The stability of the electronic detonator detonation module will directly affect the stability of the electronic detonator. The electronic detonator detonation module mainly includes a control circuit board and electronic components such as an integrated control chip, an ignition element, and an energy storage capacitor installed on the control circuit board.

[0003] Furthermore, in order to perform wired communication detonation control on the electronic detonator, a pair of control busbars need to be conductively connected to the electronic detonator detonation module. In the prior art, in order to achieve the conductive connection between a pair of control busbars and the electronic detonator detonation module, a rotary connector is usually used to conductively connect to the control circuit board, and then a rotary joint connected with the control busbar is threadedly connected to the rotary connector. However, during the process of screwing the rotary joint and the rotary connector tightly, the control busbar will be twisted. Moreover, after the rotary joint and the rotary connector are screwed tightly, the twisted control busbar has a rotational force on the rotary joint and the rotary connector, which is likely to cause the rotary joint and the rotary connector to become loose during the layout of the control busbar, and is likely to cause the connection between the control busbar and the rotary joint to become loose due to twisting, affecting the reliability of the connection between the control busbar and the rotary joint. Further, the reliability of the connection structure for realizing the conductive connection between the control busbar and the electronic detonator detonation module on the existing electronic detonator detonation module also needs to be improved. Therefore, there is an urgent need for an electronic detonator detonation module that is beneficial to preventing the control busbar from being twisted during the layout of the control busbar.

[0017] According to an embodiment of the present application, the second insertion abutting end is disposed opposite to the first insertion abutting end, and an insertion slot is formed between the second insertion abutting end and the first insertion abutting end; the second insertion portion includes an insertion tongue, and electrically insulated conductive contact portions one and two are respectively disposed on both sides of the insertion tongue opposite to the first insertion abutting end and the second insertion abutting end, the insertion tongue is inserted into the insertion slot, and the conductive contact portion one and the conductive contact portion two respectively abut against and are electrically connected to the first insertion abutting end and the second insertion abutting end.

[0018] In this embodiment, an insertion slot is formed between the second insertion abutting end and the first insertion abutting end, and electrically insulated conductive contact portions one and two are respectively disposed on both sides of the insertion tongue opposite to the first insertion abutting end and the second insertion abutting end, which is convenient to insert the insertion tongue into the insertion slot, and is beneficial to make the conductive contact portion one and the conductive contact portion two respectively abut against and be electrically connected to the first insertion abutting end and the second insertion abutting end; further, the second insertion portion includes an insertion tongue, and electrically insulated conductive contact portions one and two are disposed on both sides of the insertion tongue, and the structure of the second insertion portion is simple and convenient to produce and obtain.

The extended connection section two is connected to the intermediate connection section two. The deformation bending section two bends towards the deformation bending section one. The inclined connection section two is arranged opposite to the inclined connection section one and inclines towards one side of the electrical insulation support body. A plugging guide groove is defined between the inclined connection section two and the inclined connection section one.

The conductive contact part one and the conductive contact part two are respectively in abutting contact with the abutting contact section one and the abutting contact section two and are respectively conductively connected.

[0021] And during the process of inserting the plugging tongue into the conductive slot, an elastic deformation occurs on the side of the deformation bending section one facing the extended connection section one, and an elastic deformation occurs on the side of the deformation bending section two facing the extended connection section two, causing the conductive slot to expand outwards.

Further, during the process of inserting the plugging tongue into the conductive slot, an elastic deformation occurs on the side of the deformation bending section one facing the extended connection section one, and an elastic deformation occurs on the side of the deformation bending section two facing the extended connection section two, causing the conductive slot to expand outwards. When the plugging tongue is inserted into the conductive slot in place, the deformation bending section one elastically presses the conductive contact part one based on the elastic deformation, and the deformation bending section two elastically presses the conductive contact part two based on the elastic deformation, not only improving the conductivity between the abutting contact section one and the conductive contact part one, improving the conductivity between the abutting contact section two and the conductive contact part two, but also the abutting contact section one and the abutting contact section two can squeeze and clamp the plugging tongue, which is beneficial to improving the reliability of the plugging connection between the plugging tongue and the conductive slot.

