Description

Technical Field

[0001] This utility model relates to the field of terminal crimping technology, and more specifically to a terminal connection device. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. In industry, they are classified as connectors. When connecting terminal blocks to wires, terminal crimping devices are required. Currently, common terminal crimping devices include hydraulic crimping pliers.

[0003] Hydraulic crimping pliers typically consist of a jaw, several pairs of dies of different diameters, and a limiting rod. Removing the limiting rod allows for the replacement of dies of different diameters. Currently, the limiting rod is mostly connected to the jaw via pins or nuts. These parts are small and separate from the limiting rod, making them prone to loss in complex construction environments, affecting subsequent use. Therefore, there is an urgent need to design a terminal block connection device to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a terminal block connection device to solve the problem that the connection between the limit rod and the clamping jaw in the prior art is mostly through pins or nuts, etc. These parts are small in size and are separate from the limit rod, and are easily lost in the complex construction site after being removed.

[0005] The present invention provides the following technical solution: a terminal block connection device, including a hydraulic clamp body, and further including a plug-in component and a locking component, wherein the plug-in component is slidably plugged into the hydraulic clamp body, and the locking component is slidably plugged into the plug-in component;

[0006] The insertion assembly includes a hollow cylinder that is slidably inserted into the hydraulic clamp body. The locking assembly includes a slide rod and two locking rods. The slide rod is slidably inserted into the hollow cylinder, and the two locking rods are slidably installed inside the slide rod, with both locking rods penetrating through the hollow cylinder.

[0007] Furthermore, the outer wall of the hydraulic clamp body is provided with a through hole, and the hollow cylinder is slidably inserted into the through hole.

[0008] Furthermore, the plug-in assembly also includes two clamping plates, which are symmetrically fixedly installed on the outer wall of the hollow cylinder. The outer wall of the hydraulic clamp body has two slots, and the clamping plates are adapted to the slots.

[0009] Furthermore, the locking assembly also includes a rotating rod and two limiting blocks. The rotating rod is rotatably mounted on the top of the sliding rod, and the two limiting blocks are symmetrically fixedly mounted on the outer wall of the rotating rod. The outer wall of the hollow cylinder has two L-shaped grooves, and the limiting blocks are adapted to the L-shaped grooves.

[0010] Furthermore, the plug-in assembly also includes two ear plates and two springs. The two ear plates are symmetrically fixedly installed on the inner wall of the hollow cylinder, and one end of each of the two springs is fixedly installed on the top of the two ear plates. The outer wall of the slide rod has two vertical grooves symmetrically opened, and the other ends of the two springs are fixedly installed on the top inner wall of the two vertical grooves.

[0011] Furthermore, the outer wall of the slide bar has two symmetrically formed inclined grooves, and the two locking rods are slidably installed in the two inclined grooves respectively. The inner wall of the two inclined grooves is provided with a sliding groove. The end of the locking rod that is in contact with the inclined groove is fixedly installed with a first slider, which is slidably installed in the sliding groove.

[0012] Furthermore, a second slider is fixedly installed on both sides of the first slider, and a strip groove is opened on both sides of the inner wall of the slide groove, and the second slider is slidably installed in the strip groove.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention, through its plug-in and locking components, allows workers to easily remove the hollow cylinder and slide rod. Simply rotate the rotating rod to align the limiting block with the L-shaped groove, then press the rotating rod downwards to slide the slide rod down, causing the two locking rods to slide into the inclined groove, thus unlocking the hollow cylinder and slide rod. To install the hollow cylinder and slide rod, simply insert the hollow cylinder into the through hole, allowing the locking plate to engage with the slot. Then, rotate the rotating rod to disengage the limiting block from the L-shaped groove. The two springs will release and push the slide rod upwards, causing the two locking rods to slide out again, thus limiting and fixing the hollow cylinder and slide rod. The two locking rods in this device are slidably mounted inside the slide rod and do not need to be separated from it during disassembly and installation, preventing loss.

