Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the invention and therefore show only the structures which are relevant to the invention.
In the prior art, the connection manner between the connector and the coaxial cable is generally divided into two types, namely an elastic connection manner and a soldering connection manner;
As shown in fig. 1-2, in the technical scheme of adopting an elastic connection mode between a connector and a coaxial cable in the prior art, in the technical scheme, the connector 1a comprises a handheld part 1a-3 and an inner conductor 1a-1 positioned at the front end of the handheld part, an elastic connection section 1a-2 is radially arranged in a protruding mode in the middle of the axial direction of the inner conductor 1a-1, when the connector 1a is inserted into the coaxial cable 1b to realize interconnection, the elastic connection section 1a-2 radially arranged in a protruding mode protrudes outwards to be clamped on the inner wall of an inner core hole 1b-1 of a cable inner core 1b-2 of the coaxial cable 1b, so that good connection between the connector 1a and the coaxial cable 1b is realized, and due to the adoption of elastic contact, the outer diameter of the elastic connection section 1a-2 is larger than the inner wall size of the inner core hole 1b-1, good connection between the connector 1a and the coaxial cable 1b is realized through elastic deformation.
The disadvantage of this connection is: since the elastic connection section 1a-2 belongs to the lobe-shaped protruding part of the elastic groove, the elastic connection section 1a-2 can lead to the rapid decrease of the contact performance after the material is fatigued with the duration of the use time and the number of the insertion and extraction times, thereby affecting the rapid decrease of the connection performance and the power transmission stability.
As shown in fig. 3-4, in the technical scheme of adopting a soldering connection mode between a connector and a coaxial cable in the prior art, in the technical scheme, the connector 1c comprises a handheld part 1c-1 and an inner conductor 1c-2 positioned at the front end of the handheld part, when the connector 1c is inserted into the coaxial cable 1d to realize interconnection, tin wire filling and auxiliary soldering flux are adopted between the periphery of the inner conductor 1c-2 and an inner core hole 1d-1 of a cable inner core 1d-2 of the coaxial cable 1d, and the temperature between the inner conductor of the connector and the cable inner core reaches the melting point (about 220-250 ℃) of tin wires through welding and high-temperature heating, so that the tin wires are melted and filled between the cable inner core and the inner conductor of the connector, and tin is solidified after heating is finished, and the weldability of tin and copper materials is utilized to realize connection between the tin wire and the inner conductor.
The disadvantage of this connection is: the solid tin can melt and weld two adjacent copper surface metals, and in the use environment, the conductor is easy to generate heat in a long-term high-power and high-current working state, and when heat is accumulated to the melting point of tin, the tin layer between the cable inner core and the connector inner conductor is inevitably melted, so that the serious consequence of the connection failure of the connector and the cable inner core is easy to cause.
Therefore, aiming at the defects, the invention provides the following technical scheme to solve the defects and problems of the connection mode in the current industry.
As shown in fig. 5 to 7, an inner conductor connecting device using a screw connection is composed of a connector 1 and a coaxial cable 2 which are mutually inserted, the connector 1 being inserted into the inside of the coaxial cable 2; wherein,
The connector 1 comprises a signal end 1-1, a rotating part 1-2, a connecting section 1-3, a stop plate 1-4, a thread arrangement section 1-6 and an inner conductor 1-5 which are sequentially connected from left to right; the rotating part 1-2 is arranged on the right side of the signal end 1-1, the radial dimension of the rotating part 1-2 is larger than that of the signal end 1-1, the connecting section 1-3 is positioned between the rotating part 1-2 and the stop plate 1-4 to connect the rotating part 1-2 and the stop plate 1-4, the radial dimension of the stop plate 1-4 is larger than that of the left connecting section 1-3 and the right thread arrangement section 1-6, and the radial dimension of the stop plate 1-4 is abutted with the left end face of the coaxial cable 2 to realize the axial positioning of the connector 1 and the coaxial cable 2, and the thread arrangement section 1-6 and the inner conductor 1-5 are positioned inside the coaxial cable 2;
The coaxial cable 2 comprises a cable shell 2-1 and a cable clamping part 2-2 fixedly arranged at the right end of the cable shell 2-1, a cable inner core 2-3 is fixedly arranged in the coaxial cable 2, and an inner core hole 2-4 is formed in the radial inner part of the cable inner core 2-3; the thread arrangement section 1-6 and the inner conductor 1-5 are positioned in the inner core hole 2-4 to realize the connection of the connector 1 and the coaxial cable 2;
The thread arranging section 1-6 is fixedly provided with thread sections 1-7 in a protruding mode at equal intervals, the thread sections 1-7 comprise a plurality of circles of cutting threads 1-71 which are arranged along the axial direction of the thread arranging section 1-6, the outer diameter of the cutting threads 1-71 is larger than the inner diameter of the inner core hole 2-4, the inner diameter of the cutting threads 1-71 is smaller than the inner diameter of the inner core hole 2-4, and a plurality of chip containing grooves 1-72 are formed in the circumferential direction of the thread sections 1-7 at equal intervals. Preferably, the number of turns of the cutting thread 1-71 arranged along the axial direction of the thread arrangement section 1-6 should be at least 8, and 4 chip receiving grooves 1-72 are also provided at equal intervals in the circumferential direction of the thread section 1-7.
