JP 58-212081 A

  However, the female terminal has to be configured such that the pressing portion provided with the lock claw presses the male terminal toward the flange, so that the distal end of the pressing portion must be pushed away from the flange portion. In this case, the lock claw cannot be removed from the lock hole. That is, since the male side terminal must be pulled out from between the pressing portion and the flange portion while keeping the state where the tip of the pressing portion is pressed down and the lock claw is detached from the lock hole, The female terminal has a drawback that it is difficult to remove the male terminal.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a female-side terminal and an inter-terminal connection structure in which a male-side terminal can be easily removed.

  In order to solve the above problems, the female terminal of the present invention is a female terminal that can be connected to a male terminal having a lock claw provided in the head portion, and is provided with a lock hole into which the lock claw can be inserted. The base is provided with a substantially U-shaped folded portion that is substantially transverse in cross-section when the first end is continuous to the base, and a pressing portion that is continuous with the second end of the folded portion. The folded portion is elastically deformed, and the second end portion can be displaced in a direction away from the first end portion, and the pressing portion is bent toward the base portion and between the base portion. The head part has a gap into which the head part can be inserted, and the distance between the pressing part and the base part is smaller than the thickness dimension of the head part.

  In the case of such a female-side terminal, since the distance between the pressing portion and the base portion is smaller than the thickness dimension of the head portion, the head portion is inserted between the pressing portion and the base portion. The folded portion is elastically deformed and the second end portion is displaced in a direction away from the first end portion. Accordingly, the pressing portion presses the head portion toward the base portion. For this reason, the lock claw of the head portion is locked in a state of being inserted into the lock hole of the base portion. Since the head portion is pressed toward the base portion by the pressing portion in this way, when removing the head portion, the male-side terminal is used with a tip portion that contacts the base portion of the head portion as a fulcrum. By simply lifting up in a direction away from the base, the lock claw of the head part comes out of the lock hole of the base. In this state, the male terminal can be easily removed simply by pulling out the head portion from between the pressing portion and the base portion.

  It is preferable that the pressing portion is bent in a substantially V shape in cross section. In this case, the distal end portion of the pressing portion is inclined in a direction away from the base portion, and the distal end portion of the pressing portion guides the head portion of the male terminal into the gap between the pressing portion and the base portion. Since it functions as a guide part, it becomes easy to insert the head part of the male terminal into the gap.

  It is preferable that the width dimension of the lock hole is larger than the width dimension of the lock claw. In this case, the lock claw can be moved in the width direction in a state where the lock claw is inserted into the lock hole. For this reason, it becomes possible to permit the position shift to the said width direction of the said male side terminal.

  It is preferable that the length dimension of the lock hole is larger than the length dimension of the lock claw. In this case, in this case, the lock claw can be moved in the length direction with the lock claw being inserted into the lock hole. For this reason, it becomes possible to permit the position shift to the said length direction of the said male side terminal.

  The female terminal has a pair of side walls standing at both ends in the width direction of the base, and a pair facing the inner side of the upper end of the side wall with a gap in the pressing part. The flange portion can be further provided. In this case, the flange portion is opposed to the pressing portion with a gap. For this reason, when the male side terminal is lifted in the direction away from the base portion with the tip portion of the head portion coming into contact with the base portion as a fulcrum, the flange portion comes into contact with the pressing portion lifted up by the head portion, It is possible to prevent the pressing portion from being lifted more than a predetermined amount. Therefore, it is possible to prevent the pressing portion from being lifted by a predetermined amount or more and the folded portion to be plastically deformed.

  The inter-terminal connection structure of the present invention includes the female side terminal and a male side terminal connected to the female side terminal. The male terminal has a head portion provided with a lock claw. The head portion is pressed by the pressing portion toward the base portion, and a lock claw of the head portion is inserted into the lock hole of the base portion.

  When a lock hole is provided in the head portion of the male terminal instead of a lock claw, a lock claw that can be inserted into the lock hole of the male terminal is provided in the base portion instead of the lock hole. Even in this case, the same effect as described above can be obtained.

  Another inter-terminal connection structure of the present invention includes a female side terminal provided with a lock claw at the base, and a male side terminal connected to the female side terminal. The head portion is pressed by the pressing portion toward the base portion, and the lock claw of the base portion is inserted into the lock hole of the head portion.

