Description

  The present invention relates to a female terminal, and more particularly to a female terminal into which a flat tab of a male terminal is inserted / removed.

  Conventionally, as a female terminal used for an electrical system such as an automobile, for example, as described in JP-A-8-31490 (Patent Document 1), a box-shaped main body having an opening at the front end, and a main body What is provided with the elastic contact piece which can bend-deformed and protrudes toward the inside of a part is known. Such a female terminal is accommodated and disposed in the housing hole of the connector housing, and the contact provided on the elastic contact piece is brought into elastic contact with the flat tab of the male terminal inserted from the opening, whereby the male terminal The electrical connection with can be achieved.

  By the way, in the female terminal of such a conventional structure, as shown in FIG. 2 of Patent Document 1, a flat tab of the male terminal inserted into the main body portion of the female terminal and the left and right side walls of the main body portion. It was inevitable that a large gap was formed between them. Therefore, due to vibration of the vehicle body and the like, the flat tab tends to rattle within the main body so that the head swings in the plate width direction, and there is a possibility that stable contact of the contact of the elastic contact piece with the flat tab may not be achieved. It was.

  In view of this, Japanese Patent Laid-Open No. 2001-210418 (Patent Document 2) discloses an emboss projectingly provided on the inner surfaces of the left and right opposing side walls that constitute the main body, so A structure for reducing the gap between the two has been proposed. According to this, even when the vibration of the vehicle body occurs, the lateral displacement of the flat tab can be effectively regulated by the contact between the flat tab and the emboss. Stable contact of the tabs can be ensured.

  However, in the female terminal of Patent Document 2, the gap between the side wall of the main body part of the female terminal and the flat tab of the male terminal is reduced by the pair of embossments projecting from the side wall of the main body part. There was a problem of increasing the insertion force of the tab of the terminal. In addition, the female terminals and male terminals, which are press-processed products, have large product variations in terms of dimensions. Therefore, in the structure of the female terminal of Patent Document 2 in which the allowable dimensional tolerance is small, there is a possibility that the productivity is deteriorated.

JP-A-8-31490 Japanese Patent Laid-Open No. 2001-210418

  The present invention has been made in the background of the above-described circumstances, and the problem to be solved is that the plate-like tab of the male terminal is effectively restricted from swinging the plate-like tab of the male terminal in the plate width direction. An object of the present invention is to provide a female terminal having a novel structure that can advantageously reduce insertion force and absorb dimensional variations between products.

  Hereinafter, embodiments of the present invention made to solve the above-described problems will be described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  A first aspect of the present invention includes a box-shaped main body having an opening at a front end, and a flexible deformable elastic contact piece protruding toward the inside of the main body, from the opening of the main body In the female terminal in which the contact point of the elastic contact piece that is bent and deformed is elastically contacted with the flat tab of the male terminal to be inserted, the main body facing the plate width direction of the flat tab On the pair of side walls, a pair of elastic support pieces projecting in a cantilever manner toward the inside of the main body is provided, while the protruding end portions of the pair of elastic support pieces are constrained by other members. In such a state, the pressure contact portions of the elastic support pieces are brought into pressure contact with both side surfaces in the plate width direction of the flat tab inserted through the opening.

  According to this aspect, the protruding end portions of the pair of elastic support pieces are configured to elastically support the flat tab of the male terminal from both sides in the plate width direction in a free state where the protruding end portions are not restrained by other members. Therefore, the flat tab of the male terminal can be stably held at a desired position of the main body by the elastic force of the pair of elastic support pieces. Even if the plate-like tab is displaced in the plate width direction due to vibration of the vehicle body or the like, the plate-like tab is quickly guided to a predetermined position by the elastic force of the elastic support pieces pressed against both sides of the plate-like tab, Excessive displacement can be prevented and further contact stabilization can be achieved. Further, since the elastic support piece can follow the displacement of the flat tab, the interference between the flat tab and the elastic support piece can be advantageously prevented, and the male terminal is protected while the male terminal is protected. Therefore, the positioning can be performed stably.

