Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector for connecting two printed circuit boards on the same plane, and specifically relates to a connector for connecting two printed circuit boards on the same plane. It relates to connectors for connecting between

[Prior Art] A conventional connector for connecting two printed circuit boards on the same plane will be described with reference to FIG.

FIG. 3 is a cross-sectional view of the connector, 27, 28
is a contact, 37, 38 is an insulating block, 39
is a spacer, and 51 and 52 are printed circuit boards (PCBs) inserted in the directions of arrows 48 and 49. That is, insulating block 37, contact 27, spacer 39, contact 28, insulating block 38
It was composed of a five-layered structure.

[Problems to be solved by the invention] As shown in Figure 3, the number of parts is large, and the parts and management costs are high, and since the structure is laminated, assembly is not a simple task, so automation is not possible. Because it is difficult to assemble and requires a lot of man-hours to assemble,
Costs were becoming high.

[Means for solving the problem] The parts constituting the connector consist of a contact body and an insulating block. It has two contact pieces each having a base and a contact part obtained by molding a member extending parallel to the main guide part from the contact piece base, and the insulating block has a Z-shaped cross section at both ends of the contact hole. A plurality of guide grooves are provided in the contact hole, and two PCB grooves are provided for inserting a printed circuit board across the center of the contact hole.

[Function] By press-fitting the main guide portion of the contact body along the guide groove of the insulating block, the two contact pieces of the contact body are positioned in the contact holes. As a result, the contact bodies are arranged along the guide grooves at both ends of the contact hole so that the contact parts of the contact pieces approach each other and face each other, and the contact parts come into contact with the inserted printed circuit board. It turns out.

The connector is completed by simply press-fitting the contact body into the insulating block.

[Example] An example of the present invention is shown in FIGS. 1 and 2,
explain.

FIG. 1a shows a diagram showing the structure of the contact body and part of the insulating block, and FIG. 1b shows another embodiment of the contact body.

In Fig. 1, 10 is the contact body, 30
11 is an insulating block, and 11 serves as a guide when the contact body is press-fitted into the insulating block 30, and is a main guide portion for fixing the contact body 10 to the insulating block 30 after press-fitting. 1
2 and 13 connect the contact body 10 to the insulating block 3
This is an auxiliary guide part for assisting the guiding effect of the main guide part 11 when press-fitting the main guide part 11, that is, for facilitating the press-fitting work. Reference numeral 14 denotes a contact piece base projecting from near the center of the main guide portion 11. 15 and 16 respectively extend parallel to the contact body from the contact piece base 14 and have contact portions 25 and 26, respectively, for contacting a printed circuit board inserted at the tip thereof, and the contact portions 25 and 26 are connected to the contact body. It is a contact piece formed so as to rise from the surface of 10. 18 is a protrusion, 19 is a recess on the back surface of the protrusion 18, and 20 is a hook protrusion that overhangs the edge of the main guide portion 11.

A part of the structure of the insulating block 30 is shown in FIG. 1a, its entire structure is shown in FIG. 2a, its cross-sectional view is shown in FIG. 2b, and its longitudinal sectional view is shown in FIG. 2c. There is. In FIGS. 1a and 2 showing this insulating block 30, 32 is two PCB grooves for inserting a printed circuit board extending in the longitudinal direction of the insulating block 30, and 34 is a contact piece of the contact body 10. 15 and 16 are contact holes for positioning, 35 is a guide groove into which the main guide part 11 is press-fitted, and 2 for one contact hole 34.
Two guide grooves are provided in a Z-shape.

When the contact body 10 is press-fitted into the insulating block 30, the protrusion 18 bites into the inner wall of the guide groove 35, and the hook protrusion 20 also bites deeply into the side wall of the guide groove 35. It will be fixed at .

Here, the protrusion 18 and the hook protrusion 20 are located above the main guide portion 11 in the drawing of FIG. This means that when the contact body 10 is press-fitted into the insulating block 30 in the direction of arrows 40 and 41, almost no force is required for the press-fitting in most parts of the press-fitting process, and in the last part of the press-fitting process. This is to ensure efficient and reliable press-fitting work that only requires a large amount of force.

1b and 1c show embodiments of contact bodies 10 of other shapes.

FIG. 1B shows the main body 10 shown in FIG. 1A with the auxiliary guide parts 12 and 13 removed.

In FIG. 1c, a slit 21, which is a dividing groove, is formed in the contact piece base 14B, and the contact pieces 15B, 16B are bent perpendicularly to the surfaces of the main guide part 11 and the contact piece base 14B, and each of the contact pieces 15B, 1
Contact portions 25B and 26B are provided at the tips of 6B, respectively.
It has been established.

When the two printed circuit boards to be inserted have different thicknesses, the contact bodies 1 of the contact parts 25 and 26
This can be dealt with by adjusting the height rising from the zero plane.

[Effects of the invention] As is clear from the above explanation, according to the present invention, it is only necessary to repeat the simple work of press-fitting multiple contact bodies of one type into one insulating block, so automation is possible. The present invention provides an excellent planar connector with uniform characteristics, which is easy to use, has a small number of parts, reduces management costs and parts costs, and has extremely large effects.
