Description

  The present invention relates to an electrical connector, and more particularly to an electrical connector having a plurality of leaf spring-like terminals.

  In order to achieve electrical connection between electronic devices, various types of electrical connectors are used. For example, Patent Document 1 discloses an electrical connector having a structure in which cantilever contacts made of a copper alloy plate are arranged in parallel so as to face each other. When a connection object is coupled to the electrical connector, the contact portion of the leaf spring-shaped cantilever contact is pressed, and the cantilever contact is elastically deformed. In the electrical connector, electrical connection is realized using pressure generated by such elastic deformation of the cantilever contact.

JP 2006-331912 A

  By the way, in the electrical connector using a leaf spring-shaped terminal as described above, the length of the terminal needs to be equal to or longer than the length of the connection portion of the connection object. This is because if the length of the terminal is less than the length of the connecting portion, the connecting portion cannot be completely inserted into the electrical connector, and the electrical connection may be incomplete.

  In addition, when the terminal is short, the load on the terminal due to the coupling with the connection object is large, and the connection function tends to be lowered due to deformation of the terminal or the like. For this reason, the terminal is desired to be long to some extent also from the viewpoint of suppressing the functional deterioration of the terminal due to repeated attachment and detachment and ensuring the reliability of the electrical connector.

  On the other hand, when the terminal is lengthened, the deflection amount of the terminal (displacement amount of the free end) has to be increased in order to realize good electrical connection with sufficient pressure. This is because the amount of deflection of the leaf spring is generally proportional to the product of the cube of the spring length and the load applied to the leaf spring (equal to the force generated by the leaf spring). That is, when the terminal becomes long, it becomes difficult to keep the amount of deflection of the terminal within a predetermined range and to generate a target pressure on the terminal. When the deflection amount of the terminal is increased, problems such as a short circuit due to contact with other members occur. Moreover, in order to avoid this, the problem that an electrical connector must be enlarged also arises.

  The present invention has been made in view of such a point, and an object thereof is to provide an electrical connector capable of generating a desired pressure on a terminal while keeping a deflection amount (displacement amount) of the terminal within a predetermined range. And

  The electrical connector of the present invention has a plurality of leaf spring-like terminals that realize electrical connection by pressure to the connection object, with the contact part side with the connection object as a free end and the fixed part side as a fixed end. The terminal is operable with a protruding portion located between the free end and the fixed end of the terminal as a fulcrum, and the connection object is arranged on the contact portion side from the protruding portion. It has the part which curved in the direction to be.

  In this configuration, when a load opposite to the above-described bending direction is applied to the contact portion, deflection occurs between the free end and the protruding portion and between the protruding portion and the fixed end. This means that both the portion between the free end and the protruding portion and the portion between the protruding portion and the fixed end function as a leaf spring. That is, in this configuration, it is possible to use the force generated by the deflection of the two parts described above. Therefore, even if the deflection amount (displacement amount) between the free end and the protruding portion is small, it is possible to obtain a large pressure against the connection object, so that the terminal deflection amount (displacement amount) is within a predetermined range. A desired pressure can be generated in the terminal while being housed.

  Also, the electrical connector of the present invention is a plurality of leaf spring-like terminals that realize electrical connection by pressure to the connection object, with the contact part side with the connection object as a free end and the fixed part side as a fixed end. And a cover that covers a part of the terminal, and a holding member provided in contact with the cover between a free end and a fixed end of the terminal, wherein the terminal is more than the holding member. The contact portion side has a portion curved in the direction in which the connection object is arranged, and the cover and the holding member enable the operation of the holding member when a load is applied to the contact portion. You may be characterized by contacting through a protrusion part.