  Moreover, since the pair of elastic support pieces are pressed from both sides of the plate-like tab in the plate width direction, the male terminal is compared with the case where the male terminal is inserted between the pair of embossments as in the prior art. The insertion force can be reliably reduced. Further, since the elastic support pieces arranged on both sides of the flat tab can be elastically deformed, the dimensional variation of the female terminal and the male terminal can be advantageously absorbed. Therefore, a large allowable dimensional tolerance of the female terminal and the male terminal can be secured, and the productivity can be improved.

  According to a second aspect of the present invention, in the female terminal according to the first aspect, a plurality of the elastic contact pieces are provided apart from each other in the plate width direction of the flat tab, while the plate of the flat tab is provided. Each of the pair of wall portions facing in the thickness direction is folded inward from the front ends of each of the wall portions so as to be able to bend and deform in the facing direction of the wall portions, and provided at the distal end portion in the extending direction of the elastic contact piece. The contacts are press-contacted from both sides in the plate thickness direction of the flat tab so that they can be independently displaced.

  According to this aspect, a plurality of elastic contact pieces are provided apart from each other in the plate width direction of the flat tab and are pressed from both sides in the plate thickness direction of the flat tab. The contact of the elastic contact piece can be brought into contact with a plurality of locations on the tab. As a result, even when vibration of the vehicle body occurs, the contact stability of the female terminal with respect to the male terminal is advantageously ensured by following the deflection in the plate thickness direction and displacement in the twisting direction advantageously. In addition, the sliding of the contacts can be prevented.

  Further, the flat tab is attached to the female terminal main body by the press contact of the plurality of elastic contact pieces from both sides of the flat tab and the pair of elastic support pieces from both sides of the flat tab. Positioning can be performed more stably at a predetermined position.

  According to a third aspect of the present invention, in the female terminal according to the first or second aspect, in the insertion direction of the tabular tab into the main body, the contact from the opening of the main body to the contact. The separation distance is at least 1.2 times the separation distance of the press contact portion from the opening of the main body portion.

  According to this aspect, in the insertion direction of the flat tab, the separation distance from the opening is ensured to be as large as 1.2 times or more the pressure contact portion of the elastic support piece at the contact point of the elastic contact piece. As a result, a large moment with a pressure contact part as a fulcrum and a contact point as a point of action, that is, a large deterrence against the above vibration, acts on the vibration force in the plate width direction generated by the vibration of the vehicle body on the flat tab. Can be more effectively regulated. In short, it is desirable that the separation distance from the opening of the contact point of the elastic contact piece is larger, more preferably 1.4 times or more, more preferably 1.5 times the separation distance from the opening of the pressure contact portion of the elastic support piece. More than double. In addition, since the time when the contact point of the elastic contact piece and the pressure contact portion of the elastic support piece abut on the flat tab inserted from the opening is shifted, the insertion force of the flat tab is reduced. .

  Moreover, since the positions of the contact points of the elastic contact pieces and the pressure contact portions of the elastic support pieces are shifted in the insertion direction of the flat plate tabs, both of them can be displaced independently of each other. Each elastic contact piece and each elastic support piece can flexibly follow the displacement in the vertical direction and the horizontal direction (the prying direction). Thereby, the contact stability to the flat tab of the contact part of an elastic contact piece and the press-contact part of an elastic support piece can be improved reliably.

  According to the female terminal of the present invention, the protruding end portions of the pair of elastic support pieces are configured to elastically support the flat tabs of the male terminal from both sides in the plate width direction in a free state where they are not restrained by other members. ing. Therefore, the flat tab can be stably held at a desired position of the main body by the elastic force of the pair of elastic support pieces. Further, since the elastic support pieces arranged on both sides of the flat tab can be elastically deformed, the dimensional variation of the female terminal and the male terminal can be advantageously absorbed. Therefore, a large allowable dimensional tolerance of the female terminal and the male terminal can be secured, and the productivity can be improved.

