Abstract

The present invention provides an interlocking pattern wire clamp structure, including a bottom cover, a pressure cover buckled on the bottom cover, a pressure seat arranged at either end of a connecting component between the bottom cover and the pressure cover, an elastic arm connected to the pressure seat, a crimping knob rotatably arranged on the pressure cover, and a transmission component arranged between the crimping knob and the elastic arm. In the direction of wire withdrawal, the elastic arm gradually moves away from the pressure seat, and when the crimping knob rotates, the transmission component can apply force to the side of the elastic arm away from the pressure seat along the wire withdrawal direction. The interlocking pattern wire clamp structure of the present invention constructs a plurality of first bite protrusions arranged along the wire axis on the side of the elastic arm facing the pressure seat. When the pressure of the front first bite protrusion is reduced to a preset value, the subsequent first bite protrusion is automatically crimped again to ensure the conductive performance. When the subsequent first bite protrusion is working, the front first bite protrusion is still crimped with a relatively small pressure to improve the conductive performance.

[0040] like Figure 1-Figure 12 As shown, the embodiment of the present invention provides an interlocking wire clamp structure, including: a bottom cover 11, a pressure cover 12 buckled on the bottom cover 11, a pressure seat 13 arranged at either end of a communication component 20 between the bottom cover 11 and the pressure cover 12, an elastic arm 14 connected to the pressure seat 13, a crimping knob 15 rotatably arranged on the pressure cover 12, and a transmission component arranged between the crimping knob 15 and the elastic arm 14, in the direction of drawing out the wire ( Figure 2 As shown by the middle arrow, the elastic arm 14 gradually moves away from the pressure seat 13, and a plurality of first engaging protrusions 141 arranged along the axis of the wire are constructed on the side of the elastic arm 14 facing the pressure seat 13. When the crimping knob 15 is rotated, the transmission assembly can apply force to the side of the elastic arm 14 away from the pressure seat 13 along the wire withdrawal direction.

[0041] In the present embodiment, the interlocking wire clamp structure comprises a bottom cover 11, a pressure cover 12 buckled on the bottom cover 11, a pressure seat 13 at either end of a connecting component 20 arranged between the bottom cover 11 and the pressure cover 12, an elastic arm 14 connected to the pressure seat 13, a crimping knob 15 rotatably arranged on the pressure cover 12, and a transmission component arranged between the crimping knob 15 and the elastic arm 14. In the direction of wire withdrawal, the elastic arm 14 gradually moves away from the pressure seat 13. A plurality of first engaging protrusions 141 arranged along the wire axis are constructed on one side of the elastic arm 14 facing the pressure seat 13. When the crimping knob 15 is rotated, the transmission component can apply force to the side of the elastic arm 14 away from the pressure seat 13 in the direction of wire withdrawal. In specific applications, by rotating the crimping knob 15, the crimping knob 15 drives the transmission component to apply force to the side of the elastic arm 14 away from the pressure seat 13 in the direction of wire withdrawal. Since the elastic arm 14 Gradually moving away from the pressure seat 13, the elastic arm 14 is constructed with a plurality of first bite protrusions 141 arranged along the axis of the wire on one side of the pressure seat 13. Therefore, the first first bite protrusion 141 in the direction of wire withdrawal and the pressure seat 13 bite the wire. However, after long-term use, the first first bite protrusion 141 and the pressure seat 13 in the direction of wire withdrawal are fatigued and the bite force is reduced. At this time, the force applied by the transmission component to the side of the elastic arm 14 away from the pressure seat 13 in the direction of wire withdrawal will press the elastic arm 14 downward, so that the second first bite protrusion 141 in the direction of wire withdrawal and the pressure seat 13 also bite the wire. It can be seen that the interlocking pattern wire clamp structure of this embodiment arranges a plurality of first bite protrusions 141 on the elastic arm 14. When the pressure of the front first bite protrusion 141 is reduced to a preset value, the subsequent first bite protrusion 141 is automatically crimped again to ensure the conductive performance. In the direction of wire extraction, the elastic arm 14 gradually moves away from the pressing seat 13, so that the preset value of each first bite protrusion 141 on the elastic arm 14 remains consistent. When the subsequent first bite protrusion 141 works, the front first bite protrusion 141 still presses with relatively small pressure to improve the conductive performance.

