Description

A connection mechanism that realizes quick lock separation with a threaded connection type connector

technical field

The invention relates to the technical field of radio frequency coaxial connectors, in particular to a connection mechanism for fast locking and separation with a threaded connector female end conforming to the standard IEC60169-15.

Background technique

Threaded connection series RF connectors are widely used in radio frequency transmission, usually using threaded connection, through this threaded connection, the plug and socket are pressed against each other to ensure the coincidence of their electrical reference planes. Although the reliability of this connection structure is relatively high, the disadvantage is that the connection speed is slow and the space occupied is large. There is a certain distance between the connectors to meet the use space of the installation tools, and high-density arrangement cannot be performed.

Contents of the invention

The object of the present invention is to provide a connection mechanism capable of fast locking and separation with standard threaded connector female ends and high-density arrangement in view of the deficiencies in the prior art.

The concrete technical scheme that realizes the object of the invention is:

A connection mechanism that realizes quick-lock separation with a threaded connector, characterized in that the mechanism includes an unlocking part, a locking part, a positioning part, a dielectric body, a sealing ring and an inner conductor, and the unlocking part is a screw sleeve and a positioning part The outer conductor is composed of a reed, a locking ring, a steel ball and a pressing ring, wherein the locking ring is provided with a boss, and the reed is provided with a bulge; the outer conductor is provided with a first chute and a second Two chute; the steel ball is set on the screw sleeve, and the pressing ring is set on the steel ball; the screw sleeve is set on the outer conductor, and the locking ring and the reed are pressed into the outer conductor through straight-grain press-fitting, and the dielectric body and the reed are pressed into the outer conductor. The inner conductor is put into the cavity after the outer conductor and the locking ring are matched with the reed, and the sealing ring is arranged on the outer wall of the reed.

The present invention is simple in structure, durable and reliable, and can realize reliable butt joint with general threaded connection type female end, only needs a push-pull action to fully realize the locking and separating function of the connector, the operation is very convenient, and the locking and separating are quick. It has the characteristics of quick plug-in, high reliability, excellent mechanical and electrical performance, simple assembly and low cost.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is a schematic diagram of an unlocked state according to an embodiment of the present invention;

Fig. 3 is a schematic diagram of a locked state of an embodiment of the present invention.

Detailed ways

Referring to Fig. 1, the present invention comprises unlocking part, locking part, positioning part, medium body, sealing ring and inner conductor, and described unlocking part is screw sleeve 1, and positioning part is outer conductor 9, and locking part is made of reed 4, The locking ring 2, the steel ball 8 and the pressing ring 7 are composed, wherein the locking ring 2 is provided with a boss 21, and the reed 4 is provided with a bulge 4; the outer conductor 9 is provided with a first chute 91 and a second The chute 92; the steel ball 8 is set on the screw sleeve 1, and the compression ring 7 is set on the steel ball 8; the screw sleeve 1 is set on the outer conductor 9, and the locking ring 2 and the reed 4 are press-fitted by straight lines. Insert the outer conductor 9, the dielectric body 5 and the inner conductor 6 into the cavity after the outer conductor 9 and the locking ring 2 cooperate with the reed 4, and the sealing ring 3 is arranged on the outer wall of the reed 4.

Example

Referring to Figure 1, Figure 2 and Figure 3, apply a thrust at any position on the screw sleeve 1, and the locking member slides from the first chute 91 of the outer conductor 9 to the second chute through the steel ball 8 on the screw sleeve 1 92 position, the locking ring 2 is automatically opened, so that it can be docked with the product 10. When the butt end is inserted and the end surface of the butt end is in full contact with the product 10, apply an axial thrust at any position on the screw sleeve 1 in the direction shown in the figure, and the locking member passes through the steel ball 8 on the screw sleeve 1 again, and from the outer conductor 9 The position of the second chute 92 slides to the position of the first chute 91, so that the boss 21 on the locking ring 2 returns, and the butt end is clamped to realize self-locking (the state in Figure 3); when unlocking, the locking member passes through the screw sleeve The steel ball 8 on 1 slides from the position of the first chute 91 of the outer conductor 9 to the position of the second chute 92, so that the locking effect of the boss 21 on the locking ring 2 on the butt end disappears and bounces off (Fig. 2 status) to achieve quick separation from the docking end.

Claims (1)

1. realize the bindiny mechanism that fast lock separates with screw connected connector for one kind, it is characterized in that this mechanism comprises unlock piece, locking member, keeper, dielectric, sealing ring and inner wire, described unlock piece is that swivel nut, keeper are that outer conductor, locking member are comprised of reed, binding ring, steel ball and hold-down ring, wherein binding ring is provided with boss, and reed is provided with bulge; Outer conductor is provided with the first chute and the second chute; Steel ball is located on the swivel nut, and hold-down ring is located on the steel ball; Swivel nut is set on the outer conductor, and binding ring and reed are pressed in the outer conductor after being press-fitted by straight burr, and dielectric and inner wire are packed in outer conductor and binding ring and the cavity after reed cooperates, and sealing ring is located at the reed outer wall; Wherein:
