Description

Technical Field

[0001] The present invention relates to a rod type connector. Background Art

[0002] As a connector capable of detecting mating, a connector described in Japanese Patent Publication No. 2015-50036 (hereinafter referred to as Patent Document 1) is known in the past. The connector comprises: a housing capable of mating with a mating connector; a mating rod supported by the housing; a housing locking member that locks the mating rod when mating with the mating connector is completed; and a mating detection terminal that forms a detection circuit by contacting the mating detection terminal of the mating connector. When the rotation operation of the mating rod starts, the action block provided on the mating rod causes the housing locking member to bend, and the mating detection terminal is pressed by the housing locking member and deformed. Thus, the mating detection terminal is arranged in a position separated from the mating detection terminal of the mating connector before the mating rod reaches the mating completion position. When the mating rod reaches the mating completion position, the engagement between the action block and the housing locking member is released, and the housing locking member returns to a natural state. Thus, the mating detection terminal is intended to recover from the flexed and deformed state and contact the mating detection terminal of the mating connector.

[0008] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples.

[0009] (1) The rod-type connector of the present invention can be mated with a connector on the other side having a detection terminal on the other side, and the rod-type connector comprises: a shell; a rod that can be rotatably installed on the shell between a mating start position and a mating completion position; and a detection terminal that is held in the shell and forms a detection circuit by contacting the detection terminal on the other side, the shell having a flexure that is opposite to the detection terminal and can bend and deform, the rod having a first pressing portion and a second pressing portion, the first pressing portion and the second pressing portion press the flexure toward the detection terminal to separate the detection terminal from the detection terminal on the other side, and during the process of the rod rotating from the mating start position to the mating completion position, the first pressing portion starts to press the flexure before the second pressing portion, and when the rod reaches the mating completion position, the pressure of the second pressing portion on the flexure is released, and the detection terminal contacts the detection terminal on the other side.

[0010] According to such a configuration, the first pressing portion and the second pressing portion that presses the flexible piece behind the first pressing portion press the flexible piece toward the detection terminal, so that the rotation angle range of the lever in a state where the detection terminal is pressed can be easily increased.

[0011] (2) Preferably, during the process of the rod rotating from the mating start position toward the mating completion position, when the second pressing portion starts to press the flexible piece, the flexible piece is in a state of being pressed by the first pressing portion, and when the flexible piece is in a state of being pressed by the second pressing portion, the first pressing portion leaves the flexible piece.

[0012] According to such a configuration, when the second pressing portion starts pressing the flexible piece and when the first pressing portion moves away from the flexible piece, it is possible to suppress a large change in the amount of deflection of the flexible piece.

[0013] (3) Preferably, the flexible piece is a lock arm, and the second pressing portion has a locking portion, and the locking portion is locked with the lock arm when the lever is located at the mating completion position.

[0014] According to such a structure, it is not necessary to separately provide the bending piece and the locking arm, and it is also not necessary to separately provide the second pressing portion and the locking portion. Therefore, the structure of the lever-type connector can be simplified.

[0015] (4) Preferably, the second pressing portion has a sliding contact portion that is curved and can slide in contact with the flexible piece.

[0016] According to such a configuration, it is easy to make the deflection amount of the deflection piece in the state of being pressed by the second pressing portion constant.

[0017] [Details of Embodiments of the Invention] The following will describe embodiments of the present invention. The present invention is not limited to these examples but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0018] <Implementation Method> Reference Figures 1 to 15 The embodiment of the present invention is described. In the following description, the direction indicated by the arrow line Z is regarded as the upward direction, the direction indicated by the arrow line X is regarded as the front direction, and the direction indicated by the arrow line Y is regarded as the left direction. In addition, with respect to a plurality of identical components, sometimes only some of the components are marked with reference numerals, and the reference numerals of the other components are omitted. Figure 1 As shown, the mating connector 50 that the lever-type connector 10 can be mated with is a substrate connector mounted on a circuit substrate (not shown). In this embodiment, three lever-type connectors 10 can be mated with one mating connector 50. In the drawings, only the lever-type connector 10 that is mated with the central portion of the mating connector 50 is shown.

[0019] [Mate side connector] The counterpart connector 50 includes a counterpart housing 51, a plurality of counterpart terminals 52 and a plurality of counterpart detection terminals 53 held in the counterpart housing 51. The counterpart housing 51 is made of synthetic resin and has a rectangular shape that is long in the horizontal direction as a whole. Figure 1 and Figure 2 As shown, the mating housing 51 includes a plurality of fitting recesses 54, and the lever-type connector 10 can be fitted inside the plurality of fitting recesses 54. A pair of cam pins 55 are provided on both side walls 54A constituting the left and right sides of the fitting recess 54. The pair of cam pins 55 are provided one on each side wall 54A and are arranged symmetrically. The cam pins 55 are formed in a cylindrical shape.

