Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to a radiation-resistant high-strength connector. Background Art

[0002] In some special fields, electronic devices face extremely harsh working environments. Taking nuclear power plants as an example, as efficient energy production facilities, they are filled with various electronic devices inside, undertaking key tasks such as monitoring and controlling the operating status of nuclear reactors. In such an environment, as a core component for connecting circuits, transmitting signals, and power, the performance reliability of connectors is directly related to the safe and stable operation of nuclear power plants.

[0003] For the existing radiation-resistant high-strength connectors, although they meet the basic requirements for radiation and strength to a certain extent, when plugging and unplugging operations are performed, there is always relative sliding between the male end and the female end, which will inevitably generate a large amount of friction, accelerate the wear rate of the terminals, lead to a decrease in the corrosion resistance of the terminals, increase the contact resistance, affect the quality of signal transmission, and due to the heat generated by friction and the change of the local electric field, the probability of breakdown and air discharge during the connection process increases significantly, which may cause damage to electronic devices and reduce the reliability and stability of equipment operation. Summary of the Invention

[0004] The present invention provides a radiation-resistant high-strength connector to solve the problem that when the existing connectors are connected, due to the relative sliding between the male end and the female end, it will not only accelerate the wear rate of the terminals, but also damage the terminal plating layer and even cause damage to electronic devices.

[0005] The following technical solution is adopted for a radiation-resistant high-strength connector of the present invention: A radiation-resistant high-strength connector includes a plug-in member and a conduction member. The direction in which the plug-in member and the conduction member are plugged is referred to as the first direction; the plug-in member includes a first housing and a rotating sleeve. A first connecting frame, a male terminal, and a female terminal are arranged inside the first housing. The male terminal and the female terminal are arranged face to face in the first direction and are connected by a connecting member. The male terminal is located on the side of the female terminal closer to the first connecting frame in the first direction; the conduction member includes a second housing, and a second connecting frame is arranged inside the second housing. Initially, there is a gap between the male terminal and the first connecting frame, and there is a gap between the female terminal and the second connecting frame, and both the male terminal and the female terminal can move along the first direction; the rotating sleeve is rotatably mounted on the first housing around the first direction. Rotating the rotating sleeve around the first direction can cause the connecting member to act, and the action of the connecting member can cause the male terminal and the female terminal to move in the first direction. The plugging of the plug-in member and the conduction member has a first stroke and a second stroke. In the first stroke, the male terminal approaches the first connecting frame and there is a gap between the male terminal and the first connecting frame, and the female terminal approaches the second connecting frame and there is a gap between the female terminal and the second connecting frame. In the second stroke, the male terminal abuts against the first connecting frame, and the female terminal abuts against the second connecting frame.

[0006] Further, both the male terminal and the female terminal are conical structures; a first connecting space for cooperating with the male terminal is defined inside the first connecting frame, the first connecting space is conical, a second connecting space for cooperating with the female terminal is defined inside the second connecting frame, and the second connecting space is conical.

[0007] Further, the connecting member includes a first connecting ring and a second connecting ring; the male terminal, the first connecting ring, the second connecting ring, and the female terminal are arranged in sequence in the first direction. The male terminal is connected to the first connecting ring through a first connecting plate, the female terminal is connected to the second connecting ring through a second connecting plate, and both the first connecting plate and the second connecting plate are elastic; a plurality of rotating columns are evenly distributed around the first direction on the rotating sleeve. A plurality of installation spaces and a plurality of extrusion spaces that are arranged in sequence and communicate with each other around the first direction are defined between the first connecting ring and the second connecting ring, and the installation spaces and the extrusion spaces are alternately distributed in sequence around the first direction. The installation spaces, the extrusion spaces, and the rotating columns are arranged in one-to-one correspondence. Initially, each rotating column is installed in the installation space corresponding to it. The size of the installation space in the first direction is larger than the size of the extrusion space in the first direction. The rotating column can rotate from the installation space corresponding to it to the extrusion space corresponding to it, and cause the first connecting ring and the second connecting ring to move away from each other in the first direction.

[0008] Further, the rotating column has a first inclined surface and a second inclined surface. The first inclined surface is in sliding fit with the first connecting ring, and the second inclined surface is in sliding fit with the second connecting ring. When the rotating sleeve rotates around the first direction, the first connecting ring can slide along the first inclined surface, and the second connecting ring can slide along the second inclined surface, so that the first connecting ring and the second connecting ring move away from or close to each other in the first direction.

[0009] Further, the connecting member further includes a plurality of flexible copper plates. The plurality of flexible copper plates are evenly distributed around the first direction between the male terminal and the female terminal. In the initial state, the flexible copper plates are bent.

