The conventional connector terminal 501 described above does not require a structure for improving the holding force of the connector terminal 501 in the locking lance 507 of the connector housing 503, and the connector housing 503 can be reduced in size and locked. The holding force by the lance 507 can be improved.
However, the terminal housing chamber 505 of the connector housing 503 needs to secure a space for installing the locking lance 507 outside the connector terminal 501. For this reason, particularly in a connector in which a plurality of connector terminals 501 are attached to the connector housing 503, the installation space S must be secured by the number of the locking lances 507, and downsizing of the connector still remains as a problem.

Embodiments according to the present invention will be described below with reference to the drawings.
As shown in FIG.1 and FIG.2, the terminal 11 provided with the terminal structure which concerns on one Embodiment of this invention has the board | substrate part 15, the bending piece part 17, and the latching | locking part 19 as main structures. Prepare.

  The terminal 11 according to the present embodiment is inserted in the terminal insertion direction along the axis 25 of the terminal accommodating chamber 23 with respect to the terminal accommodating chamber 23 of the connector housing 13 (see FIG. 3) having a prismatic terminal accommodating space 21. The The terminal housing chamber 23 formed in the connector housing 13 opens as a terminal insertion port 29 on the housing rear end surface 27 and opens as a mating terminal receiving port 33 on the housing front end surface 31. These terminals 11 and the connector housing 13 constitute a connector 35 (see FIG. 7). The terminal 11 is formed by bending a single punched workpiece 37 obtained by punching a conductive metal plate (see FIG. 4). As a material of the metal plate, in addition to a copper alloy or an aluminum alloy, phosphor bronze having a spring property can be preferably used.

  The connector housing 13 according to the present embodiment is obtained by injection molding an insulating synthetic resin. FIG. 3 illustrates the connector housing 13 in the case of two poles. In the connector housing 13, one terminal accommodating chamber 23 is formed for each pole. The connector housing 13 is formed in a rectangular parallelepiped shape, and two terminal accommodating chambers 23 each having a prismatic terminal accommodating space 21 in a direction along the axis 25 in the longitudinal direction of the rectangular parallelepiped shape are arranged in a direction perpendicular to the axis 25. (It is installed side by side.) Of course, the connector housing 13 may include only one terminal accommodating chamber 23.

  The terminal 11 according to the present embodiment has a substrate part 15 as a base part. The substrate portion 15 is in contact with one reference inner wall surface 39 of the terminal accommodating chamber 23 in a parallel state. Here, the reference inner wall surface 39 is an inner wall surface of the terminal housing chamber 23 with which the substrate portion 15 comes into surface contact when the terminal 11 is inserted into the terminal housing chamber 23. Therefore, when the substrate portion 15 contacts the bottom wall surface of the terminal accommodating chamber 23, this bottom wall surface becomes the reference inner wall surface 39. Further, when the substrate portion 15 contacts the inner surface of the side wall of the terminal accommodating chamber 23, the inner surface of the side wall becomes the reference inner wall surface 39.

  A pair of parallel bent piece portions 17 are formed on the substrate portion 15 according to the present embodiment. The bent piece portion 17 is bent from the pair of edge portions along the terminal insertion direction (axis line 25) of the substrate portion 15 to the same direction side perpendicular to the substrate portion 15. That is, the cross-sectional shape orthogonal to the axis 25 of the board | substrate part 15 and a pair of bending piece part 17 becomes a U shape, as shown in FIG.2 (b). As shown in FIG. 3B, the bent piece portion 17 contacts a pair of adjacent inner wall surfaces 41 sandwiching the reference inner wall surface 39 of the terminal accommodating chamber 23. In addition, each bent piece portion 17 in contact with a pair of adjacent inner wall surfaces 41 abuts against an opposed inner wall surface 43 (see FIG. 7C) whose bent tip is parallel to the reference inner wall surface 39.

  In the terminal 11 of the present embodiment, a pair of electrical contact pieces 47 protrudes forward in the terminal insertion direction on each front end edge 45 of the pair of bent piece portions 17 on the front side in the terminal insertion direction into the terminal accommodating chamber 23. It is provided (extended). A V-shaped contact portion 49 bent in a direction approaching each other is formed on the distal end side of the pair of electrical contact pieces 47. Each electric contact piece 47 extended from the front end edge 45 of the bent piece portion 17 has a spring property so that the contact portions 49 can be elastically displaced in the approaching and separating directions.

