Description

Technical Field

[0001] This utility model relates to the field of transformer conductive bushing technology, specifically a transformer screw output terminal conversion connector. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Transformers are fundamental equipment for power transmission and distribution, widely used in industry, agriculture, transportation, and urban communities. Transformer output connections utilize nuts to secure the output wires to the transformer's conversion connectors. The connecting wires are then fixed to the clamps on the conversion connectors using bolts and nuts. Existing transformer screw output terminal conversion connectors require different clamps when assembling with conductive rods of different specifications, leading to assembly failures due to missing components. Furthermore, the lack of protection for the top of the conductive rod in existing conversion connectors makes the threads at the connection between the rod tip and the mounting sleeve susceptible to rusting from rainwater, hindering later disassembly and maintenance. Utility Model Content

[0003] The purpose of this utility model is to provide a transformer screw output terminal conversion connector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A transformer screw output terminal conversion connector includes a Buddha's Hand clamp with four symmetrically arranged mounting holes. An L-shaped plate is fixedly connected to the bottom of the Buddha's Hand clamp, and a connecting block is fixedly connected to the end of the L-shaped plate. A mounting sleeve is fixedly connected to one side of the connecting block. The mounting sleeve has three mounting cavities with progressively decreasing radii inside. Each of the three mounting cavities has a threaded groove on its periphery. Multiple locking plates are symmetrically fixedly connected to the outer wall of the mounting sleeve, and a clamping slot is provided between two opposite locking plates. A top hole is provided at the center of the top of the mounting sleeve.

[0006] Furthermore, the Buddha's Hand thread clip includes:

[0007] There are two recessed openings, symmetrically located on the outer wall of the Buddha's Hand thread clamp;

[0008] A round shaft seat, rotatably mounted in an inner recess;

[0009] The curved arm is fixedly connected between two round shaft seats;

[0010] The clip is fixedly connected to the end of the curved arm.

[0011] Furthermore, a torsion spring is sleeved on the outside of the round shaft seat, and the torsion spring is fixedly connected to the inner wall of the Buddha's Hand Thread Clamp.

[0012] Furthermore, three anti-slip strips are fixedly connected at equal intervals on the outer wall of the clip.

[0013] Furthermore, a conductive rod is screwed into the mounting cavity, and a mounting nut is screwed onto the outer wall of the conductive rod. A ceramic cap is provided at the bottom of the mounting nut. A ceramic insulator and a ceramic insulator are sleeved on the outside of the conductive rod. A rubber bead abuts between the ceramic insulator and the ceramic cap, and a rubber ring abuts between the ceramic insulator and the ceramic insulator.

[0014] Furthermore, the top of the mounting sleeve is rotatably connected to a rotating seat, a sealing plate is fixedly connected to the side wall of the rotating seat, and a sealing ring that is embedded in the top hole is fixedly connected to the bottom of the sealing plate.

[0015] Furthermore, a bent plate is fixedly connected to the end of the sealing plate, and a sealing gasket that is embedded in the clamping seam is fixedly connected to the inner wall of the bent plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The transformer screw output terminal conversion connector has three mounting cavities with progressively decreasing radii inside the mounting sleeve, and each mounting cavity has a threaded groove on its periphery. This facilitates the installation and connection of various specifications of conductive rods, eliminating the trouble of finding the corresponding clamp for different conductive rods and improving the installation efficiency of the transformer screw and output terminal conversion connector.

[0018] 2. By screwing the conductive rod and the corresponding mounting cavity in the mounting sleeve into place, the closing plate can be rotated to close the top opening of the mounting sleeve, allowing the sealing ring at the bottom of the closing plate to be embedded in the top hole. At the same time, the bending plate is rotated, so that the sealing gasket on the inner wall of the bending plate is embedded and stuck in the clamping gap. Finally, the installation of the conductive rod is reinforced by bolts passing through the locking plate and the bolts working together. This seals the connection between the conductive rod and the mounting sleeve, preventing rainwater from corroding the threaded part at the top of the conductive rod, thus ensuring the conductivity of the conductive rod.

