Description

Technical Field

[0001] This utility model relates to the field of automotive connector technology, and in particular to a structure for an automotive shielded wire connector. Background Technology

[0002] The use of new energy vehicles, especially electric vehicles, is becoming increasingly widespread. Electric vehicles use more and more types of wires, which in turn requires more wire connectors. The existing wire connectors have diverse structures, and many also have shielding functions to ensure stable current transmission and secure signal data transmission.

[0003] There are also many existing connector patent technologies. For example, Chinese patent application number 201721149280.8 discloses a fully shielded connector and a fully shielded connection structure for new energy vehicles, belonging to the field of anti-interference structures for vehicle-mounted connectors in new energy vehicles. It includes a socket and a mating plug. The socket has a socket housing capable of shielding interference signals, and the socket housing is connected to and electrically conductive with a corresponding first shielding structure for shielding interference signals. The plug has a plug housing capable of shielding interference signals, and the socket housing is connected to and electrically conductive with a corresponding second shielding structure for shielding interference signals. Elastic shielding elements capable of shielding interference signals are respectively provided at the connection points between the plug housing and the second shielding structure, the connection points between the socket housing and the first shielding structure, and the mating points between the socket housing and the plug housing.

[0004] The existing connectors have good shielding effect, but the use of so many wires and connectors will reduce safety. For example, the shielding effect needs to be improved, and the connectors themselves may overheat and cause fires in severe cases. Utility Model Content

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0028] Examples, such as Figure 1-9 As shown, a vehicle-mounted shielded wire connector structure includes an inner shielding surround 1 for wrapping the conductor core end of the shielded wire. Of course, shielded wires include many types of wires, such as audio cables, video cables, and signal cables. The main body, in addition to the conductor core, also has a shielding layer and an insulating layer wrapped around the conductor core. However, during assembly with the connector, the outer layer structure is peeled off at the end, leaving the conductor core. Because the end will be assembled with the connector, the conductor core end will be exposed at the end of the shielded wire and assembled with the connector. In this example, the inner shielding surround 1 is the first layer of shielding protection for the connector. Further, the inner... The inner shielding buckle 1 is equipped with a Hall sensor 2 for current detection. The Hall sensor 2 can be an existing millimeter-level miniature Hall current sensor, which can detect the current of the conductor core, thereby monitoring the current in real time. When an abnormality occurs, it can notify the system and issue an alarm, making it safer and more reliable. Of course, the Hall sensor 2 is located in the inner part of the inner shielding buckle 1, which does not affect its use. Furthermore, the inner shielding buckle 1 is covered by an outer shielding cover 3, which further strengthens the shielding protection and is also structurally reinforced, providing better protection.

[0029] Furthermore, the outer shielding enclosure 3 is installed in the outer protective housing 4, which is generally made of injection molded parts for better protection on the outside.

[0030] Preferably, the inner shielding enclosure 1 is provided with a reinforcing iron core 5 for surrounding the conductor core end of the shielding wire. Since the current flowing through many wires is relatively weak, the iron core can not only reduce the interference of the external magnetic field and effectively concentrate the current magnetic field on the conductor core, but also ensure the effectiveness of Hall detection, further improve the accuracy of the detection data and grasp the overall current situation, better report to the system, and obtain effective control. When an accident occurs, it can be detected and dealt with in a timely manner.

[0031] Furthermore, the reinforcing core 5 is C-shaped with the opening facing upwards. The Hall sensor 2 is mounted on the left and right sides of the upper opening of the reinforcing core 5. This structural design is suitable for the installation of the Hall sensor 2.

[0032] The upper opening of the reinforcing core 5 has stepped grooves 20 on both sides for the Hall sensor 2 to be positioned downwards. The Hall detection part 21 of the Hall sensor 2 is located in the upper opening of the reinforcing core 5 and below the Hall sensor 2. The Hall detection part 21 is the part used for detection. Being in the upper opening of the reinforcing core 5, it is closer to the conductor core and can detect more accurately. The Hall sensor 2 is further fixed in the stepped groove 20 by existing fixing methods such as screws.