  As shown in FIG. 1, the terminal 11 having the terminal structure according to the present embodiment has a height dimension of the bent piece portion 17 rather than the width dimension W1 of the substrate portion 15 in the direction orthogonal to the axis 25. H1 is formed small. Further, the width dimension W2 of the pair of electrical contact pieces 47 in the terminal 11 is formed to be smaller than the width dimension W1 of the substrate portion 15. Therefore, a gap 51 is secured between each electrical contact piece 47 and the adjacent inner wall surface 41 so that the electrical contact piece 47 can be elastically displaced outward (see FIG. 9). A mating electrical contact piece 55 of the mating terminal 53 (see FIG. 9) is inserted between the pair of electrical contact pieces 47. The pair of electrical contact pieces 47 is elastically displaced outward when the mating electrical contact piece 55 is inserted. At this time, each electric contact piece 47 comes into contact with the adjacent inner wall surface 41 when the electric contact piece 47 is deformed by a predetermined displacement or more. Thereby, the electrical contact piece 47 is suppressed from excessive deformation, and no permanent distortion remains.

  In addition, the terminal 11 provided with the terminal structure which concerns on this embodiment is demonstrated to the case where a pair of electric contact piece 47 is provided in the bending piece part 17 as a terminal connection part. A tab-like mating terminal 53 is inserted between the pair of electrical contact pieces 47. That is, the terminal 11 according to the present embodiment is a so-called female terminal. The terminal provided with the terminal structure according to the present invention may be a male terminal. In this case, instead of the pair of electrical contact pieces 47, tab terminals protruding forward from the board portion 15 are formed as terminal connection portions.

  Further, as shown in FIGS. 1 and 2A, the board portion 15 of the present embodiment is provided with a locking portion 19 upright on the front side in the terminal insertion direction. As shown in FIG. 4, the locking portion 19 is formed by forming a concave blank hole 57 in the substrate portion 15 and bending the inner convex piece 59 perpendicularly to the substrate portion 15. Accordingly, the locking portion 19 is perpendicular to both the substrate portion 15 and the bent piece portion 17. The locking portion 19 is locked by a locking lance 61 protruding from the opposing inner wall surface 43 of the connector housing 13 to the terminal accommodating space 21.

  The locking lance 61 of the present embodiment is formed in a cantilever shape in which the proximal end is connected to the opposed inner wall surface 43 of the terminal accommodating chamber 23 and the distal end protrudes in the insertion direction of the terminal 11. As shown in FIG. 3C, the locking lance 61 is formed to be inclined so as to gradually approach the reference inner wall surface 39 toward the tip. A locking step 63 is formed at the tip of the locking lance 61. When the terminal 11 is inserted into the terminal accommodating chamber 23 from the terminal insertion port 29, the locking lance 61 is pressed by the locking portion 19 of the terminal 11 and moved in a direction approaching the opposing inner wall surface 43. When the terminal 11 is further inserted into the terminal accommodating chamber 23 and the locking portion 19 advances, the locking step portion 63 gets over the locking portion 19 and the locking lance 61 is restored to its original position by elasticity. The locking step 63 locks the locking portion 19 from the rear side in the insertion direction. As a result, the terminal 11 is prevented from being removed from the terminal accommodating chamber 23.

  In the terminal accommodating chamber 23, a stopper portion 65 bulging inward is formed at the position of the reference inner wall surface 39 corresponding to the front end edge 46 of the substrate portion 15, as shown in FIG. . As shown in FIG. 7C, the terminal 11 is further prevented from being inserted when the front end edge 46 of the substrate portion 15 abuts against the stopper portion 65.

  Furthermore, the terminal 11 of the present embodiment includes a first conductor connecting piece 69 extending from the board portion 15 at the rear end of the board portion 15 on the side opposite to the protruding direction of the pair of electrical contact pieces 47, and a terminal insertion direction. A second conductor connection piece 71 parallel to the (axis line 25) and orthogonal to the first conductor connection piece 69 is connected. The first conductor connecting piece 69 and the second conductor connecting piece 71 as the conductor connecting portion are bent in an L shape. The inner surfaces of the first conductor connection piece 69 and the second conductor connection piece 71 are sufficient to electrically connect the conductor 75 of the electric wire 73 (see FIG. 5D) by soldering, heat welding, crimping, or the like. It has an area.

