Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector which is fixed to a printed circuit board and which is used to connect signals input to and output from the printed circuit board via cables.

Printed circuit boards used in electronic equipment include
Generally, a connector is mounted, and a signal input / output to / from a circuit network formed on a printed circuit board is formed by the connector.

On the other hand, when such an electronic device is a portable device, the outer shape of the housing for accommodating such a printed circuit board is made as small as possible, for example, a plurality of printed circuit boards are arranged in the thickness direction. Consideration is given to overlapping.

Therefore, it is desired that such a connector be formed so that the cables can be easily connected even when the printed boards are stacked in the thickness direction.

2. Description of the Related Art Conventionally, the structure was formed as shown in the conventional explanatory view of FIG. FIG. 4A is a side view, and FIG. 4B is a mounting explanatory view of the connector.

As shown in FIG. 4A, a lead terminal portion 12A is formed on one side and a terminal piece 12 on which a contact 12B is formed on the other side is held by a housing 11 made of an insulating material. The male side connector 10 is locked to the printed circuit board 1 by the mounting screw 13, and the female side connector 2 to which the cable 3 is connected is formed in the contact 12B so as to be detachable as shown by an arrow A.

The tip of the lead terminal portion 12A is formed so as to be bonded to the pad 5 arranged on the printed board 1. Therefore, by mounting the female connector 2 on the male connector 10, a predetermined signal to be input / output is connected to the printed circuit board 1 via the cable 3.

Therefore, when a plurality of printed circuit boards 1-1 to 1-N on which electronic components 15 are mounted are to be superposed, a spacer 14 is placed between the superposed printed circuit boards 1 as shown in (b).
Are formed so that there is a predetermined space S between the printed circuit boards 1 of each other, the male side connector 10 is mounted on the end faces of the printed circuit boards 1-1 to 1-N, and the female side connector 2 is mounted. Therefore, the cable 3 was connected to each printed circuit board 1-1 to 1-N.

[0009]

However, in the structure in which the male side connector 10 is mounted on the end surface of the printed circuit board 1 as described above, as shown in FIG. The distance T for inserting / removing the connector 2 is required, and even if the size of the printed circuit board 1 is L1 × L2, the occupied space of (L1 + T) × L2 is actually required, and a large occupied space must be secured. Therefore, there is a problem that the outer shape of the housing to be stored becomes large.

Therefore, an object of the present invention is to improve the efficiency of the occupied space for housing the printed circuit board.

[0011]

FIG. 1 is a diagram for explaining the principle of the present invention. As shown in FIG. 1 (a), a female connector 2 connected to a cable 3 and a pad 5 of a printed circuit board 1 are provided.
A male side connector 4 having a connector 6 connected to the male side connector 4, and by inserting the female side connector 2 into the male side connector 4, signal input / output to / from the printed circuit board 1 is performed by the cable 3. In the connector to be connected, the connectors 6 are arranged such that the connectors 6 are connected to the respective pads 5 of the plurality of the printed circuit boards 1 that are stacked in the thickness direction at a predetermined interval S. Arrangement surface 4A is formed stepwise, and (b1) (b2)
As shown in, the connector 6 is a pin so that the connector 6 and the pad 5 are connected by bonding.
7 or bumps 8 are formed.

The above-mentioned problems can be solved by such a configuration.

[0013]

Operation: That is, by forming the array surface 4A on which the connectors 6 of the male side connector 4 are arrayed in a stepwise manner, the pads 5 of each of the plurality of printed circuit boards 1 stacked in the thickness direction at the predetermined interval S are stacked. Is configured so that the connector 6 is connected to.

Therefore, it is not necessary to mount the male side connector 10 on the end surface of each printed circuit board 1 as in the prior art, the occupied space for housing the printed circuit boards can be reduced, and the size can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to FIGS. FIG. 2 is an explanatory view of an embodiment according to the present invention,
(a) is a side view, (b) is a plan view of the male connector, (c1) (c2)
FIG. 3 is a side view of a connector, FIG. 3 is an explanatory view of mounting a connector according to the present invention, (a) is a perspective view, and (b) is a plan view of a mounting portion.
Throughout the drawings, the same reference numerals denote the same objects.

As shown in FIGS. 2 (a) and 2 (b), the connector 6 is held by a housing 4B made of an insulating material, and the connector is connected to an array surface 4A formed in a stepwise manner from the central portion to the outer peripheral portion.
Male connector 4 formed so that 6 protrudes,
The female connector 2 to which the cable 3 is connected and the female connector 2 are configured to be inserted and removed as shown by arrow A.

Further, the male connector 4 is connected to the female connector.
By inserting and removing 2, the contact portion 6A of the connector 6 protruding from the opposite surface of the array surface 4A formed in a step-like manner is connected to the contact piece 2A of the female connector 2.

Further, the connector 6 in this case may be formed by the pin 7 as shown in (c1) or by the bump 8 as shown in (c2). .

Therefore, as shown in FIG.
When the 1-1 to 1-N printed circuit boards 1 are formed by the spacer 14 so as to be superposed at a predetermined interval S,
For example, by mounting the male connector 4 on the top printed circuit board 1 and inserting the female connector 2,
3 connections can be made.

In this case, the superposed printed circuit boards 1
For (b), as shown in (b),
Window hole 3-1 is for printed circuit board 1 in 1-1, and window hole 3-2 is smaller in size for printed circuit board 1 in 1-2 below.
In addition, the next 1-3 printed circuit board 1 should have a window hole 3-3 that is smaller in size than the window hole 3-2. 3-1 ~
3-3 are provided, and the pads 5 connected to the pattern are arranged around the respective window holes 3-1 to 3-3.

Therefore, the respective pads 5 of 1-1 to 1-N of the printed circuit board 1 on which the above-mentioned connector 6 is superposed.
It can be connected by bonding to.

With this configuration, the male connector 4
The mounting of the female connector 2 and the female side connector 2 is performed on the top surface of the printed circuit boards 1 that are stacked.
If the size of 1 is L1 × L2, it is almost the case that should be stored.
It is sufficient to secure the occupied space of L1 × L2, and it is not necessary to secure an extra space as in the conventional case, and the size can be reduced.

[0023]

As described above, according to the present invention,
By arranging the connectors in a staircase pattern so that the pads can be connected to each pad of the printed circuit board, the connector mounting can be prevented from protruding from the outer periphery of the printed circuit board. The occupied space can be reduced when the substrate is stored.

Therefore, as compared with the conventional case, the size can be reduced, and it is not necessary to mount a connector on each of the superposed printed circuit boards, so that the economy can be achieved and the practical effect is great.
