Description

[Technical Field]

[0001] The present invention relates to a terminal press-fitting jig used to press-fit terminals of a connector into press-fit holes in a circuit board. [Background technology]

[0002] Conventionally, board-mounted connectors have been proposed that have multiple terminals (e.g., press-fit terminals) that are press-fit into multiple through holes (i.e., press-fit holes) provided in a circuit board (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-063017 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional connectors described above, the tip portions of each of the multiple terminals (specifically, the compliant portions of the press-fit terminals) are typically aligned with the through-holes in the circuit board, and the connector is then pressed against the circuit board to attach the connector to the circuit board. However, for example, if the terminals are not simply straight but have a bent shape in which they are bent midway, there is an unavoidable tolerance in the degree of bending of each terminal during manufacturing (so-called manufacturing variation), and therefore a similar tolerance also exists in the position of the tip portions of the terminals (hereinafter referred to as "tip position variation"). Such variation in the tip position of the terminals can hinder the improvement of the workability of attaching the connector to the circuit board. Therefore, there is a need for a jig to assist in the work of attaching a connector to a circuit board, so that the work of attaching a connector to a circuit board can be easily performed even when there is variation in the tip position of the terminals.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a jig that can assist in the operation of press-fitting a terminal into a press-fit hole in a circuit board. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the terminal press-fitting jig according to the present invention has the following features.

[0007] A terminal press-fitting jig used to press-fit terminals of a connector into press-fit holes in a circuit board, a holding portion for holding the connector; a pressing portion that presses the circuit board toward the connector, The holding portion is a terminal holding portion for holding the terminal, and configured to be able to receive the connector along a predetermined receiving direction; The terminal holding portion is The receiving device has a plurality of plate-shaped portions extending upright in the receiving direction, and recesses disposed at the extending ends of the plurality of plate-shaped portions and recessed in the receiving direction, and has an arrangement structure in which the plurality of plate-shaped portions are arranged with gaps between them along an arrangement direction intersecting the receiving direction. It is a jig for press-fitting terminals. [Effects of the Invention]

[0008] According to the jig of the present invention, a connector having terminals (so-called press-fit terminals) configured to be press-fit into press-fit holes (so-called through holes) in a circuit board is attached to the holding portion of the jig, whereby the terminals are held in the terminal holding portion of the holding portion. Specifically, even if the terminals have a bent shape, the bent portions (so-called lead portions) of the terminals fit into the gaps between the multiple plate-like portions of the terminal holding portion, and the bent portions are sandwiched between the plate-like portions, thereby reducing the variation in the tip position of the terminals in the arrangement direction of the multiple plate-like portions. Furthermore, a protruding portion (so-called shoulder portion) protruding from the tip portion of the terminal fits into a recess provided at the extending end of the plate-like portion, thereby reducing the variation in the tip position of the terminals in the receiving direction and the direction perpendicular to the arrangement direction. In other words, the variation in the tip position of the terminals is reduced in at least the two directions mentioned above. This allows the tip portions of the terminals to be properly positioned, making it easy to press the terminals into the press-fit holes in the circuit board. Therefore, the jig having this configuration can assist the operation of press-fitting the terminal into the press-fit hole of the circuit board.

[0009] The present invention has been briefly described above. The details of the present invention will become more apparent from the detailed description of the invention set forth below, taken in conjunction with the accompanying drawings. [Brief explanation of the drawings]

[0011] <Embodiment> Hereinafter, a jig 1 according to an embodiment of the present invention will be described with reference to the drawings. Jig 1 is a jig used to press-fit terminals 50 of connector 2 shown in Fig. 6 into through holes 61 of circuit board 60 shown in Fig. 6. As shown in Fig. 1, jig 1 includes a connector holding portion 10, a terminal holding portion 20, and a pressing portion 30.

[0012] For the sake of convenience, the following definitions are used for the terms "front," "rear," "left," "right," "top," and "bottom," as shown in FIG. 1 and elsewhere. The front-to-back, left-to-right, and up-to-down directions are perpendicular to one another. The up-to-down and left-to-right directions correspond to the "receiving direction" and "arrangement direction" of the present invention, respectively. In preparation for explaining the jig 1 below, the connector 2 and circuit board 60 to be assembled to the jig 1 will first be explained.

