Description

Technical Field

[0001] This utility model relates to the field of electronic detonator technology, specifically to an electronic detonator lead wire device. Background Technology

[0002] Electronic detonators, also known as digital electronic detonators, digital detonators, or industrial digital electronic detonators, are electric detonators that use electronic control modules to control the detonation process.

[0003] An electronic detonator consists of a detonator housing and, sequentially within the housing, lead wires, an electronic control module, an ignition charge, a main charge, and an initiating charge. The lead wires are used to transmit the detonation signal and need to be connected to external lead wires. When multiple detonators are used together, they need to be connected one by one. During use, the detonator that detonates first will pull on the lead wires, often causing the lead wires of subsequent detonators to detach, preventing them from detonating and creating a safety hazard that requires manual intervention and needs improvement.

[0008] As an improvement, the inner side of the first housing is provided with a first protrusion, and the outer side of the second housing is provided with a second protrusion that engages with the first protrusion.

[0009] As an improvement, the housing is threadedly connected to the cover.

[0010] As an improvement, the lead wire fixing device includes a conical cylinder that mates with the housing, and one end of the conical cylinder near the housing is provided with a ring that mates with the cover for positioning.

[0011] As an improvement, the conical cylinder has several notches evenly distributed on the inner side of the end near the ring.

[0013] (III) Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1. The housing is formed by the engagement of a first housing and a second housing, which facilitates the installation of the control chip;

[0016] 2. The opening of the housing is provided with a lead wire fixing device and a cover. The cover can fix the lead wire fixing device to the housing. The cover will squeeze the lead wire device, thereby squeezing and fixing the lead wire inside the lead wire fixing device.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature. Example

[0029] Combined with appendix Figure 1-5 An electronic detonator lead wire device includes a housing 1, which is composed of a first housing 2 and a second housing 3 that interlock with each other. A lead wire fixing device 4 is provided at the opening of the housing 1. A cover 5 is sleeved on the outside of the lead wire fixing device 4, which is squeezed and fixedly connected to the housing 1.

[0030] The inner side of the first housing 2 is provided with a first protrusion 6, and the outer side of the second housing 3 is provided with a second protrusion 7 that engages with the first protrusion 6.

[0031] The first protrusion 6 on the first housing 2 and the second protrusion 7 on the second housing 3 engage with each other, which facilitates the fixing of the first housing 2 and the second housing 3 and also facilitates the installation of the control chip. The cover 5 can fix the first housing 2 and the second housing 3 together. The cover 5 will squeeze the lead wire fixing device 4, and the lead wire fixing device 4 will squeeze the lead wires inside it, making the lead wires more firmly fixed.

[0032] The housing 1 is threadedly connected to the cover 5, which facilitates the installation of the housing 1 and the cover 5.

[0033] The lead wire fixing device 4 includes a conical cylinder 8 that cooperates with the housing 1. The end of the conical cylinder 8 near the housing 1 is provided with a ring 9 that cooperates with the cover 5 for positioning.

[0034] The conical cylinder 8 has several notches 10 evenly distributed on the inner side of the end near the ring 9.
