Description

Technical Field

[0001] The utility model belongs to the field of positioning, and in particular relates to a positioning device for a glass sealing connector. Background Art

[0002] Glass-sealed connectors offer excellent mechanical strength. This is because the glass-to-metal seal forms a hybrid chemical bond through the interweaving of the glass liquid and the metal oxide layer. This chemical bond is far stronger than the adhesion between plastic and metal. Therefore, glass-to-metal connectors offer sufficient tensile and torsional strength, as well as high-temperature resistance. Glass, an inorganic, non-metallic material, has a high softening point and does not release any harmful components when used in high-temperature environments. Plastic, on the other hand, is not only heat-resistant but also easily releases harmful components in such environments. This is why some connectors, particularly those requiring a complete seal at one end and serving as a working interface, cannot use plastic as the insulation material. Good sealing results in a very low leakage rate. Furthermore, like other insulating materials, glass exhibits excellent electrical performance parameters. Its insulation resistance and dielectric withstand voltage fully meet the connector's design requirements. It also offers strong corrosion resistance, making it suitable for harsh environments.

[0003] For example, announcement number CN218849962U discloses a glass-sealed connector positioning device, including a fixing plate, the fixing plate is fixedly connected with a connector, the end of the connector away from the fixing plate is buckled with an adapter, the connector and the adapter are externally buckled with a limiting device, the limiting device is provided with a rotating shaft, an inner core shaft is sleeved inside the rotating shaft, a first arc-shaped limiting plate is fixedly connected to both ends of the rotating shaft, a first cover plate is fixedly installed at the other end of the first arc-shaped limiting plate, a second arc-shaped limiting plate is fixedly connected to both ends of the inner core shaft, a second cover plate is fixedly installed at the other end of the second arc-shaped limiting plate, the first cover plate and the second cover plate are relatively penetrated by threaded holes, and the inner walls of the first arc-shaped limiting plate and the second arc-shaped limiting plate are provided with insulating glue.

[0004] In the above scheme, when the connector is connected to the adapter, the end of the first hole needle contacts the end of the second hole needle to realize the conductive function, and the connector and the adapter are connected through a limit device. However, in actual use, there is looseness between the connector or adapter and the limit device, or there is wear after long-term use, which may cause looseness between the connector and the adapter, or even if there is a small gap between the connector and the adapter, it will cause poor contact between the first hole needle and the second hole needle. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a glass sealing connector positioning device. Under the elastic force of the compression spring, the first hole needle always presses tightly against the second hole needle, so that there is no gap between the first hole needle and the second hole needle, thereby reducing poor contact.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A glass sealing connector positioning device, comprising:

[0008] a first sleeve, wherein the inner side of the first sleeve is slidably connected to the second sleeve, the inner wall of the second sleeve is fixedly connected to at least two sliding sleeves, a sliding rod is passed through the sliding sleeve, so that the sliding rod and the sliding sleeve are slidably connected, a compression spring is sleeved on the sliding rod, and both ends of the sliding rod are fixedly connected to a retaining ring, and the retaining ring is fixedly connected to the inner wall of the first sleeve, and the end of the first sleeve away from the compression spring is fixedly connected to a plurality of buckles, a first glass gel column is fixedly connected to the inner side of the second sleeve, and a plurality of first hole needles and at least two positioning columns are fixedly connected to the first glass gel column;

[0009] A third sleeve, wherein a plurality of clamping blocks are fixedly connected to the circumference of one end of the third sleeve, a clamping hole is provided on the clamping block, a second glass gel column is rotatably connected to the inner side of the third sleeve, a plurality of second pinholes and at least two positioning holes are provided on the second glass gel column, and a second needle is fixedly connected in the second pinhole.

[0010] The above technical solution, its principle and technical effects:

[0011] Align the positioning hole on the second glass gel column with the positioning post on the first glass gel column, and push the second glass gel column toward the first glass gel column so that the positioning post is inserted into the positioning hole and the first hole needle is aligned with the second needle hole. At this time, rotate the third sleeve so that the block and the buckle are offset. Continue to push the second glass gel column toward the first glass gel column until the first hole needle is inserted into the second needle hole and the first hole needle contacts the second hole needle. At this time, continue to push the second glass gel column toward the first glass gel column until the block contacts the retaining ring. During this process, since the first hole needle and the second hole needle have already contacted in advance, they will drive the first glass gel column, the sliding sleeve and the second sleeve to move along the sliding rod together, and the compression spring will be further compressed. Then rotate the third sleeve so that the buckle is aligned with the card hole. After releasing, the elastic force of the compression spring pushes the first glass gel column, the sliding sleeve and the second sleeve to move back a part along the sliding rod, so that the buckle is inserted into the card hole to achieve connection. Since the elastic force of the compression spring always exists and the second sleeve is not in contact with the retaining ring, the first hole needle always presses tightly against the second hole needle, so that there is no gap between the first hole needle and the second hole needle, thereby reducing poor contact.

