Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
as wireless communication technology continues to evolve, the reduction in size of communication equipment means space savings, weight savings, and more margin for other system designs, and the traditional cumbersome cable assembly connections are being replaced by simple, compact, reliable "board-to-board" rf coaxial connector connections. The application of the board-to-board radio frequency coaxial connector in the wireless system module interconnection is more and more extensive: for example, in the conventional smart antenna, 9 sets of N-type radio frequency connector cable assemblies are used for connection, and the radio frequency coaxial connector can connect the radio frequency cable assemblies to the three-sector electrically-tunable smart antenna through 3 sets of cable assemblies, and even can reduce the original requirement of 27 sets of N-type radio frequency connector cable assemblies to 6 sets of radio frequency coaxial connectors; meanwhile, the TD ultra-wideband intelligent antenna can be reduced from the original connection mode of needing 9 sets of cable assemblies to the connection mode of 2 sets of radio frequency coaxial connectors. Therefore, the radio frequency coaxial connector and the radio frequency coaxial connector assembly have strong advantages in the aspects of construction convenience, reliability, economy and attractiveness. The series products are used as solutions for modularization and serialization of two radio frequency ports of a TD antenna project, so that the operation process is simplified, and the products are more and more accepted by the market; more manufacturers are beginning to apply multi-channel connectors and their components.
In the related art, referring to fig. 1, a radio frequency coaxial connector product 100 includes: a first socket 101 having a first outer conductor 101a, a first inner conductor 101b, and a first insulator 101c disposed around the first inner conductor 101b between the first outer conductor 101a and the first inner conductor 101 b; a second socket 102 having a second outer conductor 102a, a second inner conductor 102b, and a second insulator 102c disposed around the second inner conductor 102b between the second outer conductor 102a and the second inner conductor 102 b; and an adaptor 103 having an adaptor outer conductor 103a, an adaptor inner conductor 103b, and an adaptor insulator 103c disposed between the adaptor outer conductor 103a and the adaptor inner conductor 103b, the adaptor insulator 103c being disposed around the adaptor inner conductor 103b in a length direction of the adaptor inner conductor 103b, and the adaptor insulator 103c having both ends facing the first insulator 101c and the second insulator 102c, respectively, wherein free ends of the first inner conductor 101b and the second inner conductor 102b are inserted into the adaptor inner conductor 103b to make electrical contact with the adaptor inner conductor 103b, respectively, and both ends of the adaptor outer conductor 103a are inserted into the first outer conductor 101a, the second outer conductor 102a, respectively, to make electrical contact with the first outer conductor 101a, the second outer conductor 102a, respectively, and wherein: both end portions of the adapter insulator 103c are formed with tapered recesses that increase in size toward the end portions; the sides of the first insulator 101c and the second insulator 102c facing the adapter insulator 103c are each formed as a tapered convex portion tapered toward the adapter 103 adapted to fit into the tapered concave portion.
The coaxial connector assembly 100 described above has the following drawbacks: because the connection mode of the two ends of the adaptor 103 and the first socket 101 and the second socket 102 only depends on the interaction of the tapered concave parts formed at the two ends of the adaptor insulator 103c and the tapered convex parts on the first insulator 101c and the second insulator 102c only by means of contact, the first inner conductor 101b and the second inner conductor 102b are respectively and electrically connected with the adaptor inner conductor 103b, and the connection mode of the first inner conductor 101b, the second inner conductor 102b and the adaptor inner conductor 103b is not tight and reliable; at the same time, because the amount of contact is small, the upper limit of the power that can be carried by the coaxial connector assembly 100 is low.
In view of the above problems, the present embodiment provides a radio frequency coaxial connector with reference to fig. 2-5, first please refer to a schematic structural diagram of the radio frequency coaxial connector shown in fig. 2:
the radio frequency coaxial connector 200 comprises a first connector 1, an intermediate connector 2 and a second connector 3. The intermediate connector 2 is disposed between the first connector 1 and the second connector 3, and is configured to receive the first connector 1 and the second connector 3, so as to realize physical connection and electrical connection between the first connector 1 and the second connector 3.
In the present embodiment, each of the first connector 1, the intermediate connector 2, and the second connector 3 includes an inner conductor and an outer conductor, respectively, and further includes a spacer for isolating the inner conductor from the outer conductor between the inner conductor and the outer conductor. 3 for 3 example 3, 3 referring 3 further 3 to 3 fig. 33 3, 3 fig. 33 3 shows 3 a 3 schematic 3 cross 3- 3 sectional 3 view 3 of 3 the 3 rf 3 coaxial 3 connector 3 200 3 along 3 line 3 a 3- 3 a 3' 3 of 3 fig. 32 3: 3
The first connector 1 includes, in order from outside to inside, a first outer conductor 11, a first separator 12, and a first inner conductor 13; the second connector 3 includes, in order from the outside to the inside, a second outer conductor 31, a second spacer 32, and a second inner conductor 33; the intermediate connector 2 includes, in order from the outside to the inside, an intermediate outer conductor 21, an intermediate spacer 22, and an intermediate inner conductor 23.
