Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, and in particular to a positioning fixture for heat shrinking wire terminal sleeves. Background Technology

[0002] Wire terminals, also known as wiring terminals, are accessories used to achieve electrical connections. Their main function is to transmit electrical signals or conduct electricity. They are commonly used in various electrical equipment and systems. When installing wire terminals, heat shrink tubing is usually required to improve the insulation and waterproofing of the wire and ensure the safety of the wire.

[0003] Chinese patent CN220031184U discloses a positioning fixture for heat-shrinking wire terminal sleeves. The key technical features include: a reference fixture plate; a movable fixture plate; a movable component mounted on the reference fixture plate and connected to it; a pressure plate; and a pressing component mounted on top of the movable fixture plate and connected to it. The reference fixture plate has a rectangular through-hole at its top and multiple terminal positioning slots evenly spaced in a straight line. Each terminal positioning slot is located on one side of the rectangular through-hole, and a positioning post is fixed inside the bottom of each terminal positioning slot. This invention straightens the wires, preventing them from overlapping, and also straightens the heat-shrinkable wire sleeve, improving the heating effect.

[0004] Existing technologies often have the following drawbacks: When using a positioning fixture to attach heat shrink tubing to wire terminals, multiple wires need to be inserted at once. This makes it difficult to ensure that the wire lengths between the moving fixture plate and the reference fixture plate are the same when using a pressure plate to fix the wires. Consequently, when straightening the wires by adjusting the screw and moving fixture plate, it is impossible to ensure that multiple wires are straightened at the same time.

[0005] Therefore, this utility model provides a positioning fixture for heat shrinking wire terminal sleeves. Utility Model Content

[0006] The purpose of this utility model is to solve the problem in the existing technology where, when using a positioning fixture for heating heat shrink tubing with wire terminal sleeves, multiple wires need to be inserted at once.

Consequently, when straightening the wires by adjusting the screw and moving fixture plate, it is impossible to ensure that multiple wires are straightened at the same time.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a positioning fixture for heat shrinking wire terminal sleeves, including a reference fixture plate 1, a movable fixture plate 2 installed on the side of the reference fixture plate 1, an adjusting screw 4 threaded into the inner wall of the movable fixture plate 2, the adjusting screw 4 being rotatably connected to the reference fixture plate 1, a pressure plate 3 installed on the upper surface of the movable fixture plate 2, a plurality of spring plates 5 installed on the side of the pressure plate 3 near the movable fixture plate 2, a moving device 6 provided on the surface of the movable fixture plate 2, and limiting devices 7 provided on both sides of the movable fixture plate 2.

[0031] The following section will describe in detail the specific settings and functions of its moving device 6 and limiting device 7.

[0032] Reference Figures 1-4As shown in this embodiment: the moving device 6 includes several connecting plates 607, all of which are installed on the side of the pressure plate 3 near the moving jig plate 2. All connecting plates 607 are fixedly connected to the spring plate 5. The moving jig plate 2 has several sliding grooves inside, and each of the sliding grooves on the moving jig plate 2 has a sliding strip 601 slidably connected to it. A moving plate 602 is fixedly connected to the side of the sliding strip 601 near the pressure plate 3. A pad 603, made of rubber, is glued to the side of the moving plate 602 away from the sliding strip 601. By setting the connecting plates 607 and the sliding strips 601, the spring plate and the moving plate 602 can be moved, thereby adjusting the different straightening requirements of multiple wires. The pad 603 improves the wire fixing effect. Several fixing plates 604 are fixedly connected to the side of the movable jig plate 2 closest to the reference jig plate 1. Each fixing plate 604 is fixedly connected to a fixing rod 605 on the side closest to the slide bar 601. The fixing rods 605 are slidably connected to the inner wall of the slide bar 601. By setting the fixing plates 604, the fixing rods 605 can be connected to the movable jig plate 2. The fixing rods 605 slidably connected to the inner wall of the slide bar 601 can avoid affecting the movement of the slide bar 601.

[0033] A first spring 606 is fitted onto the surface of the fixing rod 605, and both ends of the first spring 606 are fixedly connected to the fixing plate 604 and the slide bar 601, respectively. By setting the fixing rod 605, the position of the first spring 606 can be restricted, and the position of the slide bar 601 can also be restricted. Several slide rods 609 are slidably connected to the inner wall of the pressure plate 3, and each slide rod 609 is fixedly connected to a push plate 608 at one end near the reference fixture plate 1. The push plate 608 is fixedly connected to the connecting plate 607. The slide rods 609 slidably connected to the inner wall of the pressure plate 3 can move. By setting the slide rods 609 and the push plate 608, a stable connection between the connecting plate 607 and the pressure plate 3 is ensured, while also allowing the connecting plate 607 to move. A mounting plate 610 is fixedly connected to one end of each sliding rod 609 away from the push plate 608. A second spring 611 is fitted onto the surface of each sliding rod 609, and the two ends of the second spring 611 are fixedly connected to the pressure plate 3 and the mounting plate 610, respectively. By setting the mounting plate 610, the second spring 611 can be installed, and by setting the second spring 611, a stable connection between the sliding rod 609 and the pressure plate 3 is ensured.