The terminal 11 having the terminal structure according to the present embodiment is mounted on the low-profile housing (connector housing) 79 in a posture (horizontal position) in which the board portion 15 is parallel to the horizontal plane, or the board portion 15 is perpendicular to the horizontal plane. It can be mounted on the narrow pitch housing (connector housing) 83 in such a posture (vertical placement).
As shown in FIGS. 5A to 5C, when the terminal 11 is inserted horizontally, a low profile connector 77 is used. The low profile connector 77 is a connector used when it is desired to keep the housing height dimension H of the low profile housing 79 low.
The terminal 11 applied to the low-profile connector 77 is a standard parallel to the arrangement direction of the plurality of terminal accommodating chambers 23 formed side by side in the low-profile housing 79 in the same direction in which the terminal insertion direction (axis 25) is parallel. The substrate portion 15 of the terminal 11 is in contact with the inner wall surface 39 (bottom wall surface) in a parallel state. Further, in this case, the conductor 75 of the electric wire 73 is soldered to the first conductor connecting piece 69 by solder 80 as shown in FIG.

On the other hand, as shown in FIGS. 6A to 6C, when the terminal 11 is inserted vertically, a narrow pitch connector 81 is used. The narrow pitch connector 81 is a connector used when it is desired to keep the housing width dimension W3 of the narrow pitch housing 83 small.
The terminal 11 applied to the narrow pitch connector 81 is a standard orthogonal to the direction in which the plurality of terminal accommodating chambers 23 formed in the narrow pitch housing 83 are aligned in the same direction in which the terminal insertion direction (axis 25) is parallel. The substrate portion 15 of the terminal 11 is in contact with the inner wall surface 39 (side wall inner surface) in a parallel state. In this case, the conductor 75 of the electric wire 73 is soldered to the second conductor connecting piece 71 by solder 80 as shown in FIG.

Next, the operation of the terminal structure having the above configuration will be described with reference to FIGS.
According to the terminal 11 having the terminal structure according to the present embodiment, the bent piece portions 17 are formed at the pair of edge portions of the substrate portion 15, respectively, and a cross-sectional shape orthogonal to the terminal insertion direction (axis line 25). However, it becomes U shape (refer FIG.2 (b)).

  As shown in FIG. 7, the board portion 15 of the terminal 11 inserted into the prismatic terminal accommodating space 21 in the terminal accommodating chamber 23 of the connector housing 13 is parallel to one reference inner wall surface 39 of the terminal accommodating chamber 23. Contact with. At this time, the pair of bent piece portions 17 formed by bending on the substrate portion 15 is in contact with a pair of adjacent inner wall surfaces 41 sandwiching the reference inner wall surface 39. The bent tip of the bent piece 17 abuts against the opposed inner wall surface 43 parallel to the reference inner wall surface 39. Therefore, the movement of the substrate portion 15 of the terminal 11 inserted into the rectangular columnar terminal accommodating space 21 having a quadrangular section is restricted between the reference inner wall surface 39 and the opposed inner wall surface 43 by the substrate portion 15 and the bent tip. The Further, the movement of the substrate portion 15 of the terminal 11 between the pair of adjacent inner wall surfaces 41 is restricted by the pair of bent piece portions 17. Thereby, the board | substrate part 15 of the terminal 11 is inserted in the terminal storage chamber 23 without shakiness in the direction which cross | intersects a terminal insertion direction (axis line 25).

Further, in the substrate portion 15 of the terminal 11 having a U-shaped cross section, a space defined by the substrate portion 15 and the pair of bent piece portions 17 becomes the terminal internal space 85. As shown in FIG. 8, when the terminal 11 is inserted into the terminal accommodating chamber 23, the terminal accommodating space 21 is inserted into the terminal accommodating space 85 from the opposing inner wall surface 43 (see FIG. 3C). A locking lance 61 that protrudes toward the front enters.
In the terminal 11 having the terminal structure of the present embodiment, the locking lance 61 projecting from the opposing inner wall surface 43 to the terminal accommodating space 21 in the terminal accommodating chamber 23 of the connector housing 13 is provided with the base plate portion 15 and a pair of bent portions. The locking portion 19 of the board portion 15 is locked by protruding into the terminal internal space 85 defined by the piece portion 17. Therefore, the installation space of the locking lance 61 protruding from the terminal accommodating space 21 of the terminal accommodating chamber 23 is absorbed by the terminal internal space 85 defined by the substrate portion 15 and the pair of bent piece portions 17. . Thereby, the connector housing 13 forming the terminal accommodating chamber 23 can be reduced in size by the installation space of the locking lance 61.