[0019] 3. When connecting the Buddha's Hand clamp and the connector lug of the adapter, first rotate the two clamps outward, then place the connector lug between the two clamps. Then, the bent arm, under the action of the torsion spring, drives the clamps to clamp and position the connector lug. At this time, the bolt can be quickly passed through the mounting hole and the connector lug, reducing the installation pressure on the operator. The operator does not need to use one hand to position the connector lug and the other hand to pass the bolt through for positioning. Then, the nut and bolt are screwed together, and the nut presses the clamp, thereby improving the connection speed between the connector lug and the Buddha's Hand clamp. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 In this embodiment of the present invention, a transformer screw output terminal conversion connector includes a Buddha's Hand clamp 101. The Buddha's Hand clamp 101 has four symmetrically arranged mounting holes 102. An L-shaped plate 109 is fixedly connected to the bottom of the Buddha's Hand clamp 101. A connecting block 110 is fixedly connected to the end of the L-shaped plate 109. An installation sleeve 111 is fixedly connected to one side of the connecting block 110. The installation sleeve 111 has three installation cavities 120 with progressively decreasing radii inside, which facilitates the matching and sleeved installation of conductive rods 201 of various specifications. Threaded grooves are provided on the periphery of the three installation cavities 120. Multiple locking pieces 112 are symmetrically fixedly connected to the outer wall of the installation sleeve 111. A clamping slot 113 is provided between two opposite locking pieces 112. A top hole 114 is provided at the center of the top of the installation sleeve 111.

[0027] Specifically, the installation sleeve 111 of the transformer screw output terminal conversion connector has three mounting cavities 120 with progressively decreasing radii, and each mounting cavity 120 has a threaded groove on its periphery. This facilitates the installation and connection of various specifications of conductive rods 201, thus eliminating the trouble of finding the corresponding Buddha's Hand clamp 101 for different conductive rods 201 and improving the installation efficiency of the transformer screw and output terminal conversion connector.

[0028] Example 1

[0029] like Figure 4 As shown, in this embodiment, a conductive rod 201 is screwed into the mounting cavity 120, and a mounting nut 202 is screwed onto the outer wall of the conductive rod 201. A ceramic cap 203 is provided at the bottom of the mounting nut 202. A ceramic insulator 205 and a ceramic insulator 207 are sleeved on the outside of the conductive rod 201. A rubber bead 204 abuts between the ceramic insulator 205 and the ceramic cap 203, and a rubber ring 206 abuts between the ceramic insulator 205 and the ceramic insulator 207. A rotating seat 115 is rotatably connected to the top of the mounting sleeve 111. A sealing plate 116 is fixedly connected to the side wall of the rotating seat 115, and a sealing ring 118 is fixedly connected to the bottom of the sealing plate 116 and embedded in the top hole 114. This allows the sealing ring 118 at the bottom of the sealing plate 116 to be embedded in the top hole 114. A bent plate 117 is fixedly connected to the end of the sealing plate 116. A sealing gasket 119 that is embedded in the clamping seam 113 is fixedly connected to the inner wall of the bent plate 117. The sealing gasket 119 on the inner wall of the bent plate 117 will be embedded and stuck in the clamping seam 113.

[0030] In this embodiment, after the conductive rod 201 and the corresponding mounting cavity 120 in the mounting sleeve 111 are screwed together, the sealing plate 116 can be rotated to close the top opening of the mounting sleeve 111, so that the sealing ring 118 at the bottom of the sealing plate 116 can be embedded in the top hole 114, and at the same time, the bending plate 117 is rotated, so that the sealing gasket 119 on the inner wall of the bending plate 117 will be embedded and stuck in the clamping gap 113. Finally, the installation of the conductive rod 201 is reinforced by bolts passing through the locking piece 112 and the bolts cooperating. This can seal the connection between the conductive rod 201 and the mounting sleeve 111, prevent rainwater from corroding the top thread of the conductive rod 201, and thus ensure the conductivity of the conductive rod 201.

[0031] Example 2

[0032] like Figure 3As shown, in this embodiment, the Buddha's Hand Thread Clip 101 includes: two recesses 103 symmetrically arranged on the outer wall of the Buddha's Hand Thread Clip 101; a round shaft seat 104 rotatably disposed in the recesses 103; a curved arm 105 fixedly connected between the two round shaft seats 104; and a clamping piece 107 fixedly connected to the end of the curved arm 105. Under the action of a torsion spring 106, the curved arm 105 drives the clamping piece 107 to clamp and position the thread lug. A torsion spring 106 is sleeved on the outside of the round shaft seat 104, and the torsion spring 106 is fixedly connected to the inner wall of the Buddha's Hand Thread Clip 101. Three anti-slip strips 108 are fixedly connected at equal intervals on the outer wall of the clamping piece 107.

[0033] In practice, when connecting the Buddha's Hand clamp 101 of the adapter to the connector lug of the connector, the two clamps 107 can be rotated outward first, and then the connector lug can be placed between the two clamps 107. Then, under the action of the torsion spring 106, the bending arm 105 drives the clamps 107 to clamp and position the connector lug. At this time, the bolt can be quickly passed through the mounting hole 102 and the connector lug, reducing the installation pressure on the operator. The operator does not need to use one hand to position the connector lug and the other hand to use the bolt to pass through and position it. Then, the nut and bolt are screwed together, and the nut presses the clamp 107, thereby improving the connection speed between the connector lug and the Buddha's Hand clamp 101.