The intermediate connector 2 is received between the first connector 1 and the second connector 3, and both ends of the intermediate outer conductor 21 are electrically connected to the first outer conductor 11 and the second outer conductor 31, respectively; both ends of the intermediate inner conductor 23 are electrically connected to the first inner conductor 13 and the second inner conductor 33, respectively. The connection of the inner conductors between the first connector 1, the second connector 3 and the intermediate connector 2 will be described with reference to fig. 3:
the intermediate inner conductor 23 includes a conductive shaft 231 and contact terminals 232 respectively provided at both ends of the conductive shaft 231. The contact terminal 232 is used for connecting with the first inner conductor 13 and the second inner conductor 33, and the contact terminal mated with the first inner conductor 13 is referred to as a first contact terminal 232a, and the contact terminal mated with the second inner conductor 33 is referred to as a second contact terminal 232 b.
In the present embodiment, the end of the first inner conductor 13 connected to the intermediate inner conductor 23 is referred to as a "first connection end", and the end of the second inner conductor 33 connected to the intermediate inner conductor 23 is referred to as a "second connection end". One of the first connection end and the first contact terminal 232a is used as a first male plug, and the other is a hollow first female plug. It will be appreciated that the first male and female male members may be inserted into the first female insert to mate with the first female insert to effect an electrical connection between the intermediate inner conductor 23 and the first inner conductor 13. Because the inner split groove is axially formed on the port of the first inner male head in this embodiment, the first inner male head has a certain contractibility, in other words, the first inner male head is actually an elastic component. Therefore, after the first inner male plug is inserted into the first inner female plug, because the end of the first inner male plug tends to expand outwards, the first inner male plug and the first inner female plug can be tightly combined to form an interference fit, and the reliability of physical connection and electrical connection between the first inner conductor 13 and the middle inner conductor 23 is ensured.
Similarly, the second inner conductor 33 and the middle inner conductor 23 are connected and matched, and the second connection end on the second inner conductor 33 and one of the second contact terminals 232b are used as a second male plug, and the other is a hollow second female plug. It will be appreciated that the second male and female connector may be inserted into the second female connector for male and female mating therewith to effect electrical connection between the intermediate inner conductor 23 and the second inner conductor 13. Because the inner split groove is axially formed on the port of the second inner male head in this embodiment, the second inner male head has a certain contraction and expansion property, and the second inner male head is actually an elastic component. Therefore, after the second inner male plug is inserted into the second inner female plug, because the end of the second inner male plug tends to expand outwards, the second inner male plug and the second inner female plug can be tightly combined to form an interference fit, and the reliability of physical connection and electrical connection between the second inner conductor 33 and the middle inner conductor 23 is ensured.
In the present embodiment, "hollow" is required, and the first connection end, the first contact terminal 232a, the second connection end, and the second contact terminal 232b are required to be hollow, and other substances other than air are not necessarily present, and the description will be given by taking the example where the first contact terminal 232a is hollow, but only that the first contact terminal 232a is not a solid structure made of one material, and for example, an insulating material may be filled in the hollow first contact terminal 232 a.
In some examples of the present embodiment, the first inner conductor 13 may be used as a first male plug and the first contact terminal 23a may be used as a first female plug. In other examples of the present embodiment, the first inner conductor 13 serves as a first female plug and the first contact terminal 23a serves as a first male plug. Correspondingly, the second inner conductor 33 and the second contact terminal 232b are similar, in some examples, the second inner conductor 33 serves as a second male plug, and the second contact terminal 232b serves as a second female plug, while in other examples of the embodiment, the second contact terminal 232b serves as a second male plug, and the second inner conductor 33 serves as a second female plug.
In order to further increase the tightness of the contact between the middle inner conductor 23 and the first inner conductor 13 and the second inner conductor 33, in some examples of the present embodiment, the outer walls of the first inner male head and the second inner male head are further provided with outward protruding guide blocks, so that the positions of the first inner male head and the second inner male head, where the guide blocks are provided, have larger diameters relative to other positions. After the second inner male head is inserted into the second inner female plug, the second inner male head has a large expansion tendency, so that good contact between the second inner conductor and the middle inner conductor can be ensured.
In the rf coaxial connector 200 shown in fig. 2, the first contact terminal 232a and the second contact terminal 232b are respectively provided as a first male connector and a second male connector, so that the first contact terminal 232a and the second contact terminal 232b are respectively inserted into the first inner conductor 13 and the second inner conductor 33 when being respectively mated with the first inner conductor 13 and the second inner conductor 33. Referring to fig. 4, fig. 4 is a partially enlarged schematic view of a portion a in fig. 3: at the end of the first contact terminal 232a, an inner split groove 233 is opened in the axial direction, it being understood that there may be more than one inner split groove opened on one contact terminal.
