  SUMMARY OF THE INVENTION In view of the above problems, the present invention is a male type terminal capable of preventing sliding rotation of the tab due to vibration or the like in a state where the tab is inserted into the tab inserting portion of the female type terminal, and tab insertion corresponding to the tab It is an object of the present invention to provide a connection structure in which the tab is inserted into a female terminal provided with a part.

  The present invention is a male terminal provided with a tab inserted and connected to a tab insertion portion in which a tab insertion space is formed in a female terminal, the tab being in the insertion direction to the tab insertion portion. A contact portion configured to be long and in contact with the elastic contact portion provided in the tab insertion portion is provided on one side in a plate thickness direction intersecting the insertion direction, and the other side is the one side from the other side A restriction recess which is concave toward the bottom and which is provided at a position facing the elastic contact portion of the tab insertion portion and which is positionally regulated in contact with a protrusion projecting toward the elastic contact portion It is characterized by

  Further, the present invention is a connection structure in which a male terminal having a tab and a female terminal having a tab insertion portion in which a tab insertion space into which the tab is inserted is formed are connected, The tab inserting portion is provided at a position facing the elastic contact portion provided on one side in the plate thickness direction intersecting the insertion direction in which the tab is inserted and the elastic contact portion on the other side in the plate thickness direction A protrusion protruding toward the elastic contact portion, the tab being long in the insertion direction, a contact portion contacting the elastic contact portion, and the other side from the other side toward the one side A recessed portion is provided, and a control recess is provided which is in contact with the projecting portion to control the position.

The restriction recess has a configuration in which it is recessed in an arc shape in the thickness direction as viewed from the insertion direction, or a configuration in which it is recessed in a trapezoidal shape that extends from one side to the other in the thickness direction Including recessed structures.
For example, in the case where the tab insertion portion is constituted by a housing, the elastic contact portion extends one surface of the housing toward the distal end side in the insertion direction, and the cross section along the insertion direction is curved. It includes a configuration in which the distal end portion is folded back to the base end side and stored in the inside of the tab insertion portion, a configuration in which a part of the surface constituting the tab insertion portion is pushed up into the tab insertion space, and the like.

  The protrusion is formed in a substantially semicircular cross-sectional shape or a substantially rectangular cross-sectional shape as viewed from an insertion direction called a bead, and a protrusion formed to have a length along the insertion direction, or the restriction It includes a projecting portion or the like which is protruded toward the one side from a portion where it is desired to abut on the concave portion.

  The above-mentioned opposing position is not limited to the case where the projecting portion and the elastic contact portion are disposed facing each other, and the projecting portion is disposed so as to be separated in the front and back of the insertion direction of the elastic contact portion. Also includes.

According to the present invention, in the state where the tab is inserted into the tab insertion portion of the female terminal, sliding rotation of the tab due to vibration or the like can be prevented.
More specifically, in a state in which the tab is inserted into the tab insertion portion, the tab abuts against the elastic contact portion on one side and is pressed to the other side, and the projection is formed in the restriction recess provided on the other side. It will contact.

Therefore, the tab is fixed by the elastic contact portion and the protrusion, and the protrusion abuts on the restriction recess recessed from the other side to the one side. As a result, even if an external force that slides and rotates with the contact point of the elastic contact portion and the contact portion as a rotating shaft is applied, since the restriction recess and the projecting portion are in contact, the slide of the tab It can regulate the rotation.
Accordingly, sliding rotation of the tab due to vibration or the like can be prevented, and abrasion of the contact point between the tab and the elastic contact portion can be prevented.

As an aspect of the present invention, the restricting recess may have a pair of inclined portions which spread from the one side toward the other side and abut against the projecting portion so as to be pinched.
The inclined portion may be formed in a straight or curved shape.

According to the present invention, sliding rotation of the tab can be reliably prevented.
For example, when only the bottom portion forming the restriction recess and the protrusion are in contact with each other, the elastic contact portion and the tab held by the protrusion are orthogonal to the rotational direction of sliding rotation due to vibration. The external force due to the pressing of the elastic contact portion acts only in the direction of That is, the sliding rotation due to the vibration is prevented by the frictional force.

  On the other hand, the protrusion has the inclined portion and the restricting recess includes a pair of inclined portions which spread from the one side toward the other side and abut against the protruding portion. Even when an external force is applied to the tab in the sliding rotational direction in a state in which the tab abuts, the projection which is in contact with the restriction recess directly receives the external force for slidingly rotating the tab. Sliding rotation of the tab can be prevented.

