Description

Technical Field

[0001] This invention relates to the field of electronic detonator technology, and in particular to a quick-connect, foolproof structure for electronic detonators. Background Technology

[0002] Electronic detonators, also known as digital electronic detonators, digital detonators, or industrial digital electronic detonators, are electric detonators that use an electronic control module to control the detonation process. In use, the electronic detonator is connected to the lead wire via a connecting structure, then the lead wire is connected to the busbar, and finally the busbar is connected to the detonating device. Because the installation environment for electronic detonators is relatively dark, and connection is inconvenient, it is also necessary to prevent accidents caused by incorrect connection ports. Therefore, precise alignment of the detonator's installation port is required during installation, which wastes more effort and time, and also affects installation efficiency. Summary of the Invention

[0003] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a quick-connection foolproof structure for electronic detonators, which can prevent incorrect connection of the connection ports during docking, thereby improving the installation efficiency and safety of electronic detonators.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick-connection foolproof structure for an electronic detonator includes a connecting assembly and an electronic detonator. One end of the electronic detonator has a male detonator socket, and the end face of the male detonator socket has a first electrical connector. One end of the connecting assembly has a first slot for connecting to the male detonator socket. The outer wall of the male detonator socket and the inner wall of the first slot have matching foolproof protrusions and grooves, respectively. The first slot contains a second electrical connector for connecting to the first electrical connector. The connecting assembly contains connecting leads for connecting to the second electrical connector. A sealing ring is provided between the first slot and the male detonator socket. The first slot contains locking teeth to prevent the male detonator socket from sliding out of the first slot. During installation, the electronic detonator is inserted into the connecting assembly. At this time, the first and second electrical connectors are electrically connected, the locking teeth abut against the male detonator socket, and the sealing ring tightly clamps between the male detonator socket and the first slot.

[0006] As a preferred embodiment, the anti-fouling protrusion is rectangular, conical, semi-circular, cylindrical, trapezoidal, or irregular in shape.

[0007] As a preferred embodiment, the connection assembly includes a wire end connector and an adapter that is fitted and connected to the wire end connector. The first slot is disposed inside the adapter, and the second electrical connector is disposed at one end of the wire end connector near the adapter. The adapter has a second slot at the end away from the opening of the first slot for the second electrical connector to be inserted into. The first slot and the second slot are in communication.

[0008] As a preferred embodiment, the adapter includes a first adapter and a second adapter. The second adapter includes a connecting post extending axially along a first slot. The first slot penetrates the upper and lower end faces of the second adapter. A buckle is provided around the connecting post. The first adapter has a first receiving groove corresponding to the connecting post. A slot corresponding to the buckle is provided on the side wall of the first receiving groove. The slot penetrates the side wall of the first adapter. During assembly, the connecting post is embedded in the receiving groove, and the buckle is engaged in the slot.

[0009] As a preferred embodiment, there are multiple locking teeth arranged in a ring. The roots of the locking teeth are integrally connected by a circular ring. The locking teeth extend obliquely upward from the inner sidewall edge of the circular ring towards the center of the circular ring. The second adapter has a mounting groove for assembling the circular ring at one end away from the opening of the first slot. The diameter of the mounting groove is larger than the diameter of the first slot. The bottom surface of the mounting groove and the sidewall of the first slot form a first stepped surface for supporting the circular ring.

[0010] As a preferred embodiment, the second slot has a second receiving groove for installing a sealing ring at one end near the first receiving groove. The first receiving groove is connected to the second receiving groove. The diameter of the second receiving groove is larger than that of the second slot. The bottom surface of the second receiving groove and the side wall of the second slot form a second stepped surface. During assembly, the sealing ring is clamped between the second stepped surface and the end face of the second adapter.

[0011] As a preferred embodiment, the diameter of the first receiving groove is larger than the diameter of the second receiving groove, the bottom surface of the first receiving groove and the side wall of the second receiving groove form a third stepped surface, a gasket is provided in the first receiving groove, and the inner diameter of the gasket is smaller than the diameter of the second receiving groove; during assembly, the gasket is clamped between the third stepped surface and the end face of the second adapter, and the sealing ring is clamped between the second stepped surface and the gasket.

[0012] As a preferred embodiment, the end of the wire connector that connects to the adapter has a protruding male connector, and the end of the adapter near the wire connector has a female connector corresponding to the male connector. The second electrical connector is located on the male connector. During assembly, the male connector is embedded in the female connector.

[0013] As a preferred embodiment, the sealing ring is molded from a soft colloid.

[0014] As a preferred embodiment, the first electrical connector is a terminal and the second electrical connector is a port; during installation, the electronic detonator is electrically connected to the connecting lead by inserting the terminal into the port.

[0015] Compared with the prior art, the present invention has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, by providing matching anti-foolproof protrusions and anti-foolproof grooves on the outer wall of the detonator male socket and the inner side wall of the first slot respectively, blind insertion can be achieved when connecting electronic detonators, improving installation efficiency and preventing installation errors; at the same time, a sealing ring is provided between the first slot and the detonator male socket to prevent water from entering at the electrical connection between the electronic detonator and the connecting assembly, causing a short circuit and improving the safety of the electronic detonator; and a retaining tooth is provided in the first slot to prevent the detonator male socket from sliding out of the first slot, preventing the electronic detonator from shaking or falling off due to external force after being connected to the connecting assembly, thus avoiding the electronic detonator failing to detonate as required, thereby reducing the explosion effect; by setting the connecting assembly into a multi-segment nested structure, the connecting assembly is convenient and quick to manufacture and install, improving production efficiency.
