Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a multi-channel electrical quick-change connector device. Background Technology

[0002] With the development of the electrical connector field, various electrical connectors and hybrid connectors have been widely used. However, these products still have some problems in practical use. For example, most pneumatic connectors and electrical connectors on the market are currently designed independently. Even if some products have achieved integration (i.e., hybrid connectors), their structure is complex and their adaptability is poor, making it difficult to meet the universal requirements of different models of equipment. In addition, connectors in existing technologies still have shortcomings in terms of quick-change function, ease of installation, and cost control, which limits their efficient application in multiple scenarios.

[0003] A prior art patent document with publication number CN116635106B, published on November 19, 2024, discloses a connector. This design achieves simultaneous transmission of fluid and electrical signals by incorporating a fluid flow channel, a socket, and a plug. While this structure can meet the multi-functional requirements of specific scenarios, its connection method relies on a complex alignment mechanism, resulting in low assembly efficiency and high requirements for the operating environment. Furthermore, this design does not adequately consider the compatibility issues of different equipment models; therefore, in practical applications, different connector structures need to be customized according to the equipment model, increasing manufacturing costs and maintenance difficulty.

[0004] Another patent document, CN108281834B, discloses a connector socket, published on May 14, 2024. This design, by bending the socket housing and employing a split-type plug-in shielding shell, effectively saves installation space and improves wiring flexibility. However, the main application scenarios for this design are still limited to a single type of electrical connection, lacking support for pneumatic circuits and other media transmission. Furthermore, while its split-type plug-in design facilitates processing and assembly, it is prone to poor contact during frequent plugging and unplugging, affecting long-term reliability.

[0005] Therefore, a multi-channel electrical quick-change connection device needs to be designed to solve the above problems. Utility Model Content

[0016] Reference Figures 1 to 4 A multi-channel electrical quick-change connection device, comprising: The upper connection unit 1 includes an upper housing 3, an electrical connection module 5 disposed within the upper housing 3, and a fluid channel module 6. The lower connection unit 2 includes a lower housing 4, an electrical docking module 7 and a fluid docking module 8 disposed within the lower housing 4; The electrical connection module 5 and the electrical docking module 7 are arranged vertically to form an electrical connection path; The fluid channel module 6 and the fluid docking module 8 are aligned vertically to form a fluid transmission path.

[0017] The upper housing 3 and the lower housing 4 are quickly aligned and positioned through the guide groove 16 and the guide protrusion 17, and are locked in a secondary manner through the locking mechanism 14 and the fixing block 15, thereby ensuring a stable connection between the two.

[0018] In another implementation, a sealing gasket is also included. The sealing gasket is placed between the upper housing 3 and the lower housing 4. When the two are joined, it is compressed and deformed to fill the gap and prevent external dust or liquid from entering.

[0019] The fluid channel module 6 mainly consists of a mounting plate, a vent column 9, a clamping plate 11, and an elastic sealing ring 10. The vent column 9 passes through a positioning hole on the mounting plate and is limited by the clamping plate 11, which is connected to the mounting plate by bolts. The position and range of motion of the vent column 9 within the positioning hole can be adjusted by tightening or loosening the bolts. An elastic sealing ring 10 is fitted around the outer periphery of the vent column 9 and is placed within the positioning hole of the mounting plate. The elastic sealing ring 10 is made of a highly elastic material and can deform under external force, thus enabling the vent column 9 to have a flexible adjustment function. An additional sealing ring 12 is also provided on the outer periphery of the bottom of the vent column 9 for a tight fit with the connecting pipe in the fluid docking module 8 to prevent fluid leakage.

[0020] The fluid docking module 8 mainly includes a docking plate 81, docking holes, a connecting pipe 82, and a limiting plate 83. The connecting pipe is embedded in the docking hole and tightly fitted with the docking hole through an elastic seal, while being fixed in position by the limiting plate. The fluid docking module mainly includes a docking plate, several sets of docking holes disposed on the docking plate, connecting pipes respectively installed in the docking holes, and a limiting plate installed on the docking plate to limit the connecting pipes. The connecting pipe is installed in the docking hole of the docking plate through a lower sealing ring 84. The sealing ring itself is made of elastic material, so it has a certain degree of elasticity and elastic deformation capability. When the connecting pipe is subjected to force, it can be squeezed, thereby giving the connecting pipe a certain degree of flexible adjustment function to achieve the purpose of automatic insertion. The flexible adjustment function of the connecting pipe matches the vent column 9, so that the two can automatically calibrate and fit tightly during the docking process.