The structure of the second insertion part is simple and convenient to produce.

[0079] In this embodiment, as Figures 1 to 4As shown, the plugging and abutting end two is arranged opposite to the plugging and abutting end one, and a plugging slot is formed between the plugging and abutting end two and the plugging and abutting end one. In this embodiment, the conductive contact part two is arranged on both sides of the plugging tongue 21 opposite to the conductive contact part one.

[0080] An embodiment of the present application, as Figure 2 and Figure 5 As shown, the plugging tongue 21 includes a circuit board, the circuit board has a long strip structure, the conductive contact part one includes a conductive metal layer one 211, and the conductive metal layer one 211 is arranged on one surface of the circuit board along the length direction of the circuit board; the conductive contact part two includes a conductive metal layer two 212, and the conductive metal layer two 212 is arranged on the other surface of the circuit board along the length direction of the circuit board and opposite to the conductive metal layer one 211.

[0081] In this embodiment, as Figure 2 and Figure 5 As shown, the plugging tongue 21 in this embodiment includes a circuit board, which is convenient for arranging the conductive metal layer one 211 on one surface of the circuit board to form the conductive contact part one, and arranging the conductive metal layer two 212 on the other surface of the circuit board to form the conductive contact part two, which is convenient for producing the plugging tongue 21 and is beneficial to the electrical insulation between the conductive metal layer one 211 and the conductive metal layer two 212; further, the circuit board has a long strip structure, and the conductive metal layer one 211 and the conductive metal layer two 212 are respectively arranged along the length direction of the circuit board, which is beneficial to increasing the contact area between the conductive metal layer one 211 and the conductive metal layer two 212 and the plugging and abutting end one and the plugging and abutting end two respectively, thereby improving the conductivity between the conductive metal layer one 211 and the plugging and abutting end one, and improving the conductivity between the conductive metal layer two 212 and the plugging and abutting end two.

[0082] Further, as Figure 2 and Figure 5 As shown, the plugging and abutting end one in this embodiment includes a stop contact section one 116, and the conductive metal layer one 211 is arranged opposite to the stop contact section one 116 on the plugging and abutting end one; the plugging and abutting end two in this embodiment includes a stop contact section two 126, and the conductive metal layer two 212 is arranged opposite to the stop contact section two 126 on the plugging and abutting end two; further, the conductive metal layer one 211 and the conductive metal layer two 212 in this embodiment are specifically conductive copper layers, and the conductive contact part one and the conductive contact part two can also be set into other conductive contact structures.

[0083] In this embodiment, as Figure 5 and Figure 12As shown, a first bus bar 22 is connected to one end of a first conductive contact part, and a second bus bar 23 is connected to one end of a second conductive contact part. The first bus bar 22 and the second bus bar 23 are connected to the same end of a circuit board to jointly form a pair of bus bars. The circuit board connected with the first bus bar 22 and the second bus bar 23 is placed into a potting injection cavity three of a potting injection mold three, and the placement posture of the circuit board is adjusted and limited. The potting injection mold three is used to pot the position to be potted of the circuit board connected with the first bus bar 22 and the second bus bar 23, so that an electric insulation support colloid is formed by wrapping the outer periphery of a bus bar connection end 41 and a length section of the first bus bar 22 and the second bus bar 23 close to the bus bar connection end 41. The electric insulation support colloid wraps the outer periphery of the bus bar connection end 41 and a length section of the first bus bar 22 and the second bus bar 23 close to the bus bar connection end 41, and seals and fixes the first bus bar 22 and the second bus bar 23 to the circuit board to obtain a socket 2. The electric insulation support colloid in this embodiment serves as a plugging support head 20, and the plugging support head 20 connected with the first bus bar 22 and the second bus bar 23 constitutes the socket 2 in this embodiment.

