Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a mounting structure for differential pair contacts. Background Technology

[0002] Circular connectors are a common type of electrical connector. Their housings are typically cylindrical, and they feature a circular mating interface design, making them widely used in applications requiring reliable electrical connections. Their cylindrical housing design incorporates threads (or other locking mechanisms) to ensure a secure mating and resistance to vibration and shock. Multi-pin configurations with contacts arranged in a ring shape support signal, power, data, and even mixed transmissions (such as power + signal composites). They are widely used in industrial equipment: robots, PLCs, sensors, motor control; military / aviation: equipment with high reliability requirements (such as fighter jets and ship communication systems); medical equipment: medical imaging equipment and monitoring equipment; transportation: signal and power connections for automobiles and rail transit; and energy sectors: outdoor connections for wind power and solar energy equipment, among other fields.

[0003] Existing contact components are generally installed by directly inserting them into the mounting holes of the insulator. To ensure a secure installation, the mounting holes are usually stepped, which takes up more space compared to straight holes. This results in fewer contact components installed per unit area on the insulator, leading to lower density. When multiple contact components are required, the volume of the insulator needs to be larger, resulting in larger connectors that fit the insulator, which is inconvenient to use. In addition, since the contact components are usually fixed into the insulator in advance, the stripping length is longer when installing the circuit, making it inconvenient to twist the wires. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mounting structure for differential pair contacts, featuring an interference fit with a tapered flange. This eliminates the need for stepped holes, increases the density of contacts, reduces the volume of the mounting structure, and allows for the installation of wires on the contacts before connecting them to the insulator. This reduces the stripping length, improves the protection of the wires, and facilitates twisting, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mounting structure for differential pair contacts, comprising an insulator, mounting holes formed on the insulator, and contacts inserted into the mounting holes. A connector housing is provided on the outside of the insulator. The two ends of the mounting holes penetrate the insulator. Multiple mounting holes are provided on the insulator and are irregularly arranged. The contacts are columnar and have a tapered flange and a first limiting flange. A locking block is provided on the outside of the insulator. A locking groove is provided on the inner wall of the connector housing. A stepped flange is provided on the outer surface of the front end of the insulator. A stepped hole is provided on the inner wall of the connector housing. The stepped flange of the insulator is engaged with the stepped hole of the connector housing.

[0006] Preferably, the end of the contact has an electroplating through hole, which is connected to the interior of the contact, and the diameter of the contact inserted into the mounting hole is the same as the inner diameter of the mounting hole.

[0007] Preferably, the tapered flange is disposed on the outer surface of the end of the contact that is inserted into the mounting hole, and the tapered flange is interference-fitted with the inner wall of the mounting hole of the insulator.

[0008] Preferably, the insulator has multiple vent holes inside, which are located at the edge of the insulator and are distributed in a circumferential array.

[0009] Preferably, the first limiting flange is disposed between the electroplated through hole and the tapered flange, the inner side of the first limiting flange abuts against the outer surface of the mounting hole, and the inner side of the first limiting flange is bonded to the surface of the insulator.

[0010] Preferably, the length of the contact element is less than the length of the mounting hole, and the length of the contact element located behind the first limiting flange is less than the length located in front of the first limiting flange.

[0011] This utility model provides a mounting structure for differential pair contacts, which has the following advantages: 1. The mounting structure of the differential pair contact, through the setting of the tapered flange on the outside of the contact, allows for a tight connection between the tapered flange and the inner wall of the mounting hole during use. The tapered flange also facilitates the contact to enter the mounting hole easily, but makes it inconvenient to pull it out of the mounting hole, thus improving the stability of the connection.

[0012] 2. The mounting structure of this differential pair contact has a through-hole design, which allows for more mounting holes per unit area of ​​the insulator during use. This increases the density of the contacts, resulting in a smaller mounting structure and easier use.

[0013] 3. The mounting structure of the differential pair contact is designed with the mounting hole and the contact being plugged in. This allows the wire to be installed first and then inserted into the mounting hole, resulting in less wire stripping and better protection for the wire. It also allows the wire to be twisted, making wire installation more convenient. Attached Figure Description

[0016] 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.