[0042] In some embodiments, the pressure seat 13 is located on the side of the elastic arm 14 away from the bottom cover 11, and the transmission assembly includes a pressure rod 161, two connecting plates 162 and two elastic members 163. The two connecting plates 162 are both connected to the crimping knob 15. The pressure rod 161 is arranged on the side of the elastic arm 14 away from the pressure seat 13. One end of the pressure rod 161 is connected to one of the two connecting plates 162 through one of the two elastic members 163, and the other end of the pressure rod 161 is connected to the other connecting plate 162 of the two connecting plates 162 through the other elastic member 163 of the two elastic members 163. When the crimping knob 15 is rotated, the two connecting plates 162 can be driven toward a direction away from the bottom cover 11. When the two connecting plates 162 are toward a direction away from the bottom cover 11, the two elastic members 163 can be driven to pull the pressure rod 161 to move along the direction of wire extraction.

[0043] In this embodiment, the pressure seat 13 is located on the side of the elastic arm 14 away from the bottom cover 11, that is, the pressure cover 12 is located on the side of the pressure seat 13 away from the elastic arm 14. The transmission assembly of this embodiment includes a pressure rod 161, two connecting plates 162 and two elastic members 163. The two connecting plates 162 are arranged in parallel. The two connecting plates 162 are both connected to the crimping knob 15. The pressure rod 161 is arranged on the side of the elastic arm 14 away from the pressure seat 13. One end of the pressure rod 161 is connected to one of the two connecting plates 162 through one of the two elastic members 163. 163 is connected, and the other end of the pressure rod 161 is connected to the other connecting plate 162 of the two connecting plates 162 through the other elastic member 163 of the two elastic members 163. When the crimping knob 15 is rotated, the two connecting plates 162 can be driven toward the direction away from the bottom cover 11. When the two connecting plates 162 are toward the direction away from the bottom cover 11, the two elastic members 163 can be driven to pull the pressure rod 161 to move in the direction of pulling out the wire, so that when the crimping knob 15 is rotated, the transmission component applies force to the side of the elastic arm 14 away from the pressure seat 13 along the direction of pulling out the wire.

[0044] In some embodiments, two guide grooves 111 extending away from the pressing cover 12 are provided on one side of the bottom cover 11 facing the pressing cover 12, the two guide grooves 111 are located on both sides of the elastic arm 14 and extend to the elastic arm 14, one of the two connecting plates 162 is inserted into one of the two guide grooves 111, and the other connecting plate 162 is inserted into the other guide groove 111 of the two guide grooves 111, and the moving direction of the two connecting plates 162 is limited, so that when the crimping knob 15 is rotated in one direction, the two connecting plates 162 are driven to move relative to the pressing cover 12 in a direction away from the bottom cover 11, and when the crimping knob 15 is rotated in another direction, the two connecting plates 162 are driven to move relative to the pressing cover 12 in a direction close to the bottom cover 11.

[0045] In some embodiments, two connecting plates 162 are arranged on both sides of the crimping knob 15, and the two connecting plates 162 are both provided with a first sliding groove 1621 parallel to the axis of the wire. Both sides of the crimping knob 15 are provided with an insert shaft 151, one of the two insert shafts 151 is inserted into one of the two first sliding grooves 1621, and the other of the two insert shafts 151 is inserted into the other first sliding groove 1621 of the two first sliding grooves 1621. When the crimping knob 15 rotates, the insert shaft 151 moves in the first sliding groove 1621, thereby driving the connecting plate 162 to move away from the bottom cover 11 or close to the bottom cover 11 relative to the pressing cover 12, thereby preventing the connecting plate 162 from getting stuck with the crimping knob 15.

