[Industrial application field]

The present invention relates to a connector fitting for temporarily fixing a connector so that it does not float up from a printed board until it is soldered when it is mounted on a printer board.

When the connector is mounted on the printed board by soldering, a means for temporarily fixing the connector so as not to be displaced from the proper position during the soldering work is taken.

For this reason, it is necessary to provide a mounting member that is temporarily fixed by inserting it into the through hole of the printed board.

[Conventional technology]

 FIG. 2 is a view showing a conventional mounting member.

In the figure, reference numeral 1 denotes a connector mounted on a printed board 2, which has a plurality of contacts having a contact portion 11a and a terminal board 11b.
11 is embedded in the insulator 12.

Mounting holes 12a are formed at both ends of the insulator 12, and the through holes 21 of the printed board 2 are normally formed by fastening means such as screws.
Although it was fastened and attached to the mounting bracket 3 recently, in order to reduce the screw fastening work, recently, the mounting bracket 3 having the spring portion 31 whose elastic diameter can be reduced elastically at the tip is attached to the insulator 12 as shown on the right side of the drawing. It is press-fitted and fixed in the hole 12a in advance, and the spring portion 31 is inserted into the through hole 21 of the printed board and temporarily fixed to perform dip soldering.
A method of completing mounting by soldering and fixing 3 and 3 to the printed board 2 is used.

The conventional mounting member 3 used for this purpose is manufactured only by punching a spring plate material, has two legs that are divided by a central groove and are elastically displaceable in the plate width direction, and have a through hole. The projection portion of the leg portion having a size larger than the hole diameter of 21 is elastically displaced and inserted into the through hole 21 to pass therethrough, and the projection is hooked on the lower surface of the so hole 21 to hold the connector on the printed board.

[Problems to be solved by the device]

For the above applications, a mounting bracket that can cover a wide range of through hole diameters is desirable. However, with only punching,
In the conventional mounting bracket that bends only in the plate width direction, the width of the protrusion must be made larger than that in order to hook it on the back surface of a large-diameter through hole, and when applied to a small-diameter through hole, The amount of deflection when the protrusion passes through the through hole is too large, and the insertion force becomes excessive, which causes various problems when mounting the connector on the printed board using the automatic component mounting device or the like. .

The present invention has been made in view of the above problems, and it is possible to temporarily fix a connector to a printed board having a wide range of through-hole diameters by bending the contact piece in the board thickness direction and the board width direction. It is intended to provide a flexible connector mounting bracket.

[Means for Solving the Problems]

The above-mentioned conventional problem is a fitting for temporarily fixing the connector to the through hole of the printed board.The fitting is made of a spring plate material, and is inserted into the stopper part wider than the diameter of the fitting hole of the connector and the fitting hole of the connector at the upper part. Having a press-fitting portion and two elastic strips extending downward from the press-fitting portion and having a substantially Π shape, and one side of the elastic strip is formed in a substantially V-shape by the protruding portion. , And the fittings of the connector of the present invention and the connector into which the fittings are fixed by being bent so as to open the middle part of the two sheets in opposite directions in the plate thickness direction. Will be resolved.

[Action]

At the middle of the strip, the protrusion widens the width of the strip, and by bending it in the thickness direction, the circumscribed circle becomes larger than the conventional product, and it can be temporarily fixed to a through hole with a large diameter. it can.

That is, when the diameter of the through hole is large, it passes through the through hole only by bending in the plate thickness direction, but when the diameter is small, in addition to the bending in the plate thickness direction, the diameter of the circumscribing circle is further bent by bending in the plate width direction. It has a smaller two-step operation. Therefore, the range of applicable through-hole diameters is expanded.

〔Example〕

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a fitting for a connector of the present invention.

In FIG. 1, the mounting member 4 is manufactured by pressing a spring plate material and subsequent solder plating, and includes a stopper portion 41 wider than the diameter of the mounting holes 12a at both ends of the insulator 12 of the connector 1, and A press-fitting portion 42, which has the same width as the diameter of the mounting hole 12a and is press-fitted and fixed in the mounting hole 12a by a projection 42a on the side surface, is formed in the upper part, and the lower side thereof is an appropriate slit and two elastic strips 43. , 44, and the whole is roughly Π
It is shaped like a letter.

The outer edges of both the elastic strips are punched out by the protrusions 43a and 44a so as to have a wide intermediate portion on the outside, and the two intermediate portions are opposite to each other in the plate thickness direction so that the intermediate portions are opened. It is bent into a V-shape.

The bending amount of the above-mentioned elastic strips 43, 44 is set so that the diameter of the circle C circumscribing the vertex of the V-shaped bending is sufficiently larger than the inner diameter of the through hole 21 of the printed board 2 to be inserted.

After the mounting bracket 4 configured in this manner is press-fitted and fixed to the connector 1, the lower end of the mounting bracket is attached to the through hole 21.
The operation of the mounting bracket when the connector 1 is mounted on the printed board 2 by inserting into the connector will be described.

The fitting of the present invention is not in the same plane at the middle portion of the two strips, and compared with the strip width direction (x direction) of the strips,
Since the stiffness in the plate thickness direction (y direction) is small, when it is inserted into the through hole, the elastic strip bends in the plate thickness direction so that the distance between the peaks of the bent bending becomes small.

That is, when the diameter of the through hole 21 is larger than the distance in the x direction between the projecting portions of the two strips, the bending peaks of the strips 43 and 44 are displaced inward by the through hole 21 as indicated by the arrow y. Then, the circumscribed circle C is squeezed, and the protruding portions 43a and 44a are the through holes 2.
After passing 1, the back side of the printed board opens halfway and is held by the printed board.

When the diameter of the through hole 21 is smaller than the above, the middle portion of the elastic strip is displaced in the plate thickness direction as described above and further displaced in the plate width direction as indicated by the arrow x, and the diameter of the circumscribed circle is further reduced. It can also pass through small-diameter through-holes, and then the middle part opens and the back surface of the printed board is prevented from coming off.

The connector temporarily fixed on the printed board as described above is soldered together with other components at a predetermined position and firmly fixed to the printed board without being lifted from the printed board in the dip soldering process.

As described above, the mounting bracket of the present invention is bent in the opposite direction so that it is displaced in the plate thickness direction and then further in the plate width direction during the insertion process into the through hole. It is possible to temporarily fix the connector to a through hole having a diameter larger than that of a conventional mounting member that uses only displacement in the plate width direction.

[Effect of device]

According to the present invention, it is possible to supply a mounting bracket capable of temporarily fixing a connector to a wide range of through hole diameters, and its practical effect is remarkable.