  Further, in the terminal 11 having the terminal structure according to the present embodiment, the electric contact piece 47 is connected to the front end edge 45 of each bent piece portion 17 formed by bending the pair of edge portions of the substrate portion 15. It protrudes and extends forward in the terminal insertion direction. The pair of electrical contact pieces 47 can be elastically displaced in the direction of approaching and separating from each other. Therefore, when the terminal 11 is coupled with the mating terminal 53, when the mating electrical contact piece 55 of the mating terminal 53 is inserted between the pair of electrical contact pieces 47, as shown in FIG. The mating electrical contact piece 55 inserted between the contact pieces 47 is elastically contacted with the electrical contact piece 47 from the front and back. That is, it makes elastic contact at two points on the front and back. Therefore, even if the counterpart electrical contact piece 55 is displaced in a direction approaching one of the pair of electrical contact pieces 47 due to vibration or the like, the other electrical contact piece 47 maintains a good contact state due to the elastic restoring force. Thereby, even when vibration is generated, the contact load of the pair of electrical contact pieces 47 is always secured at a predetermined value, and instantaneous interruption can be suppressed.

Further, when the pair of electrical contact pieces 47 is likely to be deformed (expanded) beyond the design value due to the fitting angle of the counterpart electrical contact piece 55 and the like, the pair of adjacent inner wall surfaces 41 of the terminal accommodating chamber 23. Therefore, excessive deformation is suppressed. Thereby, the excessive displacement and opening of the electrical contact piece 47 are suppressed.
Therefore, the electrical contact reliability of the pair of electrical contact pieces 47 with respect to the counterpart electrical contact piece 55 is not impaired.

  Moreover, in the terminal 11 provided with the terminal structure according to the present embodiment, the first conductor connecting piece 69 extending from the board portion 15 is parallel to the terminal insertion direction (axis 25) at the rear end portion of the terminal 11 and A second conductor connection piece 71 orthogonal to the first conductor connection piece 69 is connected (see FIG. 1). Even when the board portion 15 of the terminal 11 is rotated at a rotation angle of 90 ° about the axis 25, either the first conductor connecting piece 69 or the second conductor connecting piece 71 is connected to the conductor connecting portion. It becomes possible to arrange | position to the conductor 75 of the electric wire 73 in the same position.

  Accordingly, as shown in FIG. 5 and FIG. 6, the terminal accommodation is performed depending on the configuration of the low-profile housing 79 and the narrow-pitch housing 83 to which the terminal 11 is assembled, the size restrictions of the low-profile connector 77, the narrow-pitch connector 81, and the like. Even if the direction of the board portion 15 inserted into the chamber 23 is changed, the first conductor connection piece 69 or the second conductor connection piece 71 is electrically connected to the conductor 75 of the electric wire 73 by soldering under the same conditions. Connection can be made.

  Further, according to the low-profile connector 77 according to the present embodiment, the terminal 11 is higher in the bent piece portion 17 than the width dimension W1 of the substrate portion 15 in the direction orthogonal to the terminal insertion direction (axis line 25). The dimension H1 is formed small. And as shown in FIG. 5, each terminal 11 is each terminal so that each board | substrate part 15 may contact | connect with each reference | standard inner wall surface 39 parallel to the arrangement direction of the some terminal storage chamber 23 in a parallel state. The housing height dimension H1 of the low-profile housing 79 in the direction orthogonal to the arrangement direction of the plurality of terminal accommodating chambers 23 can be reduced by being inserted horizontally in the accommodating chamber 23.

  Further, according to the narrow pitch connector 81 according to the present embodiment, as shown in FIG. 6, each substrate portion 15 is parallel to each reference inner wall surface 39 orthogonal to the arrangement direction of the plurality of terminal accommodating chambers 23. Each terminal 11 is inserted vertically in each terminal accommodating chamber 23 so as to come into contact with each other, thereby reducing the housing width dimension W3 of the narrow pitch housing 83 in the arrangement direction of the plurality of terminal accommodating chambers 23. it can.

  Therefore, according to the terminal structure and connector 35, the low profile connector 77, and the narrow pitch connector 81 according to the present embodiment, the connector can be miniaturized.
