Description

Technical Field

[0001] The invention relates to the technical field of radar transceiver assembly welding, and in particular to a multi-channel TR assembly welding tool. Background Art

[0002] As the core component of phased array radar, the development of multi-channel TR components (Transmit / Receive) shows a trend of technological progress, market expansion and application expansion. The characteristics of multi-channel TR components are mainly reflected in structural design and functional realization, which undoubtedly poses higher challenges to shell design, cover sealing welding, connector welding, circuit board design, and high heat consumption devices.

[0003] The airtightness requirements of multi-channel TR components are very important and directly related to the performance and reliability of the components.

[0004] Therefore, the connectors of the components are often welded. Welding the connector to the tube shell can achieve the following points:

[0005] Electrical connection: A good electrical connection is formed between the connector and the tube shell to ensure the smooth flow of current, thereby realizing the intended function of the circuit;

[0006] Mechanical fixation: Welding not only ensures the physical fixation of the connector, but also protects the stability and reliability of the connector in various environments through its mechanical strength and corrosion resistance;

[0007] Environmental protection: The welded connector can better resist the influence of the external environment, such as waterproof, dustproof and corrosion-resistant, ensuring the normal use of the connector in harsh environments;

[0008] Electromagnetic shielding: For connectors with shielding function, the welded shell adopts a full metal electric shielding structure design, which can effectively shield external electromagnetic interference and protect the stable operation of the circuit inside the electrical connector.

[0009] The quality of welded connectors directly affects the performance of the components. Currently, the widely used welding tools are designed for connectors that are embedded or flush with the shell surface, which can ensure that the connector meets the user's required engagement depth after welding.

[0010] As component structure design becomes more and more complex, many designs of connectors protruding from the shell appear. When the connector protrudes from the shell surface, it is difficult to ensure that the multi-channel connectors are parallel and perpendicular to the shell surface after welding the connector to the shell with the original welding tool. The longer the connector is exposed from the shell surface, the more serious the tilt. When connecting with the matching product, it is difficult to plug in, and even the connector pins may be knocked crooked or broken.

[0011] Based on this, it is necessary to develop and design a multi-channel TR component welding tooling. Summary of the invention

[0075] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, and methods are omitted so as not to obscure the description of the present invention with unnecessary details.

[0076] In order to make the purpose, technical solutions and advantages of the present invention more clear, a specific implementation method will be described below in conjunction with the accompanying drawings.

[0077] The following is a detailed description of an embodiment of the present invention. This example is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0078] like Figure 1-10 As shown, the embodiment of the present invention provides a multi-channel TR assembly welding tool, which is described in detail as follows:

[0079] A multi-channel TR component welding tool, comprising:

[0080] The chassis 210, the ejector assembly 310, the slide bar and the first fixing column 320;

[0081] The upper surface of the chassis 210 is provided with a positioning groove 211, and the periphery of the positioning groove 211 is provided with positioning holes;

[0082] The fixed end of the slide bar is fixedly connected to the upper surface of the chassis 210, and the axis of the slide bar is parallel to and higher than the upper surface of the chassis 210;

[0083] The side of the ejector assembly 310 is provided with a sliding hole, and the upper surface of the ejector assembly 310 is provided with a penetrating fixing hole;

[0084] When the ejector assembly 310 slides along the slide rod through the slide hole and passes through the first fixing column 320 to penetrate the fixing hole and the positioning hole, the ejector assembly 310 is fixed to one side of the positioning groove 211;

[0085] When the multi-channel TR assembly is inserted into the positioning groove 211 and the ejector assembly 310 is fixed to one side of the positioning groove 211 , the front end extension of the ejector assembly 310 abuts against the connector on the side of the multi-channel TR assembly.