Further, as an aspect of the present invention, the central portion on the one side of the tab may be formed of a flat portion parallel to the insertion direction and a width direction intersecting the plate thickness direction.
According to the present invention, since the elastic contact portion can be accurately brought into contact with the flat portion, an elastic force acting from one side to the other side by the elastic contact portion can be reliably transmitted to the tab. Therefore, the tab can be reliably held between the elastic contact portion and the projection, and the projection can be reliably abutted on the restriction recess, and stable conductivity can be ensured.

  Further, as an aspect of the present invention, the tab is formed from the other side in the plate thickness direction from the base body provided with the contact portion and the restriction recess and both end portions in the width direction of the base body. It may be comprised with the leg extended toward one side.

According to the present invention, the rigidity of the tab can be improved. Thereby, the length of the width direction of the tab can be shortened, and the connector provided with the male terminal can be miniaturized.
Further, when the tab is inserted into the tab insertion portion, the leg guides the insertion of the tab along the wall portion forming the tab insertion portion, and the tab is easily inserted into the tab insertion portion. it can. Therefore, even if the male terminal and the female terminal are miniaturized, the insertion work of the tab can be performed easily and reliably.

As an aspect of the present invention, the base body may be formed to have a substantially V-shaped cross section, and the base body and the leg portion may be formed to have a substantially M-shaped cross section.
The cross section refers to a cross section cut in a plane orthogonal to the insertion direction in the tab extending in the insertion direction, and not only a cross section in the contact portion that contacts the elastic contact portion, but also in the contact portion The range including the front end side and the rear end side of the insertion direction is included. In other words, the cross sections of the proximal end and the distal end of the tab do not have to be substantially V-shaped.

  In the substantially V shape, when the facing oblique sides form a vertex, or when the contact portion between the facing oblique sides is curved, the insertion direction and the width direction intersecting the plate thickness direction are taken along Including the case where the diagonal sides facing each other in a straight line are connected. That is, the case where the shape of the said contact part applicable to the vertex part of V character is square shape, circular arc shape, and planar shape in the insertion direction view is included.

  According to the present invention, since the contact portion can be disposed so as to protrude to the one side, the elastic contact portion and the tab can be more reliably abutted. Therefore, the tab can be more reliably pressed to the other side, and the projection and the restriction recess can be reliably abutted.

  Further, since the leg portion extending from the other side in the thickness direction toward the one side is provided at both ends of the base body having a substantially V-shaped cross section, the rigidity of the tab can be improved. Thereby, the length in the width direction of the tab can be shortened, and the connector can be miniaturized. Further, since the rigidity can be improved, the thickness of the tab can be reduced, and the weight can be reduced.

  Furthermore, since the leg portion functions as a guide for the wall portion forming the tab insertion portion when the leg portion is inserted into the tab insertion portion, the tab can be easily inserted into the tab insertion portion. As a result, even if the male terminal and the female terminal are miniaturized, the tab can be inserted easily and reliably.

Further, as an aspect of the present invention, the one end side end of the leg may be disposed closer to one end than the one end side end of the base body.
According to the present invention, the rigidity of the tab can be further improved, and the inserting operation of the tab can be more easily and reliably performed.

  Further, the one end side end portion of the leg portion is disposed closer to the one end side than the one end side end portion of the base body, so that the leg portion arranges the elastic contact portion at a central portion of the tab. It can be guided and the tab can be more easily inserted into the tab insert.

Further, as an aspect of the present invention, the tab may have a connecting portion that connects the end portions on one side of the leg portion along the width direction.
According to the present invention, since the rigidity of the tab can be further improved, the miniaturization of the male terminal can be further coped with.

As a mode of the present invention, it is constituted by a base by which the above-mentioned contact part and the above-mentioned regulation crevice were provided, and a section may be formed in the shape of an approximately V character in the above-mentioned base.
According to the present invention, since the contact portion protrudes to the one side, the elastic contact portion can be more reliably abutted on the contact portion. Thereby, since the said tab can be pressed on the other side more reliably, the said protrusion part and the said control recessed part can be made to contact reliably. Therefore, while being able to prevent the sliding rotation of the said tab, a male type | mold terminal and a female type | mold terminal can be electrically connected reliably.

  The present invention is also a male connector comprising the above-mentioned male terminal and a housing on which the male terminal is mounted, wherein the male terminal has a length in the width direction of the tab which is the same as that of the male terminal. It may be longer than the length in the thickness direction, and a large number of the male terminals may be arranged along the thickness direction more than the width direction.

