Abstract
The utility model relates to a take socket of pre-charge needle, including the main needle mounting hole, with main needle mounting hole complex main needle, pre-charge needle mounting hole and with pre-charge mounting hole complex pre-charge needle, wherein, pre-charge needle through built-in connecting element with the main needle electricity is connected. The utility model embeds the connecting element of the pre-charging needle and the main needle in the socket, compared with the conventional socket, the utility model saves the external cable or PCB wiring, has simple structure and simplifies the assembly process; the production costs are further reduced due to the reduction of the associated cables and connecting elements.
Description
Technical field
The utility model relates to a kind of socket with the preliminary filling acusector.
Background technology
Power-supply system (as rectifier, inverter, UPS etc.) all requires power module can satisfy requirement at OIR.Plug on the module links to each other with socket in the system of working, thus the system that the online insertion of module is being worked.If the module pre-charge pin is not set, before output voltage was not set up as yet, the bus energy of system can recharge and enter the module output capacitance, made that busbar voltage is fallen, module output capacitance and outlet line be impaired, the export insurance pipe blows, and the accessory power outlet arcing burns out.
For fear of above-mentioned situation occurring, most of power modules have all designed pre-charge circuit on the module accessory power outlet.Fig. 1 is the circuit theory diagrams of module pre-charge.As shown in Figure 1, the plug on the module is about to link to each other with socket in the system of working.It is right that main pin 1a and 1b, 2a and 2b and preliminary filling acusector 3a and 3b constitute three set of contact respectively.Before three contacts were to equal access failure, the voltage at module output capacitance two ends reduced to zero.The contact of plug and socket to the process that is connected in because the contact of main pin is long to the stroke of 2a, 2b, contact contact the connection earlier to 3a, 3b to 1a, 1b with precharge.This moment, the precharge loop was connected, and gave module output capacitance current-limiting charge, guaranteed before main pin contact is connected 2a, 2b, and module output capacitance voltage equals or near busbar voltage.After contact is connected 2a, 2b, the system that the online insertion of module is being worked, pre-charge circuit is no longer worked.Thereby eliminated the risk of module at OIR.
At present, the preliminary filling acusector 3b of accessory power outlet is by realizing and being connected of system busbar from the socket external cable or by the PCB cabling.This structure more complicated has increased assembling difficulty and manufacturing cost.
The utility model content
The technical problems to be solved in the utility model is, the defective at the socket complex structure of existing band preliminary filling acusector provides a kind of preliminary filling acusector simple in structure, easy to assembly.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of socket with the preliminary filling acusector, comprise main pin installing hole, the main pin, the preliminary filling acusector installing hole that cooperate with described main pin installing hole and the preliminary filling acusector that cooperates with described precharge installing hole, wherein, described preliminary filling acusector is electrically connected with described main pin by built-in Connection Element.
In the socket of band preliminary filling acusector described in the utility model, described built-in Connection Element is arranged on the shell fragment on the described preliminary filling acusector.
In the socket of band preliminary filling acusector described in the utility model, be provided with the shell fragment mounting groove that extends to main pin installing hole one side from preliminary filling acusector installing hole in the described socket.
Implement the socket of band preliminary filling acusector of the present utility model, have following beneficial effect: the Connection Element of preliminary filling acusector and main pin is built in the socket, compares, saved external cable or PCB cabling with the socket of routine, simple in structure and simplified assembling procedure; Owing to reduced relevant cable and Connection Element, further reduced production cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the circuit theory diagrams of module pre-charge;
Fig. 2 is the partial sectional view of the socket of the utility model band preliminary filling acusector, the state when showing unassembled main pin and preliminary filling acusector;
Fig. 3 is the partial sectional view of the socket of the utility model band preliminary filling acusector, shows the state behind assembling main pin and the preliminary filling acusector;
Fig. 4 is the partial enlarged drawing of Fig. 3;
Fig. 5 is the profile of socket of the present utility model.
Embodiment
As Fig. 2--shown in Figure 5, in the socket 100 of the utility model band preliminary filling acusector, the preliminary filling acusector 3b that is provided with main pin installing hole 11, the main pin 2b that cooperates with main pin installing hole 11, preliminary filling acusector installing hole 12 and cooperates with precharge installing hole 12.Preliminary filling acusector 3b in the socket 100 is electrically connected with main pin 2b by built-in Connection Element.
Built-in Connection Element is arranged on the shell fragment 3c on the preliminary filling acusector 3b.In socket 100, be provided with the shell fragment mounting groove 13 that extends to main pin installing hole 11 1 sides from preliminary filling acusector installing hole 12.During assembling, in the preliminary filling acusector installing hole 12 in the preliminary filling acusector 3b insertion socket 100, shell fragment 3c stretches into main pin installing hole 11 along shell fragment mounting groove 13, and stretches out naturally in main pin installing hole 11.When main pin 2b was inserted main pin installing hole 11 and both and cooperatively interacts, shell fragment 3c deformed and closely contacts with main pin 2b.Thereby realized being connected of preliminary filling acusector 3b and main pin 2b.When module by in plug and socket 100 is connected, online insertion is being worked the system time, can realize the process of precharge and online insertion according to principle shown in Figure 1.Built-in Connection Element also can be arranged to lead etc.
In the socket of the present utility model, the Connection Element of preliminary filling acusector 3b and main pin 2b is built in the socket 100, compares, saved external cable or PCB cabling with the socket of routine, simple in structure and simplified assembling procedure; Owing to reduced relevant cable and Connection Element, further reduced production cost.
