Description

[Technical Field]

[0001] The present invention relates to a board-mounted connector, a connector mounting structure, and a reinforcing tab. [Background technology]

[0002] The electrical connector with locking fittings disclosed in Patent Document 1 includes a locking fitting that is press-fitted into a connector housing. A pin-shaped fixing portion on the locking fitting protrudes from the bottom surface of the connector housing and is soldered to a through-hole in the board, thereby fixing the connector housing to the board.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-135415 Summary of the Invention [Problem to be solved by the invention]

[0004] If cracks occur in the soldered portion where the fixing portion is soldered due to external force or heat after the electrical connector is mounted on the board, the strength of the connection between the connector housing and the board will decrease. In this state, if the soldered portion where the lead portion of the terminal is soldered to the board is subjected to external force, it will cause poor conductivity.

[0005] An embodiment of the present invention provides a board-mounted connector, a connector mounting structure, and a reinforcing tab that can improve the connection strength between a circuit board and a housing. [Means for solving the problem]

[0006] A preferred embodiment of the present invention provides a board-mounted connector (1; 1P) to be mounted on a circuit board (10) including a pair of through holes (12; 12P), the board-mounted connector comprising: terminals (2) mounted on the circuit board; a housing (3) including a pair of side walls (34; 34P) for holding the terminals; and a pair of reinforcing tabs (4) formed by a pair of metal side plates. Each of the reinforcing tabs includes a reinforcing tab body (5), a fixed portion (6), and a connecting portion (7). The reinforcing tab body includes one end (51) configured to be inserted into the corresponding through hole and soldered, a depressible other end (52), an intermediate portion (53) between the one end and the other end, and a locking projection (54) formed on the one end. The fixed portion is fixed to the corresponding side wall of the housing. The connecting portion connects the fixed portion to the intermediate portion of the reinforcing tab body. The connecting portion includes a fulcrum portion (SP) that supports the reinforcing tab body so that it can be elastically oscillated between an upright position in a free state and an inclined position in which the other end is pressed laterally. When each reinforcing tab is in the inclined position, the locking protrusion is configured to be insertable into the corresponding through hole, and when each reinforcing tab is in the upright position, the locking protrusion is configured to be lockable with the edge portion (12Se) of the corresponding through hole to prevent it from coming off.

[0007] According to this configuration, the locking projection of the reinforcing tab, which is in an inclined position while the other end of the reinforcing tab body is pressed, is inserted into the through-hole of the circuit board, and then the pressing operation is released to return the reinforcing tab body to an upright position, and the locking projection is locked onto the edge of the through-hole to prevent it from coming out, thereby improving the connection strength between the circuit board and the housing.

[0008] In one preferred embodiment, the locking projections of each of the reinforcing tab bodies include a pair of locking projections (54, 54) that project in opposite directions in the front-rear direction. This configuration can further improve the strength with which the housing is connected to the circuit board.

[0009] In one preferred embodiment, the fixed portions include a pair of fixed portions (6, 6) arranged to sandwich the intermediate portion of the reinforcing tab main body from the front and rear. The connecting portion includes a pair of connecting portions (7, 7) that respectively connect the pair of fixed portions to the intermediate portion of the reinforcing tab main body. This configuration allows the reinforcing tab main body to be stably supported while swinging. In one preferred embodiment, each of the connecting portions includes a redundant portion (J) that is longer than the linear distance between the corresponding fixed portion and the intermediate portion of the reinforcing tab main body. According to this configuration, the connecting portion including the fulcrum portion includes the redundant portion, so that the reinforcing tab main body can be elastically supported so as to be able to swingably displace.

[0010] In one preferred embodiment, when each of the reinforcement tabs is in the inclined position, the locking projections can be inserted into the corresponding through holes without interfering with each other. This configuration suppresses vibrations in the circuit board when the locking projections are inserted into the through holes, thereby suppressing misalignment of components placed on the circuit board before mounting.