  According to the present invention, the length in the width direction is smaller than the length in the plate thickness direction than in the case where a large number of male type terminals are arranged along the width direction, it is compact with respect to the number of the male type terminals arranged. You can Therefore, as in recent years, it is possible to solve the problems such as space saving inside the vehicle and an increase in terminals with respect to an increase in electronic devices.

  Here, in FIG. 1, the longitudinal direction of the connection structure 1 is an insertion direction L, the width direction of the connection structure 1 is a plate thickness direction T, and the vertical direction is a width direction W. The insertion direction L, the thickness direction T, and the width direction W are orthogonal to each other.

  Further, along the insertion direction L in FIG. 1, the left direction is the + L direction, and the right direction is the −L direction. Similarly, the left direction is -T direction and the right direction is + T direction along the thickness direction T in FIG. 1, and the upper direction is + W direction and the lower direction is -W direction along the width direction W in FIG. The same applies to FIG. 2 and thereafter.

As shown in FIG. 1, the connection structure 1 has a male type terminal 2 for connecting the base end side (−L direction side) to the substrate, and a coated electric wire 100 connected to other devices not shown. While being able to insert from + L direction side, it comprises with female type terminal 3 into which male type terminal 2 is inserted from the base end side (-L direction side).
In addition, the covered electric wire 100 is comprised with the conductor 110 which has electroconductivity, and the insulation coating 120 which covered the outer periphery of the insertion direction L of the conductor 110, and it shows with a broken line in FIG.

  As shown in FIGS. 2 to 4, the male terminal 2 has a conductive tab 10 elongated along the insertion direction L, and a tab connection provided on the proximal end side (-L direction) of the tab 10. The portion 20 and the bus bar terminal portion 30 extending in the −L direction from the base end of the tab connection portion 20 are integrally formed in this order from the + L direction of the insertion direction L.

  The tab 10 is configured to be long along the insertion direction L, and is formed of a conductive metal plate formed so as to be insertable to the female terminal 3 from the −L direction, and along the width direction W The base body 11 thus formed and the leg portions 12 extending in the −T direction from both end portions on the width direction W side of the base body 11 are integrally configured.

  As shown in FIG. 4A, the base body 11 is configured such that the tip end side (+ L direction side) and the base end side (−L direction side) become narrower in the width direction W, It is a substantially V-shaped plate-like body.

  In addition, as shown in a cross section orthogonal to the insertion direction L in the central portion of the insertion direction L of the base body 11 (see FIG. 4B), the + T side surface of the base body 11 is from the + T side to the −T side A restricting recess 13 for forming a concave shape is formed along the insertion direction L of the base body 11, and a protrusion 14 projecting to the -T side is in the insertion direction L on the surface on the -T side of the base body 11. It is formed along.

As shown in FIG. 4C, the restriction recess 13 is a pair of inclined surfaces inward in the width direction W from the both ends in the width direction W of the base body 11 toward the −T side. And the concave side flat part 132 which connects the edge parts by the side of -T of concave side inclined part 131. As shown in FIG. In other words, the control recess 13 is a concave recess that spreads from the −T direction side toward the + T direction side.
In addition, in this embodiment, although the concave side inclined part 131 is made into the curve shape curved so that it might become convex shape to the -T direction side, it is good also as linear shape not only in this shape.

The convex portion 14 formed by forming the restricting concave portion 13 is a pair of sloped surfaces which are inward in the width direction W toward the −T side at a position facing the concave side sloped portion 131. It is comprised by the convex side plane part 142 which is a plane parallel to the width direction W which connects the part 141 and the -T side edge part of the convex side inclination part 141. As shown in FIG.
The base body 11 thus configured has a substantially V-shaped cross section in the insertion direction obtained by cutting the central portion of the base body 11 perpendicularly to the insertion direction L, and can be easily manufactured by press processing or the like.

  The leg portions 12 extending in the −T direction from both ends in the width direction W of the base body 11 are plate members having the same plate thickness as the base body 11 and are provided on the tip end side (−T direction end portion) of the leg portions 12 A certain leg bottom surface 121 is disposed on the −T direction side of the convex side flat portion 142. In other words, the length L1 of the leg portion 12 in the thickness direction T is the length L2 of the base body 11 in the thickness direction T (in the base body 11 formed in a substantially V-shaped cross section The length from the + T side end to the -T side end of the convex side flat portion 142 is longer than the length T).

