Description

IDC connector

The present invention relates to a pressure contact connector for obtaining electrical continuity with electrodes of various electronic devices.

Patent Document 1 discloses a spring connector. Spring connectors are used for battery connectors and the like in mobile phones and other small electronic devices. The spring connector described in Patent Document 1 is a housing in which a contact urged by a coil spring is provided in a housing so as to freely advance and retract.

JP 2012-064549 A

The contact of the spring connector is provided so as to be able to advance and retract with respect to the housing in a state of being biased by a coil spring. For this reason, the contact moves in the forward / backward direction, but hardly moves in a direction different from the forward / backward direction. Therefore, when a force is applied in a direction different from the forward / backward direction (for example, in the lateral direction) while the contact is in contact with the other electrode, the contact and the electrode are rubbed, and the contact stability is caused by electrode corrosion. It will cause the decrease.

An object of the present invention is to provide a pressure contact connector capable of suppressing friction in a direction different from the advancing / retreating direction while ensuring a contact advancing / retreating stroke.

In order to solve the above problems, a press-connecting connector according to one aspect of the present invention includes a first cylindrical portion having a first contact portion, a main body portion slidable in a first direction with respect to the first cylindrical portion, and a main body A second cylinder part having a second contact part supported by the part, and an urging part for urging the first cylinder part and the second cylinder part in the first direction. In this pressure contact connector, the second contact portion is provided at an end portion of the main body portion, and is elastically supported by the main body portion so as to be displaced in a direction different from the first direction.

According to such a configuration, it is possible to ensure the stroke of the contact portion in the sliding range of the second tube portion with respect to the first tube portion. Further, since the second contact portion is elastically supported at the end portion of the main body portion (the end portion on the distal side with respect to the first tube portion), the second contact portion may be displaced in a direction different from the first direction. it can. Accordingly, when a force is applied in a direction different from the body direction (first direction), the second contact portion is elastically displaced with respect to the second cylindrical portion, and the contact portion, particularly the second contact portion. And the other electrode can be prevented from rubbing. The direction different from the first direction in which the second contact portion is displaced with respect to the second cylindrical portion includes not only a direction perpendicular to the first direction but also a direction inclined with respect to the first direction. .

In the above-described pressure contact connector, the elastic modulus in the direction different from the first direction in the second contact portion may be lower than the elastic modulus in the first direction. As a result, when a force is applied to the contact portion in a direction different from the first direction, the second contact portion can be easily moved in that direction, and the contact portion and the counterpart electrode can be prevented from being rubbed. it can.

In the above pressure contact connector, the elastic modulus in the first direction of the second contact portion may be higher than the elastic modulus in the first direction of the urging portion. In the press contact connector, the urging portion may be displaced in the first direction preferentially over the second contact portion. Thus, when a force is applied in the first direction between the first contact portion and the second contact portion, the first cylinder is moved before the second contact portion is displaced in the first direction with respect to the main body portion. The portion and the second tube portion slide in the first direction.

In the above pressure contact connector, at least one of the first contact portion and the second contact portion may have a winding portion provided in a spiral shape when viewed in the first direction. Thereby, the elastic modulus in the second direction orthogonal to the first direction can be made lower than the elastic modulus in the first direction at the winding portion. In particular, when the winding part is composed of a plate-like member having the first direction as the plate width direction and the second direction as the plate thickness direction (here, the plate-like member has a plate width larger than the plate thickness). When the force is applied to the contact portion in the second direction, the contact portion is easily displaced in the second direction without being inclined with respect to the first direction. Therefore, even when a force is applied to the contact portion in the second direction, the contact state between the contact portion and the electrode hardly changes.

In the above-described pressure contact connector, the winding part may have a plurality of spiral parts stacked in the first direction. Thereby, the movable range in the second direction can be sufficiently obtained while securing the stroke of the contact portion in the first direction.

