Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a multi-port connector. Background Technology

[0002] With the rapid development of the rail transit industry, high-speed trains are placing higher demands on the reliability, efficiency, and ease of operation of their end connectors. End connectors are primarily used for inter-vehicle network, signal, and power transmission, and are key components ensuring the safe and stable operation of trains. Currently, rectangular connectors are widely used in the rail transit field, requiring them to meet stringent requirements for high integration, multi-signal transmission, and adaptability to harsh environments.

[0003] In existing technologies, vehicle-end connectors generally adopt a single-port plug-socket structure, using bolts to achieve mechanical connection and electrical conduction. While this structure offers a certain degree of integration, it has significant drawbacks in practical applications: First, during vehicle coupling operations, the single port on each socket results in a heavy plug, requiring operators to expend considerable physical effort to plug and unplug, increasing operational difficulty and time. Second, when bolted connections are installed within the limited space of the vehicle end, thread scratches are prone to occur, affecting connection reliability and increasing maintenance costs.

[0004] Therefore, there is an urgent need to provide a multi-port connector to address the problems existing in the prior art to some extent. Utility Model Content

[0005] The purpose of this invention is to provide a multi-port connector to optimize the connector structure to a certain extent and solve the problem that the high integration of a single plug results in a large weight and inconvenience in plugging and unplugging.

[0006] This utility model provides a multi-port connector, including a socket, a first plug, a second plug, and a connecting wire. The socket includes a main housing and a secondary housing. The main housing forms a first port and a second port. A first plug-in module is provided in the first port, and a second plug-in module is provided in the second port. The first plug is plugged into the first plug-in module, and the second plug is plugged into the second plug-in module. The main housing has a positioning hole corresponding to the position of the secondary housing. The secondary housing is inserted into the positioning hole, and the secondary housing is sealed to the main housing. The connecting end of the connecting wire enters through the secondary housing and connects to the first plug-in module and the second plug-in module.

[0007] The first port and the second port are respectively provided with a quick-connect mechanism between the first plug and the second plug; the quick-connect mechanism includes a ball lock assembly and a cap assembly. The ball lock assembly includes a plurality of steel balls. Both the first port and the second port have a plurality of radially penetrating through-walls in their circumferential directions. The plurality of steel balls are slidably disposed in the radially penetrating through-walls in the communicating grooves. The cap assembly includes a cap body. Both the first plug and the second plug include a housing. The cap body is slidably disposed outside the housing. The housing has a receiving groove for receiving the steel balls.

[0008] Specifically, the hood assembly further includes a spring, a first limiting portion is formed on the inner wall of the hood body, and a second limiting portion is formed on the outer wall of the outer shell. The first limiting portion and the second limiting portion cause the hood body and the outer shell to form a receiving cavity. The spring is sleeved on the outer shell and located in the receiving cavity. The two ends of the spring abut against the first limiting portion and the second limiting portion, respectively.

[0009] Furthermore, an opening groove is formed on the outer shell, and a cotter pin is connected to the cap body at the position corresponding to the opening groove. The spring extends and drives the cotter pin to be inserted into the opening groove, thereby limiting the axial position of the cap body relative to the outer shell.

[0010] The multi-port connector provided in this application further includes a shielding component, which includes a first shielding frame and a frame. The first shielding frame is disposed inside the main housing and connected to the main housing. The connecting end of the connecting line is connected to the first shielding frame. The frame is connected to the main housing. Both the first plug-in module and the second plug-in module are connected to the frame.

[0011] The multi-port connector provided in this application also includes a seal. A sealing groove is formed circumferentially on the sub-housing. The seal is disposed in the sealing groove and is pressed between the sub-housing and the main housing to achieve a seal between the sub-housing and the main housing.

[0012] Specifically, the first plug and the second plug further include a second shielding frame, which is U-shaped and disposed inside the housing. The lines entering the first plug and the second plug are connected to the second shielding frame, and the second shielding frame is connected to the housing.

[0013] Furthermore, the first plug and the second plug also include a pin module, which is connected to the housing.

[0014] Furthermore, the socket also includes a mounting plate and an end cap; the mounting plate is used to fix the main housing to the end cap, and the end cap is sealed on the end of the main housing away from the first port and the second port.

[0015] Furthermore, the exterior of the main housing, the secondary housing, and the outer shell are all coated with an insulating layer.