  Further, the length L1 of the leg portion 12 in the plate thickness direction T is shorter than the length W1 of the base body 11 in the width direction W. That is, the insertion direction cross section which cut | disconnected the center part of the tab 10 perpendicularly | vertically with respect to the insertion direction L becomes a substantially M shape long to the width direction W. As shown in FIG. For this reason, the rigidity of the tab 10 is improved as compared to a flat tab having the same thickness and width.

  The bus bar terminal portion 30 is a bus bar integrally formed with the tab 10 through the tab connecting portion 20, and the bar bar connecting portion 31 extending in the −L direction from the base end side of the tab connecting portion 20; Integrated at the -L side end with a bent portion 32 slightly bent on the + T side and extended in the -W direction, and a bus bar 33 connected to the bent portion 32 and connected to a substrate or the like of another device It is done.

  The female type terminal 3 is a hollow elongated cylindrical body formed of a metal member as shown in FIG. 5A, and is connected to the terminal connection portion 40 to be connected to the male type terminal 2 and the coated electric wire 100. The wire connection portions 50 are arranged in this order from the rear end side (−L direction side) to the front end side (+ L direction side).

  The terminal connection portion 40 is constituted by a tab insertion side cylindrical portion 41 formed of a slender cylindrical body having a rectangular cross section into which the tab 10 of the male terminal 2 is inserted, and the −L side of the tab insertion side cylindrical portion 41 An open end 411 which is an open end is formed at the end (see FIG. 3), and a tab insertion space S into which the tab 10 can be inserted is formed inside the tab insertion side cylindrical portion 41. In addition, an elastic contact portion 42 and a bead 43 are provided on the inner peripheral surface of the central portion of the tab insertion side cylindrical portion 41 (see FIG. 5B).

  The open end 411 is formed in a substantially square shape in a front view, and the width length is one length longer than the length W1 which is the width length in the tab 10, and the length in the plate thickness direction T is the tab 10 (leg portion 12) The length L1 of the plate thickness direction T is approximately twice as long as the length L1.

As shown in FIGS. 5B and 5C, the elastic contact portion 42 is a connecting end whose one end is connected to the tip end side of the bottom surface 41a which is the -W side inner peripheral surface of the tab insertion side cylindrical portion 41. A contact state between the free end 422 located at the base end side of the bus bar terminal 30 of the tab insertion side cylinder 41 and the other end of the section 421 and the inner surface of the bottom surface 41a on the + L side of the free end 422 is maintained. A so-called cantilevered plate-like body provided with the tongue piece supporting portion 423 configured as described above, and abut on the inserted tab 10 between the connecting end 421 and the free end 422 A tongue contact portion 44 (dimple) for electrically connecting the male terminal 2 and the female terminal 3 is provided to project to the + T side.
In addition, the convex side flat part 142 in the tab 10 is arrange | positioned rather than the vertex of the tongue piece contact part 44 at the time of insertion at the-T direction side.

  The elastic contact portion 42 configured in this way has a free end 422 that is a free end, but supports the elastic contact portion 42 with respect to the bottom surface 41 a by the connecting end 421 and the tongue support 423. It is a point support structure and can generate a sufficiently large elastic force that can resist the contact pressure of the inserted tab connection 20.

  The bead 43 is a protrusion which protrudes from the upper surface 41b which is the inner peripheral surface of the tab insertion side cylinder 41 facing the bottom surface 41a toward the tongue contact portion 44, that is, toward the -T side. The outer peripheral surface on the + T side of the insertion side cylindrical portion 41 is formed by pressing in the -W side direction.

  The bead 43 has a substantially elliptical shape in plan view provided in a predetermined range of the insertion direction L of the free end 422 at a position facing the tongue contact portion 44 provided at the central portion of the elastic contact portion 42 in the insertion direction L. Of the distal end side projecting portion 432 and the proximal end side projecting portion 433 on the front and rear end side (± L direction side) of the elastic contact portion 42 with respect to the central projecting portion 431 which is a projecting portion of the shape. One protrudes to the -W side.

  The wire connection portion 50 is constituted by a distal end side cylindrical portion 51 which is a slender cylindrical body having a rectangular cross section and extending from the distal end side (+ L direction side) of the terminal connection portion 40. The (−L side end) is connected to the tip (+ L side end) of the tab insertion side cylindrical portion 41.

  Further, the distal end portion of the distal end side tubular portion 51 is provided with an open rectangular distal end side open end 511 (see FIG. 2), and a wire arrangement space U formed inside the wire connection portion 50 is formed. It is done. The front end side opening end 511 is formed in a square shape in front view smaller than the opening end 411 (not shown).

