In such an environment, connectors are core components for connecting circuits, transmitting signals and electricity. Their performance and reliability are directly related to the safe and stable operation of nuclear power plants.

[0003] Although the radiation-resistant high-strength connectors in the prior art meet the basic requirements for radiation and strength to a certain extent, when performing the plug-in operation, there is always relative sliding between the male and female ends, which will inevitably generate a large amount of friction, accelerate the wear rate of the terminals, cause the corrosion resistance of the terminals to decrease, increase the contact resistance, and affect the quality of signal transmission. In addition, due to the heat generated by friction and the change of the local electric field, the probability of air breakdown discharge during the connection process increases significantly, which may cause damage to the electronic equipment and reduce the reliability and stability of the equipment operation.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments 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.

[0020] An embodiment of a radiation-resistant high-strength connector of the present invention is as follows Figures 1 to 11 shown.

[0021] A radiation-resistant high-strength connector includes a plug-in connector 100 and a conductive member 200. The plug-in connector 100 can move along a first direction toward a side close to the conductive member 200 and plug into the conductive member 200. The direction in which the plug-in connector 100 and the conductive member 200 are plugged into each other is referred to as the first direction. The plug-in 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 disposed in the first housing 110. The male terminal 140 and the female terminal 150 are disposed face to face in the first direction and connected by a connecting member 160. The male terminal 140 is located on a side of the female terminal 150 close to the first connecting frame 130 in the first direction. The conductive member 200 includes a second shell 210, in which a second connecting frame 220 is arranged. In an initial state, a gap is left between the male terminal 140 and the first connecting frame 130, and a gap is left 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.

[0022] The rotating sleeve 120 can be installed on the first shell 110 so as to rotate around a first direction. The rotating sleeve 120 can rotate around the first direction to move the connecting member 160. The movement of the connecting member 160 can move the male terminal 140 and the female terminal 150 in the first direction. The plug-in connection of the connector 100 and the conductive 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 leaves a gap between the male terminal 140 and the first connecting frame 130, and the female terminal 150 approaches the second connecting frame 220 and leaves 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.

[0023] The first shell 110 and the second shell 210 are both made of brass material, and the surface is treated with copper-nickel-chromium electroplating, and have good protection properties such as corrosion resistance and wear resistance.

[0024] In this embodiment, the first connecting frame 130 is provided to cooperate with the male terminal 140, and the second connecting frame 220 is provided to cooperate with the female terminal 150. When the plug connector 100 and the conductive member 200 need to be connected, the rotating sleeve 120 is rotated, and the rotating sleeve 120 drives the connecting member 160 to move, thereby moving the male terminal 140 and the female terminal 150 in the first direction. In the first stroke of the plug connector 100 and the conductive member 200, 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 connector 100 and the conductive member 200 are not connected to each other, preparing for the subsequent connection. In the second stroke of the plug-in connection between the plug-in connector 100 and the conductive member 200 , the male end abuts against the first connecting frame 130 , and the female terminal 150 abuts against the second connecting frame 220 , thereby achieving normal conduction between the plug-in connector 100 and the conductive member 200 .

[0025] 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 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 air discharge breakdown during the connection process is reduced, and the transmission stability is improved.

[0026] Specifically, the first connecting frame 130 includes a first frame 131 and a first connecting line 132, the first frame 131 is installed in the first housing 110, and the first connecting line 132 is installed on the first frame 131. The second connecting frame 220 includes a second frame 221 and a second connecting line 222, the second frame 221 is installed in the second housing 210, and the second connecting line 222 is installed on the second frame 221. The insulator wrapped around the first connecting line 132 and the second connecting line 222 is made of polyetheretherketone, which has flame retardant, wear resistance, corrosion resistance, impact resistance, hydrolysis resistance and other properties.

[0027] A limiting column 223 is disposed on the first frame 131 . The limiting column 223 is disposed along the first direction. The limiting column 223 is coaxially disposed with the male terminal 140 and the female terminal 150 . The limiting column 223 passes through the male terminal 140 and the female terminal 150 in sequence along the first direction and cooperates with the key slots of the male terminal 140 and the female terminal 150 .

[0028] By providing the limiting column 223 , the male terminal 140 and the female terminal 150 are restricted from rotating around the first direction, so that the male terminal 140 and the female terminal 150 can only move in the first direction.

[0029] In this embodiment, both the male terminal 140 and the female terminal 150 are conical structures. The first connecting frame 130 defines a first connecting space for matching with the male terminal 140, and the first connecting space is conical. The second connecting frame 220 defines a second connecting space for matching with the female terminal 150, and the second connecting space is conical.

