Embodiment

Below in conjunction with the embodiment accompanying drawing the present invention is done further detailed description:

Quick end joint connector according to the invention is made up of plug and socket, and wherein plug comprises: plug insulator 1 and negative contact 16, and negative contact 16 comprises reed 2, negative contact holder 3, handle 4, locating piece 5, rubber blanket 6; Plug insulator 1 inner hole wall is provided with Elastic Teeth 9, exterior circumferential cloth stay 12, and the reed 2 of negative contact is fastened on its contact holder 3 by riveted way; This holder endoporus rear end is provided with ratchet 10, and is unidirectional array, and 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 the end face with handle 4; The component of handle 4, locating piece 5 and rubber blanket 6 compositions is assembled to the ratchet place of contact 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, and has wider conductor termination scope, and practicality is stronger.

Negative contact and conductor termination were carried out negative contact shown in Figure 7 and lead 15 termination process sketch mapes before the pin insulator of packing into.According to the thickness of lead core, turning handle 4 is adjusted itself and the component position of locating piece 5 with 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; Can lead further be pressed abd fixed on its contact 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, and in order to make pack into the length of negative contact of every lead consistent; In its contact 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, on the mating surface of contact holder 3 and lead, be provided with anti-slop serrations, 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 contact holder 3; Lead is just terminated on the contact holder 3 securely, thereby realizes the termination of negative contact and lead.

When pin insulator 1 was connected with negative contact 16, the Elastic Teeth of pin insulator 1 was strutted by negative contact 16, pack into put in place after, the Elastic Teeth of pin insulator 1 is homing again, and is stuck on the outside step of negative contact.The negative contact reach of the step limits of pin insulator 1; And the Elastic Teeth of pin 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 pin insulator 1; Form the contact fixed structure of confirming, satisfy normally plugging together and the functional requirement that separates.

Socket comprises: socket insulator 7 and positive contact 17; Positive contact 17 comprises inserted sheet 8, positive contact holder 3, handle 4, locating piece 5, rubber blanket 6; Socket insulator 7 endoporus are provided with Elastic Teeth; The outside is provided with the window step 13 that cooperates with pin insulator 1 stay 12, and the structure of positive contact 17 each part of rear end and type of attachment are identical with negative contact 16 rear ends, and what be that positive contact holder 3 front ends are fixedly connected is inserted sheet 8.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 socket 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 pin insulator 1 withdraw from the window step of socket 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.