[0027] The insertion assembly 2 includes a hollow cylinder 201, which is slidably inserted into the hydraulic clamp body 1. The locking assembly 3 includes a slide rod 301 and two locking rods 306. The slide rod 301 is slidably inserted into the hollow cylinder 201, and the two locking rods 306 are slidably installed in the slide rod 301, and both locking rods 306 penetrate the hollow cylinder 201.

[0028] Specifically, the outer wall of the hydraulic clamp body 1 has a through hole 4, and the hollow cylinder 201 is slidably inserted into the through hole 4.

[0029] Specifically, the plug-in assembly 2 also includes two clamping plates 202, which are symmetrically fixedly installed on the outer wall of the hollow cylinder 201. The outer wall of the hydraulic clamp body 1 has two slots 5, and the clamping plates 202 are adapted to the slots 5.

[0030] Specifically, the locking assembly 3 also includes a rotating rod 302 and two limiting blocks 303. The rotating rod 302 is rotatably mounted on the top of the slide rod 301, and the two limiting blocks 303 are symmetrically fixedly mounted on the outer wall of the rotating rod 302. Two L-shaped grooves 203 are opened on the outer wall of the hollow cylinder 201, and the limiting blocks 303 are adapted to the L-shaped grooves 203.

[0031] Specifically, the plug-in assembly 2 also includes two ear plates 204 and two springs 205. The two ear plates 204 are symmetrically fixedly installed on the inner wall of the hollow cylinder 201. One end of each of the two springs 205 is fixedly installed on the top of the two ear plates 204. Two vertical grooves 304 are symmetrically opened on the outer wall of the slide rod 301. The other ends of the two springs 205 are fixedly installed on the top inner wall of the two vertical grooves 304.

[0032] Specifically, the outer wall of the slide bar 301 is symmetrically provided with two inclined grooves 305, and two locking rods 306 are slidably installed in the two inclined grooves 305 respectively. The inner wall of each of the two inclined grooves 305 is provided with a sliding groove 307. The end of the locking rod 306 that is in contact with the inclined groove 305 is fixedly installed with a first slider 309, and the first slider 309 is slidably installed in the sliding groove 307.

[0033] Specifically, a second slider 310 is fixedly installed on both sides of the first slider 309, and a strip groove 308 is opened on both sides of the inner wall of the slide groove 307, and the second slider 310 is slidably installed in the strip groove 308.

[0034] Working principle: When using the device, if it is necessary to remove the hollow cylinder 201 and the sliding rod 301, first rotate the rotating rod 302 to rotate the two limiting blocks 303 to the positions corresponding to the L-shaped groove 203. Then, press the rotating rod 302 down to move the sliding rod 301 downward. Since the locking rod 306 is engaged in the sliding groove 307 through the first slider 309 and the second slider 310, when the sliding rod 301 slides downward, it will cause the two locking rods 306 to slide into the inclined groove 305. When the limiting block 303 slides down to the end of the L-shaped groove 203, the locking rod 306 will slide into the inclined groove 305. At this time, rotate the rotating rod 302 again to engage the limiting block 303 into the L-shaped groove 203. At the bottom, the rotating rod 302 and the sliding rod 301 will be limited. Then, slide the rotating rod 302 upward to remove the hollow cylinder 201 and the sliding rod 301. After changing the mold, reinsert the hollow cylinder 201 into the through hole 4, and then engage the two clamping plates 202 into the two clamping slots 5. At this time, rotate the rotating rod 302 to drive the limiting block 303 to disengage from the bottom of the L-shaped groove 203, thereby unlocking the rotating rod 302. When the rotating rod 302 is released, the two springs 205 will be released and push the rotating rod 302 to slide upward, which in turn drives the sliding rod 301 to slide upward. The upward sliding of the sliding rod 301 will push the two locking rods 306 to slide out, thereby fixing the hollow cylinder 201 and the sliding rod 301.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