In the above-described pressure contact connector, the winding portion may have a plurality of spiral portions juxtaposed in a second direction orthogonal to the first direction. Thereby, the amount of current passing through the winding portion can be increased.

In the case where the winding part has a plurality of spiral parts as described above, the plurality of spiral parts may be composed of the same member, that is, a single plate-like member. In this case, since the thickness of the plate-shaped member which comprises a some spiral part is equal, the uniformity of the characteristic of a spiral part can be improved.

In the above-described pressure contact connector, the first direction is a direction in which the second contact portion advances and retracts relative to the first contact portion. The urging portion is a coil spring that compresses and expands in the first direction. The first tube portion and the second tube portion are provided coaxially with one being an outer tube and the other being an inner tube. It may be incorporated coaxially inside the first cylinder part and the second cylinder part. Thereby, the movement in the second direction can be obtained while sufficiently securing the stroke of the contact portion by the compression and extension of the coil spring.

In the above-described pressure contact connector, the first tube portion has a first body portion that overlaps the second tube portion in a sliding range of the second tube portion when viewed in a second direction orthogonal to the first direction, The second body portion overlaps the first tube portion in the sliding range of the second tube portion as viewed in the second direction, and the movable amount in the second direction in at least one of the first contact portion and the second contact portion is The movable amount in the second direction in the first body part and the second body part may be larger. Thereby, even in the structure in which the contact portion is movable in the second direction, the sliding operation in the first direction can be smoothly performed in the trunk portion.

In the above pressure contact connector, a protrusion may be provided on at least one of the first contact portion and the second contact portion. Thereby, the contact shift | offset | difference of a contact part and the other party electrode can be suppressed.

In the above-described pressure contact connector, a spring wound from the main body portion may be extended and connected to the second contact portion, and a spherical protrusion may be provided so as to contact the back surface side of the second contact portion. As a result, when the second contact portion comes into contact with the counterpart electrode, the second contact portion comes into contact with each other in accordance with the inclination of the counterpart electrode.

In the pressure contact connector, a protrusion may be provided on the surface side of the second contact portion. Thereby, when the 2nd contact part contact | abuts the other party electrode, the contact shift | offset | difference of the other party electrode and the 2nd contact part can be suppressed.

In the above pressure contact connector, the second contact portion may be provided integrally with the urging portion. Thereby, a 2nd contact part and a biasing part can be formed from one material.

In the above-described pressure contact connector, the first tube portion may be connected to the urging portion within the tube. Thereby, the urging | biasing part can be fixed within the cylinder of a 1st cylinder part.

According to the present invention, it is possible to provide a pressure contact connector capable of suppressing friction in a direction different from the advancing / retreating direction while ensuring a contact advancing / retreating stroke.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same members are denoted by the same reference numerals, and the description of the members once described is omitted as appropriate.

(First embodiment)
FIG. 1 is a perspective view illustrating a pressure contact connector according to the first embodiment.
FIG. 2 is a cross-sectional view illustrating the pressure contact connector according to the first embodiment.
The press-connecting connector 1 according to the present embodiment is in contact with a mating electrode or wiring pattern to obtain electrical continuity. In the embodiment, an example in which electrical connection between the first electrode P1 and the second electrode P2 is obtained by the press-connecting connector 1 is shown.

The press-connecting connector 1 according to the present embodiment includes a first tube portion 10, a second tube portion 20, and an urging portion 30. The first tube portion 10 has a first contact portion 11 at an end portion (an end portion on the side distal to the second tube portion 20). The first cylindrical portion 10 is a member formed by, for example, beryllium copper or stainless steel plate material into a cylindrical shape by press working or the like. The extending direction of the cylindrical shape of the first cylindrical portion 10 is referred to as a first direction. The direction orthogonal to the first direction is referred to as the second direction. The first contact portion 11 is a portion that contacts (electrically conductive contact) with the first electrode P1.