  The male terminal may further include a bent portion that is continuous with the head portion. The bent portion is bent so that the lower surface of the head portion and the upper surface of the base portion of the female terminal have substantially the same height. In this case, in a state where the head portion of the male terminal is inserted between the base portion of the female terminal and the pressing portion, the height position of the main body portion of the male terminal and the base portion of the female terminal. Can be prevented from differing.

  The female terminal may further include a mounting portion mounted on the first substrate, and the male terminal may further include a mounting portion mounted on the second substrate.

  Hereinafter, an inter-terminal connection structure according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. The inter-terminal connection structure shown in FIGS. 1 and 2 includes a pair of female terminals 100 mounted on the first substrate 10 and a pair of male terminals 200 mounted on the second substrate 20. . Thus, this inter-terminal connection structure realizes multipolar connection of the first and second substrates 10 and 20 by using the pair of female terminals 100 and male terminals 200. Hereinafter, the female terminal 100 and the male terminal 200 will be described in detail.

  As shown in FIGS. 1, 2, and 4, each male terminal 200 is formed by press-molding a conductive metal plate. The male terminal 200 has a head part 210, a bent part 220, a main body part 230, and six mounting parts 240.

  The head part 210 is a substantially rectangular plate. The front end portion of the head portion 210 has a tapered shape in which the thickness dimension and the width dimension are gradually reduced. A lock claw 211 is provided at the base end portion of the head portion 210. The lock claw 211 is a rounded piece obtained by cutting and bending the central portion of the base end portion of the head portion 210.

  The main body 230 is a rectangular plate. Three mounting portions 240 are disposed at both ends in the width direction of the main body portion 230 at intervals. The mounting portion 240 is a substantially rectangular plate body, and its base end portion is bent downward. Therefore, as shown in FIG. 4A, the height position of the lower surface of the front end portion of the mounting portion 240 is located below the height position of the lower surface of the main body portion 230. The tip of the mounting part 240 is a part that is soldered to the wiring line 21 of the second substrate 20.

  The bent portion 230 is a plate body that connects the main body portion 230 and the head portion 210. As shown in FIG. 5, the bent portion 230 is a body in which the first and second substrates 10 and 20 are installed on the same surface, and the height position of the lower surface of the head portion 210 is the height of the female terminal 100. It is bent so that the height position of the upper surface of the base 110 is substantially the same.

  As shown in FIGS. 1 to 3, each female terminal 100 is formed by press-molding a conductive metal plate. The female terminal 100 includes a base portion 110, a pair of side wall portions 120, a pair of flange portions 130, a folded portion 140, a pressing portion 150, and a pair of mounting portions 160.

  As shown in FIG. 3D, the base 110 is a plate-like body that has a wide portion 111 and a narrow portion 112 and has a substantially convex shape when viewed from the bottom. Both ends in the width direction of the wide portion 111 are bent upward as shown in FIG. For this reason, the height position of the center part between the said both ends of the wide part 111 is high compared with the height position of the said both ends. In addition, a substantially rectangular lock hole 113 into which the lock claw 211 of the male terminal 200 can be inserted is formed at the center of the wide portion 111 and the narrow portion 112. As shown in FIGS. 3 to 5, the length L1 of the lock hole 113 is longer than the length L2 of the lock claw 211 of the male terminal 200, and the width dimension W1 of the lock hole 113 is the lock of the male terminal 200. The claw 211 is wider than the width dimension W2. Therefore, the lock claw 211 of the male terminal 200 is movable in the length direction and the width direction while being inserted into the lock hole 113. The lock claw 211 and the lock hole 113 function as a float mechanism corresponding to a positional shift in the XY direction described later of the first and second substrates 10 and 20.

  As shown in FIGS. 3B, 3C, and 3D, a pair of mounting portions 160 are provided at both ends in the width direction of the narrow portion 112, respectively. The mounting portion 160 is a substantially rectangular plate body, and its base end portion is bent downward. For this reason, the height position of the lower surface of the front end portion of the mounting portion 160 substantially matches the height position of the lower surface of both end portions of the wide portion 111. The tip of the mounting part 160 is a part to be soldered to the wiring line 11 of the substrate 10.

