Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-interference connector technology, and in particular to a stable and reliable anti-interference connector. Background Technology
[0002] Interference-resistant connectors are connectors specifically designed to maintain stable signal transmission in environments with electromagnetic interference (EMI) and radio frequency interference (RFI). They are widely used in aerospace, military, communications, medical equipment, and other fields with extremely high signal integrity requirements.
[0003] In base stations, routers, and other communication equipment, anti-interference connectors can improve signal quality and transmission distance. In industrial control systems, anti-interference connectors can prevent electromagnetic interference from affecting the system. For example, the prior art, Chinese Patent Publication No. "CN219576113U", provides a stable and reliable anti-interference connector, including crystal heads at both ends and a cable for connecting the crystal heads at both ends. The cable is equipped with an anti-interference ferrite ring. This utility model achieves the effect of strengthening the anti-interference capability of the cable by adding an anti-interference ferrite ring to the outside of the cable. Moreover, this method of installation can be applied only to designated areas according to actual conditions, so it can maximize cost savings. It is also convenient to use and the anti-interference ferrite ring can be kept as a spare, making it highly practical.
[0004] Currently, most anti-interference connectors rely solely on the insertion structure at the connector position for fixation when connecting adjacent components. In actual use, if pulling occurs, they are very easy to detach, resulting in low stability. Furthermore, when adjacent connector interfaces are mated, there is no good protection against external electromagnetic interference or waterproofing at the connection point, which greatly reduces the reliability and stability of adjacent connectors during mating. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a stable and reliable anti-interference connector.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a stable and reliable anti-interference connector, including a protective cover one and a protective cover two. The open end of the protective cover one is closed with the open end of the protective cover two. A connector one is provided inside the protective cover one, and a power transmission line one is provided at the tail of the connector one. A connector two is provided inside the protective cover two, and a power transmission line two is provided at the tail of the connector two.
[0008] A sealing sleeve is provided inside the protective cover. The inner side of the sealing sleeve is fitted and attached to the outer wall of the transmission line. An adhesive layer is embedded in the inner ring wall of the sealing sleeve. The adhesive layer is bonded and fixed to the sealing sleeve and the transmission line respectively.
[0009] The protective cover 2 has a sealing sleeve 2 inside, and the inner side of the sealing sleeve 2 is fitted and attached to the outer wall of the transmission line 2. The inner ring wall of the sealing sleeve 2 has an adhesive layer 2 embedded in it, and the adhesive layer 2 is bonded and fixed to the sealing sleeve 2 and the transmission line 2 respectively. The adhesive layer 1 and adhesive layer 2 are epoxy resin adhesive.
[0010] In detail, the end face of the first protective cover is provided with an internal groove, which is a ring structure, and the end of the second protective cover slides into and connects with the inside of the internal groove.
[0011] In detail, a threaded sleeve is fixed on the outer wall of the first protective cover. There are at least two threaded sleeves, which are equidistantly distributed in a ring along the surface of the first protective cover. A threaded sleeve is fixed on the outer wall of the second protective cover. The position of the threaded sleeve corresponds one-to-one with the position of the threaded sleeve.
[0012] In detail, the same threaded pin is provided through the interior of both the threaded sleeve one and the threaded sleeve two, and the outer threaded surface of the threaded pin is threadedly connected to the inner threaded surface of the threaded sleeve one and the threaded sleeve two, respectively.
[0013] In detail, the first protective cover sequentially includes a wear-resistant layer, a shielding layer, and an insulating layer. The shielding layer is fixedly wrapped inside the wear-resistant layer, and the insulating layer is fixedly wrapped inside the shielding layer. The structural composition of the first protective cover is the same as that of the second protective cover.
[0014] In detail, the wear-resistant layer is made of high-strength polyvinyl chloride material.
[0015] In detail, the shielding layer is made of a soft magnetic material.
[0016] In detail, the insulating layer is made of a hard rubber material.
[0017] The design scheme proposed in this utility model has the following beneficial effects in application:
[0018] 1. When adjacent connectors are mated through the joint, the protective cover one can be installed with the joint one and the protective cover two can be installed with the joint two respectively, which can achieve the wrapping and covering of the joint position. The adhesive layer one can be used to stably install the protective cover one with the joint one, and the adhesive layer two can be used to stably install the protective cover two with the joint two. The adhesive layers at the two positions can not only bond the components, but also play a waterproof and sealing role.
[0019] 2. During the installation of protective cover one and protective cover two, the basic connection can be achieved by inserting protective cover two into the built-in groove at the port of protective cover one. Simultaneously, the installation and fixation of protective cover one and protective cover two can be achieved by threaded pins passing through and threaded onto threaded sleeve one and threaded sleeve two respectively.
[0020] 3. In normal use, the protective cover one and the protective cover two have the same structure. The wear-resistant layer made of high-strength polyvinyl chloride material can provide external waterproof, corrosion-resistant and wear-resistant effect. The shielding layer made of soft magnetic material can provide external electromagnetic wave interference resistance. The insulating layer made of hard rubber material can provide insulation protection for internal connectors during docking. Attached Figure Description

[0028] 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.