The second cylinder part 20 has a second contact part 21 and a second body part (main body part) 22. The second contact portion 21 is provided at an end portion of the second body portion 22 (an end portion on the side distal to the first tube portion 10). Similarly to the first cylinder part 10, the second cylinder part 20 is formed into a cylindrical shape by pressing a plate material of beryllium copper or stainless steel, for example. The second contact portion 21 is a portion that contacts (electrically conductive contact) with the second electrode P2. Accordingly, in the pressure contact connector 1, the first contact portion 11 and the second contact portion 21 are located at both ends in the direction in which the first tube portion 10 and the second tube portion 20 extend, respectively.

A protrusion 215 may be provided at the tip of the second contact portion 21. Thereby, when the 2nd contact part 21 contacts the 2nd electrode P2, it can contact with the 2nd electrode P2 reliably by the projection part 215, and can suppress a contact shift.

The second cylinder part 20 is provided to be slidable in the first direction with respect to the first cylinder part 10. That is, the 1st cylinder part 10 and the 2nd cylinder part 20 are coaxially integrated by setting one side as an outer cylinder and the other as an inner cylinder. In the present embodiment, the first tube portion 10 is an outer tube, the second tube portion 20 is an inner tube, and the second tube portion 20 is inserted inside the first tube portion 10. Accordingly, the second contact portion 21 is provided so as to be able to advance and retract relative to the first contact portion 11 in the first direction.

The urging unit 30 urges the first cylinder part 10 and the second cylinder part 20 to each other in the first direction. In the present embodiment, a coil spring is used as the urging unit 30. The coil spring is incorporated coaxially with the inside of the first tube portion 10 and the second tube portion 20.

In order to prevent the second tube portion 20 from coming off from the first tube portion 10 in a state where the coil spring is incorporated, a hook portion 101 that is folded inward is provided on the edge of the first tube portion 10, and the second tube portion On the outer peripheral surface of 20, a convex portion 201 that hits the hook portion 101 is provided.

In such a pressure contact connector 1, the total length (length in the first direction) of the pressure contact connector 1 by the first tube portion 10 and the second tube portion 20 changes in accordance with the compression and extension of the coil spring. For example, when the 1st contact part 11 of the 1st cylinder part 10 is being fixed to the 1st electrode P1, the 2nd cylinder part 20 will be in the state which can advance / retreat with respect to the 1st cylinder part 10 in a 1st direction.

The second cylinder part 20 is urged by the urging part 30 in a direction away from the first cylinder part 10. The 2nd cylinder part 20 becomes a position (position where the full length is the longest) where it protrudes most in the state where convex part 201 and hook part 101 have hit.

When the distance between the second contact portion 21 of the second cylindrical portion 20 and the second electrode P2 approaches and the second contact portion 21 and the second electrode P2 come into contact with each other, the second cylindrical portion 20 moves toward the first cylindrical portion 10 side. Pushed in. As a result, the second contact portion 21 comes into pressure contact with the second electrode P2 by the biasing force of the biasing portion 30.

In the sliding range between the first tube portion 10 and the second tube portion 20, when viewed in the second direction, the portion of the first tube portion 10 that overlaps the second tube portion 20 is the first body portion 12, and the second portion. A portion of the tube portion 20 that overlaps the first tube portion 10 is a second body portion 22. A contact piece 13 is provided on the first body portion 12 of the first tube portion 10. The contact piece 13 is provided, for example, in a cantilever manner on the first body portion 12, and the tip is inwardly in contact with the outer peripheral surface of the second body portion 22. Thereby, electrical conduction between the first tube portion 10 and the second tube portion 20 is established.

In the pressure contact connector 1, the first contact portion 11 is in contact with the first electrode P 1, and the second contact portion 21 is in contact with the second electrode P 2, so that the first contact portion 11 is in contact with the first electrode portion P 2. Electrical conduction is established between the first electrode P1 and the second electrode P2. In order to reduce the contact resistance between the pressure contact connector 1 and the first electrode P1 and the second electrode P2, it is preferable that the first contact portion 11, the projection portion 215, and the contact piece 13 are plated with gold.