The expanded view of the female terminal shown in FIG. It is a figure explaining the state at the time of male terminal insertion completion to the female terminal of this embodiment, Comprising: Sectional drawing corresponded in FIG. VIII-VIII sectional drawing in FIG.

  Embodiments of the present invention will be described below with reference to the drawings.

  First, the female terminal 10 as one Embodiment of this invention is shown by FIGS. The female terminal 10 includes a box-shaped main body portion 14 having an opening 12 at a front end, and a barrel portion 16 having a core wire crimping portion 52 that is caulked and fixed to a core wire 58 of a covered electric wire 54 described later. It is comprised integrally with. In addition, a flat tab 20 of the male terminal 18 can be inserted into the opening 12 of the main body 14 from the front, whereby an electrical connection between the female terminal 10 and the male terminal 18 can be achieved. ing. In the following description, “upper” means the upper side in FIG. 1, and “lower” means the lower side in FIG.

  More specifically, the female terminal 10 is formed using various metal materials that have conductivity and can be pressed or punched, such as brass, copper, copper alloy, aluminum, aluminum alloy, and the like. Has been. In the present embodiment, the thickness dimension of the female terminal 10 is substantially constant throughout.

  The main body portion 14 is formed in a substantially box shape, and includes a pair of wall portions 22a and 22b facing each other in the vertical direction and another pair of side walls 24a and 24b facing each other in the left-right direction. Yes.

  Flat plate portions 28 and 28 are provided at the front ends of the pair of wall portions 22a and 22b opposite to each other in the vertical direction, which is the plate thickness direction of the flat tab 20 (see FIG. 6). As shown in FIG. 3, the body part 14 is folded back from the front end. As shown in FIG. 5, each flat plate portion 28 is divided into two elastic contact pieces 28 a and 28 b through a notch 32 at a portion protruding inward from the folded portion 30 to the main body 14. As a result, the elastic contact pieces 28a and 28b extend in a cantilevered manner from the folded-back portion 30 serving as the base end portion to the inside of the main body portion 14 while being separated in the left-right direction, which is the plate width direction of the flat tab 20. Thus, a plurality of configurations are provided. Further, the elastic contact pieces 28a and 28b extend from the folded portion 30 toward the inside of the main body portion 14 and extend while inclining toward the center of the main body portion 14 in the vertical direction (vertical direction in FIG. 4). The front end portion in the extending direction is bent to be inclined outward in the vertical direction (vertical direction in FIG. 4) of the main body 14. As a result, the portions of the elastic contact pieces 28a, 28b that protrude most to the center in the vertical direction of the main body portion 14 are contact points 34a, 34b that contact the flat tab 20. In the present embodiment, the contacts 34a and 34b are formed so as to project in a dome shape toward the central side of the main body 14 in the vertical direction (vertical direction in FIG. 4).

  In this way, the elastic contact pieces 28a and 28b that protrude toward the inside of the main body 14 and face each other in the facing direction of the walls 22a and 22b (the vertical direction in FIG. 4) can be bent and deformed so as to be separated from each other. It is said that. Then, the contacts 34a and 34b of the elastic contact pieces 28a and 28b deformed and deformed so as to be elastically contacted with the flat tab 20 of the male terminal 18 inserted from the opening 12 of the main body portion 14. It has become. In addition, as shown in FIG. 4, the opening part 12 of the main-body part 14 is comprised by the clearance gap between the folding | returning parts 30 and 30 of the flat plate parts 28 and 28 used as the base end part side of the elastic contact pieces 28a and 28b. . Further, the separation distance between the contact points 34 a and 34 b of the elastic contact pieces 28 a and 28 b facing vertically is set smaller than the plate thickness dimension of the flat tab 20 of the male terminal 18.

  In addition, a pair of embossings 36, 36 are trapezoidal toward the inside of the main body 14 at the rear end portions of the pair of wall portions 22 a, 22 b opposite to each other in the vertical direction that is the plate thickness direction of the flat tab 20. It is formed to protrude in a cross-sectional shape.

