Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to solve the above-mentioned problems, the present invention provides a terminal block, referring to fig. 1-12 and 14, the leveling structure mainly includes a housing 1, a plug connector 2, a clamping knife 3, a mounting cavity 4 and a connecting spring 5, the housing 1 includes a first block 11 and a second block 12, the mounting cavities 4 are arranged in the first block 11 and the second block 12, and the two mounting cavities 4 are arranged in a central symmetry manner; the rear end of the clamping knife 3 is arranged in the mounting cavity 4, the front end of the clamping knife 3 is arranged in the inserting cavity arranged in front of the mounting cavity 4, and the inserting cavity is communicated with the outside, so that the lead 9 can be inserted into the inserting cavity from the side surface of the inserting cavity; the front end of the clamping knife 3 is provided with an arc-shaped cutting edge, and the plug connector 2 is inserted into the upper port of the plug cavity and presses down the lead 9, so that the lead 9 is connected and communicated with the front end edge of the clamping knife 3; the clamping knife 3 is in sliding conduction with the connecting elastic piece 5, so that the connecting elastic piece 5 can connect and conduct the wires 9 in the first block 11 and the second block 12.
The housing 1 may be divided into two parts, i.e. a first block 11 and a second block 12, for connecting the wires 9 to be connected respectively, the first block 11 and the second block 12 may be disposed in a central symmetry manner, and the structure in the first block 11 and the structure in the second block 12 are also in a central symmetry manner, as shown in fig. 2 and 9.
The housing 1 further comprises a bottom plate 13, and the bottom plate 13 is used for carrying structures and devices in the two blocks. The bottom plate 13 can be provided with arc-shaped depressions at positions corresponding to the plugging cavities so as to adapt to the wires 9 with different thicknesses. It can be understood that the wires 9 with different thicknesses refer to not only the wire core diameter, but also the thickness of the outer cladding of the wire core, and specifically whether the clearance between the clamping knife 3 and the wire core should satisfy the requirement that the clamping knife 3 and the wire core realize circular cutting conduction is suitable for the purpose that the clamping knife 3 can complete circular cutting conduction with the wire core.
Taking the first block 11 as an example for illustration, the inside of the shell 1 is provided with a mounting cavity 4, the rear end structure of the clamping knife 3 is arranged in the mounting cavity 4, the front end of the clamping knife 3 is arranged in the inserting cavity, the front end of the clamping knife 3 is provided with a cutting edge, and the wire 9 can be cut in a short-section mode, so that the wire 9 and the clamping knife 3 can be clamped and conducted.
The front section of the clamping knife 3 comprises a top edge 31 and a knife head 32, the top edge 31 is located above the knife head 32, the top edge 31 is used for conducting short-section circular cutting on the conducting wire 9, and the knife head 32 is used for conducting clamping connection and conducting on the conducting wire 9.
Specifically, the top blade 31 includes a horizontal blade and an arc-shaped blade, hereinafter referred to as a horizontal blade and an arc-shaped blade. The horizontal edge is located behind the arcuate edge, and both the horizontal edge and the arcuate edge are located above the cutter head 32. The front end of the cutter head 32 is also provided with a cutting edge, the front end cutting edge of the cutter head is positioned at the forefront end of the whole clamping cutter 3, the front end cutting edge is called as a front end cutting edge for short, and the whole direction of the front end cutting edge is a vertical direction.
When the arc-shaped blade and the front end blade are arranged, the arc-shaped blade and the front end blade can be in smooth transition connection, so that the blade of the clamping knife 3 can form an approximately integrated blade, and the lead 9 can be in smooth transition.
The rear section of the clamping knife 3 comprises a sliding block 33 and a tail cone 34, and the sliding block 33 is positioned behind the region of the knife head 32 and is arranged at two sides of the clamping knife 3; the tail cone 34 is arranged in the middle of the tail break of the clamping knife 3. The mounting cavity 4 comprises a slideway cavity and a telescopic cavity, the telescopic cavity is positioned at the front end of the slideway cavity and is communicated with the inserting cavity, a spring 41 is arranged in the telescopic cavity, a fixed column is arranged on the bottom wall of the telescopic cavity and is used for fixing one end of the spring 41, and the other end of the spring 41 is in butt joint and fixed to the tail cone 34; slide ways 42 are symmetrically arranged on two side walls of the slide way cavity, the sliding block 33 can slide in the slide ways 42, and the length of the slide ways 42 is the telescopic moving range of the clamping knife 3.