[0016] Compared with existing technologies, the multi-port connector provided by this utility model has the following advantages: The multi-port connector provided by this utility model includes a socket, a first plug, a second plug, and a connecting wire. The socket includes a main housing and a secondary housing. The main housing has a first port and a second port. A first plug-in module is provided in the first port, and a second plug-in module is provided in the second port. The first plug is plugged into the first plug-in module, and the second plug is plugged into the second plug-in module. A positioning hole is formed in the main housing corresponding to the position of the secondary housing. The secondary housing is inserted into the positioning hole, and the secondary housing is sealed to the main housing. The connecting end of the connecting wire enters through the secondary housing and connects to the first plug-in module and the second plug-in module.

[0017] Analysis shows that the socket adopts a dual-port design, forming a first port and a second port, which are arranged in parallel. In actual installation, they are integrated and fixed by sharing the mounting plate, which effectively solves the problem of excessive weight of a single plug in traditional single-port connectors.

[0018] Correspondingly, the main housing has precise positioning holes corresponding to the sub-housing. The sub-housing can be inserted into the positioning holes through an interference fit to achieve precise alignment. A sealed connection is used between the sub-housing and the main housing to ensure the overall sealing performance of the connector. The connecting end of the wire enters the socket through the sub-housing and connects to the first and second plug-in modules respectively, thereby achieving circuit continuity.

[0019] Understandably, the dual-port design breaks down the traditional single heavy plug into two lighter plugs, significantly reducing the operational difficulty when coupling vehicles. At the same time, the modular structure facilitates maintenance and replacement, improving the product's maintainability. Attached Figure Description

[0032] like Figures 1-6 As shown, this utility model provides a multi-port connector, including a socket, a first plug 3, a second plug 4, and a connecting wire; the socket includes a main housing 1 and a secondary housing 2, the main housing 1 having a first port 101 and a second port 102, the first port 101 having a first insertion module 1011, and the second port 102 having a second insertion module 1021, the first plug 3 being inserted into the first insertion module 1011, and the second plug 4 being inserted into the second insertion module 1021; the main housing 1 having a positioning hole corresponding to the position of the secondary housing 2, the secondary housing 2 being inserted into the positioning hole, and the secondary housing 2 being sealed to the main housing 1; the connecting end of the connecting wire enters through the secondary housing 2 and connects to the first insertion module 1011 and the second insertion module 1021.

[0033] Compared with the prior art, the multi-port connector provided in this application has the following advantages; The multi-port connector provided in this application has a socket with a dual-port design forming a first port 101 and a second port 102. The two ports are arranged in parallel. In actual installation, they are integrated and fixed by sharing the mounting plate 8 described below, which effectively solves the problem of excessive weight of a single plug in traditional single-port connectors.

[0034] Correspondingly, the main housing 1 has a precise positioning hole corresponding to the sub-housing 2. The sub-housing 2 can be inserted into the positioning hole through an interference fit to achieve precise alignment. The sub-housing 2 and the main housing 1 can also be detachably connected by bolts. During the continuous tightening of the bolts, the sealing element 201 is compressed to achieve a sealed connection and ensure the overall sealing performance of the connector. The connecting end of the connecting wire enters the socket through the sub-housing 2 and connects to the first plug-in module 1011 and the second plug-in module 1021 respectively, thereby realizing the conduction of the circuit.

[0035] Understandably, the dual-port design breaks down the traditional single heavy plug into two lighter plugs, significantly reducing the operational difficulty when coupling vehicles. At the same time, the modular structure facilitates maintenance and replacement, improving the product's maintainability.

[0036] Optionally, such as Figures 1-4 Combination Figure 6 As shown, in this application, the first port 101 and the second port 102 are provided with a quick-plug mechanism between the first plug 3 and the second plug 4. The quick-plug mechanism includes a ball lock assembly and a cap assembly. The ball lock assembly includes a plurality of steel balls 5. A plurality of radially penetrating through-walls of the first port 101 and the second port 102 are formed in the circumferential direction of the first port 101 and the second port 102. The plurality of steel balls 5 are slidably disposed in the connecting grooves. The cap assembly includes a cap body. The first plug 3 and the second plug 4 both include a housing 301. The cap body is slidably disposed outside the housing 301. The housing 301 forms a receiving groove 3012 for receiving the steel balls 5.

[0037] The quick-release mechanism is an important feature of this utility model, comprising two parts: a ball lock assembly and a cap assembly. The ball lock assembly consists of multiple steel balls 5, and multiple radially penetrating connecting grooves are formed in the circumferential direction of both the first port 101 and the second port 102.