[0086] For example, Figure 1 As shown, the multi-channel TR component is provided with a plurality of multi-channel TR component welding positions 102 on its side, and these multi-channel TR component welding positions 102 are usually holes. The connector is placed in the hole and welded to the multi-channel TR component body 101. The structural design of the connector protruding from the shell surface causes the connectors to be non-parallel to each other and non-perpendicular to the shell surface after welding, and to tilt to varying degrees. During assembly, it is found that the plug-in is difficult, and even the connector pins are knocked crooked or broken, and the product is often repaired, which increases a lot of time and economic costs.

[0087] Based on this, the present invention provides a welding tool with a simple structure and convenient operation. The tool is composed of a chassis 210, a pin assembly 310, a slide rod and a first fixed column 320 structural parts, with low processing cost and simple assembly. It can be reused for multiple times for multi-channel TR components produced in batches, and at the same time ensures that the connector after welding meets the user's required engagement depth and the connectors are parallel to each other and perpendicular to the shell surface, solving the problem of difficulty in plugging with user products and increasing the probability of product success at one time.

[0088] The chassis 210 of the present invention is provided with a rectangular groove, which is adapted to the shape of the multi-channel TR assembly, and has arc-shaped expansion grooves at the four corners of the rectangular groove. The slide bar is parallel to and higher than the upper surface of the chassis 210, and is parallel to the upper surface.

[0089] A sliding hole is provided on the side of the ejector assembly 310 , and the ejector assembly 310 slides toward the positioning groove 211 through the sliding of the sliding hole and the sliding rod.

[0090] The upper surface of the ejector assembly 310 is provided with a fixing hole, and the chassis 210 is provided with a positioning hole at a corresponding position. When the fixing hole and the positioning hole coincide with each other, the first fixing column 320 is inserted to complete the positioning of the ejector assembly 310 .

[0091] The ejector assembly 310 is provided with a plurality of ejector pins, the front ends of which have an elastic and retractable structure. When the ejector assembly 310 is positioned by the first fixing column 320 and the sliding rod, the front ends of the ejector pins press against the connector to accurately position the connector on the multi-channel TR assembly. In this state, the connector can be placed in a welding furnace to complete welding.

[0092] The welding tool of the present invention can solve the problem that after the connector is welded, the component product meets the use requirements, has the characteristics of low processing cost, simple structure, easy processing, convenient assembly, and can be reused many times.

[0093] In some embodiments, the sliding rod includes: a second fixing column 410 and a sliding rod body 420;

[0094] The second fixing column 410 is fixedly disposed on the upper surface of the chassis 210;

[0095] One end of the sliding rod body 420 is fixedly connected to the side surface of the second fixing column 410;

[0096] The axis of the sliding rod body 420 is parallel to and higher than the upper surface of the chassis 210 .

[0097] In some embodiments, the sliding rod body 420 is threadedly connected to the second fixing column 410 .

[0098] For example, Figure 2 , Figure 3 As shown, in an application scenario, the second fixing column 410 of the sliding rod is fixed to the chassis 210 by screws, and a thread of a section of the sliding rod body is screwed into the threaded hole on the side of the second fixing column 410, so that the sliding rod body is parallel to and higher than the upper surface of the chassis 210.

[0099] In some embodiments, the ejector assembly 310 includes: a first fixing plate 510, a second fixing plate 520, and a spring ejector 530;

[0100] The main body of the spring ejector pin 530 is a column with a boss at the front end;

[0101] The first fixing plate 510 is provided with fixing holes penetrating the upper and lower surfaces, first mounting holes penetrating the two sides, and sliding holes penetrating the two sides;

[0102] The second fixing plate 520 is provided with second mounting holes penetrating through two sides;

[0103] The column part of the spring ejector 530 body passes through the first mounting hole and abuts against the side of the first fixing plate 510 through the boss, the telescopic part of the spring ejector 530 passes through the second mounting hole and extends out of the side of the second fixing plate 520, and the side of the second fixing plate 520 is fixedly connected to the side of the first fixing plate 510 to fix the spring ejector 530 body;

[0104] The sliding hole is slidably connected to the sliding rod, and the first fixing column 320 passes through the fixing hole.