The spring 41 is always in a compressed state, so that the abutting effect of the clamping knife 3 on the lead 9 is stable. Further, when the arc-shaped blade of the clamping knife 3 is used for conducting circular cutting on the conducting wire 9, the requirement for external force for pushing the clamping knife 3 to slide backwards is large, after external force for pressing the conducting wire 9 is decomposed again, the sliding condition of the clamping knife 3 is not easy to be achieved, and in the circular cutting process, the arc-shaped blade can conduct stable circular cutting on the conducting wire 9.
When the height of the lead 9 is reduced to the tail end of the arc-shaped blade, the lead 9 continuously descends to transactionally push the clamping knife 3 to slide backwards, so that the abutting pressure between the front end blade and the wire core of the lead 9 is increased, and the stable circular cutting is conducted.
It will be appreciated that the sliding blocks 33 and the sliding ways 42 may be provided in a plurality of groups in cooperation to stabilize the sliding effect, so that the clamping knife 3 can stably realize telescopic sliding. The diameter of the inner cavity of the spring 41 should be larger than the height of the tail cone 34, but the outer diameter of the spring 41 should be smaller than the height of the tail end of the clamping knife 3, so that the elastic force of the spring 41 can be completely converted to the clamping knife 3.
It can be understood that the top edge 31 and the cutter head 32 can be made of different materials, and based on the cutting function requirement of the top edge 31, the top edge can be made of a material with higher hardness to form a cutting edge, such as steel; based on the abutting and conducting function requirements of the cutter head 32, materials with good electric conductivity can be used for coating to form a conducting blade, such as copper, and an electroplating mode can be used for coating. Further, the wrapping area of the cutter head 32 is limited, and the sliding contact and conduction with the sliding contact end of the connecting spring piece 5 can be kept all the time. If the sliding connection end is in sliding connection with the blade part of the cutter head 32, the elasticity is always changed, and the sliding connection is easy to be conducted unstably, so that the sliding connection conduction position is preferably the middle and rear section of the cutter head 32, the elasticity change of the sliding connection end is basically consistent, and the sliding connection conduction is relatively stable.
It will be appreciated that the horizontal edge is a transition edge and is hardly involved in the circular cutting of the wire 9. The arc-shaped blade is the main blade area of the circular cutting stage of the lead 9. The front edge is not involved in the circular cutting of the wire 9, and only the cutting groove diameter formed by the circular-cut wire 9 is clamped and connected with the wire core of the wire 9.
In the embodiment of the invention, the elastic sliding piece connected with the elastic piece 5 is fixed at the front end of the installation cavity 4 at the side of the clamping knife 3 far away from the shell 1, and the sliding connection end of the elastic sliding piece is in sliding connection with the knife head 32, and it can be understood that when the clamping knife 3 slides in a telescopic manner, the sliding connection end of the elastic sliding piece is always in the region of the knife head 32, namely, the sliding connection end is always in sliding connection and conduction with the copper plating region. Further, a front end of the mounting cavity 4 and a side of the clamping knife 3 close to the shell 1 are provided with a blocking block 62 for correcting/blocking the basic posture and position of the clamping knife 3. A gap is provided between the stopper 62 and the housing 1 to accommodate the attachment of the sheath 91.
In the embodiment of the invention, the connecting spring plate 5 is in sliding connection and conduction with the tool bit 32 of the clamping tool 3. The connecting spring piece 5 can directly conduct the lead 9 of the first block 11 and the second block 12; the connection spring 5 may also be provided with a control switch for controlling the connection/disconnection of the conductive wire 9 between the first block 11 and the second block 12, as follows:

The plug connector 2 comprises an outer plug board 21 and an inner plug board 22, wherein the outer plug board 21 is used for plugging a plug cavity on the side wall of the plugging shell 1, and the inner plug board 22 is used for plugging an inner cavity and an upper port of the plug cavity of the plugging shell 1.