[0020] like Figure 5 As shown, the other-side terminal 52 and the other-side detection terminal 53 are composed of metal needle terminals, and are held on the inner wall 54B in a manner that penetrates the inner wall 54B that constitutes the mating recess 54 in the front-to-back direction. One end of the other-side terminal 52 and the other-side detection terminal 53 protrudes from the inner wall 54B into the mating recess 54 and extends in the front-to-back direction. The other ends of the other-side terminal 52 and the other-side detection terminal 53 are arranged outside the mating recess 54 and are bent downward. The other-side detection terminal 53 is electrically connected to the detection terminal 30 provided on the rod-type connector 10 when the other-side connector 50 and the rod-type connector 10 are properly mated (refer to Fig.14 ).

[0021] Figure 7 This is a cross-sectional view, so only one detection terminal 53 on the other side is shown, but Figure 1 and Figure 2 As shown, the counterpart housing 51 holds two counterpart detection terminals 53 spaced apart in the width direction in one fitting recess 54. The two counterpart detection terminals 53 are connected to a detection device. The two counterpart detection terminals 53 cannot be connected to each other before the detection terminals 30 of the lever-type connector 10 come into contact with each other, but a detection circuit is formed when the detection terminals 30 and the two counterpart detection terminals 53 come into contact with each other.

[0022] [Lever type connector] like Figure 1 As shown, the lever-type connector 10 includes a housing 20, a plurality of terminals (not shown), a detection terminal 30 (see Figure 7 ) and rod 40. The terminal is a female terminal and is connected to the other side terminal 52. The rod 40 can Figure 5 The chimera start position shown is Figure 6 When the lever 40 moves from the mating start position to the mating completion position, the lever-type connector 10 is mated toward the mating connector 50, and when it moves from the mating completion position to the mating start position, the lever-type connector 10 is separated from the mating connector 50.

[0023] [case] The housing 20 is made of synthetic resin, such as Figure 2 As shown in FIG. 2 , the housing 20 is formed into a substantially square block shape. A terminal receiving portion 21 is provided through the housing 20 in the front-to-back direction, and the terminal receiving portion 21 receives the terminal. Figure 7 As shown, a detection terminal receiving portion 22 is provided through the housing 20 in the front-rear direction, and the detection terminal receiving portion 22 receives the detection terminal 30. The detection terminal receiving portion 22 is arranged on the upper side of the housing 20 and in the center in the left-right direction.

[0024] [Flexible sheet] like Figure 8 As shown in FIG. 1 , the housing 20 includes a flexure piece 23 extending rearward from the upper wall of the housing 20. The flexure piece 23 is configured to be able to bend and deform in the vertical direction with the front end connected to the upper wall of the housing 20 as the base end. The flexure piece 23 of this embodiment is a locking arm. The flexure piece 23 includes a flexure piece body 23A and a fitting locking portion 23B protruding upward from the rear of the flexure piece body 23A. Figure 3 and Figure 4 As shown, in the present embodiment, two engaging locking portions 23B are provided at intervals in the left-right direction on the flexure piece 23. When the lever-type connector 10 and the mating connector 50 are properly engaged, the engaging locking portion 23B is locked with the locking portion 45B provided on the lever 40 (see FIG. Fig.15 ).

[0025] like Figure 8 As shown, the upper surface of the fitting lock portion 23B is a sliding contact portion 24, and the sliding contact portion 24 is a curved surface with a convex shape upward. A pressing start portion 25 with a rounded shape is provided on the upper side of the rear end portion of the flexible piece 23.

[0026] The flexible piece 23 is arranged to partition the upper part of the detection terminal storage part 22. The flexible piece 23 is provided with a protrusion 23C protruding from the flexible piece body 23A toward the inside of the detection terminal storage part 22. The protrusion 23C presses the detection terminal 30 when the flexible piece 23 is deformed downward.

