Description

Technical Field

[0001] The utility model belongs to the technical field of shielded joint accessories, and in particular relates to a shielded connector. Background Art

[0002] Shielded connectors are classified into two types based on materials: metal type and metal-plastic hybrid type.

[0003] The functions of conventional shielded cable connectors include locking and fixing cables, waterproof sealing and shielding protection. The structure of conventional shielded cable connectors basically includes three categories, which are composed of the shell, seal and shielding parts of the shielded connector. The shell is mainly divided into two types, one is the connector body with mounting threads installed in the box hole or threaded position, and the other is a round nut, which is mainly responsible for connecting the connector body and pressing and squeezing the seal to achieve the effect of locking the cable and waterproofing; there are also two types of seals, one is the core body of the cable compressed and locked by the cap, and the other is the sealing O-ring between the connector body and the box body. The seal makes the cable and the entry hole completely sealed, so that the working space of the equipment can be isolated from the external environment to achieve waterproof and dustproof protection; the shielding part makes the cable shielding layer and the outer shell conductive, so that the electromagnetic field generated when the high voltage current passes through is completely shielded to prevent the strong electromagnetic field from damaging the internal components.

[0004] The existing ordinary shielded connectors have complex shielding mechanism design and often need to be disassembled for installation, and the production cost is high. The labor cost for installation is very high, and the user end often has to consider the complexity of installation and use, which increases training costs and fault tolerance costs; secondly, conventional connectors require locking round nuts to compress the sealing core to produce sealing performance, which requires manual locking of the cable connector, and for some locations with complex environments and narrow spaces, installation and locking are very inconvenient; finally, due to fierce competition in the industry, the demand for cost is becoming increasingly fierce, and lower-cost connectors are needed. Utility Model Content

[0005] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide a shielded connector.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] The shielded connector comprises a metal shell, the metal shell is integrally connected with a tightening cylinder and a pressing cylinder, a sealing colloid is placed inside the metal shell, a plurality of slots are evenly arranged inside the tightening cylinder, a triangular spring is placed in the slot, a hard cylinder is placed in the pressing cylinder, and a soft colloid is connected to the bottom of the hard cylinder;

[0008] The outer side of the tightening cylinder is provided with a first external thread, the outer side of the pressing cylinder is provided with a second external thread, the second external thread is threadedly connected with a hexagonal nut, and the hexagonal nut is integrally connected with a retaining edge with a specification and size adapted to the hard cylinder;

[0009] A sealing groove is provided at the corner where the tightening cylinder and the metal shell are connected, and a sealing ring is placed in the sealing groove.

[0010] It is further defined that convex rings are provided on both sides of the sealing gel inside and outside. Such a design enlarges the contact point between the inner diameter and the outer diameter, and the internal convex ring can prevent the cable from contacting the metal shell after being covered and positioned.

[0011] It is further defined that a hexahedron having the same specifications as the hexagonal nut is integrally provided on the outer side of the metal shell. With such a design, both can be rotated using a wrench of the same specifications.

[0012] It is further defined that the maximum outer diameters of the tightening cylinder and the pressing cylinder are different. Such a design can flexibly select different installation methods according to the different diameters of the threaded holes at the installation position, that is, using the tightening cylinder as the tightening end or choosing to use the pressing cylinder as the tightening end.

[0013] It is further defined that the inner ring of the retaining edge is installed with insulating soft rubber. Such a design not only has an insulating effect, but also prevents the cable from contacting with the hard retaining edge and being worn.

[0014] The beneficial effects of adopting the utility model are:

[0015] The structural design of the utility model has a compact overall structure, a reduced number of parts, and a significant reduction in the cost of mass-produced products. It also has the advantages of quick installation, reduced cost, and reduced weight.

