Description

  The present invention relates to a connector.

  For example, Patent Document 1 discloses a technique related to a female contact (terminal) fixed to an insulating housing and conductively connected by insertion of a male contact (connection target). In this prior art, the female contact is formed integrally with the terminal portion connected to the substrate and the terminal portion, fixed to the housing, and cut in a cross section perpendicular to the insertion direction of the male contact. A U-shaped fixing portion (base portion) and a pair of spring portions extending from the end portions of the wall portions facing each other in the fixing portion and sandwiching the male contact.

  The spring portion is composed of a pair of long contact point spring portions and a pair of short contact point spring portions which have different lengths. Therefore, when inserting the male contact into the female contact, first, the pair of long contact point spring portions are elastically deformed in the direction of separating from each other, and the male contact is inserted between the pair of long contact point spring portions. The short contact point spring portions are elastically deformed in a direction in which they are separated from each other, and a male contact is inserted between the pair of short contact point spring portions.

  The long contact spring portion and the short contact spring portion are set to be in contact with the surface of the male contact. As a result, in a connector provided with such a spring portion, even if either one of the long contact spring portion and the short contact spring portion fails to conduct, as long as the other is in contact with the male contact, The conductively connected state is maintained.

JP-A-3-77285

  However, in the above prior art, the long contact spring portion and the short contact spring portion are respectively formed on the wall portions which are a part of the fixed portion of the female contact. And since this fixing | fixed part is making the cross-sectional shape the U-shape, it is easy to produce elastic deformation via a long contact point spring part and a short contact point spring part.

  That is, due to the elastic deformation of the long contact point spring part and the short contact point spring part, the fixed part bent and formed in a substantially U shape is easily deformed in the direction in which the cross section opens. Therefore, for example, even if the long contact spring is in contact with the male contact with an appropriate contact pressure, when the short contact spring which contacts thereafter is elastically deformed, the fixed part is deformed under the influence of that. there's a possibility that.

  Temporarily, if the fixed part is deformed, the long contact point spring part is displaced in the direction of separating from the male contact with the deformation of the fixed part, and the contact pressure at which the long contact point spring part contacts the surface of the male contact is reduced. Contact pressure may not be obtained.

  In view of the above facts, the present invention maintains contact pressure on a connection object at each contact even if the connection object has a plurality of different contacts along the insertion direction of the connection object. Aims to obtain a connector that can

  A connector according to the present invention according to claim 1 is fixed in a housing and a housing portion formed in the housing, and a connection target made of a conductive material is inserted through an opening formed in the housing. Or a terminal made of an electrically conductive material which is removed and the terminal is a base on which a fixing part to be fixed to the housing part is formed, and the opening side of the base is a front part A first contactor extending from the front side with respect to the fixed portion at the base and elastically contacting the connection object, and a rear side of the fixed portion at the base; And a second contactor resiliently contacting the connection object.

  In the connector according to the first aspect of the present invention, the terminal made of the conductive material is fixed in the housing portion formed in the housing. A connection target made of a conductive material is inserted into or withdrawn from the terminal through an opening formed in the housing.

  On the other hand, the terminal includes the base, the first contact, and the second contact. The base is formed with a fixed portion fixed to the housing, and in the base, the opening side of the housing is the front, and the first contactor extends from the front side with respect to the fixed portion. And this 1st contact child contacts elastically with respect to a connection subject. Moreover, in the base, the second contactor is extended from the rear side of the fixed portion, and the second contactor elastically contacts the connection object.

  That is, in the present invention, the first contactor and the second contactor are formed on the base that constitutes a part of the terminal, and the first contactor and the second contactor are resilient with respect to the connection object They are in contact and have different contact points along the insertion direction of the connection object.

  Further, the first contactor is extended from the front side with respect to the fixing portion of the base, and the second contactor is set to extend from the rear side with respect to the fixing portion of the base. Here, since the fixing portion of the base is fixed to the housing, the first contact and the second contact are extended independently of each other with respect to the base. Thereby, the first contact and the second contact are divided through the fixing portion, and even if the first contact is elastically deformed, the deformation of the first contact does not reach the second contact. can do.