Naturally, when the first contact terminal 232a and the second contact terminal 232b are respectively a first male-female head and a second male-female head, the guide block is disposed on the outer wall of the first contact terminal 232a and the second contact terminal 232 b. At the outer periphery of the first contact terminal 232a near the end, an outwardly projecting guide piece 234 is provided, the guide piece 234 being provided so that the diameter of the first contact terminal 232a is increased thereat. In some examples of the present embodiment, the side of the guide block 234 facing away from the conductive shaft is provided with a chamfer, which, due to the oblique orientation of the chamfer, better guides the first contact terminal 232a into the first connection end of the first inner conductor 13 when inserting the intermediate inner conductor 23 into the first inner conductor 13. The arrangement of the second contact terminals 232b is similar and will not be described again.
In some examples of this embodiment, the diameter on the first inner male is larger closer to the end of the first inner male, and the diameter on the second inner male is larger closer to the end of the second inner male. Continuing with the first contact terminal 232a as the first male-female connector: the diameter of the first inner male portion is larger at the end closer to the first inner male portion, that is, the diameter of the first contact terminal 232a becomes smaller and smaller as the first contact terminal gets closer to the conductive shaft 231, so the diameter of the end far from the conductive shaft 231 is larger than the diameter of the end of the first contact terminal 232a close to the conductive shaft 232 b. Therefore, when the contact terminal is matched with the first inner conductor 13 and the second inner conductor 33, the radial tolerance amount is higher, the installation and matching stability of each structure is better, the bearable power is higher, and the product performance is better.
In some examples of the present embodiment, the diameter of the two contact terminals is smaller than the diameter of the conductive shaft 231, that is, the contact terminals are thinner than the conductive shaft 231, so that a shoulder is formed between the conductive shaft 231 and the contact terminals, as shown in fig. 4, in the present embodiment, the shoulder between the conductive shaft 231 and the first contact terminal 232a is a first shoulder 235, and the shoulder between the conductive shaft and the second contact terminal 232b is a second shoulder (not shown).
In the rf coaxial connector 200 shown in fig. 2-4, after the first contact terminal 232a is connected to the first inner conductor 13, a margin groove 236 exists between the first inner conductor 13 and the first shoulder 235, that is, a certain distance exists between the first shoulder 235 and the first inner conductor 13, and the distance can be used for adaptive adjustment of the adaptive position of the conductive shaft 231 during swinging, that is, the conductive stability requirement during swinging of the conductive shaft 231 is satisfied. Correspondingly, a residual groove is also present between the second shoulder and the second inner conductor 33.
In the radio frequency coaxial connector provided by this embodiment, the inner split groove is formed on the contact terminal of the middle inner conductor, so that the end of the middle inner conductor is set as an elastic component with a contractibility, and when the contact terminal is matched with the first inner conductor and the second inner conductor, the contact terminal can be combined more tightly, and the stability and reliability of the electrical connection of the radio frequency coaxial connector are improved; meanwhile, the power which can be borne by the radio frequency coaxial connector can be improved.
Example two:
the present embodiment will be described with reference to fig. 2 to 4 for the connection among the outer conductors of the first connector 1, the intermediate connector 2 and the second connector 3:
it should be understood that the connection between the first outer conductor 11 and the middle outer conductor 21, and the connection between the second outer conductor 31 and the middle outer conductor 21 may also be made in a male and female manner. In order to distinguish the male plug and the female plug between the inner conductors, in the present embodiment, the male plug formed between the outer conductors is referred to as an "outer male plug", and the female plug is referred to as an "outer female plug". In an example of the present embodiment, the first end of the middle outer conductor 21 is a hollow structure, one of the first end of the middle outer conductor 21 and the first contact terminal 232a is a first male plug, and the other is a first female plug. The first outer male plug extends into the first outer female plug to form an electrical connection between the middle outer conductor and the first outer conductor. Similarly, one of the second end of the middle outer conductor 21 and the second outer conductor 31 is a second outer male plug, the other is a hollow second outer female plug, and the second outer male plug extends into the second outer female plug to form an electrical connection between the middle outer conductor and the second outer conductor.
Similarly, the "hollow" of the outer conductor does not require that something other than air be present inside the first end, the second end, the first outer conductor 11, or the second outer conductor 31 of the middle outer conductor 21, but rather indicates that the first end, the second end, the first outer conductor 11, or the second outer conductor 31 of the middle outer conductor 21 is not a solid structure composed of the same material. As is apparent from the figure, the first outer conductor 11 also includes a first separator 12 and a first inner conductor 13, and the intermediate outer conductor 21 also includes an intermediate separator 22 and an intermediate inner conductor 23. The second outer conductor 31 further includes a second separator 32 and a second inner conductor 33.
In some examples of the present embodiment, the first outer conductor 11 may be used as a first male plug, and the first end of the middle outer conductor 21 may be used as a first female plug. In other examples of the present embodiment, the first outer conductor 11 may be used as a first outer female plug, and the first end of the middle outer conductor 21 may be used as a first outer male plug. Correspondingly, there is a similarity between the second outer conductor 31 and the intermediate outer conductor 21: in some examples, the second outer conductor 31 serves as a second outer male plug, and the second end of the middle outer conductor 21 serves as a second outer female plug, while in other examples of the present embodiment, the second end of the middle outer conductor 21 serves as a second outer male plug, and the second outer conductor 31 serves as a second outer female plug.
