Please refer to Figure 7, when the components are combined, each lever 30 is movably assembled in the housing 10, and due to the size of the cam 33, the lever 30 and the housing 10 can swing and move relative to each other The swinging motion of the fixed axis, wherein, the dial 31 of the shift lever 30 is located outside the accommodation space 113 of the casing 10, and each cam 33 is located inside the accommodation space 113, and each cam 33 is located in the conductive part 22 and the extension 2122 of the spring clip 21; the fixed surface 331e and the top support surface 331f of the cam 33 form the pushing edge of the driving lever 30 when it swings, and the starting and positioning of the cam 33 The surface 331b, the second abutting surface 331c and the initial positioning surface 331d form a propping edge for the lever 30 to contact the conductive member 22 when it swings.

Please refer to FIG. 7, when the lever 30 is at the initial position P1, the initial positioning surface 331d of the cam 33 can contact the contact block 221 of the conductive member 22, and at the same time, its actuating positioning surface 331b faces the engagement of the conductive member 22. Block 222, and in this embodiment, when the cam 33 is in the initial position P1, the cam 33 does not touch the elastic section 212c of the spring clip 21, so that the elastic section 212c presents an initial state A1 without deformation. The portion 2123 blocks the window 212d in the insertion direction so that the wire cannot enter the window 212d.

As shown in FIG. 7 , in this embodiment, when the lever 30 is at the initial position P1, the lever 30 can move horizontally and linearly relative to the casing 10, and can move toward the locking block 222 or toward the casing. The wire insertion hole 112 of 10 moves.

Please refer to FIG. 8A , when the lever 30 swings relative to the housing 10 in the direction of the arrow in the figure and away from the initial position P1, the cam 33 will swing relative to the housing 11 of the housing 10, The top weighing surface 331f will contact and push against the elastic section 212c, while the initial positioning surface 331d will separate from the contact block 221 and contact the contact block 221 with the second pushing surface 331c.

As shown in the figure, when the driving lever 30 is actuated so that the first and second pushing surfaces 331a and 331c of the cam 33 respectively contact the blocking block 222 and the contacting block 221, the initial positioning surface 331d of the action profile 331 and the fixed surface 331e are two When neither of them is in contact with the lead unit 20, the supporting surface 331f of the action profile 331 will be able to contact and push against the elastic section 212c of the clamping part 212, so that the elastic section 212c faces the connection section of the clamping part 212 212a is deformed, so that the elastic section 212c changes from the initial state A1 to a deformed state A2.

Wherein, as shown in the figure, due to the position of the joint 2121a between the reflexed portion 2121 and the extension portion 2122 of the elastic section 212c, it is located on the right side of the top supporting surface 311f in the horizontal direction when the driving lever 30 is in the initial position P1 (according to direction in the figure), and the first section 2122a of the extension part 2122 extends away from the loading plate 211, so that when the cam 30 swings, the first section 2122a will form a surface no matter it is in the initial state A1 or the deformed state A2 The direction is towards the inclined surface extending to the left in the figure, and the contact position between the supporting surface 331f and the elastic section 212c will first be formed on the first section 2122a, and keep the shielding part 2123 away from the conductive member 22. Therefore, when the cam 33 swings When contacting the first section 2122a, the cam 33 will be guided to slide to the left by the force provided by the first section 2122a instead of sliding to the right. According to the above description, when the cam 33 swings, the second abutting surface 331c of the cam 33 can slide to the right side relative to the conductive member 22 and rotate counterclockwise, so that the first abutting surface 331a contacts the abutting block 222 .

Afterwards, the first abutting surface 331a will contact the abutting block 222 of the guide unit 20 as the cam 33 moves (in some embodiments, the abutting block 222 can be deformed by being pressed by the cam 33), and at the same time, The action cam 33 changes the area where the action profile 331 is in contact with the guide unit 20, so that the surface of the cam 33 in contact with the contact block 221 will change from the initial positioning surface 331d to the second pushing surface 331c; During the process, the driving lever 30 can change from the state of not being affected by the elastic section 212c to the state being pushed by the elastic section 212c, and when the turning stroke of the driving lever 30 reaches the end (as shown in Figure 9A), the elastic piece provides The resistance of the cam 30 is directly transmitted to the conductive member 22 by the shape design of the cam 30, so that the difference in the user's operating feel (resistance) can be generated.

