Description
Technical Field
The present invention relates to a contact used for connection between a substrate and an electric wire or the like, and a connector using the contact.
Background
In the past, so-called card edge connectors have been used for connecting a substrate to an electric wire or the like (see, for example, patent document 1).
The card edge connector includes a housing having a connection object insertion portion into which an end portion of a substrate is inserted, and a plurality of contacts held in the housing so that contact portions project into the connection object insertion portion, and when the end portion of the substrate is inserted into the connection object insertion portion, the contacts come into contact with a substrate connection terminal disposed at the end portion of the substrate with a predetermined contact pressure, thereby electrically connecting the substrate and an electric wire or the like via the contacts.
In the conventional card edge connector, a contact having a cantilever spring-like elastic contact piece whose tip end side extends and protrudes in an insertion direction is generally used, and when insertion of the board end portion is started, the contact comes into contact with the board, and from this state, the board and the contact are inserted to a predetermined position in a mutually sliding manner, and the board end portion surface is cut by the contact, and the chips thereof are attached between the board connection terminal and the contact, thereby possibly causing a conduction failure.
Further, when the substrate is inserted, the contact portion of the contact is slid by a predetermined distance in a state of being in contact with the substrate connection terminal in consideration of dimensional tolerance and backlash, and thus, there is a problem that the substrate connection terminal is worn when the substrate is repeatedly attached and detached.
Therefore, as shown in fig. 7, the following apparatus has also been developed: the contact 9 used in such a card edge connector includes an operation contact portion 91 disposed on the rear side in the board insertion direction, and a main contact portion 92 disposed on the front side of the operation contact portion 91 and at a position distant from the board B or at a position where a contact pressure is not substantially generated, and the board edge contacts the operation contact portion 91, and the main contact portion 92 moves toward the board B side by the operation contact portion 91 being pressed down, and contacts the board connection terminal with a predetermined contact pressure.
When the contact 9 is used, the board end does not contact the contact 9 in the initial stage of insertion of the board B, or the contact pressure is small even in the contact, so that cutting of the board B and abrasion of the board connection terminal caused by sliding between the board B and the contact 9 can be suppressed.
Documents of the prior art
Patent document 1: japanese patent No. 5922295
However, in the above-described conventional technique, in consideration of looseness and tolerance at the time of fitting, the contact portion for operation needs to slide a certain distance with respect to the substrate end surface, and the main contact portion needs to slide a certain distance with respect to the substrate connection terminal, so that there is no possibility that the substrate end surface is cut by both contact portions, and the cutting debris becomes a cause of conduction failure.

As shown in fig. 1, the housing 1 is formed in a rectangular parallelepiped shape by an insulating resin, and a connection object insertion portion 11 having a slit hole shape is opened on the front surface side thereof so as to match the shape of the substrate B as a connection object.
In the housing 1, contact insertion grooves (not shown) are formed along the inner side surface of the connection object insertion portion 11, and the contacts 2 and 2 are inserted into the contact insertion grooves from the rear surface side of the housing 1.
As shown in fig. 2 and 3, the contact 2 is integrally formed by punching and bending a conductive metal plate material, and includes an elastic contact piece 3 which comes into contact with a substrate B as a connection object which slides relative to each other at a desired connection position, and a support plate portion 4 which supports the elastic contact piece 3.
The contact 2 further includes: a press-in contact portion 52 that contacts the substrate B inserted into the housing 1; a movable guide 53 that slides relative to the elastic contact piece 3 in conjunction with the movement of the pushing contact portion 52; and an operation elastic body 51 for supporting the movable guide 53 in an elastically deformable state in the insertion and extraction direction of the substrate B, and the movable guide 53 slides in conjunction with the substrate B as the target link.
The movable guide 53 is provided with a contact restricting portion 81 that presses the elastic contact piece 3 in a direction away from the connection object, the substrate B of the connection object is brought into contact with the press-in abutting portion 52, and the movable guide 53 is moved in the connection object insertion direction, whereby the elastic contact piece 3 is released from the contact restricting portion 81 and comes into contact with the substrate B as the connection object at a desired connection position.
The contacts 2 and 2 are provided with fixed guide portions 6 that rise from side edges of the support plate portions 4 and are disposed on the sides of the elastic contact pieces 3.