  Further, the electrical connector of the present invention is fixed to the housing and the housing, with the contact portion side of the connection target object as a free end and the fixed portion side to the housing as a fixed end. A plurality of leaf spring-shaped terminals for realizing a general connection; a cover that covers a part of the housing and the plurality of terminals; and a free end and a fixed end of the terminals that are in contact with the cover. The terminal has a portion curved in the direction in which the connection object is arranged on the contact portion side of the holding member, and the cover and the holding member are The contact portion may be in contact with each other through a protruding portion that enables the operation of the holding member by applying a load.

  Even in these configurations, the portion between the free end and the holding member (or the protruding portion) and the portion between the holding member (or the protruding portion) and the fixed end all function as a leaf spring. It is possible to use the force generated by the deflection of the two parts. Therefore, even if the amount of deflection between the free end and the holding member (or the protruding portion) is small, it is possible to obtain a large pressure on the connection object, so that the amount of deflection of the terminal is within a predetermined range, A desired pressure can be generated at the terminal.

  In the electrical connector described above, it is preferable that the holding member is provided in common to the plurality of terminals such that the plurality of terminals are arranged in parallel. In this case, since the plurality of terminals are bundled by the holding member, the force exerted on the connection object by each terminal can be made uniform. For this reason, a favorable electrical connection can be realized.

  Moreover, it is preferable to have a plurality of the protruding portions such that the interval between the protruding portion and the free end is larger at the end than the center in the arrangement direction of the plurality of terminals. In this case, the protrusion mainly related to the operation of the terminal at the end of the electric connector is arranged closer to the rear of the electric connector than the protrusion mainly related to the operation of the terminal at the center of the electric connector. The cover of the electrical connector is easily bent at the center, and accordingly, the terminal at the center is less likely to generate pressure on the connection object than the terminal at the end. For this reason, a favorable electrical connection can be realized by arranging a protruding portion mainly involved in the operation of the terminal at the center to facilitate the pressure on the connection object.

  Moreover, it is preferable that the said protrusion part is a part of said holding member. In this case, since the protruding portion can be formed at the same time when the holding member is manufactured, the number of parts is reduced and the manufacturing process is simplified as compared with a case where a member corresponding to the protruding portion is manufactured separately. be able to. Alternatively, the protrusion may be a part of the cover. Also in this case, since the protrusion can be formed at the time of manufacturing the cover, the number of parts can be reduced and the manufacturing process can be simplified as compared with the case where a member corresponding to the protrusion is separately manufactured. it can. The holding member is preferably made of an insulating material, and the cover is preferably made of a conductive material. In this case, since the holding member is an insulator, it is possible to prevent a short circuit between the terminals and a short circuit between the terminal and the cover.

  The plurality of terminals are preferably integrated with the holding member by insert molding. In this case, since the plurality of terminals and the holding member are integrated by an insert molding technique, the number of assembly steps can be reduced and the productivity of the electrical connector can be increased.

  The electrical connector of the present invention has a terminal configured to be able to operate with the protruding portion as a fulcrum. For this reason, it is possible to generate a desired pressure on the terminal while keeping the deflection amount (displacement amount of the free end) of the terminal within a predetermined range.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing an external appearance of an electrical connector 11 according to an embodiment of the present invention. In the following description, the lower left direction (Y direction) in FIG. 1 is referred to as “front” and the upper right direction in FIG. 1 is referred to as “rear” in accordance with the appearance of the electrical connector 11. Also, the upper direction (Z direction) in FIG. 1 is referred to as “up”, the lower direction in FIG. 1 is referred to as “lower”, and the right direction (X direction) in FIG. 1 is referred to as “right”. The direction shall be called “left”.

  As shown in FIG. 1, the electrical connector 11 according to the present embodiment includes a front housing 21 and a lower housing 23 that are molded of an insulating material such as a synthetic resin material, and a punching process in a conductive material such as a metal thin plate material. An inner cover 25 and an outer cover 27 that are formed by bending or the like are provided. The inner cover 25 and the outer cover 27 may be molded from an insulating material such as a synthetic resin material.

