Further, the cam portion 64 is provided with a first surface 64e that abuts against the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the rod mounting portion 35) when the lever 60 is fully opened; and When the lever 60 is in the fully closed state, the lever 60 abuts against the second surface 64f of the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the lever mounting portion 35). Further, the angle θ (see FIG. 7) formed by the first surface 64e and the second surface 64f is an acute angle. Furthermore, in the present embodiment, the angle θ formed by the first surface 64e and the second surface 64f is set to be about 77 degrees. Further, between the first surface 64e and the second surface 64f, the rotation receiving surface 64c of the above-described cam portion 64 is provided, and the rotation receiving surface 64c forms an arcuate surface which is a small radius of curvature. Further, in the present embodiment, the radius of curvature of the rotation receiving surface 64c is set to be about 0.05 mm.

Further, in the present embodiment, when the lever 60 is at the open position, the cam portion 64 is formed to be elongated in the lateral direction (the front-rear direction X) as shown in FIG. 6, and the dimension in the vertical direction Z is formed to be larger than the joint 40. The distance between the spring portion 47 and the terminal arm portion 45 and the distance between the spring portion 57 and the support arm 55 are smaller. That is, when the lever 60 is in the open position, the cam portion 64 and the spring portions 47, 57 are formed in a non-contact state.

Further, when the lever 60 is rotated in the closing direction (the direction of the arrow A in Fig. 7), the dimension of the cam portion 64 in the up-and-down direction Z is formed to be larger than the spring portion 47 and the terminal arm in the middle of the rotation of the cam portion 64. The spacing of the portions 45 and the spacing of the spring portions 57 from the support arms 55 are greater.

That is, when the lever 60 is rotated in the closing direction, the cam portion 64 is rotated by the rotation receiving surface 64c as a pivot point with the rotation of the lever 60. Further, in the middle of the rotation of the lever 60 in the closing direction, the abutting surface 64d abuts against the cam faces 47a and 57a of the spring portions 47 and 57, and is in sliding contact with the cam faces 47a and 57a. When the lever 60 is rotated in the closing direction, the cam portion 64 rotates the abutting surface 64d while being slidably attached to the cam faces 47a and 57a, and the spring portions 47 and 57 are elastically flexibly deformed so that the front end of the spring portion 47 is bent. The distance from the front end of the terminal arm portion 45 and the interval between the spring portion 57 and the support arm 55 open. Further, the joint spring portions 43 and 53 are elastically flexibly deformed by the deflection deformation of the spring portions 47 and 57, and the joint 40 is elastically flexed to form the movable side contact portion 46 of the movable side joint portion 42 and the fixed side joint. The interval between the fixed-side contact portions 44 of the portion 41 is reduced, and the distance between the movable-side holding arms 56 of the fixed-side holding portions 51 and the fixed-side holding arms 54 of the fixed-side holding portions 51 is reduced as the holding terminal 50 is elastically bent. Thereby, the movable side contact portion 46a moves in the direction of the fixed side contact portion 44a, and the movable side contact portion 46a and the fixed side contact portion 44a are pressed against the cable 2, and the cable 2 and the joint 40 are Turn on the connection. Further, the movable side engagement projection 56a moves in the direction of the fixed side engagement projection 54a, and the cable 2 is held by the holding terminal 50.

Thus, the cam portion 64 attaches a pressing force for crimping the joint 40 to the cable 2 to the joint 40 and attaching a pressing force for holding the cable 2 to the holding terminal 50.

Further, in the present embodiment, when the lever 60 is rotated in the closing direction from the open position to the closed position, the height of the cam portion 64 gradually increases until the middle of the stroke, but when the predetermined amount of rotation is exceeded, the cam portion 64 is used. The height will gradually become lower. Further, since the cam portion 64 is pressed by the elastic restoring force of the spring portions 47, 57, the direction of action of the moment acting on the lever 60 changes from the opening direction to the closing direction while the lever 60 is rotated from the open position to the closed position. .

As described above, during the rotation of the lever 60, the pressing sensation is given to the operation of the lever 60 by reducing the radius of rotation of the cam portion 64 or changing the acting direction of the moment acting on the lever 60 from the opening direction to the closing direction.

