[0011] (1) The gripping portion of the terminal fitting is separate from the displacement-allowing portion and can be gripped from behind, so that the terminal fitting can be easily accommodated in the cavity of the housing while gripping the gripping portion.

[0012] (2) The terminal fitting according to (1), wherein the gripping portion extends rearward in a cantilevered manner.

[0013] (2) The terminal fitting allows the rear edge of the gripping portion to be pressed from behind, so when inserting the terminal connection portion into the cavity of the housing, it is possible to insert it by pressing the gripping portion from behind.

[0014] (3) The terminal connection portion has a rigid portion extending rearward in an L-shape and connected to rear ends of the first wall portion and the second wall portion adjacent to each other, The terminal fitting according to (2), wherein the gripping portion is provided so as to be continuous with a rear end of the rigid portion.

[0015] (3) The terminal fitting has an L-shaped rigid portion that prevents relative displacement between the gripping portion and the terminal connection portion.

[0019] (5) When viewed from the front or rear, the terminal fitting can be arranged so that the rigid portion and the first elastic portion do not protrude from the terminal connection portion, making it easy to reduce the external dimensions of the terminal fitting.

[0020] (6) A terminal fitting according to any one of (1) to (5), an inner housing having a plurality of cavities for accommodating the terminal connection portions; an outer housing to which the board connection portion is connected; A connector comprising:

[0021] In the connector of (6), the terminal connecting portion can be inserted into the cavity of the inner housing while holding the grip portion, so that the terminal fittings are easy to handle and assemble.

[0022] [Details of the embodiments of the present disclosure] <Embodiment 1> The connector 100 of the first embodiment is attached to one mounting surface of a circuit board S and mates with a mating connector P (see FIG. 8) attached to the mounting surface of a circuit board (not shown) provided separately from the circuit board S. As shown in FIG. 1, the connector 100 includes a plurality of terminal fittings 11, an inner housing 91, an outer housing 92, and a pair of pegs 93. The terminal fittings 11 and the pegs 93 are formed by pressing a conductive metal plate. The inner housing 91 and the outer housing 92 are made of synthetic resin. In the drawings of the first embodiment, the "front side," "rear side," "upper side," "lower side," "right side," and "left side" are represented by "F," "B," "U," "D," "R," and "L," respectively. The front-to-rear direction is the direction in which the connector 100 mates with the mating connector P.

[0023] [Terminal metal fitting configuration] The multiple terminal fittings 11 have the same shape. As shown in FIGS. 2 and 3, each terminal fitting 11 includes a terminal connection portion 11A, a rigid portion 11B extending rearward in an L-shape from the rear end of the terminal connection portion 11A, a grip portion 11C connected to the rear end of the rigid portion 11B, a displacement-permitting portion 11D, and a board connection portion 11E. The terminal connection portion 11A has a rectangular cylindrical shape that extends in the front-rear direction and is open on both sides in the front-rear direction. The terminal connection portion 11A has a rectangular cylindrical shape formed by a first wall portion 11F, a second wall portion 11G, a third wall portion 11H, and a fourth wall portion 11J. The first wall portion 11F is located on the lower side. The second wall portion 11G is located on the left side, and its lower edge is connected to the first wall portion 11F (see FIG. 3). The third wall 11H is disposed on the upper side, and its left edge is continuous with the second wall 11G. The fourth wall 11J is disposed on the right side, and its upper edge is continuous with the third wall 11H and its lower edge is continuous with the first wall 11F (see FIG. 2). The third wall 11H is provided with a locking portion 11S that protrudes upward.

[0024] A resilient contact piece 11T is provided inside the terminal connection part 11A (see FIG. 4). The resilient contact piece 11T is connected to a mating terminal T (tab) (see FIG. 8). The tab is inserted into the terminal connection part 11A from the front, comes into contact with the resilient contact piece 11T, and is connected to the terminal connection part 11A.

[0025] Rigid portion 11B is formed to extend rearward in an L-shape flush with first wall portion 11F and second wall portion 11G of the walls forming terminal connection portion 11A (see FIG. 3). Specifically, rigid portion 11B has a first rigid portion 11U flush with first wall portion 11F with its thickness oriented in the up-down direction, and a second rigid portion 11V flush with second wall portion 11G with its thickness oriented in the left-right direction. The long sides of first rigid portion 11U and second rigid portion 11V are joined to form an L-shape. This makes rigid portion 11B less likely to deform and allows it to maintain its shape.