Also, as shown in FIG. 8A , in this embodiment, due to the angle between the first section 2122a and the second section 2122b and the length design of the second section 2122b, the second cam 33 swings in the process of swinging. The segment 2122b will be driven by the first segment 2122a to approach the connecting segment 212a, and the shielding portion 2123 will be driven by the second segment 2122b to move away from the conductive member 22 .

Please refer to FIG. 8B , in this embodiment, when the driving lever 30 moves away from the initial position P1, the pressing surface 342 of the driving lever 30 will keep a certain distance from the guiding surface 122 of the casing 10, So that the pressing surface 342 will not be in contact with the guiding surface 122, however, the pressing surface 342 will not be in contact with the guiding surface 122 is only for convenience of illustration. In another embodiment, as shown in FIG. During the swinging process relative to the housing 10 , the pressing surface 342 will contact the guiding surface 122 , so that the stop surface 341 of the driving lever 30 can gradually approach the abutting surface 123 of the cover 12 .

Please refer to FIG. 9A and FIG. 9B , when the lever 30 continues to swing relative to the housing 10, so that the first pushing surface 331a of the cam 33 keeps approaching the contact block 221 of the conductive member 22, the cam 33 keeps pushing against the contact block 221 of the conductive member 22. The elastic section 212 c of the spring clip 21 makes the shielding portion 2123 of the elastic section 212 c closer to the connection section 212 a and away from the conductive member 22 .

When the lever 30 continues to swing and the stop surface 341 of the connecting arm 32 contacts the abutting surface 123 of the cover 12, because the abutment recess 35 presents a tapered shape S3, the abutment block 222 of the conductive member 22 is easily Enter into the interior of the engaging recess 35 of the shift lever 30; wherein, when the engaging block 222 is located inside the engaging recess 35, the first engaging surface 353 of the engaging recess 35 and the engaging end surface 351 of the engaging recess 35 The two are in contact with different sides of the locking block 222, and the first locking surface 353 will be in surface contact with the surface of the locking block 222, thereby allowing the driving lever 30 to stop swinging relative to the housing 10 (that is, at some The shorter embodiment of the locking block 222 can also stop the swing of the driving lever 30 without touching the bottom end surface 351 of the card), in addition, because it is formed in the interval between the first and second locking surfaces 353, 354 The distance H is greater than the thickness of the locking block 222. When the first locking surface 353 and the locking end surface 351 are in contact with different sides of the locking block 222 at the same time, the second locking surface 354 is arranged at intervals on the locking block 222. The surface that is not in contact with the blocking block 222 .

It can also be seen from FIG. 9A that in this embodiment, since the thickness of the locking block 222 corresponds to the thickness of the locking end surface 351 and the locking recess 35 presents a tapered shape S3, when the first locking surface 353 and the locking end surface When both 351 and 351 are in contact with different sides of the locking block 222 at the same time, one side of the locking block 222 is pushed against the first locking surface 353, and the tip will just be locked against the locking end surface 351, so that the lever 30 cannot be used on the other side. horizontal movement in the insertion direction; in addition, even if the cam 30 does not fully contact the locking block 222 during the swinging process of the driving lever 30, because the extending direction of the locking block 222 and the insertion direction present an obtuse angle and the locking recess 35 presents a tapered In the state S3, the driving lever 30 can be guided by the locking block 222 and the locking bottom recess 35 to move toward the locking block 222 when swinging.

As can be seen from the above, in this embodiment, the cam-type wire connector 1 includes two positioning structures that prevent the lever 30 from continuing to rotate after the shrapnel (elastic section 212c) is transformed into an activated state. The positioning structure includes a through shrapnel (elastic section 212c) The first positioning structure formed by the section 212c) and the cam 33 and the second positioning structure formed by the locking block 222 and the locking recess 35 of the conductive member 22 prevent the user from mistakenly thinking that the lever 30 has not been moved. Push to the location and continue to apply force to the driving lever 30.

In addition, in this embodiment, through the similar concept of preventing the rotation of the lever 30 by making the first engaging surface 353 contact with the engaging block 222, in another embodiment of the present case, the profile of the cam 33 can be changed The second positioning structure is formed by setting a position and angle corresponding to the plane of the first engaging surface 353 in this embodiment on the cam 33, without setting the engaging recess 35; or in other embodiments, you can The first engaging surface 353 is aligned with a part of the surface of the cam 33 .

