Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum conductive equipment technology, and in particular to a vacuum magnetic conductive device. Background Technology
[0002] During the research and development and testing of liquid products, it is often necessary to operate them in a vacuum environment to test their electrical conductivity, thermal conductivity and other properties under vacuum conditions.
[0003] When different devices are tested in a vacuum environment, they are generally connected to electrodes inside the vacuum chamber using aviation connectors. Because aviation connectors need to ensure the stability of the male and female plugs, the male and female plugs of the aviation connectors are often very tightly connected. When inserting and removing them, operators not only need to use a lot of force, but also need to strictly align the male and female plugs of the aviation connector to make them fit together, which is very inconvenient. To address this, we propose a magnetic conductive device for use in a vacuum environment. Utility Model Content
[0004] The purpose of this invention is to solve the problem of difficulty in plugging and unplugging aviation sockets used to connect high vacuum electrodes and equipment when different devices are tested in a vacuum chamber, and to propose a vacuum magnetic conductive device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A vacuum magnetic attraction conductive device includes a magnetic male connector connected to a high vacuum electrode and a magnetic female connector mating with the magnetic male connector. The magnetic male connector includes two first conductive rods connected to the high vacuum electrode, and the magnetic female connector includes two second conductive rods connected to external devices. The first conductive rods and the second conductive rods are inserted into each other.
[0007] A first magnet is provided on one side of the first conductive rod, and a second magnet that is attracted to the first magnet is provided on one side of the second conductive rod.
[0008] Furthermore, the magnetic male connector also includes a first mounting base, with first conductive rods at both ends and a first magnet in the middle of the first mounting base;
[0009] The magnetic female head also includes a second mounting base, with second conductive rods at both ends and a second magnet in the middle.
[0010] Furthermore, a slot is provided along the axis at one end of the first conductive rod near the second conductive rod;
[0011] The second conductive rod has a plug corresponding to the slot at one end near the first conductive rod along the axis, and the second conductive rod and the first conductive rod are connected together by the plug and the slot.
[0012] Furthermore, a first threaded portion is provided on the circumferential surface of the first mounting base near the slot. The first threaded portion is movably inserted into the first mounting base, and two adjusting nuts are engaged on the first threaded portion. The two adjusting nuts are located on both sides of the first mounting base.
[0013] Furthermore, a second threaded portion is provided on the circumferential surface of the second mounting base near the plug end. The second threaded portion is movably inserted into the second mounting base. Two adjusting nuts are engaged on the second conductive rod, and the two adjusting nuts are located on both sides of the second mounting base.
[0014] Furthermore, the end of the second conductive rod away from the magnetic male head is provided with a terminal block for connecting to an external device.
[0015] Furthermore, the terminal block includes a terminal block, a pole bolt, and a wiring bolt. The terminal block is connected to the second mounting base via the pole bolt, and the terminal block is connected to the wires of the external equipment via the wiring bolt.
[0016] Compared with the prior art, this utility model provides a vacuum magnetic attraction conductive device, which has the following beneficial effects:
[0017] This utility model relates to a vacuum magnetic conductive device. In use, the end of the magnetic male connector furthest from the magnetic female connector is connected to the two electrodes of the high-vacuum electrode within the vacuum chamber. The end of the magnetic female connector furthest from the magnetic male connector is connected to a resistance wire or metal electrode. Then, the first and second conductive rods are plugged in and energized. Simultaneously, the first and second magnets attract each other magnetically, stably connecting the first and second conductive rods. Compared to traditional aviation sockets, this device only requires slight alignment of the first and second conductive rods during insertion and removal. The magnetic force within the supports of the first and second magnets automatically connects the first and second conductive rods. No special force is required when removing them, significantly improving ease of operation. Furthermore, the device has a simple structure, low maintenance costs, low overall cost, and is less prone to malfunctions.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Reference Figure 1-5 The present invention relates to a vacuum magnetic attraction conductive device, comprising a magnetic male head 2 connected to a high vacuum electrode 1 and a magnetic female head 3 mating with the magnetic male head 2. The magnetic male head 2 includes two first conductive rods 202 connected to the high vacuum electrode 1. The two first conductive rods 202 are divided into a positive conductive rod and a negative conductive rod, which are respectively connected to the positive terminal and the negative terminal on the high vacuum electrode 1.
[0028] The magnetic female connector 3 includes two second conductive rods 302 that connect to external devices. The two second conductive rods 302 are also divided into positive conductive rods and negative conductive rods, which correspond to the first conductive rod 202 and are connected to the positive and negative terminals of the wires of the external devices.
[0029] The first conductive rod 202 and the second conductive rod 302 are detachably connected together.
[0030] A first magnet 204 is installed on one side of the first conductive rod 202, and a second magnet 304 that attracts the first magnet 204 is installed on one side of the second conductive rod 302. Both the first magnet 204 and the second magnet 304 are neodymium iron boron high-temperature resistant strong magnets. During installation, they are set according to the mutual attraction between the first magnet 204 and the second magnet 304.