[0026] The grip portion 11C is provided so as to be continuous with the rear end of the first rigid portion 11U of the rigid portion 11B and extend rearward. In other words, the grip portion 11C is provided rearward of the terminal connection portion 11A. The grip portion 11C is arranged so as to be flush with the first rigid portion 11U of the rigid portion 11B and the first wall portion 11F of the terminal connection portion 11A (see FIG. 3). The grip portion 11C extends rearward in a cantilevered manner. In other words, there is nothing arranged behind the grip portion 11C. Therefore, the grip portion 11C is a portion that can be gripped from behind.

[0027] The displacement-permitting portion 11D includes a first elastic portion 11K and a second elastic portion 11L that extend in the front-rear direction and are elastically deformable. The displacement-permitting portion 11D and the grip portion 11C are separate portions. The first elastic portion 11K and the second elastic portion 11L are strip-shaped. The first elastic portion 11K and the second elastic portion 11L overlap with the rigid portion 11B in the front-rear direction. Specifically, the first elastic portion 11K is arranged behind the fourth wall portion 11J so as to be spaced apart (see FIG. 2). The thickness direction of the first elastic portion 11K is oriented in the left-right direction. The second elastic portion 11L is arranged behind the third wall portion 11H so as to be spaced apart (see FIG. 2). The thickness direction of the second elastic portion 11L is oriented in the up-down direction. That is, the first elastic portion 11K is elastically deformable in its thickness direction (left-right direction) but not in a direction perpendicular to the thickness direction (up-down direction). The second elastic portion is elastically deformable in its thickness direction (up-down direction) but not in a direction perpendicular to the thickness direction (left-right direction).

[0028] The rear end of the first elastic portion 11K is connected to the rear end of the rigid portion 11B, which is connected to the first wall portion 11F, so that the thickness direction of the first elastic portion 11K is perpendicular to the thickness direction of the rigid portion 11B. The front ends of the first elastic portion 11K and the second elastic portion 11L are connected to each other at a right angle. The front ends of the first elastic portion 11K and the second elastic portion 11L are connected to each other further forward than the rear ends of the first elastic portion 11K and the second elastic portion 11L. The second elastic portion 11L is inclined upward (away from the rigid portion 11B) toward the rear end.

[0029] The board connecting portion 11E includes a press-fit portion 11M and a connection main body portion 11N. The press-fit portion 11M is strip-shaped and extends in the front-rear direction with the plate thickness direction facing up and down. A plurality of press-fit blades 11P protruding in the left and right directions are provided on both left and right edge portions of the press-fit portion 11M. A pair of rectangular portions 11Q protruding in the left and right directions are provided on the rear end portion of the press-fit portion 11M. The connection main body portion 11N is connected to the rear end of the board connecting portion 11E and extends while bending upward.

[0030] The front end of the press-fit portion 11M is connected to the rear end of the second elastic portion 11L of the displacement-permitting portion 11D via the connecting plate portion 11R. In other words, the rear end of the second elastic portion 11L is connected to the press-fit portion 11M of the board connection portion 11E via the connecting plate portion 11R. That is, the rear end of the second elastic portion 11L is electrically connected to the board connection portion 11E side. In other words, the displacement-permitting portion 11D is provided between the terminal connection portion 11A and the board connection portion 11E. The connecting plate portion 11R extends vertically with its plate thickness oriented in the front-rear direction. In a front view from the front, the rigid portion 11B and the first elastic portion 11K are arranged within the range of the outline of the external shape of the terminal connection portion 11A (see FIG. 4). In this way, the terminal fitting 11 is formed.

[0031] As shown in Fig. 5, when the terminal fitting 11 is unfolded (left side in Fig. 5), the rigid portion 11B, the first elastic portion 11K, and the second elastic portion 11L are connected so as to be folded back in the front-rear direction. After the bending process is completed (right side in Fig. 5), the terminal fitting 11 is transported with the gripping portion 11C connected to the carrier Ca. Specifically, the terminal fitting 11 is bent so that the gripping portion 11C is perpendicular to the carrier Ca, and the terminal fitting 11 is oriented so that the rigid portion 11B and the board connecting portion 11E are aligned in the direction in which the plate surface of the carrier Ca extends.

[0032] [Inner housing configuration] As shown in Fig. 6, the inner housing 91 has a block-shaped housing main body 91A, a partition wall 91B extending downward from the housing main body 91A, and a pair of extension portions 91C extending outward in the left-right direction from the lower end of the partition wall 91B. A plurality of cavities 91D are formed in the housing main body 91A, penetrating the housing main body 91A in the front-rear direction. The plurality of cavities 91D are aligned in the left-right direction and are formed in two upper and lower rows. Each cavity 91D is provided with a lance 91E (see Fig. 9).

