[0002] At present, electronic detonators are widely used in occasions such as tunnel excavation, danger removal blasting, demolition blasting, ore-rock separation, and open-pit blasting. The electronic detonator control module in the electronic detonator is the main initiation control part of the electronic detonator. The stability of the electronic detonator control module will directly affect the stability of the electronic detonator. The electronic detonator control 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 initiation control on the electronic detonator, a pair of control busbars need to be conductively connected to the electronic detonator control module. In the prior art, in order to realize the conductive connection between a pair of control busbars and the electronic detonator control 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 rotating and tightening the rotary joint with the rotary connector, the control busbar will be twisted. And after the rotary joint and the rotary connector are rotated and tightened, the twisted control busbar has a reverse twisting force on the rotary joint and the rotary connector, so that the rotary joint and the rotary connector are likely to become loose during the layout of the control busbar, and it is also easy for the connection between the control busbar and the rotary joint to become loose due to twisting of the control busbar, affecting the reliability of the connection between the control busbar and the rotary joint. Further, the connection component for realizing conductive connection is the key component for realizing the conductive connection between the control busbar and the electronic detonator control module. Further, the reliability of the existing connection structure for realizing the conductive connection between the control busbar and the electronic detonator control module on the electronic detonator also needs to be improved. Therefore, there is an urgent need for a connection component that is beneficial to avoiding the twisting of the control busbar caused by the conductive connection between the control busbar and the electronic detonator control module.

The second connection end and the second insertion stop end are respectively exposed outside the electrically insulating support body. The second connection end and the first connection end together form a pair of the pin wires, and a first insertion part is formed between the second insertion stop end and the first insertion stop end.
[0015] In this embodiment, the first connection end and the first insertion stop end are respectively connected to both ends of the first intermediate connection section, the second connection end and the second insertion stop end are respectively connected to both ends of the second intermediate connection section, the first intermediate connection section and the second intermediate connection section are connected to the electrically insulating support body, the second connection end and the first connection end together form a pair of lead wires, and a first insertion part is formed between the second insertion stop end and the first insertion stop end; this facilitates respectively connecting the second connection end and the first connection end to the control circuit board, thereby realizing the connection between the connection terminal block and the control circuit board; in addition, it is convenient to fixedly limit the first conductive lead and the second conductive lead through the electrically insulating support body, and when the second insertion part is inserted into the first insertion part, it can prevent the first insertion part from shifting in position or deforming, which may cause poor contact between the second insertion part and the first insertion part and reduce the electrical conductivity between the second insertion part and the first insertion part.