  That is, the transmission of stress that deforms the first contactor and the second contactor is blocked by the fixing portion, and the first contactor and the second contactor elastically deform in an independent state. Therefore, it is suppressed that the 2nd contact is elastically deformed under the influence of the elastic deformation of the 1st contact, and it is suppressed that the 1st contact is elastically deformed under the influence of the elastic deformation of the 2nd contact. can do. As a result, the first contactor and the second contactor can maintain the desired contact pressure with respect to the connection object while in contact with the connection object, and are stable between the connector and the connection object Can be connected.

  The connector according to the second aspect of the present invention is the connector according to the first aspect of the present invention, wherein the first free end portion formed on the free end side of the first contact and the second contact The second free end portion formed on the free end side is disposed back and forth along the insertion direction of the connection object, and can be brought into contact with the surface of the connection object.

  In the connector according to the second aspect of the present invention, the first free end formed on the free end side of the first contact and the second free end formed on the free end of the second contact are: It arrange | positions back and forth along the insertion direction of a connection object. Therefore, for example, when the first free end of the first contact is disposed closer to the opening of the housing than the second free end of the second contact, the connection target is inserted into the opening of the housing Then, the connection object first contacts the first free end of the first contact. Then, next, the connection object contacts the second free end of the second contact.

  In the present invention, since the first free end of the first contact and the second free end of the second contact elastically contact the connection object, the connection object is provided in the housing. When is inserted, the surface of the connection object is slid by at least the first free end of the first contact and the second free end of the second contact.

  In this case, even if foreign matter is attached to the surface of the connection object, the foreign matter attached to the surface of the connection object is removed by sliding on the first free end of the first contact. Then, with the foreign matter removed on the surface of the connection object, the second free end of the second contact comes into contact with the surface of the connection object.

  Also, even if the first free end of the first contact runs on the foreign object adhering to the surface of the connection object, the second free end of the second contact is the connection object without foreign object. It adheres to the surface. Therefore, in the present invention, the conduction connection can be reliably made between the terminal and the connection object, whereby the conduction failure can be prevented between the terminal and the connection object.

  The connector according to the present invention described in claim 3 is the connector according to the present invention described in claim 2, wherein the first contactor is a front contactor extended from the front side of the fixed portion, The first free end portion is a front contact portion formed on the free end side of the front contact, and the second contact is a rear contact extending from the rear side of the fixed portion, and The second free end portion is a rear contact portion which is formed on the free end side of the rear contact and is disposed on the base side with respect to the front contact portion.

  In the connector according to the third aspect of the present invention, the first contactor is a front contactor extended from the front side with respect to the fixing portion, and the second contactor extends from the rear side with respect to the fixing portion It is a rear contact that has been taken out. A front contact portion is formed on the free end side of the front contact, and the front contact portion contacts the surface of the connection object. In addition, a rear contact portion is formed on the free end side of the rear contact, and the rear contact portion is disposed closer to the base than the front contact portion and contacts the surface of the connection object.

  As described above, the front contact extends from the front side of the fixed portion of the base, and the rear contact extends from the rear side of the fixed portion of the base. For example, when the front contact portion formed on the free end side of the front contact and the rear contact portion formed on the free end of the rear contact are disposed at the same position along the insertion direction of the connection object Assume. In this case, the extension length (length from the root to the tip (rear contact portion)) of the rear contact is longer than the extension length of the front contact, and the plate thickness of the front contact and the rear contact is If they are substantially the same, the rear contact will have a lower spring constant than the front contact.

  Therefore, in the present invention, the rear contact portion of the rear contact extended from the rear side of the base with respect to the front contact is disposed on the base side of the front contact of the front contact. Thereby, it is possible to suppress the deviation of the extension length of the front contact and the rear contact caused by the difference in the extension position with respect to the base.

  That is, by making the extension length of the front contact and the extension length of the rear contact substantially the same, when the plate thickness of the front contact and the rear contact is the same, a spring is generated by the front contact and the rear contact. The constants can be approximately the same. As a result, the front contact and the rear contact can have substantially the same elastic force, and the front contact portion and the rear contact can have substantially the same pressing force (elastically contact) on the connection object. it can.