[0021] The electrical connection module 5 includes a conductive pin, an insulating protective layer, and a pin holder. The conductive pin is fixed to the inner wall of the upper housing via the pin holder and extends vertically. The top end of the conductive pin is connected to an external power source or signal source, while the bottom end contacts the conductive contacts in the electrical docking module 7. The electrical docking module 7 includes conductive contacts, an insulating isolation layer, and a contact holder. The conductive contacts are fixed to the inner wall of the lower housing 4 via the contact holder and are distributed correspondingly to the conductive pin. When the upper connection unit 1 docks with the lower connection unit 2, the conductive pin and the conductive contacts form a stable electrical connection path.

[0022] The locking mechanism 14 is mounted on both sides of the upper housing 3 via a rotating shaft, while the fixing blocks 15 are located on both sides of the lower housing 4. After the upper connecting unit 1 and the lower connecting unit 2 are docked, the locking mechanism 14 is flipped to engage with the fixing blocks 15, thereby forming a secondary lock to prevent the connection from becoming loose due to vibration or external force.

[0023] Both the upper housing 3 and the lower housing 4 have anti-slip textured surfaces. The textured surfaces are uneven to increase grip and facilitate disassembly and installation. The upper housing 3 and the lower housing 4 are made of high-strength engineering plastic, which has good corrosion resistance and impact resistance, extending their service life.

[0024] In practical applications, the multi-channel electrical quick-change connection device of this utility model is suitable for a variety of scenarios, such as industrial automated production lines, medical equipment or laboratory instruments, where frequent equipment replacement is required.

[0025] The operator selects the lower connecting unit 2 that matches the new equipment by observing the lower housing 4. The equipment model and connection parameters are clearly marked for quick identification of the compatible components. Then, the lower connecting unit 2 of the old equipment is unlocked from the upper connecting unit 1. During unlocking, the locking mechanism 14 is flipped to disengage from the fixing block 15, releasing the secondary locking state and thus separating the upper connecting unit 1 from the lower connecting unit 2. During this process, the locking mechanism 14 is mounted on both sides of the upper housing 3 via a rotating shaft, and the fixing blocks 15 are located on both sides of the lower housing 4, ensuring simple and reliable locking and unlocking operations.

[0026] Next, the operator aligns the guide protrusion 17 of the lower connecting unit 2 of the new equipment with the guide groove 16 of the upper connecting unit 1 and inserts it. The design of the guide groove 16 and the guide protrusion 17 guides them to align quickly and reduces docking errors. When the guide protrusion 17 is fully inserted into the guide groove 16, the upper connecting unit 1 and the lower connecting unit 2 enter the initial docking state. At this time, the vent column 9 begins to contact the connecting pipe. The elastic sealing ring 10 sleeved on the outer periphery of the vent column 9 deforms when subjected to external force, giving the vent column 9 a flexible adjustment function, thereby automatically calibrating and tightly fitting the connecting pipe. The sealing ring at the bottom of the vent column 9 further enhances the fitting effect and prevents fluid leakage. At the same time, the conductive pin 12 and the conductive contact 13 form a stable electrical connection path during the upper and lower docking process, ensuring reliable transmission of electrical signals.

[0027] After the initial docking is completed, the operator flips the locking mechanism 14 to engage with the fixing block 15, forming a secondary lock. This design enhances the connection stability through mechanical locking, preventing loosening due to vibration or external force.

[0028] The advantages of this utility model are that, through modular design, electrical connection and fluid transmission are integrated into one device, reducing the complexity and assembly difficulty caused by independent design; the flexible combination of the upper and lower connection units can adapt to the needs of different models of equipment, significantly improving adaptability and versatility. By incorporating a vent column and connecting pipe with flexible adjustment function, the problem of poor contact that easily occurs in traditional connectors during frequent insertion and removal is solved; the double sealing design of elastic sealing ring and sealing ring effectively prevents fluid leakage and ensures the reliability of the transmission process.

[0029] 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.
