Description
Technical field
The utility model belongs to technical field of electric connectors, especially belongs to quick locking structure in a kind of coaxial connector.A kind of bindiny mechanism with quick locking and quick separation function, this bindiny mechanism is mainly used in the radio frequency (RF) coaxial connector field.
Background technology
The connection of coaxial connector and retaining mechanism are very important parts in the coaxial connector, and it has crucial influence to the reliability of connector and the applicability of application scenario.
Disclosed product in patents such as US5088937, DE3117320 and EP0867978A2 adopts the locking mode that is threaded respectively, is threaded by this, and plug and socket compress mutually, to guarantee the coincidence of its electric datum level.But this locking mode that is threaded can not be realized fast insert-pull, the butt joint of connector, separates and has expended the long time, and must leave the minimum range of placing assembling tool between connector and connector, and packing density is lower.
Therefore, we need a kind of installation simple, the coaxial connector of dependable performance, and the realization rapid abutting joint plugs and locks, separates, convenient installation.
Summary of the invention
Technical problem to be solved in the utility model provides quick locking structure in a kind of coaxial connector, realize the rapid abutting joint plug locking of coaxial connector, locking and the radio frequency connector that separates fast, comprise plug and socket, wherein plug comprise collar, sheath, back-up ring, big spring, little spring, separate lock tube, outer conductor a and locking steel ball, outer conductor b etc.Socket comprises outer conductor, inner wire and dielectric etc.The locking steel ball is contained in the hole on the outer conductor b, and its inside and outside both sides contact with sheath and collar respectively.The outer conductor b outside is equipped with big spring, and installed inside has little spring, and big spring and little spring all have precompression, and the precompression of big spring forces collar to support and compressing locking steel ball greater than the precompression of little spring.Outer conductor a and outer conductor b pack little spring and sheath wherein into by being press-fitted, and being press-fitted of back-up ring and outer conductor b forms a whole all parts.
Collar is an inclined-plane and a step with locking steel ball contact position, when the plug and socket of connector is in non-locking state, under the assistance of big spring, by the extruding of the step on collar steel ball; When the plug of connector, when socket is in locking state, by the extruding of the inclined-plane on collar steel ball.
Adopt the utility model structure to have following advantage:
A, this locking mechanism, with to separate releasing force very little, butt joint and locking are rapidly to relay;
When b, the butt joint of this structure, release put or the connector tail cable on apply power, all can realize the rapid abutting joint of plug and socket; During release, can easily realize release (if releasing force is applied on the cable, 200N pulling force ability release at least) as long as put the power of applying in release;
C, this locking mechanism can provide bigger interface confining force (being coupling mechanism force), guarantee the plug and socket reliable lock of connector, have very high electric and mechanical performance.

Embodiment
To a kind of quick locking structure in the coaxial connector of preferred embodiment manufacturing of the present utility model, radio frequency connector is described in further detail below in conjunction with above-mentioned accompanying drawing.
Present embodiment plug (1) is by an outer conductor b18 that a plurality of locking steel balls 13 are housed, a locking mechanism of forming by locking steel ball 13, collar 16, big spring 14, little spring 11, sheath 12, the lock tube 15 of separating that plays the release effect is formed, and, all parts are fixed into an integral body by being press-fitted of back-up ring 17, outer conductor a10 and outer conductor b18.
Present embodiment has adopted 8 locking steel balls 13, and they circumferentially are distributed in the hole of outer conductor b18, inboard contacts with sheath 12, and the outside closely contacts with step 161 on the collar 16, shown in Fig. 1 a, Fig. 1 b.Sheath 12 is pressed in locking steel ball 13 in the hole on the outer conductor b18 under the extruding of little spring 11, locks steel ball 13 simultaneously and is subjected to extruding force from collar 16.In addition, big spring 16, with little spring 15 certain precompression is arranged all, and big spring 16 precompressions are bigger.
Accompanying drawing 2 is socket (2) structural representations (part relevant with quick locking structure only is shown here) of the utility model embodiment.It comprises an outer conductor 21, which is provided with the boss 210 and the groove 211 that work when connector butt joint, locking.
Accompanying drawing 3 is plug (1), socket (2) butt joint schematic diagrames of the utility model embodiment.As shown in Figure 3, boss 210 extruding sheaths 12 on the socket outer conductor 21, compression little spring 11, sheath 12 is moved backward, simultaneously, locking steel ball 13 still is positioned at the hole on the outer conductor b18 under the radial compression of boss 210, locking steel ball 13 outsides still are subjected to top bar 161 squeezing action of collar 16.Because during step 161 extruding steel balls 13, the radial pressure that produces on steel ball 13 is less, therefore, only need lessly axially to relay, can easily realize docking of connector plug (1) and socket (2).
Accompanying drawing 4 is plug (1), local structure for amplifying schematic diagrames of socket (2) locking of the utility model embodiment.
When outer conductor 21 moves into place, inclined-plane 162 extruding locking steel balls 13, the very little inclined-plane 162 of angle (15 about degree) changes into very big inboard footpath pressure with the precompression of big spring 14, and by locking the transmission of steel ball 13, act on the outer conductor 21, at this moment, locking steel ball 13 being stuck in outer conductor 21 upper grooves 210 tightly, as shown in Figure 4, so just, define the axial relative motion of plug (1), socket (2), for interface provides very big extruding force, guaranteed the high reliability that plug (1) is mechanical with socket (2), be electrically connected simultaneously.
When plug (1), socket (2) separated release, its state state when docking was similar, as shown in Figure 3.During separation, opposition acts on outer conductor 21 respectively and separates on the lock tube 15, separate lock tube 15 and drag collar 16, compression big spring 14, extruding force on the locking steel ball 13 is shed, therefore, locking steel ball 13 is got back under the squeezing action of outer conductor 21 convex platforms 210 in the hole on the outer conductor b18, realizes release.Simultaneously, in separation process, sheath 12 is got back to initial position (resetting) under the extruding of little spring 11, and will lock steel ball 13 once more and be squeezed in the hole.
Connector construction of the present utility model is durable reliable, and antivibration, anti-impact only need the action of a push-and-pull just to realize the locking and the separation function of connector fully, and be easy to operate, locks and separates rapidly.