[0013] First, the connector 2 will be described. As shown in Fig. 6, the connector 2 includes a housing 40 and a plurality of terminals 50 extending from the housing 40. The housing 40 is made of resin and has a generally rectangular parallelepiped shape that is long in the left-right direction. A positioning protrusion 41 is formed on the bottom surface of the housing 40. The positioning protrusion 41 is to be inserted into a positioning recess 11 (see Fig. 1) of the connector holder 10.

[0014] The terminals 50 are formed by processing a rod-shaped member made of a metal material and having a rectangular cross section. The terminals 50 have a generally L-shaped configuration consisting of a first portion extending linearly forward from the front end surface of the housing 40 and a second portion extending linearly upward from the extending end of the first portion (see also FIG. 9 ). The tip portions of the multiple terminals 50 extending from the housing 40 are arranged at intervals in the left-right and front-rear directions, as shown in FIG. 6 . The terminals 50 have a so-called press-fit structure. Specifically, as shown in FIG. 7 , the tip portions of the terminals 50 are formed with press-fit portions 51 that bulge outward on both the left and right sides. The press-fit portions 51 are press-fitted into through holes 61 in the circuit board 60. The press-fit portions 51 have a hollow portion 52 that penetrates in the front-rear direction. The hollow portion 52 allows the press-fit portions 51 to be elastically deformable in the left-right direction. The press-fit portions 51 bulge outward in the left-right direction but not in the front-rear direction. Furthermore, shoulder portions 53 are formed at the tip of terminal 50, protruding on both the left and right sides, at positions adjacent to the lower side of press-fit portion 51. Shoulder portions 53 are fitted into recesses 23 of terminal holding portion 20 of jig 1 (see FIG. 9). For ease of explanation, the L-shaped portion of terminal 50 between the base portion extending from housing 40 and shoulder portion 53 will be referred to as "lead portion 54" (see FIG. 9).

[0015] As shown in Fig. 6, the circuit board 60 has a flat plate shape. A plurality of through holes 61 are provided in the circuit board 60, corresponding to the press-fit portions 51 of the plurality of terminals 50 of the connector 2, and are arranged at intervals in the left-right and front-rear directions. A pair of left and right positioning holes 62 are formed in the circuit board 60. A pair of left and right boss portions 25 provided on the terminal holding portion 20 of the jig 1 are inserted into the pair of left and right positioning holes 62 (see Fig. 8).

[0016] Next, the configuration of each component constituting the jig 1 will be described in order. First, the connector holding portion 10 will be described. The connector holding portion 10 is a component in the jig 1 that functions to hold the connector 2. The connector holding portion 10 is made of resin or metal, and as shown in FIGS. 1 to 3, has a generally rectangular box shape that is elongated in the left-right direction and opens forward and upward. The connector 2 (housing 40 + multiple terminals 50) is housed in the internal space of the connector holding portion 10 (see FIG. 8). A positioning recess 11 is provided on the bottom wall of the connector holding portion 10 in correspondence with the positioning protrusions 41 of the housing 40. The bottom wall of the connector holding portion 10 is further provided with a pair of left and right positioning protrusions 12 and a pair of left and right positioning protrusions 13 for assembling the terminal holding portion 20.

