Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the present application.

[0042] The technical problems existing in the prior art are:

[0043] In the technical field of feeder connector, the quality of smooth outer conductor feeder connector has a very important influence on the information transmission speed and quality of the connected feeder. In this technical field, there are usually two types of outer conductors of the feeder, one type of outer conductor is a smooth conductor, and the other type of outer conductor is a corrugated tube type conductor with wave peaks and valleys. Generally speaking, the smooth outer conductor feeder surface has the following problems in the process of connecting with the connector:

[0044] 1. The connection stability between the connector and the feeder is affected. For example, after the feeder is assembled with the connector, the feeder may swing or rotate during use. In the process of swinging or rotating, the slot gap of the cable clamp in the connector for clamping the feeder will become larger. The clamping force of the cable clamp on the smooth outer conductor feeder is smaller than that on the corrugated tube outer conductor feeder, and even the feeder may fall off from the connector, thereby affecting the normal use of the connector.

[0045] 2. The insertion end of the smooth outer conductor feeder is more easily damaged. For example, during the process of inserting the feeder into the connector, the operator usually feels that it cannot be inserted, and then judges that the feeder is inserted into the connector. The corrugated tube has a wave peak and valley structure on the outer conductor, and the friction between the corrugated tube and the connector is larger. When the corrugated tube is inserted into the connector under external force, the insertion end of the corrugated tube moves to the connector at a relatively small speed. In comparison, the friction between the smooth outer conductor feeder and the connector is smaller. When the smooth outer conductor feeder is inserted into the connector under external force, the insertion end of the smooth outer conductor feeder moves in the connector at a relatively fast speed, thereby causing greater damage to the insertion end of the smooth outer conductor feeder when it is inserted into the connector.

[0046] Therefore, the present application provides a smooth outer conductor feeder connector. The connector is in the shape of a cylinder as a whole, as shown in FIGS. 1-14, which comprises a sleeve 10, a middle shell 20 and a rear shell 30. One end of the middle shell 20 is detachably connected with the sleeve 10, and the other end is detachably connected with the rear shell 30.

[0047] Exemplarily, along the x direction, the screw sleeve 10, the middle shell 20 and the rear shell 30 are sequentially arranged, wherein one end of the screw sleeve 10 and one end of the middle shell 20 can be connected in a threaded connection, a snap ring connection or the like, for example, in a snap ring connection, so that the screw sleeve 10 can rotate. The other end of the middle shell 20 and the rear shell 30 can be connected in a threaded connection, a snap connection, a press connection or the like. In the embodiment, the middle shell 20 and the rear shell 30 are preferably press-connected, which can make the feeder and the connector more firmly connected and not loose due to vibration or shaking during use.

[0048] The cable clamp 40 is fixedly installed in the receiving cavity of the middle shell 20, and exemplarily, the cable clamp 40 can be press-fitted into the receiving cavity of the middle shell 20 to ensure its stability. The cable clamp 40 includes a clamping portion 41 and a connecting portion 42, and the clamping portion 41 is circumferentially spaced apart to have a contraction groove 411 extending along the axial direction of the clamping portion 41. Exemplarily, along the x direction, one end of the cable clamp 40 adjacent to the screw sleeve 10 is the connecting portion 42, which is used to connect with the insulator 60 and the like, and the other end adjacent to the rear shell 30 is the clamping portion 41, which is used to clamp the feeder when the feeder is inserted into the cable clamp 40, to ensure the stable connection between the feeder and the cable clamp 40. In some alternative embodiments, the clamping portion 41 of the cable clamp 40 is spaced apart to have the contraction groove 411 on the outer wall in the circumferential direction, the contraction groove 411 extends along the x direction, and the contraction groove 411 penetrates through the end of the clamping portion 41 adjacent to the rear shell 30. The clamping portion 41 has two states, when the feeder is not inserted into the clamping portion 41, the contraction groove 411 is in a contracted state, and the slot gap of the contraction groove 411 is small; when the feeder is inserted into the clamping portion 41, the contraction groove 411 is in an expanded state, the slot gap of the contraction groove 411 is increased, and the inner wall of the clamping portion 41 abuts against the feeder, thereby reducing the displacement of the feeder after being inserted into place.

[0049] The fastener 50 is circumferentially arranged on the outer peripheral wall of the cable clamp 40, and when the feeder is inserted into place in the connector, the fastener 50 is used to limit the relative movement of the feeder and the connector.

