DETAILED DESCRIPTION

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0041] Example 1:

[0042] like Figure 1 and Figure 2 As shown, this embodiment provides a press-type wire clamp, including a first terminal 1, a pressing assembly 2, a reset assembly 3, a second terminal 4, a connector 5, a guide block 6, a third terminal 7, an insulator connector 8, an insulator 9, a clamp 10 and an insulating shield 11.

[0043] like Figure 3As shown, the first terminal block 1 includes a first contact 101, a first terminal 104 connected to the first contact 101, and a first wiring hole 105 provided on the first terminal 104; a conical boss 102 and a first circular boss 103 are provided between the first contact 101 and the first terminal 104. It is understood that the first wiring hole 105 is used to connect a wire, and the wire end can be fixed in the first wiring hole 105 by means of crimping or other methods.

[0044] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, there are two pressing components 2 symmetrically arranged, and each pressing component 2 includes a first guide hole 202, a second guide hole 203 connected to the first guide hole 202, and a first annular limiting groove 205 connected to the second guide hole 203; a rotating shaft mounting hole 201 is opened at the position of the second guide hole 203, and a trapezoidal platform 204 is arranged between the second guide hole 203 and the first annular limiting groove 205.

[0045] It is understandable that when the first terminal 1 is installed, the first contact 101 end of the first terminal 1 is passed through the first guide hole 202 and the second guide hole 203. Before the conical boss 102 and the first circular boss 103 reach the first annular limiting groove 205, the conical boss 102 and the first circular boss 103 separate the two pressing assemblies 2. After the first circular boss 103 engages with the first annular limiting groove 205, the two pressing assemblies 2 are reset and closed under the action of the reset assembly 3. The first guide hole 202 is an arc-shaped opening. When the conical boss 102 passes through the first guide hole 202, the second guide hole 203, and the conical boss 102 in sequence, the first guide hole 202 and the conical boss 102 cooperate, resulting in fast guidance and simple operation.

[0046] like Figure 1 and Figure 6 As shown, the reset assembly 3 includes a rotating shaft 301 and an elastic reset member 302 provided on the rotating shaft 301 ; the rotating shaft 301 is vertically fixed on the splint 10 .

[0047] It can be understood that the rotating shaft 301 is sleeved in the rotating shaft mounting hole 201, and the two ends of the elastic reset member 302 are respectively connected to the pressing assembly 2 and the clamping plate 10; when the first terminal 1 separates the two pressing assemblies 2, the elastic reset member 302 stores energy, and when the first circular boss 103 is engaged with the first annular limiting groove 205, the two pressing assemblies 2 are reset and closed under the action of the elastic reset member 302. Similarly, when it is necessary to remove the first terminal 1, the two pressing assemblies 2 are pressed, and the two pressing assemblies 2 are separated. The elastic reset member 302 stores energy, and after the first terminal 1 is taken out, the pressing is stopped. Under the action of the elastic reset member 302, the two pressing assemblies 2 are reset and closed. The first terminal 1 is easy to install and disassemble, and the engagement of the first circular boss 103 with the first annular limiting groove 205 ensures the stability of the connection.

[0048] like Figure 7 As shown, the second terminal block 4 includes a second contact 401, a second terminal block 403 connected to the second contact 401, and a second connection hole 404 defined in the second terminal block 403. A second circular boss 402 is provided between the second contact 401 and the second terminal block 403. It will be appreciated that the second connection hole 404 is used to connect a wire, and the lead wire end can be secured within the second connection hole 404 by crimping or other means. The structure and disassembly method of the third terminal block 7 are identical to those of the second terminal block 4 and will not be further described here.

[0049] like Figure 8 and Figure 9 As shown, the connector 5 includes a through hole 501, an internal thread 502 disposed within the through hole 501, and a second annular retaining groove 503. As will be appreciated, the connector 5 is connected to the guide block 6 via the internal thread 502; the second annular retaining groove 503 engages the second circular boss 402 to secure the second terminal 4 to the guide block 6. The process and method for securing the third terminal 7 to the guide block 6 are the same as for the second terminal 4 and will not be further described here.

[0050] like Figure 10As shown, the guide block 6 includes a first contact connection hole 601, and a second contact connection hole 604 and a third contact connection hole 607 located at both ends of the first contact connection hole 601 and axially perpendicular to the first contact connection hole 601; a first spring contact finger group 602 and a second spring contact finger group 605 are respectively provided in the first contact connection hole 601, the second contact connection hole 604 and the third contact connection hole 607; a conical limiting groove 603 is provided at the entrance position of the first contact connection hole 601; the outside of the second contact connection hole 604 and the third contact connection hole 607 are both provided with external threads 606.

[0051] It can be understood that the first contact 101 achieves electrical connection after entering the first contact connection hole 601, and the cooperation between the first spring contact finger group 602 and the first contact 101 ensures the stability of the electrical connection; the conical boss 102 is engaged in the conical limiting groove 603, further improving the stability.

