Abstract
The invention relates to the field of signal connectors, in particular to a pulling unlock optical connector and a pulling unlock electric connector. With an inserting end as the front end, the pulling unlock optical connector comprises a housing and an optical contact element, wherein an elastic clamp which is used for being in locking fit with an adaptive connector is arranged on the housing; the elastic clamp is connected with a stay cord; the stay cord is matched with a reversing mechanism on the housing; the reversing mechanism can convert backward movement of the rear end of the stay cord into downward movement of the front end of the stay cord; the rear end of the stay cord is connected with a pull sleeve; and a pull sleeve is assembled on the housing in a sliding manner along the front-and-back direction. The rear end of the stay cord of the pulling unlock optical connector provided by the invention is connected with the pull sleeve; and the pull sleeve is assembled on the housing in the sliding manner along the front-and-back direction, so that the problems that the stay cord is in disorder and the connector is drawn by mistake are directly eliminated thoroughly; in addition, the pull sleeve only needs to be directly held when the pulling unlock optical connector is unlocked; and after the stay cord is tightened, the optical connector can be driven to be separated from the adaptive connector by further pulling the pull sleeve. Therefore, convenience is also provided for extraction of the optical connector from another aspect.
Description
Technical field
The present invention relates to signal connector field, particularly relate to a kind of optical connector and electric connector pulling unblock.
Background technology
Along with the development of Fibre Optical Communication Technology, the application of the optical fiber connector is more and more extensive.As the core component of the optical fiber connector, light contact, owing to being subject to the impact of the characteristics such as its material, needs protected by corresponding housing in outside.
At present, conveniently lock and unlock, the housing of some optical connectors is provided with elastic card, and elastic card is provided with lock dog, in the process used, when plugging together locking with intermateable connector, first elastic card is pressed down distortion, and lock dog is dynamic with the distortion of elastic card, after grafting puts in place, elastic card resilience, thus by lock dog, corresponding optical connector assembly is locked; Correspondingly, when needs are by optical connector components apart, then need first to press down elastic card, then the optical connector of band elastic card can be extracted from intermateable connector.
The optical connector of said structure is little in density, environment space is abundant, really soon insert and pull out soon, characteristic easy to use, but when densely arranged, the Multi-layers distributing of connector or elastic card insert darker in intermateable connector, pressing operation elastic card just seems very inconvenient.
For the problems referred to above, the Chinese patent that the day for announcing is CN202649527U, the day for announcing is on January 2nd, 2013 is carried and is disclosed a kind of duplexing DLC plug, this duplexing DLC plug is connected to stay cord on the elastic card of optical connector, connector shell is passed by the commutating structure on connector shell in the rear end of stay cord, stay cord afterbody conversion of motion backward can be the downward motion in its front end by commutating structure, thus orders about the descending unblock of elastic card.
Although above-mentioned duplexing DLC plug pulls unblock by the stay cord extending to pin tail, but owing to when carrying out unlocking operation being the afterbody of direct pull stay cord, and stay cord this as flexible material and length is longer, and the cable of tail portion of connector can block stay cord, when connector is installed intensive, not only be not easy to get at stay cord, and the stay cord on each connector is easy to obscure, causes the problem of by mistake pulling out to occur.In addition, above-mentioned connector unlocks by tractive stay cord, and therefore stay cord only can play the effect of unblock, and it can not realize pulling separation to connector, still cannot solve the problem that inconvenience extracted by optical connector.
In prior art, some electric connectors also use the retaining mechanism being with above-mentioned elastic card, such as RJ-45 plug etc., adopt the unblock of the electric connector of the retaining mechanism of band elastic card also to there is the problem identical with optical connector with being separated.
Summary of the invention
The object of the present invention is to provide a kind of optical connector pulling unblock, the problem of extracting inconvenience existed with the optical connector solving existing employing elastic card Zuo Jin mechanism.
Meanwhile, the present invention also aims to provide a kind of electric connector pulling unblock, the problem of extracting inconvenience existed with the electric connector solving existing employing elastic card Zuo Jin mechanism.
In order to solve the problem, of the present inventionly pull the optical connector of unblock by the following technical solutions: the optical connector pulling unblock, this optical connector take inserted terminal as front end, it comprises shell and light contact, shell is provided with for locking friction tight elastic card with intermateable connector, elastic card is connected with stay cord, stay cord coordinates with the changement on shell, stay cord rear end conversion of motion backward can be the downward motion in its front end by changement, the rear end of stay cord is connected with helps pull a cart, and helps pull a cart and is slidedly assemblied on shell along the longitudinal direction.
Described helping pull a cart coordinates with spin-ended between shell.
Described outside wall surface of helping pull a cart is provided with anti-skid structure.
Releasable connection between described stay cord and elastic card.
Describedly help pull a cart as split-type structural, be clasped between its each several part.
Pull the electric connector of unblock by the following technical solutions: the electric connector pulling unblock, this electric connector take inserted terminal as front end, it comprises shell and electric contact piece, shell is provided with for locking friction tight elastic card with intermateable connector, elastic card is connected with stay cord, and stay cord coordinates with the changement on shell, and stay cord rear end conversion of motion backward can be the downward motion in its front end by changement, the rear end of stay cord is connected with helps pull a cart, and helps pull a cart and is slidedly assemblied on shell along the longitudinal direction.
Described helping pull a cart coordinates with spin-ended between shell.
Described outside wall surface of helping pull a cart is provided with anti-skid structure.
Releasable connection between described stay cord and elastic card.
Describedly help pull a cart as split-type structural, be clasped between its each several part.
Pull the rear end of the stay cord of the optical connector of unblock to be connected with to help pull a cart, help pull a cart and be slidedly assemblied on shell along the longitudinal direction due to of the present invention.Therefore directly stay cord entanglement is thoroughly eliminated, the problem that connector pulls out by mistake; In addition, owing to not needing the hand-holdable position finding stay cord again, only need during unblock directly to pinch and help pull a cart, after stay cord is tauted, continue to pull to help pull a cart and can order about optical connector and be separated with intermateable connector, this is also from another point of view for extracting of optical connector provides conveniently.