  Moreover, as shown in FIG.3 (c) and FIG.3 (e), the lower end part 141 of the folding | turning part 140 is provided in the rear end of the narrow part 112 continuously. The folded portion 140 is a plate body folded in a substantially U shape in a cross-sectional view. The folded portion 140 is elastically deformed so that the upper end portion 142 (second end portion) can be displaced in a direction away from the lower end portion 141 (first end portion) (that is, upward). As shown in FIG. 5, a pressing portion 150 is continuously provided on the upper end portion 142 of the folded portion 140. The pressing portion 150 includes an arm 151 and a pressing portion main body 152. The arm 151 is an elastically deformable plate that is continuous with the upper end 142 of the folded portion 140 and is bent substantially at a right angle toward the base 110. The pressing portion main body 152 is a substantially V-shaped plate body that can be elastically deformed and is continuous with the lower end of the arm 151. The pressing portion main body 152 is disposed opposite to the base portion 110 with a gap α. This gap α becomes an insertion space into which the head portion 210 of the male terminal 200 is inserted.

  The height dimension of the gap α (that is, the distance between the top portion of the pressing portion main body 152 and the base portion 110) is smaller than the thickness dimension T of the base end portion of the head portion 210 of the male terminal 200. For this reason, when the head portion 210 of the male terminal 200 is inserted into the gap α, the folded portion 140 is elastically deformed, the upper end portion 142 is displaced upward, and the pressing portion 150 is elastically deformed. Due to the elastic force of the folded portion 140 and the pressing portion 150, the pressing portion main body 152 presses the head portion 210 of the male terminal 200 toward the base portion 110. For this reason, the state where the lock claw 211 of the head part 210 of the male terminal 200 is inserted into the lock hole 113 of the base part 110 is maintained. Moreover, the front-end | tip part of the press part main body 152 inclines toward diagonally upward. In other words, since the distal end portion of the pressing portion main body 152 is inclined downward toward the gap α, when the head portion 210 of the male terminal 200 is moved forward while the distal end portion is in contact with the distal end portion, the head portion 210 is moved to the clearance α. Be guided to. That is, the distal end portion of the pressing portion main body 152 functions as a guide for guiding the head portion 210 to the gap α.

  Further, as shown in FIGS. 1, 2, 3 (a), 3 (b), and 3 (e), a pair of side wall portions 120 are respectively provided at both ends of the wide portion 111 of the base 110. It is erected. The side wall 120 is a rectangular plate that is bent at a substantially right angle to the base 110. The distance between the side wall parts 120 is larger than the width dimension of the head part 210 of the male side terminal 200, as shown in FIG. That is, the distance between the side wall portion 120 and the head portion 210 defines an allowable range of positional deviation of the head portion 210 in the Y and −Y directions.

  As shown in FIG. 3A, FIG. 3C, and FIG. 5, a pair of flange portions 130 that are substantially L-shaped in plan view are provided on the upper end portion of the side wall portion 120, respectively. A projecting stopper 131 is provided at the rear end of the flange 130. The stopper 131 is disposed above the pressing portion main body 152 with a space therebetween. In other words, the stopper 131 can come into contact with the pressing portion main body 152. The abutting portion 131 abuts against the pressing portion main body 152 to prevent the pressing portion main body 152 from being displaced upward by a predetermined amount or more, and the folded portion 140 is plastically deformed by the displacement of the pressing portion main body 152 by a predetermined amount or more. Is prevented.

  Hereinafter, the operation of each unit will be described together with the procedure for connecting the male terminal 200 to the female terminal 100 described above. First, as shown in FIG. 5B, the head portion 210 of the male terminal 200 is pushed into the gap α of the female terminal 100. Even if the head portion 210 cannot be inserted into the gap α and is in contact with the distal end portion of the pressing portion main body 152 of the female terminal 100, the head portion 210 is brought into contact with the distal end portion of the pressing portion main body 152. When the head portion 210 is advanced while being in contact, the head portion 210 is guided to the gap α by the tip portion.

  When the head portion 210 is pushed into the gap α, the pressing portion main body 152 is displaced upward, and the pressing portion 150 and the folded portion 140 are elastically deformed as described above. Thereby, the pressing portion main body 152 presses the head portion 210 toward the base portion 110. At this time, the lock claw 211 of the head part 210 is inserted into the lock hole 113 of the base part 110. In this way, the male terminal 200 is connected to the female terminal 100.