[0011] In one preferred embodiment, the housing includes a pair of grippable portions (HH) that, when gripped, can regulate the amount of pressure applied to the other ends of the reinforcing tab bodies of the pair of reinforcing tabs. With this configuration, the action of gripping the pair of grippable portions to transport the board-mounted connector also serves as the action of swinging the reinforcing tab bodies to an inclined position to insert the locking protrusions into the corresponding through-holes. This simplifies the process of attaching the board-mounted connector to a circuit board. Furthermore, by precisely regulating the amount of pressure applied to the other ends of the reinforcing tab bodies, it is possible to reliably achieve a state in which the locking protrusions can be inserted into the corresponding through-holes without interference.

[0012] Another embodiment of the present invention provides a connector mounting structure (100) including a circuit board including a pair of through holes and the board-mounted connector mounted on the circuit board. This configuration makes it possible to realize a connector mounting structure with high connection strength between the circuit board and the housing.

[0013] Another embodiment of the present invention provides a reinforcing tab formed of a metal side plate, used to reinforce the strength of a connection between a housing of a board-mounted connector and a circuit board. The reinforcing tab includes a reinforcing tab body including one end that can be inserted into a through hole of the circuit board and soldered, an opposite end that can be pressed, an intermediate portion between the one end and the other end, and a locking protrusion formed on the one end. The reinforcing tab also includes a fixed portion that is fixed to a corresponding side wall of the housing, and a connecting portion that connects the fixed portion to the intermediate portion of the reinforcing tab body. The connecting portion includes a fulcrum portion that supports the reinforcing tab body so that it can resiliently swing between an upright position in a free state and an inclined position in which the other end is pressed. This configuration allows the reinforcing tab to be used in a board-mounted connector to improve the connection strength between the circuit board and the housing.

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0016] Fig. 1 is a perspective view of a board-mounted connector 1 and a circuit board 10 according to one embodiment of the present invention. Fig. 2A is a perspective view of a connector mounting structure 100 including the board-mounted connector 1 and the circuit board 10. Fig. 2B is a vertical cross-sectional view of the connector mounting structure 100 taken along the left-right direction.

[0017] 1, 2A, and 2B, the circuit board 10 includes a front surface 10a, a back surface 10b, multiple rows of first through holes 11 for inserting terminals, and a pair of second through holes 12 for inserting reinforcing tabs. The front surface 10a of the circuit board 10 extends in the front-rear direction X and the left-right direction Y of the board-mounted connector 1. The forward direction X1 of the front-rear direction X corresponds to the mating direction of the board-mounted connector 1, and the rear direction X2 of the front-rear direction X corresponds to the opposite direction to the mating direction. The upward direction Z of the board-mounted connector 1 corresponds to the height direction Z1.

[0018] Fig. 3 is a perspective view of the board-mounted connector 1. Fig. 4 is a front view of the reinforcing tab 4. Fig. 5 is a bottom view of the main part of the circuit board 10.

[0019] As shown in FIG. 3, the board-mounted connector 1 includes terminals 2, a housing 3 that holds the terminals 2, and a pair of metal reinforcing tabs 4 that reinforce the strength with which the housing 3 is connected to the circuit board 10.

[0020] First, the reinforcing tab 4 will be described. As shown in Fig. 4, each reinforcing tab 4 includes a reinforcing tab main body 5 formed of a side plate, a pair of fixed portions 6, and a pair of connecting portions 7. The reinforcing tab main body 5 includes one end 51 as an insertion end that can be inserted into the second through-hole 12, the other end 52 that can be pressed, an intermediate portion 53 between the one end 51 and the other end 52, a pair of locking protrusions 54 that are disposed at the one end 51 and protrude forward X1 and backward X2, respectively, an outer surface 5a, and an inner surface 5b.

