DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings. Example

[0024] like Figure 1-8 As shown, a quick-install crimping power connection device comprises an electric energy meter mounting plate 1, wherein an installation cavity 2 is arranged inside the electric energy meter mounting plate 1, a lifting and lowering crimping and tightening mechanism 3 is arranged above the installation cavity 2, a rubber block 4 is arranged below the lifting and lowering crimping and tightening mechanism 3, the lifting and lowering crimping and tightening mechanism 3 contacts the electric energy meter through the rubber block 4, and realizes the mobile crimping and adjusting function of the electric energy meter; a horizontal plate 5 is arranged below the installation cavity 2, a plurality of springs 6 are evenly spaced from left to right inside the horizontal plate 5, conductive columns 7 are arranged inside the springs 6, an electric connection socket 8 is arranged below the horizontal plate 5, and electric wires 9 corresponding to the conductive columns 7 are arranged below the electric connection socket 8.

[0025] The lifting, pressing and tightening mechanism 3 includes a base plate 31, a base 32 is arranged on the bottom surface of the base plate 31, a cylinder 33 is installed on the base 32, and a plurality of lifting and adjusting mechanisms 34 are evenly spaced on one side of the cylinder 33. The lifting and adjusting mechanisms 34 close to the cylinder 33 are connected to the cylinder 33 through a first floating joint 35, and the lifting and adjusting mechanisms 34 are connected by a second floating joint 36.

[0026] The cylinder 33 is a MSCFA20-30 small cylinder; the first floating joint 35 is a FJCXS6-1.0 external thread installation type joint; the second floating joint 36 is a FJMW4-0.7 T-slot support type joint.

[0027] The lifting and lowering adjustment mechanism 34 includes a group of fixed seats 41 installed on the base plate 31, and the fixed seats 41 are connected by a first rack rod 42. A follower roller 43 is arranged above the first rack rod 42, and the follower roller 43 is installed on a bearing seat 44 with a bracket.

[0028] The first rack rod 42 is movably connected to the fixed seat 41 by a dry bushing, and the first rack rods 42 are connected by a second floating joint 36; the bearing seat 44 with a bracket is a CMFLSF12-54 type bearing seat.

[0029] A first spur gear 45 is meshed with the first rack rod 42 below, a guide shaft support 46 is provided at one side of the first spur gear 45 , and the first spur gear 45 penetrates the guide shaft support 46 and is axially connected to a second spur gear 47 .

[0030] A T-shaped fixing rod sleeve 48 is provided on one side of the guide shaft support 46, and a lifting plate 49 connected to the rubber block 4 is provided below the T-shaped fixing rod sleeve 48. An opening 401 is provided on the T-shaped fixing rod sleeve 48 corresponding to the second spur gear 47.

[0031] In this embodiment, the working principle of the lifting and pressing mechanism is as follows: the cylinder drives the first rack rod to slide in the fixed seat through the first floating joint, and the first rack rods are linked through the second floating joint, so that the cylinder can synchronously drive the multiple first rack rods to move, and the follower roller ensures the stable and reliable movement of the first rack rod, and can also ensure that the first rack rod is always meshed with the first spur gear. Therefore, when the first rack rod moves, it will drive the first spur gear to rotate. Since the first spur gear is connected to the second spur gear shaft, it will drive the second spur gear to rotate, and finally the second spur gear drives the second gear The bar moves up and down, and the second rack bar will drive the lifting plate to move, so the rubber block and the electric energy meter can be driven to move through the lifting plate, so as to achieve stable and reliable connection between the wires and the internal lines of the electric energy meter. It is convenient and quick to use, and there is no need to manually press the electric energy meter up and down and then fix the electric energy meter. Only the lifting and lowering pressing and tightening mechanism can realize the two functions of pressing down and fixing the electric energy meter. There is no need for a force to continuously press down the electric energy meter and then fix the electric energy meter, which frees both hands, greatly shortens the wiring, reduces the workload of the staff, and can also ensure that the electric energy meter is effectively connected to the line.