[0017] The terminal holding portion 20 is a component of the jig 1 that holds multiple terminals 50. The terminal holding portion 20 is made of resin or metal and has a shape that extends in the left-right direction, as shown in FIGS. 1 to 3 . The terminal holding portion 20 has multiple flat plate-like plate portions 21 that extend upright and are arranged in the left-right direction with gaps S between them (see FIGS. 4 and 5 ). The left-right positions of the multiple gaps S arranged in the left-right direction correspond to the left-right positions of the multiple terminals 50 arranged in the left-right direction of the connector 2. Tapered surfaces 22 that extend in the front-rear direction and are inclined so as to widen the upper end opening width (left-right spacing) of the gaps S are formed at both left and right corners of the upper end of each plate-like portion 21 (see FIG. 4 ). The upper end surface of each plate-like portion 21 has multiple notch-like recesses 23 that are recessed downward and extend in the left-right direction and are arranged in the front-rear direction with gaps between them (see FIGS. 4 and 5 ). The front-rear positions of the multiple recesses 23 aligned in the front-rear direction correspond to the front-rear positions of the multiple terminals 50 aligned in the front-rear direction of the connector 2. Tapered surfaces 24 are formed on the front and rear opening edges of each recess 23, extending in the left-right direction and inclined so as to increase the upper end opening width (the spacing in the front-rear direction) of the recess 23 (see FIG. 5). A pair of left and right bosses 25 protruding upward are formed on both left and right ends of the terminal holding portion 20 (see FIG. 1, etc.).

[0018] The pressing portion 30 is a component of the jig 1 that functions to press-fit the terminals 50 of the connector 2 into the through-holes 61 of the circuit board 60. The pressing portion 30 is made of resin or metal, and has a generally flat plate-like shape that is elongated in the left-right direction, as shown in FIG. 1 . The pressing portion 30 is provided with a plurality of receiving holes 31 that are spaced apart in the left-right and front-rear directions, corresponding to the press-fit portions 51 of the terminals 50 of the connector 2. The receiving holes 31 are holes that receive the tips of the terminals 50 that have passed through the through-holes 61 of the circuit board 60. A pair of left and right positioning holes 32 are formed on both left and right ends of the pressing portion 30. A pair of left and right bosses 25 provided on the terminal holding portion 20 are inserted into the pair of left and right positioning holes 32 (see FIG. 8 ). The configuration of each component that constitutes the jig 1 has been described above.

[0019] Next, a procedure for press-fitting the terminals 50 of the connector 2 into the through-holes 61 of the circuit board 60 using the jig 1 will be described.

[0020] 2 and 3, the terminal holding portion 20 is first assembled to the connector holding portion 10. This assembly is achieved by bringing the terminal holding portion 20 close to the connector holding portion 10 from above so that a pair of left and right positioning protrusions 12, 13 provided on the connector holding portion 10 are inserted into positioning recesses (not shown) provided on the bottom surface of the terminal holding portion 20. By assembling the terminal holding portion 20 to the connector holding portion 10, the holding portion 70 is formed.

[0021] 8 to 10, the connector 2 is assembled to the holding portion 70. This assembly is achieved by bringing the connector 2 close to the holding portion 70 from above so that the positioning protrusions 41 of the housing 40 are inserted into the positioning recesses 11 (see FIG. 1) of the holding portion 70 (connector holding portion 10), so that the lead portions 54 of the multiple terminals 50 are inserted into and sandwiched in the multiple gaps S between the multiple plate-like portions 21 of the holding portion 70 (terminal holding portion 20), and so that the shoulder portions 53 of the multiple terminals 50 are fitted into the multiple recesses 23 provided on the upper ends of the multiple plate-like portions 21 of the holding portion 70 (terminal holding portion 20). When the connector 2 is assembled to the holding portion 70, the tapered surfaces 22 (see FIG. 4 ) formed on the plate-like portions 21 guide the lead portions 54 of the terminals 50 toward the corresponding gaps S so that they enter the gaps S, and the tapered surfaces 24 (see FIG. 5 ) formed on the plate-like portions 21 guide the shoulder portions 53 of the terminals 50 toward the corresponding recesses 23 so that they fit into the corresponding recesses 23. When the connector 2 is assembled to the holding portion 70, the lead portions 54 of the terminals 50 enter and are sandwiched in the gaps S between the multiple plate-like portions 21 of the holding portion 70, thereby suppressing displacement of the tips of the terminals 50 in the left-right direction. Furthermore, the shoulder portions 53 of the terminals 50 fit into the recesses 23 provided at the upper ends of the plate-like portions 21, thereby suppressing displacement of the tips of the terminals 50 in the front-rear direction. As a result, the tips of the multiple terminals 50 are positioned relative to the pair of left and right boss portions 25 of the holding portion 70 (terminal holding portion 20).