[0017] In this embodiment, an insertion slot is formed between the second insertion stop end and the first insertion stop end, and on both sides of the insertion tongue, there are respectively provided a first conductive contact part and a second conductive contact part that are electrically insulated from each other and are respectively opposite to the first insertion stop end and the second insertion stop end. This facilitates inserting the insertion tongue into the insertion slot, which is conducive to enabling the first conductive contact part and the second conductive contact part to be respectively in abutting contact with the first insertion stop end and the second insertion stop end and being respectively electrically connected; further, the second insertion part includes an insertion tongue, and on both sides of the insertion tongue, there are provided a first conductive contact part and a second conductive contact part that are electrically insulated from each other. The structure of the second insertion part is simple and is convenient to produce and obtain.
[0018] According to an embodiment of the present application, the insertion tongue includes a circuit board, the circuit board has a long strip-shaped structure, the first conductive contact part includes a first conductive metal layer, and the first conductive metal layer is disposed on one surface of the circuit board along the length direction of the circuit board; the second conductive contact part includes a second conductive metal layer, and the second conductive metal layer is disposed on the other surface of the circuit board along the length direction of the circuit board and is opposite to the first conductive metal layer.
[0019] The plugging tongue in this embodiment includes a circuit board, which facilitates the arrangement of a first conductive metal layer on one side of the circuit board to form a first conductive contact part, and the arrangement of a second conductive metal layer on the other side of the circuit board to form a second conductive contact part, facilitating the production of the plugging tongue and being conducive to the electrical insulation between the first conductive metal layer and the second conductive metal layer; further, the circuit board has a long strip structure, and the first conductive metal layer and the second conductive metal layer are respectively arranged along the length direction of the circuit board, which is conducive to increasing the contact areas between the first conductive metal layer and the second conductive metal layer and the first plugging abutting end and the second plugging abutting end respectively, thereby improving the conductivity between the first conductive metal layer and the first plugging abutting end and the conductivity between the second conductive metal layer and the second plugging abutting end.
[0020] According to an embodiment of the present application, the first plugging abutting end includes a first extending connection segment, a first deformation bending segment, a first inclined connection segment and a first abutting contact segment connected in sequence, and the first extending connection segment is connected to the first intermediate connection segment;
[0021] The second plugging abutting end includes a second extending connection segment, a second deformation bending segment, a second inclined connection segment and a second abutting contact segment connected in sequence, the second extending connection segment is connected to the second intermediate connection segment, the second deformation bending segment bends towards the first deformation bending segment, the second inclined connection segment is arranged opposite to the first inclined connection segment and inclines towards one side of the electrical insulation support body in an opposite direction, and a plugging guiding groove is defined between the second inclined connection segment and the first inclined connection segment; the second abutting contact segment is arranged opposite to the first abutting contact segment, and a first spacing is formed between the second abutting contact segment and the first abutting contact segment to form a conductive plug slot, and the plugging guiding groove communicates with the conductive plug slot to form the plugging slot, the plugging tongue is plugged into the conductive plug slot, and the first conductive contact part and the second conductive contact part are respectively in abutting contact with the first abutting contact segment and the second abutting contact segment and are respectively conductively connected;
[0022] And during the process of inserting the plugging tongue into the conductive plug slot, elastic deformation occurs on the side of the first deformation bending segment facing the first extending connection segment, and elastic deformation occurs on the side of the second deformation bending segment facing the second extending connection segment, so that the conductive plug slot expands outwards; when the plugging tongue is inserted into the conductive plug slot in place, the first deformation bending segment makes the first abutting contact segment elastically extrude the first conductive contact part based on elastic deformation, and the second deformation bending segment makes the second abutting contact segment elastically extrude the second conductive contact part based on elastic deformation.
[0023] In this embodiment, an insertion guiding groove is defined between the second inclined connecting section and the first inclined connecting section. During the process of inserting the insertion tongue into the conductive slot, the insertion guiding groove can guide the insertion direction of the insertion tongue, facilitating the accurate insertion of the insertion tongue into the conductive slot. Further, during the process of inserting the insertion tongue into the conductive slot, the first deformation and bending section generates elastic deformation toward the side of the first extended connecting section, and the second deformation and bending section generates elastic deformation toward the side of the second extended connecting section, causing the conductive slot to expand outward. When the insertion tongue is inserted into the conductive slot in place, the first deformation and bending section makes the first abutting contact section elastically squeeze the first conductive contact part based on elastic deformation, and the second deformation and bending section makes the second abutting contact section elastically squeeze the second conductive contact part based on elastic deformation, not only improving the conductivity between the first abutting contact section and the first conductive contact part and the conductivity between the second abutting contact section and the second conductive contact part, but also the first abutting contact section and the second abutting contact section can squeeze and clamp the insertion tongue, which is beneficial to improving the reliability of the insertion connection between the insertion tongue and the conductive slot.
[0024] According to an embodiment of the present application, the first insertion abutting end further includes:
[0025] An expansion constraint section one, one end of the expansion constraint section one is connected to the first abutting contact section, and the other end of the expansion constraint section one extends toward the first extended connecting section to form an extension end one;

[0027] An expansion constraint section two, one end of the expansion constraint section two is connected to the second abutting contact section, and the other end of the expansion constraint section two extends toward the second extended connecting section to form an extension end two;
[0028] And during the process of inserting the insertion tongue into the conductive slot, the maximum distance of the outward expansion of the conductive slot is equal to the sum of the distance between the end of the extension end one and the first extended connecting section and the distance between the end of the extension end two and the second extended connecting section, 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.
[0029] In this embodiment, an expansion constraint section one is connected to the abutting contact section one, and an expansion constraint section two is connected to the abutting contact section two. During the process of inserting the insertion tongue into the conductive slot, the deformation bending section one generates elastic deformation toward the side of the extending connection section one, and the deformation bending section two generates elastic deformation toward the side of the extending connection section two, causing the conductive slot to expand outward. When the end of the extending end one abuts against the extending connection section one and the end of the extending end two abuts against the extending connection section two, the conductive slot stops expanding outward. This is beneficial for restricting the deformation range of the deformation bending section one and the deformation bending section two, preventing the deformation bending section one and the deformation bending section two from being overly deformed and losing the elastic extrusion effect on the insertion tongue, and is conducive to ensuring that the abutting contact section one and the abutting contact section two have an elastic extrusion force on the insertion tongue inserted into the conductive slot, thereby improving the reliability of the insertion connection between the insertion tongue and the conductive slot.

[0080] In this embodiment, asFigure 1 , Figure 2 and Figure 5 As shown in Figure 5 , the plugging abutting end two is disposed opposite to the plugging abutting end one, and a plugging groove is formed between the plugging abutting end two and the plugging abutting end one. In this embodiment, the conductive contact part two is disposed on both sides of the plugging tongue 21 opposite to the conductive contact part one.

