The crimping member 141 is driven to be crimped to the core 210 of the cable 200, so that the conductive sheet 310 is electrically connected to the core 210. At the same time, the crimping member 142 crimps the crimping block 314 to the (insulation layer) of the cable 200 to allow the housing 300 to be secured to the cable 200.

It is also mentioned that, referring again to FIG. 2, the crimping hand tool 10 further includes a first cutter 170 that is assembled to and moves with the crimping member 141 of the crimping assembly 140 by the coupling members A6, A7. While the crimping assembly 140 is crimping, the first cutter 170 also cuts off the portion 212 of the core 210 that protrudes from the outside of the housing 300 to allow the core portion of the cable connector to be coupled to the housing. 300 is aligned, and the state is as shown in FIG. At this point, the crimping action of the cable 200 and the housing 300 is completed.

Referring to FIG. 2 , FIG. 5 and FIG. 6 , the crimping hand tool 100 of the present embodiment further includes a resetting assembly 160 including a connecting member 161 and a first elastic member 162 , wherein the connecting member 161 is disposed on the body 131 of the linking member 130 . The opening 131a is moved with the linkage 130, and the first elastic member 162 is coupled between the coupling member 161 and the convex portion 116 of the first caliper body 110. According to this, when the crimping operation is performed, the linking member 130 is driven by the first caliper body 110 to push the crimping assembly 140 into the crimping groove SL1, and the first elastic member is in a state in which the connecting member 161 moves with the body 131. 162 will be stretched and deformed (as shown in FIG. 6), so that when the crimping operation is completed and the user releases the force required for the crimping, the first elastic member 162 can drive the linking member 130 and the crimping assembly 140 to be reset. And restore the position shown in Figure 5. In other words, the first elastic member 162 constantly drives the crimping assembly 140 to move away from the crimping groove SL1 of the first caliper body 110 via the linking member 130.

Referring to FIG. 2 and FIG. 7 again, the linking member 130 of the crimping hand tool 100 further has a ratchet structure 132 adjacent to the pivoting portion of the linking member 130 and the second caliper body 120, and the ratchet portion 132a of the ratcheting structure 132 is further It can be further divided into a first segment E1 and a second segment E2, wherein the first segment E1 has a dense ratchet structure. Correspondingly, the crimping hand tool 100 further includes a stop assembly 150 including a second elastic member 151, a stop block 152 and a knob 153, wherein the stop block 152 is rotatably disposed on the second caliper body 120 via the knob 153. And a part of the knob 153 is exposed outside the second tong body 120 to facilitate the user to apply force. One end of the second elastic member 151 is coupled to the stopper block 152, and the other end thereof is coupled to the second caliper body 120 via the coupling member A5. Furthermore, the portion of the stopper 152 (i.e., the convex portion 152a shown in FIG. 2) interferes with the movement path of the ratchet structure 132, and thus the process of opening the first caliper body 110 and the second caliper body 120 to each other is opened. The user can rotate the stopper 152 by applying a force to the knob 153 to temporarily lock the stopper block 152 to the ratchet structure 132, thereby temporarily fixing the first caliper body 110 and the second caliper body 120 to the second caliper body 120. Required opening status. As shown in FIG. 7, at this time, the convex portion 152a of the stopper block 152 is temporarily fixed to the first segment E1 of the ratchet portion 132a, and when the state is to be released, the user only needs to apply the force to the knob 153. The convex portion 152a is moved to the second segment E2, that is, the aforementioned snap state can be released.

In addition, since the direction in which the second elastic member 151 drives the stopper 152 is opposite to the direction in which the ratchet structure 132 drives the stopper 152, that is, when the user drives the stopper 152 via the knob 153 to release the ratchet structure. After the snap relationship of 132, the second elastic member 151 can drive the stop block 152 to rotate and reset by its elastic force.

The position of the ratchet structure and the stop assembly is not limited here. Figure 8 is a partial cross-sectional view of a crimping hand tool of another embodiment of the present invention. Referring to FIG. 8, the difference from the foregoing is that in the crimping hand tool 500 of the present embodiment, the ratchet structure 532 is disposed on the second caliper body 532 (ie, the upper half of the member shown in the figure), and the stopper block The 552 and the second elastic member 551 are separately provided to the body 531 of the linking member, thereby producing a structural design opposite to that of the foregoing embodiment, but still maintaining the same snapping effect as the foregoing embodiment.

