Abstract

A connector where, without causing a connector body and a terminal to be larger in size, the amount of terminal displacement in a direction perpendicular to a direction of contact of the terminal with an object to which the connector is connected can be reduced and contact pressure between the terminal and the object can be increased. A terminal (20) is formed in a substantially letter S shape, so that it can be deformed around a second bend portion (24), located at a short distance (C2) from a contact portion (26), as a base point. Therefore, a displacement amount (B) of the contact portion (26) in a direction (direction Y) perpendicular to a contact direction (direction X) of an object to which the connector is connected can be reduced without causing a connector body (10) and the terminal (20) to be larger in size. Because one end side of a terminal (20) is made short in direction Y so as not to enter the range where a top end portion (28) displaced in direction X is movable, a displacement amount (A) in direction X of the contact portion (26) can be made larger.

Description

Description Connector Technical field

The present invention relates to a connector for electrically connecting, for example, a rechargeable battery for a mobile phone to a mobile phone main body. Background art

In general, a battery made of a rechargeable battery is detachably mounted on the back side of the main body of the mobile phone. The main body of the mobile phone is electrically connected via a connector (for example, see Japanese Patent Publication No. 9-36941).

The connector includes a plurality of elastically deformable terminals that come into contact with a connection object such as a battery, and an insulative connector main body that holds each terminal, and fixes one end of each terminal in the connector main body. At the same time, the other end of each terminal is protruded from the one end of the connector body to the outside, and the object to be connected is brought into contact with the other end of the terminal from a predetermined direction of the connector body, thereby connecting each terminal to the connector body. It is configured to be elastically deformed so as to be pressed against the electric contact of the object to be connected (for example, see Japanese Patent Application Publication No. 2002-175584).

By the way, in the connector, it is necessary to increase the amount of deformation of the terminal in order to increase the contact pressure of the terminal with the object to be connected. In this case, however, the displacement of the contact portion due to the deformation of the terminal becomes a problem.

For example, as in the first conventional example shown in FIG. 3, when one end is formed in a substantially rectangular shape with the other end of the terminal 2 fixed in the connector main body 1 with respect to the one end, The other end of the terminal 2 is displaced in the X direction and the Y direction in the figure with the bent portion 2a between the terminal 2 and the one end as a base point, as indicated by the dot-dash line. In this case, since the bent portion 2a is located on the other end side of the connector body 1, the distance C between the contact portion 2b of the terminal 2 located on one end side of the connector body 1 becomes longer, and the X direction of the terminal 2 ( Displacement A in the direction of contact of the connection object) is large The displacement き of the contact portion 2 b in the Y direction perpendicular to the X direction also increases. Therefore, in order to obtain a high contact pressure, a large contact area is required on the connection object side to allow the amount of displacement B of the terminal 2 in the Y direction. There was a problem that it was not possible.

In addition, as in the second conventional example shown in FIG. 4, when the amount of displacement A of the terminal 2 in the X direction is reduced by reducing the amount of protrusion of the terminal 2 from the connector body 1, Although the displacement B of the contact portion 2b is also small, the contact pressure with the object to be connected is reduced by that amount, and the contact failure is likely to occur.

Therefore, as in the third conventional example shown in FIG. 5, the height dimension H of the connector body 3 is increased and the dimension L from the bent portion 4a to the contact portion 4b of the terminal 4 is increased. The curvature of the trajectory of the contact portion 4b centered on the bent portion 4a is reduced, and the displacement amount B of the contact portion 4b in the Y direction with respect to the displacement amount A of the terminal 4 in the X direction can be reduced. . However, in this case, there is a problem that the connector main body 3 and the terminals 4 are increased in size as the height of the connector main body 3 is increased.

Also, as in the fourth conventional example shown in FIGS. 6A and 6B, a terminal 5 having one end fixed to the connector body 1 is formed in a substantially S-shape to form a total of two bent portions 5a and 5a. In the case where b is provided, as shown in FIG. 6A, the terminal 5 is deformed with one bent portion 5a located closer to the other end by a distance C1 from one end thereof as a base point. The distance C2 from the base point (the bent portion 5a) to the contact portion 5c is reduced, and the displacement B in the Y direction of the contact portion 5c can be reduced. However, when the terminal 5 is formed in a substantially S-shape as described above, when the object to be connected contacts obliquely with respect to the X direction, for example, as shown by the dashed line or broken line in FIG. The end side tends to be greatly deformed in the Y direction. For this reason, the terminal 5 may be displaced by the displacement amount B 1 or B 2 in the Y direction, and the displacement amount of the contact portion 5c cannot always be reduced.

