Abstract

(57) [Summary] [Structure] In a stacking connector for electrically connecting two printed circuit boards mounted in parallel, one of either a receptacle connector or a plug connector attached to each of the two printed circuit boards. If the legs of the contact are made flexible and a slider is provided at the position of the leg that abuts against the convex portion of the contact, the abutment with the contact is disengaged at the position where the slider slides and a load is applied to the entire connector. The legs of the contacts fall down to reduce the space between the two printed circuit boards. [Effect] The mounting space between PWBs to be mounted by stacking can be controlled to an arbitrary space, and even in a mounting method in which the mounting spaces are different, unified use can be achieved without increasing the types of connectors.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stacking connector for mounting an electronic computer or the like on an electronic circuit board used in electronic equipment.

[0002]

[Prior Art]

 As shown in FIG. 9 which is a sectional view taken along the line aa of FIG. 8 and FIG. 8, the conventional stacking connector has a receptacle connector 4 having a receptacle contact 21 attached to a PWB (printed circuit board) 1 and a plug contact attached to the PWB 2. When the plug connector 3 having the connector 22 is fitted, the space between the PWB 1 and the PWB 2 is determined by the shape of each connector.

[0003]

[Problems to be solved by the device]

 In the conventional stacking connector described above, the space between the two stacked PWBs is determined by the shape of the connector used. Therefore, if the space between the PWBs differs due to mounting conditions, etc., use the connector according to the space. However, there is a problem in that it is necessary to provide many types of connectors.

[0004]

[Means for Solving the Problems]

 The present invention comprises a receptacle connector and a plug connector that are mounted on two printed circuit boards that are mounted in parallel, and a plug contact of the plug connector is fitted into a receptacle contact of the receptacle connector. A first position which is provided between the receptacle connector and the plug connector in parallel with the board and has a hole for passing a leg portion of the plug contact (or the receptacle contact) and which allows the leg portion to pass through a narrow portion of the hole. And a slider that is movable between a second position where the leg portion is passed through the enlarged portion of the hole, and the protrusion provided on the plug contact (or the receptacle contact) is the slider that is the first portion. When in the position, contact the slider The space between the two print substrates is kept large, and when the slider is in the second position, the leg portion is deformed so that the convex portion enters the enlarged portion of the hole. The feature is that the space between the print substrates can be changed small.

【Example】

 Next, the present invention will be described with reference to the drawings.

FIGS. 1 and 2 are perspective views of an embodiment of the present invention. FIG. 1 is a view showing a large mounting space and FIG. 2 is a view showing a small mounting space. 3A and 3B are bb and cc sectional views of FIG. 1, and FIG. 6 is a plan view of the plug connector viewed from the receptacle connector 8 side in the state shown in FIG. The PWB 5 and PWB 6 are stacked and connected by the receptacle connector 8 and the plug connector 7 attached to each.

In the state shown in FIGS. 1, 3 and 6, the plug contact 13 of the plug connector 7 is fitted into the receptacle contact 12 with the convex portion 15 of the plug contact 13 being in contact with the slider 14. . FIG. 4 shows a state in which the slider 14 is slid in the direction of arrow f in FIG. 1 from the state shown in FIG. 3 to release the collision state between the protrusion 15 of the plug contact 13 and the slider 14. FIG. 7 is a plan view of the plug connector 7 in the state shown in FIG. 4 seen from the receptacle connector 8 side. In FIG. 6, the plug contact 13 is located in the narrow portion 25 of the hole 23 provided in the slider 14, whereas in FIG. 7, the plug contact 13 is located in the enlarged portion 24 of the hole 23.

FIGS. 5A and 5B are dd and ee sectional views of FIG. 2, respectively. 2 and 5, the leg portion 16 of the plug contact 13 of the plug connector 7 is deformed so that a force is applied diagonally downward to the PWB 5 and the receptacle connector 8 so that the convex portion is inserted into the enlarged portion 24 of the hole 23 of the slider 14. Then, the PWB 5 is brought closer to the PWB 6 to reduce the mounting space between the PWBs 5 and 6. Further, in order to secure a mounting space, a guide 9 is provided between the PWBs 5 and 6 and fixed by a screw 10 passing through a hole 11 provided in the printed circuit boards 5 and 6.

As described above, the mounting space between the PWBs 5 and 6 can be set to an arbitrary mounting space by controlling the approach amount between the PWBs 5 and 6 and changing and fixing the guide 9.

[0010]

[Effect of the device]

 As described above, according to the present invention, by providing flexibility to the legs of the connector contact, the mounting space between PWBs to be stacked and mounted can be controlled to an arbitrary space, and the number of types of connectors can be increased even if the mounting space is different. It has the effect that it can be used uniformly.

Claims (1)

[Scope of utility model registration request] 1. A stacking connector comprising a receptacle connector and a plug connector attached to each of two printed circuit boards mounted in parallel, wherein a plug contact of the plug connector is fitted to a receptacle contact of the receptacle connector. A first position which is provided between the receptacle connector and the plug connector in parallel with the board and has a hole for passing a leg portion of the plug contact (or the receptacle contact) and which allows the leg portion to pass through a narrow portion of the hole. And a slider that is movable between a second position where the leg portion is passed through the enlarged portion of the hole, and the protrusion provided on the plug contact (or the receptacle contact) has the slider at the first position. When it is in contact with the slider The space between the two printed circuit boards is kept large, and when the slider is in the second position, the leg portion is deformed so that the convex portion enters the enlarged portion of the hole, and thus the two printed sheets are printed. A stacking connector characterized in that the space between the boards can be changed small.