[0082] In this embodiment, as Figure 5 shown in Figure 5 , the plugging tongue 21 in this embodiment includes a circuit board, which facilitates the arrangement of the conductive metal layer one 211 on one surface of the circuit board to form the conductive contact part one, and the arrangement of 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 disposed 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 abutting end one and the plugging abutting end two respectively, thereby improving the conductivity between the conductive metal layer one 211 and the plugging abutting end one and the conductivity between the conductive metal layer two 212 and the plugging abutting end two.

[0084] In this embodiment, as Figure 5As 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 the 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 electrical 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.

[0085] 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.
[0086] An embodiment of the present application, as Figures 1 to 4 shown, a first plugging and abutting end includes a first extended connection section 113, a first deformation and bending section 114, a first inclined connection section 115, and a first abutting contact section 116 connected in sequence. The first extended connection section 113 is connected to the first intermediate connection section 112;
[0087] A second plugging and abutting end includes a second extended connection section 123, a second deformation and bending section 124, a second inclined connection section 125, and a second abutting contact section 126 connected in sequence. The second extended connection section 123 is connected to the second intermediate connection section 122. The second deformation and bending section 124 bends towards the first deformation and 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 electrical 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 abutting contact section 126 is arranged opposite to the first abutting contact section 116, and a first spacing is formed between the second abutting contact section 126 and the first abutting contact section 116 to form a conductive plug slot. The plugging guide groove and the conductive plug slot communicate to form a plugging slot. A plugging tongue 21 is inserted into the conductive plug slot. The first conductive contact part and the second conductive contact part respectively abut against and are electrically connected to the first abutting contact section 116 and the second abutting contact section 126;
[0088] 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 extension connection section 113, and the second deformation and bending section 124 generates elastic deformation toward the side of the second extension 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 contact 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 contact section 126 to elastically squeeze the second conductive contact portion based on the elastic deformation.
[0089] In this embodiment, as Figures 1 to 4 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 extension connection section 113, and the second deformation and bending section 124 generates elastic deformation toward the side of the second extension 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 contact 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 contact section 126 to elastically squeeze the second conductive contact portion based on the elastic deformation, not only improving the conductivity between the first abutting contact section 116 and the first conductive contact portion and improving the conductivity between the second abutting contact section 126 and the second conductive contact portion, but also the first abutting contact section 116 and the second abutting contact 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.
[0090] 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 are not subjected to the outward extrusion 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 contact section 116 and the second abutting contact section 126 are subjected to the outward extrusion force, the first deformation and bending section 114 generates elastic deformation toward the side of the first extension connection section 113, and the second deformation and bending section 124 generates elastic deformation toward the side of the second extension connection section 123, causing the conductive slot to expand outward and the opening of the conductive slot to increase.
[0091] In this embodiment, as Figures 1 to 4As shown in the figure, the first intermediate connection segment 112 in this embodiment is approximately in a Z-shaped bending structure bent upward, and the second intermediate connection segment 122 is approximately in a Z-shaped bending structure bent downward. An avoidance opening one 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, and an avoidance opening two 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 linear sheet 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 linear sheet structure and extends parallel to the first connection end 111, the second extended connection segment 123 is in a linear sheet 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.
[0092] An embodiment of the present application, as Figures 1 to 4 shown, the first plugging and abutting end further includes:
[0093] 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 towards the first extended connection segment 113 to form an extension end one;
[0094] The second plugging and abutting end further includes:
[0095] 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 towards the second extended connection segment 123 to form an extension end two;
[0096] And during the process of inserting the plugging tongue 21 into the conductive slot, the maximum distance of the outward expansion of the conductive slot is equal to the sum of the distance between the end of the extension end one and the first extended connection segment 113 and the distance between the end of the extension end two 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.
[0097] In this embodiment, as Figures 1 to 4As 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 extending connection section one 113, and the deformation bending section two 124 generates elastic deformation toward the side of the extending connection section two 123, causing the conductive slot to expand outward. When the end of the first extension end abuts against the extending connection section one 113 and the end of the second extension end abuts against the extending 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, thereby improving the reliability of the insertion connection between the insertion tongue 21 and the conductive slot.
[0098] In this embodiment, as Figures 1 to 4 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 extrusion force from the inside to the outside. The first extension end of the expansion constraint section one 117 moves closer to the extending connection section one 113, and the second extension end of the expansion constraint section two 127 moves closer to the extending connection section two 123. When the first extension end of the expansion constraint section one 117 abuts against the extending connection section one 113 and the second extension end of the expansion constraint section two 127 abuts against the extending connection section two 123, the conductive slot stops expanding outward.
[0099] Furthermore, as Figures 1 to 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 extending 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 extending connection section two 123.
