Description
Technical field
The present invention relates to wireless technical field of micro communication, the DIN type flange coupling connector that especially a kind of intermodulation improves.
Background technology
Common DIN type flange coupling connector is connected with the panel of microwave device through screw, has promptly accomplished mechanical connection, simultaneously also because contacting also to have accomplished and be electrically connected between flange and the panel.Under the situation that does not have the intermodulation requirement, such installation just can be satisfied the various machineries and the electric index request of system fully.
Flourish along with communication industry; Various radio frequency applications emerge in an endless stream; Country all is assigned corresponding use frequency range to every kind of application, and for example the frequency of utilization of GSM is 890MHz～960MHz, and the use frequency range of the every kind of application band frequency of also will being separated by; Otherwise will produce destructive phase mutual interference, frequency resource just becomes more and more in short supply like this.Wireless communication system is as one of them important use, in order in limited frequency range, to improve use capacity and service quality, this just require communication system efficiently, frequency of utilization resource reliably.Address this problem, what stand in the breach is exactly the intermodulation index request, and the intermodulation requirement has been arranged, and interference between signals will obtain good restraining, even two frequencies of utilization are very approaching.
The various devices that the high intermodulation of communication system just requires to form system have very high intermodulation index.For device the most basic in the communication system-DIN type connector, the intermodulation index just requires higher.What in the connector intermodulation is had the greatest impact is exactly contact, and as far as flange coupling connector, being exactly flange face contacts and applying fully with the tight of device panel surface.Because the flange face of DIN type flange coupling connector and the surface of device all are bigger surfaces; Be difficult in the machining process do their flatness very highly; It is not full the applying that the plane contact of such two injustice just causes their contact easily; Around the installing hole of more fearful is device panel is not the full contacts of 360 degree, can cause the intermodulation index to lose efficacy like this.
There is a lot of connector manufacturer on DIN type flange coupling connector flange face, to design an intermodulation contact ring that exceeds flange face now to reduce the contact area between flange and the panel.The contact ring area is little, and flatness just can be done highly, so both increases contact pressure and has increased contact reliability, has reduced the risk that can not contact entirely that the out-of-flatness owing to contact-making surface processing causes again.
For the contact pressure that increases between flange and the panel increases contact reliability; Reduce again simultaneously because the risk that can not contact entirely that the out-of-flatness that contact-making surface is processed causes, often on Flange Plane, can process the intermodulation contact ring of a projection in the design of connector.Though solved the problems referred to above like this, because the actual conditions of producing in batches often can not get ideal results.
Correct screw-driving mode should be uniformly, the carrying out of diagonal formula: earlier screw on power but do not tighten of one of them screw; Twisting cornerwise screw power of screwing on does not again tighten yet; Two other screw of then screwing on has in the same way been accomplished tightening of first round screw like this.Carry out second again with the order of the first round and take turns and tighten, this takes turns screw and only is screwed to half tight condition, and last third round is all tightened all screws.But in the production assembling process, the workman is a pursuit speed often, always earlier all tightens one of them screw during rigging screw, tightens next screw up to tightening all screws along a direction again.Like this, when all tightening first with second screw, two other screw position will stick up.When tightening these two screws that stick up, flange face will arch upward probably, cause the intermodulation contact ring can not be fine the applying panel of 360 degree, thereby cause the deterioration of intermodulation index.
Summary of the invention
The objective of the invention is: the DIN type flange coupling connector that provides a kind of intermodulation to improve, it is simple in structure, and reliable installation is simplified workman's on the production line operation, reduces workman's work difficulty, saves time, and enhances productivity; Be fit to field erected current conditions, and can guarantee the formedness of intermodulation index.
Technical scheme of the present invention is: the DIN type flange coupling connector that a kind of intermodulation improves, the centre of the flange face that said DIN type flange coupling connector contacts with panel are provided with a circle intermodulation contact ring; The screw hole position of DIN type flange coupling connector exceeds flange face and constitutes the pad pin, but the height of pad pin is not higher than the height of intermodulation contact ring.
Further explain in the face of technique scheme down:
Said pad pin evenly distributes, and the interior profile of pad pin is a circular arc, and the circular arc of the interior profile of each pad pin is in same circle.
Said flange face is square, a screw hole is respectively arranged on square four jiaos, and said DIN type flange coupling connector is provided with four pad pin altogether, and the circular arcs of the interior profile of four pad pin are in same circle.
Low 0.05～0.09 millimeter of the height of the aspect ratio intermodulation contact ring of said pad pin.
Low 0.07 millimeter of the height of the aspect ratio intermodulation contact ring of said pad pin.
The operation principle of the preferred embodiment of the present invention is: owing to process a circle intermodulation contact ring on the DIN type flange coupling connector flange centre position; His position just exceeds four screw hole locations like this, and the screw hole location at diagonal angle just forms the seesaw effect in assembling process.When tightening one of them screw fully, the screw position at diagonal angle is certain to stick up, and at this moment removes to tighten this screw again, and flange face will arch up certainly.
Four pad pin that exceed flange face of design on four screw hole positions of flange; Make his height not be higher than the height of intermodulation contact ring; The contact that so neither influences contact ring can reduce the seesaw effect again to greatest extent, and the result is exactly when tightening one of them screw, and the screw position at its diagonal angle just can not stick up basically; When tightening this screw so again, flange just can not arch up yet.On the other hand because the position of intermodulation contact ring still is higher than the height that fill up pin, when tightening screw again, the intermodulation contact ring is preferential touch panel still, thereby makes the contact force increase, has strengthened contact reliability.
Though the cushioning pin can not be eliminated pin perk and seesaw effect fully, added the pad pin after, this effect has reduced greatly and has been enough to the intermodulation requirement that reaches very high through this mode of experiment proof.This mode has just obtained good compromise and has taken into account between increase contact force, contact reliability and seesaw effect.
Advantage of the present invention is: DIN type flange coupling connector of the present invention had both satisfied the desired intermodulation index of system, went for actual production environment again, had simplified workman's operation on the production line, also reduced workman's work difficulty.It not only makes the percent of pass of client's product intermodulation index improve greatly, thereby has reduced the time of doing over again, but also has saved the time, has improved production efficiency greatly.