The support plate portion 4 is formed in a plate shape disposed parallel to the substrate B, integrally supports the base end of the elastic contact piece 3 at one end thereof, and integrally forms a connection terminal portion 7 for pressure-welding the electric wire C at the other end side. The form of the connection terminal portion 7 is not limited to the present embodiment, and is appropriately changed according to the form of the target to be connected.
The elastic contact piece 3 includes an elongated plate-shaped base-side elastic piece portion 31 extending and protruding in an oblique direction from one end of the support plate portion 4, and a distal-side elastic piece portion 33 continuous with the base-side elastic piece portion 31 and having an arc-shaped contact portion 32 integrally formed at a distal end thereof, and the contact portion 32 side is lifted up and is formed in a cantilever spring shape capable of flexing in a direction away from the substrate B.
The elastic contact piece 3 integrally includes guide projecting pieces 34, 34 projecting outward from the side edge thereof, i.e., the side edge of the base-end elastic piece portion 31.
The contact 2 includes a movable guide support portion 54 rising from one side edge of the support plate portion 4, the operation elastic body 51 is supported at an edge portion of the movable guide support portion 54, and the movable guide 53 is disposed on the side of the elastic contact piece 3 with its short side direction directed upward and downward via the movable guide support portion 54 and the operation elastic body 51.
As shown in fig. 3 (a), one end of the operation elastic body 51 is integrally supported by a side edge of the movable piece base point portion 54, is formed in a chevron shape or an arc shape in a plan view, can be bent in the substrate insertion direction, and can be deformed in the insertion and extraction direction of the connection object.
Further, a press-fit abutting portion 52 is integrally formed continuously on the operation elastic body 51 on the substrate B side, and when the substrate B as a connection object comes into contact with the press-fit abutting portion 52, the operation elastic body 51 is pressed and deformed by the press-fit convex portion 52.
The pushing contact portion 52 is disposed outside the side edge of the substrate of the movable guide 53 and protrudes into the object insertion portion 51 of the housing 1.
The movable guide 53 is formed in a rectangular plate shape, and the inner end in the substrate insertion direction is integrally supported by the operation elastic body 51, and is slidably supported by the support plate portion 4 via the operation elastic body 51 and the movable guide support portion 54.
That is, the movable guide 53 slides in the insertion/removal direction of the substrate B relative to the elastic contact piece 3 supported by the support plate portion 4 in conjunction with the deformation (flexure) of the operation elastic body 51.
The movable guide 53 is formed with a guide notch 8 into which the guide tabs 34, 34 are inserted, and the guide tabs 34, 34 are guided along the guide notch 8.
As shown in fig. 3 (c), a contact restricting portion 81 is formed on the back side of the inner edge of the guide notch portion 8 on the substrate B side in the substrate insertion direction, and a release concave portion 82 recessed toward the substrate B side is formed on the front side thereof continuously with the contact restricting portion 81, and the inner edge of the substrate B side is stepped.
The relative positions of the guide tabs 34, 34 with respect to the guide notch portion 8 are switched between the contact restricting portion 81 and the release recessed portion 82 in accordance with the sliding movement of the movable guide 53.
That is, when the board B is not inserted, the contact restricting portion 81 is positioned on the extraction side (initial position) of the board B in a state of being supported by the operation elastic body 51, and the contact restricting portion 81 engages with the guide lug 34, and when the board B is inserted, the movable guide 53 moves in conjunction therewith, and the guide lug 34 moves relatively toward the release recess 82 side.
The contact restricting portion 81 is formed at a position separated from the side edge of the board B of the movable guide 53 by a predetermined distance L1, and presses the guide projecting pieces 34 and 34 in the direction away from the board B in accordance with the distance L1 to flex the elastic contact piece 3 until the contact portion 32 is located at a position inside the side edge of the board B of the movable guide 53, that is, at a position not in contact with the board B.
The releasing recess 82 includes a guiding inclined portion 83 at an inner edge on the side close to the contact regulating portion 81, and the guiding projecting piece 34 is guided by the guiding inclined portion 83 to move relatively between the contact regulating portion 81 and the releasing recess 82.
