in a female connector A configured by interconnecting a plurality of connector units 1,
First connecting protrusions 4D, 5D are formed on the male connector coupling side of the connector unit 1, and second connecting protrusions 4C, 5C are formed on the wire connecting side to connect the connector unit 1. On the connecting side of the other connector unit 1, first connecting protrusions 3D and 6D each having an arcuate recess 10 that engages with the first connecting protrusions 4D and 5D, and the second connecting protrusions 3D and 6D. 4C, 5C are provided, and the arc-shaped recess 1
0 is formed on the side edge of the first connecting protruding pieces 3D, 6D that does not face the second connecting protruding pieces 3C, 6C, and the second connecting protruding pieces 3c, 6c It consists of two parts arranged in parallel with a gap in which the projections 4C and 5C are fitted, and a projection 12 is formed at the tip of the opposing side edges of the two parts. Connector unit 1A at both ends,
Since detachment members 2A and 2B for detaching the female connector A from the male connector B are pivotally attached to the connector 1B, when a large number of electric wires connected to the contacts of the female connector are bundled near the connector, the male connector coupling side Even if a force is applied to separate the two connector units, they will not separate, and connection to the male connector will not become difficult. In addition, even when connected to the middle part of male connector B with a large number of contacts, it can be removed vertically with light force, preventing cable breakage, damage to pins, contacts, and printed circuit boards, etc. This has the advantage that many types of female connectors can be prepared at low cost depending on the number of cables.
