However, the connector described in Patent Document 1 has a cross section that intersects the elastic direction of the spring, and the spring is connected to only one piece of the upper flat plate portion 1a. In addition, the spring portions facing each other have different elasticity due to different plate widths . Therefore, when a load is applied in the vertical direction, the upper flat plate portion 1a is displaced in a state inclined conventionally in the vertical direction, and thus there is a possibility that the electrical contact is unstable.

Moreover, since the spring portions are displaced while being inclined, the spring portions may slide against each other, and there is a possibility that foreign matter caused by grinding may occur or the spring portions interfere with each other to plastically deform.

The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to provide a connector that can stabilize electrical contact and ensure contact load, and a connector using the connector.

Therefore, electrical contact can be stabilized at the contact portion.

In the connector described above, the first spring portion and the second spring portion may be configured to have at least one bent portion that is bent in a vertical plane and folded back in the middle.

With this structure, the first spring portion and the second spring portion have a bent portion that bends back and forth in a vertical plane in the middle, so that the stroke can be lengthened and sufficient contact for stable electrical contact is ensured. Weight bearing.

In the connector described above, the first spring portion and the second spring portion may be configured to have at least one bent portion that bends in a horizontal plane in the middle.

Within the width.

According to this structure, the upper surface of the housing overlaps with the highest position among the spring pieces of the first spring portion and the second spring portion, so that the connector can be prevented from being overlaid on the housing when the connector is compressed. Conditions where the surface causes deformation of the connection.

In the above-mentioned connector, the case may be configured to be surrounded by a wall surface constituting the case body and have an opening surface that opens up and down in a vertical direction, and the contact portion and the first spring portion and the second spring may be configured. The part is a size accommodated in the opening surface in a plan view.

According to this structure, the connector is configured to be housed in the opening surface of the housing in a plan view, so that interference with the housing can be prevented when the connector is elastically deformed in the vertical direction, and the durability of the connector can be improved.

According to this structure, since the first spring portion 12 and the second spring portion 13 have the same shape, and are provided with point symmetry with respect to the center of the contact portion 11, that is, the central convex portion 11A, the vertical direction of the contact portion 11 is applied. When a weight is applied, the first spring portion 12 and the second spring portion 13 are not displaced obliquely with respect to the vertical direction. Therefore, the electrical contact can be stabilized at the contact portion 11. In addition, it is possible to prevent the first spring portion 12 and the second spring portion 13 from sliding due to displacement of the first spring portion 12 and the second spring portion 13 while being inclined, and the occurrence of foreign matter caused by grinding or the spring portion can be avoided. Interference and plastic deformation.

According to this structure, the first spring portion 12 and the second spring portion 13 have the spring piece 12B, the spring piece 12D, the spring piece 13B, and the spring piece 13D which are inclined with respect to the horizontal plane in the middle. Therefore, when elastically deformed in the vertical direction, It is possible to avoid interference with the upper or lower case 20, the external substrate 30, and the like.

The connector 1 of this embodiment includes a connector 10 and a housing 20, and the housing 10 is a housing body composed of an outer wall surface 20A, an upper surface 20B, a lower surface 20C, and an inner wall surface 20D. And a storage space S for housing the connector 10.

According to this structure, since the connector 10 is accommodated in the storage space S of the housing 20, interference between the connector 10 and the outside can be avoided, and the durability of the connector 1 can be improved.

Moreover, in the connector 1, the housing 20 is configured such that the vertical height of the upper surface 20B is located at the highest position among the plurality of spring pieces constituting the first spring portion 12 and the second spring portion 13 and is housed in the spring. The width of the sheet 12A and the spring sheet 13A in the vertical direction is within the range.

According to this structure, since the upper surface of the housing 20 and the spring pieces 12A and 13A at the highest position among the spring pieces of the first spring portion 12 and the second spring portion 13 overlap, the connection piece 10 is It is possible to prevent the connecting member 10 from being deformed when the connecting member 10 overlaps the upper surface 20B of the housing 20 during compression.

Moreover, in the connector 1, the housing 20 is configured to be surrounded by an outer wall surface 20A, an upper surface 20B, a lower surface 20C, and an inner wall surface 20D constituting the housing body, and is surrounded by the vertical direction. The upper opening surface 21A and the lower opening surface 21B, which are opened vertically, and the contact portion 11 and the first spring portion 12 and the second spring portion 13 are housed in the upper opening surface 21A (or the lower opening surface 21B) in a plan view. the size of.

According to this structure, the connector 10 is configured to be housed in the upper opening surface 21A (or the lower opening surface 21B) of the housing 20 in a plan view, so that the connector 10 can be prevented from being deformed with the housing 20 when it is elastically deformed in the vertical direction. Interference can improve the durability of the connector 1.

Further, in the connector 1, the first joint portion 14 and the second joint portion 15 have first protruding pieces 14A, 14B, and a second protruding piece 15A that protrude outward from the lower opening surface 21B in the horizontal direction with respect to the housing body. , 15B.

According to this structure, the area of the bonding portion when the first bonding portion 14 and the second bonding portion 15 are solder-connected to the external substrate 30 can be increased, so that the bonding strength between the connector 1 and the external substrate 30 can be improved.

As described above, the connector and the connector of the present invention have the effects of stabilizing electrical contact and ensuring contact load, and are useful for the connector and the entire connector.
