A coaxial cable connection device according to an embodiment of the present invention will be described with reference to fig. 1 to 5.
Fig. 2 is a schematic structural diagram of the coaxial cable connection device provided by the present invention, and fig. 3 is an exploded view of the coaxial cable connection device provided by the present invention. The coaxial cable connecting device includes a welding block including a welding block 21 and a dielectric block 22. The first groove 211 is opened in the welding block 21, the dielectric block 22 is installed in the first groove 211, the second groove 221 is opened in the dielectric block 22, and the opening directions of the first groove 211 and the second groove 221 are the same. The welding block is provided with a through hole 23 penetrating through the welding block 21 and the dielectric block 22, and the through hole 23 is communicated with the second groove 221. The solder bump 21 is made of a conductive material, such as a zinc alloy material, and is used to connect the shielding layers 13 of the two coaxial cables 1. The dielectric block 22 is made of an insulating material, such as insulating plastic. There are various ways for mounting the dielectric block 22 in the first groove 211, for example, the dielectric block 22 is fixed to the first groove 211 in a clamping manner; alternatively, the dielectric block 22 is fixed to the first recess 211 by interference fit. Further, after the dielectric block 22 is mounted in the first recess 211, the upper surface thereof is flush with the upper surface of the solder block 21.
When the coaxial cable is used, the outer skin layer 14, the shielding layer 13, the insulating layer 12 and the core conductor 11 need to be stripped from two coaxial cables 1 to be connected from outside to inside, and the stripping length of each layer is determined according to the sizes of the welding block 21 and the medium block 21 in the welding block. The two coaxial cables 1 are inserted from both ends of the through hole 23 of the solder block, respectively, so that the core wire conductors 11 of the two coaxial cables 1 each reach into the second groove 221 inside the dielectric block 22, and the shield layer 13 is located outside the dielectric block 22 and near the solder block 21. Then, conducting welding, namely, on one hand, conducting welding flux is piled and filled in the second groove 221 to weld the core wire conductors 11 of the two coaxial cables 1 together, so that the two core wire conductors 11 are electrically connected; on the other hand, the shield layer 13 of the coaxial cable 1 is soldered to the solder bump 21, thereby forming a shield layer around the soldered portion of the core conductor 11.
In the coaxial cable connecting device provided by the embodiment of the invention, the dielectric block 22 and the welding block 21 are arranged, the core conductor 11 is welded in the dielectric block 22, the shielding layer 13 is welded outside the dielectric block 22, and the core conductor 11 and the shielding layer 13 of two coaxial cables 1 can be correspondingly connected together. Since the dielectric block 22 is an insulator and the welding block 21 is a conductor, a signal shielding structure can be formed at the welded core conductor 11, and electromagnetic interference received at the welded portion can be reduced. In addition, since the welding positions of the core wire conductors 11 of the two coaxial cables 1 are located in the grooves of the dielectric block 22, the welding block can also prevent the welding positions from being affected by excessive stress, so that the reliability of the electrical connection of the two coaxial cables 1 is not affected. Therefore, the coaxial cable connection device provided by the embodiment realizes effective connection of the coaxial cable, speed and stability of signal transmission and improvement of reliability of electrical connection.
As shown in fig. 2 and 3, the through-holes 23 penetrating the solder block form first through-holes 212 on both sides of the solder block 21, respectively, and form second through-holes 222 on both sides of the dielectric block 22, respectively. When the dielectric block 22 is mounted in the first recess 211, the first through hole 212 and the second through hole 222 are communicated with each other. When the coaxial cable 1 is inserted into the through hole 23, the shield layer 13 cannot enter the second groove 221 to avoid the core conductor 11 and the shield layer 13 from being conducted by solder.
Therefore, in order to improve the positioning rapidity and accuracy when the coaxial cable 1 is inserted into the through hole 23, in the embodiment of the present invention, the second through hole 222 of the dielectric block 22 is a counter sunk hole, the small diameter section of the second through hole 222 is used for inserting the core conductor 11, and the step between the large diameter section and the small diameter section of the second through hole 222 is used for limiting the insulating layer 12, so as to prevent the insulating layer 12 from entering the second groove 221. The diameter of the small-diameter section is matched with the outer diameter of the core wire conductor 11, the diameter of the large-diameter section is matched with the outer diameter of the insulating layer 12, so that the medium block 22 can better coat and support the core wire conductor 11 and the insulating layer 12, and the risk that the core wire conductor 11 is broken during welding operation is reduced.
Further, the first through hole 212 of the solder bump 21 is also a countersunk hole, and the diameter of the small diameter section of the first through hole 212 is the same as that of the large diameter section of the second through hole 222, and is also used for covering the insulating layer 12. The diameter of the large diameter section of the first through hole 212 matches the outer diameter of the shielding layer 13 to form a better covering and supporting for the shielding layer 13. The first through hole 212 and the second through hole 222 are set as counter sunk holes, so that the insulating layer 12 and the shielding layer 13 stripped from the coaxial cable 1 to be welded are limited and coated and supported, and the reliability of mechanical connection of the coaxial cable can be improved.