[0050] For example, the fastener 50 is circumferentially arranged on the outer circumferential wall of the clamping portion 41 of the cable clamp 40. After the feeder cable is inserted into the connector, the fastener 50 can exert a radial clamping force on the clamping portion 41, so that the clamping portion 41 is more tightly clamped on the cable clamp, and the two are more closely attached. In some alternative embodiments, the fastener 50 can be a fastening rod, one end of which abuts against the outer circumferential wall of the clamping portion 41 after the feeder cable is inserted into the connector, so that the clamping portion 41 is more tightly clamped on the cable clamp. In some alternative embodiments, the fastener 50 can also be a fastening ring, which is sleeved on the outer circumferential wall of the clamping portion 41. After the feeder cable is inserted into the connector, the fastening ring is tightened to make the clamping portion 41 more tightly clamped on the feeder cable. After the feeder cable is inserted into the connector, when the feeder cable swings or rotates or vibrates during use, the swinging force of the feeder cable can make the slot gap of the contraction groove 411 all or partially increase, the clamping force of the clamping portion 41 decreases, the feeder cable does not sufficiently contact the cable clamp 40, and the feeder cable is easily detached from the cable clamp 40, which causes problems such as signal transmission interruption and instability of the connector. By circumferentially arranging the fastener 50 on the outer circumferential wall of the clamping portion 41, after the feeder cable is inserted into the connector, the fastener 50 can provide a radial tightening force on the clamping portion 41, so that the clamping portion 41 is more tightly clamped on the feeder cable, and the feeder cable is sufficiently contacted with the clamping portion 41. When the part of the feeder cable outside the connector swings or rotates, the part of the feeder cable inside the connector is less affected, and this part basically does not rotate or swing relative to the clamping portion 41. The slot gap of the contraction groove 411 on the clamping portion 41 changes little, the axial or radial displacement of the feeder cable relative to the clamping portion 41 of the connector is limited, and the reliability of the smooth outer conductor feeder cable connector is ensured.

[0051] The insulator 60 is fixedly connected in the connecting portion 42;

[0052] The limiting member 70 is slidably installed in the insulator 60, one end of the limiting member 70 can abut against the feeder cable, and is used to judge the connection state of the feeder cable and the connector.

[0053] In the above scheme, the connecting portion 42 of the cable clamp is adjacent to the sleeve 10, one end of the connecting portion 42 adjacent to the sleeve 10 is connected with the insulator 60, and the insulator 60 can be fixedly installed in the connecting portion 42 in a press-fit manner. For example, a positioning step is arranged on the inner wall of the connecting portion 42 adjacent to the sleeve 10, and the insulator 60 can be effectively fixed in cooperation with other components, so as to ensure that the insulator 60 does not move in the x direction when the feeder is inserted. The insulator 60 is provided with a sliding groove at least in the x direction, and the limiting piece 70 is slidingly installed in the sliding groove. During the insertion of the feeder into the connector, the insertion end of the feeder can push the limiting piece 70 to move in the x direction (the insertion direction), and the connection state of the feeder and the connector can be judged by the movement of the limiting piece 70. For example, when the feeder pushes the limiting piece 70 to move to a preset position, the limiting piece 70 emits a sound prompt, indicating that the feeder is connected to the connector in place. In some optional embodiments, whether the feeder is connected to the connector in place can be judged by obtaining the distance of the movement of the limiting piece 70 in the x direction. Through the arrangement of the limiting piece 70, during the insertion of the feeder into the connector, whether the feeder is inserted into the connector in place can be judged by the movement state or displacement of the limiting piece 70, so that the operator can timely master the insertion state of the feeder in the connector, and facilitate the operator to accurately control the insertion distance and the force applied to the feeder subsequently. Meanwhile, after the feeder is judged to be inserted into the connector in place by the limiting piece 70, compared with the judgment of the insertion of the feeder into the connector in place by the operator according to the immovability of the feeder in the connector, the damage to the feeder, especially the insertion end of the feeder, is greatly reduced, and the accuracy of signal transmission of the feeder is improved.

[0054] Therefore, the smooth outer conductor feeder connector provided in the application is provided with the fastener 50 which is arranged in the circumferential direction of the outer peripheral wall of the clamping portion 41 of the cable clamp 40. When the feeder is inserted into the connector in place, the fastener 50 applies a tightening force to the radial direction of the clamping portion 41, so that the clamping portion 41 is more closely attached to the feeder, and the clamping of the feeder is more firm. When the feeder located outside the connector is swung or rotated, the feeder located inside the connector will not be affected, so that the normal work of the connector is ensured. Meanwhile, the limiting piece 70 is arranged in the axial direction of the insulator, and the feeder can push the limiting piece 70 to move during the insertion of the feeder into the connector. Whether the feeder is inserted into the connector in place can be judged by the movement state or displacement of the limiting piece 70, so that the insertion end of the feeder is less damaged.

