Abstract
The present invention relates to a locking mechanism of a miniature electric connector. The locking mechanism comprises a necking sleeve and a locking screw, wherein the necking sleeve is in a step structure and comprises a conical thin wall part and a round thick wall part; the middle part of the locking screw is provided with a circular groove; the necking sleeve is arranged outside the locking screw, and the conical thin wall part is mounted in the circular groove of the locking screw and meanwhile in a step fixed hole corresponding to an outer shell of the electric connector; and the abutting part of the locking screw, which is exposed out of the outer shell of the electric connector, is a full thread. The locking mechanism of the miniature electric connector occupies small space, can obtain a smaller center distance of the electric connector, be beneficial to the miniaturized development and realize the seamless attachment of a plug and a socket outer shell after being spliced.
Description
Technical field
The present invention relates to a kind of electrical connector locking mechanism, belong to technical field of electric connectors.
Background technology
The lock-screw of common miniature electric connector generally adopts split washer to be fixed on the connector shell, and typical structure as shown in Figure 1.Split washer is stuck in the cannelure of lock-screw, thereby the restriction lock-screw is deviate from from shell.The split washer of this structure must be fitted on the shell plane, must get out of the way the position of back-up ring when connector plug, socket butt joint, therefore adopts the connector of split washer structure, and lock-screw centre-to-centre spacing is general bigger.In addition, because the restriction of back-up ring and lock-screw structure, lock-screw can only be screwed into threaded portion when meshing with internal thread, and plug as shown in Figure 2, jack housing butt joint back just can not be docked to fit and be put in place, have limited the application of this retaining mechanism.
Summary of the invention
The purpose of this invention is to provide a kind of locking mechanism of miniature electric connector, the seamless applying after realizing the microminiaturized of electric connector and realizing plug, jack housing butt joint.
Locking mechanism of miniature electric connector of the present invention, form by reducing sleeve pipe and lock-screw, described reducing sleeve pipe is a ledge structure, thin-walled portion and circular thick wall part by taper are formed, described lock-screw middle part is provided with cannelure, and the reducing casing pipe sleeve is contained in outside the lock-screw, and the thin-walled portion of its taper is contained in lock-screw cannelure place, be installed in the lump in the step fixing hole of electrical connector housing correspondence, the butted part that lock-screw exposes connector shell is a full thread again.
The transition portion of described cannelure and last hypomere is a chamfering near an end of lock-screw head, and the other end is the right angle.
Description of drawings
Fig. 1, Fig. 2 are prior art electrical connector locking mechanism structure charts;
Fig. 3 is the front view of electrical connector locking mechanism of the present invention.
Among the figure: 1-shell, 2-reducing sleeve pipe, 3-lock-screw.
Embodiment
As shown in the figure, electrical connector locking mechanism of the present invention is made up of reducing sleeve pipe 2 and lock-screw 3, lock-screw 3 is provided with cannelure 4, cannelure 4 is a chamfering with transition position one end of last hypomere, the other end is the right angle, chamfering structure assurance sleeve pipe easily suit puts in place, and right-angle structure guarantees reliably to block the reducing sleeve pipe after the sleeve pipe reducing.Reducing sleeve pipe 2 is a ledge structure, and thin-walled portion intensity is relatively low, press-fit and can realize necking forming with the sleeve of a band tapering, thereby the casing clamp after the reducing is fixed on the shell lock-screw in the cannelure of lock-screw.The mating surface of sleeve pipe, lock-screw and shell has certain interval, the cannelure closed angle end of sleeve end after the reducing and lock-screw also has certain interval, these fit clearances assurance lock-screws can freely rotate on shell and not be stuck, and realize locking function when the internal thread of the lock-screw and the connector other end meshes.
Because the sleeve pipe of retaining mechanism is the thin wall circular structure, overall dimension is small, and it is little to take up room, and can obtain less connector centre-to-centre spacing, is beneficial to the microminiaturization development of connector.The sleeve pipe of this structure is embedded in enclosure, and it all be screw thread that lock-screw protrudes housing parts, so the threaded portion that protrudes of lock-screw can be screwed into the shell of the connector other end fully, can realize plug, jack housing butt joint seamless applying afterwards.
Claims (2)
1. locking mechanism of miniature electric connector, it is characterized in that: this retaining mechanism is made up of reducing sleeve pipe (2) and lock-screw (3), described reducing sleeve pipe (2) is a ledge structure, thin-walled portion and circular thick wall part by taper are formed, described lock-screw (3) middle part is provided with cannelure (4), reducing sleeve pipe (2) is sleeved on outside the lock-screw (3), the thin-walled portion of its taper is contained in lock-screw cannelure place, be installed in the lump in the step fixing hole of electrical connector housing correspondence, the butted part that lock-screw exposes connector shell is a full thread again.
2. locking mechanism of miniature electric connector as claimed in claim 1 is characterized in that: described cannelure (4) is a chamfering with an end of the close lock-screw head of transition portion of last hypomere, and the other end is the right angle.
