Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a high-performance, high-reliability bendable connector. Background Technology
[0002] Currently, there are two common structures for soldered printed circuit board (PCB) bend connectors on the market. The first structure is the conventional bend connector, where two mutually perpendicular inner conductors are connected by lap soldering. To facilitate soldering, the inner conductors often have a significant diameter change. Signal reflection occurs at the diameter change point, which degrades electrical performance. The shape of the solder joint also affects the connector's electrical performance. This type of connector is generally used less frequently. The second structure is an inner conductor bending method. To facilitate insertion into the inner hole of the outer conductor, one end of the inner conductor is often bent and then inserted into the other end. Since there is no diameter change or solder joint, its usage frequency and electrical performance are comparable to straight connectors in the same series. However, because the bent part of the inner conductor needs to pass through the inner hole of the outer conductor, the length of the bent part is often shorter, making bending difficult. Consequently, the length of the bent insertion part is also shorter. In addition, the misalignment during assembly of the insertion part leads to even less insertion at the bent part. This results in poor shock and vibration resistance and lower reliability of the product. Utility Model Content
[0003] The purpose of this invention is to provide a high-performance, high-reliability bendable connector to solve the aforementioned technical problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A high-performance, high-reliability bent connector includes an inner conductor, an insulator one, an insulator two, an outer conductor, and a cover. The inner conductor is a one-piece bent structure without diameter change and is installed in the inner holes of insulator one and insulator two. Insulator one and insulator two are respectively in horizontal and vertical positions and are respectively fixed in the inner hole of the outer conductor by barbs. The outer conductor of the connector is a one-piece bent structure. The cover is embedded in the right end hole of the outer conductor and is laser welded to the outer conductor. The left end of the horizontal position of the connector is a standard connector interface, and the lower end of the vertical position is for welding four cylinders and microstrip of the printed circuit board.
[0006] Preferably, the horizontal portion of the inner conductor is fully embedded in the inner hole of insulator one, and its left end face is flush with the left end face of insulator one. The upper half of the vertical portion of the inner conductor is inserted into the inner hole of insulator two, and the lower half extends out of the end face of insulator two.
[0007] Preferably, the right end face of the first insulator and the upper end face of the second insulator are 45° inclined surfaces that fit together, and the lower end face of the second insulator is flush with the end face of the inner hole of the outer conductor.
[0008] Preferably, the left end of the outer conductor in the horizontal position is a standard connector interface, the middle is a through hole for insulator installation, the vertical position of the outer conductor is a blind hole for insulator installation, both the through hole and the blind hole are provided with barbs for inserting insulators, the lower end of the outer conductor consists of four cylinders soldered to the outer conductor of the printed circuit board, and the right end of the outer conductor has a circular hole and slot that connect to the inner holes of insulator one and insulator two to facilitate the installation of the inner conductor, the width of the slot is greater than the diameter of the inner conductor.
[0009] Preferably, the cover is circular with a tail, the circular cover is pressed into the circular hole of the outer conductor, the tail of the cover is embedded in the groove, and the cover and the outer conductor are laser welded together to achieve the sealing of the outer conductor.
[0010] Compared with existing technologies, this utility model has the following advantages: The inner conductor of this utility model is a one-piece bent structure without diameter change. It is inserted into the inner hole of the outer conductor through a circular hole and slot at the right end of the outer conductor that communicate with the inner hole of the outer conductor. A laser welding fusion sealing process is used to weld the cap, which has the same size as the circular hole and slot of the outer conductor, together with the outer conductor, thus achieving the sealing of the outer conductor.

The inner conductor 1 is a one-piece bent structure without diameter change and is installed in the inner holes of the insulator 1 2 and the insulator 2 3. The insulator 1 2 and the insulator 2 3 are respectively in horizontal and vertical positions and are respectively fixed in the inner hole of the outer conductor 4 by barbs. The outer conductor 4 of the connector is a one-piece bent structure. The cover 5 is embedded in the right end hole of the outer conductor 4 and is laser welded to the outer conductor 4. The left end of the horizontal position of the connector is a standard connector interface, and the lower end of the vertical position is for welding four cylinders and microstrip of the printed circuit board.
[0018] The horizontal portion of the inner conductor 1 is fully embedded in the inner hole of the insulator 2, and its left end face is flush with the left end face of the insulator 2. The upper half of the vertical portion of the inner conductor 1 is inserted into the inner hole of the insulator 3, and the lower half extends out of the end face of the insulator 3.
[0019] The right end face of insulator 2 and the upper end face of insulator 3 are 45° inclined surfaces that fit together, and the lower end face of insulator 3 is flush with the end face of the inner hole of the outer conductor 4.
[0020] The outer conductor has a standard connector interface at its left horizontal position and a through hole for insulator insertion in the middle. The outer conductor also has a blind hole for insulator insertion at its vertical position. Both the through hole and the blind hole are provided with barbs for inserting insulators. The lower end of the outer conductor consists of four cylinders that are soldered to the outer conductor 4 of the printed circuit board. The right end of the outer conductor has a circular hole and a slot that facilitates the insertion of the inner conductor 1 and connects to the inner holes of insulator 1 2 and insulator 2 3. The width of the slot is greater than the diameter of the inner conductor 1.
[0021] The cover 5 is circular with a tail. The circular cover 5 is pressed into the circular hole of the outer conductor, and the tail of the cover 5 is embedded in the groove. The cover 5 and the outer conductor 4 are integrated by laser welding A to achieve the sealing of the outer conductor 4.
[0022] In this connector assembly, the inner conductor 1 is inserted into the inner hole of the outer conductor 4 through the round hole and slot on the right end face of the outer conductor 4. Then, insulator 1 2 is inserted into the inner hole of the outer conductor 4 from the left end, and insulator 2 3 is inserted into the inner hole of the outer conductor 4 from the lower end. During assembly, ensure that the 45° beveled surfaces of insulator 1 2 and insulator 2 3 are in contact with each other. Then, press the cover 5 into the outer conductor 4 from the right end and weld the cover 5 to the outer conductor 4 using laser welding A, thus sealing the outer conductor 4. The inner conductor 1 of this invention has an integral bent structure, which avoids the low frequency of use of the two-inner-conductor lap welding method, solves the problems of poor impact and vibration resistance and low reliability of the two-inner-conductor plug-in connection, and also solves the problems of short bending length and difficult bending processing.