  The wire connection portion 50 configured in this manner passes the conductor 110 exposed by peeling off the insulating coating 120 of the coated wire 100 from the + L direction through the distal end side open end 511, and the conductor 110 in the wire arrangement space U Can be placed. Further, the conductor 110 inserted through the distal end side open end 511 is sandwiched from the width direction W side by the elastic sandwiching pieces 52 provided at both ends in the width direction W of the wire connection portion 50, with respect to the wire connection portion 50. It is electrically and mechanically fixed and disposed in the wire arrangement space U.

Hereinafter, the connection state of the connection structure 1 in which the male terminal 2 and the female terminal 3 are connected by inserting the tab 10 into the terminal connection portion 40 will be briefly described based on FIGS. 6 to 8.
Here, FIG. 6 shows an enlarged side view of the terminal connection portion 40 in the connection structure 1 in which the male terminal 2 and the female terminal 3 are connected, as viewed from the + T direction side, and FIG. 7 and FIG. The sectional view in the position where 2 and female type terminal 3 were made to contact is shown.

Specifically, FIG. 7 (a) shows a cross-sectional view taken along the line C-C in FIG. 6, FIG. 7 (b) shows a cross-sectional view taken along the line D-D in FIG. 6, and FIG. 8 shows a cross-sectional view taken along the line E-E in FIG. Indicates
7 and 8, the tab connecting portion 20 and the bus bar terminal portion 30 are omitted for the sake of convenience.

  As shown in FIG. 6, the tab 10 can be inserted into the terminal connection portion 40 by pushing the tab 10 from the open end 411 to + L. At this time, the legs 12 constituting the tab 10 are parallel to the side surface 41 c constituting the opening end 411. Further, since the insertion direction L1 of the leg 12 is about half the length of the open end 411, the leg 12 functions as a guide at the time of insertion into the tab insertion cylindrical portion 41.

  Further, since the insertion direction L1 which is the length of the legs 12 is longer than the length L2 in the thickness direction T of the base body 11, the elastic contact portion 42 is disposed between the legs 12 . Thus, the leg portion 12 also functions as a guide such that the resilient contact portion 42 is disposed at the central portion in the width direction W of the tab 10.

  Thus, the tab 10 inserted into the terminal connection portion 40 with the leg portion 12 as a guide is inserted to the vicinity of the tip end of the terminal connection portion 40 and is held between the resilient contact portion 42 and the bead 43 It is fixed to the insertion space S.

  More specifically, when the tongue contact portion 44 provided on the elastic contact portion 42 and the tab 10 are in contact with each other, the tongue contact portion 44 functions as an abutment as shown in FIG. 7A. It abuts on the convex side flat portion 142. At this time, since the elastic contact portion 42 has elasticity, the elastic contact portion 42 presses the tab 10 in the + T direction, and the tab 10 and the terminal connection portion 40 are made conductive.

  On the other hand, since the central projection 431 has a smaller amount of projection than the distal end projection 432 and the proximal end projection 433, in this position where the tongue contact portion 44 and the tab 10 abut And the central protrusion 431 are not in contact with each other.

  On the other hand, on the tip end side (+ L direction side) of the position at which the tongue contact portion 44 and the tab 10 abut, as shown in FIG. The distal end side projecting portion 432 is in contact with the pair of concave side inclined portions 131 in two places. More specifically, the concave inclined portion 131 is in contact with the distal projection 432 at a position substantially symmetrical in the width direction W. That is, the concave inclined portion 131 is in contact with the tip end projecting portion 432 so as to sandwich the bead 43 at a substantially symmetrical position.

  Therefore, even if the tab 10 is about to slide and rotate about the contact portion between the tongue contact portion 44 and the convex side flat portion 142 as the rotation center, the tip that is in contact with the concave side inclined portion 131 The side projection portion 432 exerts a reaction in the direction opposite to the rotational direction of the sliding rotation (horizontal direction with respect to the thickness direction T), so that the sliding rotation of the tab 10 can be reliably prevented.

  Further, since the tongue contact portion 44 pushes up the tab 10 to the + T side by an elastic force, an external force acts on the contact point between the concave side inclined portion 131 and the base end side projecting portion 433 and the tab 10 and the terminal The connection portion 40 can be made conductive.

  Similarly, on the base end side (−L direction side) of the position at which the tongue contact portion 44 and the tab 10 abut, as shown in FIG. The base end side projecting portions 433 are in contact at two positions so as to be sandwiched between the concave side inclined portions 131 as a pair.