[0021] The pair of fixed portions 6 are downward-facing pieces arranged on either side of the intermediate portion 53 in the front-rear direction X, and have a symmetrical shape with respect to the reinforcing tab main body 5. Each fixed portion 6 includes a press-fit protrusion 61, and is press-fitted and fixed to the support rib 35 of the corresponding extended side wall 37 of the housing 3 (see FIG. 10B).

[0022] The pair of connecting portions 7 connect each of the pair of fixed portions 6 to the intermediate portion 53 of the reinforcing tab main body 5. Each connecting portion 7 includes a fulcrum portion SP (see FIG. 11A) that supports the reinforcing tab main body 5 so that it can elastically swing and displace in a seesaw shape.

[0023] Each connecting portion 7 includes a redundant portion J that is longer than the linear distance between the upper end of the fixed portion 6 and the intermediate portion 53 of the reinforcing tab main body 5. Specifically, the redundant portion J includes a crank-shaped portion K. The crank-shaped portion K includes a first extending portion 71, a second extending portion 72, a third extending portion 73, an R-shaped first curved portion 74, and an R-shaped second curved portion 75.

[0024] The first extending portion 71 extends in the front-rear direction X from the upper end of the fixed portion 6. The second extending portion 72 extends downward Z2 in the up-down direction Z from the extending end 71a of the first extending portion 71 via the first curved portion 74. The third extending portion 73 extends in the front-rear direction X from the extending end 72a of the second extending portion 72 via the second curved portion 75, and is connected to the intermediate portion 53 of the reinforcing tab main body 5. The third extending portions 73 of the pair of connecting portions 7 form a fulcrum portion SP that supports the reinforcing tab main body 5 so that it can elastically swing and displace in a seesaw shape.

[0025] As shown in Fig. 5, the pair of second through holes 12 includes a wide portion 12L having a large width in the front-rear direction X and a narrow portion 12S that communicates with the inside of the wide portion 12L and has a width narrower than that of the wide portion 12L in the front-rear direction X. The widthwise center of the wide portion 12L and the widthwise center of the narrow portion 12S coincide with each other (see the dashed line in Fig. 5). On the back surface 10b (bottom surface) of the circuit board 10, a pair of locking protrusions 54 (see Fig. 4) on one end 51 of the reinforcing tab main body 5 of the corresponding reinforcing tab 4 can be locked with a pair of edge portions 12Se in the front-rear direction X of the narrow portion 12S of the second through hole 12 (see Fig. 10B).

[0026] Fig. 6A is a plan view of the board-mounted connector 1, and Fig. 6B is a front view of the board-mounted connector 1. Fig. 7A is a rear view of the board-mounted connector 1, and Fig. 7B is a bottom view of the board-mounted connector 1. Fig. 8A is a left side view of the board-mounted connector 1, and Fig. 8B is a right side view of the board-mounted connector. Fig. 9A is a plan cross-sectional view of the board-mounted connector 1, and Fig. 9B is an enlarged cross-sectional view of a portion of Fig. 9A. Fig. 10A is a longitudinal cross-sectional view along the front-rear direction of the connector coupling structure, and Fig. 10B is an enlarged cross-sectional view of a portion of Fig. 10A.

[0027] 6B, the board-mounted connector 1 includes a row of upper terminals 2U, middle terminals 2M, and lower terminals 2L as terminals 2. The upper terminals 2U, middle terminals 2M, and lower terminals 2L are collectively referred to simply as terminals 2.

[0028] As shown in FIG. 9A, the terminal 2 is an insertion-mount type terminal including a terminal body 20 having a fixed portion 21 and a male terminal portion 22 and extending in the front-rear direction X, and a lead portion 23 connected to the circuit board 10 (see FIGS. 1 and 2B). The fixed portion 21 is press-fitted and fixed into the housing 3. As shown in FIG. 9B, the fixed portion 21 includes a press-fit protrusion 21a and a positioning protrusion 21b that determines the press-fit position of the fixed portion 21. The male terminal portion 22 extends forward from the fixed portion 21 in the mating direction X1 and protrudes into the insertion recess S1 of the housing 3. The male terminal portion 22 is mated with a corresponding mating female terminal portion (not shown).