[0084] Further, the potting injection mold three in this embodiment can be designed according to the requirements of the injection molding process for the plugging support head 20. The specific structure of the potting injection mold three can refer to the existing potting injection mold for improvement and design, which will not be elaborated here.

[0085] An embodiment of the present application, as Figures 1 to 4 、 Figure 12 shown, a first plugging stop end includes a first extended connection section 113, a first deformation bending section 114, a first inclined connection section 115 and a first stop contact section 116 which are connected in sequence. The first extended connection section 113 is connected with a first intermediate connection section 112;

[0086] A second plugging stop end includes a second extended connection section 123, a second deformation bending section 124, a second inclined connection section 125 and a second stop contact section 126 which are connected in sequence. The second extended connection section 123 is connected with a second intermediate connection section 122. The second deformation bending section 124 bends towards the first deformation bending section 114. The second inclined connection section 125 is arranged opposite to the first inclined connection section 115 and inclines towards one side of the electric insulation support body 10. A plugging guide groove is defined between the second inclined connection section 125 and the first inclined connection section 115. The second stop contact section 126 is arranged opposite to the first stop contact section 116. A first distance is formed between the second stop contact section 126 and the first stop contact section 116 to form a conductive slot. The plugging guide groove is communicated with the conductive slot to form a plugging slot. A plugging tongue 21 is inserted into the conductive slot. The first conductive contact part and the second conductive contact part are respectively in stop contact with the first stop contact section 116 and the second stop contact section 126 and are respectively conductively connected;

[0087] During the process of inserting the insertion tongue 21 into the conductive slot, the first deformation and bending section 114 generates elastic deformation toward the side of the first extended connection section 113, and the second deformation and bending section 124 generates elastic deformation toward the side of the second extended connection section 123, causing the conductive slot to expand outward; when the insertion tongue 21 is inserted into the conductive slot in place, the first deformation and bending section 114 causes the first abutting and contacting section 116 to elastically squeeze the first conductive contact portion based on the elastic deformation, and the second deformation and bending section 124 causes the second abutting and contacting section 126 to elastically squeeze the second conductive contact portion based on the elastic deformation.

[0088] In this embodiment, as Figures 1 to 4 、 Figure 12 shown, a plugging guiding groove is defined between the second inclined connection section 125 and the first inclined connection section 115 in this embodiment. During the process of plugging the insertion tongue 21 into the conductive slot, the plugging guiding groove can guide the plugging direction of the insertion tongue 21, facilitating the accurate insertion of the insertion tongue 21 into the conductive slot; further, during the process of inserting the insertion tongue 21 into the conductive slot, the first deformation and bending section 114 generates elastic deformation toward the side of the first extended connection section 113, and the second deformation and bending section 124 generates elastic deformation toward the side of the second extended connection section 123, causing the conductive slot to expand outward; when the insertion tongue 21 is inserted into the conductive slot in place, the first deformation and bending section 114 causes the first abutting and contacting section 116 to elastically squeeze the first conductive contact portion based on the elastic deformation, and the second deformation and bending section 124 causes the second abutting and contacting section 126 to elastically squeeze the second conductive contact portion based on the elastic deformation, not only improving the conductivity between the first abutting and contacting section 116 and the first conductive contact portion, improving the conductivity between the second abutting and contacting section 126 and the second conductive contact portion, but also the first abutting and contacting section 116 and the second abutting and contacting section 126 can squeeze and clamp the insertion tongue 21, which is beneficial to improving the reliability of the plugging connection between the insertion tongue 21 and the conductive slot.