Therefore, even if the tab 10 is about to slide and rotate about the contact point between the tongue contact portion 44 and the convex side flat portion 142, the base end in contact with the concave side inclined portion 131 The side protrusions 433 exert a drag in the direction opposite to the rotational direction of the sliding rotation (horizontal direction with respect to the thickness direction T), so that the sliding rotation of the tab 10 can be reliably prevented.
In addition, an external force acts on the contact point between the concave inclined portion 131 and the proximal end projecting portion 433 so that the tab 10 and the terminal connection portion 40 can be reliably brought into contact with each other to conduct electricity.

  As described above, in the present embodiment, the concave inclined portion 131 and the bead 43 (the distal end side projecting portion) on the distal end side and the proximal end side in the insertion direction L of the abutment point between the tongue contact portion 44 and the convex side flat portion 142 432 and the proximal end projecting portion 433) are in contact at four points, and the distal end projecting portion 432 and the proximal end projecting portion 433 are a pair of concave sides that are substantially symmetrical in the width direction W Since it is in contact with the inclined portion 131, the sliding rotation of the tab 10 centering on the contact point with the tongue contact portion 44 can be prevented more reliably.

The male terminal 2 configured in this way is used, for example, in a male connector 500 to be connected to the connector-equipped wire harness 200 as shown in FIGS. 9 and 10.
Here, FIG. 9 shows a schematic perspective view of the wire harness 200 with a connector and the male connector 500, and FIG. 10 shows the rear cover 430 and the housing case 420 of the wire harness 200 with a connector, and the male housing 510 of the male connector 500 in broken lines. The rear cover 430, the housing case 420, and the connector-equipped wire harness 200 and the male connector 500 shown in FIG. The vertical direction in FIGS. 9 and 10 is taken as the vertical direction Z.

  As shown in FIG. 9, the connector-equipped wire harness 200 is configured by connecting a female connector 400 to the tip of the wire harness 300 in which the coated electric wire 100 is bundled. The wire harness with connector 200 and the male connector 500 can be mounted on a vehicle (for example, an automobile) and used.

  The female connector 400 includes a plurality of female terminals 3 connected to the coated wire 100, a housing 410 on which the plurality of female terminals 3 are mounted, and a housing case 420 for housing the housing 410 from the front side of the housing. , And a rear cover 430 attached to the housing case 420 so as to accommodate the end of the bundle of the covered electric wire 100 drawn from the rear end of the housing 410, for example, to electronic devices mounted on a vehicle It is configured to be connectable with the fixed male connector 500.

  Male connector 500 is, as shown in FIG. 10, a male housing 510 for housing male terminal 2 arranged to correspond to female terminal 3 attached to female connector 400 and male terminal 2. And consists of. The male terminal 2 accommodated in the male housing 510 is disposed such that the width direction W of the tab 10 is along the vertical direction Z. In addition, male terminal 2 arranges 5 sets (3 sets in the lower part and 2 sets in the upper part) in male type housing 510, with a total of 16 pieces of 8 in the thickness direction T and 2 rows in the width direction W as one set. doing.

  Thus, in the male connector 500 in which the male terminals 2 are arranged, the male terminals 2 arranged along the width direction W of the tab 10 along the vertical direction Z are arranged along the thickness direction T more than the width direction W As compared with the case where a large number of male terminals 2 arranged in the thickness direction T along the vertical direction Z are arranged along the width direction W, for example, a large number of male terminals 2 are arranged. The size of the mold connector 500 can be miniaturized.

  The male terminal 2 configured in this manner includes the tab 10 inserted and connected to the terminal connection portion 40 in which the tab insertion space S is formed in the female terminal 3. The tab 10 is a terminal connection portion 40. A convex side flat portion configured to be long in the insertion direction L to the insertion side, and in contact with the elastic contact portion 42 provided on the terminal connection portion 40 on one side (−T direction side) of the plate thickness direction T intersecting the insertion direction L 142 is provided, is concave on the other side (+ T direction side) from the other side toward one side, and is directed to an elastic contact portion 42 provided at a position facing the elastic contact portion 42 of the terminal connection portion 40 By providing the regulating recess 13 which is positionally regulated in contact with the projecting bead 43, the sliding rotation of the tab 10 due to vibration or the like can be performed in a state where the tab 10 is inserted into the terminal connection portion 40 of the female terminal 3. It can prevent.

  More specifically, in the state where the tab 10 is inserted into the terminal connection portion 40, the tab 10 is in contact with the elastic contact portion 42 and is pressed to the other side, and the bead 43 is in contact with the regulating recess 13 provided on the other side. It will be in contact with you.

