Description
Technical field the present invention relates to the connector of electronic equipment circuit, particularly coaxial connector.
The coaxial connector kind that background technology is released at present in the world is a lot, for example 1.85mm, 2.4mm, K type (2.92mm), 3.5mm, SMA, N Connector etc., and employing is threaded; Blind plug-in connectors such as SMB, SMC, BMA, SMP are also arranged.In these connectors, adopt the connector connection reliability height be threaded, but its connections generally need be rotated multi-turn with swivel nut when connecting, efficient is lower, and rotates and limited by usage space, and is not very convenient, is not suitable for quick test occasion.Convenient when blind plug-in connector such as SMP uses, but the anti-adverse environment ability, and can not compatiblely use with the connector that is threaded.In order to solve the needed tests quickly and easily of process such as production, both at home and abroad all at the corresponding connector of active development at threaded connector port.
The exploitation at the coaxial connector for quick connection of the connector that is threaded both at home and abroad is primarily aimed at N type, SMA type connector at present.Figure 1 shows that existing a kind of coaxial connector for quick connection at the SMA type, its structure comprises inner wire 1, dielectric support 2, outer conductor 4 and adhesive 3, at the outer conductor inner space elasticity outer conductor is housed, this elasticity outer conductor is the annulus that an outer surface is step, this annulus has two kinds of external diameters of size, have some equally distributed inside and outside grooves that connect on the part annulus 6 that wherein external diameter is little vertically, the big part annulus 5 of external diameter between outer conductor and dielectric support and with its interference fit.The shortcoming of the coaxial connector for quick connection of this structure is, when the outer conductor of connected connector inserts between outer surface and the outer conductor 4 of annulus 6 of elasticity outer conductor the realization self-locking, because the existence of groove, discontinuous situation appears in the connection of both sides' outer conductor, thereby electric property is produced harmful effect.The applying frequency upper limit of present this coaxial connector for quick connection generally below 24GHz, can not be used on connectors such as the higher 3.5mm of frequency, 2.92mm, 2.4mm type.
At the be threaded coaxial connector for quick connection of connector of high frequency, the difficult point of its development is, should realize connecting fast guaranteeing to meet on the basis that the corresponding connectors interface requires, comprise guarantee outer conductor continuously and realize self-locking.
Summary of the invention the purpose of this invention is to provide a kind of coaxial connector for quick connection, and this connector can guarantee that outer conductor is continuous and realize self-locking, thereby is applicable to the quick connection of the connector that is threaded of high frequency.
The objective of the invention is to be achieved through the following technical solutions: a kind of at the be threaded coaxial connector for quick connection of connector of high frequency, comprise inner wire, dielectric support, outer conductor, it is characterized in that outer conductor is made of 3 parts first, second, third, 3 parts are the cylinder that outer surface is step, outer conductor second is positioned at the inboard of outer conductor first, leave certain space between outer conductor first and the outer conductor second, can make outer conductor third be positioned at this space, outer conductor third is the elasticity outer conductor, and its axial length is not more than the length in this space.
Said outer conductor third is the annulus that an outer surface is step in the technique scheme, this annulus has two kinds of external diameters of size, have some equally distributed inside and outside grooves that connect on the part annulus that wherein external diameter is little vertically, the big part annulus of external diameter between outer conductor and dielectric support and with its interference fit or threaded engagement.The structure of outer conductor third and elasticity outer conductor shown in Figure 1 are similar.
The quantity of said elasticity outer conductor fluting is not less than 4 in the technique scheme, and its position is uniformly distributed along the circumference.The material of elasticity outer conductor should be elasticity material preferably, as beryllium-bronze.
Said dielectric support is the disk shape in the technique scheme, and central authorities are porose, and its material is high-intensity macromolecular material.This material can be polyimides (PI), Polyetherimide (PEI) or polyether-ether-ketone (PEEK).Adopt the advantage of this supporting way to be, can eliminate adhesive, improve the electric property of connector dielectric property and the harmful effect that causes.
On the periphery in the technique scheme between the adjacent twice fluting of said elasticity outer conductor bossing is arranged.The effect of this bossing is to realize self-locking after connected connector snaps in the elasticity outer conductor.
The basic ideas of technique scheme are: elasticity outer conductor of the prior art had both been born the function of microwave transmission, born the auto-lock function of quick connection again, two kinds of functions condition each other, can't take into account between the continuity of outer conductor and the realization self-locking, thereby electric property has been produced harmful effect.If increase quantity to 3 parts of outer conductor, above-mentioned two kinds of functions are born by outer conductor second and outer conductor third respectively, because outer conductor third is the elasticity outer conductor, its axial length is not more than the length in this space, after connected connector snaps in the elasticity outer conductor, can form the complete interface of tight contact between the outer conductor second of former connector and the outer conductor of connected connector, thereby guarantee the continuity of outer conductor.
Advantage of the present invention is: one, outer conductor can keep continuous between connector and the connected connector; Two, also can realize self-locking easily between the two, thus the quick connection of the connector of can realizing being threaded, three, good electric property is arranged, can on the high frequency coaxial hookup, use.