In such a pressure contact connector 1 according to the present embodiment, the elastic modulus in the second direction of the second contact portion 21 is provided lower than the elastic modulus in the first direction. Specifically, the second contact portion 21 is provided with a winding portion 210. The winding part 210 has a spiral part 210a provided in a spiral shape when viewed in the first direction. The winding part 210 is formed by winding a thin plate extending from the second body part 22 into a spiral shape. By providing such a winding part 210, the elastic modulus in the second direction of the second contact part 21 can be made lower than the elastic modulus in the first direction.

Therefore, when a force is applied to the second contact portion 21 in the second direction, the second contact portion 21 can be easily moved in the second direction. Thereby, even when a force is applied in the second direction while the second contact portion 21 and the second electrode P2 are in contact, the winding portion 210 of the second contact portion 21 moves in the second direction. , The rubbing of both in the second direction can be suppressed.

For example, even if vibration is applied in the second direction while the first electrode P1 and the second electrode P2 are electrically connected by the pressure contact connector 1, the second contact portion 21 follows the vibration and the second contact portion 21 is second. Will move in the direction. Thereby, the shift | offset | difference of the contact of the 2nd contact part 21 and the 2nd electrode P2 is suppressed.

Here, since the winding part 210 is formed by winding a thin plate (plate-like member) in a spiral shape, the thickness direction (plate thickness direction) of the thin plate becomes the second direction, and the width direction of the thin plate (plate width direction) ) Is the direction along the first direction. The plate width of the thin plate (plate member) constituting the winding part 210 is larger than the plate thickness. For example, the winding part 210 has a plate width of about 1.6 mm and a plate thickness of about 0.25 mm. Therefore, when vibration is applied in the second direction while the first electrode P1 and the second electrode P2 are electrically connected by the pressure contact connector 1, the second contact portion 21 is It can be displaced in the second direction without being tilted. Therefore, rubbing between the second contact portion 21 and the second electrode P2 hardly occurs, and the second contact portion 21 hardly damages the second electrode P2 in contact therewith.

On the other hand, when a force is applied to the second contact portion 21 in the first direction, the force is transmitted from the second contact portion 21 to the second trunk portion 22. As a result, the coil spring is compressed and the second cylinder part 20 is pushed into the first cylinder part 10.

The movable amount of the second contact portion 21 in the second direction is larger than the movable amount of the second body portion 22 in the second direction. Therefore, even if the second contact portion 21 has a structure that can move in the second direction, the amount of movement of the second body portion 22 in the second direction is small, and the sliding operation in the first direction can be performed smoothly. it can.

That is, in the second cylindrical portion 20, the second contact portion 21 in contact with the second electrode P2 is more easily movable in the second direction than the first direction, and the second trunk portion 22 that is a sliding portion is more movable than in the second direction. It is easy to move in the first direction. Thereby, in the press-connecting connector 1, the stroke by the sliding to the 1st direction of the 2nd cylinder part 20 is smoothed, suppressing the shift | offset | difference to the 2nd direction in the contact with the 2nd electrode P2 and the 2nd contact part 21. And it becomes a structure that can be secured sufficiently. In addition, since the displacement between the second contact portion 21 and the second electrode P2 is suppressed, the second electrode P2 can be prevented from being damaged by the protrusion 215 even when the protrusion 215 is in contact with the second electrode P2.

More specifically, as shown in FIG. 2, the first electrode P 1 and the second electrode P 2 are connected to each other via the press-connecting connector 1 and provided in the winding portion 210 of the second contact portion 21. The projected portion 215 is pressed with a relatively strong force by the biasing force of the biasing portion (for example, coil spring) 30. For this reason, when a vibration or light impact is applied, even if the second electrode P2 moves slightly in the first direction (for example, about 0.1 mm to 0.2 mm), it is pushed with a force that is almost the same as before the vibration. Since it continues, the contact location with the 2nd electrode P2 of the projection part 215 does not shift | deviate.