  The connector according to the fourth aspect of the present invention is the connector according to the third aspect, wherein the front contact portion is orthogonal to the insertion direction in which the connection object is inserted into the opening. The rear contact extends from one end of the base in the width direction, and the rear contact extends from the other end of the base in the width direction.

  In the connector according to the fourth aspect of the present invention, the front contact portion is, in the base portion, in an insertion direction in which the connection object is inserted into the opening of the housing It extends from one end in the width direction of the base orthogonal to the other. On the other hand, the rear contact is extended from the other end in the width direction of the base.

  Therefore, when the terminal is viewed from the front side, it is possible to form a closed cross section by the base, the front contact and the rear contact. Thereby, in a terminal, compared with the case where the said closed section is not constituted, rigidity of terminal itself can be improved and modification of terminal itself can be controlled.

  The connector according to the fifth aspect of the present invention is the connector according to the fourth aspect, wherein the connector is formed on the root side of the rear contact and extends perpendicularly to the base from the other end in the width direction of the base The width of the base formed on the root side of the front contactor and the rear support portion disposed at the rear contact portion orthogonal to the rear connection portion and opposed to the base in the rear contact portion taken out A front connecting portion extending perpendicularly to the base from one end of the direction and overlapping with a front end of the rear connecting portion in a side view, and the front contactor, which is orthogonal to the front connecting portion and the rear And a front support portion disposed opposite to the support portion.

  In the connector according to the fifth aspect of the present invention, the rear connecting portion is formed on the root side of the rear contact. The rear connection portion is extended perpendicularly to the base from the other end in the width direction of the base. Further, the rear contact portion is formed with a rear support portion which is disposed to be orthogonal to the rear connection portion and to face the base.

  On the other hand, a front connecting portion is formed on the root side of the front contact, and the front connecting portion is formed to overlap the front end of the rear connecting portion in a side view. Further, the front contact portion is formed with a front support portion which is disposed to be orthogonal to the front connection portion and to face the rear support portion.

  That is, in the present invention, the terminal is formed such that the front connection portion and the front end portion of the rear connection portion overlap in a side view, and the base, the rear support portion, and the front support portion overlap in a plan view. Thus, in the cross-sectional shape of the terminal cut along the direction substantially orthogonal to the insertion direction of the connection object, the base, the front contact and the rear contact can constitute a closed cross-sectional portion. Thereby, the rigidity of the terminal itself can be improved, and the deformation of the terminal itself can be suppressed.

  Here, “orthogonal” in “perpendicular to the base” is a meaning including not only the case of being completely orthogonal but also the case where the angle is deviated with respect to the perfect orthogonal including the dispersion at the time of manufacture That is, so-called "substantially orthogonal".

  A connector according to the present invention as set forth in claim 6 is the connector according to any one of claims 3 to 5, which extends from the front end of the base toward the opening, and the front contact An extension part for holding the connection object is provided together with the part and the rear contact part.

  In the connector according to the sixth aspect of the present invention, the extension portion extends from the front end of the base toward the opening. Since the front contact portion of the front contact and the rear contact portion of the rear contact elastically contact the connection object, the connection object is inserted between the extension and the front contact portion and the rear contact portion The connection object is elastically held by these.

  A connector according to the present invention as set forth in claim 7 is the connector according to claim 6, wherein a first opposing portion where the front contact portion in the extension portion is opposed to a second opposing portion where the rear contact portion is opposed. A flat portion is formed throughout.

  In the connector according to the seventh aspect of the present invention, in the extension portion, the flat portion is formed from the first facing portion facing the front contact portion to the second facing portion facing the rear contact portion. The flat portion contacts the surface of the connection object in a state in which the connection object is held between the extension portion and the front contact portion and the rear contact portion.

  As a result, the contact area between the connection target and the terminal is increased, and movement of the connection target such as rotational movement can be suppressed in a state where the connection target is held between the terminals. As described above, in the state where the connection object is pressed by the front contact portion and the rear contact portion, it is possible to prevent the sliding with respect to the front contact portion and the rear contact portion by suppressing the movement of the connection object. Thereby, it is possible to suppress that the plating applied to the surface of the front contact portion or the rear contact portion is peeled off and the conduction state is deteriorated.