[0010] Further, the male terminal and the female terminal are connected by a first elastic member. The first elastic member is arranged along the first direction.

[0011] Further, two sealing rings are coaxially and fixedly arranged in the first housing. The two sealing rings are arranged in sequence in the first direction. One of the sealing rings is sleeved outside the male terminal, and the other sealing ring is sleeved outside the female terminal.

[0012] Further, the first housing is in threaded fit with the second housing.

[0013] Further, the first housing includes a first shell, a second shell and a mounting frame; the first shell and the second shell are arranged in sequence in the first direction. The first shell is located on the side of the second shell close to the second housing in the first direction. The mounting frame connects the first shell and the second shell. The rotating sleeve is rotatably mounted on the first shell and the second shell and is located between the first shell and the second shell.

[0014] Further, a plurality of long marks and a plurality of short marks are arranged in sequence around the first direction on the rotating sleeve, and the long marks and the short marks are alternately distributed in sequence around the first direction. A matching mark is arranged on the mounting frame. In the initial state, the long mark and the matching mark are on the same axis in the first direction; when the male terminal abuts against the first connecting frame and the female terminal abuts against the second connecting frame, the short mark and the matching mark are on the same axis in the first direction.

[0015] The beneficial effects of the present invention are as follows: By dividing the connection between the male terminal and the first connecting frame and the connection between the female terminal and the second connecting frame into two strokes, a radiation-resistant high-strength connector of the present invention shortens the relative sliding distance between the male terminal and the first connecting frame and between the female terminal and the second connecting frame, slows down the wear of the male terminal and the female terminal, reduces the probability of breakdown and air discharge during the connection process, and improves the transmission stability.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] An embodiment of a radiation-resistant high-strength connector of the present invention is as Figures 1 to 11 shown.

[0031] A radiation-resistant high-strength connector includes a connector 100 and a conducting member 200. The connector 100 can move along a first direction toward the side close to the conducting member 200 and be inserted into the conducting member 200. The direction in which the connector 100 and the conducting member 200 are inserted is called the first direction. The connector 100 includes a first housing 110 and a rotating sleeve 120. A first connecting frame 130, a male terminal 140, and a female terminal 150 are arranged in the first housing 110. The male terminal 140 and the female terminal 150 are arranged face to face in the first direction and are connected by a connecting member 160. The male terminal 140 is located on the side of the female terminal 150 close to the first connecting frame 130 in the first direction. The conducting member 200 includes a second housing 210. A second connecting frame 220 is arranged in the second housing 210. In an initial state, there is a gap between the male terminal 140 and the first connecting frame 130, and there is a gap between the female terminal 150 and the second connecting frame 220, and both the male terminal 140 and the female terminal 150 can move along the first direction.

[0032] The rotating sleeve 120 is rotatably mounted on the first housing 110 about the first direction. The rotation of the rotating sleeve 120 about the first direction can cause the connecting member 160 to act. The actuation of the connecting member 160 can cause the male terminal 140 and the female terminal 150 to move in the first direction. The insertion of the plug-in member 100 and the conduction member 200 has a first stroke and a second stroke. In the first stroke, the male terminal 140 approaches the first connecting frame 130 and there is a gap between the male terminal 140 and the first connecting frame 130. The female terminal 150 approaches the second connecting frame 220 and there is a gap between the female terminal 150 and the second connecting frame 220. In the second stroke, the male terminal 140 abuts against the first connecting frame 130, and the female terminal 150 abuts against the second connecting frame 220.

[0033] Both the first housing 110 and the second housing 210 are made of brass material and are surface-treated with copper-nickel-chromium electroplating, having good protective properties such as corrosion resistance and wear resistance.

[0034] In this embodiment, by setting the first connecting frame 130 to cooperate with the male terminal 140 and the second connecting frame 220 to cooperate with the female terminal 150, when it is necessary to connect the plug-in member 100 and the conduction member 200, the rotating sleeve 120 is rotated. The rotation of the rotating sleeve 120 will drive the connecting member 160 to act, and further cause the male terminal 140 and the female terminal 150 to move in the first direction. In the first stroke of the insertion of the plug-in member 100 and the conduction member 200, at this time, the male terminal 140 is in the process of approaching the first connecting frame 130, but there is still a gap between the male terminal 140 and the first connecting frame 130. Similarly, the female terminal 150 is also in the process of approaching the second connecting frame 220, but there is still a gap between the female terminal 150 and the second connecting frame 220. The plug-in member 100 and the conduction member 200 are not electrically connected to each other, preparing for subsequent connection. In the second stroke of the insertion of the plug-in member 100 and the conduction member 200, the male terminal abuts against the first connecting frame 130, and the female terminal 150 abuts against the second connecting frame 220, realizing the normal conduction of the plug-in member 100 and the conduction member 200.