[0033] The partition wall 91B is provided so as to protrude downward from the housing main body 91A with its plate thickness oriented in the vertical direction. The partition wall 91B is continuous with the lower ends of the wall portion that separates the cavities 91D arranged in two rows, one above the other (see FIG. 9). At both left and right ends of the partition wall 91B, left and right partition walls 91G are provided so as to extend downward from both left and right ends of the housing main body 91A with their plate thickness oriented in the horizontal direction.

[0034] The pair of extensions 91C extend outward in the left-right direction from the left-right partition wall 91G of the partition wall 91B. A convex portion 91F protruding in the up-down direction is provided at the left-right protruding end of each extension 91C. In this manner, the inner housing 91 is formed.

[0035] [Outer housing configuration] As shown in Fig. 7, the outer housing 92 has a rectangular ring shape. The outer housing 92 has a pair of upper and lower holding wall portions 92A extending in the left-right direction, and a pair of left and right cover portions 92B arranged on both left and right sides and connecting the pair of upper and lower holding wall portions 92A. A plurality of groove portions 92C are formed in the pair of upper and lower holding wall portions 92A and aligned in the left-right direction. Each groove portion 92C is open inward in the up-down direction and rearward.

[0036] The pair of left and right cover portions 92B define an accommodation space C therein. The accommodation space C is open inward in the left-right direction and downward. An attachment recess 92D recessed inward in the left-right direction is formed at the outer left-right end of each cover portion 92B. The outer housing 92 has an opening 92E surrounded by a pair of upper and lower holding wall portions 92A and a pair of left and right cover portions 92B. The outer housing 92 is formed in this manner.

[0037] [Peg Configuration] 1, a pair of pegs 93 are arranged with their plate thicknesses facing the left-right direction. The lower end of each peg 93 is folded back outward in the left-right direction. A plurality of locking projections 93A projecting in the front-rear direction are provided on the front and rear edges of the upper portion of each peg 93.

[0038] [An example of how to assemble a connector] Next, an example of a method for assembling the connector 100 will be described. As shown in FIGS. 8 and 9, first, the terminal fittings 11 are attached to each cavity 91D of the inner housing 91 from the rear. For example, the gripping portion 11C is gripped from the rear by a jig (not shown), and the terminal connecting portion 11A is inserted into the cavity 91D from the rear. At this time, the terminal fittings 11 are adjusted so that the board connecting portion 11E protrudes upward in the upper cavity 91D (see FIG. 9). Then, the terminal fittings 11 are adjusted so that the board connecting portion 11E protrudes downward in the lower cavity 91D (see FIG. 9). With the terminal fittings 11 adjusted in this way, the terminal connecting portions 11A are inserted into the cavities 91D. When the terminal connecting portions 11A reach the correct positions within the cavities 91D, the locking portions 11S pass over the lances 91E facing forward and are locked by the lances 91E (see FIG. 9). This prevents the terminal fitting 11 from coming off from the cavity 91D. In this manner, the terminal fitting 11 is attached to the inner housing 91 with the terminal connecting portion 11A housed in the cavity 91D.

[0039] Next, the press-fit portions 11M of the terminal fittings 11 are attached to the grooves 92C of the outer housing 92 from the rear. First, the housing body 91A of the inner housing 91 to which the terminal fittings 11 are attached is inserted from below into the opening 92E. Then, the press-fit portions 11M are press-fitted into the grooves 92C from the rear (see FIG. 9). At this time, the pair of rectangular portions 11Q (see FIG. 8) of each press-fit portion 11M are pressed from the rear with a jig (not shown). In this way, the press-fit portions 11M are press-fitted into the grooves 92C, thereby connecting the board connecting portion 11E to the outer housing 92. At this time, the protrusions 91F of the inner housing 91 are housed in the housing spaces C formed in the cover portion 92B of the outer housing 92.

[0040] Next, the pegs 93 are attached from above to the attachment recesses 92D formed in the outer housing 92 (see FIG. 8), thus completing the connector 100. In the connector 100, the inner housing 91 and the outer housing 92 are not in direct contact with each other, but are connected via the terminal fittings 11.

[0041] [Action on connector] The connector 100 thus formed has the connection body 11N connected by solder to the electrodes provided on one mounting surface of the circuit board S (see FIG. 9). As shown in FIG. 8, a mating connector P is fitted into the connector 100 to connect the mating terminals T and the terminal connection portions 11A. At this time, if the mating connector P is displaced left / right or up / down relative to the connector 100, the inner housing 91 displaces relative to the outer housing 92 to follow the displacement of the mating connector P.

[0042] 10, when the mating connector P is displaced in the left-right direction, the inner housing 91 is displaced in the left-right direction relative to the outer housing 92. At this time, the first elastic portion 11K of the terminal fitting 11 is elastically deformed, causing the inner housing 91 to be displaced in the left-right direction relative to the outer housing 92.

