However, the present invention may be practiced without the specific details. Furthermore, it is to be understood that the various embodiments shown in the drawings are illustrative representations and are not necessarily drawn to scale.

The present invention will be further described below in conjunction with the accompanying drawings.

first embodiment

FIG. 1 is an exploded view of a terminal 100 with operational sound feedback according to a first embodiment of the present invention. FIG. 2 is a side view of the connection terminal with operating sound feedback according to the first embodiment of the present invention in a state of being clamped. 3A-3C are cross-sectional views of a terminal with operational audible feedback according to a first embodiment of the present invention at initial, intermediate and completed stages of operation.

As shown in FIG. 1 , FIG. 2 , and FIGS. 3A-3C , the terminal 100 includes a housing 110 , and a wire clamping spring 120 and a flow guiding structure 130 in the housing. A spring holding portion 111 is also formed in the housing 110 , which is usually integrally formed with the housing 110 . A wire clamping spring structure, such as wire clamping spring 120 , is used to fit within housing 110 by means of spring retainer 111 . Specifically, the wire clamping spring 120 includes a curved portion 123 , one end of the curved portion 123 is connected to the clamping arm 121 , and the other end is connected to the holding structure 122 . The holding structure 122 is divided into two sections, the first section and the clamping arm 121 form a U-shaped structure, the second section is bent at a near right angle compared to the first section, and a window is formed on the second section. The clamping arm 121 extends into this window. The second segment can also be referred to as the snap arm. A snap-fit tab 124 is also formed where the end of the first segment of the holding structure 122 is bent.

The guide structure 130 is a component made of metal or other conductive materials. In the assembled state shown in FIG. 2 , the guide structure 130 is placed in the bottom space of the housing 110 , and the bayonet of the guide structure 130 and the snap-fit tab 124 on the holding structure 122 of the wire clamping spring 120 Joining together takes place by snapping.

The housing 110 also includes a wiring channel 180 for the entry and exit of the wire 140, and an operation channel 185 for accommodating the screw 150 and for the entry and exit of a screw operating tool 190 (eg, a bit of a screwdriver). Specifically, the nut member 170 is placed in the lower part of the operation channel 185 , and the inner thread of the nut member 170 is matched with the outer thread of the screw rod 152 of the screw 150 . Therefore, when the screw head 151 of the screw 150 is rotated by the operating tool, the screw 150 can convert the rotation operation into the up and down movement operation within the operation channel 185 . The operating channel is divided into two sections, the diameter of the upper channel corresponds to the diameter of the screw head 151 , and the diameter of the lower channel corresponds to the diameter of the screw 152 . In the upper passage, an annular stop structure 186 is provided, and the diameter of the upper passage decreases at this position, preventing the screw head 151 from passing through this area, so the annular stop structure 186 limits the upper limit of the stroke of the screw 150 . In addition, when the screw head 151 descends to the upper channel end 187, it cannot continue to descend, so the upper channel end 187 defines the lower limit of the travel of the screw 150.

When the screw 150 reaches the lower limit of travel along the operating channel 185, the lower portion of the screw 152 squeezes the clamping arm 121, causing the clamping arm 121 to pivot around the connecting portion 123 (clockwise pivoting in FIGS. 2 and 3A ) Therefore, the end of the clamping arm 121 no longer blocks the end of the wire 140 (ie, the wire end 141 ) from reaching the bottom space of the housing 110 and making sufficient contact with the flow guiding structure 130 . In this state, the operator can fully insert the wire 140 into the wiring channel 180 . After the wire 140 is in place, the screw 150 can be reversely rotated with an operating tool, so that the position of the screw 150 can be gradually raised, thereby releasing the pressing of the clamping arm 121 . After the extrusion from the screw 150 is released, the clamping arm 121 generates a return movement by its own elastic force, and abuts against the wire end 141 of the wire 140 , thereby clamping and positioning the wire 140 . At this point, the wiring operation is completed.

According to the first embodiment of the present invention, a sound feedback device is added in the operation channel 185, and the sound feedback device can trigger the reset action by the change of the position of the screw 150, and emit a sound during the reset action. Therefore, in the screw-removing stage of the wiring operation, it can be accurately judged whether the operation stroke of the screw-removing is completed.