[0029] Reference Figures 1-6A stable and reliable anti-interference connector includes a protective cover 1 and a protective cover 2 11. The open end of the protective cover 1 is closed with the open end of the protective cover 2 11. A connector 12 is provided inside the protective cover 1, and a power transmission line 13 is provided at the tail of the connector 12. A connector 2 14 is provided inside the protective cover 2 11, and a power transmission line 2 15 is provided at the tail of the connector 2 14.
[0030] A sealing sleeve 16 is provided through the interior of the protective cover 1. The inner side of the sealing sleeve 16 is fitted and attached to the outer wall of the transmission line 13. An adhesive layer 17 is embedded in the inner ring wall of the sealing sleeve 16. The adhesive layer 17 is bonded and fixed to the sealing sleeve 16 and the transmission line 13 respectively.
[0031] The protective cover 211 has a sealing sleeve 218 that runs through it. The inner side of the sealing sleeve 218 is fitted and attached to the outer wall of the transmission line 215. The inner ring wall of the sealing sleeve 218 has an adhesive layer 219 embedded in it. The adhesive layer 219 is bonded and fixed to the sealing sleeve 218 and the transmission line 215 respectively. The adhesive layer 17 and the adhesive layer 219 are epoxy resin adhesive.
[0032] It should be further noted that the end face of the protective cover 1 is provided with an internal groove 2, which is a ring structure. The end of the protective cover 2 11 slides into and connects with the inside of the internal groove 2, which facilitates the further connection between the protective cover 1 and the protective cover 2 11 and can improve the sealing effect at the joint.
[0033] It should be further explained that a threaded sleeve 21 is fixed on the outer wall of the protective cover 1. There are at least two threaded sleeves 21, which are equidistantly distributed in a ring along the surface of the protective cover 1. A threaded sleeve 22 is fixed on the outer wall of the protective cover 21. The position of the threaded sleeve 22 corresponds one-to-one with the position of the threaded sleeve 21. By setting at least two sets of threaded sleeves 21 and threaded sleeves 22, the point distribution when the protective cover 1 and the protective cover 21 are connected can be kept stable.
[0034] It should be further noted that the same threaded pin 23 is provided inside both threaded sleeve 1 21 and threaded sleeve 22. The external threaded surface of the threaded pin 23 is threadedly connected to the internal threaded surface of threaded sleeve 1 21 and threaded sleeve 22 respectively. The threaded connection of the threaded pin 23 can make it cooperate with threaded sleeve 1 21 and threaded sleeve 22, thereby ensuring the stable installation of protective cover 1 and protective cover 2 11.
[0035] It should be further noted that the protective cover 1 comprises a wear-resistant layer 1001, a shielding layer 1002, and an insulating layer 1003 in sequence. The shielding layer 1002 is fixedly wrapped inside the wear-resistant layer 1001, and the insulating layer 1003 is fixedly wrapped inside the shielding layer 1002. The structural composition of the protective cover 1 is the same as that of the protective cover 2 11.
[0036] It should be further noted that the wear-resistant layer 1001 is made of high-strength polyvinyl chloride material, which can serve as an outer insulating protective structure, and at the same time, it can be wear-resistant, corrosion-resistant and waterproof, effectively improving the durability of the protective cover structure.
[0037] It should be further noted that the shielding layer 1002 is made of soft magnetic material. The soft magnetic material is filled between the wear-resistant layer 1001 and the insulating layer 1003, which can play a role in resisting interference from external electromagnetic waves, thereby improving the signal transmission stability of the connector.
[0038] It should be further noted that the insulating layer 1003 is made of hard rubber material. Through the hard rubber structure, the connection between the two connector joints can be insulated from the inside.
[0039] Working method: When adjacent connectors are mated through the joint, they can be installed by protective cover 1 and joint 12 respectively, and protective cover 2 11 and joint 2 14 respectively, which can cover the joint position. The adhesive layer 17 can be used to stably install protective cover 1 and joint 12, and the adhesive layer 2 19 can be used to stably install protective cover 2 11 and joint 2 14. The adhesive layers at the two positions can not only bond the components, but also play a waterproof sealing role.
[0040] During the installation of protective cover 1 and protective cover 2 11, the basic connection can be achieved by inserting protective cover 2 11 into the built-in groove 2 at the port position of protective cover 1. Simultaneously, the installation and fixation of protective cover 1 and protective cover 2 11 can be achieved by threaded pin 23 passing through and threadedly installed on threaded sleeve 1 21 and threaded sleeve 22 respectively.
[0041] In normal use, the protective cover 1 and the protective cover 2 11 have the same structure. The wear-resistant layer 1001 made of high-strength polyvinyl chloride material can provide external waterproof, corrosion-resistant and wear-resistant effect. The shielding layer 1002 made of soft magnetic material can provide external electromagnetic wave interference resistance. The insulating layer 1003 made of hard rubber material can provide insulation protection for internal connectors during docking.
[0042] 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.