Specifically, the chip receiving groove 1-72 extends in the axial direction from the thread arrangement section 1-6 to the inner conductor 1-5, so that it is ensured that impurities, chips and particles generated when the cutting thread 1-71 is closely fixed on the inner wall of the cable core 2-3 by thread compaction are easily discharged through the chip receiving groove 1-72 with a sufficient axial extension.
Specifically, the hardness of the cutting thread 1-71 is greater than the hardness of the inner wall of the cable core 2-3. Specifically, the cutting thread teeth 1-71 are formed by machining a phosphor copper alloy material, so that the screw thread compaction and close fixation of the cutting thread teeth on the inner wall of the cable inner core 2-3 are realized with high hardness.
Specifically, the outer diameter of the stop plate 1-4 is equal to the outer diameter of the cable core 2-3, so that the axial stop of the connector 1 is realized through the stop plate 1-4, and the axial position of the connector 1 relative to the coaxial cable 2 is ensured to be fixed.
Specifically, a clearance exists between the outer diameter of the screw arrangement section 1-6 and the inner wall of the inner core hole 2-4, so that scraps and impurities generated at the time of screw connection are conveniently discharged through the scraps-containing grooves 1-72.
Specifically, the periphery of the cable housing 2-1 is provided with a wavy structure comprising an arc protruding point 2-11 and an arc inner groove 2-12, the inner wall of the cable clamping part 2-2 is provided with a wavy structure matched with the arc protruding point 2-11 and the arc inner groove 2-12 and is well matched with the periphery of the cable housing 2-1, and the wavy structure increases the contact area with hands on one hand, so that the outer operator can conveniently plug the connector 1 in the coaxial cable 2, and on the other hand, the contact area with the cable clamping part 2-2 is increased through the wavy structure, and the installation stability of the cable clamping part 2-2 is ensured.
Specifically, the radial dimension of the circular arc protruding point 2-11 located at the leftmost end of the cable housing 2-1 is maximized, so that the axial positioning of the connector 1 with respect to the coaxial cable 2 when connected with the coaxial cable 2 is achieved by the larger radial dimension when the connector 1 is inserted into the inside of the coaxial cable 2 and the connector 1 is pulled out from the inside of the coaxial cable 2.
Specifically, the rotating portion 1-2 is provided with a rotation protrusion 1-21 protruding in the radial direction for facilitating rotation, thereby facilitating the actual operation of an external operator by rotating the protrusion 1-21 when the connector 1 is inserted into the coaxial cable 2 and when the connector 1 is pulled out from the inside of the coaxial cable 2.
Specifically, the axial length of the thread segments 1-7 is smaller than the axial length of the thread arrangement segments 1-6, so that when the connector 1 is inserted into the coaxial cable 2 and the connector 1 is pulled out from the inside of the coaxial cable 2, there is a buffer zone in the process of screwing, thereby ensuring firm connection between the cutting thread teeth and the inner wall of the inner core hole, and at the same time, the buffer zone is convenient for chips and impurities existing in the screwing to be discharged through the chip accommodating grooves 1-72.
During specific connection, one end of the connector 1, which is close to the inner conductor 1-5, is provided with the cutting thread 1-71, and since the outer diameter of the cutting thread 1-71 is larger than the inner diameter of the inner core hole 2-4, the inner diameter of the cutting thread 1-71 is smaller than the inner diameter of the inner core hole 2-4, at the moment, an external worker grabs the rotating part 1-2 to rotate the connector 1, and inserts one end of the inner conductor 1-5 of the connector into the inner part of the coaxial cable 2 through the cutting thread 1-71, so that more than a plurality of circles of spiral circumference contact between the connector 1 and the cable inner core 2-3 of the coaxial cable 2 are formed, and the hardness of the cutting thread 1-71 is larger than the hardness of the inner wall of the inner core hole 2-4, so that firm pressure bonding is formed between the cutting thread 1-71 and the inner core hole 2-4, and the service life of the connector 1 and the coaxial cable 2 is prolonged, and the cable inner core 2-3 is extruded and wrapped on the surface of the cutting thread 1-71, so that the connector and the connector are fully contacted, and the good conductive heat energy is obtained, and the working capacity is reduced.
