The press-fit terminal has a shoulder portion that protrudes in the left and right directions orthogonal to the axial direction of the press-fit terminal. The shoulder portion is inserted into a hole of the male housing. In addition, the press-fit terminal has a press-fit portion below the shoulder portion.

Such a press-fit terminal is also disclosed in Patent Documents 2 and 3. Prior Art Documents Patent Documents

[0003] Patent Document 1: Japanese Unexamined Patent Application Publication No. 10-154542 Patent Document 2: Japanese Unexamined Patent Application Publication No. 2006-4642 Patent Document 3: Japanese Unexamined Patent Application Publication No. 2015-46238 Summary of the Invention Problems to be Solved by the Invention

[0004] In the case of Patent Document 1, the shoulder portion is pressed into the male housing from above by a jig, the shoulder portion is inserted into the hole of the male housing, and the press-fit portion is inserted into the through hole of the substrate. Therefore, before assembling the press-fit terminal, it is necessary to previously set the male housing and the substrate in a positioned state.

[0005] In addition, when the male housing is engaged with the female housing and the engaging force acts on the shoulder portion, there is a possibility that the shoulder portion is inclined in the hole, and thus the shoulder portion, the press-fit portion, etc. are deformed.

[0006] In contrast, the following structure can be adopted: a press-fit portion is provided at the front end portion in the axial direction of the press-fit terminal, a locking portion having a locking structure for locking with the male housing is provided at the rear end portion, and a shoulder portion for pressing the press-fit portion into the through hole of the substrate is provided between the locking portion and the press-fit portion. If such a structure is adopted, since the locking portion is locked with the male housing, the possibility of deformation of the press-fit terminal during the engagement of the connector can be reduced. In addition, since the locking portion and the shoulder portion can be independently pressed, it is not necessary to previously set the male housing and the substrate in a positioned state. However, when the locking portion and the shoulder portion aligned in the axial direction are both shaped to protrude in the left and right directions, the locking portion covers the shoulder portion from above, so there is a problem that the shoulder portion cannot be pressed from above by a jig.

[0007] Therefore, an object of the present invention is to provide a structure that can prevent deformation of the press-fit terminal and can press the shoulder portion without obstruction when assembling the substrate. Solution to the problem

[0008] The present invention relates to a press-fit terminal having a shaft portion extending in the axial direction. The press-fit terminal includes: a press-fit portion located at the front end of the shaft portion in the axial direction, which can elastically deform in a direction orthogonal to the axial direction; a shoulder portion located behind the press-fit portion in the axial direction and protruding from the shaft portion in a direction orthogonal to the axial direction; and a claw-shaped locking portion located behind the shoulder portion in the axial direction and protruding from the shaft portion in a direction orthogonal to the axial direction. The shoulder portion and the locking portion are arranged in a misaligned manner so as not to overlap each other when viewed from the rear in the axial direction.

[0009] In addition, the present invention relates to a connector including a housing in which the above-described press-fit terminal is mounted. The press-fit portion is connected to a through-hole of a substrate, and a locking hole for locking the locking portion is formed in the housing. Advantages of the invention

[0010] According to the present invention, a structure that can prevent deformation of the press-fit terminal and press the shoulder portion without obstruction can be provided. Description of the drawings

[0012] [Description of the embodiment of the present invention] First, embodiments of the present invention will be described by way of example. The press-fit terminal of the present invention, (1) It has a shaft portion extending in the axial direction. The press-fit terminal has: a press-fit portion located at the front end portion which is the tip portion in the axial direction of the shaft portion, capable of elastically deforming in a direction orthogonal to the axial direction; a shoulder portion located behind the press-fit portion in the axial direction, protruding from the shaft portion in a direction orthogonal to the axial direction; and a claw-shaped locking portion located behind the shoulder portion in the axial direction, protruding from the shaft portion in a direction orthogonal to the axial direction. The shoulder portion and the locking portion are arranged in a misaligned manner so as not to overlap each other when viewed from the rear in the axial direction.