[0029] 3, the lead portion 23 includes an inclined portion 24 and a mounting portion 25. The inclined portion 24 extends diagonally downward from the rear end 20a of the terminal body 20 that protrudes from the rear wall 33 of the housing 3. The mounting portion 25 extends downward Z2 in the up-down direction Z from the extending end 24a (lower end) of the inclined portion 24, and is inserted into a corresponding first through-hole 11 (see FIG. 1) of the circuit board 10 for mounting.

[0030] As shown in Fig. 6B, in the height direction Z1, the male terminal portions 22 of the terminal bodies 20 of the upper terminals 2U, the male terminal portions 22 of the terminal bodies 20 of the middle terminals 2M, and the male terminal portions 22 of the terminal bodies 20 of the lower terminals 2L are assembled to the housing 3 at positions in the Z direction that decrease in height in that order. Also, as shown in Fig. 7B, in the front-rear direction X, the mounting portions 25 of the upper terminals 2U, the mounting portions 25 of the middle terminals 2M, and the mounting portions 25 of the lower terminals 2L approach the rear wall 33 of the housing 3 in that order. Also, as shown in Fig. 6A, in a plan view, the lead portions 23 of the upper terminals 2U, the lead portions 23 of the middle terminals 2M, and the lead portions 23 of the lower terminals 2L are alternately arranged in this order in the left-right direction Y.

[0031] Next, we will explain the housing 3. As shown in Figures 3 and 6B, the housing 3 includes a top wall 31, a bottom wall 32, a rear wall 33, a pair of side walls 34 each including an extending side wall 37, an insertion recess S1 (see also Figure 9A), a pair of support ribs 35, and a pair of grippable ribs 36.

[0032] As shown in FIGS. 6B and 9A, the top wall 31, the bottom wall 32, and the pair of side walls 34 form an insertion recess S1 into which a mating housing (not shown) of a mating connector is inserted and fitted.

[0033] 3 and 6A, the pair of side walls 34 includes a pair of extending side walls 37 that extend rearward beyond the rear wall 33. The pair of extending side walls 37 are arranged on both sides of the lead portions 23 of the terminals 2 (upper terminal 2U, middle terminal 2M, and lower terminal 2L) in the left-right direction Y, and function as a pair of protective walls that protect the lead portions 23 of the terminals 2. As shown in FIG. 6A, each extending side wall 37 includes an outer surface 37a and an inner surface 37b.

[0034] 3 and 6A, the pair of support ribs 35 are a pair of vertical ribs formed to protrude from the outer surfaces 37a of the pair of extending side walls 37 at positions sandwiching the reinforcing tab body 5 in the front-rear direction X. As shown in FIG. 10B, each of the pair of support ribs 35 includes a fixing groove 35a that opens upward. The corresponding fixed portions 6 of the reinforcing tab 4 are press-fitted and fixed into the fixing grooves 35a of the pair of support ribs 35. In this way, the pair of support ribs 35 fix and support the pair of fixed portions 6 of the reinforcing tab 4.

[0035] 3, 8A, and 8B, the pair of grippable ribs 36 are a pair of vertical ribs formed to protrude from the outer surfaces 37a of the pair of extending side walls 37 at positions sandwiching the reinforcing tab body 5 in the front-rear direction X. The pair of grippable ribs 36 are disposed higher in the Z1 direction than the pair of support ribs 35.

[0036] 11A and 11B are installation process diagrams of the board-mounted connector 1. Figures 12A and 12B are cross-sectional views sequentially showing the behavior of the reinforcing tab 4 when it is locked to the circuit board 10. Figures 13A and 13B are schematic plan views sequentially showing the behavior of the other end 52 of the reinforcing tab 4 before and after it is gripped by a pressing operation.

