Description

Technical Field

[0001] The invention belongs to the technical field of coaxial connectors, and in particular relates to an anti-dropping SHV coaxial connector. Background Art

[0002] A coaxial connector refers to a part used to connect the ends of two shafts to ensure that the center lines of the two shafts are on the same axis. It generally refers to a connection component used to carry out connection and docking functions between two groups of circuits. The whole is composed of a plug-in end and a docking end. A card connector installed on the outside of the plug-in end is used to ensure the stability of the plug-in end and the docking end when docking, and to assist in the docking and connection of the connecting circuits on both sides. It is now commonly used as a connection component between high-voltage power supplies and devices in nuclear instruments or electronic measuring devices. Among them, SHV coaxial connectors are generally used in ultra-high-definition RF instruments to ensure the accuracy of information transmission.

[0003] Today's SHV coaxial connectors are classified into several types according to the connection method, including spiral type, snap-on type and sliding type. Among them, the snap-on connector is the most commonly used type for connecting high-voltage power supplies and devices. Generally, the coaxial connector is docked by snapping the card slot in the plug-in end with the card rod in the docking end. However, there are certain problems in actual use. Specifically, when the snap-on coaxial connector is in use, the card slot outside the plug-in end is directly exposed to the air. When the connector connection is squeezed, it is easy to cause the card rod to detach from the card slot, affecting the stability of the device docking, and external dust and impurities will enter the connector through the exposed card slot, affecting the stability of the connector conduction circuit.

[0009] As a preferred technical solution of the present invention, an extrusion arc block is installed on the inner wall of the external protective ring, and the shape of the extrusion arc block is consistent with the shape of the clamping groove. When the position of the extrusion arc block is aligned with the clamping groove, the external protective ring is pressed, and the moving guide frame slides in the slide groove, so that the extrusion arc block enters the clamping groove and drives the clamping rod to disengage from the clamping groove.

[0010] As a preferred technical solution of the present invention, it also includes a deflection mechanism, which includes a meshing gear, a worm and a worm wheel. A rotating groove is opened on the outer wall of the connector shell, and a meshing gear is rotatably installed in the rotating groove. The meshing gear is meshed with a rotating gear ring. A worm is installed on the meshing gear. The worm is rotatably installed in the connector shell, and a worm wheel is rotatably installed in the connector shell. The worm wheel is meshed with the worm, and a limiting mechanism is connected to the worm wheel. The rotation of the worm wheel drives the limiting mechanism to swing in the connector shell to limit the plug port.

[0011] As a preferred technical solution of the present invention, the limiting mechanism includes a linkage rod installed on the axis of the worm gear, and a swinging extrusion rod is installed outside the linkage rod. The swinging extrusion rod swings in the connector housing due to the rotation of the worm gear and presses against the plug-in port to limit the plug-in port.

[0012] As a preferred technical solution of the present invention, the swing extrusion rod is composed of a side baffle and a pressing round rod. The side baffle is installed at the end of the linkage rod, and the pressing round rod is installed on the side of the side baffle.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] Firstly, the connector in the present invention is provided with a protective mechanism and a clamping rod. When the plug-in port is docked with the connector shell, the clamping rod cooperates with the clamping groove to achieve preliminary docking of the plug-in port and the connector shell. The external protective ring protects and shields the entire connector shell to prevent dust from entering the connector shell through the clamping groove. In addition, the external protective ring rotates to change the position of the extrusion arc block, so that the extrusion arc block is misaligned with the clamping groove, thereby preventing the external protective ring from causing the extrusion arc block to enter the clamping groove due to collision, causing the plug-in port and the connector shell to fall off.