The sound feedback device in the first embodiment is specifically implemented as a compression spring 161 , a spherical stopper 162 , a blind hole 163 in the housing 110 , and a compression spring post 164 in the blind hole 163 . The compression spring 161 is located in the blind hole 163 , one end of the compression spring 161 is sleeved on the compression spring post 164 , and one end is connected to the ball stopper 162 and applies pressure to it. In the clamped state shown in Figures 2 and 3C, or in the unwired idle state, the screw head 151 of the screw 150 may be located at the upper travel limit limited by the annular stop structure 186, at which position the screw The concave ring structure 153 of the head 151 partially presses the spherical blocking member 162 into the blind hole 163 .

The audible feedback device of the first embodiment is configured to provide audible feedback to indicate that the withdrawal movement of the screw 150 is in place during a screw-out operation that drives the screw 150 back out (ie, moves up the operating channel). Figure 3A shows a cross-sectional view of an initial stage of operation. FIG. 3B shows a cross-sectional view at an intermediate stage of operation, and FIG. 3C shows a cross-sectional view at a completed stage of operation. In the initial stage of the operation shown in FIG. 3A , the screw 150 is located at the lowermost position of the operating channel, so the threaded rod 152 of the screw 150 presses the clamping arm 121 of the spring. The rotation of the tool 190 can make the screw 150 rise to the state shown in FIG. Finally, the rotation of the tool 190 can further raise the screw 150 to the state shown in FIG. 3C . At this time, the concave ring structure on the screw head 151 is facing the entrance of the blind hole 163 , so the spherical stopper 162 is in the compression spring 161 . Under the action of the thrust force, it enters the annular concave hole portion of the screw head 151 from the blind hole 163, and collides, producing a sound. Therefore, the terminal alerts the user in the form of audible feedback that the screw 150 has been screwed to the end of the unscrewing stroke.

Second Embodiment

FIG. 4 is an exploded view of a terminal 100 with operational sound feedback according to a second embodiment of the present invention. FIG. 5 is a side view of the connection terminal with operating sound feedback according to the first embodiment of the present invention in a state where the wires are clamped. 6A-6C are cross-sectional views of a terminal with operating acoustic feedback according to a second embodiment of the present invention at initial, intermediate and completed stages of operation.

In FIGS. 4 , 5 , and 6A-6C, the structures of the wire clamping spring 220 , the guide structure 230 , the wire 240 , and the nut 270 are basically the same as those of the first embodiment, so they will not be repeated.

In the second embodiment, the casing 210 and the casing 110 of the first embodiment have the same part of the structure. One difference between the two is that another sound feedback device is provided in the operation channel 285 of the second embodiment. The sound feedback device can trigger the reset action by the change of the position of the screw 250, and emit sound during the reset action.

More specifically, the sound feedback device in the second embodiment is embodied as a specific flexible frame body 260 . As shown in FIGS. 5 and 6A-6C , the flexible frame body 260 includes a fixed end 261 connected to the outer frame of the casing 210 , and also includes a flexible free end 262 that is not in contact with the outer casing of the casing 210 . The free end 262 can partially protrude into the operation channel 285 through the opening on the wall of the operation channel 285 in a natural state without being squeezed. In the state shown in FIG. 6B , the head 251 of the screw 250 and the free end 262 of the flexible frame body 260 are squeezed and the flexible frame body 260 undergoes a flexural deformation.

The audible feedback device of the second embodiment is configured to provide audible feedback to indicate that the withdrawal movement of the screw 250 is in place during a screw-out operation that forces the screw 250 to withdraw (ie, move up the operating channel). Figure 6A shows a cross-sectional view of the initial stage of operation. Figure 6B shows a cross-sectional view at an intermediate stage of operation. Figure 6C shows a cross-sectional view at the completion stage of the operation.

In the initial stage of the operation shown in FIG. 6A , the screw 250 is located at the lowermost position of the operation channel, so the threaded rod 252 of the screw 250 presses the clamping arm 221 of the spring. The rotation of the tool 290 can make the screw 250 rise to the state shown in FIG. 6B , therefore, the screw head 251 begins to squeeze and deform the flexible frame 260 , and accumulates the energy generated by the deformation. Finally, the rotation of the tool 290 can further raise the screw 250 to the state shown in FIG. 6C . At this time, the screw head 251 no longer presses the flexible frame body 260 , the deformation of the flexible frame body 260 is restored, and the During the process, there is a sound due to the collision. Therefore, the terminal alerts the user by way of audible feedback that the screw 250 has been screwed to the end of the unscrewing stroke.

