Description

Technical Field

[0001] This utility model relates to the field of connector equipment, specifically to a low-frequency twin structure for printed circuit board connections. Background Technology

[0002] With the rapid development of current technologies such as aviation, aerospace, weaponry, and radar, the requirements for the performance and application environment of connectors are becoming increasingly stringent. Connectors must not only meet the basic requirements for reliable interconnection of electrical circuits, but also, due to the diversification of application environments, possess functions such as high density, lightweight, integrated modules, hermetic sealing, easy disassembly, high temperature resistance, vibration resistance, and shock resistance.

[0003] Existing board-to-board interconnect connectors can achieve reliable interconnection of electrical circuits without meeting the requirements of high-density integration. However, they have certain drawbacks in practical applications. For example, in high-density, integrated socket applications, traditional board-to-board interconnects are generally used for single-pair interconnects. However, when installing single-pair interconnects, multiple sets of connectors need to be aligned and installed one by one. Installing multiple sets of connectors one by one is time-consuming and error-prone, and cannot meet the integration requirements of modern equipment. Utility Model Content

[0004] In view of this, the present invention provides a low-frequency twin structure for printed circuit board connection, which can be connected to the socket on the device by using a connector that communicates with multiple storage cavities, thereby completing the connection of multiple connectors and sockets at once and reducing the inconvenience of one-to-one connection.

[0005] To solve the above-mentioned technical problems, this utility model provides a low-frequency twin structure for printed circuit board connection, including a housing, wherein the housing has two storage spaces, each of which is disposed through the housing and can be used to place a pin assembly. The pin assembly is used for the transmission of electrical circuit signals, and the housing is used to protect the pin assembly placed in the storage cavity and prevent the pin assembly from being damaged, which would result in poor transmission of electrical circuit signals.

[0006] The pin assembly includes part a, which is located at the end of the pin assembly and is used to connect with the pin. Part a is located in the storage cavity and a limiting seat is provided in the storage cavity. The limiting seat has several circular holes with the same diameter as the pin assembly. Part a passes through the circular holes on the limiting seat and is fixed in the storage cavity.

[0007] The further limiting seat can be divided into limiting seat one and limiting seat two. Limiting seat two is located below limiting seat one. A first potting area is reserved between limiting seat one and limiting seat two. Potting glue in the first potting area can not only connect limiting seat one and limiting seat two, but also prevent the pin assembly from moving up and down in the round hole. This would cause the a part of the pin assembly to move downward under force when it is connected to the pin on the socket, and the a part cannot be connected to the pin.

[0008] The housing end has a connector that communicates with the storage cavity. The connectors are located on both sides of the housing and are symmetrical about the center of the housing. There is a groove in the middle of the two connectors. The two connectors on one housing facilitate the connection of two sockets at one time. The length of the connector protrusion can be determined by controlling the length of the groove in the middle of the connector, so as to avoid over-positioning when the head and base are inserted.

[0009] Below the pin assembly a, there is also a b part. The b part protrudes from the tail of the housing and has a printed circuit board. The printed circuit board is located below the limiting seat and abuts against the tail of the housing to make the cavity a sealed space. A second potting area is formed between the printed circuit board and the limiting seat. Glue is poured into the second potting area to seal the inside of the housing and fix the part of the pin assembly b part that is not fixed by the limiting seat, so as to prevent the pin assembly from shaking.

[0010] The bottom of the housing is symmetrically equipped with limiting pins, and both ends of the printed circuit board have holes with the same diameter as the limiting pins. The length of the limiting pins is greater than the length of part b of the pin assembly. When installing the printed circuit board, align the holes on the printed circuit board with the limiting pins and move it downwards so that the printed circuit board abuts against the tail of the housing to complete the installation of the printed circuit board. Using the limiting pins to guide the printed circuit board can effectively prevent the printed circuit board from colliding with the pin assembly, and the symmetrically arranged limiting pins can effectively prevent the printed circuit board from shaking during movement.

[0011] The printed circuit board is equipped with fasteners, including threaded holes at the tail of the housing, which are located between symmetrically arranged limit pins. The printed circuit board is also equipped with fastening bolts that pass through the printed circuit board and connect to the threaded holes to fix the printed circuit board.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. Improved connection efficiency: By setting up connectors that connect to the two storage cavities, the two connectors can be inserted into the two sockets at once by holding the housing. Compared with the traditional single-pair interconnection method, it reduces the operation of aligning and installing multiple sets of connectors one by one, avoiding time-consuming and error-prone situations, and adapting to the integration needs of modern equipment.

[0014] 2. Ensure connection stability: The limiting seat in the storage cavity has a round hole to fix part a of the pin assembly. Glue is poured into the second potting area between the printed circuit board and the limiting seat to fix the part of the pin assembly b that is not fixed by the limiting seat, so as to prevent the pin assembly from shaking and further ensure connection stability.