[0018] Secondly, the connector in the present invention is also provided with a deflection mechanism. When the plug-in port is connected to the connector housing, the external protective ring is rotated, and the cooperation and conduction of the worm gear and the worm are utilized to make the two sets of swing rods deflect to one side of the docking tube at the same time, thereby limiting the plug-in port, ensuring the stability between the plug-in port and the connector housing, assisting the stable transmission of the circuits of the two, and enhancing the stability of the docking between the two.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, it is a schematic diagram of the structure of the SHV coaxial connector in this embodiment, the SHV coaxial connector includes a plug-in port 1 and a connector shell 2 docked with the plug-in port 1, a shielding crimping ring 3 is installed at the end of the connector shell 2, an outer bearing ring 4 is fixedly installed on the outside of the connector shell 2, a clamping rod 5 is installed on the plug-in port 1, and two groups of clamping rods 5 are provided. A clamping groove 11 for clamping with the clamping rod 5 is opened on the connector shell 2, and a protective mechanism 6 for closing and shielding the clamping groove 11 is provided on the outside of the connector shell 2.

[0035] During use, the connector shell 2 is docked with the plug-in port 1. At this time, the clamping rod 5 on the plug-in port 1 will shrink due to the squeezing of the inner wall of the connector shell 2, assisting the connector shell 2 to be plugged with the plug-in port 1. When the connector shell 2 is plugged with the plug-in port 1, the clamping rod 5 pops up as a whole and enters the clamping groove 11 to avoid the problem of the connector shell 2 and the plug-in port 1 falling off.

[0036] By the attached Figure 4 and Figure 5As shown, it is a schematic diagram of the structure of the protection mechanism 6 in this embodiment, the protection mechanism 6 includes an external protection ring 61, an extruded arc block 62, a movable guide frame 63, a first spring 64 and a bent plastic sheet 65, the external protection ring 61 is arranged outside the connector housing 2, and there are two groups of external protection rings 61, and the two groups of external protection rings 61 are surrounded on the outside of the connector housing 2 to protect the connector housing 2. In this embodiment, an extruded arc block 62 is arranged on the inner wall of the external protection ring 61, and in the initial state, the extruded arc block 62 is aligned with the clamping groove 11, and the two groups of external protection rings 61 are aligned with each other. A bent plastic sheet 65 is connected in between, and two sets of external protective rings 61 and the bent plastic sheet 65 are enclosed on the outside of the connector housing 2 to prevent dust from entering the inside of the connector housing 2. The movable guide frame 63 is installed at the end of the external protective ring 61 and a first spring 64 is installed on the movable guide frame 63. After the plug-in port 1 is plugged into the connector housing 2, the clamping rod 5 enters the clamping groove 11. When the SHV coaxial connector in this embodiment needs to be disassembled, the external protective ring 61 is pressed to squeeze the arc block 62 into the clamping groove 11, thereby driving the clamping rod 5 to disengage from the clamping groove 11, so as to facilitate the plug-in port 1 to disengage from the connector housing 2.

[0037] In order to prevent the external protective ring 61 from being collided and causing the extruded arc block 62 to enter the clamping groove 11, thereby causing the clamping rod 5 to be detached from the clamping groove 11, in this embodiment, after the plug port 1 and the connector housing 2 are docked, the two sets of external protective rings 61 are rotated to make the extruded arc block 62 and the clamping groove 11 misaligned. Even if the external protective ring 61 is collided or shaken during use, the external protective ring 61 will withstand a large amount of impact, preventing the clamping rod 5 from shrinking and detaching from the inside of the clamping groove 11 due to external impact.

[0038] When the plug-in port 1 and the connector shell 2 need to be separated, the outer protective ring 61 is rotated to align the extruded arc block 62 on the inner wall of the outer protective ring 61 with the snap-in groove 11, and then the two sets of outer protective rings 61 are pressed at the same time to allow the extruded arc block 62 to enter the snap-in groove 11, and the snap-in rod 5 protruding from the inside of the snap-in groove 11 is pressed to drive the overall position of the snap-in rod 5 to shrink, thereby releasing the snap-in connection between the connector shell 2 and the plug-in port 1, and facilitating the plug-in port 1 to be pulled out from the inside of the connector shell 2. At the same time, the bent plastic sheet 65 is deformed in coordination with the movement of the outer protective ring 61 to facilitate the extruded arc block 62 to enter the snap-in groove 11. In addition, the outer protective ring 61 and the bent plastic sheet 65 in this embodiment jointly protect the connector shell 2 to prevent dust from entering the inside of the connector shell 2.

