Abstract

PURPOSE:To provide a slant fit connector of such a structure that the fit allowable angle remains small as it is, in the case a certain fit length is required according to the selection, and that the fit allowable angle A can be set off large in the case no fit length is required. CONSTITUTION:A couple of connectors 10, 20 to be fitted each other have fit reference surfaces 11, 21 which are perpendicular to the insering direction, and a spacer 30 removable is mounted on the fit reference surface 21 of one connector, wherein the arrangement should be such that the two reference surfaces 11, 21 confront each other while pinching the spacer 30 when the two connectors 10, 20 are fitted together. The connector 20 has a projected part 22 on the inside of the reference surface 21, and the spacer 30 should preferably be arranged as surrounding this projected part 22.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mating connector,
More specifically, for example, when the printed board is inserted into the apparatus housing, the connector of the printed board is fitted into the connector on the apparatus housing side at the same time as the insertion to electrically connect the printed board and the apparatus side. For such connectors.

[0002]

2. Description of the Related Art Conventionally, as a user's demand for a connector of this type, it is required that the mating length be long in order to ensure the mating of the connectors and to lengthen the contact portion of the terminals. , And the request to widen the fitting angle in order to facilitate the fitting operation.
One demand is increasing. However, no conventional mating connector satisfies these two contradictory requirements at the same time.

[0003]

When the fitting length is increased in a pair of connectors, for example, as shown in FIG. 3 (a), one end of the fitting reference surface 11 of one connector 10 is at the point B and the other is at the other end. Corresponding mating reference surface 2 of the connector 20 of
When this connector is rotated around the point B in accordance with the position of one end on the connector 1, the fitting reference surface 1 of the connector 10
The inner edge on the opposite side in 1 hits the tip of the corresponding wall of the projection 22 of the other connector 20 at point C, and the connector 1
There is a problem that the insertion and the fitting between 0 and 20 cannot be performed smoothly. That is, the fitting allowable angle A ° of the connector becomes small, and if the connector is forcibly inserted, it causes a wall crack in the block of the connector which is usually made of resin or the like.

The position of point B, which is the rotation reference position, is set so that the inner edge of one connector 10 does not collide with the wall of the projection 22 of the other connector 20.
If one attempts to insert and mate it away from, the mating length will be reduced and one of the above requirements will not be met. Therefore, an object of the present invention is to keep the fitting allowable angle A small when a relatively long fitting length is required by selection, and to increase the fitting allowable angle A when the fitting length is not required so much. An object is to provide a fitting connector adapted to be taken.

[0005]

In order to achieve the above object, according to the present invention, as shown in FIG.
In a pair of connectors 10 and 20 that can abut each other at fitting reference surfaces 11 and 21 that are perpendicular to the insertion direction, a spacer 30 is detachably attached to the fitting reference surface 21 of one connector 20 and the spacer is attached. Then, when the two connectors are fitted together, a diagonal fitting connector is provided in which the fitting reference surfaces of the pair of connectors face each other with the spacer interposed therebetween. Further, one connector 20 has a convex portion 22 inside the fitting reference surface 21, and the other connector 10 has a concave portion 12 fitted inside the fitting reference surface 11 to fit the convex portion. It is desirable that 30 be attached so as to sandwich the convex portion 22 of the one connector.

[0006]

In the present invention, since the spacer 30 is provided so as to be removable, the spacer 30 is mounted and the spacer 3 is attached when the fitting allowable angle is large even if the fitting length is shortened.
It is only necessary to fit the pair of connectors 10 and 20 to each other with the 0 attached. In addition, when it is not necessary to set the fitting allowable angle to a large value, the spacer 30 is removed and fitted. In this case, the fitting length can be increased.

[0007]

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 shows a state in which the printed board 2 is inserted into the device housing 1. One connector 20 is fixed to the front edge of the printed board 2, and the device housing corresponding to this printed board connector is shown. The other connector 10 is fixedly installed at the position 1. When the printed board 2 is moved in the direction of arrow P in order to insert the printed board into the apparatus housing, the connector 20 on the printed board 2 side is fitted to the connector 10 on the apparatus housing 1 side.

FIG. 2A shows a pair of connectors according to the present invention, and FIG. 2B is a sectional view taken along the arrow BB of FIG. The connector 10 is a concave connector (plug),
The connector 20 is a connector (jack) on the convex side. The connector 10 has a recess 12 that is recessed from the fitting reference surface 11, while the connector 20 has a projection 22 that projects from the fitting reference surface 21. In the present invention, a substantially U-shaped or horse-shoe shaped spacer 30 is arranged so as to contact the fitting reference surface 21 of the connector 20 and surround the convex portion 22. Such a spacer 30 is made of a flexible material such as resin or hard rubber having a predetermined thickness t, and is projected laterally with respect to the plug insertion direction P.
When the spacer 30 is pushed in, it is held at a predetermined position so as to be urged inward by the elastic restoring force of the spacer 30 itself.

FIG. 3 (b) shows the inserted / fitted state of the connector of the present invention. Since the connector 20 has the spacer 30 attached thereto, when the end edge of the fitting reference surface 11 of the connector 10 is rotated with reference to the position B ′ of the end edge of the spacer 30, the fitting reference surface 11 of the connector 10 is rotated. The inner edge on the opposite side does not hit the tip portion C ′ of the corresponding wall of the connector 20, and the insertion can be smoothly performed. That is, the fitting allowable angle A ° is considerably larger than that without the spacer shown in FIG.
Even if it is forcibly inserted into 0, the wall crack of the connector block made of resin or the like does not occur.

FIG. 4B shows the connector of the present invention,
Shows the state where insertion / fitting is completed. Compared with the case without the spacer 30 shown in FIG. 4 (a), the fitting length is shortened from D to D '(D>D'), but the allowable fitting angle is increased, so the connector insertion and fitting work is performed. Can be done easily. Depending on how the connectors are inserted and mated, the pair of connectors may not be in an oblique state with each other, and if it is not necessary to set the mating allowance angle too large, the spacer should be pulled out laterally from the other connector (plug). It is enough. In this case, as a matter of course, as shown in FIG. 4A, the fitting length D can be made long.

Although the embodiments have been described in detail with reference to the accompanying drawings of the present invention, the present invention is not limited to the above embodiments, and various embodiments within the spirit or scope of the present invention, It should be noted that variations, modifications, etc. are possible. For example, the shape of the concave portion 12 of the connector 10 and the convex portion 22 of the connector 20 is shown as an inverted trapezoid as shown in FIG. 2B, but it is not necessary to have such an inverted trapezoid, and a rectangular shape, for example, It may be circular or any other shape, and the spacer 30 can be easily formed into an appropriate shape in accordance with these shapes.

[0012]

As described above, according to the present invention, since the spacer is detachably provided on the connector,
Depending on the selection such as when the fitting allowable angle needs to be large, or when the fitting allowable angle needs to be large, the spacer can be attached or detached, and a low-cost and versatile connector can be obtained. it can.
