Invention Description (1) [Industrial Use Field] The present invention relates to detonators, especially for gas Detonator of the generator. [Previous Technology] Protective devices such as seatbelt pretensioners or airbags are known to protect passengers from impacts that occur during car conflicts. These protection devices' are used to protect a passenger by introducing a large amount of gas from a gas generator. In addition, the 'gas generator has an initiator and a gas generating agent.' When a conflict occurs, the initiator is ignited, and the gas generating agent is ignited and burned to generate a large amount of gas. The detonator used in the gas generator includes a plug made of airtight glass or ceramic, and a metal cup-shaped tube body containing a pyrophoric powder. The plug is inserted into the tube to seal the ignition. Construction of medicine. In addition, the open side of the pipe body is protected from water, air, or the like from entering the inside with a resin. This detonator has a bridge wire installed in the tube body and crimped to the gunpowder. The bridge wire is heated by the input current to cause the gunpowder to ignite. The previous detonators used airtight glass, ceramics, etc., which led to an increase in manufacturing costs. In recent years, the popularization of airbags has required the cost reduction of gas generators. Therefore, it is necessary to reduce the amount of wood in the initiator itself. As an example of a detonator that seeks to reduce costs, as shown in FIG. 5, a cup-shaped tube body 1 0 2 containing a pyrotechnic powder 103 is inserted into the tube body 102 and the pyrotechnic powder 103 is sealed. The plug 1 〇4 is made of plastic resin (please read the precautions on the back before filling out this page) 7 -Packing * ^ 1 I * 1 --- Order ·!-The standard paper size applies to Chinese National Standards < CNS) A4 specification (210 X 297 mm) -4-Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 46 93 4 0 a? ___ B7____ V. The description of the invention (2). The plug 104 is provided with a pair of conductive pins 105 and 106 penetrating the plug 104. Each of the conductive pins 105 and 106 protrudes into the tube, and its tip is electrically connected to the bridge wire 107. The bridge line 107 is covered with a second shaft 18. The aforementioned ignition ball 108 is in contact with the ignition powder 103. The aforementioned ignition ball 108 is composed of a thing having a high sensitivity for ignition, which is ignited by the heat generated by the bridge wire 1 ◦ 7 and the pyrotechnic substance 103 is ignited. The resin-made detonator is installed on the gas generator and receives a collision signal from the collision detector to input current. The input current is used to heat the bridge wire 107 and the ignition ball 108 is ignited. , And then made it angry. In addition, a flame or the like generated by the combustion of the pyrotechnic powder 103 is sprayed into the gas generator to ignite the gas generating agent. In the previous resin detonators, the ignition method was to use the bridge wire 10 7 to ignite the ignition ball 108, and then to ignite the pyrotechnic charge 103, so the bridge wire 1 0 7 and Lighter 1 0 3 Crimping method for direct contact. The crimping of the bridge wire 1 07 and the pyrotechnic powder 103 is to increase the contact area between the bridge wire 107 and the pyrophoric powder 103. In order to make the heat of the bridge cable 107 only make the pyrophoric powder sufficient 1 〇3 fire is necessary. This method of directly contacting the ignition powder with the bridge line has not previously been adopted for the following reasons: (1) Insertion of the resin-made pipe body 102 and the plug 1104 cannot achieve the bridge line 1 The surface pressure between 0 7 and the pyrotechnic powder 〇3 maintains a certain pressure contact for a long time.

Therefore, 'the previous resin-based detonator, in order to efficiently ignite the ignition powder i 〇3', it is necessary to cover the bridge wire 1 〇7 with the ignition ball 108. 'The use of this ignition ball 1 〇8 results in Rising manufacturing costs. The covering of the ignition ball 108 is usually performed by dipping the bridge wire 107 several times, thereby causing the manufacturing cost or the operating cost to remain high. In addition, it is necessary to continuously dip the bridge line 107. In addition, "Ignition Ball 108" is usually used to contain harmful heavy metals such as lead. From the viewpoint of environmental protection in recent years, it is gradually required not to use harmful substances. In this way, in recent years, it has been required to reduce the cost of gas generators for airbags, seatbelt pretensioners, and the like, and to use no harmful substances such as lead. The present invention seeks to reduce costs and provides an initiator that is beneficial to the environment. [Disclosure of Invention] The detonator of the present invention does not use a conventional resin detonator, but focuses on a crimping method in which the ignition powder is directly contacted with the bridge wire to achieve the purpose of reducing the manufacturing cost. In the detonator of the present invention, the tube body and the plug are formed of resin. In order to seal the ignition powder and the bridge wire in a crimped state, the constituent elements are as follows: a-part of the tube body and a part of the plug are embedded in each other Of the embedded structure. ---- I-： ----- install ------- * order · -------- brigade (please read the precautions on the back before filling this page) This paper size applies China National Standard (CNS) A4 specification (210 X 297 mm) -6- 469340 A7 B7 Printed by the consumer cooperation of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (4) Here, although the pipe and plug The resin can also be formed by directly contacting the fuse with the bridge wire, and the fuse can be ignited only by the heat of the bridge wire. In addition, the surface pressure between the ignition powder and the bridge line can be kept constant for a long time. Therefore, "the former resin initiator is not required, such as covering the bridge wire with an ignition ball", and therefore, it is possible to reduce the manufacturing cost. In addition, since no ignition ball containing harmful substances such as lead is required, a resin-made detonator with excellent environmental protection can be provided. In addition, powder or granules can be used as the pyrophoric powder. This can increase the contact area between the ignition powder and the bridge wire, and can easily ignite and burn. In addition, "in the case of a pyrophoric substance", a pyrophoric substance that uses only the heat of a bridge wire is used, for example, a pyrophoric substance having a pin component can be used. This makes it possible to make the ignition of the gunpowder more reliable by using only the heat of the bridge wire. By using the detonator of the present invention, that is, the former resin detonator is not needed, for example, the bridge wire is covered with the ignition ball, so the manufacturing cost can be reduced, and the pipe body can also be formed of metal. A metal pipe body generally causes an increase in cost compared with a resin pipe body. However, continuous production by press processing can suppress an increase in cost. In addition, the metal pipe body can reliably crimp the ignition powder and the bridge wire, and these surface pressures have a favorable point that can be reliably maintained for a long time. In this way, the metal pipe body is used to limit the deformation of the resin plug such as thermal expansion, and a structure for crimping the gunpowder and the bridge wire is formed. The gunpowder has a zirconium component and can be powdered or granular to ensure ignition Reliability.

