Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a connector for connecting two substrates.

[0002]

2. Description of the Related Art FIGS. 7 and 8 show a first conventional example of this type of connector. This has a housing A disposed on one substrate X, a base end supported by the housing A along the one substrate X, and an elastic member mounted on the other substrate Y superposed on the one substrate X. A contact provided with an elastic contact piece B1 having an elastic contact portion B11 in contact therewith is provided.

The contact B is connected to one of the substrates X
An elastic portion B1 is provided by bending the intermediate portion at an acute angle so as to have elasticity in a direction perpendicular to the elastic contact portion B1, and a distal end portion of the elastic contact portion B1 is gently bent to form an elastic contact portion B11.
The base end is soldered to one substrate X.

FIGS. 9 and 10 show a second conventional example of this type of connector. In this case, an extension piece A1 is extended in a comb-like shape along both edges, and a housing A disposed on one of the substrates, the extension piece A1 of the housing A passes between the extension pieces A1 of the housing A. A base end portion is supported so that a front end portion is drawn out from the back side to the front side, and an elastic contact portion B elastically contacts the other substrate Y which is arranged on one substrate and overlapped with the other substrate Y.
11 is provided with a contact B provided at the tip.

The contact B has a front end bent to form an elastic contact portion B11 having elasticity in a direction perpendicular to one of the substrates, and an intermediate portion formed inside the housing A by a U-shape. It is bent in the shape of a letter, and the base end is soldered to one of the substrates.

[0006]

In the connector of the first conventional example described above, the contact B has an intermediate portion bent at an acute angle so as to have elasticity in a direction perpendicular to one of the substrates. Since it has a shape protruding from the substrate X, there is a risk that it will be hooked by mistake, and if it is hooked by mistake, the elastic contact portion B11 will be deformed and elastically contact the other substrate Y that is superimposed. As a result, it is impossible to connect both substrates X and Y superposed.

In the connector of the second conventional example,
The contact B extends between the extension pieces A1 of the housing A and extends from the back side of the extension piece A1 to the front side so as to form an elastic contact portion B11 having elasticity in a direction perpendicular to the one substrate X. Because the part is bent in a letter shape, there is a risk of being hooked by mistake, and if it is hooked by mistake,
The elastic contact B11 is deformed and does not elastically contact the other substrate to be superimposed, so that it is not possible to connect both substrates superposed and arranged.

The present invention has been made in view of the above points, and an object of the present invention is to provide a connector which can reliably connect both substrates arranged in an overlapping manner.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Connector 1 according to one embodiment of the present invention
0 will be described below with reference to FIGS. The connector 10 connects one substrate 20 and the other substrate 30 that are arranged to overlap each other.

Reference numeral 1 denotes a housing, which is provided on one of the substrates 20. The housing 1 is made of an insulating resin material.
1. Opposing portion 1 disposed opposite to contact support portion 11
2. It has a connecting portion 13 for connecting the contact supporting portion 11 and the facing portion 12 on both sides, and is formed in a substantially frame shape.

The housing 1 is provided with an elastic contact piece 21 to be described later from its opposing portion 12 toward the contact support portion 11.
The protection part 12a which protects the front-end | tip part is extended in comb shape. The thickness of the protection portion 12a is smaller than that of the frame portion of the housing 1. Accordingly, the housing 1 has the same front side as the superposed surface that is superposed on the other substrate 30 that is superposed on the one substrate 20, but is different from the disposed surface that is disposed on the one substrate 20. On the rear side, only the frame-shaped portion is flush.

Reference numeral 2 denotes a contact having a base end on one substrate 2.
0, and the base end is supported by the contact supporting portion 11 of the housing 1 so as to be in parallel with each other along one substrate 20. The contact 2 has an elastic contact portion 21a which is cut and raised at an intermediate portion, and which is bent in a mountain shape so that the cut and raised portion has elasticity in the vertical direction of one of the substrates 20 and elastically contacts the other substrate 30. The elastic contact piece 21 is formed.

The tip of the elastic contact piece 21 is located between the front surface and the back surface of the protection portion 12a in side view, and is surrounded by the facing portion 12 and the protection portions 12a on both sides from three sides in plan view. Or the opposing portion 12 and one of the protection portions 12
a and the connecting portion 13 surrounds it from three sides. That is, the facing portion 12, the protection portion 12a, and the connecting portion 13 form the surrounding portion 3 that surrounds the distal end portion of the elastic contact piece 21.

In the contact 2, a tip portion other than the elastic contact piece 21 is integrally formed with the facing portion 12 as the surrounding portion 3.

In the connector 10, since the distal end of the elastic contact piece 21 of the contact 2 is protected by being surrounded by the surrounding portion 3, it is difficult for the connector 2 to be hooked by mistake and to be hooked. The elastic contact portion 21a is less likely to deform due to the elastic contact portion 21a, so that the elastic contact portion 21a elastically contacts the other substrate 30 arranged in an overlapping manner, and the two substrates 20, 3 arranged in an overlapping manner.
0 can be reliably connected.

Further, since the surrounding portion 3 is provided integrally with the housing 1, the number of parts can be reduced.

Further, since the surrounding portion 3 integrates a portion of the contact 2 other than the elastic contact piece 21, the positioning of the contact 2 can be more reliably performed.