[0105] In some embodiments, the multi-channel TR assembly welding tooling includes a top column 540;

[0106] The front end of the telescopic portion of the spring ejector pin 530 is provided with a threaded hole;

[0107] One end of the top column 540 is provided with a connection hole or an external thread;

[0108] The spring ejector pin 530 is connected to the ejector post 540 by inserting the telescopic portion into the connecting hole of the ejector post 540 , or the spring ejector pin 530 is connected to the ejector post 540 by screwing the ejector post 540 into the threaded hole.

[0109] For example, Figure 3 As shown, the ejector pin assembly 310 is a plurality of spring ejector pins 530 fixed by two fixing plates.

[0110] Specifically, one of the fixing plates is provided with a sliding hole and a fixing hole. As mentioned above, the sliding hole is slidably connected to the sliding rod, so as to approach the positioning groove 211 of the chassis 210 from the side. When the fixing hole is aligned with the positioning hole, the first fixing column 320 is inserted to complete the positioning of the ejector assembly 310.

[0111] The two fixing plates are respectively provided with a plurality of mounting holes for mounting the spring ejector pin 530, wherein the mounting holes of the fixing plate located on the outside are used to accommodate the body of the spring ejector pin 530, and the mounting holes of the fixing plate located on the inside are used to press the body of the spring ejector pin 530 and extend the telescopic end of the spring ejector pin 530. The front end of the spring ejector pin body is generally provided with a boss to prevent it from slipping off the fixing plate.

[0112] In fact, in some scenarios, a push post 540 is provided at the front end of the spring ejector 530. The telescopic end of the spring ejector 530 is provided with a threaded hole, and the push post 540 is either provided with a hole, and the push post 540 is inserted into the telescopic end of the spring ejector 530 through the hole; or the push post 540 is provided with an external thread, and the push post 540 is screwed into the threaded hole of the telescopic end of the spring ejector 530 through the external thread to be fixed to the telescopic end of the spring ejector 530 as a whole.

[0113] The top post 540 provided at the front end of the spring ejector pin 530 can be adapted to the structure of the mounting hole of the multi-channel TR component for mounting the connector. The present invention provides three typical ejector posts 540, which are discussed from the following aspects.

[0114] In some embodiments, the top column 540 is made of polytetrafluoroethylene;

[0115] The top column 540 is a long cube, and two connection holes are provided on the side of the top column 540;

[0116] The telescopic parts of the two spring ejector pins 530 are respectively inserted into the two connecting holes of the ejector post 540 to be connected with the ejector post 540 .

[0117] In some embodiments, the top column 540 is made of polytetrafluoroethylene;

[0118] The top column 540 is a column, the diameter of the first section and the diameter of the third section of the top column 540 are both smaller than the diameter of the second section, and the third section of the top column 540 is provided with an external thread;

[0119] The ejector column 540 is screwed into the threaded hole of the telescopic portion of the spring ejector pin 530 through the external thread of the third section to be connected to the spring ejector pin 530 .

[0120] In some embodiments, the top column 540 is made of polytetrafluoroethylene;

[0121] The top column 540 is a column, the diameter of the first section of the column is larger than the diameter of the second section, and the second section of the top column 540 is provided with an external thread;

[0122] The ejector column 540 is screwed into the threaded hole of the telescopic portion of the spring ejector pin 530 through the external thread of the second section to be connected to the spring ejector pin 530 .

[0123] For example, Figure 6 As shown in the figure, a push column 540 is divided into three sections, wherein the left section is an external thread section and the right section is an insertion section. The push column 540 is threadedly connected to the threaded hole at the front end of the spring push pin 530 through the external thread on the left side. The right side is used to tighten the connector.