[0034] Reference Figure 1 and Figure 2 as well as Figure 5As shown, specifically, the limiting device 7 includes two "L"-shaped plates 71, which are fixedly connected to both sides of the movable jig plate 2. Connecting rods 72 are slidably connected to the inner walls of both "L"-shaped plates 71. An arc-shaped block 73 is fixedly connected to the end of each connecting rod 72 near the pressure plate 3, and the side of the arc-shaped block 73 near the pressure plate 3 is arc-shaped. By setting the "L"-shaped plates 71, the connecting rods 72 and the arc-shaped blocks 73 can be connected to the movable jig plate 2. The connecting rods 72, slidably connected to the inner walls of the "L"-shaped plates 71, can move. By setting the arc-shaped blocks 73, the position of the pressure plate 3 can be limited.

[0035] Stabilizing plates 74 are fixedly connected to the sides of the two L-shaped plates 71 that are close to each other. The stabilizing plates 74 are tightly fitted to the connecting rod 72. A pull plate 75 is fixedly connected to the end of the connecting rod 72 away from the arc-shaped block 73. A third spring 76 is sleeved on the surface of the connecting rod 72, and the two ends of the third spring 76 are fixedly connected to the pull plate 75 and the L-shaped plates 71, respectively. By setting the pull plate 75, the movement of the connecting rod 72 and the installation of the third spring 76 can be facilitated. By setting the third spring 76, the position of the connecting rod 72 can be restricted. By setting the stabilizing plates 74, the stability of the connecting rod 72 during movement can be improved.

[0036] Working principle: When using a positioning fixture to attach heat-shrink tubing to wire terminals via a wire terminal sleeve, the wire is first installed inside the reference fixture plate 1 and the movable fixture plate 2. The wire is then fixed by the pressure plate 3 and the spring plate 5. Next, the adjusting screw 4 is rotated to move the movable fixture plate 2 away from the reference fixture plate 1, straightening the wire. During the straightening process, when some wire has been straightened but some still needs further straightening, the already straightened wire, through friction, moves the pad 603, the movable plate 602, the spring plate 5, and the connecting plate 607. This causes the slider 601 to slide on the surface of the fixed rod 605, and the connecting plate 607, through the push plate 608, drives the slider 609 to slide on the inner wall of the pressure plate 3. 601 moves the movable plate 602 closer to the fixed plate 604 and the mounting plate 610 closer to the pressure plate 3, thereby adjusting the straightening requirements of different wires. After the heat shrink tubing is installed, the movable pressure plate 3 moves away from the movable fixture plate 2. At this time, under the action of the first spring 606 and the second spring 611, the slider 601 and the mounting plate 610 move away from the fixed plate 604 and the pressure plate 3 respectively, and then the wire can be removed. By setting the movable device 6, after the wire is installed in the movable fixture plate 2, the wire can be straightened according to the different bending conditions of multiple wires during the straightening process of the wire by the movable fixture plate 2, thereby ensuring the effect of straightening multiple wires at one time using the positioning fixture for heating heat shrink tubing with wire terminal sleeves as much as possible.

[0037] When it is necessary to install the wire into the movable jig plate 2, pull the pressure plate 3 to move it away from the movable jig plate 2. During the movement of the pressure plate 3, it pushes the arc-shaped block 73 to move, causing the connecting rod 72 to slide on the inner wall of the "L"-shaped plate 71. After the pressure plate 3 moves away from the arc-shaped block 73, under the action of the elastic force of the third spring 76, the pull plate 75 moves closer to the pressure plate 3, releasing the pressure plate 3. At this time, the arc-shaped block 73 can restrict the position of the pressure plate 3. Then, the wire is installed into the movable jig plate 2, completing the wire installation. Then, pulling the pull plate 75 moves the connecting rod 72, causing the arc block 73 to move closer to the stabilizing plate 74. At this time, the arc block 73 releases the restriction on the position of the pressure plate 3, and the pressure plate 3 moves the spring plate 5 closer to the wire, completing the installation of the wire. By setting the limiting device 7, the position of the pressure plate 3 can be restricted after the moving pressure plate 3 moves away from the moving jig plate 2, avoiding the situation where the staff needs to continuously pull the pressure plate 3 during the installation of the wire, thus facilitating the installation of multiple wires into the interior of the moving jig plate 2.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