In the present embodiment, as described above, the rotation receiving surface (rotation receiving portion) 64c of the cam portion 64 is formed so as to abut against the bottom surface 37d of the vertical wall portion 37 in the open state of the rod 60 (the rod mounting portion 35) The angle θ formed by the first surface 64e of the bottom wall portion and the second surface 64f of the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the rod mounting portion 35) in the closed state of the rod 60 is formed as Sharp angle. Therefore, the width of the cam portion 64 can be narrowed to be narrower, and the rod 60 can be more easily rotated. As described above, when the lever 60 is easily rotated, when the direction of action of the moment acting on the lever 60 exceeds a predetermined amount of rotation from the opening direction to the closing direction, the lever 60 can be quickly rotated in the closing direction. The feeling of pressing of the lever operation can be increased.

Further, by forming the rotation receiving surface (rotation receiving portion) 64c in an arc shape in which the first surface 64e and the second surface 64f are joined, the rod operation can be performed more smoothly, and the rotation receiving surface due to the lever operation can be suppressed ( The rotation receiving portion 64c is cut.

Further, when the self-closing direction is rotated toward the opening direction, the same feeling of pressing can be imparted.

Further, in the circular portion 64a of the cam portion 64, as shown in Figs. 6 and 11, the engagement recesses (the uneven portions that are engaged with each other) that are engaged with the engagement projections 47d and 57d are formed as shown in Figs. ) 64g. The engaging recessed portion 64g is a side surface 64h that can abut against the front end faces 47b and 57b of the engaging projections 47d and 57d, and an arcuate surface 64i that can abut against the horizontal faces 47c and 57c of the engaging projections 47d and 57d. Formed. Moreover, the front end surfaces 47b and 57b are in contact with the side surface 64h, and the horizontal surfaces 47c and 57c are in contact with the circular arc surface 64i, and the engagement projections 47d and 57d and the engagement recessed portion 64g are engaged with each other (see FIG. 12).

In other words, in the present embodiment, the distal end faces 47b and 57b of the engaging projections 47d and 57d restrict the lever 60 from moving forward, and the horizontal faces 47c and 57c of the engaging projections 47d and 57d restrict the lever 60 from moving upward. Further, the front end surfaces 47b and 57b and the side surface 64h and the horizontal surfaces 47c and 57c and the circular arc surface 64i may be formed in surface contact with each other. Thereby, the engagement accuracy of the engagement projections 47d and 57d and the engagement recess 64g can be further improved.

Further, in the present embodiment, the spring portions 47 and 57 and the cam portion 64 are provided with concave-convex portions (engagement projections 47d and 57d and engagement recesses 64g) that are engaged with each other. However, the engagement projections 47d and 57d are provided. The engagement recessed portion 64g does not engage with each other during the opening and closing operation of the normal lever 60 (see FIG. 6).

Further, when the lever 60 is opened and closed, the non-use state (the state in which the cable 2 is not inserted), or the like, the load toward the front is applied to the lever 60 in the open state, and the lever 60 is moved forward and upward in the open state. (When the rod 60 is relatively moved in the direction in which the joint 40 is disengaged), when the protrusions 45b and 55b are slightly beyond the mountain shape, the engaging projections 47d and 57d are engaged with the engaging recessed portion 64g to suppress the rod 60 from being self-engaged. The case where the casing 30 is detached is generated (refer to FIGS. 11 and 12).

In this way, the restraining lever 60 is detached from the housing 30 in the state of being engaged, but the lever 60 is locked by the excessive load when the lever 60 is relatively moved in the disengaging direction, and the detachment preventing effect of the lever 60 can be improved not only reliably. The non-simple locking is achieved by the uneven portion (the engaging projection 47d and the engaging recess 64g), and the lever 60 can be further prevented from being detached from the housing 30.

Further, when the load toward the front is applied to the lever 60 in the open state, the front end surface 47b of the engaging projection 47d and the side surface 64h of the engaging recess 64g restrict the lever 60 from moving forward, and by the horizontal surface 47c and the circle The curved surface 64i moves the restriction lever upward, whereby the detachment prevention effect of the lever 60 can be further improved.

Mounting of the rod 60 of the structure toward the housing 30 is performed in the following manner.

