Description

Technical Field

[0001] The utility model relates to a waterproof and sealed radio frequency coaxial connector. Background Art

[0002] RF coaxial connectors are electrical connectors used to transmit radio frequency signals. They are widely used in radio communications, radar, satellite communications, cable TV, mobile communications, and other fields. These connectors are designed to ensure the integrity and minimal loss of RF signals during transmission while providing a stable connection.

[0003] In existing RF coaxial connector designs, the waterproof sealing performance of the connector is often overlooked, resulting in moisture easily invading the interior of the connector when used in humid environments, affecting the stability and reliability of signal transmission.

[0004] Traditional waterproof sealing measures usually use sealants or rubber gaskets, but these methods are prone to aging or failure during long-term or frequent underwater use and cannot provide effective waterproof protection. Therefore, a waterproof sealed RF coaxial connector is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a waterproof sealed radio frequency coaxial connector to solve the problem in the above background technology that traditional waterproof sealing measures cannot provide effective waterproof protection.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a waterproof and sealed radio frequency coaxial connector, comprising a radio frequency coaxial connector body, wherein connection grooves are provided on both sides of the connection end of the radio frequency coaxial connector body, and a clamping piece is provided at the connection groove.

[0007] The connection end of the radio frequency coaxial connector body is connected to a waterproof sealing member through a clamping member.

[0008] Preferably, the connection slot is in an "L" shape, and a gap is provided between the connection slot and the RF coaxial connector body.

[0009] Preferably, the clamping member includes a guide groove opened inside the connecting groove, the inside of the guide groove is slidably connected to a pressure plate, two sets of fixing rubber strips are provided at the tail end of the pressure plate, and the pressure plate and the connecting groove cooperate with each other to enable the pressure plate to move inside the connecting groove.

[0010] Preferably, multiple groups of return springs are arranged inside the connecting groove, and the return springs are located directly below the pressure plate.

[0011] Preferably, the waterproof seal comprises a waterproof cylinder, and a sealing strip is provided on the top surface of the waterproof cylinder;

[0012] The waterproof cylinder includes a top plate and a loading cylinder. The top plate is located on the upper portion of the loading cylinder. The interior of the loading cylinder is filled with a desiccant.

[0013] Preferably, a plurality of through holes are formed on the outer wall of the loading cylinder, and the diameter of the through holes is smaller than the diameter of the desiccant.

[0014] Preferably, the outer diameter of the waterproof cylinder is the same as the inner diameter of the connection end of the RF coaxial connector body, so that the waterproof cylinder can be loaded onto the connection end of the RF coaxial connector body.

[0015] Preferably, a clamping plate is provided on both sides of the loading cylinder, and the shape of the clamping plate is "L"-shaped. The connecting end and the gap between the clamping plate and the loading cylinder cooperate with each other, and the tail end of the clamping plate is the same as the width of the connecting groove, so that the tail end of the clamping plate is connected to the connecting groove and moves laterally in the gap through the connecting end.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model provides a structural waterproof measure by arranging connection grooves on both sides of the connection end of the connector body, arranging clamping pieces at the connection grooves, and connecting a waterproof sealing piece at the connection end through the clamping pieces, thereby effectively preventing moisture from intruding into the interior of the connector.

[0018] The "L"-shaped design of the connection groove and the gap between it and the connector body allow the waterproof tube to be quickly connected to the connection end of the RF coaxial connector body, improving the convenience of connection.

[0019] The pressure plate in the clamping fixture can move up and down inside the guide groove, and by squeezing the reset spring under the pressure plate, the compressive elastic force of the reset spring acts on the sealing strip, causing it to squeeze the sealing strip and produce elastic deformation, filling the gap at the connection of the RF coaxial connector body to improve the sealing effect.

[0020] The waterproof tube is filled with desiccant, which can absorb moisture that penetrates through the sealing strip, keep the inside of the connector dry, and thus protect signal transmission from being affected by moisture.