[0055] According to some optional embodiments, the fastener 50 includes a first sliding rod 51 and a first stopper 52, and the first stopper 52 is sleeved on the first sliding rod 51. The first sliding rod 51 is slidingly installed on the side wall of the middle shell 20, and when the feeder is inserted into the connector in place, the first sliding rod 51 can slide to the first end thereof which abuts against the outer peripheral wall of the cable clamp 40, and the first stopper 52 is used to keep the first sliding rod 51 in the middle shell 20.

[0056] In the above scheme, a sliding groove is arranged in the radial direction (y direction) of the middle shell 20, and the first sliding rod 51 is slidingly installed in the sliding groove and can slide relative to the clamping portion 41 of the cable clamp 40. During the process of inserting the feeder into the clamping portion 41, the clamping portion 41 will expand, thereby pushing the first sliding rod 51 away from the second end of the cable clamp 40 to slide out of the sliding groove to the outer wall of the middle shell 20. When the operator observes that the second end of the first sliding rod 51 protrudes from the middle shell 20, it indicates that the feeder has been inserted to the position of the first sliding rod 51. In order to reduce the damage to the insertion end of the feeder, the operator needs to slowly insert the feeder into the connector at this time. After judging that the feeder is inserted in place through the limiting piece 70, the rear shell 30 is crimped with the middle shell 20, the inner wall of the rear shell 30 pushes the second end of the first sliding rod 51 into the sliding groove of the middle shell 20, and the first end of the first sliding rod 51 abuts against the outer peripheral wall of the clamping portion 41, so that the clamping portion 41 is more closely connected with the feeder.

[0057] In some optional embodiments, the first sliding rod 51 is sleeved with a first stop piece 52. The first stop piece 52 is in a contracted state when it follows the first sliding rod 51 into the middle shell 20, so as to ensure that it can smoothly slide into the middle shell 20. The first stop piece 52 is in an expanded state after entering the middle shell 20. The maximum cross-sectional dimension of the expanded first stop piece 52 is greater than the dimension of the sliding groove, so as to avoid that the first sliding rod 51 automatically slides out after being inserted into the middle shell 20.

[0058] In some optional embodiments, the maximum dimension of the cross section of the first end of the first sliding rod 51 is greater than the width of the contraction groove 411 in the y direction. This arrangement can avoid that the first end of the first sliding rod 51 is clamped into the contraction groove 411 when it abuts against the clamping portion 41.

[0059] In some optional embodiments, in the x direction, the sliding stroke between the inner wall of the end of the rear shell 30 and the outer wall of the end of the middle shell 20 is L2, the crimping stroke between the outer wall of the front end of the rear shell 30 and the opposite wall of the positioning boss 21 on the outer wall of the middle shell 20 is L1, and the crimping stroke L1 is less than the sliding stroke L2. This arrangement can ensure that the first sliding rod 51 is first pressed down by the rear shell and is stopped by the inner wall of the rear shell, so as to ensure the close contact of the feeder and the cable clamp 40.

[0060] Preferably, the first sliding rod 51 and the first stop piece 52 can be made of elastic materials such as tin bronze or beryllium bronze.

[0061] According to some optional embodiments, the first sliding rod 51 includes a plurality of first sub-sliding rods 511, the first stop piece 52 includes a plurality of first sub-stop pieces, and the first sub-stop pieces are sleeved on the first sub-sliding rods 511. The first sub-sliding rods 511 can be 2, 3, 4, 6, etc., and the number of the first sub-stop pieces is the same as the number of the first sub-sliding rods 511.

[0062] The plurality of first sub-sliding rods 511 are distributed around the outer peripheral wall of the cable clamp 40, and two adjacent first sub-sliding rods 511 are connected by the first spring 54.

[0063] In the above scheme, when the feeder is subjected to vibration, swing, and rotation, the first sub-sliding rod 511 can slip or tilt relative to the cable clamp 40. Since the two adjacent first sub-sliding rods 511 are connected by the first spring 54, on the one hand, the first spring 54 can absorb part of the vibration received by the cable clamp 40, reducing the vibration received by the first sub-sliding rod 511. On the other hand, due to the elastic force of the first spring 54, when the cable clamp 40 is subjected to swing or rotation, the gap of the contraction groove 411 of the clamping part 41 of the cable clamp 40 will become larger. At this time, under the action of the elastic force of the first spring 54, the gap can be avoided from becoming larger, and the position of the first sub-sliding rod 511 abutting against the cable clamp 40 remains unchanged. On the other hand, when the first sub-sliding rod 511 is displaced, it will also return to the initial position under the action of the first spring 54, and will not tilt or slip.