[0052] The second contact 401 enters the second contact connection hole 604 to establish electrical connection. The second spring contact finger group 605 cooperates with the second contact 401 to ensure the stability of the electrical connection. The external thread 606 cooperates with the internal thread 502 to secure the connector 5 to the guide block 6. Similarly, the connection between the third terminal 7 and the third contact connection hole 607 is similar to the connection between the second terminal 4 and the second contact connection hole 604, and will not be described in detail here.

[0053] The first contact 101 and the second contact 401 are both provided with a cold shrink tubing 12 . After the first contact 101 and the second contact 401 are installed, the cold shrink tubing 12 is wrapped around the outside to play an insulating role.

[0054] like Figure 11 and Figure 12 As shown, the insulator connector 8 includes a first insulator connecting plate 801 and a second insulator connecting plate 802; both the first insulator connecting plate 801 and the second insulator connecting plate 802 are provided with fixing holes 803 and insulator connection holes 804. As will be understood, the fixing holes 803 cooperate with bolts or the like to secure the insulator connector 8 to the clamping plate 10. The two insulator connection holes 804 are adapted to subsequently connect with the insulator 9, ensuring flexibility and ease of operation during the connection process while also ensuring a stable connection to the insulator. The insulator 9 is mounted on the hanging point to provide insulation and maintain a certain electrical distance between the clamp and the tower.

[0055] like Figure 13As shown, the clamping plate 10 includes a clamping plate body 1001, and a shaft fixing hole 1002, a first bolt fixing hole 1003, a second bolt fixing hole 1004, a third bolt fixing hole 1005, and a fourth bolt fixing hole 1006 provided on the clamping plate body 1001. It is understood that the shaft 301 is fixed to the shaft fixing hole 1002 by welding or bolting; the guide block 6 is fixed to the clamping plate 10 via the first bolt fixing hole 1003, the second bolt fixing hole 1004, and bolts; and the insulator connector 8 is fixed to the clamping plate 10 via the third bolt fixing hole 1005, the fourth bolt fixing hole 1006, and bolts.

[0056] Specifically, two mutually parallel clamping plates 10 are provided, and the pressing assembly 2, the resetting assembly 3, the connecting piece 5, the guide block 6 and the insulator connecting piece 8 are arranged between the two clamping plates 10. The installation direction of the first terminal 1 is perpendicular to the installation direction of the second terminal 4, and the resetting assembly 3 and the insulator connecting piece 8 are located at both ends of the guide block 6, and the connecting piece 5 is located on the side of the guide block 6; the pressing assembly 2, the resetting assembly 3, the connecting piece 5, the guide block 6 and the insulator connecting piece 8 between the first terminal 1 and the insulator are closely distributed, which is conducive to on-site construction and maintenance work, and the first terminal 1 and the second terminal 4 are detachably arranged on the guide block 6 through the resetting assembly 3 and the connecting piece 5 respectively, which reduces the construction difficulty and improves the construction efficiency;

[0057] like Figure 14 As shown, the insulating shield 11 wraps around the entire wire clamp to ensure overall insulation. The insulating shield 11 includes a shield body 1101, a shaft accommodating chamber 1102, a first bolt accommodating chamber 1103, a second bolt accommodating chamber 1104, a third bolt accommodating chamber 1105, and a fourth bolt accommodating chamber 1106 provided in the shield body 1101, a first terminal through-hole 1107 and an insulator through-hole 1108 provided at both ends of the shield body 1101, and a second terminal through-hole 1109 provided in the middle of the shield body 1101. It can be understood that the shaft accommodating chamber 1102 is used to accommodate the two ends of the shaft 301, and the first bolt accommodating chamber 1103, the second bolt accommodating chamber 1104, the third bolt accommodating chamber 1105, and the fourth bolt accommodating chamber 1106 are respectively used to accommodate the two ends of the corresponding bolts.

[0058] This embodiment adopts an integral insulation form with its own insulators to ensure sufficient electrical distance; on-site construction only requires crimping the first terminal 1 and the second terminal 4, which greatly improves on-site operation efficiency; the end portion can be connected to the tower hanging point with a U-shaped structure, which is suitable for corner towers of various angles and meets the needs of multiple working conditions; the combination of bosses and limit slots is more reliable than traditional bolt-type and wedge-shaped tension clamps.

[0059] Example 2:

[0060] This embodiment provides a method for using a push-type wire clamp, using the push-type wire clamp as described in Example 1, including: connecting the first terminal 1 and the second terminal 4 to the wire and the lead respectively, and connecting the insulator connector 8 to the insulator; connecting the first terminal 1 and the second terminal 4 to the guide block 6 through the reset assembly 3 and the connector 5 respectively.

[0061] The above description is merely a preferred embodiment of this embodiment and is not intended to limit this embodiment. Those skilled in the art will readily appreciate that this embodiment may be modified and varied in various ways. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this embodiment shall be within the scope of protection of this embodiment.