[0035] By dividing the connection between the male terminal 140 and the first connecting frame 130 and the connection between the female terminal 150 and the second connecting frame 220 into two strokes, the relative sliding distance between the male terminal 140 and the first connecting frame 130 and between the female terminal 150 and the second connecting frame 220 is shortened, the wear of the male terminal 140 and the female terminal 150 is reduced, the probability of breakdown air discharge during the connection process is lowered, and the transmission stability is improved.

[0036] Specifically, the first connecting bracket 130 includes a first bracket body 131 and a first connecting wire 132. The first bracket body 131 is installed inside the first outer shell 110, and the first connecting wire 132 is installed on the first bracket body 131. The second connecting bracket 220 includes a second bracket body 221 and a second connecting wire 222. The second bracket body 221 is installed inside the second outer shell 210, and the second connecting wire 222 is installed on the second bracket body 221. The insulators wrapped around the first connecting wire 132 and the second connecting wire 222 are made of polyether ether ketone, which has properties such as flame retardancy, wear resistance, corrosion resistance, impact resistance, and hydrolysis resistance.

[0037] A limiting post 223 is provided on the first bracket body 131. The limiting post 223 is arranged along the first direction. The limiting post 223 is coaxially arranged with the male terminal 140 and the female terminal 150. The limiting post 223 sequentially passes through the male terminal 140 and the female terminal 150 along the first direction, and is in keyway fit with the male terminal 140 and the female terminal 150.

[0038] By providing the limiting post 223, the rotation of the male terminal 140 and the female terminal 150 around the first direction is restricted, so that the male terminal 140 and the female terminal 150 can only move in the first direction.

[0039] In this embodiment, both the male terminal 140 and the female terminal 150 are of a conical structure. A first connection space for cooperating with the male terminal 140 is defined inside the first connecting bracket 130, and the first connection space is conical. A second connection space for cooperating with the female terminal 150 is defined inside the second connecting bracket 220, and the second connection space is conical.

[0040] By providing the conical male terminal 140 and female terminal 150, when the male terminal 140 moves along the first direction towards the side close to the first connecting bracket 130, the male terminal 140 can abut against the first connecting bracket 130. When the female terminal 150 moves along the first direction towards the side close to the second connecting bracket 220, the female terminal 150 can abut against the second connecting bracket 220, and the charged contact surface is larger.

[0041] In this embodiment, the connecting member 160 includes a first connecting ring 161 and a second connecting ring 162. The male terminal 140, the first connecting ring 161, the second connecting ring 162, and the female terminal 150 are sequentially arranged in the first direction. The male terminal 140 is connected to the first connecting ring 161 through a first connecting plate 163, and the female terminal 150 is connected to the second connecting ring 162 through a second connecting plate 164. Both the first connecting plate 163 and the second connecting plate 164 are elastic.

[0042] A plurality of rotating columns 121 are evenly distributed around the first direction on the rotating sleeve 120. A plurality of installation spaces 165 and a plurality of extrusion spaces 166 are defined between the first connecting ring 161 and the second connecting ring 162, which are arranged in sequence and communicate with each other around the first direction, and the installation spaces 165 and the extrusion spaces 166 are alternately distributed in sequence around the first direction. The installation spaces 165, the extrusion spaces 166 and the rotating columns 121 are arranged in one-to-one correspondence. In the initial state, each rotating column 121 is installed in the installation space 165 corresponding to it. The dimension of the installation space 165 in the first direction is larger than the dimension of the extrusion space 166 in the first direction. The rotating column 121 can rotate from the installation space 165 corresponding to it to the extrusion space 166 corresponding to it, and make the first connecting ring 161 and the second connecting ring 162 move away from each other in the first direction.

[0043] Specifically, the connecting member 160 further includes a plurality of flexible copper plates 167, and the plurality of flexible copper plates 167 are evenly distributed around the first direction between the male terminal 140 and the female terminal 150. In the initial state, the flexible copper plates 167 are bent, so that when the male terminal 140 and the female terminal 150 move away from each other in the first direction, the flexible copper plates 167 have a margin for elongation in the first direction. By providing a plurality of flexible copper plates 167, the male terminal 140 and the female terminal 150 can be normally conducted.