[0027] [Detection terminal] The detection terminal 30 is formed by bending a conductive metal plate into a predetermined shape, etc., and includes: a substrate portion 31 arranged along the inner surface of the lower side of the detection terminal storage portion 22; and a spring portion 32 folded back from the rear end of the substrate portion 31 toward the front and bent into a predetermined shape. The spring portion 32 includes: a contact portion 33 arranged near the front end of the spring portion 32; and a snap-fit ​​portion 34 arranged at the rear of the spring portion 32. The contact portion 33 and the snap-fit ​​portion 34 are bent in a mountain-shaped manner protruding upward. The spring portion 32 is divided into two branches on the top side (front end side), and a pair of left and right contact portions 33 are provided.

[0028] like Fig.14 As shown, when the lever-type connector 10 and the mating connector 50 are properly mated, each contact portion 33 contacts the mating detection terminal 53. Thus, the two mating detection terminals 53 and the detection terminal 30 are electrically connected to form a detection circuit.

[0029] like Fig. 9 As shown, the engagement portion 34 is pressed by the protrusion 23C of the flexible piece 23. As the engagement portion 34 is pressed by the protrusion 23C, the contact portion 33 is displaced so as to approach the substrate portion 31.

[0030] like Figure 5 and Figure 6 As shown, a pair of rotation shafts 26 protruding outward from the housing 20 in the left-right direction are provided on both side surfaces of the housing 20. The pair of rotation shafts 26 are provided one on each side surface and are arranged symmetrically.

[0031] [Pole] The lever 40 is rotatably supported by the housing 20, and is operated when the lever-type connector 10 is mated with the mating connector 50 and when the mating is released, thereby functioning as a force-increasing mechanism. Figure 5 The starting position of the chimera is shown to Figure 6 That is, when the lever 40 is rotated counterclockwise from the mating start position to the mating completion position, the lever-type connector 10 and the mating connector 50 are properly mated.

[0032] The rod 40 is made of synthetic resin. Figure 3 and Figure 4 As shown, the lever 40 includes a pair of cam plates 41 and an operating portion 42 that connects the distal ends of the pair of cam plates 41 to each other, and is gate-shaped as a whole.

[0033] like Figure 5 and Figure 6 As shown, each cam plate 41 is formed with a shaft hole 41A penetrating the cam plate 41. The rotation shaft 26 is inserted into the shaft hole 41A. The lever 40 is supported by the housing 20 so as to be rotatable around the rotation shaft 26.

[0034] The cam plate 41 has a track 43 into which the cam pin 55 enters. The track 43 has an inlet 43A that opens forward at the outer edge of the cam plate 41, and is formed so as to approach the shaft hole 41A as it moves from the inlet 43A toward the terminal 43B. When the lever 40 is at the mating start position, if the lever-type connector 10 and the mating connector 50 are shallowly mated, Figure 5 As shown, the cam pin 55 enters the inlet 43A of the track 43.

[0035] When the lever 40 is moved from the mating start position to the mating completion position, the cam pin 55 engages with the inner wall of the rail 43, thereby mating the lever-type connector 10 and the mating connector 50. Figure 6 As shown, the cam pin 55 is located at the terminal end 43B of the rail 43. On the contrary, when the lever 40 is moved from the mating completion position to the mating start position, the cam pin 55 engages with the inner wall of the rail 43, thereby separating the lever-type connector 10 and the mating connector 50.

[0036] [First pressing portion, second pressing portion] like Figure 8 As shown, the lever 40 includes a second pressing portion 45 protruding from the operating portion 42 toward the inner side of the rotational radial direction, and a first pressing portion 44 protruding from the second pressing portion 45 toward the inner side of the rotational radial direction. Here, the rotational radial direction refers to the axis extending direction that is orthogonal to the extending direction (left-right direction) of the rotational axis 26 and passes through the rotational center, with the direction approaching the rotational axis 26 being the inner side and the direction away from the rotational axis 26 being the outer side. Figure 4 As shown, the second pressing portion 45 is disposed at the left-right center of the operation portion 42. The first pressing portion 44 is smaller than the second pressing portion 45 in the left-right direction and is disposed at the left-right center of the second pressing portion 45.

[0037] [Sliding part, locking part] like Fig.11 As shown in FIG. 1 , the second pressing portion 45 includes a sliding portion 45A having a curved surface. The sliding portion 45A has an arc shape when viewed from the side, and the arc shape is a portion of a circle approximately centered on the rotation shaft 26. Fig.15 As shown in the figure, the rear end surface of the second pressing portion 45 is the locking portion 45B, with the lever 40 being located at the mating completion position as a reference. When the lever-type connector 10 and the mating connector 50 are properly mated, the locking portion 45B is arranged opposite to the mating lock portion 23B, and the locking portion 45B and the mating lock portion 23B are locked, thereby restricting the lever 40 from rotating in the direction of releasing the mating.