[0037] As shown in FIG. 11A, the outer surfaces 36a of the pair of grippable ribs 36 function as a pair of grippable parts HH that can be gripped by a pair of gripping parts (not shown) or a robot hand (RH) as shown in FIG. 13B. The pair of grippable parts HH correspond to clamped parts because they are clamped from the outside by the pair of gripping parts.

[0038] 13B, the outer surfaces 36a of the pair of grippable ribs 36 are gripped together with the outer surfaces 5a of the other ends 52 of the reinforcing tab bodies 5 of the pair of reinforcing tabs 4, thereby functioning as a restricting portion R that restricts the amount of pressing operation of the other ends 52 of the reinforcing tab bodies 5 of the pair of reinforcing tabs 4. In other words, each grippable rib 36 includes the outer surface 36a that functions as the restricting portion R and the grippable portion HH (sandwiched portion).

[0039] 11A, the locking protrusion 54 of the reinforcing tab main body 5, which is in an inclined position while the other end 52 of the reinforcing tab main body 5 is pressed, is inserted into the wide portion 12L (see FIG. 12A) of the second through-hole 12 of the circuit board 10, and then the pressing of the other end 52 is released to return the reinforcing tab main body 5 to an upright position as shown in FIGS. 11B and 12B, and the locking protrusion 54 is locked into the edge portion 12Se (see FIG. 10B) of the narrow portion 12S of the second through-hole 12. This prevents the reinforcing tab 4 from coming off the second through-hole 12, improving the connection strength between the circuit board 10 and the housing 3.

[0040] 10B, the reinforcing tab body 5 includes a pair of locking protrusions 54 that protrude forward and backward. With this configuration, the strength with which the housing 3 is connected to the circuit board 10 can be further improved.

[0041] The reinforcing tab 4 also includes a pair of fixed portions 6 arranged to sandwich the intermediate portion 53 of the reinforcing tab main body 5 in the front-rear direction X, and a pair of connecting portions 7 that respectively connect the pair of fixed portions 6 to the intermediate portion 53 of the reinforcing tab main body 5. This configuration allows the reinforcing tab main body 5 to be stably supported while swinging.

[0042] Furthermore, each connecting portion 7 includes a redundant portion J that is longer than the linear distance between the corresponding fixed portion 6 and the intermediate portion 53 of the reinforcing tab main body 5. According to this configuration, the connecting portion 7 including the fulcrum portion SP includes the redundant portion J, thereby enabling the reinforcing tab main body 5 to be elastically supported so as to be able to swingably displace. Note that, instead of the crank-shaped portion K, an S-shaped portion or a dogleg-shaped portion (not shown) may be used as the redundant portion J.

[0043] 11A and 12A, when each reinforcing tab body 5 is in an inclined position, the locking protrusions 54 can be inserted into the corresponding second through-holes 12 without interfering with each other. This configuration prevents vibrations from occurring in the circuit board 10 when the locking protrusions 54 are inserted into the second through-holes 12 (wide portions 12L). This prevents misalignment of components (not shown) placed on the circuit board 10 before mounting.

[0044] The housing 3 includes a pair of grippable portions HH (corresponding to the outer surfaces 36a of the grippable ribs 36, also functioning as regulating portions R) that can regulate the amount of pressure applied to the other ends 52 of the reinforcing tab bodies 5 of the pair of reinforcing tabs 4 when the housing 3 is gripped.

[0045] With this configuration, the action of gripping the pair of gripped portions HH in order to transport the board-mounted connector 1 also serves as the action of swinging and displacing the reinforcing tab main body 5 into an inclined position in order to insert the locking projections 54 into the corresponding second through-holes 12. This simplifies the process of attaching the board-mounted connector 1 to the circuit board 10. Furthermore, the amount of pressure applied to the other end 52 of the reinforcing tab main body 5 can be precisely regulated, ensuring that the locking projections 54 can be inserted into the corresponding second through-holes 12 without interference.