  As described above, even if the connector according to the present invention has a plurality of contact points different from the connection object along the insertion direction of the connection object, the contact pressure on the connection object at each contact point Have the excellent effect of being able to maintain

That is, the front contact 28 and the rear contact 30 are separated through the fixing portion 18, and even if the front contact 28 is elastically deformed, the deformation of the front contact 28 does not reach the rear contact 30. You can do so.

  In other words, in the present embodiment, the transmission of stress that deforms the front contact 28 and the rear contact 30 is blocked by the fixing portion 18, and the front contact 28 and the rear contact 30 elastically deform in an independent state. Therefore, it suppresses that the rear contact 30 elastically deforms following the elastic deformation of the front contact 28, and suppresses the elastic deformation of the front contact 28 following the elastic deformation of the rear contact 30. can do.

  As a result, as shown in FIG. 9B, the front contact 28 and the rear contact 30 of the terminal 14 maintain the desired contact pressure against the connection pin 15 in contact with the connection pin 15, respectively. And a stable, conductive connection can be made between the terminal 14 and the connection pin 15.

  That is, even if the connector 10 in the present embodiment has a plurality of contact points (the front contact portion 48 and the rear contact portion 38) different from the connection pin 15 along the insertion direction of the connection pin 15, each contact is , The contact pressure on the connection pin 15 can be maintained.

  Further, in the present embodiment, as shown in FIG. 9A, the front contact portion 48 and the rear contact portion 38 are disposed back and forth along the insertion direction of the connection pin 15 (arrow A direction). . Therefore, for example, when the connection pin 15 is inserted into the insertion portion 50 of the terminal 14, the connection pin 15 first contacts the front contact portion 48 provided on the free end side of the front contact 28. Then, next, the connection pin 15 contacts the rear contact portion 38 provided on the free end side of the rear contact 30.

  Here, as shown in FIG. 9B, the connection pin 15 is elastically held by the extension piece 24 and the front contact portion 48 of the front contact 28 and the rear contact portion 38 of the rear contact 30. It is supposed to be. Therefore, when the connection pin 15 is inserted between the extension piece 24 and the front contact 28 and the rear contact 30, the surface 15B of the connection pin 15 slides by at least the front contact portion 48 and the rear contact portion 38. It will be done.

  Thereby, although not shown, even if foreign matter is attached to the surface 15B of the connection pin 15, the foreign matter attached to the surface 15B of the connection pin 15 is removed by sliding on the front contact portion 48. Then, with the foreign matter removed on the surface 15B of the connection pin 15, the rear contact portion 38 comes in contact with the surface 15B of the connection pin 15. Therefore, in the present embodiment, conductive connection can be reliably made between the connector 10 and the connection pin 15.

  Also, even if the front contact portion 48 of the terminal 14 rides on the foreign matter attached to the surface 15B of the connection pin 15, the rear contact portion 38 contacts the surface 15B of the connection pin 15 without foreign matter. That is, in the present embodiment, the conduction connection can be reliably performed between the terminal 14 (connector 10) and the connection pin 15. In other words, in the present embodiment, a conduction failure can be prevented between the terminal 14 (connector 10) and the connection pin 15.

  On the other hand, as shown in FIGS. 6 and 7, in the present embodiment, as described above, the front contact 28 extends from the front portion 16B of the base 16, and the rear contact 30 intervenes the fixing portion 18 therebetween. And set to extend from the rear portion 16D of the base 16. The front contact portion 48 of the front contact 28 and the rear contact portion 38 of the rear contact 30 are located on the front side with respect to the base portion 16 respectively.

  For example, although not shown, it is assumed that the front contact portion 48 and the rear contact 30 are disposed at the same position in the insertion direction of the connection pin 15. In this case, the extension length (the length from the root to the tip) of the rear contact 30 is longer than the extension length of the front contact 28. Since the terminal 14 in the present embodiment is formed of one metal plate member, the plate thickness of the front contact piece 46 and the rear contact piece 36 is substantially uniform. For this reason, the rear contact 30 has a lower spring constant than the front contact 28.

