Description
[technical field]
The present invention is relevant a kind of cable connector combination, refers to especially a kind ofly can dock firm cable connector combination with its butt connector.
[background technology]
The combination of cable interconnection connector is to be used for the two or more independently electronic installations of electrical interconnects, like this to reach electric power and the electronic signal transmission between independent electronic.Such as, in the personal computer electronic system, except that being provided with main frame, also having various external equipments, as scan justice, printer etc., these external equipments are all set up signal by the combination of cable interconnection connector with main frame and are connected.The combination of these cable interconnection connectors generally comprises the cable connector combination of the dock connector installed on main frame and an end and external equipment electric connection, can suitably adjust the length of cable in the cable connector combination according to the distance of external equipment and main frame.The cable of cable connector combination generally all be exposed to main frame outside, no human relations are that unexpected or deliberate pulling to cable all may make cable connector combination and dock connector break away from, and have increased the unsteadiness that connects between the combination of cable interconnection connector like this.
In order to address the above problem, can in the combination of cable interconnecting connector, set up locked instrument usually.The locking mode of locked instrument generally is divided into two kinds, and a kind of is to be threaded, and another kind is that button is held connection.The United States Patent (USP) of announcing on July 13rd, 1999 has disclosed a cable interconnection connector with above-mentioned first kind of locked instrument for the 5th, 921, No. 801 and has made up, and wherein cable connector combination is provided with pair of bolts, and wherein the dock connector is provided with a pair of corresponding nut.Micro coaxial cable connector assembly is with after the dock connector docks, thereby bolt is screwed into the connection between firm connector in the corresponding nut.United States Patent (USP) the 5th in bulletin on October 26th, 1999,971, disclosed a cable interconnection connector with above-mentioned second kind of locked instrument for No. 790 and made up, wherein cable connector combination is provided with a pair of button that is positioned at its both sides and holds sheet, and wherein the dock connector is provided with the cylinder of a pair of correspondence.When cable connector combination is docked with the dock connector, at first to inwardly push the press section that described button is held the sheet rear end, the holding part that described button is held the sheet front end outwards opens by a fulcrum, then cable connector combination is docked with the dock connector, unclamp described button at last and hold the press section of sheet and make button hold the holding part homing of sheet and be held on the cylinder of correspondence of dock connector.
For the cable interconnection connector combination that can't realize the hot plug function, what no matter adopt is that above-mentioned which kind of locked instrument all can exist certain hidden danger, such as in the normal use of personal computer, owing to operating personnel's misoperation or other reason, in twisting except that the bolt on the micro coaxial cable connector assembly or pushing and all can pull out cable connector combination after buckleing on the micro coaxial cable connector assembly held the press section of sheet, may cause personal computer to work as machine thus, even may cause the current process information of personal computer to be lost.
Be with a kind of cable connector combination that when operating state, can not break away from the dock connector of, necessary design.
[summary of the invention]
The object of the present invention is to provide a kind of cable connector combination, it has the automatically controlled anti-drop device of the improper disengaging that can prevent itself and butt connector.
For achieving the above object, the present invention adopts following technical scheme: it comprises a kind of cable connector combination insulating body, is immobilizated in plurality of terminals in the insulating body, is used for interlocking with butt connector and holds device for fastening and the automatically controlled anti-drop device that is connected with butt connector with firmly, described automatically controlled anti-drop device has and stops and release condition and can changing between this two states, wherein only when described automatically controlled anti-drop device is in release condition, described device for fastening just can break away from butt connector or fasten.
Compared with prior art, cable connector combination of the present invention has following beneficial effect: by setting up automatically controlled anti-drop device, can be artificial control that device for fastening breaks away from or fasten, thereby prevented the improper disengaging of cable downlink connection device combination.