A lining board slit 25 is arranged between the lower end of the outer inserting board 21 and the lower end of the inner inserting piece 22, and the lining board slit 25 is used for clamping and installing a sheath 91 sleeved outside the lead 9; a deflector rod 7 is arranged on the side wall above the clamping knife 3 and used for clamping the inner insert 22; the opposite side of the clamping knife 3 is provided with a baffle 6 for stopping the lead 9; so that the wire 9 is always positioned in the socket cavity when the plug connector 2 presses down the wire 9.
Specifically, the sheath 91 includes an inner liner 911, an outer liner 912, and a sleeve 913, wherein the outer liner 912 and the inner liner 911 are fixedly connected to the outer wall of the outer end of the sleeve 913, the outer liner 912 is located outside the inner liner 911, and the space between the inner liner 911 and the outer liner 912 is not smaller than the thickness of the outer insert 21; the wire 9 is capable of passing within the cannula 913. The position of the lining board 911 facing the bottom plate 13 is provided with a flat cut notch, which facilitates the installation of the sheath 91. The thickness of the external insertion plate 21 is substantially identical to that of the housing 1, facilitating the installation of the sheath 91.
Specifically, the driving lever 7 further comprises a driving block 71, a clamping piece 72 and an elastic plate 73, the upper surface of the shell 1 is provided with a driving groove 14, the driving block 71 is horizontally arranged in the driving groove 14, the driving block 71 is connected with the upper end of the elastic plate 73, and the lower section of the elastic plate 73 is obliquely fixedly connected below the side wall of the plug-in cavity.
The extension type clamping groove 23 is formed in the side wall of the inner plug 22, the clamping piece 72 is arranged on the outer side of the middle of the upper section of the elastic plate 73, when the plug connector 2 is inserted into the plug cavity downwards and the clamping piece 72 and the clamping groove 23 are buckled, the inner plug 22 in the buckling state can continuously downwards press the lead 9, the leads 9 with different thickness can be downwards pressed below the limiting plate 61, the clamping effect of the clamping groove 23 and the clamping piece 72 is prolonged to a certain extent, the plug-in allowance of the inner plug 22 is increased, and the pressing range is enlarged.
When the buckle between the clamping piece 72 and the clamping groove 23 needs to be released, the poking block 71 is pushed backwards, so that the buckle between the clamping groove 23 and the clamping piece 72 is released, then the external plugboard 21 is pushed upwards, the plug connector 2 can be pushed out of the plug cavity, and then the lead 9 is lifted upwards, so that the lead 9 can be removed. Further, a plurality of ribs 211 may be provided on the outer side of the external board 21 to facilitate pushing of the external board 21.
It will be appreciated that the length of the external plug board 21 is slightly shorter than that of the internal plug 22, the lower end structure of the external plug board 21 may be configured as a butt-joint arc 212, and the bottom structure of the corresponding socket cavity on the side wall of the housing 1, where the cavity is formed, may be configured as a semicircular arc, so that the butt-joint arc 212 can form a circular hole corresponding thereto, thereby facilitating the installation of the sheath 91. Based on the insertion margin of the insert 22, the span of the mating arc 212 of the lower end structure of the external insert plate 21 may be slightly smaller than the diameter of the semicircular arc.
It will be appreciated that the resilient plate 73 is not in contact with the side wall of the socket when the dial block 71 is not pushed backwards.
A limiting plate 61 is arranged below the opposite side of the deflector rod 7, the limiting plate 61 is of a streamline convex structure, and the specific structure can be shown in fig. 7 and 10; when the insert 22 presses down the wire 9 to the limiting plate 61, the limiting plate 61 can push the wire 9 to the cutting edge direction of the clamping knife 3, so that the clamping knife 3 can be in contact conduction with the wire 9.
The lower end structure of the inner insert 22 is an eccentric arc 24, and the eccentric direction is one side far away from the clamping knife 3, so that the inner insert 22 can push the wire 9 to slide to one side far away from the clamping knife 3 when the wire 9 is pressed down; the pushing direction of the eccentric arc 24 to the wire 9 is substantially the same as the sliding direction of the wire 9 along the arc-shaped cutting edge of the clamping knife 3.