[0017] Example Please see Figures 1 to 4 This utility model provides a technical solution for a differential pair contact mounting structure, including an insulator 1, mounting holes 2 formed on the insulator 1, and a contact 3 inserted into the mounting holes 2. A connector housing 9 is provided on the outside of the insulator 1. The two ends of the mounting holes 2 penetrate the insulator 1. Multiple mounting holes 2 are provided on the insulator 1 and are irregularly arranged. The contact 3 is columnar and has a tapered flange 4 and a first limiting flange 5. A locking block 8 is provided on the outside of the insulator 1. A locking groove 10 is provided on the inner wall of the connector housing 9. A stepped flange is provided on the outer surface of the front end of the insulator 1. A stepped hole is provided on the inner wall of the connector housing 9. The stepped flange of the insulator 1 is engaged with the stepped hole of the connector housing 9.

[0018] The tapered flange 4 is provided on the outer surface of one end of the contact 3 that is inserted into the mounting hole 2, and the tapered flange 4 and the inner wall of the mounting hole 2 of the insulator 1 are interference fit.

[0019] Specifically, when installing contact 3, it is necessary to first connect wires to contact 3, with the ends of the wires connected to the front end of contact 3 and the wires twisted together. Then, the front end of contact 3 is inserted into the mounting hole 2 of insulator 1. During installation, the tapered flange 4 on contact 3 is in a curved fit with the inner wall of mounting hole 2. Since insulator 1 is an insulating material, which is commonly made of rubber, the tapered flange 4 can easily enter the mounting hole 2. However, when the tapered flange 4 is pulled out of the mounting hole 2, due to the structural shape of the tapered flange 4, it is inconvenient to pull it out of the mounting hole 2. While improving the convenience of installation, it also increases the difficulty of pulling it out, thus improving the installation firmness. After inserting multiple contacts 3 into the mounting holes 2 one by one, the insulator 1 is then installed into the connector housing 9. Since the insulator 1 has a locking block 8 on its outside and the connector housing 9 has a locking groove 10 inside, during installation, the locking block 8 needs to be aligned with the locking groove 10 so that the locking block 8 is inserted into the locking groove 10. This facilitates the connection and fixation between the insulator 1 and the connector housing 9 and prevents the insulator 1 from rotating inside the connector housing 9.

[0020] The end of the contact 3 is provided with an electroplating through hole 6, which is connected to the interior of the contact 3. The diameter of the contact 3 inserted into the mounting hole 2 is the same as the inner diameter of the mounting hole 2.

[0021] Specifically, since the diameter of the contact 3 inserted into the mounting hole 2 is the same as the inner diameter of the mounting hole 2, compared with the traditional stepped hole, the number of mounting holes 2 per unit area of ​​the insulator 1 can be increased, thereby increasing the density of the contact 3. When the same contact 3 is required, this mounting structure is smaller in size and can be used in smaller installation spaces, improving ease of use. In addition, the electroplating through-hole 6 is designed to make it easier for the gold plating solution to enter the interior of the contact 3 during gold plating, thereby improving the gold plating effect.

[0022] The insulator 1 has multiple vent holes 7 inside, which are located at the edge of the insulator 1 and are distributed in a circular array.

[0023] Specifically, the vent 7 allows air to pass through, which reduces the overall effective dielectric constant of the dielectric region between the pins, thereby increasing the signal propagation speed.

[0024] The first limiting flange 5 is disposed between the electroplated through hole 6 and the tapered flange 4. The inner side of the first limiting flange 5 abuts against the outer surface of the mounting hole 2, and the inner side of the first limiting flange 5 is bonded to the surface of the insulator 1. The length of the contact 3 is less than the length of the mounting hole 2, and the length of the contact 3 located behind the first limiting flange 5 is less than the length located in front of the first limiting flange 5.

[0025] Specifically, after the contact 3 is installed inside the mounting hole 2, the first limiting flange 5 of the contact 3 is connected to the end of the mounting hole 2 with adhesive to further reinforce it.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
