Description

The built-in control module encapsulating protection of electric detonator structure

Technical field

The utility model relates to a kind of electric detonator structure, particularly the protection structure of the built-in electronic control module of electric detonator.

Background technology

The electronic control module that the electric detonator shell is built-in, be the critical component of controlling blasting cap initiation, and the reliability of these parts directly affects the reliability of electric detonator.

In order to ensure the reliability of electronic control module, just must improve its antistatic, moisture proof, anti-loosening ability as far as possible.

Prior art adopts the electronics solid seal glues such as heat-shrinkable T bush or the outer painting of employing epoxy resin to protect this module mostly, and plant produced efficiency is low, and the module protection intensity difference is shaped irregular, is unfavorable for the automated production of subsequent processing.

Summary of the invention

For the deficiencies in the prior art, the purpose of this utility model is: the built-in control module encapsulating of a kind of electric detonator protection structure is provided, improves the antistatic, moisture proof of electronic control module, anti-loosening ability.

The built-in control module encapsulating protection of a kind of electric detonator structure, it is characterized in that: comprise the sleeve pipe of electronic control module and a thin-walled, described electronic control module is placed in described sleeve pipe, between described electronic control module and sleeve pipe, is perfused with the insulation solid seal glue.

The built-in control module encapsulating protection of described electric detonator structure; wherein: described electronic control module has the control circuit board with delay chip and electric capacity; one end of described control circuit board is provided with point of amorce; the other end is provided with the payment to a porter pad; one end of described sleeve pipe is open; the other end has radially barricade, and the first end of the ignition charge of described electronic control module is from inserting in sleeve pipe the open end of described sleeve pipe, and the payment to a porter pad of electronic control module is exposed to the open end of sleeve pipe.

The built-in control module encapsulating protection of described electric detonator structure, wherein: be formed with groove between the side face of described radially barricade and described sleeve pipe.

The built-in control module encapsulating protection of described electric detonator structure, wherein: on described radially barricade, open a fire jetting hole.

The built-in control module encapsulating protection of described electric detonator structure, wherein: the point of amorce of described electronic control module is stuck in location in described fire jetting hole.

The built-in control module encapsulating protection of described electric detonator structure, wherein: described sleeve pipe is plastic material.

Compared with prior art; adopt the advantage the utlity model has of technique scheme to be: the utility model adopts sleeve pipe and insulation solid seal glue, can antistatic and moisture proof, and the point of amorce that protection is comparatively fragile; and sleeve pipe makes the outward appearance of product clean and tidy, be beneficial to assembling.

The accompanying drawing explanation

Fig. 1 is the composition structural representation of electronic control module;

Fig. 2 is the structural representation of the first sleeve pipe;

Fig. 3 is the structural representation that a kind of electronic control module that the utility model provides is connected with payment to a porter;

Fig. 4 is the structural representation of another kind of sleeve pipe;

Fig. 5 is the structural representation that another kind of electronic control module that the utility model provides is connected with payment to a porter.

The specific embodiment

At first, as shown in Figure 1, be the structural representation of electronic control module, it comprises that mainly an end of described control circuit board 3 is provided with point of amorce 4 with the control circuit board 3 of integrated chip 1 with electric capacity 2, the other end is provided with payment to a porter pad 5.When using, on payment to a porter pad 5, be welded with payment to a porter 6(such as Fig. 3, shown in Figure 5), time break is transferred to described control circuit board 3 by payment to a porter 6, and described chip 1 is subscribed the time delay of duration, then described control circuit board 3 passes to point of amorce 4 by initiation energy, realizes initiation control.

In order to protect this electronic control module, the sleeve pipe 8 that the utility model provides a kind of insulation material (as plastics) to make, as shown in Figure 2, an end of described sleeve pipe 8 is open, and the other end has radially barricade 81.

Then; as shown in Figure 3; by the point of amorce of electronic control module 4 one ends in the open end of described sleeve pipe 8, inserting sleeve pipe 8; and the pad of electronic control module is exposed to the open end of sleeve pipe 8; then at the interior perfusion insulation of sleeve pipe 8 solid seal glue (as epoxy resin); after glue is fixed, namely complete the encapsulating protection of electronic control module.Because the point of amorce mechanical strength is poor, also can select two kinds of fluid sealants, a kind of solidification intensity is low can be poured in advance, with the protection point of amorce, another kind of solidification intensity is high, after pour into the holding circuit plate.In the time of need to being assembled into electric detonator, the electronic control module of encapsulating protection can be connected with payment to a porter 6.

For the explosive force that makes point of amorce 4, enough destroy the radially barricade 81 of this sleeve pipe 8, radially barricade 81 thickness of described sleeve pipe 8 as thin as a wafer, general control arrives 0.1mm at 0.5mm, or be formed with groove between the side face of itself and described sleeve pipe 8, described groove makes the radially barricade 81 of described sleeve pipe 8 form an axially blast space, makes described radially barricade 81 be easy to be destroyed by explosive force.

Again as shown in Figure 4, in order further to improve the blast reliability of point of amorce 4, the utility model also provides another kind of sleeve pipe 8, it is compared with embodiment shown in Figure 2, on described radially barricade 81, to have opened a fire jetting hole 82, when the described sleeve pipe 8 of described electronic control module insertion was interior, the point of amorce 4 of described electronic control module just in time was stuck in the interior location of described fire jetting hole 82.

As shown in Figure 5, be the schematic diagram that electronic control module is connected with sleeve pipe 8 shown in Figure 4, it also means the schematic diagram that the built-in control module encapsulating protection of electric detonator structure is connected with payment to a porter 6.

Above explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, in the situation that do not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but within all falling into protection domain of the present utility model.