[0013] Since the shoulder portion and the locking portion are arranged in a misaligned manner so as not to overlap each other when viewed from the rear, when the press-fit portion is inserted (pressed) into the through hole of the substrate and connected thereto, the shoulder portion can be pressed from the rear by a jig. In addition, when the press-fit terminal is assembled to the connector, the locking portion can be locked to the housing. Therefore, when the connector is engaged with the mating connector and the engagement force acts on the locking portion, the locking portion can be prevented from tilting relative to the housing. As a result, the situation where the locking portion or the press-fit portion is deformed by the engagement force can be prevented.

[0014] (2) In the press-fit terminal described in the above (1), preferably, it has a torsion portion located between the shoulder portion and the locking portion, and is twisted around the axis in a manner that generates the non-overlapping misalignment.

[0015] When manufacturing the press-fit terminal, the torsion portion can be easily formed by performing a torsion process after blanking the conductive sheet into a predetermined shape.

[0016] (3) In the press-fit terminal described in the above (1) or (2), preferably, the shaft portion has a displacement allowance portion at a position overlapping with the locking portion in the axial direction, which allows elastic displacement of the locking portion.

[0017] When assembling the press-fit terminal, first, when the locking portion is locked to the housing, the housing covers the shoulder portion from the rear. Therefore, even in this state, when the press-fit portion is connected to the through hole of the substrate, the shoulder portion cannot be pressed by a jig. Therefore, as an assembly step of the press-fit terminal, it is required to lock the locking portion to the housing after connecting the press-fit portion to the through hole of the substrate. Here, assuming that the locking force of the locking portion relative to the housing is greater than the holding force of the press-fit portion relative to the substrate, during the process of assembling the press-fit terminal to the housing, it is possible that the press-fit portion detaches from the through hole of the substrate. In this regard, according to the structure of the above (3), since the shaft portion has a displacement allowance portion that allows elastic displacement of the locking portion, the locking force of the locking portion relative to the housing can be reduced by using the displacement allowance portion. While ensuring a predetermined locking force for the locking portion, the situation where the press-fit portion detaches from the through hole of the substrate during the assembly of the housing can be avoided.

[0018] (4) In the press-fit terminal described in the above (3), preferably, the displacement allowance portion is a hole that penetrates the shaft portion in a direction orthogonal to the axial direction.

[0019] According to the structure of the above (4), by performing a process of punching the shaft portion, the hole serving as the displacement allowance portion can be easily formed.

[0020] (5) In the press-fit terminal described in the above (4), preferably, the locking portions are protrudingly provided along the axial direction of the shaft portion, and the displacement allowance portion is a long hole that is longer in the axial direction than in the direction orthogonal to the axial direction.

[0021] Since the displacement allowance portion is a long hole that is long in the axial direction, elastic displacements of the plurality of locking portions arranged in the axial direction can be allowed together, and simplification of the structure can be achieved.

[0022] (6) A connector includes a housing, in which the press-fit terminal described in any one of the above (1) to (5) is mounted, the press-fit portion is connected to a through hole of a substrate, and a locking hole that locks with the locking portion is formed in the housing.

[0023] A jig can be used to press the shoulder portion so that the press-fit portion is inserted into the through hole of the substrate and connected thereto. Then, the locking portion can be inserted into the locking hole of the housing and locked thereto.

[0024] [Details of Embodiments of the Present Invention] The following describes specific examples of the present invention with reference to the drawings. In addition, the present invention is not limited to this illustration, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0025] <Embodiment 1> As Figure 1 shown, the connector 10 of Embodiment 1 includes: a plurality of press-fit terminals 20 that are connected to a rigid substrate 100 such as a printed circuit board; and a housing 60 that mounts each press-fit terminal 20. The press-fit terminal 20 has a shaft portion 21 that extends in the axial direction. The shaft portion 21 is a portion that extends in the axial direction, and in the case of the present Embodiment 1, it is formed so as to extend over the entire length of the press-fit terminal 20. The housing 60 is placed and supported on the surface of the substrate 100. In addition, in the following description, regarding the front-rear direction, the front in the axial direction of the press-fit terminal 20 is defined as the front. The front is also the direction in which the substrate 100 is located with respect to the housing 60. The left-right direction is based on the left-right direction of Figure 4 . The left-right direction is synonymous with the width direction. The up-down direction is based on Figure 1 and Figure 2Based on the left - right direction. In the following description of the structure of the press - fit terminal 20, the direction orthogonal to the axial direction also includes either the left - right direction or the up - down direction. In each figure, the reference sign X represents the front, the reference sign Y represents the right, and the reference sign Z represents the top. The reference for these directions is for convenience and does not necessarily coincide with the reference for the direction when the connector 10 is mounted on a vehicle (not shown) or the like.