[0038] The steel ball 5 is slidably disposed within the communicating groove and can move freely in the radial direction. The cap assembly includes a cap body, which is slidably disposed outside the housing 301 of the first plug 3 and the second plug 4. The housing 301 is formed with a specially designed receiving groove 3012 for accommodating the steel ball 5 in the connected state.

[0039] During actual insertion, the user aligns the first plug 3 or the second plug 4 with the corresponding port of the socket (first port 101 or second port 102). The guide structure of the plug housing 301 and the tapered design of the socket inlet ensure initial alignment, reducing misoperation. At this point, the cap is in its initial position. Then, the user applies axial thrust to push the plug into the socket. As the plug penetrates deeper, the contact surface of the plug housing 301 begins to interact with the steel ball 5 of the socket, forcing the steel ball 5 to move radially within the connecting groove, exposing a portion of the steel ball 5 on the other side of the connecting groove.

[0040] When the plug is fully pushed in, the receiving groove 3012 formed by the plug housing 301 corresponds to the steel ball 5. At this time, the cap body is pushed to move axially towards the socket.

[0041] As the cap body continues to advance, it will gradually come into contact with the steel ball 5 protruding on the other side, forcing the steel ball 5 into the receiving groove 3012. By keeping the cap body in this position, the steel ball 5 can always be limited, keeping the steel ball 5 in the receiving groove 3012, thereby achieving locking between the plug and the socket.

[0042] When it is necessary to unplug the plug, pull the cap away from the socket, so that the steel ball 5 can move outward, thereby unlocking the plug and socket. Pulling the plug will separate the plug and socket.

[0043] Optionally, such as Figure 4 As shown, the hood assembly in this application also includes a spring 6. A first limiting portion 3021 is formed on the inner wall of the hood body, and a second limiting portion 3011 is formed on the outer wall of the outer shell 301. The first limiting portion 3021 and the second limiting portion 3011 make the hood body and the outer shell 301 form a receiving cavity. The spring 6 is sleeved on the outer shell 301 and located in the receiving cavity. The two ends of the spring 6 abut against the first limiting portion 3021 and the second limiting portion 3011 respectively.

[0044] Preferably, this application enables the automatic return of the cap body by further adding a spring 6 between the cap body and the outer shell 301.

[0045] The user aligns the first plug 3 or the second plug 4 with the corresponding port (first port 101 or second port 102) of the socket. The guide structure of the plug housing 301 and the tapered design of the socket inlet ensure initial alignment and reduce misoperation. At this point, the cap is in its initial position. The user then applies axial thrust to push the plug into the socket. As the plug penetrates deeper, the contact surface of the plug housing 301 begins to interact with the steel ball 5 of the socket, forcing the steel ball 5 to move radially within the connecting groove, exposing a portion of the steel ball 5 on the other side of the connecting groove.

[0046] When the plug is pushed in, the plug housing 301 forces the steel ball 5 to move outward. Since the wall of the housing 301 is always in contact with the steel ball 5, the protruding steel ball 5 will abut against the end of the cap. As the plug is continuously inserted, the cap is continuously pushed away from the socket, thereby compressing the internal spring 6.

[0047] When the plug reaches the predetermined position, that is, when the steel ball 5 is aligned with the receiving groove 3012 on the plug housing 301, the spring 6 pushes the cap towards the socket under the action of the rebound force, thereby forcing the steel ball 5 to be embedded in the receiving groove 3012, forming a mechanical lock.

[0048] After locking, the spring 6 maintains slight tension in the cap assembly, ensuring that the steel ball 5 remains embedded and preventing accidental loosening.

[0049] It is understood that the spring 6 in this application is sleeved on the outer shell 301, the inner wall of the cap has a first limiting part 3021, and the outer wall of the outer shell 301 has a second limiting part 3011. Together, they form a receiving cavity to limit the range of motion of the spring 6. The two ends of the spring 6 abut against the first limiting part 3021 and the second limiting part 3011 respectively, providing the necessary rebound force.

[0050] Optionally, such as Figure 2 Combination Figure 3 As shown, an opening groove is formed on the outer shell 301 in this application, and a cotter pin 7 is connected to the cap body at the position corresponding to the opening groove. The spring 6 extends and drives the cotter pin 7 to be inserted into the opening groove, thereby limiting the cap body relative to the outer shell 301 in the axial direction.

