[0030] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0031] The technical solution of the present invention is further described below in conjunction with embodiments and drawings.

[0032] like Figure 1 , 2 As shown in FIG. 3 , a wedge block installation device for a tension clamp according to an embodiment of the present invention is used to fix an insulated conductor on a tension clamp 5. The tension clamp 5 includes a clamp body 51 and a wedge block 52 inserted into the clamp body 51, including:

[0033] The housing 1 has a fixing cavity 111 and an installation cavity 121. The fixing cavity 111 and the installation cavity 121 are connected to each other. The fixing cavity 111 is used to fix the wire clamp body 51.

[0034] The push assembly 2 includes a driving part 21 and a push block 22. The push block 22 is disposed in the installation cavity 121. The power output end of the driving part 21 is connected to the push block 22 to drive the push block 22 to slide in the installation cavity 121. The push block 22 is used to abut against the wedge block 52 and push the wedge block 52 into the wire clamp body 51. A clearance hole 221 is provided on the push block 22. The clearance hole 221 is used for the insulated wire to pass through.

[0035] The pressure sensor 3 is electrically connected to the push block 22 and is used to detect the pressure applied by the push block 22 to the wedge block 52 .

[0036] Based on the above technical solution, the fixing cavity 111 fixes the wire clamp body 51, and the installation cavity 121 contains the wedge block 52. The driving unit 21 drives the push block 22 to push the wedge block 52 into the wire clamp body 51. Since the push block 22 is electrically connected to the pressure sensor 3, the pressure sensor 3 can provide real-time feedback on the pressure applied by the push block 22 to the wedge block 52. When the pressure value fed back by the pressure sensor 3 reaches a preset value, the tension clamp 5 can be removed. At this time, the installation of the wire clamp body 51 and the wedge block 52 is completed. The force is applied accurately and the consistency of the installation can be guaranteed each time. It can prevent the wire clamp body 51 from being crushed and the wedge block 52 from loosening during subsequent use.

[0037] Preferably, the housing 1 includes a first shell 11 and a second shell 12 that are detachably connected, the first shell 11 and the second shell 12 are arranged in the front-to-back direction, the fixing cavity 111 is arranged in the first shell 11, the installation cavity 121 is arranged in the second shell 12, and a position adjustment component 4 is arranged between the first shell 11 and the second shell 12, and the position adjustment component 4 is used to connect and adjust the distance between the first shell 11 and the second shell 12. The first shell 11 and the second shell 12 are detachably arranged through the position adjustment component 4, which can adjust the distance between the first shell 11 and the second shell 12 to adapt to different lengths of the tension clamp 5 and meet different installation requirements.

[0038] In a specific embodiment, two positioning components 4 are provided between the first shell 11 and the second shell 12, and the two positioning components 4 are respectively located on both sides in the front-to-back direction. When the tension clamp 5 with a larger overall size is installed, a relatively stable structural relationship can still be ensured between the first shell 11 and the second shell 12.

[0039] More preferably, the positioning assembly 4 includes a connecting strip 41 and a plurality of positioning blocks 42, the connecting strip 41 is hinged on the first housing 11, a plurality of positioning holes 411 are arranged at intervals along the extension direction of the connecting strip 41, a plurality of positioning blocks 42 are arranged at intervals along the front-back direction on the second housing 12, and the positioning holes 411 are matched and plugged with the positioning blocks 42 in a one-to-one correspondence. The connecting strip 41 is hinged on the first housing 11, and the matching and plugging of the positioning blocks 42 and the positioning holes 411 can be completed by simply rotating the connecting strip 41, and the number of matching and plugging adjusting holes 411 and adjusting blocks 42 is reasonably selected to adapt to the specific size of the tension clamp 5.

[0040] More preferably, the adjustment hole 411 is a waist-shaped hole, and the extension direction of the waist-shaped hole is parallel to the extension direction of the connecting strip 41. The adjustment hole 411 is set as a waist-shaped hole, which increases the flexibility of installing the wire clamp body 51 and the wedge block 52 to a certain extent. After the wire clamp body 51 is installed in the fixing cavity 111, there is still a certain degree of mobility between the first shell 11 and the second shell 12, which is convenient for installing and placing the wedge block 52 in the installation cavity 121. Before installation, the position relationship between the wedge block 52 and the wire clamp body 51 can be better adjusted to meet the installation requirements.