[0026] (Housing 60) The housing 60 is made of synthetic resin and, as Figure 1 shown, has a flat - plate - shaped base portion 61 in the left - right direction and a cover portion 62 protruding rearward from the base portion 61. The cover portion 62 is in the shape of a cylinder that is long in the up - down direction. The cover portion 62 fits into a mating connector (not shown) from the rear. The base portion 61 is in the shape of a horizontal plate. A plurality of locking holes 63 are formed through the base portion 61 in the front - rear direction (the plate - thickness direction). Each of the locking holes 63 is arranged in multiple columns in the left - right direction and multiple layers in the up - down direction ( Figure 1 the paper - thickness direction of the drawing). As Figure 2 shown, an introduction portion 64 that expands forward is formed at the front - end side of each locking hole 63 of the base portion 61. The locking portion 29 (described later) of the press - fit terminal 20 is inserted into the locking hole 63 from the introduction portion 64 and locked thereto.

[0027] Although not shown in detail, the housing 60 has a plurality of leg portions 65 protruding downward from the four - corner portions on the outer - peripheral side of the base portion 61. Each leg portion 65 is supported on the substrate 100 and is fixed to the substrate 100 by tightening bolts (not shown) passing through each leg portion 65. The base portion 61 is arranged in parallel with a space therebetween from the surface (rear surface) of the substrate 100 via each leg portion 65.

[0028] (Press - fit terminal 20) The press - fit terminal 20 is integrally formed by blanking a conductive metal plate or the like. As Figures 3 to 5 shown, the shaft portion 21 of the press - fit terminal 20 has tapered narrowing portions 22 that taper toward the end at the foremost end portion and the rearmost end portion in the axial direction.

[0029] The front - end portion of the shaft portion 21 of the press - fit terminal 20 has a press - fit portion 23 behind the tapered narrowing portion 22. The press - fit portion 23 is inserted into the through - hole 101 of the substrate 100 and electrically connected to a conductive portion (not shown) of the substrate 100.

[0030] As Figure 3 and Figure 4As shown, the press-fitting portion 23 has: a through-hole 24 located at the left and right central portions of the shaft portion 21; and a pair of left and right extending portions 25 that extend at the left and right end portions of the shaft portion 21 so as to connect the front and rear portions adjacent to the press-fitting portion 23. The through-hole 24 penetrates the left and right central portions of the shaft portion 21 in the plate thickness direction (up and down direction) between the respective extending portions 25. Each extending portion 25 protrudes more outward in the left and right directions than the adjacent front and rear portions. Each extending portion 25 contacts the inner surface of the through-hole 101 of the substrate 100 and elastically deforms in a direction to reduce the left and right width of the through-hole 24.

[0031] As Figure 3 and Figure 4 shown, the press-fitting terminal 20 has a pair of left and right shoulders 26 that protrude outward in the left and right directions from the shaft portion 21 behind the press-fitting portion 23. When viewed from above ( Figure 4 the outer side in the paper thickness direction of the drawing), each shoulder 26 has a rectangular shape that is long in the front and rear directions. The front ends of the respective shoulders 26 are arranged along the left and right directions and are connected to the rear ends of the respective extending portions 25 via a curved surface portion. The rear ends of the respective shoulders 26 are also arranged along the left and right directions and are configured as pressing ends 27 that are pressed by a jig (not shown). By pressing the pressing ends 27 of the respective shoulders 26 with the jig, the press-fitting portion 23 is inserted into the through-hole 101 of the substrate 100.