[0022] Next, the circuit board 60 is assembled to the holding portion 70 to which the connector 2 is assembled. This assembly is achieved by bringing the circuit board 60 close to the holding portion 70 from above so that the pair of left and right boss portions 25 of the holding portion 70 (terminal holding portion 20) are inserted into the pair of left and right positioning holes 62 of the circuit board 60. At this stage, the through holes 61 of the circuit board 60 are positioned above the press-fit portions 51 of the terminals 50, and the press-fit portions 51 of the terminals 50 have not yet been press-fit into the through holes 61 of the circuit board 60. In this way, by inserting the pair of left and right boss portions 25 of the holding portion 70 (terminal holding portion 20) into the pair of left and right positioning holes 62 of the circuit board 60, the multiple through holes 61 of the circuit board 60 are positioned relative to the pair of left and right boss portions 25 of the holding portion 70. In other words, the tips of the multiple terminals 50 and the multiple through holes 61 of the circuit board 60 are both positioned relative to the pair of left and right boss portions 25 of the holding portion 70, and as a result, the tips of the multiple terminals 50 and the multiple through holes 61 of the circuit board 60 are aligned.

[0023] 11 , the pressing portion 30 is pressed against the holding portion 70 so as to sandwich the circuit board 60. This pressing is achieved by pressing the pressing portion 30 from above against the holding portion 70 with the pair of left and right boss portions 25 of the holding portion 70 (terminal holding portion 20) inserted into the pair of left and right positioning holes 32 of the pressing portion 30. As a result, the shoulder portion 53 of the terminal 50 receives an upward force from the bottom surface of the recess 23, and the circuit board 60 receives a downward force from the pressing portion 30, so that the press-fit portions 51 of the multiple terminals 50 are press-fit into the multiple through-holes 61 of the circuit board 60, respectively. Here, with the pair of left and right boss portions 25 of the holding portion 70 inserted into the pair of left and right positioning holes 32 of the pressing portion 30, the tip portions of the multiple terminals 50 are aligned with the multiple receiving holes 31 of the pressing portion 30. As a result, the tip of the terminal 50 that has passed through the through hole 61 of the circuit board 60 (protruding upward from the through hole 61) is reliably received in the receiving hole portion 31 of the pressing portion 30, thereby improving the workability of pressing the circuit board 60 with the pressing portion 30.

[0024] As a result of the above, the multiple terminals 50 of the connector 2 are press-fitted into the multiple through holes 61 of the circuit board 60, completing the connector-equipped board 3 shown in Fig. 12. When removing the connector-equipped board 3 from the jig 1, the connector-equipped board 3 can be easily removed from the jig 1 by applying an external force to the connector-equipped board 3 through the removal hole 14 provided on the bottom surface of the connector holding portion 10.

[0025] <Actions and Effects> As described above, with the jig 1 according to this embodiment, when the connector 2 having terminals 50 (so-called press-fit terminals) configured to be press-fit into through holes 61 of a circuit board 60 is attached to the holding portion 70 of the jig 1, the terminals 50 are held by the terminal holding portion 20 of the holding portion 70. Specifically, the terminal portions (lead portions 54) between the housing 40 of the connector 2 and the tips of the terminals 50 are inserted and sandwiched in the gaps S between the plurality of plate-like portions 21 of the terminal holding portion 20, thereby suppressing displacement of the tips of the terminals 50 in the arrangement direction (left-right direction) of the plurality of plate-like portions 21. Furthermore, the protruding portions (shoulder portions 53) protruding from the tips of the terminals 50 at the terminals 50 at their respective ends are fitted into the recesses 23 provided at the extending ends of the plate-like portions 21, thereby suppressing displacement of the tips of the terminals 50 in the direction (front-rear direction) perpendicular to the receiving direction (up-down direction) and the arrangement direction (left-right direction). This allows the tip of the terminal 50 to be properly positioned, making it possible to easily press-fit the terminal 50 into the through-hole 61 of the circuit board 60 .

[0026] Furthermore, according to the jig 1 of this embodiment, the circuit board 60 is positioned by engaging with the board positioning portion (boss portion 25) of the holding portion 70. Therefore, the terminals 50 can be easily press-fitted into the through holes 61 of the circuit board 60.