[0015] 3. Protection of internal components: The housing protects the pin assembly placed inside the storage cavity from damage, ensuring normal transmission of electrical circuit signals. The printed circuit board abuts against the rear of the housing, creating a sealed space inside the storage cavity and reducing the impact of external factors on the internal components.

[0016] 4. Easy Installation: Symmetrical limit pins are located at the bottom of the housing, and holes with the same diameter as the limit pins are located at both ends of the printed circuit board. During installation, the limit pins guide the printed circuit board, preventing collisions with the pin assembly. The symmetrically arranged limit pins also prevent the printed circuit board from wobbling during movement. Fasteners are provided on the printed circuit board, which connect to the threaded holes at the rear of the housing via bolts for easy securing. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] like Figure 1 ,3 As shown in Figure 4:

[0024] This embodiment provides a low-frequency twin structure for printed circuit board connection, including a housing 1. The housing 1 is generally concave. The hollow structure inside the housing 1 forms a storage cavity, which is used to place a pin assembly 100 for transmitting electrical signals. The pin assembly 100 is a connector 4 protruding from both sides of the end of the housing 1. The connector 4 is connected to the storage cavity and is used to connect to a socket.

[0025] like Figure 2 , 3 As shown in Figure 4:

[0026] The storage cavity is provided with a limiting seat 5. The end of the limiting seat 5 is located in the connector 4 that is connected to the housing 1. The limiting seat 5 is provided with several round holes 3. The pin assembly 100 in the storage cavity passes through the round holes 3 on the limiting seat 5 and is fixed in the storage cavity by the limiting seat 5.

[0027] like Figure 3 , 4 As shown:

[0028] The limiting seat 5 is divided into limiting seat 5-1 and limiting seat 5-2. The limiting seat 5-1 is T-shaped and is located inside the connector 4. The pin assembly 100 includes a part 101, which is fixed inside the connector 4 by the limiting seat 5-1 to facilitate connection with the pins inside the socket. The limiting seat 5-2 is located inside the storage cavity and below the limiting seat 5-1. It is used to limit and support the middle part of the pin assembly 100 to prevent the pin assembly 100 from shaking inside the storage cavity. A first injection cavity is left between the limiting seat 5-1 and the limiting seat 5-2.

[0029] like Figure 1 , 3 As shown in Figure 4:

[0030] Injecting a certain amount of resin glue into the first injection cavity can effectively reinforce the pin assembly 100 within the storage cavity and prevent the pin assembly 100 from moving up and down within the storage cavity.

[0031] like Figure 1 , 2 As shown in Figure 4:

[0032] Below the pin assembly 100a part 101, there is also a b part 102. The b part 102 protrudes from the outside of the housing 1. A printed circuit board 6 is connected to the b part 102. The printed circuit board 6 is cuboid in shape. The side base surface of the printed circuit board 6 is tightly fitted to the bottom of the housing 1, which can complete the sealing operation of the inside of the housing 1. Sealing the inside of the housing 1 and injecting glue can ensure the dryness of the inside of the housing 1 and also provide dust protection.

[0033] like Figure 1 , 4 As shown:

[0034] Two guide pins are provided at one end of the housing 1 near the printed circuit board 6. The length of the guide pins is greater than the length of the pin assembly 100. Three threaded holes are arranged inside the housing 1. The guide pins are provided with external threads at one end near the threaded holes. The guide pins are rotated and set in the threaded holes at both ends of the three threaded holes through the external threads. The guide pins are connected by threads to facilitate the disassembly of the guide pins and prevent the guide pins from being too long, which would make it difficult to install subsequent components onto the printed circuit board 6.

[0035] like Figure 3 , 4 As shown:

[0036] The printed circuit board 6 has an opening parallel to the threaded hole. After the printed circuit board 6 is installed to fit against the bottom of the housing 1 by the guide pin, a fastening bolt is installed in the threaded hole at the center of the housing 1. The fastening bolt is passed through the opening at the center of the printed circuit board 6 to fix the printed circuit board 6 to the housing 1.

[0037] Working principle: When in use, first insert the pin assemblies 100 one by one into the round holes 3 on the limiting seat 5, and align the two ends of the pin assemblies 100. Then, place the limiting seat 5 with the pin assemblies 100 into the storage cavity inside the housing 1, and fill the bottom of the limiting seat 5 with resin glue that is flush with the bottom of the housing 1. Then, the printed circuit board 6 is placed into the tail end of the pin assembly 100 through the guide of the limiting pin 7, and the printed circuit board 6 is fixed to the housing 1 by the fastener 8.

[0038] Furthermore, it should be noted that, in the description of this utility model, 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 according to the specific circumstances.

[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