  Hereinafter, the operation of each part of the floatin mechanism when the first and second substrates 10 and 20 are displaced in a state where the male terminal 200 is connected to the female terminal 100 will be described. FIG. 7 is a schematic plan view of the inter-terminal connection structure according to the embodiment of the present invention, and shows a state in which the first and second substrates are displaced, and FIG. FIG. 7 is a sectional view taken along the line CC in FIG. 7 and FIG. 7B is a sectional view taken along the line DD in FIG.

  As shown in FIG. 7, when the first substrate 10 is displaced in the X direction and the −Y direction, and the second substrate 20 is displaced in the −X direction and the Y direction, respectively, as shown in FIG. The portion 210 moves between the base portion 110 and the pressing portion main body 152 and between the side wall portions 120 in the direction between the −X direction and the Y direction, and the lock claw 211 of the head portion 210 is shown in FIG. As shown, the inside of the lock hole 113 of the base 110 moves in the direction between the −X direction and the Y direction. For this reason, the displacement of the first and second substrates 10 and 20 is allowed.

  When the first substrate 10 is displaced in the X direction and the Y direction, and the second substrate 20 is displaced in the −X direction and the −Y direction, the head portion 210 is located between the base portion 110 and the pressing portion main body 152 and the side wall portion 120. The lock claw 211 of the head part 210 moves in the lock hole 113 of the base part 110 in the direction between the -X direction and the -Y direction. For this reason, the displacement of the first and second substrates 10 and 20 is allowed.

  Further, when the first substrate 10 is displaced in the −Y direction and the second substrate 20 is displaced only in the Y direction, the head portion 210 is moved between the base portion 110 and the pressing portion main body 152 and between the side wall portions 120 in the Y direction. The lock claw 211 of the head portion 210 moves in the Y direction in the lock hole 113 of the base portion 110. For this reason, the displacement of the first and second substrates 10 and 20 is allowed.

  When the first substrate 10 is displaced only in the Y direction and the second substrate 20 is displaced only in the −Y direction, the head portion 210 is displaced in the −Y direction between the base portion 110 and the pressing portion main body 152 and between the side wall portions 120. The lock claw 211 of the head part 210 moves in the lock hole 113 of the base part 110 in the −Y direction. For this reason, the displacement of the first and second substrates 10 and 20 is allowed.

  When the first substrate 10 is displaced only in the X direction and the second substrate 20 is displaced only in the −X direction, the head portion 210 moves in the −X direction between the base portion 110 and the pressing portion main body 152, and the head portion The lock claw 211 of 210 moves in the -X direction in the lock hole 113 of the base 110. For this reason, the displacement of the first and second substrates 10 and 20 is allowed.

  Hereinafter, the operation of each unit will be described together with the procedure for connecting the male terminal 200 to the female terminal 100 described above. FIG. 9 is a schematic cross-sectional view showing a process of removing the male terminal from the female terminal.

  As shown in FIG. 9, the male terminal 200 is lifted together with the second substrate 20 with the tip of the head part 210 of the male terminal 200 (the part in contact with the base 110) as a fulcrum. Thereby, the head part 210 pushes up the pressing part main body 152 upward, and the pressing part 150 and the folding | returning part 140 elastically deform. As a result, a gap is generated between the head part 210 and the base part 110, and the lock claw 211 of the head part 210 comes out of the lock hole 113 of the base part 110. In this state, the head part 210 of the male terminal 200 is pulled out from between the pressing part main body 152 and the base part 110 of the female terminal 100. In this way, the male terminal 200 can be easily detached from the female terminal 100.

  The pressing portion main body 152 pushed upward by the head portion 210 abuts against the pair of stopper portions 131. For this reason, the further displacement of the press part main body 152 is prevented, and the more than predetermined elastic deformation of the folding | returning part 140 is also prevented.