[0041] More preferably, the driving part 21 includes a screw rod 211, a connecting rod 214 and a hand wheel 215. The screw rod 211 is rotatably arranged in the installation cavity 121 along the front-to-back direction. The end of the screw rod 211 away from the fixed cavity 111 is provided with a first right-angle gear 212. The connecting rod 214 extends along the up-down direction and is rotatably arranged on the second shell 12. The lower end of the connecting rod 214 passes through the second shell 12. The lower end of the connecting rod 214 is provided with a second right-angle gear 213. The first right-angle gear 212 is meshed with the second right-angle gear 213. The upper end of the connecting rod 214 is connected to the hand wheel 215. The push block 22 is provided with a threaded hole, and the screw rod 211 is meshed with the threaded hole.

[0042] Specifically, the user rotates the hand wheel 215 to drive the second right-angle gear 213 to rotate, and the rotation of the second right-angle gear 213 drives the first right-angle gear 212 to rotate, and drives the screw rod 211 to rotate, thereby achieving the sliding of the push block 22 in the installation cavity 121 along the extension direction of the screw rod 211.

[0043] The push block 22 will not slide when subjected to the pressure of the wedge block 52, thereby ensuring the stability of the force applied to the wedge block 52. The pressure sensor 3 is electrically connected to the push block 22, and the sliding of the push block 22 is converted by the rotation of the hand. When the hand wheel 215 is turned, the pressure feedback of the pressure sensor 3 changes little, thereby achieving precise force application.

[0044] More preferably, the push assembly 2 further includes a guide block 23, which is fixedly disposed in the installation cavity 121 and located in front of the push block 22. The guide block 23 is provided with a guide hole 231, which is provided along the front-rear direction. The guide hole 231 is provided on the guide block 23 to ensure that the wedge block 52 can be aligned with the access port of the wire clamp body 51 along the guide hole 231, to ensure the consistency of the installation, and to avoid the phenomenon that the wedge block 52 contacts the inner wall of the wire clamp body 51 in advance. If the above phenomenon occurs, the pressure fed back to the pressure sensor 3 is not the pressure during the correct installation, and the installation is wrong.

[0045] More preferably, the push assembly 2 further includes two guide rods 24, which are respectively arranged in the installation cavity 121 and located on both sides of the screw rod 211. The two guide rods 24 extend in the front-rear direction, and the two guide rods 24 pass through the push block 22, and the push block 22 can slide relative to the guide rods 24. The guide rods 24 are arranged to ensure that the contact surface between the push block 22 and the wedge block 52 can remain straight, so as to avoid the push block 22 from tilting after multiple uses, so that the pressure measured by the pressure sensor 3 is inaccurate, and the installation consistency is difficult to ensure.

[0046] More preferably, a first opening 112 is formed at the bottom of the first shell 11 , a second opening 122 is formed at the bottom of the second shell 12 , the first opening 112 is connected to the fixing cavity 111 , the second opening 122 is connected to the installation cavity 121 , and the first opening 112 is connected to the second opening 122 .

[0047] Specifically, the wire clamp body 51 is installed from bottom to top in the fixing cavity 111 through the first opening 112, and the wedge block 52 is installed in the installation cavity 121 through the second opening 122. Then, the hand wheel 215 is turned to drive the push block 22 to slide, pushing the wedge block 52 into the wire clamp body 51. If it is visually observed that the installation is not aligned, the wire clamp body 51 and the wedge block 52 can be directly removed from the first opening 112 and the second opening 122 and reinstalled. The operation is convenient and quick.

[0048] More preferably, the pressure sensor 3 is installed in the installation cavity 121 and is located on the side away from the fixing cavity 111. A display screen 31 is provided on the second housing 12, and the pressure sensor 3 is electrically connected to the display screen 31. Through the display screen 31, it is possible to directly observe how much pressure the push block 22 applies to the wedge block 52 at this time, and if the preset pressure value is met, the tension clamp 5 can be directly removed.

[0049] Preferably, the inner wall of the fixing cavity 111 matches the shape of the wire clamp body 51. The wire clamp body 51 can be installed by directly placing it in the fixing cavity 111 without unnecessary displacement due to the pressure of the wedge block 52.

[0050] In summary, an embodiment of the present invention provides a wedge block installation device for a tension clamp, wherein a fixing cavity 111 fixes a clamp body 51, and a wedge block 52 is placed in an installation cavity 121; a driving unit 21 drives a push block 22 to push the wedge block 52 into the clamp body 51, and since the push block 22 is electrically connected to the pressure sensor 3, the pressure sensor 3 can provide real-time feedback of the pressure applied by the push block 22 to the wedge block 52. When the pressure value fed back by the pressure sensor 3 reaches a preset value, the tension clamp 5 can be removed, and at this time, the installation of the clamp body 51 and the wedge block 52 is completed. The force is applied accurately and the consistency of the installation can be guaranteed each time. This can prevent the clamp body 51 from being crushed, and can also prevent the wedge block 52 from loosening during subsequent use.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