  On the other hand, in the pair of side walls 24 a and 24 b of the main body 14 facing each other in the left-right direction that is the plate width direction of the flat tab 20, the pair of elastic support pieces 38 and 38 are cut toward the inside of the main body 14, respectively. It is raised and formed in a cantilevered manner. More specifically, the pair of elastic support pieces 38 and 38 protrude from the rear end portions of the pair of side walls 24a and 24b so as to incline toward the center side of the main body portion 14 in the left-right direction (vertical direction in FIG. 5). The tip end portion in the protruding direction is bent so as to be inclined outward in the left-right direction (vertical direction in FIG. 5) of the main body 14. As a result, the portion of the elastic support piece 38 that protrudes most to the center in the left-right direction of the main body portion 14 serves as a press-contact portion 40 that press-contacts the flat tab 20.

  Thus, the elastic support pieces 38 that protrude toward the inside of the main body 14 and face each other in the opposing direction of the side walls 24a and 24b (vertical direction in FIG. 5) can be bent and deformed so as to be separated from each other. Yes. And the protrusion edge part of a pair of elastic support pieces 38 and 38 is not restrained by another member with respect to the plate width direction both sides of the flat tab 20 of the male terminal 18 inserted from the opening part 12 of the main-body part 14. In this state, the pressure contact portion 40 of the elastic support piece 38 that has been bent and deformed and its peripheral region are pressure contacted.

  By the way, the female terminal 10 having such a structure can be manufactured by the following method. For example, a metal flat plate is stamped into a developed shape as shown in FIG. In the developed shape shown in FIG. 6, the base end portions of the flat plate portions 28, 28 provided extending from the front ends (left side in FIG. 6) of the pair of wall portions 22 a, 22 b are the formation portions of the folded portions 30. Further, a portion extending further forward is divided into two elastic contact pieces 28 a and 28 b via the notch 32. Then, the entire flat plate portions 28, 28 are folded back in a mountain shape from the folded portion 30 toward the wall portions 22a, 22b, and the elastic contact pieces 28a, 28b are bent in the opposite direction in the extending direction so that appropriate elasticity is obtained. Contact points 34a and 34b to which force is applied are formed. In addition, the folding | returning part 30 which gives elastic force to each elastic contact piece 28a, 28b is comprised by the same flat plate part 28, and the base end part of each elastic contact piece 28a, 28b mutually mutually via the folding | returning part 30 Since they are integrally connected, the rigidity and durability of each elastic contact piece 28a, 28b is ensured.

  Next, the elastic support piece 38 formed by cutting out the central part of the pair of side walls 24a, 24b in a U-shape is raised, while the tip end portion of the cut elastic support piece 38 is bent in the opposite direction. By doing so, the press-contact part 40 to which appropriate elastic force was provided is formed.

  Then, both side walls 24a, 24b are bent from the wall portion 22b that hits the bottom plate so as to face each other, and the wall portion 22a that hits the continuous ceiling plate from the side wall 24a is bent so as to face the wall portion 22b. The opened box-shaped main body 14 is assembled.

  As shown in FIG. 6, an engagement hole 44 is provided in the side edge portion 42 of the side wall 24 b, and the side edge portion 46 of the one wall portion 22 a is engaged with the engagement hole 44. A stop 48 is projected. After the engaging portion 48 is fitted into the engaging hole 44, the side edge portion 42 of the side wall 24b is bent until it abuts against the wall portion 22a, whereby the side wall 24b and the wall portion 22a are engaged and fixed. In this state, the elastic contact pieces 28a and 28b folded inward from the front ends of the pair of wall portions 22a and 22b of the main body portion 14 are opposed to each other with a gap therebetween, and the pair of wall portions 22a and 22b. The elastic contact pieces are formed so as to be able to bend and deform independently of each other in the opposing direction. Further, the contact points 34a and 34b provided at the leading end portions in the extending direction of the elastic contact pieces 28a and 28b and protruding most to the center side of the main body 14 are press-contacted from both sides in the plate thickness direction of the flat tab 20 so as to be independently displaceable. It has come to be. The elastic contact pieces 28 a and 28 b are symmetrical on both sides in the vertical direction, which is the thickness direction of the flat tab 20. In addition, an emboss 36 is provided between the front ends of the elastic contact pieces 28a and 28b in the extending direction and the wall portions 22a and 22b.