  The lower housing 23 has a structure in which a substantially rectangular parallelepiped left side wall portion 101a and a right side wall portion 101b are arranged on the left and right sides, and an inner cover is provided between the left side wall portion 101a and the right side wall portion 101b. 25 is fitted. The inner cover 25 is a hollow cylindrical body that extends from the front to the rear, and the front surface corresponding to the bottom surface of the cylinder is a substantially rectangular shape having a substantially rectangular shape whose left-right direction is the longitudinal direction, with the lower right and lower left corners dropped. It has a hexagonal shape. The inner cover 25 has an opening 105 that is substantially similar to the shape of the front surface, and a front housing 21 that matches the shape of the opening 105 is provided in the space inside the inner cover 25. An outer cover 27 having an opening 107 is installed on the outer periphery of the lower housing 23 and the inner cover 25.

  A substantially rectangular opening 109 exists on the front surface of the front housing 21, and a plurality of terminals 29 are arranged substantially parallel to each other above and below the opening 109. In this electrical connector 11, when the connection portion of the connection object is fitted into the opening 109, the plurality of terminals 29 in the opening 109 bend due to the load from the connection portion, and the pressure corresponding to the amount of deflection is applied to the connection portion. It affects. With this pressure, the electrical connector 11 and the connection object are electrically connected.

  The internal structure of the electrical connector 11 and details of each component will be described with reference to FIGS. 2 and 3 are perspective views for explaining the internal structure of the electrical connector 11 according to the present embodiment. FIG. 4 is a cross-sectional view for explaining the internal structure of the electrical connector 11 according to the present embodiment. Here, in FIG. 2, the main components are shown in a separated state. 3 shows a state in which the inner cover 25 and the outer cover 27 are removed from the electrical connector 11 for convenience of explanation. In the following, the directions of “front”, “rear”, “upper”, “lower”, “left” and “right” indicate directions corresponding to the appearance of the electrical connector 11 as in FIG. .

  As shown in FIG. 2, the electrical connector 11 includes a front housing 21, a lower housing 23, an inner cover 25, an outer cover 27, a terminal 29, and an upper housing 31 and a holding member 33 that are difficult to visually recognize in appearance. . The upper housing 31 and the holding member 33 are also molded from an insulating material such as a synthetic resin material.

  The front housing 21 includes a horizontally long main body 111 having a substantially rectangular opening 109, and a protruding portion 113 a and a protruding portion 113 b that protrude to the left and right of the main body 111. The opening 109 is provided so as to penetrate the main body 111 in the front-rear direction, and the opening 109 has a groove in accordance with the shape and arrangement of the terminal 29 (including the upper terminal 29a and the lower terminal 29b). Is formed. Then, the portion in front of the terminal 29 is accommodated in the opening 109 of the front housing 21 so as to match the groove.

  The terminal 29 is a plate spring-like member formed by punching a metal thin plate material or the like, and can be bent in the vertical direction which is the plate thickness direction. The rear of the upper terminal 29a is flat, the front is slightly curved downward, the rear tip is bent upward, and the front tip is bent upward. A plurality of upper terminals 29a are bundled apart at a predetermined interval by an upper holding member 33a provided near the center of the terminal. The same applies to the lower terminal 29b. That is, the rear of the lower terminal 29b is flat, the front is slightly curved upward, the rear tip is bent downward, and the front tip is bent downward. Further, a plurality of lower terminals 29b are bundled apart at a predetermined interval by a lower holding member 33b provided near the center of the terminal.

  By bundling the plurality of terminals 29 by the holding member 33, the force exerted on the connection object by each terminal 29 can be equalized. For this reason, a favorable electrical connection can be realized. In addition, since the holding member 33 is an insulator, it is possible to prevent a short circuit between the terminals 29 and to prevent a short circuit between the terminal 29 and the inner cover 25. In the present embodiment, a configuration in which the plurality of terminals 29 are bundled by the holding member 33 is shown, but the relationship between the holding member 33 and the terminals 29 need not be limited to this. For example, a plurality of holding members 33 corresponding to the terminals 29 can be provided.