Figure 11 is a schematic view of the stripping of the cable. 12 to 14 are respectively schematic views of the stripping of the crimping hand tool of Fig. 1. Referring to FIG. 2 , in the embodiment, the wire stripping assembly 180 includes a sliding member 181 , a second cutter 182 and a third elastic member 183 , wherein the sliding member 181 is slidably coupled to the first caliper body 110 along the X axis. The sliding portion 115 (which is, for example, a groove formed by the annular lip portion), except that the sliding member 181 is slidably clamped to the sliding portion 115, can expose the push handle portion 181a of the sliding member 181 to The first caliper body 110 facilitates the user to apply force. The second cutter 182 is embedded in the slider 181. Correspondingly, the first caliper body 110 further has a rib 114 located in the second housing 111b and corresponding to the sliding member 181, so that the portion of the sliding member 181 corresponding to the rib 114 together forms the stripping groove SL2, and the sliding member 181 Moving along the X axis can thus change the inner diameter profile of the stripping groove SL2. Furthermore, one end of the third elastic member 183 is sleeved on the protruding post 181b of the sliding member 181, and the other end abuts against the convex portion 118 of the first caliper body 110. Here, the third elastic member 183 constantly drives the sliding member 181. Move closer to the ribs 114.

In this way, as shown in FIG. 12 to FIG. 14 , before the wire stripping is performed, the user applies a force to the push handle 181 a to drive the slider 181 to move in the negative X-axis direction, as shown in FIG. 12 . The process of FIG. 13 is such that the inner diameter of the stripping groove SL2 can be larger than the cable 400, so that the user inserts the cable 400 into the stripping groove SL2, and then the user releases the aforementioned force to make the third The elastic member 183 drives the slider 181 to move toward the rib 114, so that the cable 400 can be clamped between the slider 181 and the rib 114, as shown in the processes of FIGS. 13 to 14. Accordingly, the second cutter 182 can be abutted against the cable 400, and the portion of the second cutter 182 protruding from the slider 181 (located in the stripping groove SL2) is substantially smaller than or equal to the thickness of the insulating layer 420. Therefore, the aforementioned clamping action can also cause the second cutter 182 to cut into the insulating layer 420 of the cable 400. Of course, the user can also apply force to the push handle 181a to drive the slider 181 to further move toward the rib 114 until the outer contour of the cable 400 abuts the inner contour of the stripping slot SL2, and the second cutter can be achieved. The 182 is cut into the insulating layer 420 but is prevented from causing damage to the core 410. Accordingly, the user holds the cable 400 in one hand, and the other hand drives the crimping tool 100 to rotate along the outer contour of the cable 400 (the rotation can also be rotated to change the cable 400), that is, the second cutter 182 can be made. The outline of the cable 400 is cut along the outline of the cable 400, thereby causing the insulating layer 420 to be cut away.

Here, in order to allow the stripping assembly 180 to be smoothly disposed on the first caliper body 110 and effectively reduce the volume to facilitate gripping, the sliding axial direction of the stripping assembly 180 of the present embodiment is substantially opposite to that of the crimping assembly 140. The sliding axial direction is uniform (all along the X axis), and the wire stripping assembly 180 is adjacent to the pivotal joint of the first caliper body 110 and the second caliper body 120, and the crimping assembly 140 is away from the first caliper body 110 and the second caliper body 120. The pivoting portion is such that the stripping assembly 180 is located between the crimping assembly 140 and the nipper pivoting portion, and the sliding member 181 is located between the linking member 130 and the sliding portion 115 of the first caliper body 110, and the sliding member 181 The sliding path does not overlap with the moving path of the linking member 130.

In summary, in the above embodiment of the present invention, the crimping hand tool is connected to the first caliper body and the second caliper body by being pivotally connected to each other, and is matched with the linking member between the two to make the first When the caliper body and the second caliper body rotate and rotate together, the linking member is rotated by itself and driven by the sliding guiding effect of the guiding structure on the crimping assembly to form an axial movement for the signal line and the housing. Driven by the crimping assembly and pressed together.

In addition, the crimping hand tool further has a stripping assembly disposed on the first caliper body, so that when the user needs to strip the cable, the cable can be threaded through the first tong body and stripped by the wire. The component peels off the insulation layer of the cable from the core of the cable, thereby allowing the user to complete the required crimping and stripping operation with a single hand tool, thereby improving the application range of the crimping hand tool.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the novel creation, and any person skilled in the art can make some changes without departing from the spirit and scope of the novel creation. Retouching, the scope of protection of this new creation is subject to the definition of the scope of the patent application attached.