The flexible frame body 260 can also be formed as a flexible plate, or any other flexible structure.

Third Embodiment

FIG. 7 is an exploded view of a terminal 300 with operational sound feedback according to a third embodiment of the present invention. FIG. 8 is a side view of the connection terminal with operating sound feedback according to the first embodiment of the present invention in a state of being clamped. 9A-9C are cross-sectional views of a terminal with operating acoustic feedback according to a second embodiment of the present invention at initial, intermediate and completed stages of operation.

In FIGS. 7 , 8 , and 9A-9C , the structures of the wire clamping spring 320 , the guide structure 330 , the wire 340 , and the nut 370 are basically the same as those of the first embodiment, so they will not be repeated.

In the third embodiment, the parts of the housing 310 and the housing 110 of the first embodiment have the same structure. One difference between the two is that another sound feedback device is provided in the operation channel 385 of the third embodiment. The sound feedback device can trigger the reset action by the change of the position of the screw 350, and emit sound during the reset action.

More specifically, the sound feedback device in the third embodiment is embodied as a specific rotary vane 360 and a compression spring 366 , and corresponding structures such as a rotary vane shaft 365 and a blind hole 368 in the housing 310 . As shown in FIGS. 8 and 9A-9C, the vanes 360 are mounted on the vane shaft 365 near the operating channel 385 so as to be able to pivot. The vane 360 includes a first end 361 and a second end 362 . Wherein, the first end 361 of the rotary vane 360 can be pivoted to enter the operation channel 385 , and the second end 362 of the rotary vane 360 can be between the first pivot position and the second pivot position limited by the structure of the housing 310 pivot.

In the first pivot position shown in FIG. 9A , the vane 360 is substantially perpendicular to the operating channel 385 and the first end 361 of the vane 360 enters the operating channel 385 at this time. In the second pivot position shown in FIG. 9B , the vane 360 is inclined to the operating channel 385 and the first end 361 of the vane 360 is now away from the operating channel 385 (ie, does not occur with the movement of the screw 350 within the channel). put one's oar in). Also, in the second pivot position, the compression spring 366 accommodated in the blind hole 368 is pressed by the first end 362 of the rotating vane 360, thereby accumulating elastic potential energy.

The audible feedback device of the third embodiment is configured to provide audible feedback to indicate that the withdrawal movement of the screw 350 is in place during a screw-out operation that drives the screw 350 to withdraw (ie, move up the operating channel). Figure 9A shows a cross-sectional view of the initial stage of operation. Figure 9B shows a cross-sectional view at an intermediate stage of operation. Figure 9C shows a cross-sectional view at the completion stage of the operation.

In the initial stage of the operation shown in FIG. 9A , the screw 350 is located at the lowermost position of the operation channel, so the threaded rod 352 of the screw 350 presses the clamping arm 321 of the spring. The rotation of the tool 390 can cause the screw 350 to rise to the state shown in FIG. 9B. During this process, the screw head 351 presses the first end 361 of the vane 360, so the upward movement of the screw head 351 pushes the vane 360 to rotate ( 9B), the second end 362 of the rotary vane 360 presses the compression spring 366 to accumulate elastic potential energy. The rotation of the rotary vane 360 is finally limited by the structure in the housing, and ends in the second pivot position state in FIG. 9B . When the position of the screw 350 is further raised to the position shown in FIG. 9C , the screw head 351 releases the pressing on the first end 361 of the rotary vane 360 , and the rotary vane 360 recovers under the action of the elastic force of the compression spring 366 . The collision makes a sound, and in the form of sound feedback, the user is reminded that the screw 350 has been screwed to the end of the screw-removing operation stroke.

In some variations, the acoustic feedback device is configured as any suitable mechanism that accumulates energy in response to a change in the position of the operating member during the initial or intermediate stages of the operating stroke and releases it at the end of the operating stroke energy to make sound.

In some variations, the screw can be replaced by any operating member with a head and a screw, or by other forms of operating member suitable for placement in the operating channel of the housing and movable in position.

In some variations, the wire clamp spring is not a caged return spring, but a U-shaped leaf spring, or any other suitable wire clamp spring structure.

In some variations, the audible feedback device is configured to provide audible feedback during the screw-in operation stroke, or separately during the screw-in operation and the screw-out operation.