  Similarly, in this state, the elastic support pieces 38 cut and raised inwardly from the pair of side walls 24a and 24b of the main body 14 are disposed to face each other with a gap therebetween, and the facing direction of the pair of side walls 24a and 24b. The elastic support pieces 38 are formed so as to be able to bend and deform independently of each other. Further, the pressure contact portion 40 provided at the front end portion in the protruding direction of the elastic support piece 38 and protruding most to the center side of the main body portion 14 is pressed from both sides in the plate width direction of the flat tab 20 so as to be independently displaceable. It has become. The elastic support piece 38 has a symmetrical shape on both sides in the left-right direction, which is the plate width direction of the flat tab 20.

  Furthermore, a barrel portion 16 in a developed state, that is, a flat plate is provided behind the wall portion 22b that hits the bottom plate, and a plurality of ridges 50, 50 extending in parallel with each other protrude upward. A pair of core wire crimping portions 52 and 52 are formed by bending both side portions in the width direction of the barrel portion 16 on the flat plate upward.

  The covered electric wire 54 is crimped to the rear end side of the female terminal 10 of this embodiment having such a structure. In order to crimp the coated electric wire 54, the insulating coating 56 on the distal end side of the coated electric wire 54 is peeled to expose the core wire 58, and the distal end portion of the coated electric wire 54 where the core wire 58 is exposed is used as the barrel portion 16 of the female terminal 10. Is placed on the upper surface of the protrusion 50. Under such a state, the barrel part 16 provided with the core wire crimping parts 52 and 52 is plastically deformed by performing crimping processing on the core wire crimping parts 52 and 52 using a known crimping device, and the core wire It is crimped so that 58 is wrapped from the outer peripheral surface.

  Then, the female terminal 10 to which the covered electric wire 54 is crimped is accommodated in the terminal accommodating hole 62 of the connector housing 60 as shown in FIG. An opening window 64 communicating with the terminal receiving hole 62 is formed at the end of the connector housing 60, and the opening 12 of the female terminal 10 is exposed to the outside through the opening window 64 so that the male terminal 18 can be connected. It is said that.

  As shown in FIGS. 7 and 8, the flat tab 20 of the male terminal 18 includes elastic contact pieces 28 a and 28 b provided on the upper and lower walls 22 a and 22 b from the opening 12 on the front surface of the main body 14. The elastic support pieces 38 provided on the left and right side walls 24a and 24b are inserted while being bent and deformed. The flat tab 20 is first elastically sandwiched between the press contact portions 40 of the pair of elastic support pieces 38 that are press-contacted at the intermediate portion of the main body portion 14 to be connected. Next, when the flat tab 20 is further inserted, in addition to the connection with the pressure contact portion 40, the contacts 34a, 28a, 28b of the pair of elastic contact pieces 28a, 28b press-contacted on both sides of the flat tab 20 in the plate thickness direction. 34b is elastically sandwiched between the two to be connected. Even when the female terminal 10 and the male terminal 18 are connected to each other, the protruding end portions of the pair of elastic support pieces 38 and 38 are not restrained by other members such as the connector housing 60 (FIG. 8). Further, by providing the emboss 36, excessive displacement of the elastic contact pieces 28a and 28b due to the vibration of the flat tab 20 in the thickness direction is advantageously prevented.

