Description
One, technical field:
The utility model relates to a kind of connector that is used for the microwave transmission every field, especially relates to a kind of self-locking stationary phase connector that pushes.
Two, background technology:
In the background technology, radio frequency (RF) coaxial connector works effects such as connecting coaxial transmission line, microstrip circuit and printed panel in microwave transmission circuit, has bandwidth, characteristics such as easy to connect, reliable, is widely used in the every field of microwave transmission.Radio frequency (RF) coaxial connector is because the difference of application scenario has multiple connected mode, common is threaded, bayonet coupling, plug-in type connects and push self-locking connects.The characteristics such as having reliability height, superior electrical property that are threaded, but its connection speed slow, require that enough surrounding spaces are arranged, be difficult to realize connect fast and arrange with high density.Plug-in type and bayonet coupling are quick, but electrical property and resistance to shock are poor, the occasion that is difficult to have relatively high expectations.Push self-feeding type connector and have the characteristics such as rapid, reliable that connect, but common pushes self-feeding type connector because its linkage interface complex structure, the tolerance stack of a plurality of sizes changes greatly the linkage interface electrical length, the cost height can not be used in electrical performance indexes and have relatively high expectations and have in the machine system that phase place requires.
Three, summary of the invention:
The utility model provides a kind of self-locking stationary phase connector that pushes in order to solve the weak point in the above-mentioned background technology, its phase stabilization, and vibration resistance is strong, connects quick.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of self-locking stationary phase connector that pushes, its special character is: comprise mechanical connection unit and electrical connecting unit, the mechanical connection unit comprises shell, slide block surrounds on the shell, be connected with lock sleeve on the shell, be removable the connection between shell and the lock sleeve, electrical connecting unit comprises shell, is removable the connection between the shell in the shell in the mechanical connection unit and the electrical connecting unit.
Can be with spring on the shell in the above-mentioned electrical connecting unit, be connected with nut by packing ring between the shell in the shell in the electrical connecting unit and the mechanical connection unit.
Above-mentioned slide block can surround by the snap ring of outer-enwraped type spring coil on the shell in the mechanical connection unit.
Above-mentioned lock sleeve can be connected with shell in the mechanical connection unit by the breach snap ring.
Can be provided with insulation between shell in the above-mentioned electrical connecting unit and the contact pin and support, be provided with insulator between the lining in contact pin and the shell.
Can be connected by lining, wire clamp and nut between shell in the above-mentioned electrical connecting unit and the cable.
The utility model against existing technologies, its advantage is:
The utility model will insert the self-locking structure part and be divided into two parts with electrical connections, make electrical connections force contact by holddown spring, and complicated retaining mechanism dimensional tolerance is not exerted an influence to being electrically connected the interface, guarantee the stable of electrical performance indexes.It has phase stabilization, and vibration resistance is strong, connects characteristics efficiently, can have 50 Ω or 75 Ω characteristic impedances, can be widely used in the every field of microwave transmission.
Four, description of drawings:
Accompanying drawing is the utility model structural representation;
Five, embodiment:
Referring to accompanying drawing, the design that the utility model adopts mechanical connecting part to separate with electrical connections, mechanical connecting part comprises snap ring 5, breach snap ring 7, shell 8 and the nut 12 of lock sleeve 3, slide block 4, spring coil, and electrical connections comprises shell 6, insulation support 9, contact pin 10, packing ring 14, insulator 13, nut 15, wire clamp 16 and lining 17.Mechanical connecting part and electrical connections can slide relative, adopt spring to force the electrical connection interface way of contact that compresses, by spring 11 determine the relative position of two parts free states and connect after contact pressure.Socket comprises shell 1 and jack 2 in the accompanying drawing, and the mechanical connection unit comprises shell 8 in the plug, and the snap ring 5 of outer-enwraped type spring coil surrounds slide block 4 on the shell 8, plays the effect that radially slides.The breach snap ring of making of beryllium-bronze material 7 is connected lock sleeve 3 on the shell 8, and lock sleeve 3 can be moved axially, and realizes locking and release.Electrical connecting unit comprises shell 6, and the spring 11 of steel wire coiled is enclosed within on the shell 6, and the barrier by packing ring 14 is connected shell 6 with nut 12 with shell 8, play central role of the present utility model, forces to compress to be electrically connected the interface.Insulation is supported 9 and is located at and makes contact pin 10 and shell 6 keep concentric in the shell 6, and insulator 13 is clipped in contact pin 10 and the lining 17, can avoid contact pin 10 after contract.Lining 17, wire clamp 16 and nut 15 can reliably contact connector institute distribution cable with connector shell 6.
Referring to accompanying drawing, during real work, when socket pushed plug, size L1 ' must be less than L ' in the connector in the past, and L1 must be greater than L, otherwise slide block 4 can't fall into groove A, and connector can not be realized self-locking.Consider that from electrical property size L and L1 are approaching more, then linkage interface rocks more for a short time, and electricity function index and stability thereof are good more.But because the accumulation of tolerance in the course of processing, the difference of L and L1 is a very big value, and bigger rolling momentum is arranged between plug and the socket, and the electrical pickoff position is in variable condition all the time, so just do not reach higher electrical performance indexes, more do not have the effect of steady phase.The utility model is decomposed into shell 8 in the mechanical connection unit and the shell 6 in the electrical connecting unit with an original shell, shell 6 and shell 8 can be produced endwisely slip.When not plugging together, because the effect of spring 11 makes shell 6 compress in the D face with shell 8 and contacts, this moment, L reached maximum L0.Make L '＞L1 ' during design, L0 〉=L1+ (L '-L1 ')+Δ (Δ is a set point), can guarantee when then plug docks with socket that the B face contacts earlier with C kept man of a noblewoman, select the suitable Δ value (about 1mm) and the precompression of spring 11, can guarantee that connector butt joint back electric interface is forced to compress contact, rocking after can effectively avoiding pegging graft, thereby reach the effect of steady phase.