Therefore, as in the fifth conventional example shown in FIG. 7, a total of two bent portions 6a and 6b are provided on the terminal 6 formed in a substantially S shape, and one of the bent portions 6a and If the length L up to c is long, even if the object to be connected comes into contact obliquely, the terminal 6 will not be greatly deformed in the Y direction, and the displacement B of the contact portion 6c will be substantially reduced. It can be within a certain small range. However, terminal 6 is formed in a substantially S shape In this case, the tip 6 d of the other end of the terminal 6 contacts the straight portion 6 e extending from the one bent portion 6 a to the other bent portion 6 b of the terminal 6, and the X There was a problem that the amount of displacement A in the direction could not be increased.

The present invention has been made in view of the above-described problems, and has as its object to displace a terminal in a direction orthogonal to a contact direction of a connection object without increasing the size of the connector body and the terminal. An object of the present invention is to provide a connector that can reduce the amount and can increase the contact pressure with an object to be connected. Disclosure of the invention

In order to achieve the above object, the present invention includes an elastically deformable terminal that comes into contact with an object to be connected, and an insulative connector body that holds the terminal, and fixes one end of the terminal in the connector body. The terminal is elastically deformed to the connector body side by projecting the other end of the terminal from the one end side of the connector body to the outside, and bringing the connection object into contact with the other end of the terminal from a predetermined direction of the connector body. In the connector, the terminal is formed such that the other end is deformed in the contact direction of the object to be connected from a portion located at a predetermined distance from the one end toward the other end, and the terminal is connected to one end of the terminal. Is formed so as to avoid the movable range of the distal end on the other end side displaced in the contact direction of the connection target.

As a result, the other end of the terminal is deformed from the one end located a predetermined distance closer to the other end as a base point, so that the distance from the base point of deformation to the tip end is reduced by that much, and contact of the connection target is reduced. The amount of displacement of the distal end portion in the direction orthogonal to the direction becomes smaller. In this case, one end of the terminal is formed so as to avoid the movable range of the tip of the other end, so that the tip of the other end of the terminal does not interfere with the one end and extends deep into the connector body. The terminal is displaced, and the amount of displacement of the terminal in the contact direction of the connection target increases. ADVANTAGE OF THE INVENTION According to the connector of this invention, the amount of displacement of the terminal in the direction orthogonal to the contact direction of the object to be connected can be reduced without increasing the size of the connector body and the terminal, and the contact pressure with the object to be connected can be reduced. The connection between the connector and the object with a small contact, such as a battery with a concave contact, such as a small battery for a mobile phone, may cause a poor connection. Without fail. Also, since the connector body and terminals do not become large, This is extremely advantageous when used in small electronic devices with a small space for mounting the connector.

1 and 2 show one embodiment of the present invention.

This connector includes an insulating connector body 10 and a plurality of terminals 20 held by the connector body 10 so that each terminal 20 contacts a battery (not shown) as a connection object. It has become.

The connector main body 10 is made of a synthetic resin molded product, and has a plurality of terminal holes 11 in which the terminals 20 are arranged at intervals in the width direction. Each terminal hole 11 is open on the front (one end surface) and the lower surface of the connector body 10, and the upper and rear sides (the other end surface of the connector body 10) are on the connector body 10. 0 is surrounded by a top wall 12 and a back wall 13. A plurality of protrusions 14 are provided on the lower part of the front surface of the connector body 10 so as to protrude forward from between the respective terminal holes 11. On the lower surface of each protrusion 14, protrusions 1 for positioning on a substrate or the like are provided. 4a is provided for each. Further, a terminal holding portion 15 extending vertically along the rear wall 13 is provided in the connector body 10, and although not shown, the terminal holding portions 15 are spaced from each other in the width direction of the terminal hole 11. It is provided so as to face each other. That is, the terminal 20 is held by the connector main body 10 by press-fitting one end of the terminal 20 between the terminal holding portions 15 from below. In this case, the upper end side of the terminal holder 15 is formed lower than the upper wall 12, so that the tip of the terminal 20 is located between the upper end of the terminal holder 15 and the upper wall 12. A receiving space 16 is formed.