  As shown in FIG. 8, in the insertion direction of the flat tab 20 into the main body 14, the separation distance L2 from the opening 12 of the main body 14 to the contacts 34a, 34b of the elastic contact pieces 28a, 28b is the main body. The separation distance of the pressure contact portion 40 from the 14 opening portions 12 is set to 1.2 times or more of L1. As a result, a large moment with the pressure contact portion 40 as a fulcrum and the contact points 34a and 34b as action points, that is, a large deterrence against the above-described deflection, acts on the deflection force in the plate width direction generated in the flat tab 20 due to vibrations of the vehicle body. For this reason, it is possible to more effectively regulate the shake. In short, it is desirable that the distance L2 from the opening 12 of the contact 34a, 34b of the elastic contact piece 28a, 28b is larger, and more preferably, the distance from the opening 12 of the pressure contact part 40 of the elastic support piece 38: L1 is 1.4 times or more, more preferably 1.5 times or more. In addition, since the timing when the pressure contact portion 40 of the elastic support piece 38 and the contacts 34a and 34b of the elastic contact pieces 28a and 28b abut on the flat tab 20 inserted from the opening 12 is shifted, the flat tab The insertion force of 20 can be distributed, and the insertion force of the flat tab 20 is increased step by step, thereby reducing the insertion force felt by the operator and realizing smooth mounting.

  In addition, the positions of the contact points 34a, 34b of the elastic contact pieces 28a, 28b and the pressure contact portion 40 of the elastic support piece 38 are shifted in the insertion direction of the flat tab 20, and both of them can be displaced independently of each other. Therefore, the elastic contact pieces 28a and 28b and the elastic support pieces 38 can flexibly follow the displacement of the flat tab 20 in the vertical direction and the horizontal direction (pegging direction). Thereby, the contact stability to the flat tab 20 of the contact part 34a, 34b of the elastic contact pieces 28a and 28b and the press-contact part 40 of the elastic support piece 38 can be improved reliably.

  According to the female terminal 10 of this embodiment, the flat tab 20 of the male terminal 18 can be moved in a free state where the press contact portions 40, 40 of the pair of elastic support pieces 38, 38 are not restrained by other members. The structure is elastically supported from both sides in the plate width direction. Thereby, the flat tab 20 of the male terminal 18 can be stably held at a desired position in the main body 14. Further, even if the flat tab 20 is displaced in the plate width direction due to vibration of the vehicle body or the like, the flat tab 20 is quickly guided to a predetermined position by the elastic force of the elastic support piece 38 to prevent excessive displacement. In addition, further contact stabilization can be achieved. In addition, since the elastic support piece 38 can follow the displacement of the flat tab 20, interference between the flat tab 20 and the elastic support piece 38 can be advantageously prevented. Therefore, it is possible to stably position the female terminal 10 in the main body 14 while protecting the male terminal 18.

  In addition, the insertion force of the male terminal 18 can be reliably reduced as compared with the case where the male terminal 18 is inserted between a pair of embossments as in the prior art. Further, since the elastic support pieces 38 disposed on both sides of the flat tab 20 of the male terminal 18 can be elastically deformed, the dimensional variation of the female terminal 10 and the male terminal 18 can be advantageously absorbed. Therefore, a large allowable dimensional tolerance of the female terminal 10 and the male terminal 18 can be ensured, and the productivity can be improved.

  A plurality of elastic contact pieces 28 a and 28 b are provided apart from each other in the plate width direction of the flat tab 20, and are pressed from both sides of the flat tab 20 in the plate thickness direction. Thus, even when vibration of the vehicle body occurs, the contact stability of the male terminal 18 with respect to the female terminal 10 is advantageously followed by following the deflection in the plate thickness direction and the displacement in the twisting direction advantageously. It can be ensured and sliding of the contacts 34a and 34b can be prevented.

  Further, the plate-like tab 20 is pressed by a plurality of elastic contact pieces 28a, 28b from both sides in the plate thickness direction and the plate-like tab 20 is pressed by a pair of elastic support pieces 38, 38 from both sides in the plate width direction. The tab 20 can be positioned more stably at a predetermined position of the main body portion 14 of the female terminal 10.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited at all by the specific description in this embodiment. For example, in the illustrated embodiment, two elastic contact pieces 28a and 28b are provided. However, the present invention is not limited to this, and three or more elastic contact pieces 28a and 28b may be provided. The shape of the elastic contact piece, the number of contacts, and the like can be appropriately set according to the required pressure contact force.