[0038] The first pressing portion 44 protrudes from the sliding portion 45A in a mountain shape. That is, the first pressing portion 44 is provided at the front side portion of the sliding portion 45A with the lever 40 being located at the mating completion position as a reference.

[0039] [Pressing of the Flexing Piece by the First Pressing Part and the Second Pressing Part] Next, a description will be given of a process in which the first pressing portion 44 and the second pressing portion 45 press the flexible piece 23 when the lever-type connector 10 is mated with the mating connector 50 .

[0040] The lever-type connector 10 is positioned relative to the mating connector 50, and the housing 20 is inserted into the fitting recess 54 (see Figure 1 and Figure 5 ). In the stage before the shallow insertion operation begins, such as Figure 7 and Figure 8 As shown, since the rod 40 is separated from the flexure piece 23, the flexure piece 23 and the detection terminal 30 are in a natural state. In addition, the detection terminal 30 and the counterpart detection terminal 53 are separated in the fitting direction (front-rear direction).

[0041] When the cam pin 55 enters the entrance 43A of the rail 43, the operation portion 42 is operated, and the lever 40 rotates from the fitting start position toward the fitting completion position. Fig. 9 As shown, first, the first pressing portion 44 of the rod 40 contacts the pressing start portion 25 of the flexure piece 23. As a result, the flexure piece 23 is bent and deformed downward. Furthermore, the protrusion 23C of the flexure piece 23 presses the engaging portion 34 of the detection terminal 30, causing the spring portion 32 to bend and deform downward.

[0042] Further, when the rod 40 rotates, as shown in FIG. Fig.10 As shown in FIG. 1 , the first pressing portion 44 enters the gap between the two interlocking locking portions 23B while pressing the flexure piece 23. Fig.11 As shown in FIG. 1 , the sliding portion 45A of the second pressing portion 45 begins to slide with the slidably contacted portion 24 of the interlocking locking portion 23B. When the lever 40 is further rotated, the sliding portion 45A slides with the slidably contacted portion 24 (see FIG. 1 ). Fig.13 ), the first pressing portion 44 leaves the flexure piece 23 (refer to Fig.12 ).

[0043] In addition, from Figure 10 to Figure 12 During the process of the state of the detection terminal 53 on the other side, the top end portion of the detection terminal 53 on the other side reaches a position overlapping with the detection terminal 30 in the front-back direction. However, since the spring portion 32 is pressed by the protrusion 23C of the flexure 23, the contact portion 33 is pressed down to a position lower than the detection terminal 53 on the other side, so the detection terminal 30 and the detection terminal 53 on the other side do not contact.

[0044] As described above, in this embodiment, within a predetermined rotation angle range, both the first pressing portion 44 and the second pressing portion 45 press the flexible piece 23 (see Fig.11 Thus, when the second pressing portion 45 contacts the flexible piece 23 and the pressing of the flexible piece 23 by the first pressing portion 44 is released, it is easy to suppress a large change in the amount of bending of the flexible piece 23.

[0045] Furthermore, when the lever 40 rotates, the lever-type connector 10 and the mating connector 50 are mated with each other while the sliding portion 45A and the slidably contacted portion 24 are in sliding contact. Here, since the sliding portion 45A and the slidably contacted portion 24 are curved, the deflection amount of the deflection piece 23 is easily maintained substantially constant.

[0046] When the rod 40 reaches the mating completion position, Fig.15 As shown, the sliding contact between the sliding contact portion 45A and the slidably contacted portion 24 is released, and the flexure piece 23 returns to its natural state. As a result, the locking portion 45B of the second pressing portion 45 and the interlocking locking portion 23B of the flexure piece 23 can be configured to be interlocked. The locking portion 45B and the interlocking locking portion 23B are interlocked, so that the rod 40 can be prevented from rotating from the interlocking completion position to the interlocking start position. In addition, as shown in FIG. Fig.14 As shown, along with the elastic restoration of the flexure 23, the spring portion 32 also tends to elastically restore to the original position, and the contact portion 33 contacts the other-side detection terminal 53. In this way, a detection circuit is formed by the detection terminal 30 and the other-side detection terminal 53, so through the conduction between the two, it can be recognized that the other-side connector 50 and the lever-type connector 10 are properly mated.