[0030] By setting the tapered male terminal 140 and the female terminal 150, when the male terminal 140 moves along the first direction toward the side close to the first connecting frame 130, the male terminal 140 can abut against the first connecting frame 130, and when the female terminal 150 moves along the first direction toward the side close to the second connecting frame 220, the female terminal 150 can abut against the second connecting frame 220, and the electrically conductive contact surface is larger.

[0031] In this embodiment, the connector 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 arranged in sequence 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, and both the first connecting plate 163 and the second connecting plate 164 are elastic.

[0032] A plurality of rotating columns 121 are evenly distributed on the rotating sleeve 120 around the first direction, and a plurality of installation spaces 165 and a plurality of extrusion spaces 166 which are sequentially arranged and interconnected around the first direction are defined between the first connecting ring 161 and the second connecting ring 162, and the installation spaces 165 and the extrusion spaces 166 are alternately distributed around the first direction, and 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 thereto, and the size of the installation space 165 in the first direction is larger than the size of the extrusion space 166 in the first direction. The rotating column 121 can rotate from the installation space 165 corresponding thereto to the extrusion space 166 corresponding thereto, and make the first connecting ring 161 and the second connecting ring 162 move away from each other in the first direction.

[0033] Specifically, the connector 160 further includes a plurality of soft copper plates 167, which are evenly distributed around the first direction between the male terminal 140 and the female terminal 150. In the initial state, the soft copper plates 167 are bent, so that when the male terminal 140 and the female terminal 150 are away from each other in the first direction, the soft copper plates 167 have a margin for extension in the first direction. By providing a plurality of soft copper plates 167, the male terminal 140 and the female terminal 150 can be normally conductive.

[0034] Furthermore, the rotating column 121 has a first inclined surface and a second inclined surface, the first inclined surface is slidably matched with the first connecting ring 161, and the second inclined surface is slidably matched with the second connecting ring 162, and the rotating sleeve 120 rotates around the first direction to make the first connecting ring 161 slide along the first inclined surface and the second connecting ring 162 slide along the second inclined surface, thereby making the first connecting ring 161 and the second connecting ring 162 move away from or approach each other in the first direction.

[0035] The end surface of the rotating column 121 along the second direction toward the central axis of the first housing 110 in the first 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 connected, and the end where the angle between the two waists of the isosceles triangle on the rotating column 121 is located is called the tip. In the initial state, the tip is located at the connection between the first connecting ring 161 and the second connecting ring 162. The first inclined surface and the second inclined surface are the two waist sides of the rotating column 121 respectively. The rotation direction of the rotating sleeve 120 is the same as the direction of the tip.

[0036] In this embodiment, the first connecting ring 161, the second connecting ring 162 and the rotating column 121 are matched. When the plug connector 100 and the conductive member 200 need to be connected, the rotating sleeve 120 is rotated, and the rotating sleeve 120 drives the rotating column 121 to rotate synchronously. The rotating column 121 rotates from the installation space 165 corresponding to it to the extrusion space 166 corresponding to it, and squeezes the first connecting ring 161 and the second connecting ring 162, so that the first connecting ring 161 and the second connecting ring 162 are separated from each other in the first direction, and then the first connecting ring 161 causes the male terminal 140 to move toward the first connecting frame 130 along the first direction through the first connecting plate 163, so that the second connecting ring 162 passes through the second connecting plate 16 4, the female terminal 150 is forced to move toward the second connection frame 220 along the first direction. At this time, the first connection plate 163 and the second connection plate 164 are deformed under pressure. Because both the male terminal 140 and the female terminal 150 are conical structures, with the rotation of the rotating sleeve 120, in the first stroke of the male terminal 140 and the female terminal 150, the male terminal 140 is in the process of approaching the first connection frame 130, but there is still a gap between the male terminal 140 and the first connection frame 130. Similarly, the female terminal 150 is also in the process of approaching the second connection frame 220, but there is still a gap between the female terminal 150 and the second connection frame 220. The plug-in component 100 and the conductive component 200 are not mutually conductive, preparing for subsequent connection. In the second stroke of the male terminal 140 and the female terminal 150, the male terminal abuts against the first connection frame 130, and the female terminal 150 abuts against the second connection frame 220, so that the normal conduction between the plug-in component 100 and the conductive component 200 is achieved.

[0037] In this embodiment, the male terminal 140 and the female terminal 150 are connected via a first elastic member 170 . The first elastic member 170 is disposed along a first direction and is a tension spring.