[0032] As Figure 3 shown, the shaft portion 21 of the press-fitting terminal 20 has a torsion portion 28 having a shape that twists around the axis behind the respective shoulders 26. The torsion portion 28 is formed rearward from a position corresponding to the rear ends of the respective shoulders 26 in a range exceeding the front and rear length of the respective shoulders 26. The front side portion (the portion located in front of the torsion portion 28 and having the respective shoulders 26 and the press-fitting portion 23) of the press-fitting terminal 20 on both sides of the torsion portion 28 is arranged with the plate surface facing the up and down direction ( Figure 4 the paper thickness direction of the drawing), and the rear side portion (the portion located behind the torsion portion 28 and having the respective locking portions 29 described later) is arranged with the plate surface facing the left and right direction ( Figure 5 the paper thickness direction of the drawing). That is, the front and rear portions of the shaft portion 21 have plate surfaces facing different directions via the torsion portion 28.

[0033] As Figure 3 and Figure 5 shown, the press-fitting terminal 20 has a plurality of locking portions 29 behind the torsion portion 28, and the plurality of locking portions 29 protrude upward and downward from corresponding portions of the shaft portion 21. A pair of each of the locking portions 29 are formed protruding from the upper and lower edges of the shaft portion 21 respectively. As Figure 5As shown, each locking portion 29 is claw-shaped and has: a trailing edge 31 that slopes forward as it approaches the tip in the protruding direction; a leading edge 32 along the vertical direction; and a tip edge 33 of the protruding direction that extends in the front-rear direction between the leading edge 32 and the trailing edge 31. Each of the front locking portions 29 protrudes more laterally upward and downward than each of the rear locking portions 29. As Figure 2 shown, each locking portion 29 is locked to the inner surface of the locking hole 63 of the housing 60.

[0034] The shaft portion 21 of the press-fit terminal 20 has displacement allowance portions 34 at front and rear positions corresponding to (repeating) each locking portion 29. As Figure 3 and Figure 5 shown, the displacement allowance portion 34 is configured as a hole that penetrates the upper and lower central portions of the shaft portion 21 in the plate thickness direction (left-right direction). Specifically, the displacement allowance portion 34 is a long hole that is longer in the front-rear direction than in the vertical direction, and is disposed at front and rear positions that respectively overlap with the front and rear locking portions 29. As Figure 7 shown, the displacement allowance portion 34 is formed to be one size smaller than the through hole 24. The displacement allowance portion 34 allows elastic displacement of each locking portion 29 that is locked to the locking hole 63. In addition, the shaft portion 21 of the press-fit terminal 20 has a connecting portion 35 that extends in the front-rear direction with a certain vertical width between the portion inserted into the locking hole 63 of the housing 60 (the portion having each locking portion 29 and the displacement allowance portion 34) and the torsion portion 28.

[0035] (Functions of the press-fit terminal 20 and the connector 10) When manufacturing the press-fit terminal 20, first, the flat plate terminal 20A as Figure 7 shown is formed by punching a conductive metal plate. As Figure 7 shown, in the flat plate terminal 20A, each locking portion 29 and each shoulder portion 26 protrude from the shaft portion 21 in the same direction (the plate width direction), and the through hole 24 and the displacement allowance portion 34 penetrate the shaft portion 21 in the same direction (the plate thickness direction).

[0036] Next, a process of twisting 90 degrees about the axis is performed on the portion between each locking portion 29 and each shoulder portion 26 in the flat plate terminal 20A to form the torsion portion 28. As Figure 6 shown, through the torsion portion 28, each locking portion 29 and each shoulder portion 26 are misaligned about the axis so as not to overlap each other when viewed from the rear. When viewed from the rear, the pressing end 27 of each shoulder portion 26 can be visually recognized without being blocked by each locking portion 29. In this way, the press-fit terminal 20 is formed.