Even if the second electrode P2 moves slightly in the second direction (for example, about 0.1 mm to 0.2 mm), the winding portion 210 of the second contact portion 21 has a thickness direction smaller than the plate width. Is in the second direction, the contact location of the protrusion 215 does not change due to the frictional force pressing the protrusion 215 against the second electrode P2. Therefore, it can easily move (follow) in the second direction in accordance with the movement of the second electrode P2. Therefore, no friction is generated between the second electrode P2 and the second contact portion, so that contact stability is maintained.

Note that the elastic modulus in the first direction of the second contact portion 21 is set higher than the elastic modulus in the first direction of the urging portion 30. With this setting, when an external force that compresses in the first direction is applied to the press-connecting connector 1, the biasing portion 30 preferentially contracts in the first direction. For this reason, the second contact portion 21 can reduce the amount of deformation in the first direction due to this external force. If the second contact portion 21 is greatly elastically deformed in the first direction, the second contact portion 21 may not be appropriately elastically deformed in the second direction. In such a case, when an external force in the second direction is applied to the pressure contact connector 1, it is difficult to absorb the external force due to elastic deformation of the second contact portion 21. Therefore, it is preferable that the elastic modulus in the first direction of the second contact portion 21 is set higher than the elastic modulus in the first direction of the urging portion 30 as described above.

(Second Embodiment)
FIG. 3 is a perspective view illustrating a pressure contact connector according to the second embodiment.
FIG. 4A is a front view illustrating a pressure contact connector according to the second embodiment, and FIG. 4B is an enlarged perspective view of a second contact portion.
In the pressure contact connector 1B according to the present embodiment, the configuration of the winding part 210 is different from that of the pressure contact connector 1 according to the first embodiment.
That is, the winding part 210 provided in the 2nd contact part 21 of the press-contact connector 1B has the several spiral part 210a piled up in the 1st direction. In the example shown in FIGS. 3 and 4, two spiral portions 210 a are overlapped in the first direction.

By providing the two spiral portions 210a so as to overlap in the first direction, the movable range of the second contact portion 21 in the second direction can be sufficiently obtained. Moreover, the full length of the press contact connector 1B can be lengthened, ensuring the stroke of the 2nd cylinder part 20 to the 1st direction.

When the winding part includes a plurality of spiral parts as in the present embodiment, it may be preferable that the plurality of spiral parts are made of the same member. Taking the case where the winding part is composed of a plate-like member as a specific example, the thickness of the plurality of spiral parts becomes equal by being formed from the same member, and the uniformity of the characteristics of the spiral part such as the elastic modulus is improved. .

In the example shown in FIGS. 5 and 6, two spiral portions 210 a are juxtaposed in the second direction.

The two spiral portions 210a are juxtaposed in the second direction, so that the cross-sectional area of the second contact portion 21 viewed in the first direction increases, and the amount of current passing through the winding portion 210 can be increased.

In the example shown in FIGS. 5 and 6, two spiral portions 210a are juxtaposed in the second direction and two spiral portions 210a are overlapped in the first direction. Thereby, the movable range in the second direction of the second contact portion 21 can be sufficiently obtained.

In the example shown in FIG. 5 and FIG. 6, four spiral portions 210a are arranged in 2 × 2 in the second direction. Thereby, the cross-sectional area seen in the 1st direction of the 2nd contact part 21 increases compared with 1C of press-connecting connectors of 3rd Embodiment, and the amount of electric currents which pass the winding part 210 can further be increased.

In the example shown in FIGS. 7 and 8, four spiral portions 210a are arranged in the second direction, and two spiral portions 210a are overlapped in the first direction. Thereby, the movable range in the second direction of the second contact portion 21 can be sufficiently obtained.

A protrusion 115 is provided at the tip of the first contact portion 11, and contact displacement with the first electrode P1 can be suppressed.