[0124] This type of top post 540 is suitable for the case where the connector is in the hole of the multi-channel TR component, or the case where the connector connection end is a hole. The right section of the top post 540 is used for insertion, and after insertion, the diameter of the right section of the top post 540 and the hole of the multi-channel TR component have a small gap; or after the right section of the top post 540 is inserted, the diameter of the right section of the top post 540 and the hole of the connector connection end have a small gap; in other words, the right diameter of the top post 540 is adapted to the installation hole of the multi-channel TR component, or, is adapted to the hole of the connector connection end.

[0125] At the same time, by controlling the length of a section on the right side of the top column 540, the right side of the top column 540 has a more appropriate tightening force and tightening strength.

[0126] like Figure 7 As shown, the figure shows another push column 540, which is divided into two sections, wherein the right section is an external thread section, and the left section is a tightening section. The push column 540 is threadedly connected to the threaded hole at the front end of the spring push pin 530 through the external thread on the right side.

[0127] This type of top post 540 is suitable for the case where the connector extends from the hole of the multi-channel TR component. In some scenarios, a hole is provided on the left side of the top post 540, and the diameter of the hole matches the diameter of the connector. In other words, the left side diameter matches the diameter of the connector. At the same time, by controlling the length of the left side, the left side of the top post 540 has a more appropriate tightening force and tightening strength.

[0128] like Figure 8 As shown, the figure shows another top column 540, which is a cube and has two holes on its left side. The front ends of two spring ejectors 530 are inserted into the two holes and connected to the top column 540.

[0129] The right side of the top column 540 is adapted to the long strip connector.

[0130] In some embodiments, the positioning hole and the fixing hole are both long holes extending along a first direction, and the first direction is a direction perpendicular to the axis of the sliding rod;

[0131] The first fixing column 320 includes a cap and a column body integral with the cap, the length of the cross section of the column body is shorter than the axial length of the long hole, and the width of the cross section of the column body is loosely matched with the width of the long hole.

[0132] In some embodiments, the cross section of the positioning groove 211 is rectangular, and grooves with major arcs are provided at the four corners of the rectangle.

[0133] For example, Fig. 9 As shown, in some cases, the cross-section of the positioning groove 211 is rectangular, and grooves with major arcs are provided at the four corners of the rectangle, thereby avoiding the problem that the rectangular blind groove is difficult to be processed into sharp corners, resulting in the multi-channel TR component being unable to be placed in the groove, or the rectangular blind groove is processed larger in size because the rectangular blind groove is difficult to be processed into sharp corners, resulting in inaccurate positioning of the multi-channel TR component.

[0134] In other cases, the first fixing column 320 has a cap and a column integrally formed with the cap, and the cross-section of the column is an elongated strip. At the same time, the positioning hole of the chassis 210 and the fixing hole of the ejector assembly 310 are long holes, and the extension direction of the long hole is perpendicular to the axis of the sliding column. In this way, the problem of difficult alignment or partial alignment of the positioning hole and the fixing hole can be avoided.

[0135] In addition, in some scenarios, there are multiple hollows below the positioning slots 211 of the chassis 210, so that the multi-channel TR components can be easily put in and taken out.

[0136] In some other scenarios, a plurality of hollows are provided below the chassis 210 directly opposite the top column 540 to facilitate installation and removal of the top column 540 .

[0137] When used, the assembly is performed through the following steps: 1. Fix the second fixing column 410 on the chassis 210. 2. Screw the sliding rod body 420 onto the second fixing column 410. 3. Place the assembly to be welded in the positioning groove 211 of the chassis 210. 4. Fix the spring ejector pin 530 together with the first fixing plate 510 and the second fixing plate 520. 5. Install the polytetrafluoroethylene ejector column 540 on the spring ejector pin 530. 6. Slide along the sliding rod onto the chassis 210. 7. Insert the first fixing column 320.

[0138] After the above steps are completed, the connector flush with the top column 540 or sunken into the component surface has been supported by the polytetrafluoroethylene top column 540, and the connector exposed on the component surface is limited and supported by the polytetrafluoroethylene top column 540.

[0139] Put the above whole into the welding furnace to complete the connector welding.

[0140] The above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