[0046] Furthermore, according to the configuration of the connector mounting structure 100 including the board-mounted connector 1 and the circuit board 10, a connector mounting structure in which the connection strength between the circuit board 10 and the housing 3 is high can be realized.

[0047] Furthermore, the configuration of the reinforcing tab 4 makes it possible to use the reinforcing tab 4 in the board-mounted connector 1 to improve the strength of the connection between the circuit board 10 and the housing 3.

[0048] Next, Fig. 14 is a perspective view of a board mounted connector 1P according to another embodiment of the present invention. Fig. 15 is a schematic view of the mounting process of the board mounted connector 1P.

[0049] The board-mounted connector 1P in Fig. 14 differs from the board-mounted connector 1 in Fig. 3 mainly in the following respects. That is, a pair of support ribs 35P that fix and support a pair of fixed portions of the corresponding reinforcing tab 4 are formed to protrude from an inner surface 37Pb of an extending side wall 37P of each side wall 34P of the board-mounted connector 1P. Also, a pair of grippable ribs 36P are formed to protrude from the inner surface 37Pb of each extending side wall 37P. The inner surface 36Pb of each grippable rib 36P functions as a grippable portion HH that is spread and gripped, and also functions as a restricting portion R that restricts the amount of pressure applied in the spreading direction to the other end 52 of the reinforcing tab main body 5 of the reinforcing tab 4.

[0050] 15, by using a robot hand (not shown) to press and spread apart the other ends 52 of the pair of reinforcing tab bodies 5, the locking protrusions 54 on one ends 51 of the pair of reinforcing tab bodies 5 can be inserted without interference into the wide portions 12L of the pair of second through holes 12P of the circuit board 10P. In the circuit board 10P, the pair of second through holes 12P include wide portions 12L on sides closer to each other and narrow portions 12S on sides farther from each other.

[0051] 15 , the other end 52 of the reinforcing tab main body 5 is pressed to insert the locking protrusion 54 of the reinforcing tab main body 5, which is in an inclined position, into the wide portion 12L of the second through-hole 12P of the circuit board 10P. Thereafter, although not shown, the pressing of the other end 52 is released to return the reinforcing tab main body 5 to an upright position, and the locking protrusion 54 is locked into the edge portion 12Se of the narrow portion 12S of the second through-hole 12P. This prevents the reinforcing tab 4 from coming off the second through-hole 12P, improving the connection strength between the circuit board 10P and the housing 3.

[0052] Furthermore, with each reinforcing tab body 5 in an inclined position, the locking protrusions 54 can be inserted into the corresponding second through-holes 12P without interfering with each other. This configuration prevents vibrations from occurring in the circuit board 10P when the locking protrusions 54 are inserted into the second through-holes 12P (wide portions 12L). This prevents misalignment of components (not shown) placed on the circuit board 10P before mounting.

[0053] In addition, the housing 3 includes a pair of grippable portions HH (corresponding to the inner surfaces 36Pb of the grippable ribs 36P, which also function as regulating portions R) that can regulate the amount of pressure applied to the other ends 52 of the reinforcing tab bodies 5 of the pair of reinforcing tabs 4 when the housing 3 is held open.

[0054] With this configuration, the action of spreading and gripping the pair of gripped portions HH in order to transport the board-mounted connector 1P also serves as the action of swinging and displacing the reinforcing tab main body 5 into an inclined position in order to insert the locking protrusions 54 into the corresponding second through-holes 12. This simplifies the process of attaching the board-mounted connector 1P to the circuit board 10P. Furthermore, the amount of pressure applied to the other end 52 of the reinforcing tab main body 5 can be precisely regulated, ensuring that the locking protrusions 54 can be inserted into the corresponding second through-holes 12 without interference.

[0055] The present invention is not limited to the above-described embodiments, and for example, in each of the above-described embodiments, the terminal 2 may be a surface-mount terminal. In addition, various modifications can be made to the present invention within the scope of the claims. [Explanation of symbols]