[0064] In some optional embodiments, the distance between the two adjacent first sub-sliding rods 511 is L3, the distance between the adjacent edges of the two adjacent contraction grooves 411 is L4, and L4 < L3 < 2L4. Through such a setting, at least one of the two adjacent first sub-sliding rods 511 abuts against the outer peripheral wall of the clamping part 41, that is, between the two adjacent contraction grooves 411 of the clamping part 41, avoiding that both of the two adjacent first sub-sliding rods 511 abut against the contraction groove 411, and when the contraction groove 411 expands, both of the two adjacent first sub-sliding rods 511 are clamped into the contraction groove 411.

[0065] According to some optional embodiments, the fastener 50 includes a second spring 53, and the second spring 53 is sleeved on the outer peripheral wall of the cable clamp 40.

[0066] In the above scheme, the second spring 53 is a ring spring. After the feeder is inserted into the clamping part 41, the second spring 53 makes the clamping part 41 tightly clamp the feeder under the action of the elastic force. When the feeder is subjected to vibration, swing, and rotation, the second spring 53 can absorb the vibration generated by the cable clamp 40, and can also make the gap of the contraction groove 411 become larger when the clamping part 41 is subjected to swing or rotation. At this time, the second spring 53 will generate a force opposite to the expansion direction of the contraction groove 411 to reduce the expansion of the contraction groove 411, so that the cable clamp 40 and the feeder remain tightly connected.

[0067] According to some optional embodiments, the shape of the first end of the first slide rod 51 is adapted to the shape of the corresponding position of the outer peripheral wall of the cable clamp 40. For example, if the position of the outer wall of the clamping part 41 abutting the first end of the first slide rod 51 is circular, the shape of the first end of the first slide rod 51 is also circular; if the position of the outer peripheral wall of the clamping part 41 abutting the first end of the first slide rod 51 is a groove, the shape of the first end of the first slide rod 51 is a protrusion. Through such a design, the first end of the first slide rod 51 can have a large contact area with the outer peripheral wall of the clamping part 41, and abut the outer peripheral wall of the clamping part 41 more firmly, thereby making the contact between the clamping part 41 and the feeder more close.

[0068] According to some optional embodiments, the limiting member 70 includes a second slide rod 71 and a third slide rod 72. The second slide rod 71 is arranged to slide along the radial direction of the insulator 60, and the lower end of the second slide rod 71 is connected with a third spring 73. The third slide rod 72 is arranged perpendicularly to the second slide rod 71. When the feeder is inserted into the connector, the feeder can abut the third slide rod 72 and push the third slide rod 72 to slide to be connected with the second slide rod 71.

[0069] In the above scheme, the insulator 60 is provided with a longitudinal sliding groove and a transverse sliding groove in the y direction, and the longitudinal sliding groove and the transverse sliding groove are arranged in communication. The second slide rod 71 is installed in the longitudinal sliding groove, and the lower end of the second slide rod 71 is connected with the third spring 73, which is used to drive the second slide rod 71 to move towards the third slide rod 72. The third slide rod 72 is installed in the transverse sliding groove, and the third slide rod 72 is provided with a clamping hole or a clamping groove in the y direction. During the process of inserting the feeder into the connector, the insertion end of the feeder can abut the third slide rod 72 and push the third slide rod 72 to slide in the x direction. During the sliding process of the third slide rod 72, one end of the second slide rod 71 will slide into the clamping hole or the clamping groove under the action of the third spring 73, and a click sound will be emitted at the same time. At this time, it can be judged that the feeder is inserted in place through the sound, and damage to the feeder caused by not knowing that the feeder is inserted in place until the feeder is inserted immovably can be avoided.

[0070] Preferably, the second slide rod 71 and the third slide rod 72 are made of POM insulating material.

[0071] According to some optional embodiments, the end of the third slide rod 72 away from the cable clamp 40 is connected with a fourth spring 74, and the other end of the fourth spring 74 is fixedly connected with the insulator 60.