  The rear of the upper terminal 29 a is fixed by the upper housing 31, and the rear of the lower terminal 29 b is fixed by the lower housing 23. The lower housing 23 has a structure in which a substantially rectangular parallelepiped left-side wall portion 101a and a right-side wall portion 101b that are long in the front-rear direction are connected to each other by a substantially rectangular parallelepiped-shaped center support portion 103 that is long in the left-right direction. The upper housing 31 is a substantially rectangular parallelepiped member that is long to the left and right, and is coupled to the upper rear portion of the lower housing 23 after the upper terminal 29a is fixed. After the lower housing 23 and the upper housing 31 are joined, the front housing 21 is joined to the front lower part of the lower housing, and is formed by the front housing 21, the lower housing 23 and the upper housing 31, as shown in FIG. The terminal 29 is stored in the space.

  The terminal 29 and the surrounding structure will be described in more detail. As shown in FIG. 4, the upper housing 31 fixes the upper terminal 29a at the rear fixing portion 117a. For this reason, only the front of the upper terminal 29a is movable. Similarly, the lower housing 23 fixes the lower terminal 29b at the rear fixing portion 117b, and only the front of the lower terminal 29b is movable. Therefore, when the upper terminal 29a and the lower terminal 29b are viewed as leaf springs, the front corresponds to the free end and the rear corresponds to the fixed end.

  An upper holding member 33a is disposed at a position slightly forward from the center of the upper terminal 29a. The upper terminal 29a is slightly curved downward (that is, the side on which the connection object is disposed) in front of the upper holding member 33a, and the front tip portion of the upper terminal 29a has a contact portion 119a with the connection object. It is bent upwards. Further, the upper terminal 29a is substantially parallel to the upper inner wall surface of the inner cover 25 behind the upper holding member 33a, and is bent upward at the rear tip portion to be connected to a wiring or the like.

  The upper holding member 33a is integrally formed with the upper terminal 29a by insert molding, and protrusions 115a to 115e are provided on the upper surface thereof (see FIG. 3). Here, with insert molding, after an insert part is placed in a mold, a resin is injected into the mold to wrap the insert part and solidify the resin, thereby producing an integrated part or a finished product. The construction method. By integrating the plurality of upper terminals 29a and the upper holding member 33a by insert molding, the number of assembly steps can be reduced and the productivity of the electrical connector 11 can be increased. In addition, the formation method of the upper terminal 29a and the upper holding member 33a is not restricted to insert molding. For example, the above-described structure can be realized by using a method such as press fitting.

  In the upper holding member 33a, the projecting portion 115a is disposed closer to the front from the center, and the projecting portion 115b and the projecting portion 115c are disposed slightly rearward in a symmetrical position. In addition, the protrusions 115d and 115e are arranged on the outer sides of the protrusions 115b and 115c and in positions that are symmetrical with respect to the left and right, further toward the rear. In other words, the projecting part located farther left and right from the center is arranged closer to the rear. There is a gap between the front housing 21 and the upper housing 31, and the upper holding member 33a is exposed in the gap. Since the inner cover 25 is arranged in this state, the upper holding member 33a comes into contact with the inner wall of the inner cover 25 at the protruding portions 115a to 115e.

  As described above, the protrusion mainly related to the operation of the terminal 29 at the end of the electric connector 11 (for example, the protrusion) from the protrusion mainly related to the operation of the terminal 29 at the center of the electric connector 11 (for example, the protrusion 115a). By disposing the 115d and the protruding portion 115e) closer to the rear of the electrical connector, a good electrical connection can be realized. This is because the inner cover 25 of the electrical connector 11 is easily bent at the central portion, and accordingly, the terminal 29 at the central portion is less likely to generate pressure on the connection object than the terminal 29 at the end portion. This is because the pressure on the connection object can be easily generated by arranging the projecting portion mainly involved in the operation of the terminal 29 at the center in the front. In addition, although the structure which provides the protrusion part as large as the width | variety of the upper terminal 29a here in five places so that it may become left-right symmetric is shown, about the magnitude | size of a protrusion part, a number, arrangement | positioning, etc. It is not limited to this.

