[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a butt type connector unit in which a pair of connectors are brought into contact with each other by a butt type.

[0002]

2. Description of the Related Art FIGS. 6A to 6C show the structure of a conventional butting type connector unit in a state where a connector is detached. This connector unit includes, for example, a first connector 100 and a second connector 200 that can be fitted and detached from each other, as shown in FIG. The first connector 100 is provided with first and second terminals 1 and 2 which are in a detached state of the first and second connectors 100 and 200 and are in abutting contact with each other, on an insulator. The connector 200 is separated from the first and second connectors 100 and 200 in a detached state.
A pair of terminals 4 is provided on an insulator. A groove 5 is formed on the upper surface of the insulator 3 of the second connector 200 as shown in FIG. Further, as shown in FIG.
When the connectors are fitted, the first connector 10
0, the two terminals 1 and 2 are separated from each other by the groove 5 of the insulator 3 of the second connector 200, and the second terminal 2 comes into contact with one of the pair of terminals 4 of the second connector 200. Has become.

[0003]

As described above, the conventional butt-type connector unit has a structure in which the first and second terminals 1 and 2 of the first connector 100 make a butt-type contact. Foreign matter easily enters the contact portions of these two terminals. Further, even if an oxide film is formed on the surfaces of both terminals, there is no structural consideration for removing the oxide film. For this reason, the conventional butting type connector unit has a drawback that a contact failure easily occurs during use. In order to avoid such poor contact, it is sufficient to increase the contact pressure between the two terminals, but on the other hand, such a configuration is difficult to implement due to space restrictions.

The present invention has been made in view of such circumstances, and a technical problem of the present invention is to provide a butt-type connector terminal which is less likely to cause poor contact and which can be maintained for a long time.

[0005]

According to the present invention, there are provided a first connector and a second connector, and the first connector is brought into abutting contact with the first and second connectors in a disengaged state. The first and second terminals are provided on an insulator;
Is a butting type connector unit comprising a pair of terminals provided on an insulator in a detached state of the first and second connectors, wherein the first and second terminals are the first and second terminals. And in the mating state of the second connector, the second connector is separated from each other by a groove provided in an insulator of the second connector, and the second terminal is capable of contacting a pair of terminals. A terminal connector has side projections, and a butt-type connector unit is obtained in which the groove has an inner projection in an arrangement capable of engaging with the side projection.

[0006]

The butt-type connector unit according to the present invention comprises a side projection provided on the first terminal of the first connector when the first and second connectors are released from the fitted state, and a second connector. The first terminal of the first connector is moved laterally with respect to the (fitting) disengagement direction by the engagement of the two projections with the inward projection provided in the groove portion of the second connector. It has a structure that slides on.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described in detail below with reference to embodiments. 1 to 5
1 shows an embodiment of the butting type connector unit of the present invention. As shown in FIG. 1, the butting connector unit includes a first connector 100 shown on the BB line side.
And the second connector 200 shown on the AA line side. Further, as shown in FIGS. 1 and 2B, the first connector 100 includes first and second connectors 10 and 10.
The first and second terminals 1 and 2 which are in a detached state of 0 and 200 and are brought into abutting contact with each other are provided on an insulator. Further, as shown in FIGS. 1 and 2A, the second connector 200 includes first and second connectors 100 and 200.
And a pair of terminals 4 which are separated from each other in a detached state.

In addition, the insulator 3 of the second connector 200
A groove 5 as shown in FIG.
In the fitted state of the first and second connectors 100 and 200, the two terminals 1 and 2 of the first connector 100 are separated from each other by the groove 5 of the insulator 3 of the second connector 200, and Terminal 2 of the second connector 20
0 terminal 4 Such a configuration is the same as that of the conventional butting type connector unit.

Further, in the present invention, as shown in FIGS. 1 and 3, the first terminal 1 of the first connector 100 is provided with a lateral projection 7. Correspondingly, as shown in FIGS. 1, 2A and 5, the groove 5 of the second connector 200 is also provided with the inner protrusion 6 so as to engage with the protrusion 7 described above.
Is formed.

[0010] The butting type connector unit having the above-described structure is provided with the first terminal 1 provided in the first connector 100.
Are provided with the side protrusions 7 and the inward protrusions 6 are provided in the groove portions 5 provided in the second connector 200. Therefore, when the first and second connectors 100 and 200 are separated from the fitted state, When the first terminal 1 comes into contact with the second terminal 2 at the contact portion 8, the first terminal 1 moves laterally with respect to the (fitting) disengagement direction due to the engagement of the projections 6, 7. A structure in which the contact portion 8 slides on the second terminal 2 is obtained. Thereby, even if a foreign substance is interposed in the contact portion 8, the foreign substance is removed by the sliding of the terminals 1 and 2. Further, the oxide film at the contact portion 8 can be removed by the sliding of the terminals 1 and 2. When the first and second connectors 100 and 200 are fitted with these preconditions, the first and second terminals 1 and 2 are separated from each other by the groove 5 and the second terminal 2 is It is in contact with one of the pair of terminals 4. Therefore, such a butting type connector unit is
Since the wiping function is added, the structure is such that a contact failure is not easily caused at the time of fitting.

[0011]

As described above, according to the butting type connector unit of the present invention, when the first and second connectors are fitted, both terminals of the first connector are separated from each other, and And when detaching the second connector,
Since both terminals are rubbed against each other, foreign matter has invaded the contact surface between both terminals, or even if an oxide film is formed, it is only necessary to repeat fitting and disengaging with each connector. , Can be effectively removed. As a result, a wiping function can be obtained, stable contact can be obtained at all times at the time of fitting, and maintenance can be unnecessary for a long time. As a result, the reliability of use in the butting type connector unit can be greatly improved.
