According to this, when the second caliper body 120 is rotated and opened relative to the first caliper body 110, the linking member 130 is thus driven to slide and rotate in the first caliper body 110, thereby driving the crimping assembly 140 along the crimping direction. The housing 300 is crimped together with the core 210. Here, the crimping direction is a positive Y-axis direction orthogonal to the pivotal axial direction (X-axis) of the first caliper body 110 and the second caliper body 120 and away from the first caliper body 110 and the second caliper body 120 Pivot.

In the present embodiment, the main space of the first crimping groove 111 is located in the body 113, and the opening thereof is located at the side plates 114a, 114b, and the first crimping groove 111 communicates with the accommodating space R1 along the Y-axis via the groove body 117a. Here, the first crimping groove 111 has a penetrating structure along the X axis, so that the housing 300 can be placed in the first crimping groove 111 after the core 210 is inserted, and the crimping operation is performed. Furthermore, the first crimping member 141 and the second crimping member 142 are respectively pivotally connected to the first end E1 of the linking member 130 via the pivoting shaft 144 to be driven by the linking member 130 to make a part of the first crimping member 141. The first crimping groove 111 is inserted into and out of the second crimping member 142 in synchronization with a portion of the second crimping member 142 and is used to crimp the different portions of the housing 300. Along the X-axis, the linking member 130 is located between the first crimping member 141 and the second crimping member 142.

On the other hand, the crimping hand tool 100 further includes a first cutter 151 assembled to the first crimping member 141, and the first cutter 151 enters and exits the first crimping groove 111 with the first crimping member 141 to be aligned with the core 210. The portion outside the housing 300 will be further described later.

However, as described above, the first crimping groove 111 and the second crimping groove 112 are different only in the form of the housing and the signal line to be applied. Accordingly, the crimping assembly 140 further includes a third crimping member 143 coupled between the first crimping member 141 and the second crimping member 142, and along with the first crimping member 141 and the second crimping member 142. mobile. The third crimping member 143 and the other portion of the second crimping member 142 are synchronously inserted into the second crimping groove 112, that is, similar to the first crimping member 141 and the second crimping member 142, respectively. A crimping groove 111 is configured to press the housing 300 that enters the first crimping groove 111 with the core 210 and the conductive sheet 310, and for the third pressure to enter and exit the second crimping groove 112. The connector 143 also needs another structure to simultaneously enter and exit the second crimping slot 112 to crimp the other housing, the core and the conductive sheet. Therefore, in the embodiment, the second crimping member 142 is substantially Divided into two parts, wherein the first indenter 142a is used to enter the first crimping slot 111 in synchronization with the first crimping member 141, and the second indenter 142b is used to synchronize with the third crimping member 143. Two crimping slots 112. Here, the first indenter 142a and the second indenter 142b are of a unitary structure, which is advantageous for reducing the overall number and volume of the components and being simple in design. Of course, in other embodiments not shown, the first indenter and the second indenter can be separated into different members by changing the structural design. Correspondingly, the crimping hand tool 100 also needs to be provided with a second cutter 152 corresponding to the second crimping groove 112, which is assembled to the third crimping member 143 and then enters and exits the second crimping groove 112 for convexly pressing. The cores are cut and aligned.

FIG. 4 and FIG. 5 respectively show schematic views of the crimping hand tool in different states, where the partial components are shown by dashed lines to achieve a see-through effect, and the subsequent description is facilitated. Referring to FIG. 3 to FIG. 5 simultaneously, in the embodiment, the crimping hand tool 100 further includes a ratchet structure 171 and a stopping block 172, wherein the ratcheting structure 171 is disposed on the second caliper body 120 and moves with it, stopping The block 172 is rotatably disposed on the first caliper body 110, and a portion of the stopper 172 interferes with the moving path of the ratchet structure 171 to stop when the first caliper body 110 and the second caliper body 120 are relatively open. Block 172 temporarily snaps ratchet structure 171 as shown in FIG.

In detail, the crimping hand tool 100 further includes an elastic member 173 disposed on the first caliper body 110 together with the stopper 172 , and the elastic member 173 is coupled between the body 113 of the first caliper body 110 and the stopper block 172 . Here, the elastic member 173 constantly drives the stopper block 172 to rotate in the counterclockwise direction. The stopper 172 pivotally connected to the first caliper body 110 has a convex portion 172a. When the second caliper body 120 is closed relative to the first caliper body 110, the convex portion 172a is located at the tooth portion 171a of the ratchet structure 171. The moving path is driven, and the relative position of the first caliper body 110 and the second caliper body 120 is fixed by temporarily engaging the convex portion 172a with the tooth portion 171a. At this time, as in the processes of FIGS. 4 to 5, the stopper block 172 is driven to rotate in the clockwise direction, and simultaneously deforms the elastic member 173, that is, the direction in which the elastic member 173 drives the stopper 172 is opposite to the ratchet structure 171. The direction of the stop block 172 is driven. The temporary snapping here refers to that the user can additionally apply a force to release the snap relationship, or re-apply and then snap it. Accordingly, when the first caliper body 110 and the second caliper body 120 are buckled due to an abnormal crimping condition during the crimping process, the user can turn the stopper block 172 and the spine by rotating the stopper block 172. The tooth structures 171 are disengaged from each other to release the snap-fit state.

In addition, the crimping hand tool 100 of the present embodiment further includes a knob 174 disposed outside the first caliper body 110 but passing through the body 113 and connected to the stopping block 172. The knob 174 is convenient for the user to apply force to rotate. In the other embodiments (not shown), the user can also directly drive the stop block 172 without a knob without using a knob.

Next, the housing 300 and the signal line 200 are placed together in the first crimping slot 111, and after being placed, the portion 212 also protrudes out of the first caliper body 110, as shown in FIG. Then, the user applies the pressing portion 121 of the second caliper body 120 to perform the pressure-bonding operation from FIG. 4 to FIG. 5, that is, the second caliper body 120 and the first caliper body 110 are closed relative to each other to The driving linkage 130 rotates in the clockwise direction, and moves in the positive Y-axis direction due to the limitation and guidance of the guiding structure 117, thereby driving the crimping assembly 140 to move in the positive Y-axis direction to enter the first pressure. The groove 111 is connected to generate a state as shown in FIG. 7, that is, the first crimping member 141 crimps the conductive sheet 310 to the core 210 to electrically conduct both. At the same time, the second crimping member 142 also presses the crimping block 314 of the housing 300 to the signal line 200 in synchronization to secure the housing 300 and the signal line 200 (and the core 210) to each other.

While the crimping assembly 140 is moved along the Y axis to allow the first crimping member 141 and the second crimping member 142 to enter the first crimping groove 111, the first cutter 151 attached to the first crimping member 141 is also The portion 212 of the core 210 will be cut away, and the portion of the core 210 that remains within the housing 300 will be aligned with the open end of the housing 300.