In the example shown in FIG. 9, the winding portion 210 of the second contact portion 21 and the winding portion 110 of the first contact portion 11 are overlapped in the first direction similar to the pressure contact connector 1B according to the second embodiment. There are two spiral portions 210a. The winding unit 210 and the winding unit 110 may have a configuration other than the second embodiment.

In the pressure contact connector 1E, it is applied as a connector of a type that is in pressure contact with the counterpart electrode in both the first contact portion 11 and the second contact portion 21. As described above, the winding portion 210 is provided in the second contact portion 21 and the winding portion 110 is provided in the first contact portion 11, whereby the second contact portion 21 and the second electrode P 2 are moved in the second direction. The shift in the second direction between the first contact portion 11 and the first electrode P1 can be suppressed.

(Sixth embodiment)
FIG. 10 is a perspective view illustrating a pressure contact connector according to the sixth embodiment.
In the pressure contact connector 1F according to the present embodiment, the second contact portion 21 is elastically supported by the second body portion 22 so that the second contact portion 21 can be displaced in a direction different from the first direction.
That is, a movable piece 213 is provided at the tip of the second contact portion 21, and this movable piece 213 extends from the end of the spiral portion 210 a that is a wound spring, and is cantilevered by this end. It is supported in the shape. The movable piece 213 may be provided with a protrusion 215. The movable piece 213 can be displaced in a direction different from the first direction.

A spherical protrusion 217 is arranged on the back side of the movable piece 213. The spherical protrusion 217 is provided in a hemispherical shape that is convex toward the movable piece 213, and comes into contact with the back surface of the movable piece 213. When the back surface of the movable piece 213 comes into contact with the spherical protrusion 217, the movable piece 213 can be displaced so as to be inclined along the surface of the spherical protrusion 217.

FIGS. 11A and 11B are schematic views illustrating the movement of the movable piece.
When the movable piece 213 comes into contact with the inclined second electrode P2, the movable piece 213 is displaced to be inclined in accordance with the inclination of the second electrode P2. Since the movable piece 213 can be tilted in accordance with the surface (curved surface) of the spherical protrusion 217 provided on the back side of the movable piece 213, the movable piece 213 is movable between the inclined second electrode P2 and the spherical protrusion 217. When the piece 213 is sandwiched, the movable piece 213 follows the inclination of the second electrode P2 and comes into contact with the inclination.

For example, as shown in FIG. 11A, when the second electrode P2 is inclined to the left, the movable piece 213 is inclined to the left along the spherical protrusion 217, and as shown in FIG. When the second electrode P2 is tilted to the right, the movable piece 213 is tilted to the right along the spherical protrusion 217. That is, the movable piece 213 is inclined with the spherical protrusion 217 as a support. As a result, even when the second electrode P2 is inclined, the movable piece 213 is inclined following the inclination, and contact displacement can be suppressed and conduction can be reliably obtained.

(Seventh embodiment)
FIG. 12 is a perspective view illustrating a pressure contact connector according to the seventh embodiment.

In the pressure contact connector 1G, the second cylindrical portion 20 and the urging portion 30 are formed from a single metal plate material. That is, the second cylinder portion 20 and the urging portion 30 are configured as one component by bending a single metal plate material. For example, the winding piece 210 and the movable piece 213 are configured on one side by bending the extending piece of the metal plate material in a spiral shape, and the biasing portion 30 is configured on the other side. Thereby, an integrated three-dimensional structure in which the winding part 210 and the urging part 30 are arranged to overlap in the first direction is configured. This three-dimensional structure has the functions of the second cylindrical portion 20 and the urging portion 30.

In any of the embodiments described above, the first tube portion 10 may be connected to the biasing portion 30 in the tube. For example, the lower end of the urging portion 30 is fixed to the inner bottom of the first tube portion 10 by laser welding or the like. Thereby, the urging | biasing part 30 and the 1st cylinder part 10 can be connected firmly.
