Abstract
The utility model discloses an after-powder-charge bridge wire protection sleeve. The after-powder-charge bridge wire protection sleeve comprises a housing and two pairs of metal sheets, wherein openings are formed at the two ends of the housing, the opening at one end of the housing is sleeved onto a circuit board and the opening at the other end of the housing is used for coating powder on a bridge wire; the two metal sheets in each pair are respectively located in the corresponding positions on the upper and lower inner surfaces of the housing; one end of each of the metal sheets is connected with the inner surface of the housing, and the other end of each of the metal sheets is provided with an inverted bayonet for clamping the circuit board; a hole corresponding to the inverted bayonet in position is formed on the circuit board; the metal sheets have elastic properties; the distance between the metal sheets in pair is smaller than the thickness of the circuit board; and when the housing is sleeved onto the circuit board, the pair of metal sheets are supported open, and the inverted bayonet is pushed into the hole in the circuit board.
Description
Technical field
The utility model relates to the priming system technical field, particularly a kind of back powder charge bridge silk protective sleeve.
Background technology
Digital electric detonator comprises shell 1, circuit board 2, bridge silk 3, payment to a porter 4, stopper 5 etc., and accompanying drawing 1 is seen in its position relation signal.Shell is generally metal shell; In circuit board is arranged; Be welded with holding circuit that control chip, electronic devices and components form, accumulator, firing circuit, auxiliary circuit etc. on the circuit board; Bridge silk, payment to a porter lay respectively at the two ends of circuit board, and on circuit board, pass stopper and extend to housing exterior by payment to a porter through wire bonds for the bridge silk.
Digital electric detonator production comprises multiple working procedure, after only the bridge wire bond connects completion, will pass through multiple operations such as detection, coating, assembling.The industrialization production process adopts the streamlined operation, can't avoid the transit link in the production process.Ability is filled in ignition, the ignition precision is limit, and it is very tiny easily broken that the bridge silk designs, and in links such as production and transportation, the careless slightly bridge silk that just possibly cause damages, and whole digital electric detonator can't detonate, and cause tremendous loss to production and explosive applications.
Summary of the invention
For solve the problem that the bridge silk damages easily in links such as production and transportation, the utility model provides a kind of back powder charge bridge silk protective sleeve, and said protective sleeve comprises shell and sheet metal; Said shell both ends open, an end opening is enclosed within on the circuit board, and other end opening is used for bridge silk coating; Said sheet metal has two pairs, and two sheet metals of every pair lay respectively at the shell correspondence position of inner surface up and down; Said sheet metal one end connects the inner surface of shell, and the other end has inverted gun thorn, is used to block circuit board; The hole of position corresponding to said inverted gun thorn arranged on the said circuit board; This sheet metal is flexible; Distance between the paired sheet metal is less than the thickness of circuit board, and when shell was enclosed within on the circuit board, paired sheet metal was strutted, and inverted gun thorn is pushed into the hole on the circuit board.
Porose on the end that said sheet metal is connected with shell, be used for fixing this sheet metal on the inner surface of shell.
Said sheet metal adopts the securing member that matees with the hole to be fixed on the inner surface of shell.
Said shell adopts plastic material.
Said shell vertical section is a hexagon.
Said sheet metal adopts steel matter.
Can know that by technique scheme the utility model in links such as detonator production and transport, effectively protects the bridge silk not to be damaged through put the bridge silk protective sleeve of powder charge after at the circuit board that is welded with the bridge silk one end.And when bridge silk coating, because protective sleeve away from an end opening of circuit board, so need not take off protective sleeve from circuit board, just can carry out the coating operation easily, safety, convenient.
Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.