[0089] In this embodiment, as Figure 3 and Figure 4 shown, when the conductive slot is not plugged with the insertion tongue 21, the first deformation and bending section 114 and the second deformation and bending section 124 do not receive the outward squeezing force, the first deformation and bending section 114 and the second deformation and bending section 124 do not generate elastic deformation, and the conductive slot does not expand outward; further, as Figure 1 and Figure 2 shown, when the insertion tongue 21 is inserted into the conductive slot, the first abutting and contacting section 116 and the second abutting and contacting section 126 receive the outward squeezing force, the first deformation and bending section 114 generates elastic deformation toward the side of the first extended connection section 113, and the second deformation and bending section 124 generates elastic deformation toward the side of the second extended connection section 123, causing the conductive slot to expand outward and the opening of the conductive slot to increase.

[0090] In this embodiment, as Figure 3and Figure 4 As shown, in this embodiment, the first intermediate connection segment 112 is approximately in a Z-shaped bending structure bent upward, the second intermediate connection segment 122 is approximately in a Z-shaped bending structure bent downward. A first avoidance opening for avoiding the second intermediate connection segment 122 is provided on the first intermediate connection segment 112 opposite to the second intermediate connection segment 122. A second avoidance opening for avoiding the first intermediate connection segment 112 is provided on the second intermediate connection segment 122 opposite to the first intermediate connection segment 112. Further, the first connection end 111 and the second connection end 121 are in a straight sheet-like structure, and the first connection end 111 and the second connection end 121 are arranged opposite and flush in the left-right direction. Further, the first extended connection segment 113 is in a straight sheet-like structure and extends parallel to the first connection end 111, the second extended connection segment 123 is in a straight sheet-like structure and extends parallel to the second connection end 121, the first deformation bending segment 114 is connected to the first extended connection segment 113 and bends downward, and the second deformation bending segment 124 is connected to the second extended connection segment 123 and bends upward.

[0091] An embodiment of the present application, as Figures 1 to 4 、 Figure 12 shown, the first plugging and abutting end further includes:

[0092] The first expansion and constraint segment 117, one end of the first expansion and constraint segment 117 is connected to the first abutting contact segment 116, and the other end of the first expansion and constraint segment 117 extends toward the first extended connection segment 113 to form a first extension end;

[0093] The second plugging and abutting end further includes:

[0094] The second expansion and constraint segment 127, one end of the second expansion and constraint segment 127 is connected to the second abutting contact segment 126, and the other end of the second expansion and constraint segment 127 extends toward the second extended connection segment 123 to form a second extension end;

[0095] And during the process of inserting the plugging tongue 21 into the conductive slot, the maximum distance of outward expansion of the conductive slot is equal to the sum of the distance between the end of the first extension end and the first extended connection segment 113 and the distance between the end of the second extension end and the second extended connection segment 123, and the maximum distance is less than or equal to the thickness dimension between the first conductive contact part and the second conductive contact part.

[0096] In this embodiment, as Figures 1 to 4 、 Figure 12As shown in the figure, in this embodiment, an expansion constraint section one 117 is connected to the abutting contact section one 116, and an expansion constraint section two 127 is connected to the abutting contact section two 126. During the process of inserting the insertion tongue 21 into the conductive slot, the deformation bending section one 114 generates elastic deformation toward the side of the extended connection section one 113, and the deformation bending section two 124 generates elastic deformation toward the side of the extended connection section two 123, causing the conductive slot to expand outward. When the end of the first extension end abuts against the extended connection section one 113 and the end of the second extension end abuts against the extended connection section two 123, the conductive slot stops expanding outward. This is beneficial for restricting the deformation range of the deformation bending section one 114 and the deformation bending section two 124, preventing the deformation bending section one 114 and the deformation bending section two 124 from being overly deformed and losing the elastic extrusion effect on the insertion tongue 21, and is beneficial for ensuring that the abutting contact section one 116 and the abutting contact section two 126 have an elastic extrusion force on the insertion tongue 21 inserted into the conductive slot, improving the reliability of the insertion connection between the insertion tongue 21 and the conductive slot.