[0047] As described above, in this embodiment, since the first pressing portion 44 and the second pressing portion 45 are provided, even if the first pressing portion 44 reaches a rotation angle away from the flexure piece 23, the rod 40 can be rotated while the second pressing portion 45 continues to press the flexure piece 23. Therefore, compared with the case where only one pressing portion is provided, the flexure piece 23 can be continuously pressed within a wide rotation angle range. Therefore, the lever-type connector 10 and the counterpart connector 50 can be mated within a large rotation angle range, so it is easy to ensure the effective contact amount between the detection terminal 30 and the counterpart detection terminal 53. In addition, it is easy to obtain the effect of reducing the mating force of the rod 40.

[0048] [Effects of the Embodiments] According to the implementation mode, the following actions and effects are achieved. The lever-type connector 10 of the embodiment is a lever-type connector 10 that can be mated with a mating-side connector 50 having a mating-side detection terminal 53, and comprises: a housing 20; a lever 40 that can be rotatably mounted on the housing 20 between a mating start position and a mating completion position; and a detection terminal 30 that is held in the housing 20 and forms a detection circuit by contacting the mating-side detection terminal 53. The housing 20 comprises a flexure 23 that is opposite to the detection terminal 30 and can be flexibly deformed, and the lever 40 comprises a first pressing portion 44 and a second pressing portion 45. The first pressing portion 44 and the second pressing portion 45 press the flexible piece 23 toward the detection terminal 30, thereby separating the detection terminal 30 from the detection terminal 53 on the other side. In the process of the rod 40 rotating from the mating start position to the mating completion position, the first pressing portion 44 starts to press the flexible piece 23 before the second pressing portion 45. When the rod 40 reaches the mating completion position, the second pressing portion 45 releases the pressing of the flexible piece 23, and the detection terminal 30 contacts the detection terminal 53 on the other side.

[0049] According to such a structure, the flexible piece 23 is pressed toward the detection terminal 30 by the first pressing portion 44 and the second pressing portion 45 pressing the flexible piece 23 behind the first pressing portion 44, so it is easy to increase the rotation angle range of the rod 40 in the state where the detection terminal 30 is pressed.

[0050] In an embodiment, during the process of the rod 40 rotating from the mating start position toward the mating completion position, when the second pressing portion 45 starts to press the flexible piece 23, the flexible piece 23 is in a state of being pressed by the first pressing portion 44. When the flexible piece 23 is pressed by the second pressing portion 45, the first pressing portion 44 leaves the flexible piece 23.

[0051] According to such a configuration, when the second pressing portion 45 starts pressing the flexible piece 23 and when the first pressing portion 44 moves away from the flexible piece 23 , it is possible to suppress a large change in the amount of deflection of the flexible piece 23 .

[0052] In the embodiment, the flexible piece 23 is a lock arm, and the second pressing portion 45 has a locking portion 45B. When the lever 40 is located at the mating completion position, the locking portion 45B is locked with the lock arm.

[0053] According to such a structure, the flexible piece 23 and the lock arm do not need to be provided separately, and the second pressing portion 45 and the locking portion 45B do not need to be provided separately. Therefore, the structure of the lever-type connector 10 can be simplified.

[0054] In the embodiment, the second pressing portion 45 has a sliding contact portion 45A that has a curved surface and can slide in contact with the flexible piece 23 .

[0055] According to such a configuration, it is easy to make the deflection amount of the deflection piece 23 in the state pressed by the second pressing portion 45 constant.

[0056] <Other Implementation Methods> (1) In the above embodiment, the mating connector 50 includes three fitting recesses 54 , but the present invention is not limited thereto. The number of fitting recesses of the mating connector may be one, two, or four or more. (2) In the above embodiment, the first pressing portion 44 is configured to protrude from the second pressing portion 45, but the present invention is not limited thereto. The first pressing portion and the second pressing portion may not be continuously disposed, and the relative arrangement of the first pressing portion and the second pressing portion may be appropriately changed. (3) In the above embodiment, the lock arm is configured to include two fitting lock portions 23B, but the present invention is not limited thereto. For example, the fitting lock portion may be one. (4) In the above-mentioned embodiment, the first pressing portion 44 and the second pressing portion 45 are configured to press the flexure piece 23 within a predetermined rotation angle range, but the present invention is not limited thereto. For example, the second pressing portion may also be configured to press the flexure piece after the first pressing portion leaves the flexure piece during the process of the rod moving from the mating start position toward the mating completion position. In this case, it is preferably configured that the flexure piece does not completely return to its natural state from the time the first pressing portion leaves the flexure piece until the time the second pressing portion starts pressing the flexure piece.