[0051] Since the spring 6 pushes the cap body towards the socket, by further providing an opening groove on the housing 301 and a cotter pin 7 on the cap body, the cotter pin 7 can be inserted into the opening groove when the spring 6 pushes the cap body to move axially, thereby limiting the movement of the cap body and ensuring stable movement of the cap body.

[0052] Optionally, such as Figure 3 Combination Figure 5 and Figure 6 As shown, the multi-port connector provided in this application also includes a shielding component, which includes a first shielding frame 10 and a frame. The first shielding frame 10 is disposed inside the main housing 1 and connected to the main housing 1. The connection end of the connecting wire is connected to the first shielding frame 10. The frame is connected to the main housing 1. The first plug-in module 1011 and the second plug-in module 1021 are both connected to the frame.

[0053] The shielding assembly includes a first shielding frame 10 and a frame. The first shielding frame 10 is disposed inside the main housing 1 and reliably connected to the main housing 1 by screws. The connection ends of the connecting wires are connected to the first shielding frame 10 by crimping or welding to ensure good electrical contact.

[0054] The frame is connected to the main housing 1 by snaps or screws, and the first plug-in module 1011 and the second plug-in module 1021 are both electrically connected to the frame.

[0055] The first shield 10 further provided inside the main housing 1 can provide a connection base for the connection end of the connecting wire, thereby avoiding excessive bending of the connecting wire and causing line damage to a certain extent.

[0056] Optionally, such as Figure 6 As shown, the multi-port connector provided in this application also includes a seal 201. A sealing groove 202 is formed circumferentially on the sub-housing 2. The seal 201 is disposed in the sealing groove 202 and is pressed between the sub-housing 2 and the main housing 1 to achieve a seal between the sub-housing 2 and the main housing 1.

[0057] The formed sealing groove 202 can accommodate the sealing element 201, and the sealing element 201 can achieve a sealed connection between the sub-shell 2 and the main shell 1.

[0058] Optionally, such as Figure 3As shown, the first plug 3 and the second plug 4 also include a second shielding frame 11. The second shielding frame 11 is U-shaped and is disposed inside the housing 301. The lines entering the first plug 3 and the second plug 4 are connected to the second shielding frame 11, and the second shielding frame 11 is connected to the housing 301.

[0059] This application provides a second shielding frame 11 inside the first plug 3 and the second plug 4. The second shielding frame 11 has a U-shaped structure and perfectly fits the internal contour of the outer shell 301.

[0060] The lines entering the first plug 3 and the second plug 4 are reliably connected to the second shielding frame 11, which forms a good electrical connection with the outer casing 301 through a conductive pad. When the plug and socket are mated, the shielding layer makes contact first and then disconnects through the grounding pin hole on the frame.

[0061] Optionally, such as Figure 3 As shown, the first plug 3 and the second plug 4 also include a pin module 303, which is connected to the housing 301.

[0062] The first connector module 1011 and the second connector module 1021 adopt a standardized and modular design, and different types of pin modules 303 can be flexibly configured according to actual needs. The pin module 303 is connected to the housing 301 by a snap-fit ​​connection, which facilitates quick replacement and maintenance.

[0063] Modular design allows users to arbitrarily combine and arrange different types of contacts, including power contacts, signal contacts, and fiber optic interfaces, according to specific signal transmission requirements.

[0064] Optionally, such as Figure 1 Combination Figure 5 As shown, the socket in this application also includes a mounting plate 8 and an end cover 9; the mounting plate 8 is used to fix the main housing 1 and the end cover 9, and the end cover 9 is sealed on the end of the main housing 1 away from the first port 101 and the second port 102.

[0065] The mounting plate 8 provided in this application can be made of high-strength stainless steel and precision stamped, possessing sufficient rigidity and durability. The mounting plate 8 is connected to the vehicle end structure via anti-loosening bolts, ensuring stability under vibration.

[0066] The end cap 9 is made of aluminum alloy and is detachably connected to the main housing 1 by bolts. A sealing ring is also provided between the end cap 9 and the main housing 1 to achieve a sealed connection between the end cap 9 and the main housing 1. In this application, the end cap 9 is placed on the rear end of the main housing 1, which facilitates the introduction of cables and provides necessary protection.

[0067] Preferably, the main housing 1, the secondary housing 2, and the outer shell 301 in this application are all coated with an insulating layer, thereby avoiding the problem of the housing being electrified and improving the safety of use.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