[0073] In some optional embodiments, a displacement sensor is installed on the transverse chute or the fourth spring 74, the displacement sensor can obtain the compression distance of the fourth spring 74, on the one hand, when the feeder line pushes the fourth spring 74 to move when sliding against the third slide rod 72, the position of the feeder line in the connector can be determined by the compression distance of the fourth spring 74 obtained in real time, so as to facilitate the operator to control the force and speed of inserting the feeder line; on the other hand, after the feeder line is inserted into the connector, when the feeder line vibrates, rotates, swings and other actions occur in the process of use, the connection state between the feeder line and the connector may be affected, at this time, the connection state between the feeder line and the connector can be determined by the extension distance of the fourth spring 74 obtained in real time, if the extension distance of the fourth spring 74 is less than the preset extension distance, it means that the feeder line and the connector are in a connected state, if the extension distance of the fourth spring 74 is greater than the preset extension distance, it means that the feeder line and the connector are in a disconnected state, at this time, the operator needs to be repaired.

[0074] According to some optional embodiments, a containing groove 503 is formed on the outer peripheral wall of the first slide rod 51, and the first stopper 52 is slidingly sleeved in the containing groove 503, and the first stopper 52 is in an expanded state after entering the middle shell 20.

[0075] In the above scheme, the first stopper 52 includes a plurality of stop pieces 521, the stop pieces 521 are elastic pieces, and a deformation groove 522 is arranged between adjacent two stop pieces 521, when the first stopper 52 enters the middle shell 20, the first stopper 52 slides along the containing groove 503, the deformation groove 522 becomes smaller, and the stop pieces 521 are contracted in the containing groove 503, so that the first stopper 52 is in a contracted state, and the first stopper 52 can be smoothly entered into the middle shell 20 together with the first slide rod 51. After the first stopper 52 enters the middle shell 20, the stop pieces 521 are ejected from the containing groove 503, so that the first stopper 52 is in an expanded state, at this time, the first stopper 52 can keep the first slide rod 51 in the middle shell 20, and the first slide rod 51 automatically slides out after being inserted into the middle shell 20.

[0076] In some optional embodiments, the length L5 of the containing groove 503 is greater than the length L6 of the first stopper 52, so that the first stopper 52 can be completely contracted in the containing groove 503 when following the first slide rod 51 to enter the middle shell 20, the smooth installation of the first slide rod 51 is ensured, and problems such as scratching and breaking of the first stopper 52 are avoided.

[0077] According to some optional embodiments, a plurality of grooves 412 are arranged on the outer wall of the clamping portion 41 in the axial direction of the cable clamp 40, i.e. the x direction, and a smooth surface 413 is defined between any two adjacent grooves 412. The provision of the smooth surface 413 can avoid scratching the inner wall of the middle shell 20 and is not easy to break, and a first heat dissipation channel 414 is formed between the first abutting positions of the two adjacent grooves 412.

[0078] In the above scheme, when the feeder is inserted into the clamping portion 41, the feeder can abut against the inner walls of the plurality of grooves 412, thereby increasing the contact area between the clamping portion 41 and the feeder and ensuring the stable connection between the feeder and the cable clamp 40. Meanwhile, the first heat dissipation channel 414 is formed between the first abutting positions of the two adjacent grooves 412, such as the annular first heat dissipation channel 414 formed between the first abutting position P and the first abutting position N of the two adjacent grooves 412. The cable clamp 40 is usually made of copper material, and when the outer conductor of the feeder is made of aluminum material, heat will be generated at the contact position of the copper material and the aluminum material after a long time of use. The first heat dissipation channel 414 can timely dissipate the heat, thereby reducing the heat generation between the two materials and ensuring the normal connection between the feeder and the connector and prolonging the service life.

[0079] According to some optional embodiments, the groove 412 includes a plurality of sub-grooves 4121, and the second abutting positions of the two adjacent sub-grooves 4121 are smoothly connected. The second heat dissipation channel 415 is formed between the second abutting positions of the two adjacent sub-grooves 4121. When the feeder is inserted into the clamping portion 41, the feeder can abut against the inner walls of the plurality of sub-grooves 4121, thereby increasing the contact area between the clamping portion 41 and the feeder and ensuring the stable connection between the feeder and the cable clamp 40. The second heat dissipation channel 415 is formed between the abutting positions of the two adjacent sub-grooves 4121, such as the second heat dissipation channel 415 formed between the second abutting position M and the second abutting position S of the two adjacent sub-grooves 4121. The second heat dissipation channel 415 can timely dissipate the heat generated by the feeder and the cable clamp 40, thereby ensuring the normal operation of the connector.

[0080] In some optional embodiments, the diameter of the groove on the clamping portion 41 is smaller than the outer diameter of the outer conductor of the feeder, which can ensure that the clamping portion 41 can effectively clamp the outer conductor of the feeder and ensure the transmission of signals.