[0033] Preferably, the inner shielding buckle 1 includes a cylindrical inner shielding sleeve 11. An elastic extrusion piece 111 for extruding the conductor core end of the shielding wire is integrally connected inside the inner shielding buckle 1. The inner shielding buckle 1 is made of copper or aluminum. The elastic extrusion piece 111 is integrally connected to the inner wall of the inner shielding sleeve 11 and is distributed in a circumferential array. The elastic extrusion piece 111 can preferably be in an oblique shape that is inclined towards the axis and backward, or it can preferably be in an arc-shaped arch shape towards the axis. The main purpose is to abut the conductor core end. The elastic structure also facilitates axial insertion. In this embodiment, the shielding wire is inserted backward and a terminal is connected to the rear side.

[0034] Preferably, the inner shielding sleeve 11 is integrally connected with a front limiting piece 112 and a rear limiting piece 113, which are spaced apart and used to limit the front and rear of the reinforcing core 5. The front limiting piece 112 and the rear limiting piece 113 can be arc-shaped and can be C-shaped with the opening facing upwards. Since it is designed internally, the reinforcing core 5 can be encapsulated together during the integral molding process. An opening can be made on the part of the inner shielding sleeve 11 where the reinforcing core 5 is located to facilitate the insertion of the reinforcing core 5. Of course, after insertion, the reinforcing core 5 can be fixed between the front limiting piece 112 and the rear limiting piece 113 by existing installation methods such as pins.

[0035] Furthermore, the inner wall of the inner shielding sleeve 11 is integrally connected with an inner wire guide tube 114 for guiding the connection wire of the Hall sensor 2 and extending axially. The inner wire guide tube 114 is located in the upper part of the inner shielding sleeve 11. Since the Hall sensor 2 is wired, its connection wire needs to be led out. In this way, it is led out together with the conductor core end of the shielding wire to the front side and connected to the terminal block.

[0036] Preferably, the outer shielding cover 3 includes a cylindrical outer shielding sleeve 31 that covers the inner shielding sleeve 11, and a tightening sleeve 32 integrally connected to the front side of the outer shielding sleeve 31 for covering the shielding wire. The diameter of the outer shielding sleeve 31 is larger than the diameter of the tightening sleeve 32. It can be understood that the outer shielding cover 3 is a single bushing structure with a smaller diameter at the front and a larger diameter at the rear. This diameter includes both the inner and outer diameters. That is, the tightening sleeve 32 is also cylindrical, and both its inner and outer diameters are smaller than those of the outer shielding sleeve 31. The tightening sleeve 32 presses firmly against the outer side of the complete shielding wire. The outer shielding cover 3 is preferably composed of two halves, which can be joined by a clamping clamp, or the two halves can preferably have a snap-fit ​​structure for interlocking. The outer shielding cover 3 can be made of the same material as the inner shielding cover buckle 1.

[0037] Preferably, the structure of the outer protective housing 4 needs to be adapted to the outer protective housing 3. The outer protective housing 4 forms an embedding groove 40 for the outer shielding cover 3 to be inserted. The shape of the embedding groove 40 matches the outer shielding sleeve 31 and the tightening sleeve 32. The embedding groove 40 has two continuous cylindrical grooves. The outer protective housing 4 is also provided with a terminal insertion groove 41 for inserting wiring terminals. A wiring terminal 42 can be configured for the connecting wire of the Hall sensor 2 and the conductor core of the shielding wire respectively. The connecting wire of the Hall sensor 2 is relatively thin and can be equipped with a wiring terminal of a certain size, while the conductor core is equipped with a larger wiring terminal. The two can be electrically connected to the wiring terminals by welding or other existing electrical connection methods. The outer protective housing 4 is made of injection molding as mentioned above, and preferably has a structure of upper and lower halves spliced ​​together. The edges of the upper and lower halves can be integrally formed into upper and lower snap-fit ​​structures or pin-hole plug-in structures, similar to existing upper and lower splicing structures. Of course, it can also be spliced ​​by drilling holes and locking with screws, which is convenient for installation.

[0038] Through the above design, on the one hand, the shielding effect is better, and on the other hand, the current can be better detected, thus providing better safety assurance.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
