Embodiment

The present invention is described in further detail below in conjunction with the embodiment accompanying drawing:

Quick end joint connector of the present invention is made up of plug and socket, wherein plug comprises:insulator 1 and negative contact 16, negative contact 16 comprises reed 2, holder 3, handle 4, locating piece 5, rubber blanket 6, insulator 1 inner hole wall is provided with Elastic Teeth 9, exterior circumferential cloth stay 12, the mode that the reed 2 Tong Guo of negative contact connect is fastened on the holder 3, holder endoporus rear end is provided with ratchet 10, and be unidirectional array, locating piece 5 and rubber blanket 6 are packed in the eccentric orfice of handle 4, the quantity of packing into of locating piece 5 is two, push the locating piece 5 at two ends then and do relative motion, this moment, rubber blanket 6 was compressed, when the end face of locating piece 5 moves to end face with handle 4, with handle 4, the component that locating piece 5 and rubber blanket 6 are formed is assembled to the ratchet place of holder 3, because ratchet 10 is a unidirectional array, component can only be realized downward slip under the resilient support of rubber blanket 6.This moment, component rested on more top position to satisfy the conductor termination in max line footpath, adjust the stop place of component during use again according to the thickness of lead 15 cores, can realize the conductor termination of different thicknesses, the lead that guarantees different thicknesses all can obtain the firm connection that compresses, have wider conductor termination scope, practicality is stronger.

Negative contact and conductor termination were carried out before the insulator of packing into, Figure 5 shows that negative contact and lead 15 termination process schematic diagrames.Thickness according to the lead core, turning handle 4 is adjusted itself and the component position of locating piece 5 and rubber blanket 6 compositions, because ratchet is a unidirectional array, component can only be realized slip forward, apply certain pressure, after component is slided into the contact wire core and has certain initial pressure, be rotated further handle 4, lead further can be pressed abd fixed on the holder 3, and reach the termination confining force of regulation.Handle 4 is an eccentric wheel structure, offset can design according to actual needs, in addition, in order to make pack into the length unanimity of negative contact of every lead, in holder 3, be provided with positioning boss, boss compresses the back at lead and stops the lead reach except that the initial position unanimity that guarantees lead, can avoid handle 4 to rotate the failure phenomenon that compresses that causes.In addition, be provided with anti-slop serrations on the mating surface of holder 3 and lead, anti-slop serrations 11 is a unidirectional array, and handle 4 is pressed on lead can prevent effectively on the anti-slop serrations that lead from retreating.

After negative contact and the conductor termination, it is loosening that displacement forward can prevent also that by the positioning boss restriction rotation of handle 4 from causing, displacement backward is by the anti-slop serrations restriction of handle 4 and holder 3, and lead is just terminated on the holder 3 securely, thereby realizes the termination of negative contact and lead.

When insulator 1 was connected with negative contact 16, the Elastic Teeth of insulator 1 was strutted by negative contact 16, pack into put in place after, the Elastic Teeth of insulator 1 is homing again, and is stuck on the step of negative contact outside.The negative contact reach of the step limits of insulator 1, and the Elastic Teeth of insulator 1 is stuck on the step of negative contact, move after placing restrictions on negative contact, forward and displacement backward be limited fixing after, negative contact just is fixed in the insulator 1, form the contact fixed structure of determining, satisfy normally plugging together and the functional requirement that separates.

Socket comprises: insulator 7 and positive contact 17, positive contact 17 comprises inserted sheet 8, holder 3, handle 4, locating piece 5, rubber blanket 6, insulator 7 endoporus are provided with Elastic Teeth, the outside is provided with the window step 13 that cooperates with insulator 1 stay 12, the version of positive contact 17 rear ends is identical with negative contact 16 rear ends, the fixedly connected inserted sheet 8 of positive contact holder 3 front ends.Positive contact 17 is identical with negative contact 16 with the termination mode of lead.

After connector plug of the present invention, socket butt joint plugged together and put in place, stay 12 steps of pin insulator 1 were stuck in the window step 13 places realization plug of insulator 7 and the locking of socket.When plug separates with socket, only need the free-hand stay of holding with a firm grip, make the stay step of insulator 1 withdraw from the window step of insulator 7 after, plug can separate with socket in release.

Quick end joint connector of the present invention need not be equipped with other specific purpose tool because of adopting said structure, realizes that not collinear footpath lead is connected and separates with the quick of socket with fast firm termination, the plug of contact, has stronger practicality.