[0012] In a preferred example, the present invention can be further configured as follows: the number of the first needles is the same as the number of the second needles, and the first needles are adapted to the second needle holes.

[0013] In a preferred example, the present invention can be further configured as follows: the number of the positioning posts is the same as the number of the positioning holes, and the positioning posts are adapted to the positioning holes.

[0014] In a preferred example, the present invention can be further configured as follows: the extended length of the positioning post is greater than the length of the first hole needle, and the end of the positioning post is a hemispherical structure.

[0015] In a preferred example, the present invention can be further configured as follows: the number of the buckles is the same as the number of the clamping blocks, and the buckles are adapted to the clamping holes.

[0016] In a preferred example, the present invention can be further configured as follows: it also includes a fixing plate, the fixing plate is fixedly connected to an end of the first sleeve away from the buckle, and a plurality of connection holes are opened on the peripheral side of the fixing plate.

[0017] In a preferred example, the present invention can be further configured as follows: the compression spring is sleeved between the retaining ring close to the fixing plate and the first glass gel column.

[0018] In a preferred example, the present invention can be further configured as follows: a rotating ring is fixedly connected to the middle of the inner side of the third sleeve, an annular groove is opened in the middle of the circumference of the second glass gel column, and the rotating ring is rotatably connected in the annular groove.

[0019] In a preferred example, the present invention can be further configured as follows: a threading cap is fixedly connected to an end of the third sleeve away from the clamping block.

[0020] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0021] A fixed connection is a connection in which parts or components are fixed without any relative movement. There are two types of connections: detachable and non-detachable.

[0022] (1) A removable connection is a method of fastening components together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0023] (2) Non-detachable connections mainly refer to welding, riveting, and tenoning. Since they require forging, sawing, or oxygen cutting to disassemble during repair or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to workmanship quality, technical inspection, and remedial measures (such as calibration, polishing, etc.).

[0024] A threaded connection refers to a detachable connection in which the connected parts are connected together using a threaded part (or the threaded part of the connected parts).

[0025] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0026] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0027] Beneficial effects of the utility model:

[0028] Under the elastic force of the compression spring, the first hole needle always presses tightly against the second hole needle, so that there is no gap between the first hole needle and the second hole needle, thereby reducing the situation of poor contact. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0040] According to the concept of this application, Figures 1 to 8 To describe an embodiment of a glass-sealed connector positioning device. Specifically, the glass-sealed connector positioning device is constructed as a split structure, which has components such as a first sleeve 1, a second sleeve 2, and a third sleeve 11. Through the mutual cooperation of the first glass gel column 8, the second glass gel column 14 and other structures, the positioning hole 16 on the second glass gel column 14 is aligned with the positioning column 10 on the first glass gel column 8, and the second glass gel column 14 is pushed toward the first glass gel column 8, so that the positioning column 10 is inserted into the positioning hole 16, so that the first hole needle 9 is aligned with the second needle hole 15. At this time, the third sleeve 11 is rotated so that the block 12 is staggered with the buckle 7. Continue to push the second glass gel column 14 toward the first glass gel column 8 until the first hole needle 9 is inserted into the second needle hole 15 and the first hole needle 9 contacts the second hole needle 17. At this time, continue to push the second glass gel column 14 toward the first glass gel column 8 until the block 12 contacts the retaining ring 6. During this process, since the first hole needle 9 and the second hole needle 17 have already contacted in advance, they will drive the first glass gel column 8, the sliding sleeve 3 and the second sleeve 2 to move along the slide rod 4, and the compression spring 5 will be further compressed. Then rotate the third sleeve 11 so that the buckle 7 is aligned with the clamping hole 13. After releasing the hand, the elastic force of the compression spring 5 pushes the first glass gel column 8, the sliding sleeve 3 and the second sleeve 2 to move back along the slide rod 4 partly, so that the buckle 7 is inserted into the clamping hole 13 to achieve connection. Since the elastic force of the compression spring 5 is always present and the second sleeve 2 is not in contact with the retaining ring 6, the first hole needle 9 is always tightly against the second hole needle 17, so that there is no gap between the first hole needle 9 and the second hole needle 17, reducing the possibility of poor contact.

[0041] like Figure 1-8 As shown, a glass sealing connector positioning device includes:

[0042] A first sleeve 1, the inner side of the first sleeve 1 is slidably connected to the second sleeve 2, the inner wall of the second sleeve 2 is fixedly connected to at least two sliding sleeves 3, a sliding rod 4 is passed through the sliding sleeve 3, so that the sliding rod 4 and the sliding sleeve 3 are slidably connected, a compression spring 5 is sleeved on the sliding rod 4, and both ends of the sliding rod 4 are fixedly connected to a retaining ring 6, the retaining ring 6 is fixedly connected to the inner wall of the first sleeve 1, and the end of the first sleeve 1 away from the compression spring 5 is fixedly connected to a plurality of buckles 7, the inner side of the second sleeve 2 is fixedly connected to a first glass gel column 8, and the first glass gel column 8 is fixedly connected to a plurality of first hole needles 9 and at least two positioning columns 10;

[0043] The third sleeve 11 has a plurality of clamping blocks 12 fixedly connected to the circumference of one end of the third sleeve 11, and a clamping hole 13 is provided on the clamping block 12. A second glass gel column 14 is rotatably connected to the inner side of the third sleeve 11, and a plurality of second pinholes 15 and at least two positioning holes 16 are provided on the second glass gel column 14. A second needle 17 is fixedly connected in the second pinhole 15.