[0031] When the first conductive rod 202 and the second conductive rod 302 are detachably connected, the first magnet 204 and the second magnet 304 attract each other, so that the first conductive rod 202 and the second conductive rod 302 are stably connected together and will not separate freely.
[0032] The magnetic male connector 2 also includes a first mounting base 201, with first conductive rods 202 mounted at both ends of the first mounting base 201 and a first magnet 204 mounted in the middle of the first mounting base 201.
[0033] The magnetic female head 3 also includes a second mounting base 301. The two ends of the second mounting base 301 are equipped with second conductive rods 302 corresponding to the first conductive rods 202, and the middle of the second mounting base 301 is equipped with a second magnet 304 corresponding to the first magnet 204. Both the first mounting base 201 and the second mounting base 301 are insulators.
[0034] When the first conductive rod 202 is aligned with the second conductive rod 302, the first magnet 204 is also aligned with the second magnet 304. When the first conductive rod 202 and the second conductive rod 302 are inserted together, the magnetic force of the first magnet 204 and the second magnet 304 begins to act, keeping the first conductive rod 202 and the second conductive rod 302 inserted.
[0035] A slot 205 is machined along the axis at one end of the first conductive rod 202 near the second conductive rod 302, and a plug 305 corresponding to the slot 205 is integrally formed along the axis at one end of the second conductive rod 302 near the first conductive rod 202. The second conductive rod 302 and the first conductive rod 202 are connected together by the plug 305 and the slot 205.
[0036] The first conductive rod 202 and the second conductive rod 302 are connected together by a plug 305 and a slot 205. This connection increases the contact area between the first conductive rod 202 and the second conductive rod 302, facilitating conductivity. It also gives the connection structure between the first conductive rod 202 and the second conductive rod 302 radial bearing capacity (taking the radial direction of the first conductive rod 202 as an example), further increasing the stability of the connection between the first conductive rod 202 and the second conductive rod 302.
[0037] A first threaded portion 203 is machined on the circumferential surface of the first mounting base 201 near the slot 205. The first threaded portion 203 is movably inserted into the first mounting base 201. Two adjusting nuts 307 are engaged on the first threaded portion 203. The two adjusting nuts 307 are located on both sides of the first mounting base 201. By adjusting the position of the two adjusting nuts 307 on the first threaded portion 203, the relative position between the first conductive rod 202 and the first mounting base 201 can be adjusted. After adjusting to the corresponding position, the two adjusting nuts 307 are used to clamp and fix the relative position between the first conductive rod 202 and the first mounting base 201. In this way, the distance between the first magnet 204 and the second magnet 304 can be adjusted, thereby changing the magnetic force between the first magnet 204 and the second magnet 304. According to the weight of the external device's wires and the operator's usage habits, the magnetic force can be adjusted to a suitable value, further improving the convenience of operation.
[0038] A second threaded portion 303 is provided on the circumferential surface of the second mounting base 301 near the plug 305. The second threaded portion 303 is movably inserted into the second mounting base 301. Two adjusting nuts 307 are engaged on the second conductive rod 302. The two adjusting nuts 307 are located on both sides of the second mounting base 301. By cooperating with the second threaded portion 303, the relative position between the second conductive rod 302 and the second mounting base 301 can be adjusted. In conjunction with the first magnet 204 on the magnetic male head 2, the distance between the first magnet 204 and the second magnet 304 can be adjusted, making the adjustment more flexible.
[0039] The end of the second conductive rod 302 away from the magnetic male connector 2 is connected to a terminal 4 for wiring with external equipment. The magnetic female connector 3 is connected to the resistance wire or metal electrode (selected according to the test item) through the terminal 4. The terminal 4 and the magnetic female connector 3 are connected through the second conductive rod 302.
[0040] The terminal block 4 includes a terminal block 401, a pole bolt 402, and a wiring bolt 403. The terminal block 401 has a pole hole and a wiring hole. The terminal block 401 is connected to the second mounting base 301 by the pole bolt 402. The pole bolt 402 passes through the pole hole and is then screwed together with the second conductive rod 302, thus connecting the terminal block 401 and the second conductive rod 302 together.
[0041] The terminal block 401 is connected to the external device (resistance wire or metal electrode) via a terminal bolt 403. The terminal bolt 403 is screwed into the terminal hole, pressing the wire of the resistance wire or metal electrode into the terminal hole, thereby connecting to the external device.
[0042] Working principle: When using, first loosen the adjusting nut 307, adjust the position of the first magnet 204 and the second magnet 304, and control the distance between the first magnet 204 and the second magnet 304 so that the magnetic force between them can maintain the connection stability between the magnetic male head 2 and the magnetic female head 3.
[0043] Then, thread the magnetic male connector 2 to the high vacuum electrode 1 inside the vacuum chamber and lock it in place. Connect the magnetic female connector 3 to the power cord of the external device. Align the plug 305 with the slot 205 and insert it in place. Under the magnetic attraction of the first magnet 204 and the second magnet 304, the plug will remain stable and will not come off.