[0044] Furthermore, the rotating column 121 has a first inclined surface and a second inclined surface. The first inclined surface is in sliding fit with the first connecting ring 161, and the second inclined surface is in sliding fit with the second connecting ring 162. Rotating the rotating sleeve 120 around the first direction can make the first connecting ring 161 slide along the first inclined surface and the second connecting ring 162 slide along the second inclined surface, so that the first connecting ring 161 and the second connecting ring 162 move away from or close to each other in the first direction.

[0045] The end surface of the rotating column 121 facing the side of the central axis of the first housing 110 in the first direction along the second direction is an isosceles triangle, and the second direction is perpendicular to the first direction. In the initial state, the first connecting ring 161 and the second connecting ring 162 are docked. One end where the included angle between the two waists forming the isosceles triangle on the rotating column 121 is called the tip. In the initial state, the tip is located at the docking position of the first connecting ring 161 and the second connecting ring 162. The first inclined surface and the second inclined surface are respectively two waist edges of the rotating column 121. The rotating direction of the rotating sleeve 120 is the same as the orientation of the tip.

[0046] In this embodiment, by setting the cooperation of the first connecting ring 161, the second connecting ring 162 and the rotating column 121, when it is necessary to connect the plug-in member 100 and the conducting member 200, the rotating sleeve 120 is rotated. The rotating sleeve 120 will drive the rotating column 121 to rotate synchronously. The rotating column 121 will rotate from the installation space 165 provided corresponding to it to the extrusion space 166 provided corresponding to it, and extrude the first connecting ring 161 and the second connecting ring 162, so that the first connecting ring 161 and the second connecting ring 162 move away from each other in the first direction. Furthermore, the first connecting ring 161 urges the male terminal 140 to move toward the first connecting frame 130 side in the first direction through the first connecting plate 163, and the second connecting ring 162 urges the female terminal 150 to move toward the second connecting frame 220 side in the first direction through the second connecting plate 164. At this time, the first connecting plate 163 and the second connecting plate 164 are deformed under pressure. Also, because both the male terminal 140 and the female terminal 150 are conical structures, as the rotating sleeve 120 rotates, during the first stroke of the movement of the male terminal 140 and the female terminal 150, at this time the male terminal 140 is in the process of approaching the first connecting frame 130, but there is still a gap between the male terminal 140 and the first connecting frame 130. Similarly, the female terminal 150 is also in the process of approaching the second connecting frame 220, but there is still a gap between the female terminal 150 and the second connecting frame 220. The plug-in member 100 and the conducting member 200 are not electrically connected to each other, preparing for subsequent connection. During the second stroke of the movement of the male terminal 140 and the female terminal 150, the male terminal abuts against the first connecting frame 130, and the female terminal 150 abuts against the second connecting frame 220, realizing the normal conduction between the plug-in member 100 and the conducting member 200.

[0047] In this embodiment, the male terminal 140 and the female terminal 150 are connected by a first elastic member 170. The first elastic member 170 is arranged in the first direction, and the first elastic member 170 is a tension spring.

[0048] By setting the first elastic member 170, when the male terminal 140 and the female terminal 150 move away from each other in the first direction, the first elastic member 170 will be stretched and store energy. When it is necessary to disconnect the plug-in member 100 and the conducting member 200, the rotating sleeve 120 is rotated in the reverse direction, and then the rotating column 121 is rotated back from the extrusion space 166 provided corresponding to it to the installation space 165 provided corresponding to it. At this time, under the action of the first elastic member 170, the first connecting plate 163 and the second connecting plate 164, the male terminal 140 will move in the first direction to the side away from the first connecting frame 130 and disconnect from the first connecting frame 130. Similarly, the female terminal 150 will move in the first direction to the side away from the second connecting frame 220 and disconnect from the second connecting frame 220.

[0049] In another possible embodiment, two sealing rings 111 are coaxially and fixedly arranged inside the first housing 110. The two sealing rings 111 are arranged in sequence in the first direction. One of the sealing rings 111 is sleeved outside the male terminal 140, and the other sealing ring 111 is sleeved outside the female terminal 150. The material of the sealing ring 111 is selected as ethylene propylene diene monomer (EPDM), which has excellent cold resistance, heat resistance, radiation resistance, water resistance, corrosion resistance, acid and alkali resistance, and good electrical insulation performance.

[0050] In this embodiment, by arranging two sealing rings 111, when the connector 100 is not inserted into the conducting member 200, the sealing ring 111 sleeved on the male terminal 140 can separate the male terminal 140 from the outside to a certain extent and prevent dust from entering.