[0021] The through-hole design on the outer wall of the loading cylinder allows air to circulate and absorbs the intruding moisture. The size of the through-hole is smaller than that of the desiccant to ensure that the desiccant will not fall off.

[0022] The outer diameter of the waterproof cylinder is the same as the inner diameter of the connecting end of the connector body, ensuring that the waterproof cylinder can be tightly loaded onto the connector body and providing a good seal. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] To address the problem that traditional waterproof sealing measures cannot provide effective waterproof protection, the present invention provides a waterproof sealed RF coaxial connector. The following, in conjunction with the accompanying drawings, clearly and completely describes the technical solutions in the present invention. Obviously, the described embodiments are only a portion of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-4 The present invention provides a waterproof and sealed RF coaxial connector, comprising an RF coaxial connector body 1. Connecting grooves 101 are defined on both sides of the connecting end of the RF coaxial connector body 1. A clamping member 102 is disposed at the connecting groove 101. The clamping member 102 includes a guide groove 1021 defined within the connecting groove 101. A pressure plate 1022 is slidably connected to the guide groove 1021. Two sets of retaining rubber strips 1023 are disposed at the rear end of the pressure plate 1022. The pressure plate 1022 cooperates with the connecting groove 101 to enable the pressure plate 1022 to move within the connecting groove 101. Multiple sets of return springs 1024 are disposed within the connecting groove 101, and the return springs 1024 are located directly below the pressure plate 1022.

[0030] The waterproof seal 2 includes a waterproof cylinder 201, with a sealing strip 202 disposed on its top surface. The waterproof cylinder 201 includes a top plate 2011 and a loading cylinder 2012. The top plate 2011 is positioned above the loading cylinder 2012, which is filled with a desiccant. The outer wall of the loading cylinder 2012 is defined by a plurality of through-holes 2013, each smaller than the diameter of the desiccant. The outer diameter of the waterproof cylinder 201 is identical to the inner diameter of the connecting end of the RF coaxial connector body 1, enabling the waterproof cylinder 2011 to be loaded onto the connecting end of the RF coaxial connector body 1. Snap-on plates 2014 are provided on both sides of the loading cylinder 2012. The shape of the snap-on plates 2014 is "L"-shaped. The connecting ends between the snap-on plates 2014 and the loading cylinder 2012 cooperate with the gap 103. The tail end of the snap-on plate 2014 has the same width as the connecting groove 101, so that the tail end of the snap-on plate 2014 is connected to the connecting groove 101 and moves laterally in the gap 103 through the connecting end.

[0031] The connection end of the RF coaxial connector body 1 is connected to the waterproof seal 2 via a clamping member 102 .

[0032] The connection slot 101 is in an “L” shape, and a gap 103 is provided between the connection slot 101 and the RF coaxial connector body 1 .

[0033] The working principle of the waterproof and sealed radio frequency coaxial connector provided by the present invention is as follows: during installation, the clamping plates 2014 on both sides of the waterproof cylinder 201 are connected to the bottom along the connecting groove 101, and then the waterproof cylinder 201 is pressed downward, so that it squeezes the return spring 1024 through the pressure plate 1022. The return spring 1024 is forced to shrink until the clamping plates 2014 are clamped at the gap 103. The waterproof cylinder 201 is rotated through the gap 103 until the clamping plates 2014 rotate to the retaining rubber strip 1023 at the tail end of the pressure plate 1022. The elastic force generated by the shrinkage of the return spring 1024 acts in the opposite direction on the pressure plate 1022, causing the clamping plates 2014 to abut against the connecting groove 101, thereby fixing the waterproof cylinder 201.

[0034] The pressure plate 1022 moves upward to act on the sealing strip 202, causing the sealing strip 202 to generate compression deformation during the subsequent connection of the RF coaxial connector, thereby filling the connection gap of the RF coaxial connector and improving the sealing effect;

[0035] During daily use, external moisture penetrates into the RF coaxial connector through the gaps, enters the waterproof tube 201 along the through hole 2013, and is absorbed and dried by the desiccant, thus avoiding penetrating into the internal connection of the RF coaxial connector.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