[0044] During use, align the positioning hole 16 on the second glass gel column 14 with the positioning column 10 on the first glass gel column 8, and push the second glass gel column 14 toward the first glass gel column 8 so that the positioning column 10 is inserted into the positioning hole 16 and the first hole needle 9 is aligned with the second needle hole 15. At this time, rotate the third sleeve 11 so that the clamping block 12 and the buckle 7 are offset. Continue to push the second glass gel column 14 toward the first glass gel column 8 until the first hole needle 9 is inserted into the second needle hole 15 and the first hole needle 9 contacts the second hole needle 17. At this time, continue to push the second glass gel column 14 toward the first glass gel column 8 until the clamping block 12 contacts the retaining ring 6. During this process, since the first hole needle 9 and the second hole needle 17 have already contacted in advance, they will drive the first glass gel column 8, the sliding sleeve 3 and the second sleeve 2 to move along the sliding rod 4, and the compression spring 5 will be further compressed. Then, the third sleeve 11 is rotated so that the buckle 7 is aligned with the locking hole 13. After releasing the grip, the elastic force of the compression spring 5 pushes the first glass gel column 8, the sliding sleeve 3, and the second sleeve 2 back along the slide rod 4, so that the buckle 7 is inserted into the locking hole 13, completing the connection. Because the elastic force of the compression spring 5 is always present and the second sleeve 2 is not in contact with the retaining ring 6, the first pin 9 is always tightly pressed against the second pin 17, eliminating any gap between the first pin 9 and the second pin 17, thereby minimizing the possibility of poor contact.

[0045] In one embodiment of the present invention, the number of first pins 9 is the same as the number of second pins 17, and the first pins 9 are adapted to the second pinholes 15. The first pins 9 and the second pinholes 15 can be aligned, and the first pins 9 can be fully inserted into the second pinholes 15, so that the first pins 9 can contact the second pins 17 to achieve the conductive function.

[0046] In one embodiment of the present invention, the number of positioning posts 10 is the same as the number of positioning holes 16, and the positioning posts 10 are adapted to the positioning holes 16. The positioning posts 10 and the positioning holes 16 can be aligned, so that the first needle 9 and the second needle hole 15 can be aligned to achieve the positioning effect.

[0047] In one embodiment of the present invention, the extended length of the positioning post 10 is greater than the length of the first pin 9, and the end of the positioning post 10 is hemispherical. The hemispherical structure facilitates the insertion of the positioning post 10 into the positioning hole 16. When the positioning post 10 is inserted into the positioning hole 16 first, the first pin 9 and the second pinhole 15 can be aligned, thereby preventing the positioning post 10 from being unable to achieve the positioning function of the positioning hole 16 due to the first pin 9 being too long.

[0048] In one embodiment of the present invention, the number of the buckles 7 is the same as the number of the clamping blocks 12, and the buckles 7 are adapted to the clamping holes 13. This allows the buckles 7 to be fully inserted into the clamping holes 13 to achieve the connection.

[0049] One embodiment of the present invention further includes a fixing plate 18, which is fixedly connected to the end of the first sleeve 1 away from the buckle 7. The fixing plate 18 has a plurality of connection holes 19 formed around the side thereof. This facilitates the fixing plate 18 to fix the first sleeve 1, thereby securing the first sleeve 1. The wire passes through the fixing plate 18 and is connected to the first pin 9.

[0050] In one embodiment of the present invention, the compression spring 5 is sleeved between the retaining ring 6 near the fixing plate 18 and the first glass gel column 8. This design allows the compression spring 5 to squeeze the first glass gel column 8, forcing the first glass gel column 8 toward the second glass gel column 14, eliminating a gap between the first and second aperture needles 9, 17 and reducing contact problems.

[0051] In one embodiment of the present invention, a rotating ring 20 is fixedly connected to the center of the inner side of the third sleeve 11. An annular groove 21 is defined in the center of the circumference of the second glass gel column 14. The rotating ring 20 is rotatably connected to the annular groove 21. This design allows the third sleeve 11 and the second glass gel column 14 to rotate relative to each other.

[0052] In one embodiment of the present invention, a wire cap 22 is fixedly connected to one end of the third sleeve 11 away from the clamping block 12 , making it convenient for the worker to connect the wire to the second pinhole 15 .