Each terminal 20 is formed of an elastically deformable conductive metal plate partially formed in an S-shape, and one end thereof is fixed to the connector main body 10. The terminal 20 includes a first straight portion 21 extending vertically along the back wall 13 of the connector body 10 and a first straight portion bent downward from an upper end of the first straight portion 21. A bent portion 22, a second straight portion 23 extending downward from the first bent portion 22, and a second bent portion 24 bent obliquely upward from the lower end of the second straight portion 23 And a third straight portion 25 extending outward from the second bent portion 24 through the front surface of the connector main body 10, and bent so as to project forward from an upper end of the third straight portion 25. A contact portion 26, a fourth straight portion 27 extending rearward from the contact portion 26, and a front end portion 28 formed by bending the rear end of the fourth straight portion 27 downward. ing. The length of the first straight portion 21 is shorter than that of the conventional example shown in FIG. 7, so that the first bent portion 22 is located below the space 16. That is, the terminal 20 contacts the object to be connected with the second bent portion 24 located at the other end of the terminal 20 as a base point, of the bent portions 22 and 24 of the substantially S-shaped portion. The first bent part 22 located at one end of the terminal 20 is formed outside the movable range of the tip part 28 at the other end.

A connection portion 29 connected to a substrate or the like is provided at one end of the terminal 20, and the connection portion 29 extends from the lower end of the first straight portion 21 to the front of the connector body 10. Is formed. Further, the distal end 28 side of the terminal 20 is arranged so as to be close to the upper wall 12 of the connector main body 10.

The connector configured as described above is attached to, for example, a board of a battery storage section of a mobile phone. That is, when a battery (not shown) as an object to be connected comes into contact with the contact portion 26 of the terminal 20, the terminal 20 is deformed in the X direction as shown by a dashed line in FIG. At this time, the other end of the terminal 20 is deformed with the second bent portion 24 located at a distance C 1 closer to the other end from the first straight portion 21 of the one end as a base point. The distance C2 from the base point of deformation (the second bent portion 24) to the contact portion 26 is reduced by that much, and the displacement B of the contact portion 26 in the Y direction is reduced. Further, the terminal 20 can be displaced to a position where the tip portion 28 is received in the space 16 in the terminal hole 11. That is, since one end of the terminal 20 is formed so that the first bent portion 22 avoids the movable range of the distal end portion 28 of the terminal 20, the distal end portion 28 of the terminal 20 is in the second position. Of the terminal hole 11 without interfering with the straight portion 23 of the second straight portion 23, and can be displaced to the rear of the second straight portion 23 by the displacement amount A '. As a result, the displacement A of the terminal 20 in the X direction is increased by the displacement as compared with the conventional example of FIG. Further, when the terminal 20 is deformed in the X direction, the upper end thereof is displaced along the upper wall 12, so that the upward deformation of the terminal 20 is restricted by the upper wall 12.

As described above, according to the connector of the present embodiment, the terminal 20 fixed to the connector main body 10 at one end is formed in a substantially S shape, so that the distance C 2 from the contact portion 26 is short. Because the second bent portion 24 is deformed with the base point as the base point, the direction (X direction) perpendicular to the contact direction (X direction) of the connection object without increasing the size of the connector body 10 and the terminals 20. The displacement amount の of the contact portion 26 can be reduced, which is extremely advantageous for connection with a connection object having a small contact portion with a connector such as a small battery. In this case, since the one end of the terminal 20 is formed to be short in the 、 direction so as to avoid the movable range of the distal end portion 28 displaced in the X direction, the contact portion 26 in the X direction is formed.変位 can be increased. As a result, the contact pressure with the object to be connected can be increased, and poor contact can be reliably prevented. In addition, a space 16 is provided in the connector body 10 for receiving the tip 28 of the terminal 20 displaced in the X direction, so that the tip 28 of the terminal 20 also interferes with the connector 10. Displacement can be performed without any displacement, and the displacement A in the X direction of the terminal 2 ° can be sufficiently ensured.

Furthermore, since the distal end 28 side of the terminal 20 is arranged so as to be deformed while being close to the upper wall 12 of the connector body 10, the distal end 28 side of the terminal 20 is disposed on the upper wall 12. It can be displaced along. In this way, even when the terminal 20 attempts to deform in the Y direction, such as when the object to be connected contacts obliquely, the upward deformation of the terminal 20 is restricted by the upper wall 12. Therefore, the displacement B of the contact portion 26 in the Y direction can be reliably prevented from increasing.

In the above-described embodiment, the terminal 20 is formed in a substantially S-shape. However, if one end of the terminal is formed to avoid the movable range of the other end, the terminal 20 may be formed in a substantially S-shape. It is not limited to the terminal.