Further, a tin guiding slope 214 is arranged at the first through hole 212 of the welding block 21. The solder guiding slope 214 is a tapered surface that surrounds the first through hole 212 on three sides or circumferentially, and the solder can flow between the soldering block 21 and the coaxial cable 1 to be soldered easily by the solder guiding slope 214 when the soldering block 21 and the shielding layer 13 are soldered.
The coaxial cable connection device provided by the embodiment of the invention further comprises a conductive sheet 3, and the conductive sheet 3 is installed in the second groove 221. The conductive sheet 3 is made of a material having high conductivity, such as copper, and is advantageous for reducing the loss of current flowing through the welding portion in the core conductor 11 of the coaxial cable 1. Specifically, the conductive plate 3 contacts with the bottom of the second groove 221, and the bottom of the second through hole 222 is flush with the upper surface of the conductive plate 3, so that when the core conductor 11 of the coaxial cable 1 is inserted into the through hole 23, the core conductor 11 is just located on the conductive plate 3 and contacts with the conductive plate.
The shape of the conductive sheet 3 may be various. For example, as shown in fig. 3, the conductive sheet 3 has a C-shaped structure, and the C-shaped structure is mounted in the second groove 221 with the opening facing upward to increase the contact area between the solder and the conductive sheet 3. For another example, the conductive sheet 3 has a structure in which a semicircular groove is formed on the upper surface thereof, and the core conductor 11 is fitted into the semicircular groove when inserted into the second groove 221, so as to increase the contact area between the core conductor 11 and the conductive sheet 3. The conductive plate 3 is in interference fit with the second groove 221.
When there are a plurality of parallel coaxial cables 1 to be connected, the welding blocks in the above embodiment are connected to each coaxial cable 1 in a one-to-one correspondence, so that there is a case where contact collision occurs between the welding blocks of adjacent paths, and since the welding block 21 is made of a conductive material, there is a risk that the parallel coaxial cables 1 are short-circuited. Therefore, the coaxial cable connection device provided by the embodiment of the invention further comprises a connecting seat 4 for installing the welding block. The connecting socket 4 is configured with stoppers 41 at both sides parallel to the axial direction of the through-hole 23, and the welding block 21 is installed between the stoppers 41, and the connecting socket 4 is made of an insulating material, such as insulating plastic. The stop 41 forms a barrier between the welding blocks 21 of two adjacent welding blocks to avoid short circuits when coming into contact with the welding blocks of other parallel coaxial cables 1.
The connection mode of the welding block 21 and the connection seat 4 can be various, for example, the welding block 21 and the connection seat 4 are welded and fixed; or the welding block 21 is fixedly connected with the connecting seat 4 through a bolt; or, the welding block 21 is clamped with the connecting seat 4, the welding block 21 is provided with a clamping tongue 213, and the connecting seat 4 is provided with a bayonet 42 matched with the clamping tongue 213. Specifically, as shown in fig. 3, the bayonets 42 are disposed on the stoppers 41 on both sides of the connecting seat 4, and the welding block 21 is clamped to the connecting seat 4 by pressing, which is convenient and fast.
Further, a pair of fixing portions 43 are formed on both sides of the connecting socket 4 extending along the axial direction of the through hole 23 for fixing the coaxial cables at both ends respectively. Specifically, the fixing portion 43 is used to fix the outer sheath layer 14 of the two-end coaxial cable 1. Before welding the coaxial cable 1, the coaxial cable 1 positioned on two sides of the welding block is fixed, so that the core wire conductor 11 is prevented from being separated, the risk of breaking the cable in the welding process is reduced, the operation difficulty of the welding process is reduced, the number of production operators is reduced, and the production cost is reduced.
Wherein, fixed part 43 is the ring groove structure, inserts coaxial cable 1 through-hole 23 location back, is about to the cable and impresses in the ring groove, very big convenience subsequent welding operation. The ring-shaped clamping groove can be in various forms, for example, the ring-shaped clamping groove is in a ring-shaped sheet structure extending along the axial direction of the through hole 23; alternatively, as shown in fig. 3, the ring-shaped clamping groove is a collar provided with an opening.

An automatic wire stripping machine can be adopted for wire shifting. The peeling length of the insulating layer 12 and the shielding layer 13 is determined by the thickness of the dielectric block 22 and the solder block 21 in the solder block. When the second through hole 222 of the dielectric block 22 and the first through hole 212 of the solder block 21 are countertop holes, the peeling length of the insulating layer 12 and the shielding layer 13 is determined according to the size of the two countertop holes.