  Therefore, in the present embodiment, the rear contact portion 38 of the rear contact 30 extending from the rear portion 16D of the base 16 relative to the front contact 28 is disposed closer to the base 16 than the front contact portion 48 of the front contact 28. ing. Thereby, it is possible to suppress the deviation of the extension length of the front contact 28 and the rear contact 30 caused by the difference in the extension position with respect to the base 16.

  And, by making the extension length of the front contact 28 and the extension length of the rear contact 30 approximately the same, when the plate thickness of the front contact 28 and the rear contact 30 is the same, the front contact 28 and the rear contact 30 are the same. The spring constants can be made substantially the same as the contacts 30. As a result, the front contact 28 and the rear contact 30 have substantially the same elastic force, and the front contact portion 48 and the rear contact portion 38 have substantially the same pressing force for pressing (elastically contacting) the connection pin 15. Can be

  In the present embodiment, as described above, in the rear contact 30, the rear connection piece 32 is suspended relative to the base 16, and from the lower end of the rear connection piece 32, the rear connection piece 32 is substantially orthogonal to the rear connection piece 32 and the base A rear support piece 34 opposed to the extension piece 24 and the extension piece 24 is extended. On the other hand, in the front contact 28, the front connection piece 42 is suspended from the base 16, and from the lower end of the front connection piece 42, it is substantially orthogonal to the front connection piece 42 and faces the rear support piece 34 and the extension piece 24. A front support piece 44 is extended. Then, as shown in FIG. 10A, the rear portion 42C of the front connection piece 42 and the front portion 32A of the rear connection piece 32 are set to overlap as viewed from the side.

  That is, in the present embodiment, as shown in FIG. 10A, the terminal 14 overlaps the rear portion 42C of the front connection piece 42 and the front portion 32A of the rear connection piece 32 in a side view, and FIGS. As shown in FIG. 1, the base 16, the rear support piece 34 and the front support piece 44 are formed to overlap when viewed from the upper side.

  Thus, in the cross-sectional shape of the terminal 14 cut along a direction substantially orthogonal to the insertion direction of the connection pin 15 (the direction of the arrow A shown in FIG. 9A), the base 16, the front contact 28 and the rear The contact 30 and the closed cross section 52 (see FIG. 8) can be configured. Thereby, the rigidity of the terminal 14 itself can be improved, and the deformation of the terminal 14 itself can be suppressed.

  Further, in the present embodiment, as shown in FIG. 9A, in the extension piece 24, the facing portion (first facing portion) P facing the front contact portion 48 is a facing portion facing the rear contact portion 38 (the first facing portion). A flat portion 26 is formed across the second opposing portion Q). Therefore, as shown in FIG. 9B, the flat portion 26 is formed on the surface 15B of the connection pin 15 in a state where the connection pin 15 is held between the extension piece 24 and the front contact portion 48 and the rear contact portion 38. Will be in contact.

  As a result, the contact area between the connection pin 15 and the terminal 14 (specifically, the extension piece 24 and the front contact portion 48 and the rear contact portion 38) is increased, and connection is performed in a state where the connection pin 15 is held by the terminal 14 Movement such as rotational movement of the pin 15 can be suppressed.

  As described above, in the state where the connection pin 15 is pressed by the front contact portion 48 and the rear contact portion 38, the movement of the connection pin 15 is suppressed to prevent the sliding with respect to the front contact portion 48 and the rear contact portion 38. Can. Thereby, it is possible to suppress that the plating applied to the surfaces of the front contact portion 48 and the rear contact portion 38 peels off and the conduction state is deteriorated.

  Furthermore, in the present embodiment, as shown in FIG. 10A, the front contact piece 46 extends from the front end of the front support piece 44, with the front contact portion 48 as the top, and the rear contact piece 36 as the rear It extends from the front end of the support piece 34 and is formed with the rear contact portion 38 as a top.