[0046] In some embodiments, the connecting plate 162 is provided with a second sliding groove 1622 which gradually approaches the bottom cover 11 in the direction of the wire being pulled out, and a locking groove 1623 which is connected to the second sliding groove 1622 and is perpendicular to the axis of the wire. The end of the elastic member 163 away from the pressing rod 161 is slidably arranged in the second sliding groove 1622. Therefore, when the crimping knob 15 rotates to drive the two connecting plates 162 away from the bottom cover 11 relative to the pressing cover 12, the second sliding groove 1622 and the elastic member 163 are connected to each other. The sliding fit of the end of the elastic member 163 away from the pressure rod 161 can make the two elastic members 163 move in the direction of the wire withdrawal, thereby driving the pressure rod 161 to move along the wire withdrawal direction, so that the pressure rod 161 applies force to the side of the elastic arm 14 away from the pressure seat 13 along the wire withdrawal direction. The elastic member 163 is elastic. Since the locking groove 1623 is perpendicular to the axis of the wire, when the end of the elastic member 163 away from the pressure rod 161 slides into the locking groove 1623, the elastic member 1 The end of the elastic member 163 away from the pressure rod 161 will be locked in the locking groove 1623, so that the elastic member 163 can be in a stretched state. Since the elastic member 163 is elastic and in a stretched state, when one end of the elastic member 163 is locked in the locking groove 1623, the elastic member 163 will not pull the pressure rod 161 to move until all the first bite protrusions 141 on the elastic arm 14 are crimped on the wire. After long-term use, the first first bite protrusion 141 in the direction of pulling out the wire is 41 and the pressure seat 13 are fatigued, and the bite force is reduced. At this time, the elastic force of the elastic member 163 causes the pressure rod 161 to force the elastic arm 14 to press down, so that the second first bite protrusion 141 in the direction of the wire withdrawal and the pressure seat 13 also bite the wire, so that the interlocking pattern wire clamp structure is provided with multiple first bite protrusions 141 on the elastic arm 14. When the pressure of the front first bite protrusion 141 is reduced to a preset value, the subsequent first bite protrusion 141 automatically performs re-crimping to ensure the conductive performance. In the direction of the wire withdrawal, the elastic arm 14 gradually moves away from the pressure seat 13, so that the preset value of each first bite protrusion 141 on the elastic arm 14 remains consistent. When the subsequent first bite protrusion 141 is working, the front first bite protrusion 141 is still crimped with a relatively small pressure to improve the conductive performance.

[0047] The two guide grooves 111 are located on both sides of the elastic arm 14 and extend to the elastic arm 14 , thereby forming a channel so that one end of the elastic member 163 away from the pressure rod 161 can be disposed in the second sliding groove 1622 to prevent interference.

[0048] In some embodiments, the elastic member 163 includes a cylinder body 1631 having an opening at one end and a telescopic rod 1632 inserted into the cylinder body 1631; the cylinder body 1631 is connected to the pressure rod 161, and the side wall of the telescopic rod 1632 is constructed with a first sliding portion 16321 inserted into the second sliding groove 1622, so that the end of the elastic member 163 away from the pressure rod 161 can be slidably set in the second sliding groove 1622.

[0049] In some embodiments, the elastic member 163 includes a cylinder body 1631 having an opening at one end and a telescopic rod 1632 inserted into the cylinder body 1631; the telescopic rod 1632 is connected to the pressure rod 161, and the side wall of the cylinder body 1631 is constructed with a second sliding portion inserted into the second sliding groove 1622, so that the end of the elastic member 163 away from the pressure rod 161 can be slidably set in the second sliding groove 1622.

[0050] In some embodiments, a plurality of V-shaped snap-fit ​​grooves 142 arranged along the axis of the wire are constructed on one side of the elastic arm 14 away from the pressure seat 13, and the pressure rod 161 is clamped in any V-shaped snap-fit ​​groove 142, so that the pressure rod 161 and the side of the elastic arm 14 away from the pressure seat 13 are reliably abutted.

[0051] In some embodiments, the angular bisector of the V-shaped engaging groove 142 is parallel to the axis of the wire, and the angle of the V-shaped engaging groove 142 gradually increases in the direction of wire withdrawal. When the elastic arm 14 is gradually bent, the required bending force will become larger and larger. This structure can gradually enlarge the mouth of the V-shaped engaging groove 142, and the contact position between the pressure rod 161 and the wall of the V-shaped engaging groove 142 gradually moves away from the direction of wire withdrawal, so that the downward component of force becomes larger. This downward component of force can overcome the increased rebound force of the elastic arm 14 while keeping the preset value of each first bite protrusion 141 on the elastic arm 14 consistent.