  The structure of the lower terminal 29b and its periphery is the same as that of the upper terminal 29a. That is, the lower holding member 33b is disposed at a position slightly forward from the center of the lower terminal 29b. The lower terminal 29b is slightly curved upward in front of the lower holding member 33b (that is, the side on which the connection object is disposed), and the front tip portion is bent downward through a contact portion 119b with the connection object. is doing. Further, the lower terminal 29b is substantially parallel to the lower inner wall surface of the inner cover 25 behind the lower holding member 33b, and is bent upward at the rear tip portion to be connected to a wiring or the like.

  The lower holding member 33b is integrally formed with the lower terminal 29b by insert molding, and a protrusion (not shown) is provided on the lower surface. The size, number, arrangement, and the like of the protrusions are the same as those of the upper holding member 33a. In other words, the projecting part located farther left and right from the center is arranged closer to the rear. Further, there is a gap between the front housing 21 and the lower housing 23, and the lower holding member 33b is exposed in the gap. Since the inner cover 25 is disposed in this state, the lower holding member 33b comes into contact with the inner wall of the inner cover 25 at the protruding portion. In addition, from the viewpoint of equalizing the pressure due to the contact between the connection object and the lower terminal 29b, it is desirable to match the size, number, arrangement, and the like of the protrusions with the upper holding member 33a, but it is necessary to limit to this. Absent.

  As described above, the electrical connector 11 described above is a leaf spring having a contact portion (contact portion 119a or contact portion 119b) side with a connection object as a free end and a fixed portion (fixed portion 117a or fixed portion 117b) side as a fixed end. The holding member 33 having a protruding portion (such as the protruding portions 115a to 115e) is provided between the free end and the fixed end, so that the terminal 29 operates with the protruding portion as a fulcrum. It is possible. In this configuration, when a load is applied to the contact portion, deflection occurs between the free end and the protruding portion and between the protruding portion and the fixed end. This means that both the portion between the free end and the protruding portion and the portion between the protruding portion and the fixed end function as a leaf spring. That is, in this configuration, it is possible to use the force generated by the deflection of the two parts described above. Therefore, even if the amount of deflection between the free end and the projecting portion is small, it is possible to obtain a large pressure on the connection object, so that the terminal 29 can have a desired amount of deflection while keeping the amount of deflection of the terminal 29 within a predetermined range. Pressure can be generated.

  Here, although the upper holding member 33a and the lower holding member 33b are shown as having a protrusion, the inner cover 25 may have a protrusion. In the case where the upper holding member 33a and the lower holding member 33b are provided with a protruding portion, and in the case where the inner cover 25 is provided with a protruding portion, the number of parts is reduced as compared with the case where a member corresponding to the protruding portion is manufactured separately. And the manufacturing process can be simplified. Of course, only the member corresponding to the protruding portion may be provided separately. In any case, the effect of the present invention can be obtained as long as the configuration has the leaf spring-like terminal 29 that can operate with the protruding portion positioned between the free end and the fixed end as a fulcrum.

  In addition, according to the above-mentioned structure, since it becomes possible to change the length of the terminal 29 comparatively freely, the effect that the freedom degree regarding the design of the electrical connector 11 increases is also acquired. Thereby, it is possible to easily realize downsizing of the electrical connector 11 and the like.