First, the front ends of the spring portions 47, 57 are inserted into the through holes 63 of the rod 60, and between the front end of the spring portion 47 and the front end of the terminal arm portion 45 and between the front end of the spring portion 57 and the front end of the support arm 55. That is, the cam portion 64 is inserted between the horizontal surface 47c and the protruding portion 45b and between the horizontal surface 57c and the protruding portion 55b.

Then, the pivot shaft 61 at both ends in the width direction Y of the rod 60 is placed on the bearing portion 35a at both ends in the width direction Y of the casing 30 and the holding fastener 70 is attached to the joint wall portion 34f, whereby the rod 60 can be opened and closed. The rod mounting portion 35 of the housing 30 is attached (rotated).

Further, in the present embodiment, when the lever 60 is in the open position, the cam portion 64 is elongated in the lateral direction (the front-rear direction X) so that the front ends of the spring portions 47, 57 are inserted through the through holes 63. In other words, when the through hole 63 is opposed to the distal ends of the spring portions 47 and 57, the thickness of the cam portion 64 that faces between the horizontal surfaces 47c and 57c and the protruding portions 45b and 55b becomes small. Therefore, when the cam portion 64 is inserted between the horizontal surfaces 47c and 57c and the projections 45b and 55b, it is not necessary to press it with a large force, and the cam portion 64 can be easily inserted.

Next, the operation of the joint 40 and the holding terminal 50 when the lever 60 is temporarily closed will be described with reference to Figs. 6 to 10 .

First, when the lever 60 is in the open position, as shown in FIG. 6, the spring portion 47 of the movable side joint portion 42 approaches the top wall portion 32 of the casing 30, but does not come into contact with the top wall portion 32. In other words, the spring portion 47 and the top wall portion 32 of the movable side joint portion 42 are formed in a state of being separated by a gap. At this time, the cam portion 64 of the lever 60 and the cam surface 47a of the spring portion 47 are formed in a non-engaged state. Further, although not shown, the spring portion 57 of the movable-side holding portion 52 is also formed in the same state. In other words, the spring portion 57 of the movable-side holding portion 52 and the top wall portion 32 are formed to have a gap and are separated, and the cam portion 64 of the lever 60 and the cam surface 57a of the spring portion 57 are formed in a non-engaged state.

Next, the cable 2 is inserted into the casing 30. At this time, the distance D2 between the fixed side contact portion (front end) 44a of the fixed side contact portion 44 of the joint 40 and the movable side contact portion (front end) 46a of the movable side contact portion 46 is substantially the same as the thickness of the cable 2. Therefore, it is possible to suppress the occurrence of friction between the cable 2 and the joint 40, and the cable 2 can be smoothly inserted into the casing 30. Further, since the distance between the fixed-side engagement projection 54a of the holding terminal 50 and the movable-side engagement projection 56a (the distance between the pair of engagement projections) D1 is smaller than the thickness of the cable 2, when the cable 2 is to be used When inserted into the casing 30, the fixed side engagement projection 54a and the movable side engagement projection 56a are inserted into the holding hole 2c from the surface of the cable 2. Thereby, the cable 2 is temporarily held by holding the terminal 50. Therefore, even if the lever 60 is in the open position, the cable 2 can be prevented from being detached. Further, in the present embodiment, by providing one holding terminal 50 at each end in the width direction Y of the joint 40, it is possible to suppress the increase in the frictional force generated between the cable 2 and the holding terminal 50 as much as possible. It is strongly suppressed that the cable 2 is prevented from being obstructed by the holding terminal 50 in the smooth insertion operation in the casing 30.

Further, when the rod 60 is rotated in the clockwise direction indicated by the arrow A in a state where the cable 2 has been inserted into the casing 30, the joint abutting surface 64d abuts against the spring portion as shown in FIG. The cam surface 47a of the slider 47 is slidably coupled to the cam surface 47a. When the lever 60 is rotated in the closing direction, the cam portion 64 rotates while the joint abutting surface 64d is in sliding contact with the cam surface 47a, and the spring portion 47 is elastically flexed to form the front end of the spring portion 47 of the joint 40. It is opened opposite to the interval of the front end of the terminal arm portion 45. Further, in the middle of the rotation of the rod 60 in the closing direction, the slightly intermediate portion of the spring portion 47 comes into contact with the top wall portion 32. Further, the same operation is performed on the holding terminal 50, and the middle portion of the spring portion 57 after the deflection is brought into contact with the top wall portion 32 while the rod 60 is rotated in the closing direction.