[0016] By adopting the structural design of the utility model, the cable sealing colloid can protect the cable, so that the cable will not be worn due to contact with the hard metal shell;

[0017] With the structural design of the utility model, rotating the hexagonal nut can achieve resistance to the hard cylinder, thereby causing the hard cylinder to resist the soft colloid, and then causing the soft colloid to press the outside of the cable, thereby achieving a fixing effect on the cable and achieving the purpose of resisting pulling.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 , Figure 2 As shown, the shielded connector of the utility model comprises a metal shell 1, the metal shell 1 is integrally connected with a tightening cylinder 2 and a pressing cylinder 3, a sealing colloid 4 is placed inside the metal shell 1, a plurality of card grooves 5 are evenly arranged in the tightening cylinder 2, a triangular spring 6 is placed in the card groove 5, a hard cylinder 7 is placed in the pressing cylinder 3, and a soft colloid 8 is connected to the bottom of the hard cylinder 7;

[0025] A first external thread 9 is provided on the outside of the tightening cylinder 2, a second external thread 10 is provided on the outside of the pressing cylinder 3, the second external thread 10 is threadedly connected with a hexagonal nut 11, and the hexagonal nut 11 is integrally connected with a retaining edge 12 whose specifications and dimensions are adapted to the hard cylinder 7;

[0026] A sealing groove 13 is provided at the corner where the tightening cylinder 2 and the metal shell 1 are connected, and a sealing ring 14 is placed in the sealing groove 13 .

[0027] In this embodiment, when the shielded connector is used, the wire sealing colloid 4 is forcibly inserted into the metal shell 1. Since the wire sealing colloid 4 is a soft part, it is possible to insert it into the metal shell 1. Then the triangular spring 6 is inserted into the card slot 5. The card slot 5 can limit the direction of the triangular spring 6 to ensure that the direction of the triangular spring 6 correctly contacts the shielding layer of the cable. Then, the hard cylinder 7 is placed into the pressing cylinder 3 with the soft colloid 8 facing the direction of the metal shell 1. The metal shell 1 is screwed into the installation position of the chassis by screwing the tightening cylinder 2 to complete the preparation work.

[0028] Insert the cable directly into the sealing gel 4, so that the cable shielding layer is in close contact with the triangular spring 6, the triangular spring 6 is in close contact with the metal shell 1, and the metal shell 1 is in contact with the chassis thread to achieve conductive grounding shielding. After the cable passes through the sealing gel 4, the sealing gel 4 is deformed and pressed tightly against the outer skin of the customer's cable and the inner wall of the metal shell 1, so that the entire shielded connector, the cable and the metal shell 1 maintain good sealing performance. Then rotate the hexagonal nut 11 to move the hexagonal nut 11 toward the direction of the metal shell 1, so that the retaining edge 12 presses against the hard cylinder 7. Under this pressing force, the soft gel 8 is deformed and presses the cable tightly, so as to fix the cable position and resist pulling.

[0029] Preferably, both inner and outer sides of the sealing rubber 4 are provided with convex rings 15. Such a design enlarges the contact points between the inner diameter and the outer diameter. The internal convex ring 15 can prevent the cable from contacting the metal shell 1 after being covered and positioned. In fact, the specification and size of the convex ring 15 can also be considered according to specific circumstances.

[0030] Preferably, a hexahedron having the same specifications as the hexagonal nut 11 is integrally provided on the outer side of the metal shell 1. With this design, both can be rotated using a wrench of the same specifications. In fact, a structure that facilitates rotation can also be considered according to specific circumstances.

[0031] Preferably, the maximum outer diameters of the tightening cylinder 2 and the pressing cylinder 3 are different. Such a design can flexibly select different installation methods according to the different diameters of the threaded holes at the installation position, that is, using the tightening cylinder 2 as the tightening end or choosing to use the pressing cylinder 3 as the tightening end. In fact, the maximum outer diameters of the tightening cylinder 2 and the pressing cylinder 3 can also be considered according to the specific situation.

[0032] Preferably, the inner ring of the retaining edge 12 is installed with an insulating soft rubber 16. Such a design not only has an insulating effect, but also prevents the cable from contacting and wearing the hard retaining edge 12. In fact, protective measures can also be considered according to specific circumstances.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