[0043] For example, if the mating connector P is displaced vertically, as shown in FIG. 11 , the inner housing 91 is displaced vertically relative to the outer housing 92. At this time, the second elastic portion 11L of the terminal fitting 11 is elastically deformed, causing the inner housing 91 to be displaced vertically relative to the outer housing 92. In this manner, the displacement-permitting portion 11D permits relative displacement between the board connection portion 11E and the terminal connection portion 11A. The outer shape of the terminal connection portion 11A is slightly smaller than the inner shape of the cavity 91D. Therefore, when the inner housing 91 is displaced horizontally or vertically relative to the outer housing 92, the terminal connection portion 11A can tilt slightly relative to the cavity 91D. This facilitates flexible connection of the mating connector P with the mating terminal T.

[0044] Next, the effects of this configuration will be illustrated. The terminal fitting 11 has a terminal connection portion 11A in the shape of a rectangular tube that connects to a mating terminal T, a board connection portion 11E that connects to a circuit board S, a displacement-allowing portion 11D that is provided between the terminal connection portion 11A and the board connection portion 11E and that allows relative displacement between the board connection portion 11E and the terminal connection portion 11A, and a gripping portion 11C that is a separate portion from the displacement-allowing portion 11D and is provided behind the terminal connection portion 11A so that it can be gripped from behind.

[0045] According to this configuration, the gripping portion 11C is a separate part from the displacement-allowing portion 11D and can be gripped from behind, so that the terminal fitting 11 can be easily accommodated in the cavity 91D of the inner housing 91 while gripping the gripping portion 11C.

[0046] Grip portion 11C extends rearward in a cantilevered manner. With this configuration, the rear edge of grip portion 11C can be pressed from behind, so that when terminal connection portion 11A is inserted into cavity 91D of inner housing 91, grip portion 11C can be pressed from behind to insert the terminal connection portion 11A into cavity 91D of inner housing 91.

[0047] The terminal fitting 11 has an L-shaped rigid portion 11B that extends rearward and is connected to the rear ends of the adjacent first and second wall portions 11F and 11G, which are among the walls that form the terminal connecting portion 11A. The grip portion 11C is provided so as to be connected to the rear end of the rigid portion 11B. With this configuration, the L-shaped rigid portion 11B prevents relative displacement between the grip portion 11C and the terminal connecting portion 11A. Therefore, when the terminal connecting portion 11A is inserted into the cavity 91D of the inner housing 91, the force applied to the grip portion 11C can be efficiently transmitted to the terminal connecting portion 11A via the rigid portion 11B.

[0048] Displacement-permitting portion 11D includes first elastic portion 11K and second elastic portion 11L that extend in the front-rear direction and are elastically deformable. The rear end of first elastic portion 11K is connected to the rear end of rigid portion 11B, and the rear end of second elastic portion 11L is electrically connected to the board connection portion 11E side, and the front ends of first elastic portion 11K and second elastic portion 11L are connected to each other. With this configuration, the rear end of first elastic portion 11K is connected to the rear end of rigid portion 11B rather than to gripping portion 11C, so even if gripping portion 11C bends relative to rigid portion 11B, this effect can be prevented from reaching displacement-permitting portion 11D.

[0049] In a front view seen from the front, the rigid portion 11B and the first elastic portion 11K are arranged within the range of the outline of the external shape of the terminal connecting portion 11A. With this configuration, when viewed from the front or rear, the rigid portion 11B and the first elastic portion 11K can be arranged so as not to protrude from the terminal connecting portion 11A, making it easy to reduce the external shape of the terminal fitting 11.

[0050] The connector 100 includes a terminal fitting 11, an inner housing 91 having a plurality of cavities 91D for accommodating terminal connecting portions 11A, and an outer housing 92 to which a board connecting portion 11E is connected. With this configuration, the terminal connecting portions 11A can be inserted into the cavities 91D of the inner housing 91 while gripping the gripping portion 11C, making the terminal fitting 11 easy to handle and assemble.

The scope of the present invention is not limited to the embodiments disclosed herein, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0052] Unlike the first embodiment, the press-fit portion of the board connection part and the connection body may extend linearly in the front-rear direction, and the connection body may be inserted into a through-hole formed in the circuit board. In this case, the cavities in the inner housing are arranged in the left-right direction and are formed in three or more rows, one above the other, and the number of holding walls in the outer housing is set to match the number of rows of cavities.

[0053] Unlike the first embodiment, the first elastic portion and the second elastic portion may have the same dimensions in the left-right and up-down directions in the cross section perpendicular to the front-rear direction (ie, a square shape). [Explanation of symbols]