[0037] Next, the press-fitting portion 23 is inserted shallower from the insertion portion 64 into the through-hole 101 of the substrate 100, and a jig (not shown) is abutted against the pressing end 27 of each shoulder portion 26 from the rear. As described above, since each shoulder portion 26 and each locking portion 29 are offset around the axis, the jig can be abutted against the pressing end 27 of each shoulder portion 26 without contacting each locking portion 29. In the case of the first embodiment, the jig is simultaneously abutted against the shoulder portions 26 of a plurality of press-fitting terminals 20. In this state, the pressing end 27 of each shoulder portion 26 is pressed with the jig, and the press-fitting portion 23 is inserted (pressed) into the through-hole 101 of the substrate 100 to a regular depth. Thereby, the press-fitting terminal 20 is connected to the conductive portion of the substrate 100. In addition, the press-fitting terminal 20 is held (fixed) in a state of being restricted from moving relative to the substrate 100 by the elastic force of each extending portion 25 of the press-fitting portion 23.

[0038] Next, the housing 60 is assembled to the substrate 100 from the rear in a manner of covering the substrate 100. By the assembly of the housing 60 relative to the substrate 100, as Figure 2 shown, each locking portion 29 of the press-fitting terminal 20 is locked to the locking hole 63 of the base portion 61 in an indented manner. In the case of the first embodiment, each locking portion 29 is arranged in the locking hole 63 in a state of being elastically displaced toward the side (the axial center side of the shaft portion 21) where the opening width of the hole of the displacement allowance portion 34 is reduced. The locking force of each locking portion 29 relative to the locking hole 63 of the housing 60 is adjusted by the displacement allowance portion 34 to be smaller than the holding force of the press-fitting portion 23 relative to the through-hole 101 of the substrate 100. Therefore, when the housing 60 is assembled to the substrate 100, the situation where the press-fitting portion 23 is detached from the through-hole 101 of the substrate 100 can be avoided.

[0039] The housing 60 is fixed to the substrate 100 via a fixing member (not shown). In a state where the housing 60 is fixed to the substrate 100, as Figure 2 shown, the front portions of each shoulder portion 26, the torsion portion 28, and the connecting portion 35 are arranged between the base portion 61 of the housing 60 and the surface of the substrate 100. When a mating connector (not shown) is engaged with the cover portion 62 of the housing 60, a mating terminal (not shown) mounted on the mating connector is connected to the rear portion of the press-fitting terminal 20 (the portion protruding into the cover portion 62 behind each locking portion 29). Here, since each locking portion 29 is respectively locked to each locking hole 63 of the base portion 61, even when a fitting force acts on the press-fitting terminal 20 during the connection with the mating terminal, the relative positional change of the press-fitting terminal 20 relative to the base portion 61 can be suppressed. As a result, it is possible to prevent the press-fitting terminal 20 from tilting or the locking portions 29 and the press-fitting portion 23 from being deformed.

[0040] As described above, the press-fit terminal 20 of the present Embodiment 1 includes a shaft portion 21 extending in the front-rear direction (axial direction). The press-fit terminal 20 has: a press-fit portion 23 located at the front end portion, which can be elastically deformed in a direction orthogonal to the front-rear direction; a shoulder portion 26 located rearward of the press-fit portion 23, protruding from the shaft portion 21 in the left-right direction orthogonal to the front-rear direction; and a claw-shaped locking portion 29 located rearward of the shoulder portion 26, protruding from the shaft portion 21 in the up-down direction orthogonal to the front-rear direction. The shoulder portion 26 and the locking portion 29 are offset so as not to overlap each other when viewed from the rear.

[0041] According to the above structure, when the press-fit portion 23 is inserted (pressed) into the through hole 101 of the substrate 100 and connected thereto, the shoulder portion 26 can be pressed from the rear without obstruction by a jig (not shown). In addition, when the press-fit terminal 20 is assembled to the connector 10, the locking portion 29 can be locked to the housing 60. Therefore, when the connector 10 is engaged with the mating connector and the engagement force acts on the locking portion 29, the locking portion 29 can be prevented from tilting relative to the housing 60. As a result, it is possible to prevent the locking portions 29 and the press-fit portions 23 from being deformed by the engagement force.