The highest point of the protruding structure of the limiting plate 61 is higher than the cutting edge of the clamping knife 3, so when the position of the wire 9 is not lower than the highest point of the protruding structure of the limiting plate 61, the wire 9 can be directly cut by the top edge 31 under the double functions of the eccentric arc 24 and the limiting plate 61. It will be appreciated that as the cutting depth of the top blade 31 increases, the height of the wire 9 moves downward, and the arc blade moves, the wire 9 will slide toward the lower right side of the clamp 3 along the arc blade as soon as the height of the wire 9 is lower than the highest point of the protrusion structure of the limiting plate 61.
Based on structural rationality, the middle part of the lower end of the inner insert 22 is provided with a plate withdrawal groove 222 corresponding to the limiting plate 61 at the high-position end of the eccentric arc 24, so that when the inner insert 22 presses down the lead 9, the basic posture of the inner insert 22 is unchanged and the insertion depth of the inner insert 22 can be limited by the stop of the limiting plate 61.
The middle part of the lower end of the inner insert 22 is provided with a tool retracting groove 221 at the lower end of the eccentric arc 24 corresponding to the movable range of the cutting edge of the clamping tool 3, so that the cutting edge of the clamping tool 3 and the insert 2 do not interfere with each other.
Referring to fig. 10, based on the structural characteristics of the arc-shaped edge and the limiting plate 61, when the wire 9 is located above the highest protruding position of the limiting plate 61, the wire 9 will be pushed to one side of the clamping knife 3 along with the descending of the height of the wire 9, and when the wire 9 is pressed down above the arc-shaped edge, the wire 9 is located approximately near the highest protruding position of the limiting plate 61, so that the top edge 31 of the clamping knife 3 can perform preliminary circular cutting on the wire 9.
When the height of the wire 9 is lower than the highest protruding position of the limiting plate 61, the wire 9 can slide downwards to the right, and is consistent with the trend of the arc-shaped blade, so that edge sliding and variable cutting can be realized, and the wire 9 is subjected to short-distance circular cutting, which can be a deep circular cutting.
When the wire 9 is completely under the limiting plate 61, the cutting groove diameter formed by cutting the front edge along the arc-shaped edge is abutted to the wire core of the wire 9 and is communicated with the wire core.
It can be understood that the relative positions of the limiting plate 61 and the clamping knife 3 can be optimally adjusted according to the thickness of the wires applicable to the wiring terminal, so that when the clamping knife 3 is at the initial position, the spacing between the clamping knife 3 and the limiting plate 61 can be matched with the wires 9 with the optimal size, and circular cutting conduction is completed.
It can be understood that when the cutting groove diameter formed by short-section circular cutting of the wire core by the arc-shaped blade is abutted by the front end blade, the front end blade is clamped in the cutting groove diameter, so that the wire core of the wire 9 is not easy to fall off from the inserting cavity. For the non-stripped wire 9, the envelope may also act as a partial stop.
It will be appreciated that for the wire 9 that is not stripped, the preliminary circular cut is a circular cut of the top edge 31 to the outer envelope of the wire 9; and the depth circular cutting is circular cutting of the wire core. For the wire 9 which has been peeled in short distance, the preliminary circular cutting and the deep circular cutting are all circular cutting of the wire core. Compared with cables which are not peeled or have thicker outer skins, the cable has the advantages of good short-distance peeling connection effect and stable conduction.
For the embodiment of the invention, the preferred treatment before connection to the wire 9 is: the outer skin ring cutting is carried out on the wire 9 coated with the outer skin, the ring cutting position corresponds to the position of the clamping knife 3, the clamping knife 3 can directly ring cut the wire core to form a deeper cutting groove diameter, and meanwhile, the outer skin of the wire 9 can stop the wire 9 from falling off.
Based on the basic structure of the above-mentioned connection terminals, the present invention also proposes a connection terminal block, as shown in fig. 13, which is formed by assembling a plurality of connection terminals in parallel to a substrate 8, and a plurality of rows of connection terminals can be assembled on the substrate 8 at the same time, so that one connection terminal block at least comprises one row of connection terminals.
The above description may be implemented alone or in various combinations and these modifications are within the scope of the present invention.
