Description

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

Conventional connectors usually use a pair of male and female connectors having the same number of terminals.

For example, if the switching circuit shown in FIG. 1 is implemented using a connector, two 3-pin male connectors are required.

The switching circuit shown in FIG. 2 also requires two 3-pin male connectors.

In addition, as shown in Figure 3A, there is a switching function between connector connections, A
In order to add the MP function, etc., two 3-pin male connectors, one 5-pin male connector, and one 4-pin male connector are required as shown in FIG. 3B.

According to this example, using one pair of connectors requires a large number of assembly steps, component cost, and mounting space for mounting the connectors.

The present invention eliminates these drawbacks by facilitating semi-fixed switching connections and connection changes, and is formed so that multiple plug-side connectors can be connected to one jack-side connector, and prevents incorrect insertion. The present invention provides a connector structure characterized by having a structure for preventing reverse insertion.

The present invention will be explained in detail below using the drawings.

FIG. 4 shows an embodiment of the present invention.

In FIG. 4A, the female contact 1, which is the plug side connector, is made of an elastic metal material, and one end thereof serves as a connecting portion 12 for connecting the wiring 11 by soldering or crimping, and the other end is connected to the male contact 35. It has a structure in which it has a contact portion 13 that presses against it, and an elastic piece 14 that is locked and held in a side hole 23 of a male connector block 21 shown in FIG. 4B between both ends.

In the female connector 2 of FIG. 4B, the female connector block 21
is a molded product made of synthetic resin, and accommodates a plurality of female connectors 1 wired in contact holes 22.

At this time, as shown in FIG. 4A, there is a lock hole 23 at a position where the elastic piece 14 is caught, and is locked and held there.

When this locked elastic piece 14 is bent against elasticity in the direction of arrow A in FIG. 5A and the wire 11 is pulled, the lock is released and the female contact 1 can be pulled out.

This makes it easier to change wiring and replace broken wires.

There is an inclined protrusion 24 on the surface of this lock hole 23 that click-locks to the female connector 3 shown in Fig. 4B, so that you can feel the click in your hand, and also ensure that it is fully inserted and held so that it will not come out even in the event of vibration or impact. This is effective for ensuring reliability.

On the opposite side of these surfaces are guide protrusions 25 whose spacing is varied depending on the number of contacts to prevent incorrect insertion or reverse insertion.
26 is provided on the outer periphery of the insertion opening of the female contact 1 (the finger rest is provided as a flange 21 to facilitate insertion and removal).

Next, the male connector 3, which is the jack side connector, will be explained.

The male connector block 31 shown in the fourth diagram is a synthetic resin molded product with the guide walls 33 and 34 of the female connector 2 around the base portion 32, and the male contacts 35 are placed at positions matching the pitch of the male contacts 1 of the female connector 2. is fixed, the upper part is a part that contacts the contact part 13 of the female contact 1, and the lower part is a terminal part for connection to another circuit.

The guide wall 33 is provided with a cut-out portion 31 at the bottom to make the upper part an elastic body 36, and when the inclined protrusion 24 of the female connector 2 passes through this elastic body 36, the hand feels resistance. After passing, the inclined protrusion 24 enters the cut-out portion 3γ and is locked.

This results in a click effect and complete insertion, so highly reliable contact can be made without causing incomplete contact.

The guide wall 34 has guide protrusions 25 and 26 of the female connector 2.
Recesses 3B and 39 are provided at the positions where they engage with each other, and the row cannot be inserted unless the recesses and recesses of the two are aligned, completely preventing erroneous insertion.
Reverse insertion can be prevented.

The structure and operation of the present invention have been explained above, but to explain a few embodiments of the present invention, in order to perform the switching circuit as shown in Fig. 1 with a connector, normally two 3-pin male connectors and a female connector are used. Although this can be done by replacing one connector, in the present invention, if a recessed guide 40 is provided on the inner surface of the 4-contact male connector as shown in FIG. 6, it can be used in combination with one 3-pin female connector.

In other words, the bond state shown by the solid line is changed from the bond state shown by the dotted line (
It can be rubbed.

Even in the switching circuit as shown in FIG. 2, if the recess guides 41-1 to 41-4 are placed on the inner surface of the 6-contact male connector as shown in FIG. 7, the 3-pin female connector shown in FIG.
Can be executed in combination with individual.

That is, it is possible to rub the bonded state shown by the solid line and the bonded state shown by the dotted line.

In addition, when performing an additional function between connector connections as in the circuit shown in Fig. 3A, the male connector side should be guided in the recess as shown in Fig. 8B with respect to the 4+3+8 contact female connector shown in Fig. 8A. 42-1 to 42-7 are provided so that they are mated in place, and when there is no additional mounting, the 3-pin female connector is brought into contact with the recessed guides 42-6 to 42-7, and when additional mounting is performed, Connect the 3-pin female connector to the recess guide guide 42-3.
42-4 and insert an 8-pin female connector into the empty space, it is guaranteed that the connector will be safe and reliable without being inserted incorrectly or reversed.

Although the above example shows an example in which the plug side of the connector is a female connector and the jack side is a male connector, it is clear that it can be implemented even if the plug side is a male connector and the jack side is a female connector.

As described above, in the present invention, the jack side connector has more terminals than the plug side connector, and the uneven pattern guide on the inner wall of the jack side connector and the uneven pattern guide on the row wall of the plug side connector are set in advance. It is characterized in that it is formed so that mutual coupling is possible in a regular coupling posture at a plurality of coupling positions.

As explained above, according to the present invention, the click lock can be felt in the hand with a simple structure, complete insertion is guaranteed, and the reliability of the contact is greatly improved.

The guide protrusion on the plug side connector and the multiple recesses on the jack side connector that engage with it allow for interchangeable connections of switching circuits and split connections of the plug side connector, preventing incorrect insertion and reverse connection of many minor circuits. □ It has a great effect on assembly man-hours, parts costs, and mounting space.