[0032] The present invention is a quick-installed crimping type power connection device. In use, the electric energy meter is placed in the installation cavity 2 of the present invention, and then the electric energy meter is pressed upward and downward by the lifting and lowering crimping and tightening mechanism 3. During the downward movement of the electric energy meter, the conductive column 7 is driven to move downward inside the horizontal plate 5, so that the conductive column 7 moves down to the power connection seat 8, and enters the connector 83 inside the shell 81 through the limit spring through hole 82 of the power connection seat 8, so that the conductive column 7 contacts with the crimping terminal 301, and as the lifting and lowering crimping and tightening mechanism 3 continues to drive the electric energy meter to move downward, the conductive column 7 is moved downward to the power connection seat 8. The electric post 7 is tightly connected with the crimping terminal 301, and the lifting and lowering crimping and clamping mechanism 3 always exerts a downward force on the electric energy meter, so that the electric energy meter and the conductive post 7 are stably connected with the crimping terminal 301, and the electric wire 9 is stably and reliably connected with the internal circuit of the electric energy meter, saving wiring time and reducing the labor of the staff. It is not easy to loosen during long-term use, thereby ensuring the normal operation of the electric energy meter. The present invention has the advantages of reasonable structure, convenient and quick installation, ensuring good contact at all times, and ensuring the normal operation of the electric energy meter. Example

[0033] like Figure 1-8 As shown, a quick-install crimping power connection device comprises an electric energy meter mounting plate 1, wherein an installation cavity 2 is arranged inside the electric energy meter mounting plate 1, a lifting and lowering crimping and tightening mechanism 3 is arranged above the installation cavity 2, a rubber block 4 is arranged below the lifting and lowering crimping and tightening mechanism 3, the lifting and lowering crimping and tightening mechanism 3 contacts the electric energy meter through the rubber block 4, and realizes the mobile crimping and adjusting function of the electric energy meter; a horizontal plate 5 is arranged below the installation cavity 2, a plurality of springs 6 are evenly spaced from left to right inside the horizontal plate 5, conductive columns 7 are arranged inside the springs 6, an electric connection socket 8 is arranged below the horizontal plate 5, and electric wires 9 corresponding to the conductive columns 7 are arranged below the electric connection socket 8.

[0034] The power socket 8 includes a shell 81 , and a plurality of limit spring through holes 82 are evenly spaced from left to right above the shell 81 . Connectors 83 corresponding to the limit spring through holes 82 are arranged inside the shell 81 .

[0035] The connector 83 includes a crimping terminal 301, and a group of mounting protrusions 302 that are snap-connected to the shell 81 are arranged in front of the crimping terminal 301, a first crimping spring piece 303 is arranged above the crimping terminal 301, and a second crimping spring piece 304 is arranged above the first crimping spring piece 303; a crimping head 305 is arranged below the crimping terminal 301.

[0036] In this embodiment, the first crimping spring sheet and the second crimping spring sheet are sequentially arranged on the crimping terminal of the connector. The crimping spring sheets can be deformed, so the conductive column can be smoothly inserted into the first crimping spring sheet and the second crimping spring sheet of the crimping terminal from top to bottom (the limiting spring through hole on the shell limits the spring outside the conductive column to ensure that only the conductive column is allowed to enter the shell through the limiting spring through hole). When the conductive column completely enters the connector, the crimping spring sheet cooperates with the shell to form a contact with the conductive column, thereby stably and fixedly connecting the conductive column and the crimping terminal in the shell. The connection method is very simple.

[0037] The present invention is a quick-installed crimping type power connection device. In use, the electric energy meter is placed in the installation cavity 2 of the present invention, and then the electric energy meter is pressed upward and downward by the lifting and lowering crimping and tightening mechanism 3. During the downward movement of the electric energy meter, the conductive column 7 is driven to move downward inside the horizontal plate 5, so that the conductive column 7 moves down to the power connection seat 8, and enters the connector 83 inside the shell 81 through the limit spring through hole 82 of the power connection seat 8, so that the conductive column 7 contacts with the crimping terminal 301, and as the lifting and lowering crimping and tightening mechanism 3 continues to drive the electric energy meter to move downward, the conductive column 7 is moved downward to the power connection seat 8. The electric post 7 is tightly connected with the crimping terminal 301, and the lifting and lowering crimping and clamping mechanism 3 always exerts a downward force on the electric energy meter, so that the electric energy meter and the conductive post 7 are stably connected with the crimping terminal 301, and the electric wire 9 is stably and reliably connected with the internal circuit of the electric energy meter, saving wiring time and reducing the labor of the staff. It is not easy to loosen during long-term use, thereby ensuring the normal operation of the electric energy meter. The present invention has the advantages of reasonable structure, convenient and quick installation, ensuring good contact at all times, and ensuring the normal operation of the electric energy meter.