[0039] By the attached Figure 6 And attached Fig. 9As shown, a central conductor 9 for docking with the plug port 1 is installed inside the connector housing 2 , and a polyetheretherketone structural component 10 is installed inside the connector housing 2 . The polyetheretherketone structural component 10 is fixedly connected to the central conductor 9 .

[0040] In the present embodiment, the center conductor 9 is inserted into the polyetheretherketone structural part 10, and the two are interference fit to ensure the stability of the center conductor 9 when docking with the polyetheretherketone structural part 10. When the center conductor 9 is docked with the plug-in port 1, the polyetheretherketone structural part 10 can provide stable support for the center conductor 9 to prevent the center conductor 9 from loosening or misalignment after being plugged into the plug-in port 1 for many times. In the present embodiment, the polyetheretherketone structural part 10 is made of polyetheretherketone material, which has the advantages of good corrosion resistance, aging resistance, high temperature and high pressure, wear resistance, and anti-static. After the center conductor 9 is docked and operated with the plug-in port 1 for a long time, the overall temperature of the center conductor 9 rises. The polyetheretherketone structural part 10 can support the center conductor 9 while bearing the high temperature and high pressure of the center conductor 9, thereby ensuring the stability of the center conductor 9.

[0041] By the attached Figure 6 , Figure 7 and Figure 8 As shown, the SHV coaxial connector in this embodiment also includes a deflection mechanism 7, which includes a rotating gear ring 71, a meshing gear 72, a rotating groove 73, a worm 74 and a worm wheel 75. In this embodiment, a rotating groove 73 is provided on the surface of the connector housing 2, and a meshing gear 72 is rotatably installed inside the rotating groove 73. A rotating gear ring 71 is rotatably installed on the outer bearing ring 4, and the rotating gear ring 71 is meshed with the meshing gear 72. By rotating the rotating gear ring 71, the meshing gear 72 can be driven to rotate in the rotating groove 73. Figure 8 As shown, a worm 74 is installed on the meshing gear 72, and the worm 74 is rotatably installed inside the connector housing 2. In this embodiment, a worm wheel 75 is also installed in the connector housing 2, and the worm wheel 75 meshes with the worm 74. When the rotating gear ring 71 rotates, the meshing gear 72 can be driven to rotate, thereby driving the worm 74 to rotate and driving the worm wheel 75 to rotate. In this embodiment, a linkage rod is installed on the axis of the worm wheel 75, and a swing extrusion rod 8 is installed on the outside of the linkage rod. When the worm wheel 75 rotates, the swing extrusion rod 8 is driven to swing inside the connector housing 2 through the linkage rod.

[0042] like Figure 6As shown, in this embodiment, a slide groove 76 is provided on the side wall of the rotating gear ring 71, and the movable guide frame 63 at the end of the external protective ring 61 is slidably installed in the slide groove 76, and a first spring 64 is installed between the movable guide frame 63 and the slide groove 76. When the external protective ring 61 is pressed and moved, the first spring 64 is compressed and stored. After the force applied by the external protective ring 61 is released, the first spring 64 is reset; in addition, when the external protective ring 61 rotates to drive the extrusion arc block 62 to be misaligned with the clamping groove 11, the external protective ring 61 drives the rotating gear ring 71 to rotate, and then drives the swing extrusion rod 8 to swing in the connector housing 2 through the deflection mechanism 7. Specifically, the rotation of the external protective ring 61 When the outer protective ring 61 is in the state of being rotated, the movable guide frame 63 installed at the end of the outer protective ring 61 will drive the rotating gear ring 71 to rotate synchronously, and the rotating gear ring 71 will mesh with the two sets of meshing gears 72. The meshing gears 72 drive the worm 74 to rotate, and the worm 74 and the worm wheel 75 are meshed. The angle and position of the swinging extrusion rod 8 are adjusted in cooperation with the linkage rod, and the two sets of swinging extrusion rods 8 are driven to deflect to the side close to the center conductor 9 at the same time, so that the swinging extrusion rod 8 is squeezed against the side of the plug port 1, thereby ensuring the stability of the docking between the plug port 1 and the connector housing 2. When in use, the irreversible characteristics of the meshing between the worm 74 and the worm wheel 75 are utilized to ensure the stability of the docking between the plug port 1 and the connector housing 2.