Invention Description (10) Connectivity. In the cup body 62, a gas generating agent 61 which generates a gas by combustion is contained. At the bottom 6 2 b of the cup body 6 2, the gas generated by the combustion of the gas generating agent 61 1 is formed to the outside, for example, the gas release hole 6 2 a is released toward the seat belt pre-tensioning machine. The gas release hole 6 2 a is closed by a thin film-like explosion plate 6 3 such as aluminum. The opening 2 a side of the tube body 2 of the detonator 1, that is, the rib 20 side is fitted into the protrusion 55 of the supporting portion 5 2. The first step portion 59 of the temporary locking projection 5 4 of the protrusion 5 5 partially abuts the side end of the stage portion of the pipe body 2 and is fitted into the support portion 5 2. In this state, the detonator 1 and the cylindrical body 13 of the tube body 2 are positioned within the protrusion 55, and the side end of the tube body 2 and the flange portion of the plug 4 are sealed by the second step portion 58. Ring 5 7 snapped. The ribs 20 of the plug 4 penetrate through the protrusion 55 and protrude from the conductive pins 5 and 6 into the accommodation hole 56. Next, the tip of the temporary locking projection 54 is bent inward in the radial direction, and temporarily locked in order to make the outer stage portion 12 of the pipe body 2 be tightly closed. At this time, the length of the temporarily locking protrusion 54 is adjusted to be temporarily locked at the outer portion of the pipe body 2 by the outer portion of the second shaft body 18 of the plug 4. With such a structure, the temporary locking force can be applied toward the opening Π 2 a side of the tube body 2, and the effect of bending the plug 4 can be reduced. Therefore, the resin of the plug 4 is not peeled off from each of the conductive pins 5, 6 and a gap is generated, so that the intrusion of air or water can be minimized. In addition, temporarily locking the pipe body 2 can sufficiently ensure the pressure-connected state of the bridge wire 7 and the ignition powder 3.

Description of Invention (11) Borrowed Each of the conductive pins 5 and 6 is short-circuited by being engaged with the rib protrusion 22 of each rib 20. Then, the gas generator G is assembled by fitting the support portion 52 from the initiator 1 side into the cup body 6 2. The open side of the cup body 62 is fitted into the temporary locking projection 5 4 of the support portion 5 2 and is temporarily locked to the support portion body 53. This gas generator G inputs the current to each of the conductive pins 5 and 6 of the initiator 1 and uses the heat of the bridge wire 7 to ignite the ignition powder 3, and uses the flame from the initiator 1 to generate gas Agent 61 1 ignites a large amount of gas. Next, a large amount of gas generated in the cup body 62 raises the internal pressure of the cup body 6 2 to break the explosion plate 63 and is introduced into the seatbelt pretensioner through the gas release hole 6 2a. As a result, the safety belt pre-tensioner uses high-pressure gas to act to tighten the seat belt. In this way, when the detonator 1 of the present invention which can be manufactured inexpensively is used for the gas generator G, the manufacturing cost of the gas generator G itself can be reduced. In addition, although a resin-made detonator 1 is suitable for a gas generator, it can surely ignite the igniter 3 and the gas generator 61 can ignite. Therefore, the cost of the gas generator G can be reduced, and its reliability can be ensured. In addition, the detonator 1 can also be applied to a gas generator that inflates an airbag by utilizing the collision of a car. This gas generator includes things for a driver's seat, a passenger's seat, or a side collision. For those, a gas generating agent is burned to generate gas and inflate an airbag.