[0042] In addition, the press-fit terminal 20 of the present Embodiment 1 has a torsion portion 28. The torsion portion 28 is located between the shoulder portion 26 and the locking portion 29 and is twisted around the axis so as to generate the above-mentioned offset. When manufacturing the press-fit terminal 20, the torsion portion 28 can be easily formed by performing torsion processing after blanking a conductive sheet into a predetermined shape.

[0043] In addition, in the case of the present Embodiment 1, the shaft portion 21 has a displacement allowance portion 34 at a position overlapping the locking portion 29 in the front-rear direction. The displacement allowance portion 34 allows elastic displacement of the locking portion 29. Since the shaft portion 21 has the displacement allowance portion 34 that allows elastic displacement of the locking portion 29, the displacement allowance portion 34 can be used to reduce the locking force of the locking portion 29 relative to the housing 60. While ensuring a predetermined locking force for the locking portion 29, it is possible to prevent the press-fit portion 23 from detaching from the through hole 101 of the substrate 100 during the assembly of the housing 60.

[0044] Here, since the displacement allowance portion 34 is a hole penetrating the shaft portion 21, the hole serving as the displacement allowance portion 34 can be easily formed by blanking the shaft portion 21 by stamping. Further, since a plurality of locking portions 29 are arranged in the front-rear direction (axial direction) of the shaft portion 21 and the displacement allowance portion 34 is a long hole that is long in the front-rear direction, the displacement allowance portion 34 can allow elastic displacement of each of the plurality of locking portions 29 arranged in the front-rear direction.

[0045] The connector 10 of the present Embodiment 1 includes a housing 60 in which press - fit terminals 20 are mounted. The press - fit portion 23 is connected to the through - hole 101 of the substrate 100, and a locking hole 63 for locking with the locking portion 29 is formed in the housing 60. By pressing the shoulder portion 26 with a jig without being obstructed by the locking portion 29, the press - fit portion 23 can be inserted into the through - hole 101 of the substrate 100 and connected thereto. Then, by locking the locking portion 29 with the locking hole 63 of the housing 60, the relative positional displacement between the press - fit terminal 20 and the housing 60 can be suppressed, and it is possible to prevent the press - fit terminal 20 from tilting or deforming when the connector 10 is engaged.

[0046] [Other Embodiments of the Present Invention] It should be considered that the above - described Embodiment 1 of the present disclosure is illustrative rather than restrictive in all respects. In the case of the above - described Embodiment 1, it is configured such that when the housing is fixed to the substrate via legs, the locking portion of the press - fit terminal locks with the housing. In contrast, according to other embodiments, it may also be configured such that the housing and the upper housing are provided integrally, the substrate is housed in the lower housing, and when the upper housing is fixed to the lower housing, the locking portion of the press - fit terminal locks with the housing. In the case of the above - described Embodiment 1, the shaft portion is formed to extend over the entire length of the press - fit terminal in the front - rear direction. In contrast, according to other embodiments, a shaft portion extending in the front - rear direction (axial direction) may also be formed on a part of the press - fit terminal. For example, the rear portion of the press - fit terminal may also include a portion bent from the shaft portion in a direction crossing (including orthogonal) the axial direction. In the case of the above - described Embodiment 1, the displacement - allowing portion is configured as a hole (including a long hole). In contrast, according to other embodiments, the displacement - allowing portion may have any shape that can be elastically deformed. For example, instead of penetrating the shaft portion, a part of the shaft portion may be formed as a thin wall so that it can be elastically deformed. In the case of the above - described Embodiment 1, the shoulder portion and the locking portion are configured to be displaced so as not to overlap each other when viewed from the rear by means of the torsion portion. In contrast, according to other embodiments, the shoulder portion and the locking portion may also be configured to be displaced so as not to overlap each other when viewed from the rear by being integrally formed during die - forming.
