Description
The utility model is relevant a kind of coaxial cable welding point, and the signal that particularly is applied to high-frequency circuit and microwave circuit connects, and can reduce the discontinuous interface in the transmission.
Coaxial cable (Coaxial cable) is used in the transmission of signal widely, signal can be transferred to end in addition by coaxial cable; Its standard coaxial cable is constituted by signal line, insulating barrier, earth connection and insulated hull from inside to outside in regular turn, and signal end and earth terminal that signal line and earth connection are connected to reception place respectively can form the loop, and causes short circuit by the obstruct of insulating barrier is unlikely.
Coaxial cable applications signal transmission of (signal as distributor and receiver transmits) between two objects at present is as connected mode with the male and female joint, wherein the circuit board of two links is provided with a female joint respectively, and expose signal line and earth connection after the insulated hull of coaxial cable two ends divested, be placed on two ends of coaxial cable with male joint, the male joint of coaxial cable two ends is engaged to the female joint of two links in the mode that is spirally connected and forms and is electrically connected, therefore can tear group male and female joint according to need open, and connect or separate signal; Each joint is a transmission interface (signal is discontinuous interface), that is the transmission quality that connects face all can influence the quality of transmission, and many more transmission interfaces form many more discontinuous interfaces, can be influential to transmission quality.
Above-mentioned example with coaxial cable connection signal is meant to be applied in two different objects (to can be described as outside the connection); The mode that another kind of coaxial cable connects signal is that the signal transmission of two circuit boards in an object (can be described as inner the connection, as antenna), so with the inner ways of connecting of coaxial cable if adopt as during the mode of above-mentioned male and female joint, comparatively consuming time and cost is higher, and most discontinuous interfaces is more huge to the influence of signal transmission quality;
In order to solve with the inner problem that connects of coaxial cable, then can adopt direct welding manner, that is be to expose signal line and earth connection after insulated hull with coaxial cable is divested, directly signal line and earth connection are welded on the circuit board, the discontinuous interface that so can solve on business, female joint caused, but when the earth connection of welding coaxial cable, the high temperature during welding makes the insulating barrier of coaxial cable softening easily, and causes earth connection to contact and short circuit with signal line; Or when directly welding, position by the visual aligning welding of operator, if the signal end on the signal line that misoperation is as easy as rolling off a log to make coaxial cable and the circuit board can't parallel driving fit, in the connection of high frequency and microwave circuit, influence very big to quality and the frequency drift that transmits.
Main purpose of the present utility model promptly is to be to provide a kind of to reduce the discontinuous interface in the transmission and guarantee that signal transmits the welding point of the coaxial cable of quality, it has comprised that one can overlap as for the coaxial cable sleeve pipe, be extended with a weld part at the sleeve pipe front end, sleeve pipe directly is placed on the earth connection that coaxial cable can envelope coaxial cable imposes weld job, only has a transmission interface between two circuit boards in an object, and the part of earth connection is to be welded on the circuit board with weld part, do not consider earth connection and expose and touch signal line and produce short circuit, thereby can obtain preferable signal and transmit quality;
Another purpose of the present utility model promptly is that a kind of welding point that can quick affixed coaxial cable is being provided, by being configured on the coaxial cable of welding point, the signal line of weld part and coaxial cable has a gap and forms a fork, gap between the signal line of grounding parts and coaxial cable just is the thickness of circuit board, coaxial cable is inserted on the circuit board, directly weld the signal line of coaxial cable and the weld part of welding point, can finish affixed operation, and weld part can be used as the usefulness of fixing required welding position, the signal of the signal line of coaxial cable and circuit board is held capable driving fit level with both hands when guaranteeing to weld, this transmits for the signal on high frequency and the microwave circuit, also can guarantee the quality that signal transmits.
For making the purpose of this utility model, shape facility and function thereof there are further understanding, cooperate diagram to be described in detail as follows now, wherein:
Fig. 1 is structure chart of the present utility model.
Fig. 2 is embodiment generalized section of the present utility model.
According to the disclosed coaxial cable welding point of the utility model is the welding fixed operation that is applied between coaxial cable and circuit board, its standard coaxial cable 20 is constituted (as shown in Figure 2) by signal line 201, insulating barrier 202, earth connection 203 and insulation sheath 204 from inside to outside in regular turn, and the link of coaxial cable 20 must divest insulation sheath 204 in advance and exposes earth connection 203 before weld job, again one section earth connection 203 and insulating barrier 202 divested in addition, expose one section signal line 201, so that follow-up operation.
See also shown in Figure 1ly, this welding point 10 mainly is the sleeve pipe 101 for a hollow, is extended with a weld part 102 at sleeve pipe 101 front ends, and this welding point 10 must be to be conductor, and material can be red metal; Its middle sleeve 101 can overlap as for being electrically connected on the earth connection 203 of coaxial cable 20 and with earth connection 203, and weld part 102 is to be extended forward by sleeve pipe 101 front end root edges, and weld part 102 must be and the central axis of sleeve pipe 101 between have a gap.
Continuous see also shown in Figure 2, when desire is welded coaxial cable 20 with circuit board 30, earlier welding point 10 is placed on the earth connection 203 of coaxial cable 20, and the signal line 201 of coaxial cable 20 will be stretched out by sleeve pipe 101 front ends, and keep a gap d with the weld part 102 of welding point 10, and make weld part 102 and 201 of signal line form a fork, and this gap d is the thickness that is slightly larger than circuit board 30; On high frequency or microwave circuit boards 30, its signal end and earth terminal are respectively two of circuit board 30, therefore after coaxial cable 20 has been nested with welding point 10, weld part 102 and signal line 201 formed forks directly can be inserted on the circuit board 30, signal line 201 is corresponding to the signal end of circuit board 30 respectively, weld part 102 is corresponding to the earth terminal of circuit board 30, when the coaxial cable 20 that therefore will be with welding point 10 is inserted on the circuit board 30, weld part 102 is as the usefulness of fixed position, then can impose weld job is fixed, by separating of welding point 10, under the weld job of high temperature, be difficult for making the insulating barrier 202 softening isolated relations that keep earth connection 203 and signal line 201 of coaxial cable 20, comparatively quick on weld job, and can be fixed on the circuit board 30 by weld part 102, the signal line 201 of coaxial cable 20 can be accurately in alignment with the signal end on the circuit board 30, to guarantee the parallel driving fit of the two.
Learn that by above explanation the utility model is that the joint that provides coaxial cable to connect with welding manner is provided, and utilizes the utility model to reach:
One, transmits at the signal of two circuit boards, can reduce discontinuous interface, except that the transmission quality that can guarantee signal, also can reduce cost.