  The front contact piece 46 and the rear contact piece 36 are set to have substantially the same length. As described above, since the terminal 14 in the present embodiment is formed of one metal plate member, the plate thickness of the front contact piece 46 and the rear contact piece 36 is substantially uniform. Therefore, the spring constants of the front contact piece 46 and the rear contact piece 36 are substantially the same, and the biasing force can be made substantially the same in a state where the connection pin 15 is in contact with the front contact piece 46 and the rear contact piece 36 . That is, the front contact portion 48 and the rear contact portion 38 can hold the connection pin 15 with substantially the same holding force with the extension piece 24.

(Supplement of this embodiment)
In the present embodiment, the first contactor extending from the front side with respect to the fixing portion is the front contactor 28, and the second contactor extending from the front side with respect to the fixing portion is the rear contact 30. The first contact may be the rear contact 30 and the second contact may be the front contact 28.

  Moreover, in this embodiment, although the metal plate of 1 sheet is bent and the terminal 14 is formed, a terminal may be formed including a some metal plate or another member. Thereby, the rigidity of the terminal 14 may be effectively improved by partially thickening the plate thickness of the terminal 14 or the like. Further, the method of forming the terminal 14 is not limited to bending, and it is needless to say that the terminal 14 may be formed by other forming methods such as electroforming, injection molding, die casting, cutting and the like.

  Furthermore, in the present embodiment, the front contact portion 48 and the rear contact portion 38 are disposed back and forth, that is, on the same straight line along the insertion direction (direction of arrow A) of the connection pin 15. It does not have to be placed in

  Furthermore, in the present embodiment, as shown in FIG. 10A, the terminal 14 overlaps the rear portion 42C of the front connection piece 42 and the front portion 32A of the rear connection piece 32 in a side view, and FIGS. As shown in FIG. 7, the base 16, the rear support piece 34 and the front support piece 44 are formed to overlap with each other when viewed from the upper side. And although the rigidity of terminal 14 itself is improved by this in this embodiment, since it is sufficient if the rigidity of terminal 14 can be improved, it does not restrict to this. For example, the plate thickness of the rear support piece 34 and the front support piece 44 may be increased.

  Further, in the present embodiment, as shown in FIGS. 6 and 7, the front contact 28 of the terminal 14 extends from the left end portion 16C of the base 16 on the front side of the fixed portion 18 of the base 16 The rear contact 30 extends from the right end portion 16E of the base 16 on the rear side of the fixed portion 18 of 16.

  That is, in the present embodiment, the front contact 28 extends from one end (left end 16C) in the width direction at the front portion 16B of the base 16 and the terminal 14 extends in the width direction of the base 16 at the rear portion 16D of the base 16. Although the rear contact 30 extends from the other end (right end 16E), the present invention is not limited to this. For example, the front contact 28 and the rear contact 30 may extend from one end in the width direction of the base 16.

  Specifically, for example, as shown in FIGS. 11 to 13, in the front portion 56A of the base portion 56 of the terminal 54, the front contact (first contact) 58 from the right end portion (one end in the width direction) 56B. The rear contact (second contact) 60 may extend from the right end 56B at the rear portion 56C of the base 56 in the same manner as the front contact 58.

  Further, in the present embodiment, as shown in FIG. 5, when the connection pin 15 is inserted, the connection pin 15 is held between the extension piece 24 and the front contact portion 48 and the rear contact portion 38. However, the extension piece 24 is not always necessary. However, in this case, the ceiling portion 12A of the housing 12 is formed to be connected to the communication port 20A of the opening 20. Thus, the connection pin 15 is held between the ceiling 12A of the housing 12 and the front contact 48 and the rear contact 38.

  Furthermore, in the present embodiment, as shown in FIG. 9A, in the extension piece 24, a flat portion extends from the facing portion P where the front contact portion 48 faces to the facing portion Q where the rear contact portion 38 faces. 26 are formed. Thus, movement of the connection pin 15 such as rotational movement can be suppressed in a state in which the connection pin 15 is held between the terminals 14. However, the flat portion 26 is necessarily formed from the facing portion P to the facing portion Q. It does not have to be done. The flat portion 26 is formed to be substantially horizontal at a position one step lower than the surface of the base 16 when viewed from the side, but may be formed flush with the base 16.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited above, Of course, it can be variously deformed and implemented in the range which does not deviate from the main point other than the above. It is
