Crimping tool

Abstract

The invention is related to a crimping tool. The crimping tool includes a connection rod having one end pivotally connected to the first handle and the other end of the connection rod pivotally connected to a crimp section. A first screw rod is disposed at the second handle of the crimping tool. The first screw rod drives the connector which leads the first handle to displace. The movement of the first handle leads a connection rod to displace. As a result, the position of a crimp section on the first handle can be adjusted.

(67) As shown, a coaxial cable 200 and a coaxial plug 300 crimped together by the crimping tool 100 to form a single unit. The crimping tool 100 comprises a first handle 10, a first through hole 11s disposed at the first handle 10; a second handle 20, a first guide section 21, a second guide section 22, a third guide section 23 and a fourth guide section 24 disposed at the second handle 20, the second handle front section 251 being a hollow structure 251A, an adjustment part 30 disposed in the hollow structure 251A, a second through hole 32 disposed at the adjustment part 30, a connection rod 40 having one end pivotally connected to the first handle 10 and the other end of the connection rod 40 pivotally connected to a crimp section 50, one end of the crimp section 281 disposed in the third guide section 23, the other end of the crimp section 282 disposed in the fourth guide section 24, the third guide section 23 and the fourth guide section 24 served as displacement rails for the crimp section 50, a first screw hole 61 disposed at a connector 60, the first guide section 21 initially disposed in the connector 60 and then passing through one end of the adjustment part 30, the first through hole 11, and the other end of the adjustment part 30 prior to placing inside the second guide section 22, the connector 60 pivotally connected to the first handle 10 and the second handle 20, the first guide section 21 and the second guide section 22 served as displacement guide for the connector 60; a first screw rod 71 initially passing through the second through hole 32 and screwed into the first screw hole 61, the rotation of the first screw rod 71 driving the connector 60 to displace, the connector 60 then driving the first handle 10 to displace, the first handle 10 then driving the connection rod 40 to displace, thereby adjusting the location of the crimp section 50.

(68) Moreover, a first linkage rod 19 is disposed at the first handle 10, one end of a first recovery spring 81 is connected to the first linkage rod 19, and the other end of the first recovery spring 81 is connected to the connection rod 40.

(69) Moreover, a crimp head 51 is disposed at the crimp section 50. Therefore, the crimp head 51 is utilized during crimping operation.

(70) Moreover, a hollow support block 252A is disposed at rear end of the second handle 252. Hence, a hollow support block 252A is served as support while crimping is in progress. A coaxial cable 200 can pass through the center void of the hollow support block 252A.

(71) Moreover, a second screw rod 72 is disposed at the crimp head 51, a second screw hole 62 is disposed at the crimp section 50, and the second screw rod 72 screws into the second screw hole 62. The rotation of the second screw rod 72 adjusts the depth of the second screw rod 72 while being in the second screw hole 62, thereby achieving the position adjustment of the crimp head 51. Therefore, the depth of the second screw rod 72 is adjusted while being inside the second screw hole 62 by rotating the second screw rod 72. As a result, the location of the crimp head 51 is adjusted. Various positions of the crimp head 51 mean that crimping operation can perform against coaxial plug and coaxial cable of various specifications.

(72) Moreover, a first holding block 91 is pivotally connected to rear end of the second handle 252, a second holding block 92 is pivotally connected to rear end of the second handle 252, the first holding block 91 is disposed next to the second holding block 92, and the first holding block 91 and the second holding block 92 form an annular run through placement space 93. Hence, both the first holding block 91 and the second holding block 92 are served as support during crimping. A coaxial cable 200 can be placed within the annular run through placement space 93. The coaxial cable 200 will not have any random movement while the crimping tool 100 performs crimping operation. Therefore, the quality of crimp join made by the crimping tool 100 is increased.

(73) Moreover, a first holding block 91 is disposed at rear end of the second handle 252, a second holding block 92 is pivotally connected to rear end of the second handle 252, the first holding block 91 is disposed next to the second holding block 92, the first holding block 91 and the second holding block 92 together form an annular run through placement space 93; one end of the second recovery spring 82 is connected to the first holding block 91, and the other end of the second recovery spring 82 is connected to the second holding block 92. Hence, both the first holding block 91 and the second holding block 92 are served as support during crimping.

(74) A coaxial cable 200 can be placed within the annular run through placement space 93. Rotating the first holding block 91 and the second holding block 92 can place the coaxial cable 200. After loosening and rotating, the second recovery spring 82 will cause the first holding block 91 to restore to its original position, and the second holding block 92 will also restore to its original position. During crimping operation by using the crimping tool 100, the coaxial cable will not have any random movement. Therefore, the invention can increase the quality of crimp joining a coaxial cable.

(75) Moreover, a first holding block 91 is pivotally connected to rear end of the second handle 252, a protruding piece 911 is disposed at the first holding block 91, a second holding block 92 is pivotally disposed at rear end of the second handle 252, a notch 921 is disposed at the second holding block 92, and the protruding piece 911 is disposed in the notch 921; and a third recovery spring 83 is placed on top of the second handle 20 and pushes against the first holding block 91. Hence, both the first holding block 91 and the second holding block 92 are served as support while crimping is in progress. A coaxial cable 200 can be placed within the annular run through placement space 93. Applying a rotational force causes the first holding block 91 to press downward against the third recovery spring 83. After releasing the rotational force, the third recovery spring 83 restores to its original position to push the first holding block 91 so that the first holding block 91 can restore to its original position. The protruding piece 911 will push the notch 921 to rotate so that the second holding block 92 is driven to rotate and restore to its original position. The coaxial cable 200 will not have any random movement while the crimping tool 100 performs crimping operation. Therefore, the quality of crimp made by the crimping tool 100 is increased.

(76) While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