[0097] In this embodiment, as Figures 1 to 4 、 Figure 12 shown, during the process of inserting the second insertion part into the first insertion part, the abutting contact section one 116 and the abutting contact section two 126 are subjected to an outward extrusion force. The first extension end of the expansion constraint section one 117 moves closer to the extended connection section one 113, and the second extension end of the expansion constraint section two 127 moves closer to the extended connection section two 123. When the first extension end of the expansion constraint section one 117 abuts against the extended connection section one 113 and the second extension end of the expansion constraint section two 127 abuts against the extended connection section two 123, the conductive slot stops expanding outward.

[0098] Furthermore, as Figure 4 shown, the expansion constraint section one 117 in this embodiment is connected to the abutting contact section one 116 with an arc transition and extends upward and then bends to face the extended connection section one 113; in addition, the expansion constraint section two 127 is connected to the abutting contact section two 126 with an arc transition and extends downward and then bends to face the extended connection section two 123.

[0101] On the connection end 41, a receiving groove 422 is also provided opposite to the first plugging abutting end and the second plugging abutting end.

[0104] In this embodiment, as Figure 1 、 Figure 6 and Figure 12 shown, a plurality of electronic components are arranged on the control circuit board 30. The plurality of electronic components include an ignition component, a control chip, etc.; on one end of the control circuit board 30 far from a pair of pin wires, a first connection pin 311 and a second connection pin 312 are further connected.

[0108] In this embodiment, as Figure 5 , Figures 7 to 9 , Figure 12 shown, one inner side edge of the plugging limiting groove 411 is a limiting stop edge 413. A straight plate stop surface is formed on one side of the limiting stop edge 413. Correspondingly, a limiting recessed groove 2021 is provided on the plugging support head 20 corresponding to the limiting stop edge 413. After the plugging support head 20 is installed in the plugging limiting groove 411, the limiting stop edge 413 extends into the limiting recessed groove 2021 and limits the plugging support head 20.

[0109] In this embodiment, as Figure 12 shown, after the first plugging stop end and the second plugging stop end extend into the receiving groove 422, the outer side wall of the first extended connecting section 113 abuts against the upper inner wall of the receiving groove 422, and the outer side wall of the second extended connecting section 123 abuts against the lower inner wall of the receiving groove 422.

[0112] In this embodiment, as Figure 10 and Figure 12 shown, in this embodiment, the encapsulating colloid 5 is obtained through injection molding by an encapsulation process. The control module, the connection pin base 1, and the positioning base 4 are encapsulated and connected into one body by the encapsulating colloid 5, so that the encapsulating colloid 5, the control module, the connection pin base 1, and the positioning base 4 form a whole, improving the firmness and reliability of the connection between the connection pin base 1, the positioning base 4, and the control circuit board 30, which is beneficial to improving the quality of the electronic detonator detonation module; further, the electronic detonator detonation module in this embodiment can be installed in the housing 6 of the electronic detonator, facilitating the plugging of the second plugging portion and the first plugging portion at the blasting site to realize the conductive connection of a pair of busbars and the control circuit board 30; further, the encapsulating colloid 5 can also protect the multiple electronic components arranged on the control circuit board 30 and the connection pin base 1.

The mounting protrusion 101 is installed in the first mounting groove 421 and seals the first mounting groove 421. The potting body 5 wraps around the circumferential side of the potting connection part 102 and is fixedly connected to the potting connection part 102.

[0116] In this embodiment, as Figure 3 , Figure 6 and Figure 12 shown, the mounting protrusion 101 in this embodiment is installed in the first mounting groove 421 and seals the first mounting groove 421, which is beneficial for the potting body 5 formed by potting process to wrap around the outside of the potting connection part 102, improving the firmness of the potting connection of the potting body 5 to the electrical insulation support body 10; in addition, it is beneficial to prevent the colloid from entering the storage groove 422 during the potting injection process and affecting the first plugging stop end and the second plugging stop end stored in the storage groove 422.

[0117] An embodiment of the present application, as Figure 5 and Figure 12 shown, the plug socket 2 includes a plugging support head 20, a bus bar connection end 41 and a second plugging part are respectively connected to the plugging support head 20.
