Description
Technical field
It the utility model is related to connector, and in particular to a kind of connector with dual fail-safe pipe.
Background technology
Existing connector is general only nearby to set a protective tube to carry out overcurrent protection when carrying out overcurrent protection,
When connector breaks down, user, which can not determine which end that bottom is system both positive and negative polarity exactly, breaks down, Zhi Nengqu
Lower protective tube confirms to the both positive and negative polarity circuit of system respectively；Existing single protective tube carries out overcurrent protection in addition, only right
One of system positive-negative polarity has carried out overcurrent protection, and user is not powering off hard disk, power supply or board of taking-up and replacing damage etc.
During part, the risk of the parts such as damage hard disk, power supply or board be present.
Utility model content
For above-mentioned deficiency of the prior art, the connector provided by the utility model with dual fail-safe pipe can be exactly
There is failure in which polarity of judgement system, can carry out overcurrent protection to the both positive and negative polarity of circuit simultaneously.
In order to reach foregoing invention purpose, the technical solution adopted in the utility model is：
A kind of connector with dual fail-safe pipe is provided, it includes housing and the positive terminal and negative pole end that are installed in housing
Son；A storage tank is offered on housing, be provided with storage tank with two sections of termination contacts before and after positive terminal and negative terminal,
Fuse component for overcurrent protection；Fuse component includes mounting shell, and two protective tubes, two guarantors are provided with mounting shell
Dangerous pipe two end in contact with two sections of terminals before and after positive terminal and negative terminal respectively；Each protective tube and a resistor coupled in parallel
Connection, and each resistance is connected with the indicator lamp installed in mounting shell end.
The beneficial effects of the utility model are：This programme is respectively arranged with one and positive terminal negative terminal positive terminal
With the protective tube of two sections of termination contacts before and after negative terminal, one of polarity breaks down, and its corresponding protective tube can be
Burnt out under high current effect, indicator lamp will be lighted, and such user only needs to enter corresponding polarity according to the prompting of indicator lamp
Row maintenance, accurate quick.
, so can be with safer carry out hot plug because dual fail-safe pipe can realize that both positive and negative polarity is protected, i.e., user is not
Closing system, the parts such as hard disk, power supply or the board of damage are taken out or changed in the case of not cutting off the electricity supply, are so as to improve
Timely recovery capability, autgmentability and flexibility united to disaster etc..

Embodiment
Specific embodiment of the present utility model is described below, in order to which those skilled in the art understand
The utility model, it should be apparent that the utility model is not limited to the scope of embodiment, to the common skill of the art
For art personnel, if various change in the spirit and scope of the present utility model that appended claim limits and determines,
These changes are it will be apparent that all utilize the innovation and creation of the utility model design in the row of protection.
The structural representation after the upper lid 38 of the taking-up of fuse component 3 is shown with reference to figure 1 and Fig. 2, Fig. 1, Fig. 2 shows guarantor
The decomposing schematic representation of the housing 1 of front and rear two section terminal of the dangerous tube assembly 3 with being provided with positive terminal 5 and negative terminal 4.Such as Fig. 2
Shown, the connector with dual fail-safe pipe includes housing 1 and the positive terminal 5 and negative terminal 4 that are installed in housing 1.
As shown in figure 1, offering a storage tank 2 on housing 1, it is provided with storage tank 2 and positive terminal 5 and negative pole end
Front and rear two sections of termination contacts of son 4, the fuse component 3 for overcurrent protection；Front and rear the two of positive terminal 5 and negative terminal 4
The cleft hand structure for clamping protective tube is respectively provided with Duan Duanzi.
Fuse component 3 includes mounting shell, is provided with two protective tubes 35 in mounting shell, two protective tubes 35 respectively with
Two end in contact of front and rear two sections of terminals of positive terminal 5 and negative terminal 4；Each protective tube 35 is in parallel with a resistance 37 even
Connect, and each resistance 37 is connected with an indicator lamp 33 installed in mounting shell end.
When current is excessive, wherein the protective tube 35 corresponding to the polarity to break down will burn under high current effect
Bad, indicator lamp 33 will be lighted, and user prompts to carry out corresponding operating, accurate quick according to indicator lamp 33.
Two protective tubes 35 are parallel to each other, and parallel with direction interpolation with positive terminal 5 and negative terminal 4.Protective tube 35 is adopted
It is arranged on this mode inside mounting shell, space can be saved, make fuse component 3 compact-sized, the company of reduce further
The volume of device is connect, realizes the compact design of connector.
In one embodiment of the present utility model, mounting shell includes the upper lid 38 and lower cover 31 snapped together, reference
Fig. 1 and Fig. 3, protective tube 35, resistance 37 and indicator lamp 33 therein are installed in inside mounting shell.Using the installation of this structure
Shell can be easily installed the processing of shell and the installation of all parts.
As shown in Figure 3 and Figure 4, offer on upper lid 38 and installed for protective tube 35, and with positive terminal 5 and negative pole end
The cell body 381 of front and rear two sections of termination contacts of son 4.The setting of cell body 381, in order to simplified mounting shell, positive terminal 5 and it can bear
The structure of extreme son 4, it is ensured that the quick assembling of whole connector.
As shown in figure 1, when implementing, protective tube 35 passes through in parallel with connector 36, fixture 34, resistance 37 and indicator lamp 33
Connection.Fixture 34 therein has elastic piece structure, ensures the conduction with protective tube.Connector 36 therein is using similar harpoon
Structure, ensure the conduction that indicator lamp 33 and resistance 37 electrically connect.
In summary, this programme connects both positive and negative polarity respectively using dual fail-safe pipe, while electricity guarantor was carried out to circuit both positive and negative polarity
Shield, and carries indicator lamp, can which pole of accurate judgement system go wrong；After being protected using both positive and negative polarity, connector can more pacify
Hot plug is carried out entirely.