  Therefore, the tab 10 is held by the elastic contact portion 42 and the bead 43 and fixed, and the bead 43 abuts on the regulating recess 13 depressed from the other side to the one side, and the elastic contact portion 42 and the convex side plane Even if an external force acts so as to slide and rotate with the contact point of the portion and 142 as the rotation axis, the regulating recess 13 and the bead 43 come in contact, and the sliding rotation of the tab 10 can be regulated. Therefore, the sliding rotation of the tab 10 due to vibration or the like can be prevented, and the contact between the tab 10 and the elastic contact portion 42 can prevent the wear.

  Further, the restricting recess 13 spreads from one side to the other side, and has a pair of concave side inclined portions 131 which abut against the bead 43 so that the tab 10 slides and rotates reliably. Can be prevented.

  More specifically, even if an external force is applied to the tab 10 in the sliding rotation direction in a state where the bead 43 is in contact with the concave side inclined portion 131, the bead 43 in contact with the restriction recess 13 directly slides the tab 10 It will receive the external force to rotate, and the sliding rotation of the tab 10 can be prevented more reliably.

  In addition, the elastic contact portion 42 is configured by forming the central portion on one side of the tab 10, that is, the convex side flat portion 142 parallel to the width direction W intersecting the insertion direction L and the thickness direction T. The elastic force that acts from one side to the other side by the elastic contact portion 42 can be reliably transmitted to the tab 10 by accurately contacting the convex side flat portion 142. Therefore, the tab 10 can be reliably held between the resilient contact portion 42 and the bead 43.

  Furthermore, it is comprised by the base body 11 in which the convex side plane part 142 and the control recessed part 13 were provided, and the convex side plane part 142 is provided by the cross section being formed in a substantially V shape. Since it protrudes to the -T direction side, the elastic contact portion 42 can be more reliably abutted against the convex side flat portion 142, and the tab 10 can be more reliably pressed to the + T direction side. Therefore, the bead 43 and the control recess 13 can be reliably abutted.

  Further, the tab 10 is directed from the other side in the plate thickness direction T to one side from the base body 11 provided with the convex side flat portion 142 and the restriction recess 13 and both end portions in the width direction W in the base body 11 The rigidity of the tab 10 can be improved and the length in the width direction W of the tab 10 can be shortened by being configured by the extending legs 12. Thereby, the connector provided with the female terminal 3 can be miniaturized.

  Furthermore, when the tab 10 is inserted into the terminal connection portion 40, the tab 10 can be easily inserted into the terminal connection portion 40 because the leg portion 12 guides along the wall portion forming the terminal connection portion 40. Thus, even if the male terminal 2 and the female terminal 3 are miniaturized, the tab 10 can be inserted easily and reliably.

  Further, the base body 11 has a substantially V-shaped cross section, and the M-shaped cross section of the base body 11 and the leg portion 12 makes the convex side flat portion 142 in the -T direction side. The resilient contact portion 42 and the tab 10 can be abutted more reliably. Therefore, the tab 10 can be more reliably pressed to the other side, and the bead 43 and the control recess 13 can be reliably abutted.

  Further, since the legs 12 extending from the other side to the one side in the thickness direction T are provided at both ends of the base body 11 having a substantially V-shaped cross section, the rigidity of the tab 10 can be improved. Thereby, the length of the width direction W of the tab 10 can be shortened, and the connector can be miniaturized. Further, since the rigidity can be improved, the thickness of the tab 10 can be reduced, and the weight can be reduced.

  Furthermore, since the leg portion 12 functions as a guide for the wall portion forming the terminal connection portion 40 when the leg portion 12 is inserted into the terminal connection portion 40, the tab 10 can be easily inserted into the terminal connection portion 40. Thus, even if the male terminal 2 and the female terminal 3 are miniaturized, the tab 10 can be inserted easily and reliably.

  Further, one end side end (−T direction side end) of the leg 12 is closer to the −T direction than the one end side end (−T direction side end surface) of the convex side flat portion 142 constituting the base body 11 By being disposed, the rigidity of the tab 10 can be further improved, and the tab 10 can be inserted more easily and reliably because it functions as a guide for the wall forming the terminal connection portion 40. it can.

  Furthermore, by arranging the one end side end of the leg 12 to be closer to one end than the one end side of the base body 11, the leg 12 arranges the elastic contact portion 42 in the central portion of the tab. And the tab 10 can be more easily inserted into the terminal connection 40.