Then, the connecting spring portion 43 is elastically flexibly deformed in accordance with the deflection deformation of the spring portion 47. By bending the spring portion 47 and the connecting spring portion 43, the joint 40 is elastically flexed to form a space between the movable side contact portion 46 of the movable side joint portion 42 and the fixed side contact portion 44 of the fixed side joint portion 41. (The distance between the movable side contact portion 46a and the fixed side contact portion 44a) becomes small. In other words, the movable side contact portion 46a moves in the direction of the fixed side contact portion 44a. As a result, the cable 2 is electrically connected to the joint 40 in a state where the movable side contact portion 46a is pressed against the fixed side contact portion 44a.

At this time, when the terminal 50 is held, as shown in FIG. 10, when the spring portion 57 and the connecting spring portion 53 are deflected, the movable side holding arm 56 elastically deformed to form the movable side holding portion 52 is held by the fixed side. The interval between the fixed-side holding arms 54 of the portion 51 (the distance D1 between the movable-side engaging projections 56a and the fixed-side engaging projections 54a) becomes small. As a result, the movable side engagement projection 56a and the fixed side engagement projection 54a are further inserted into the holding hole 2c from the front surface side of the cable 2. In other words, the engagement accuracy between the movable-side engagement projection 56a and the fixed-side engagement projection 54a and the holding hole 2c can be further increased, and the holding terminal 50 can stably hold the cable 2. In this embodiment, the movable side engagement projection 56a and the fixed side engagement projection 54a are inserted into the holding hole 2c from both sides of the surface of the cable 2, so that the holding terminal 50 holds the cable 2, and therefore even In the case where the thickness of the cable 2 is uneven or an external force acts on the cable 2, the cable 2 is not easily detached. That is, in the present embodiment, it is possible to suppress the cable 2 from being detached from the connector 1.

As described above, in the present embodiment, the shape of the holding terminal 50 is substantially the same as the shape of the joint 40, and the rotation of the rod 60 causes the movable-side engaging projection 56a and the fixed-side engaging projection 54a to be in between. The distance (distance between the pair of engaging projections) D1 changes. In other words, the engagement between the movable-side engagement projection 56a and the fixed-side engagement projection 54a toward the holding hole 2c is performed by the rotation of the lever 60. Thereby, it is not necessary to individually perform the operation for holding the cable 2 by the holding terminal 50 and the conduction connection of the joint 40, and the operability of the connector 1 can be improved.

Further, in the present embodiment, when the lever 60 is rotated in the closing direction and the entire spring portions 47 and 57 are deflected in the direction of the top wall portion 32, the spring portion 47 is in the middle of the rotation of the lever 60 in the closing direction. The slightly intermediate portion of the 57 is in contact with the top wall portion 32.

Further, as shown in FIG. 13, when the lever 60 is rotated in the closing direction and the entire spring portion 47 is deflected in the direction of the top wall portion 32, if the spring portion 47 is not in contact with the top wall portion 32, there is The stress generated by the deflection of the spring portion 47 and the movable side contact portion 46 is concentrated on the connection spring portion 43, and the connection spring portion 43 is caused to be tired. Further, similarly, in the holding terminal 50, the connection spring portion 53 is fatigued.

However, in the present embodiment, the middle portion of the spring portion 47 is brought into contact with the top wall portion 32 while the rod 60 is rotated in the closing direction, and when the movable side joint portion 42 is deflected, the joint 40 can be used. The stress generated by the deflection is concentrated on the contact portion where the spring portion 47 comes into contact with the top wall portion (the inner wall of the casing 30) 32. As a result, the stress applied to the connection spring portion 43 can be dispersed, and the stress concentration on the portion of the connection spring portion 43 that connects the movable side joint portion 42 and the fixed side joint portion 41 can be reduced, and the connection spring portion 43 can be prevented from being fatigued.