Further, the distance L2 between the inner edge of the releasing recess 82 on the board B side and the side edge of the movable guide 53 on the board B side is short, and the guide projecting pieces 34 and 34 are released from the contact regulating portion 81 by moving toward the releasing recess 82 side, so that the elastic contact piece 3 is elastically restored, and the contact point portion 32 projects outward beyond the side edge of the movable guide 53 on the board B side.
As shown in fig. 3 (b), the fixed guide portion 6 is formed in a rectangular plate shape rising from the other side edge of the support plate portion 4, is arranged on the side of the elastic contact piece 3, and is opposed to the movable guide 53 with the elastic contact piece 3 interposed therebetween.
The fixed guide portion 6 is formed with an avoidance notch 61 into which the guide tabs 34, 34 are inserted.
In the connector a using the contacts 2 and 2, when the board B is not inserted, the movable guide 53 is in the initial position, the guide tabs 34 and 34 are pressed by the contact restricting portion 81, and the elastic contact piece 3 is in a state of being deflected in a direction away from the board B, that is, a pre-loaded state.
In this preloaded state, the contact portion 32 of the elastic contact piece 3 is located inside the side edge of the substrate B of the movable guide 53.
On the other hand, when the board B is inserted into the connection object insertion portion 11, as shown in fig. 4, the board B is still in the preloaded state before the board B comes into contact with the pushing contact portion 52 in the initial stage of insertion, and the elastic contact piece 3 does not come into contact with the surface of the board B, and the board B and the contact 2 do not slide.
When the substrate B is further inserted, as shown in fig. 5, the front end edge of the substrate B in the insertion direction comes into contact with the pushing contact portion 52, the pushing contact portion 52 is pushed by the substrate B, the operation elastic body 51 flexes in the sliding direction and the connecting object insertion/removal direction in conjunction with this, and the movable guide 53 starts moving to the back side in the insertion direction in parallel with the insertion of the substrate B.
As shown in fig. 6, when the substrate B is inserted to a predetermined position, the movable guide 53 is further moved to the back side, the positions of the guide projecting pieces 34 and 34 are guided by the guide inclined portion 83 and relatively moved to the position of the release concave portion 82, and the elastic contact piece 3 is released from the contact regulating portion 81.
The elastic contact piece 3 released from the contact regulating portion 81 elastically returns from a deflected state (pre-loaded state), and the contact portion 32 at the tip moves toward the substrate B side and comes into contact with the substrate connection terminal on the surface of the substrate B at a predetermined contact pressure.
In the connector a using the contacts 2 and 2, when the board B is pulled out from the connection object insertion portion 11, the force acting on the pushing contact portion 52 is removed, the operation elastic body 51 elastically returns from the deflected state, and the movable guide 53 is urged by the operation elastic body 51 to return to the initial position shown in fig. 4.
At this time, the guide projecting pieces 34 and 34 are guided by the guide inclined portion 83 and relatively move to the position of the contact regulating portion 81, the guide projecting pieces 34 and 34 are pressed by the contact regulating portion 81, and the elastic contact piece 3 is deflected in a direction away from the substrate B, and is restored to the initial state.
In the connector a configured as described above, the sliding between the board B and the contact 2 during the insertion and removal of the board can be suppressed, and the generation of chips and the abrasion of the board surface due to the sliding can be prevented.
In the connector a, the press-fitting abutting portion 52 is in contact with the substrate B when the substrate is inserted and removed, but the substrate B and the press-fitting abutting portion 52 do not slide with each other, and thus chips are not generated along with the sliding and the abrasion of the substrate surface is not generated.
In the above-described embodiment, the example in which the pushing abutment portion 52 is formed integrally with the operation elastic body 51 has been described, but the pushing abutment portion 52 may be provided so as to protrude from the side edge of the substrate B of the movable guide 53.
In the above-described embodiment, the example in which the contacts 2 and 2 are integrally formed by punching and bending a conductive metal plate material has been described, but the operation elastic bodies 51 may be provided separately and may be interposed between the movable guide support portion 54 and the movable guide 53.

In the above-described embodiment, the example in which the contact regulating portion 81 is formed at the side edge of the substrate B of the guide notch portion 8 formed in the movable guide 53 has been described, but the form of the contact regulating portion 81 is not limited to this, and for example, a part of the movable guide 53 may be formed by being bent inward or cut.