[0052] In some embodiments, the connecting component 20 also includes an upper card plate 17 connected to the pressure seat 13, the upper card plate 17 is located on the side of the pressure rod 161 away from the elastic arm 14, the upper card plate 17 is constructed with two side plates 171 extending toward the pressure seat 13 and located on both sides of the pressure seat 13, and the two side plates 171 are provided with a third sliding groove 1711 parallel to the axis of the wire, the two connecting plates 162 are located on the outside of the two side plates 171, and the pressure rod 161 is inserted into the two third sliding grooves 1711, and the moving direction of the pressure rod 161 is limited by the two third sliding grooves 1711, so that when the two elastic members 163 pull the pressure rod 161, the pressure rod 161 moves along the withdrawal direction of the wire, ensuring that the pressure rod 161 applies force to the side of the elastic arm 14 away from the pressure seat 13 along the withdrawal direction of the wire.

[0053] In some embodiments, the ends of the two side plates 171 away from the upper clamping plate 17 are constructed with a hanging portion 1712 hung on the side of the pressure seat 13 away from the upper clamping plate 17, so as to prevent the pressure seat 13 from being deformed by pressure and causing the interlocking pattern wire clamp structure to fail, thereby improving the reliability of the interlocking pattern wire clamp structure.

[0054] In some embodiments, a through groove 172 is provided at the connection between the pressure seat 13 and the upper clamping plate 17, and a bending portion 143 is constructed at the end of the elastic arm 14 that is away from the direction of pulling out the wire. The bending portion 143 is hung on the side of the upper clamping plate 17 away from the pressure seat 13 via the through groove 172. The elastic arm 14 is hung on the side of the upper clamping plate 17 away from the pressure seat 13 via the bending portion 143 via the through groove 172, and the elastic arm 14 is connected to the pressure seat 13 of the connecting component 20.

[0055] In some embodiments, a first insertion hole 112 is formed on the bottom cover 11 , which is opposite to the space between the pressure seat 13 and the elastic arm 14 , and the wire is inserted between the pressure seat 13 and the elastic arm 14 through the first insertion hole 112 .

[0056] In some embodiments, two coaxial rotating shafts 152 are constructed on both sides of the crimping knob 15, and two second insertion holes 121 are opened on the pressure cover 12. The two rotating shafts 152 are plugged into the two second insertion holes 121 one by one, and the crimping knob 15 can be rotatably set on the pressure cover 12 through the cooperation between the rotating shafts 152 and the second insertion holes 121.

[0057] In the wire pulling-out direction, the insertion shaft 151 and the rotating shaft 152 are spaced apart in sequence, and the crimping knob 15 can be pressed down to move the two connecting plates 162 upward, thereby driving the two elastic components 163 to pull the pressure rod 161 to move along the wire pulling-out direction, so that when the crimping knob 15 is rotated, the transmission component applies force to the side of the elastic arm 14 away from the pressure seat 13 along the wire pulling-out direction.

[0058] In some embodiments, a plurality of second bite protrusions 131 arranged along the axis of the conductor are constructed on one side of the pressure seat 13 facing the elastic arm 14, and are staggered with the plurality of first bite protrusions 141. By staggering the second bite protrusions 131 and the first bite protrusions 141, the pressure seat 13 and the elastic arm 14 can bite the conductor more reliably, further improving the conductive performance.

[0059] In addition, the present invention can connect the wire group by combining multiple interlocking wire clamp structures, and the multiple interlocking wire clamp structures are locked to the pressing plate 19 by the corresponding locking pieces 18 to form a whole, such as Fig.12 As shown, multiple interlocking style wire clamp structures can be marked with 1, 2, 3, etc. for easy identification.

[0060] The interlocking wire clamp structure is symmetrically arranged on both sides of the locking member 18.
