Abstract
An electric connector safety choke plug capable of changing an initiating explosive device resistor comprises a connector, a printed plate jack assembly, a first printed plate, a second printed plate,a needle connector, a hole connector and the initiating explosive device resistor, wherein the front end of the printed plate jack assembled component is in abutting joint with the connector, and the tail end of the same is fixedly connected with the first printed plate; the needle connector and the hole connector are respectively fixed on the first printed plate and the second printed plate, and the initiating explosive device resistor is fixed on the second printed plate; and the first printed plate is in abutting joint with the second printed plate through the needle connector and the hole connector and connected with the second printed plate through a fastening piece so as to realize fixation and electric conduction. After the electric connector safety choke plug capable of changing t he initiating explosive device resistor is connected with an electric connector, when the initiating explosive device resistor is burned down, only the second printed plate needs to be disassembled tochange the initiating explosive device resistor, thereby the maintainability of the electric connector with the initiating explosive device resistor is enhanced, and the use cost of the same is reduc ed.
Description
Technical field
The present invention relates to a kind of electric connector safety plug, belong to dynamo-electric assembly technical field.
Background technology
Usually the way that connects priming system resistance at the tail end of electric connector be directly with resistance welded on the lead of band contact, connect a priming system resistance through lead at two hole interdigits of definition, last embedding silicon rubber protects with hood.The shortcoming of this structure is no any maintainability, and after priming system resistance burnt, whole connector was also and then scrapped.Cause sizable waste.
Summary of the invention
The objective of the invention is to:, a kind of electric connector safety plug of replaceable priming system resistance newly is provided to the defective that above-mentioned technology can not be keeped in repair.This structure can easily plug changes priming system resistance, and need not scrap whole electric connector.
Electric connector safety plug according to the invention comprises connector, printed board jack assembly, first printed board, second printed board, needle connector, hole connector and priming system resistance; Printed board jack assembly front end docks with connector; Tail end is fixedly connected with first printed board; Needle connector and hole connector are separately fixed in first and second printed boards; Priming system resistance is fixed in second printed board simultaneously, and first, second printed board realizes fixing and electrically conducting through the butt joint of its pin, hole connector.
Described printed board jack assembly afterbody is provided with the step of fixing first printed board.
Described first printed board and second printed board are provided with corresponding connecting hole, are locked through securing member.
Said safety plug connector place is provided with hood, and this hood is connected with connector locking through the connector screw thread.
After the priming system resistance welded is fixing, can be perpendicular to plane, second printed board place, also can be parallel or favour plane, second printed board place.
The invention has the beneficial effects as follows: after wherein priming system is burnt, change priming system resistance and just no longer need scrap whole electric connector, only need on the dismounting safety plug second printed board to change priming system resistance and get final product.

Embodiment
Fig. 1 is the structural representation of embodiment one; As shown in the figure; This safety plug is made up of connector 1, printed board jack assembly 2, first printed board 3, second printed board 6, needle connector 4, hole connector 5, protective cover 10, priming system resistance 9, and wherein printed board jack assembly 2 afterbodys are provided with step, and printed board jack assembly 2 afterbodys are provided with step 2a; Its front end docks with the hole of connector 1; First printed board 3 is welded at afterbody step 2a place, considers the structural strength of first printed board 3, and its Thickness Design is 2mm; The size of second printed board 6 is identical with first printed board 3 with thickness; Needle connector and hole connector are weldingly fixed on respectively in first and second printed boards; Priming system resistance also is weldingly fixed in second printed board simultaneously; Through the butt joint of pin, hole connector, realize first, second printed board electrically conducting, also can plug easily.Simultaneously for fixing second printed board 6; Center in first printed board 3 and second printed board 6 is provided with through hole respectively; During assembling; The bottom of first printed board 3 fixes first printed board 3 with nut 11 and packing ring with needle connector 4 after, again needle connector 4 is welded on above first printed board 3, butt hole connector 5 puts in place with needle connector 4 then; Pass in second printed board, 6 centre bores and the hole connector 5 the riveting pipe that is provided with screw 8 again and screw in the screw in the screw of inlaying of needle connector 4, thus second printed board 6 is fixing.Also can corresponding connecting hole be set, connect fixing, as shown in Figure 4 through lining 19 and screw 20 at first, second printed board edge.
Because priming system resistance 9 can produce high temperature usually when burning, and all can produce fifth wheel after burning.In order to prevent its destruction to printed board; Designed a protective cover 10 that utilizes epoxy plate machine-shaping; Purpose is that priming system resistance 9 and printed board are isolated; Can also hole connector 5 and needle connector 4 be protected simultaneously, this protective cover is fixed into integral body through the screw 7 and second printed board.
This safety plug also is provided with hood 18 simultaneously, realizes being locked of hood 18 and connector 1 through connector screw thread 1a, and is as shown in Figure 3.
After the priming system resistance welded is fixing, can be perpendicular to plane, second printed board place, as shown in Figure 1, also can be parallel or favour plane, second printed board place, thus the space of reduced height direction is as shown in Figure 5.
Safety plug of the present invention is connected with electric connector through connector 1; After wherein priming system resistance is burnt; Only need on the dismounting safety plug second printed board to change priming system resistance and get final product, thereby improve the maintainability of band priming system resistance electric connector, the reduction use cost.