[0027] Furthermore, according to the jig 1 of this embodiment, the pressing part 30 is positioned using the board positioning part (boss part 25) used to position the circuit board 60. Therefore, compared to when a dedicated positioning part is used for positioning the pressing part 30, positional deviation due to accumulation of tolerances is reduced, and the workability of pressing the circuit board 60 with the pressing part 30 is improved.

[0028] <Other aspects> It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above-described embodiments, and modifications, improvements, etc. are possible as appropriate. Furthermore, the material, shape, dimensions, number, location, etc. of each component in the above-described embodiments are arbitrary as long as they can achieve the present invention, and are not limited thereto.

[0029] For example, in the above embodiment, the size (left-right spacing) of the gap S between the multiple plate-like portions 21 of the holding portion 70 (terminal holding portion 20) is constant along the extension direction (up-down direction) of the gap S (see FIG. 10). In contrast, as shown in FIG. 13, the size (left-right spacing) of the gap S may vary depending on the position along the extension direction (up-down direction) of the gap S. In the example shown in FIG. 13, the size (left-right spacing) of the gap S is narrow only at the upper end of the gap S near the tip of the terminal 50, and is wide in the portions other than the upper end of the gap S.

[0030] For example, in the above embodiment, the size (left-right spacing) of the gap S between the multiple plate-like portions 21 of the holding portion 70 (terminal holding portion 20) is constant along the extension direction (up-down direction) of the gap S (see FIG. 10). In contrast, as shown in FIG. 13, the size (left-right spacing) of the gap S may vary depending on the position in the extension direction (up-down direction) of the gap S. In the example shown in FIG. 13, the size (left-right spacing) of the gap S is narrow only at the upper end of the gap S near the tip of the terminal 50, and is wide in the portions other than the upper end of the gap S. This reduces the frictional force generated between the terminal 50 and the plate-like portions 21 when the terminal 50 is inserted into the gap S, thereby facilitating the insertion of the terminal 50.

[0031] Furthermore, in the above embodiment, the boss 25 of the holding portion 70 is inserted into the positioning hole 62 of the circuit board 60, thereby engaging the boss 25 with the positioning hole 62. Alternatively, a boss may be provided on the circuit board 60, and a positioning hole may be provided on the holding portion 70. Alternatively, without using such a boss, the peripheral edge of the circuit board 60 may be engaged with the opening edge of the connector holding portion 10, thereby aligning the two.

[0032] Here, the features of the embodiment of the jig 1 according to the present invention described above will be briefly summarized and listed below in [1] to [3].

Specifically, even if the terminals have a bent shape, the bent portions (so-called lead portions) of the terminals fit into the gaps between the multiple plate-like portions of the terminal holding portion, and the bent portions are sandwiched between the plate-like portions, thereby reducing the variation in the tip position of the terminals in the arrangement direction of the multiple plate-like portions. Furthermore, the protruding portions (so-called shoulder portions) protruding from the tip portions of the terminals are fitted into the recesses provided at the extending ends of the plate-like portions, thereby reducing the variation in the tip position of the terminals in the receiving direction and the direction perpendicular to the arrangement direction. In other words, the variation in the tip position of the terminals is reduced in at least the two directions mentioned above. This allows the tip portions of the terminals to be properly positioned, making it easy to press the terminals into the press-fit holes in the circuit board. Therefore, the jig having this configuration can assist the operation of press-fitting the terminal into the press-fit hole of the circuit board.

[0036] According to the jig having the configuration [2] above, the circuit board is positioned by engaging with the board positioning portion (e.g., the protrusion) of the holding portion, so that the terminals can be easily press-fitted into the press-fit holes of the circuit board.

[0037] [3] In the jig (1) described in [2] above, The pressing portion (30) is The terminal (50) further includes a receiving hole (31) for receiving the tip of the terminal (50) that has passed through the press-fit hole (61) of the circuit board (60), and a pressing portion positioning portion (32) that engages with the board positioning portion (25) to align the receiving hole (31) with the tip of the terminal (50).