  Next, the state of the electrical connector 11 when a connection object is connected to the electrical connector 11 will be described with reference to FIGS. 5 and 6. FIG. 5 is a partial cross-sectional view showing an initial state before fitting the connection portion 201 of the connection object into the electrical connector 11 according to the present embodiment. FIG. 6 is a partial cross-sectional view showing a state where the connection portion 201 of the connection object is fitted into the electrical connector 11 according to the present embodiment. 5 and 6, only the terminal 229 corresponding to one of the upper terminal 29a and the lower terminal 29b and the surrounding structure will be described for the sake of simplification. In the following, the downward direction (Y direction) in FIGS. 5 and 6 is referred to as “front”, and the upward direction in FIG. 5 is referred to as “rear”. Further, the left direction (Z direction) in FIGS. 5 and 6 is referred to as “up”, and the right direction in FIG. 5 is referred to as “down”.

  As described above, in the electrical connector 11 shown in FIGS. 5 and 6, the holding member 233 having the protruding portion 215 is disposed at a position slightly forward from the center of the terminal 229. The terminal 229 is slightly curved in front of the holding member 233 toward the side where the connection part 201 of the connection object is arranged, and the front end portion of the terminal 229 is connected via the contact part 219 with the connection object. It is bent in the direction opposite to the side where the portion 201 is disposed. Further, the terminal 229 is substantially parallel to the inner wall surface of the inner cover 225 behind the holding member 233, and is bent in a direction opposite to the side where the connecting portion 201 is arranged at the rear end portion. . The terminal 229 is fixed at the fixing portion 217 by the housing 223.

  When the connection part 201 of the connection object is fitted into the electrical connector 11, the terminal 229 receives a downward load (direction opposite to the side where the connection part 201 is arranged) at the contact part 219. Since the terminal 229 is fixed at the fixing portion 217, it is elastically deformed with the fixing portion 217 side as a fixed end. Here, since the holding member 233 is disposed at a position slightly forward of the terminal 229, the free end side portion 241 between the free end and the holding member 233, and between the holding member 233 and the fixed end are arranged. The fixed end portion 243 is bent by receiving a downward force from the connecting portion 201. More specifically, it is as follows.

  The free end portion 241 is slightly curved so as to face upward (the side on which the connection portion 201 of the connection target object is disposed) in a state where it does not receive the external force shown in FIG. 5, but as shown in FIG. When receiving the force from the connecting portion 201, the contact portion 219 is pushed down and deformed into a curved shape having a large curvature radius. As a result, a downward force is applied to the front portion of the holding member 233 (the portion closer to the free end side portion 241 than the protruding portion 215).

  A protrusion 215 is provided on the lower surface of the holding member 233, and the holding member 233 can rotate about the protrusion 215, so that a downward force is applied to the front of the holding member 233. An upward force is applied behind the holding member 233.

  The fixed end side portion 243 has a flat shape substantially parallel to the inner surface of the inner cover 225 in a state where it does not receive the external force shown in FIG. 5, and the rear of the fixed end side portion 243 is fixed by a fixing portion 217. Therefore, when an upward force is applied to the rear of the holding member 233, that is, in front of the fixed end side portion 243, the fixed end side portion 243 is pulled up in front and deformed into a bow shape as shown in FIG. To do.

  That is, the terminal 229 that has received the force from the connecting portion 201 is deformed into a curved shape having a large curvature radius at the free end side portion 241 and is deformed into a bow shape at the fixed end side portion 243, so that the connecting portion 201 is deformed. Generates a pressing force. As described above, by adopting a structure in which the terminal 229 can operate with the protruding portion 215 as a fulcrum, the free end side portion 241 and the fixed end side portion 243 each function like a leaf spring, so that the terminal 229 is sufficient. It is possible to generate a strong force. As a result, it is possible to generate a desired pressure on the terminal while keeping the deflection amount of the terminal 229 within a predetermined range.

  In addition, this invention is not limited to the said embodiment, A various change can be implemented. For example, the size, arrangement, quantity, and the like of each element in the above embodiment can be changed as appropriate. In addition, the present invention can be implemented with appropriate modifications without departing from the scope of the present invention.

  The electrical connector of the present invention can be used for electrical connection of various electronic devices such as personal computers and mobile phones.