Further, when the lever 60 is rotated in the closing direction, the slightly intermediate portion of the spring portion 57 is brought into contact with the top wall portion 32. When the movable side holding portion 52 is deflected, the deflection of the holding terminal 50 can be caused. The generated stress concentrates on the contact portion where the spring portion 57 comes into contact with the top wall portion (the inner wall of the casing 30) 32. As a result, the stress applied to the connection spring portion 53 can be dispersed, and the stress can be concentrated on a portion of the connection spring portion 53 that connects the movable-side holding portion 52 and the fixed-side holding portion 51, and the connection spring portion 53 can be prevented from being fatigued.

Further, when the lever 60 is further rotated in the closing direction, the lever 60 is rotated to the closed position in a state where the slightly intermediate portion of the spring portions 47, 57 is in contact with the top wall portion 32. In other words, in the present embodiment, when the lever 60 is rotated in the closing direction and the movable side contact portion 46a and the fixed side contact portion 44a are pressed against the cable 2, the slightly intermediate portion of the spring portion 47 and the top wall are provided. The portion 32 is in contact (see Fig. 8). Further, although not shown, the holding terminal 50 also rotates the lever 60 in the closing direction in the same manner as the joint 40, and the holding portion 50 holds the cable 2, and the slightly intermediate portion of the spring portion 57 and the top wall portion 32 contacts.

Therefore, when the connector 1 is used (when the lever 60 is rotated to the closed position and the joint 40 and the holding terminal 50 are pressed against the cable 2), the stress applied to the connecting spring portions 43 and 53 can be dispersed, and therefore, Improve the product life of the connector 1.

Further, in the present embodiment, as shown in FIGS. 7 and 8, the base portion side in the vicinity of the step portions 47e and 57e provided in the slightly intermediate portion of the spring portions 47 and 57 is in contact with the top wall portion 32 (in FIG. 7 and In Fig. 8, although the joint 40 is shown, the holding terminal 50 is also the same. In other words, after the spring portions 47 and 57 are in contact with the top wall portion 32, the portions of the step portions 47e and 57e which are thinner at the distal end side are flexibly deformed upward.

By bending the spring portions 47 and 57 with the step portions 47e and 57e as the base points, the stress can be more efficiently concentrated on the spring portions 47 and 57. Therefore, it is possible to further suppress the joint spring portions 43, 53 from being fatigued.

As described above, in the present embodiment, the pivot shaft 61 of the lever 60 is housed in the bearing portion 35a of the lever mounting portion 35 which is opened at the upper side and the front side (one end side in the cable insertion/removal direction), and is covered. The holding fastener 70 accommodated above the pivot shaft 61 of the bearing portion 35a and in front (one end side in the cable insertion/removal direction) is provided in the connecting wall portion (housing) 34f. Therefore, even if the pivot shaft 61 moves toward the upper side or the front side of the bearing portion 35a (one end side in the cable insertion/removal direction), the movement can be restricted by holding the fastener 70, and the rod 60 can be prevented from being detached from the casing 30.

Further, even if the lever 60 is disengaged from the joint 40, the movement of the pivot shaft 61 in the front-rear direction and the vertical direction is restricted by holding the fastener 70 and the casing 30. Therefore, the rod 60 can be prevented from being detached from the casing 30. As described above, according to the present embodiment, since it is not necessary to engage the retaining fastener and engage the joint to restrain the rod from being detached from the housing, the rod 60 can be restrained from the shell only by the retaining fastener 70. Body 30 is detached.

In the present embodiment, the holding fastener 70 is provided on the connecting wall portion (housing) 34f so as to cover the upper side and the front side (one end side in the cable insertion/removal direction) of the pivot shaft 61 in a non-contact state.

Therefore, it is possible to suppress the occurrence of the rotation of the pivot shaft 61 from being hindered, and the pivot shaft 61 can be smoothly rotated. As a result, it is not necessary to perform high-precision dimensional management such as cutting processing for ensuring the rotation of the pivot shaft 61.

The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications can be made.

For example, the shape of the holding fastener and the pivotal shaft covering portion is not limited to those described in the above embodiment, and can be various shapes.

Further, in the above-described embodiment, the connector in which the lever is turned downward and the cable insertion direction is described as an example. However, the present invention can also be implemented in a connector in which the lever is turned downward and the cable is detached.

Further, the specifications (shape, size, arrangement, and the like) of the casing, the rod, the cam portion, and other details may be appropriately changed.