  In the inter-terminal connection structure described above, when the head portion 210 of the male terminal 200 is inserted into the gap α between the pressing portion main body 152 and the base portion 110 of the female terminal 100, the head portion 210 is moved by the pressing portion main body 152. The state in which the lock claw 211 of the head part 210 is pushed into the lock hole 113 of the base part 110 is maintained by being pressed toward the base part 110. Since the head portion 210 is pressed toward the base portion 110 by the pressing portion main body 152 in this way, the male side terminal 200 is lifted in the direction away from the base portion 110 together with the second substrate 20. The lock claw 211 of the side terminal 200 comes out of the lock hole 113 of the base 110. Therefore, after that, the male terminal 200 can be removed from the female terminal 100 simply by pulling the head part 210 from between the pressing part main body 152 and the base part 110. Therefore, the removal of the male terminal 200 becomes very simple.

  Moreover, the floatin mechanism is constituted by a combination of the lock claw 211 and the lock hole 113. That is, the floatin mechanism is realized with a very simple configuration, and the displacement of the first and second substrates 10 and 20 can be allowed. In addition, since the head portion 210 is pressed by the pressing portion main body 152 and the state in which the lock claw 211 of the head portion 210 is engaged with the lock hole 113 of the base portion 110 is maintained, the head portion 210 may come off carelessly. In addition, the connection reliability can be improved. As described above, since the connection and removal of the male terminal 200 from the female terminal 100 are very easy while ensuring the floating function, the workability of the connecting action between the first and second substrates 10 and 20 is improved. Can be improved.

  Moreover, since both the female side terminal 100 and the male side terminal 200 are press-molded metal plates, they can be produced at low cost. Moreover, since it is only the female side terminal 100 and the male side terminal 200 and does not require the resin-made body etc. which accommodate this female side terminal 100 and the male side terminal 200, a number of parts can be reduced and low. The cost can be reduced and the height of the structure can be reduced.

  The inter-terminal connection structure is not limited to the above embodiment, and can be arbitrarily changed in design within the scope described in the claims. This will be described in detail below.

  In the above embodiment, the lock claw 211 is a rounded piece obtained by cutting and bending a part of the head part 210. However, as long as the lock claw 211 is a convex body that can be inserted into the lock hole of the base part of the female terminal. It is possible to change the design.

  Moreover, in the said embodiment, although the male side terminal 200 was supposed to have the six mounting parts 240, it is not limited to this. That is, it is possible to arbitrarily select and set how the male terminal 200 is mounted on the substrate. For example, the main body 230 may be solder-connected to the substrate.

  Moreover, in the said embodiment, although the male side terminal 200 had the bending part 230, it is not limited to this. That is, whether or not the bent portion 230 is provided is arbitrary.

  In the above embodiment, the lock hole 113 has the length dimension L1 and the width dimension W1 larger than the length dimension L2 and the width dimension W2 of the lock claw 211. The design can be arbitrarily changed as long as the hole is insertable. Further, only the length dimension L1 can be made larger than the length dimension L2, and the X direction in the lock hole 113 of the lock claw 211 can be moved. It can also be configured to be larger than the dimension W2 so that the lock claw 211 can move in the Y and −Y directions within the lock hole 113. The lock hole may be provided in the head portion of the male terminal, while the lock claw may be provided in the base portion of the female terminal. Even in this case, the same effect as that of the above embodiment can be obtained.

  In the above-described embodiment, the pressing portion 150 includes the arm 151 and the pressing portion main body 152 having a substantially V-shaped cross section. However, the head portion is bent between the base portion and the base portion. As long as the distance between the pressing portion and the base portion is smaller than the thickness dimension of the head portion, the design can be arbitrarily changed.

  In the above embodiment, the female terminal 100 has the side wall portion 120 and the flange portion 130. However, the present invention is not limited to this. That is, whether or not the side wall 120 and the flange 130 are provided is arbitrary.

  Moreover, although the said inter-terminal connection structure was provided with a pair of female | female side terminal 100 and the male side terminal 200, what is necessary is just to provide the female | female side terminal 100 and the male side terminal 200 at least one each.

  In the above embodiment, the female terminal 100 is mounted on the first substrate 10 and the male terminal 200 is mounted on the second substrate 20, but the present invention is not limited to this. For example, it is possible to provide a connection part to which a cable such as a coaxial cable is connected to the female side terminal and the male side terminal. Of course, it is also possible to provide the connecting portion on one of the female side terminal and the male side terminal and mount the other on the substrate.
