Abstract
The invention discloses a phase-adjustable coaxial connector. The phase-adjustable coaxial connector comprises a shell. A thread sleeve is arranged on the shell. A head shell body is arranged between the thread sleeve and the shell. A groove is formed in the portion, making contact with the head shell body, of the shell. A shielding reed is arranged in the groove. A cable is arranged in the shell. A core wire of the cable is connected with a pin. The pin is connected with an insertion hole. The phase-adjustable coaxial connector has the advantages that stability of the voltage standing wave ratio and insertion losses is ensured before and after phase adjustment is conducted; the structure is compact so that the length of the connector can be small and production cost of products can be directly reduced.
Description
Technical field
The present invention relates to electric connector, be specifically related to a kind of adjustable phase coaxial connector.
Background technology
In the phase system of phased array radar and electronic countermeasures, require cable/connector cable assembly to there is accurate electrical length.In some cases, require the phase stability of a group of cable/connector cable assembly (>=2 with assembly) at ± 1 °, even higher.Under certain frequency, by calculating, the mechanical length of this group cable/cable assembly differs 0.1-0.3 millimeter, in this case, the manufacturing firm of cable/connector cable assembly will cut cable, install, tests in the time installing, debug, and has many external factors to disturb, so need to again and again many times just can reach requirement owing to cutting and installing at every turn, if and misoperation, can scrap because cut the excessive cable that causes.For the phase matched of many assemblies, this problem is more outstanding.
At present, the way addressing this problem has: one, adopt high-end rolling off the production line-wire stripping equipment, and very good of the length consistency that makes cable, but because cable itself exists material inhomogeneities, it is not fine causing effect; Two, adopt phase place phase selection, that is: first roughly produce a collection ofly, by test, select one group of phase place consistent, qualified cable/connector cable assembly combines; The method need to have good market prerequisite; Three, adopt the adjustable method of phase place, that is: regulate by the electrical length to connector, make the phase place of cable/connector cable assembly on the same group meet the requirements of scope.But for the product of requirement that meets high standing-wave ratio and phase place simultaneously, the method requires debugging repeatedly and design compensation just can reach requirement.
Current phase place adjustable connector scheme, adopts the contact head of splitting slot type to connect, and this product can solve the phase matched of part small-sized coaxial connector product.On the one hand, the internal-and external diameter of small-sized coaxial connector product is less, and the gap that relatively moving between each part caused is less, and easily by conventional compensation way, voltage standing wave ratio is adjusted.But can exist voltage standing wave ratio to adjust difficulty for large joint such as such as TNC type, N-type etc.; ; On the other hand, this kind of method causes connector length longer, and impact is installed, and increases the manufacturing cost of product.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and this invention solves the phase adjusted problem of cable/connector cable assembly of large joint such as such as TNC type, N-type etc.
The present invention is by the following technical solutions:
A kind of adjustable phase coaxial connector, comprise housing, described housing is provided with swivel nut, between described swivel nut and described housing, be provided with casing, the position that described housing contacts with casing at it is provided with groove, in described groove, is provided with shielding finger, in described housing, is provided with cable, on the heart yearn of described cable, be connected with contact pin, on described contact pin, be connected with jack.
By being set, shielding finger completes the connection of connector outer conductor (being casing and housing), and firmly, reliable, by being set, shielding finger makes product structure optimization, in the time that connector regulates length, in keeping connector inner wire (being contact pin and jack) to be connected with outer conductor (being casing and housing), capacitive reactance and induction reactance that inner wire (being contact pin and jack) and outer conductor (being casing and housing) are produced are all not enough to affect voltage standing wave ratio, when phase place is met the demands, voltage standing wave ratio and Insertion Loss all meet the requirements.
Further technical scheme is, described swivel nut is flexibly connected with housing by collar.
Realize being flexibly connected of swivel nut and housing by collar, the one side contacting with swivel nut at it on casing is provided with the screw thread of P=0.5, the one side contacting with casing at it on swivel nut is also provided with P=0.5 screw thread, so just realize swivel nut rotation, in the time of rotation swivel nut, housing will move, thereby drive cable moving, cable moving time will make contact pin produce relative displacement, displacement can reach 2-3mm, again in this distance range, inner wire (being that contact pin and jack are realized conducting) and outer conductor (being that casing and housing are realized conducting), when displacement, voltage standing wave ratio is in control range, all expire group while requiring when testing on the same group cable/connector cable assembly, just can be by the first nut and the second nut screwing clamping, swivel nut and casing are fixed, realize the connection of connector.
Further technical scheme is, described shielding finger is that arc and described shielding finger top contact with casing, and described shielding finger bottom contacts with housing.
By reed is set, because having elasticity, shielding finger just can ensure that housing normally contacts with casing.
Further technical scheme is, described cable is connected with housing by the mode of welding.
Further technical scheme is, the heart yearn of described cable is connected with contact pin by the mode of welding.
Further technical scheme is, described casing surface is provided with the first nut, and described surface of shell is provided with the second nut.
Just can realize swivel nut and casing are fixed by the first nut and the second nut are set.
Compared with prior art, the invention has the beneficial effects as follows:
1,, before and after phase adjusted, ensured the stability of voltage standing wave ratio and Insertion Loss;
2, compact conformation of the present invention, makes connector length shorter, and can directly reduce the production cost of product.