Next, a connector 1 according to a second embodiment of the present invention will be described.
0 will be described below with reference to FIGS. Note that members having substantially the same functions as those of the first embodiment are denoted by the same reference numerals, and only differences from the first embodiment will be described.
In the first embodiment, the surrounding portion 3 surrounding the tip of the elastic contact piece 21 of the contact 2 is provided.
In the present embodiment, a configuration is provided in which an integrated member 4 formed by integrally molding the tips of the plurality of contacts 2 is provided.

The housing 1 has a contact support portion 11 which penetrates and supports the contact 2 and both side pieces 14 extending from both sides of the contact support portion 11 using a resin material having an insulating property. It is formed in a U-shape.

The contact 2 is bent in a mountain shape so as to have elasticity in the vertical direction of one of the substrates 20, and has an elastic contact portion 21 a elastically contacting the other substrate 30 at an intermediate portion.

Reference numeral 4 denotes an integrated member, which is formed in a flat plate shape by integrally molding the tips of the plurality of contacts 2 with a resin material having an insulating property.

In such a connector 10, the tips of the plurality of contacts 2 are protected by being integrally formed by the integral member 4, so that it is difficult for the connector 2 to be hooked by mistake and the hook is hung. Since the deformation of the elastic contact portion 21a is less likely to occur, the elastic contact portion 21a elastically contacts the other substrate 30 arranged in an overlapping manner, and the two substrates 20 arranged in an overlapping manner.
30 can be reliably connected.

Next, a connector 1 according to a third embodiment of the present invention will be described.
0 will be described below with reference to FIGS. Note that members having substantially the same functions as in the second embodiment are denoted by the same reference numerals.

The housing 1 is provided on one of the substrates, and is formed in a substantially rectangular parallelepiped shape from a resin material having an insulating property. In the upper part having a superposed surface, a plurality of extending pieces 1 having a substantially rectangular shape are formed from both edges along the longitudinal direction.
5 extend in a comb shape.

The contact 2 has its proximal end supported by the lower portion of the housing 1 and its distal end has the housing 1.
Are extended from the back side of the extension piece 15 to the front side. The contact 2 is bent at its distal end into an O-shape so as to form a resilient contact portion 21a having elasticity in a direction perpendicular to one of the substrates, and the T-shaped end is formed. In order to prevent the part from moving away from one of the substrates, a hook part 22 is provided which is hung on the back side of the extending piece 15 on both sides. The contact 2 has a middle portion bent in a U-shape in the housing 1 and a base end portion connected to one of the substrates by soldering.

In this connector 10, the tip of the contact 2 is erroneously prevented from moving away from one of the substrates by the hooking portion 22 being hooked on the back side of the extension piece 15. Even if it is hooked, it is difficult for the elastic contact portion 21a provided at the distal end portion to be deformed.
1a is in elastic contact with the other substrate arranged in the overlapping arrangement, and the two substrates arranged in the overlapping arrangement can be reliably connected.

Further, since the hooking portion 22 is hooked on the back side of the extending piece 15 on both sides, the hooking force is increased, and the elastic contact portion 22a provided at the tip end portion is hardly deformed. Further, an effect that the two substrates can be reliably connected to each other can be further obtained.

In the state where the hook 22 is hooked on the back side of the extension pieces 15 on both sides, the contact 2
Since the displacement along the longitudinal direction of the substrate is also restricted, it is possible to further exert an effect that the two substrates arranged in an overlapping manner can be reliably connected.

[0035]

According to the connector of the present invention, since the distal end of the elastic contact piece of the contact is protected by being surrounded by the surrounding portion, it is difficult for the connector to be erroneously hooked and is hooked. Since the deformation of the elastic contact portion is less likely to occur, the elastic contact portion elastically contacts the other substrate arranged in an overlapping manner, and the two substrates arranged in an overlapping manner can be reliably connected.

In the connector according to the second aspect, in addition to the effect of the connector according to the first aspect, since the surrounding portion is provided integrally with the housing, the number of parts can be reduced.

According to the third aspect of the present invention, in addition to the effects of the connector according to the first or second aspect,
Since the surrounding portion integrates portions of the contact other than the elastic contact pieces, the positioning of the contact can be made more reliable.

[0038] In the connector according to the fourth aspect, the tips of the plurality of contacts are protected by being integrally formed by the integral member, so that it is difficult for the connector to be hooked erroneously, and the contact is made elastic. Since the deformation of the portion is less likely to occur, the elastic contact portion elastically contacts the other substrate arranged in an overlapping manner, and the two substrates arranged in an overlapping manner can be reliably connected.

In the connector according to the fifth aspect, the distal end of the contact is restricted from moving away from one of the substrates by the retaining portion being retained on the back side of the extension piece.
Even if it is hooked by mistake, deformation of the elastic contact portion provided at the distal end portion is less likely to occur, so that the elastic contact portion elastically contacts the other substrate arranged in an overlapping manner, and the two substrates arranged in an overlapping manner are securely connected. Can be connected.

In the connector according to the sixth aspect, since the hooking portion is hooked on the back side of the extending piece on both sides, the hooking force is increased, and the elastic contact portion provided at the tip end portion is hardly deformed. Further, the effect according to claim 5 can be further achieved in that the two substrates arranged in an overlapping manner can be reliably connected.
