Referring to fig. 1 in conjunction with fig. 2, an initiator 100 is provided according to an embodiment of the present application. The initiator 100 is used to mate with a pin clamp 10 of an electronic detonator (not shown) to register the electronic detonator. The initiator 100 includes a housing 110, a terminal 120, and an activation portion 130.

The electronic detonator priming system includes an electronic detonator and a detonator 100. The electronic detonator mainly comprises an electronic integrated chip, an energy storage capacitor, an electronic ignition switch and a basic component of a related electric detonator. The electronic detonator needs to communicate bi-directionally with the initiator 100. And reading the built-in UID code in the electronic detonator integrated chip through the detonator 100 to trigger the electronic detonator to detonate.

The electronic detonator has a foot clip 10. Two leg wires (not shown) and two wire retaining tabs (not shown) are provided within the leg clip 10. The two leg wires are clamped in the leg wire clamp 10 through the wire clamping contact piece. When the electronic detonator is detonated, the contact of the wire contact is brought into contact with the trigger portion 130 of the initiator 100, thereby triggering the electronic detonator to detonate.

The terminal 120 is disposed on the housing 110 and located inside the housing 110. The number of the terminals 120 is two, which are a positive terminal and a negative terminal, respectively.

The trigger 130 is fixedly connected to the housing 110. One end of the trigger 130 is located in the housing 110, and the other end protrudes out of the surface of the housing 110.

Specifically, the number of the triggering portions 130 is two. Inside the case 110, a positive terminal and one triggering part 130 are connected to one set of output terminals of the circuit board of the initiator 100 and a negative terminal and the other triggering part 130 are connected to the other set of output terminals of the circuit board of the initiator 100 by wires, so that the initiator 100 can output signals through the two triggering parts 130 to trigger the electronic detonator to detonate.

The electronic detonator can be detonated by breaking the leg wire clamp 10 of the electronic detonator and then contacting the two wire clamping contact pieces on the inner side of the leg wire clamp 10 with the two triggering parts 130 respectively. Since the trigger part 130 is formed in a plate shape or a block shape, it is wear-resistant, not easily broken or damaged, and can have a large contact area with the card wire contact piece, and thus, it is well contacted with the card wire contact piece, thereby facilitating the operation at the time of registration.

In a large-scale blasting site, for example, when a large-scale blasting is performed on hundreds of electronic detonators, hundreds of electronic detonators need to be registered one by one, and with the initiator 100, the trigger part 130 is in a sheet or block shape, so that the initiator is resistant to abrasion, breakage and damage, and has good contact with a card wire contact, and the registration time of the electronic detonators can be greatly saved.

In one embodiment, the material of the trigger 130 is metal. The trigger piece is a metal piece or a metal block. The metal has good conductivity, thereby facilitating the contact of the trigger part 130 with the card wire contact.

In one embodiment, the material used for the trigger 130 is copper. Copper is low cost and has good electrical conductivity to facilitate the contact of the trigger 130 with the card wire contacts.

In one embodiment, the trigger 130 is integrally formed with the housing 110, thereby facilitating a secure connection between the trigger 130 and the housing 110. When large-scale registration of electronic detonators is carried out, the initiator 100 needs to register hundreds of electronic detonators one by one, and the trigger part 130 is reliably connected with the shell 110 and is not easy to fall off, so that each electronic detonator can be effectively registered, and the efficiency of registering the electronic detonators is improved.

In one embodiment, the number of the triggering portions 130 is two, and the two triggering portions 130 are disposed in a staggered manner in the thickness direction of the housing 110 so as to correspond to the positions of the card line contacts in the pin line clamp 10.

Referring to fig. 3 and 4, in an embodiment, a groove 101 is formed at one end of the housing 110, and one end of the trigger 130 extending out of the surface of the housing 110 is located in the groove 101. Since one end of the trigger part 130, which protrudes out of the surface of the casing 110, is located in the groove 101, the trigger part 130 is less likely to be struck when the initiator 100 drops or collides with another object, and is less likely to be damaged, thereby improving the reliability of the initiator 100.

Referring to fig. 1 and 4, in one embodiment, the initiator 100 further includes a positioning plate 140 disposed within the recess 101, the positioning plate 140 being adapted to fit into a positioning slot (not shown) of the terminal 10.

Specifically, a positioning plate 140 is disposed in the recess 101. The positioning plate 140 is fixedly connected with the inner wall of the recess 101. At the time of contact registration, the clip 10 is broken and the clip 10 is inserted into the groove 101, so that the card wire contact is brought into contact with the trigger 130, thereby detonating the electronic detonator. Because the positioning plate 140 is matched with the positioning groove on the pin wire clamp 10, when the pin wire clamp 10 is inserted into the groove 101, the positioning plate 140 is matched with the positioning groove on the pin wire clamp 10, so that the pin wire clamp 10 can be conveniently and accurately inserted into the corresponding position in the groove 101, and the wire clamping contact piece can be conveniently and accurately contacted with the triggering part 130.

In one embodiment, the number of the positioning plates 140 is at least two. The positioning plates 140 are respectively disposed at both sides of the triggering portion 130, so that the clip 10 can be positioned at both sides of the triggering portion 130, respectively, facilitating accurate insertion of the clip 10 into the corresponding position of the recess 101.

Another embodiment of the present application further provides an electronic detonator initiation system (not shown). The electronic detonator initiation system comprises an electronic detonator and the initiator 100 in any of the above embodiments. The electronic detonator includes a foot clip 10. Two leg wires and two wire clamping contact pieces are arranged in the leg wire clamp 10. The wire clamping contact pieces are connected with the leg wires and are in one-to-one correspondence.

In the electronic detonator priming system, the electronic detonator can be primed by breaking the leg wire clamp 10 of the electronic detonator and then contacting the two wire clamping contact pieces on the inner side of the leg wire clamp 10 with the two triggering parts 130 respectively. Since the trigger part 130 is formed in a plate shape or a block shape, it is wear-resistant, not easily broken or damaged, and can have a large contact area with the card wire contact piece, and thus, it is well contacted with the card wire contact piece, thereby facilitating the operation at the time of registration.