  The male connector 500 is composed of the male terminal 2 and the male housing 510 to which the male terminal 2 is mounted, and the male terminal 2 has a length in the width direction W of the tab 10 The length in the width direction W is longer than the length in the plate thickness direction T by being configured to be longer than the length in the thickness direction T and a large number of male terminals 2 are arranged along the plate thickness direction T than the width direction W. Also, as compared with the case where a large number of male terminals 2 are arranged along the width direction W, the number of arranged male terminals 2 can be made compact. Therefore, as in recent years, it is possible to solve the problems such as space saving inside the vehicle and an increase in terminals with respect to an increase in electronic devices.

In correspondence with the configuration of the present invention and the above-described embodiment,
The tab insert corresponds to the terminal connection 40,
The contact portion corresponds to the convex side flat portion 142,
The protrusions correspond to the beads 43,
The slope corresponds to the concave slope 131,
The flat portion corresponds to the convex side flat portion 142,
The housing corresponds to male housing 510 and the male connector corresponds to male connector 500,
The present invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.

  For example, in the present embodiment, the restriction recess 13 is formed to be recessed in a circular arc shape in the −T direction side when viewed from the insertion direction L, but for example, it goes from the −T direction side to the + T direction side The configuration may be a configuration that is formed to be recessed in a trapezoidal shape that spreads out, a configuration that is recessed in a rectangular shape, or the like.

  In addition, the elastic contact portion 42 extends one surface (bottom surface 41 a) of the tab insertion side cylinder portion 41 configured by the housing to the −L direction side, and the section along the insertion direction L is curved, The L direction side end may be folded back to the + L direction side to be housed inside the terminal connection portion 40. That is, the elastic contact portion 42 may have any shape as long as it is configured to press the tab 10 inserted into the terminal connection portion 40 to the + T direction side by an elastic force.

  Further, as in the present embodiment, the bead 43 in contact with the restricting recess 13 is a beat in which the surface on the + T direction side of the tab insertion side cylindrical portion 41 is recessed in the −T direction. It may be a projection which is made to project in the -T direction side at the point where it abuts.

  In the present embodiment, the concave inclined portion 131 abuts on the bead 43 (the distal end side projecting portion 432 and the proximal end side projecting portion 433) at four locations, but it is not necessary to be four locations. It may be in contact at a place (the distal end side projecting portion 432 or the proximal end side projecting portion 433), or the central projecting portion 431 may be in contact with the concave side inclined portion 131.

  In addition, the tab 10 is stably brought into contact at three points of the concave inclined portion 131 in contact with the distal end side projecting portion 432 and the proximal end side projecting portion 433 and the convex side flat portion 142 in contact with the tongue piece abutting portion 44. Thus, the electrical connection between the male terminal 2 and the female terminal 3 can be reliably realized.

  Further, in the present embodiment, as shown in FIG. 4B, the cross section in the insertion direction L of the tab 10 is configured to be substantially M-shaped, but for example, as shown in FIG. The insertion direction L cross section without the leg 12 may be configured to be substantially V-shaped.

  Here, FIGS. 11A and 11B show a cross-sectional view taken along the line C-C in FIG. 6 in another embodiment of the male type terminal 2.

  Thereby, since the convex side plane part 142 protrudes to the-T direction side, the elastic contact part 42 and the tab 10 can be contacted more reliably. Moreover, the tab 10 can be more reliably pressed to the + T direction side, and the bead 43 and the control recess 13 can be reliably abutted.

Furthermore, as shown in FIG. 11B, the insertion direction L section provided with the connecting portion 15 connecting the -T side end portions of the leg portions 12 may be configured to be substantially B-shaped. Thereby, since the rigidity of the tab 10 can be further improved, the male type terminal 2 can be further miniaturized.
However, since the tab 10 can be reliably abutted against the tongue contact portion 44 and the bead 43 while the tab 10 has appropriate strength in the case of the M-shaped cross section, the substantially V-shaped cross section It is preferable to the cross-sectional B-shape.

  Moreover, although the bus bar terminal part 30 is connected with the base end side (-L direction side) of the tab 10 in the male type terminal 2, it connects with the crimping part which crimps the covered electric wire 100 instead of the bus bar terminal part 30, for example. You may. Similarly, although the wire connection portion 50 is connected to the tip end side (+ L direction side) of the terminal connection portion 40 in the female terminal 3, a crimped portion or a connector for crimping the coated wire 100 instead of the wire connection portion 50 You may connect the accommodating part etc. which can be accommodated in a box. That is, components to be connected to the proximal end side of the tab 10 and the distal end side of the terminal connection portion 40 can be appropriately selected.