[0038] 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 stretch and store force. When the connector 100 and the conductive member 200 need to be disconnected, the rotating sleeve 120 is rotated in the opposite direction, so that the rotating column 121 is rotated back from the extrusion space 166 corresponding to it to the installation space 165 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 along 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 along the first direction to the side away from the second connecting frame 220 and disconnect from the second connecting frame 220.

[0039] In another possible embodiment, two sealing rings 111 are coaxially and fixedly arranged in the first housing 110, and the two sealing rings 111 are arranged in sequence in the first direction, one sealing ring 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 ethylene propylene diene monomer rubber (EPDM), which has excellent cold resistance, heat resistance, radiation resistance, water resistance, corrosion resistance, acid and alkali resistance and good electrical insulation performance.

[0040] In this embodiment, two sealing rings 111 are provided. When the plug connector 100 is not plugged into the conductive member 200 , the sealing ring 111 sleeved on the male terminal 140 can isolate the male terminal 140 from the outside to a certain extent to prevent dust from entering.

[0041] In the process that the rotating column 121 rotates to make the first connecting ring 161 move the male terminal 140 through the first connecting plate 163, and makes the second connecting ring 162 move the female terminal 150 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 the male terminal 140 and the female terminal 150 after they pass the 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 plug-in speed and reducing the probability of air discharge breakdown during the connection process.

[0042] In this embodiment, the first housing 110 is threadedly matched with the second housing 210. The state after the first housing 110 and the second housing 210 are threadedly matched is called an initial state.

[0043] Specifically, the first shell 110 is provided with an external thread, and the second shell 210 is provided with an internal thread, and the internal thread is rotationally matched with the external thread.

[0044] The first housing 110 includes a first shell, a second shell and a mounting bracket 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 close to the second shell 210 in the first direction, and the external thread is provided on the first shell. The mounting bracket 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.

[0045] By screwing the first shell 110 and the second shell 210 together, when connecting, the first shell 110 and the second shell 210 are first locked. At this time, the radiation-resistant high-strength connector is in an initial state, but the male terminal 140 does not abut against the first connecting frame 130, and the female terminal 150 does not abut against the second connecting frame 220. The connection or interruption of the plug-in component 100 and the conductive component 200 is achieved by rotating the rotating sleeve 120. The connection and disconnection between the male terminal 140 and the female terminal 150 can be completed without plugging and unplugging operations, which makes the operation more convenient.

[0046] Further, the rotating sleeve 120 is provided with a plurality of long marks 122 and a plurality of short marks 123 in sequence around the first direction, and the long marks 122 and the short marks 123 are alternately distributed in sequence around the first direction, and the mounting frame 113 is provided with a matching mark 114, and the long marks 122 and the matching marks 114 are located on the same axis in the first direction in the initial state. When the male terminal 140 abuts against the first connecting frame 130, and the female terminal 150 abuts against the second connecting frame 220, the short marks 123 and the matching marks 114 are located on the same axis in the first direction.

[0047] Furthermore, an indicating arrow is marked on the mounting frame 113. When the operator needs to connect the plug connector 100 and the conducting member 200, the operator can rotate the rotating sleeve 120 in the direction of the indicating arrow, which is convenient for operation.

[0048] In combination with the above embodiments, the specific working process is as follows: During connection, the first housing 110 and the second housing 210 are locked first. At this time, the radiation-resistant high-strength connector is in an initial state, but the male terminal 140 does not abut against the first connecting frame 130 , and the female terminal 150 does not abut against the second connecting frame 220 .

[0049] When the plug connector 100 and the conductive member 200 need to be connected, the rotating sleeve 120 is rotated, and the rotating sleeve 120 drives the rotating column 121 to rotate synchronously. The rotating column 121 rotates from the installation space 165 corresponding to it to the extrusion space 166 corresponding to it, and squeezes the first connecting ring 161 and the second connecting ring 162, so that the first connecting ring 161 and the second connecting ring 162 are separated from each other in the first direction, and then the first connecting ring 161 causes the male terminal 140 to move toward the first connecting frame 130 along the first direction through the first connecting plate 163, so that the second connecting ring 162 causes the female terminal 150 to move toward the second connecting frame 130 along the first direction through the second connecting plate 164. The second connecting frame 220 moves to one side, and the first connecting plate 163 and the second connecting plate 164 are deformed under pressure. Because the male terminal 140 and the female terminal 150 are both conical structures, with the rotation of the rotating sleeve 120, in the first stroke of the plug-in connection of the plug-in component 100 and the conductive component 200, 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 component 100 and the conductive component 200 are not mutually conductive, preparing for subsequent connection.