As shown in the figure, in this embodiment, when the lever 30 touches the cover 12 of the housing 10, the locking block 222 will contact the locking recess 35 at the same time to stop swinging relative to the housing 10, and let the The lever 30 cannot move linearly parallel to the insertion direction relative to the housing 10, and the surface of the cam 33 of the lever 30 in contact with the contact block 221 changes from the second pushing surface 331c to the activation positioning surface 331b, so that the cam 33 The fixed surface 331e is in contact with the elastic section 212c, so that the lever 30 stays at a starting position P2 where the spring clip 21 can be deformed, and then the elastic section 212c remains in the deformed state A2, and at the same time, the elastic section 212c also maintains At a position away from the conductive member 22 , a wire insertion channel is formed for the wire to enter the window 212 d.

As can be seen from the figure, in this embodiment, when the driving lever 30 is located at the starting position P2, the first abutting surface 331a of the action profile 331 is in contact with the abutting block 222 of the guide unit 20, and the second push surface 331a of the action profile 331 The contact surface 331c, the initial positioning surface 331d and the supporting surface 331f are not in contact with the conductive unit 20; the activation positioning surface 331b is in surface contact with the conductive member 22, and the fixed surface 331e is in surface contact with the second section 2122b. Both the activation positioning surface 331b and the fixing surface 331e are roughly parallel, and the projection position of the fixing surface 331e in the vertical direction will be located in the activation positioning surface 331b, so when the second section 2122b acts on the cam 33 (fixing surface 311e ) The active force will move toward the start positioning surface 331b without generating a moment capable of rotating the cam 33, and when the start position P2 is reached, the user's feel when operating the shift lever 30 will be changed; Swing, the lever 30 can also return to the starting position P2 under the influence of the elastic section 212c.

In addition, it can also be seen from FIG. 9A that when the driving lever 30 is at the starting position P2, since the cam 33 abuts against the second section 2122b and the conductive member 22 in the vertical direction, the driving lever 30 can be prevented from moving in the vertical direction, and the cam 33 through the first pushing surface 331a toward the right side against the block 222, and the block 222 against the depression 35 at the bottom of the card, so as to prevent the driving lever 30 from rotating counterclockwise, so that two-dimensional rotation can be performed at the initial position P1. The position and rotation angle of the moving lever 30 after moving to the starting position P2 are fixed, and when the driving lever 30 leaves the starting position P2, it is easier to swing away from the starting position P2.

In addition, in other embodiments, since the cam 33 is pushed against by the blocking block 222 and the first section 2122a on the left and right sides respectively, even if the aforesaid activation positioning surface 331b and the fixing surface 331e are not parallel to each other, the fixing surface 331e Under the condition that the force can be projected on the starting positioning surface 331b in the direction of the force, the driving lever 30 will not rotate due to the action of the spring clip 21 when it is in the starting position P2.

Please refer to FIG. 10 and FIG. 11 , after the lever 30 is in the starting position P2, the wires 40 can respectively pass through the insertion holes 112 of the housing 10 into the housing space 113 of the housing 10, and the wires 40 can be Pass through the elastic section 212c of the spring clip 21 and the guide block 223 of the conductive member 22 , and pass through the window 212d of the spring clip 21 , so that the end of the wire 40 can approach the cover 12 of the housing 10 . Afterwards, during the process of moving the lever 30 back from the starting position P2 to the initial position P1, the cam 33 of the lever 30 changes the position of the elastic section 212c acting on the spring clip 21, so that the elastic section 212c pushes against the wire 40 is close to the conductive member 22, and then the wire 40 is pressed against the conductive member 22, whereby the wire 40 can pass through the conductive member 22 and electrically connect with another wire 40 on the other window 212d (the viewing angle relationship is blocked). In addition, as can be seen from FIGS. 10 and 11 , when the wire 40 enters the window 212d, the position of the connection 2121a between the reflexed portion 2121 and the first section 2122a will be closer to the wire 40 than the extension portion 2122 .

Please refer to FIG. 12 , in the second preferred embodiment, the difference from the first preferred embodiment is that the blocking block 222 of the conductive member 22 is from the carrier plate 211 of the spring clip 21 toward the spring clip 21 The connection section 212a is extended and formed, and the structure of both the housing 10 and the lever 30 is the same as that of the wire connection device 1 of the first preferred embodiment described above. Furthermore, the use method in this embodiment It is the same as the first preferred embodiment, so it will not be repeated in this embodiment.
