Description

Technical Field

[0001] The invention relates to the field of electronic detonator detection, in particular to a temperature-resistant networking experimental device for an electronic detonator control module. Background Art

[0002] With the continuous development of the electronic digital detonator industry, electronic detonator modules are also constantly being updated. However, before each new electronic detonator module is officially used in electronic detonator production, it is first necessary to conduct various performance tests on the module, including temperature resistance networking experiments. To conduct a temperature resistance networking experiment on the electronic detonator module, it is necessary to first inject the code into the electronic detonator module and then rivet and weld it to the detonator leg wire. After that, it is placed in a high and low temperature chamber and charged with a detonator to form a network, and the voltage and current are recorded. Because the module needs to be riveted and welded multiple times, and the overall volume after welding is too large to be conveniently placed in a high and low temperature chamber, the temperature resistance networking experiment requires that each module be welded to the leg wire first, connected in parallel through the blasting busbar, and then placed in a high and low temperature chamber with a detonator to form a network. The network and charging voltage and current are observed. In addition, for different models of modules, the module needs to be removed and re-welded. The process is too cumbersome and greatly wastes R&D time. Summary of the Invention

[0003] The purpose of the present invention is to improve the efficiency of high and low temperature networking tests of electronic detonator control modules and to provide a temperature-resistant networking test fixture for electronic detonator modules.

[0004] The technical objectives of the present invention are achieved through the following technical solutions: An electronic detonator module temperature-resistant networking experimental fixture, characterized by comprising: A rectangular base is provided with a first groove on the front of the rectangular base, a second groove is provided in the first groove, a hinged cover is provided in the first groove, a group of accommodating grooves for accommodating the electronic detonator control module package are evenly distributed in the second groove, positioning strips are provided on both sides of each accommodating groove, and a positioning groove of the electronic detonator control module substrate is formed between two adjacent positioning strips, and a pair of probe holes are provided on the outside of each positioning groove in the second groove.

[0005] A third groove is provided on the back of the rectangular base, and a PCB board is connected to the third groove. A group of probe pairs are provided on the PCB board. Each probe pair passes through the probe hole and extends outward to the second groove on the front of the rectangular base. The probes on the same side of each probe pair are connected in series to the bus on one side, and the probes on the other side are connected in series to the bus on the other side. The buses on both sides are respectively connected to the bus output ends, and the bus output ends are connected to the terminal posts set on the side of the rectangular base through standard copper cables.

[0006] On the basis of the above technical solutions, there are the following further technical solutions: A pair of knob pressing plates matched with the assembling frame are respectively arranged on one side of the front of the rectangular base. Screws are arranged in the knob pressing plates to match with the rectangular base body.

[0007] When conducting a temperature-resistant networking test or other networking experiments, the present invention only needs to place the electronic detonator module into the furniture and clamp it, then connect the detonator to the terminal of the rectangular base body through the blasting busbar, and then operate the detonator to carry out the networking process. The probe on the clamp can directly contact the riveted terminal of the module, eliminating the riveting and welding process, and the overall volume is very small, which greatly improves the convenience of operation, simplifies the operation, and reduces the workload of designers.