[0043] When the plug-in port 1 and the connector housing 2 need to be separated, the outer protective ring 61 is rotated to align the extrusion arc block 62 with the snap-in groove 11. At the same time, the rotating gear ring 71 is rotated in the opposite direction, thereby driving the swing extrusion rod 8 to swing in the opposite direction through the deflection mechanism 7, thereby avoiding the swing extrusion rod 8 from pressing against the side wall of the plug-in port 1, thereby facilitating the separation of the plug-in port 1 and the connector housing 2.

[0044] By the attached Fig. 9 and Fig.10 As shown, the swing extrusion rod 8 is composed of a side baffle and a pressing round rod, the side baffle is installed on the end of the linkage rod, and the pressing round rod is installed on the side baffle. A docking sleeve 12 for docking with the center conductor 9 is installed on the side of the plug port 1, and a matching groove 13 for matching with the pressing round rod is opened on the side wall of the docking sleeve 12.

[0045] When the swinging extrusion rod 8 swings during use, it drives the pressing rod on the side baffle plate to enter the matching groove 13 in the plug-in port 1. The plug-in port 1 and the connector housing 2 are limited by the combined action of the matching groove 13 and the pressing rod, thereby avoiding the plug-in port 1 and the connector housing 2 from being separated.

[0046] The swinging extrusion rod 8 in this embodiment swings inside the connector housing 2 to facilitate the extrusion and limiting of the plug-in port 1. It is worth noting that the swinging extrusion rod 8 in this embodiment includes but is not limited to the structure of the side baffle and the pressing round rod, and any limiting mechanism that can swing inside the connector housing 2 to limit the plug-in port 1 is acceptable.

[0047] By the attached Fig.10 As shown, it is a structural schematic diagram of the clamping rod 5 in this embodiment, a contraction groove 51 is opened on the side wall of the plug-in port 1, the clamping rod 5 includes a movable clamping rod 52 and a second spring 53, and there are two groups of contraction grooves 51. The movable clamping rod 52 is slidably installed in the contraction groove 51, and the output end of the movable clamping rod 52 passes through the side wall of the plug-in port 1, and the second spring 53 is installed at the bottom end of the movable clamping rod 52, and the end of the second spring 53 is connected to the inner wall of the contraction groove 51. When the movable clamping rod 52 contracts into the contraction groove 51, the second spring 53 is in a force storage state.

[0048] During use, when the plug-in port 1 is docked with the connector shell 2, the connector shell 2 is plugged into the outside of the plug-in port 1. At this time, the movable card rod 52 is contracted into the contraction groove 51 due to the squeezing of the inner wall of the connector shell 2, and the second spring 53 enters the accumulation state. After the clamping rod 5 enters the clamping groove 11, the movable card rod 52 pops out under the elastic force of the second spring 53, driving the movable card rod 52 to clamp with the clamping groove 11, completing the preliminary positioning of the plug-in port 1 and the connector shell 2. It is worth noting that the clamping groove 11 in this embodiment is spiral. By rotating the plug-in port 1 or the connector shell 2, the movable card rod 52 moves in the clamping groove 11 along the length direction of the clamping groove 11, so that the plug-in port 1 and the connector shell 2 are tightly abutted, thereby ensuring the stability of the SHV coaxial connector when docking.

[0049] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the scope of protection determined by the claims submitted for the present invention.