[0051] Moreover, during the process that the rotating column 121 rotates to make the first connecting ring 161 drive the male terminal 140 to move through the first connecting plate 163 and make the second connecting ring 162 drive the female terminal 150 to move through the second connecting plate 164, the setting of the sealing ring 111 can reduce the moving speed of the male terminal 140 and the female terminal 150, and quickly release after the male terminal 140 and the female terminal 150 pass over their corresponding sealing rings 111, so that the male terminal 140 immediately abuts against the first connecting frame 130, and the female terminal 150 immediately abuts against the second connecting frame 220, further improving the insertion speed and reducing the probability of breakdown and air discharge during the connection process.

[0052] In this embodiment, the first housing 110 is in threaded fit with the second housing 210. The state after the first housing 110 and the second housing 210 are in threaded fit is called the initial state.

[0053] Specifically, external threads are provided on the first housing 110, and internal threads are provided on the second housing 210. The internal threads are in rotational fit with the external threads.

[0054] The first housing 110 includes a first shell, a second shell and a mounting frame 113. The first shell and the second shell are arranged in sequence in the first direction. The first shell is located on the side of the second shell closer to the second housing 210 in the first direction, and the external threads are provided on the first shell. The mounting frame 113 connects the first shell and the second shell. The rotating sleeve 120 is rotatably mounted on the first shell and the second shell and is located between the first shell and the second shell.

[0055] By screwing the first housing 110 and the second housing 210 together, when connecting, first lock the first housing 110 and the second housing 210. At this time, the radiation-resistant high-strength connector is in the initial state, but the male terminal 140 does not abut against the first connection bracket 130, and the female terminal 150 does not abut against the second connection bracket 220. By rotating the rotating sleeve 120, the connection or interruption between the plug-in member 100 and the conduction member 200 can be achieved, and the on-off between the male terminal 140 and the female terminal 150 can be completed without the need for plugging and unplugging operations, making the use operation more convenient.

[0056] Furthermore, a plurality of long marks 122 and a plurality of short marks 123 are sequentially arranged around the first direction on the rotating sleeve 120, and the long marks 122 and the short marks 123 are alternately distributed in sequence around the first direction. A matching mark 114 is arranged on the mounting bracket 113. In the initial state, the long mark 122 and the matching mark 114 are on the same axis in the first direction. When the male terminal 140 abuts against the first connection bracket 130 and the female terminal 150 abuts against the second connection bracket 220, the short mark 123 and the matching mark 114 are on the same axis in the first direction.

[0057] Even further, an indicating arrow is marked on the mounting bracket 113. When an operator needs to conduct the plug-in member 100 and the conduction member 200, the rotating sleeve 120 can be rotated in the direction of the indicating arrow, which is convenient for operation.

[0058] Combined with the above embodiments, the specific working process is as follows:

[0059] When connecting, first lock the first housing 110 and the second housing 210. At this time, the radiation-resistant high-strength connector is in the initial state, but the male terminal 140 does not abut against the first connection bracket 130, and the female terminal 150 does not abut against the second connection bracket 220.

[0060] When it is necessary to connect the connector 100 and the conduction member 200, rotate the rotating sleeve 120. The rotating sleeve 120 will drive the rotating column 121 to rotate synchronously. The rotating column 121 will rotate from the installation space 165 provided corresponding to it to the extrusion space 166 provided corresponding to it, and squeeze the first connecting ring 161 and the second connecting ring 162, so that the first connecting ring 161 and the second connecting ring 162 move away from each other in the first direction. Furthermore, the first connecting ring 161 urges the male terminal 140 to move toward the first connecting frame 130 in the first direction through the first connecting plate 163, and the second connecting ring 162 urges the female terminal 150 to move toward the second connecting frame 220 in the first direction through the second connecting plate 164. At this time, the first connecting plate 163 and the second connecting plate 164 are deformed under pressure. Also, because both the male terminal 140 and the female terminal 150 are conical structures, as the rotating sleeve 120 rotates, during the first stroke of the insertion of the connector 100 and the conduction member 200, at this time, the male terminal 140 is in the process of approaching the first connecting frame 130, but there is still a gap between the male terminal 140 and the first connecting frame 130. Similarly, the female terminal 150 is also in the process of approaching the second connecting frame 220, but there is still a gap between the female terminal 150 and the second connecting frame 220. The connector 100 and the conduction member 200 are not electrically connected to each other, preparing for subsequent connection. In the second stroke of the insertion of the connector 100 and the conduction member 200, the male terminal abuts against the first connecting frame 130, and the female terminal 150 abuts against the second connecting frame 220, realizing the normal conduction between the connector 100 and the conduction member 200.

[0061] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
