Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

In order to solve the above problems, the present invention provides a terminal block, please refer to fig. 1-12 and 14, wherein the leveling structure mainly comprises a housing 1, a plug connector 2, a knife clamp 3, a mounting cavity 4 and a connecting spring 5, the housing 1 comprises a first block 11 and a second block 12, the mounting cavity 4 is arranged in each of 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 installation cavity 4, the front end of the clamping knife 3 is arranged in an inserting cavity arranged in front of the installation cavity 4, and the inserting cavity is communicated with the outside, so that a wire 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 from the upper end opening of the insertion cavity and presses the wire 9 downwards, so that the wire 9 is connected and conducted with the front end cutting edge of the clamping knife 3; the bayonet 3 is in sliding communication with the connecting elastic sheet 5, so that the connecting elastic sheet 5 can be in connection with and communicated with 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 arranged in a central symmetry, and the structure in the first block 11 and the structure in the second block 12 are also in a central symmetry, as shown in fig. 2 and 9.

The housing 1 further includes a bottom plate 13, and the bottom plate 13 is used for carrying the structures and devices in the two blocks. The bottom plate 13 can be provided with arc-shaped depressions at positions corresponding to the insertion cavities so as to adapt to the wires 9 with different thicknesses. Understandably, the wires 9 with different thicknesses not only indicate the diameter of the wire core, but also indicate the thickness of the outer sheath of the wire core, and whether the wire is suitable for the accurate circular cutting conduction of the cutter 3 and the wire core, and further, the distance between the cutter 3 and the wire core should meet the requirement that the cutter 3 and the wire core realize the circular cutting conduction.

Taking the first block 11 as an example for explanation, the inside of the housing 1 is provided with the installation cavity 4, the rear end structure of the clamping knife 3 is arranged in the installation cavity 4, the front end of the clamping knife 3 is arranged in the plugging cavity, the front end of the clamping knife 3 is provided with a cutting edge, and the short-section circular cutting can be performed on the wire 9, 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 blade 31 and a knife head 32, the top blade 31 is located above the knife head 32, the top blade 31 is used for performing short-section circular cutting on the wire 9, and the knife head 32 is used for clamping and conducting the wire 9.

Specifically, the top blade 31 includes a horizontal blade and an arc blade, which are hereinafter referred to as a horizontal blade and an arc blade. The horizontal blade is located behind the arc-shaped blade, and the horizontal blade and the arc-shaped blade are both located above the tool bit 32. The front end of the tool bit 32 is also provided with a cutting edge, the cutting edge at the front end is positioned at the foremost end of the whole clamping tool 3, which is referred to 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 connected in a smooth transition mode, so that the blade edge of the clamping knife 3 can form an approximately integrated cutting edge, and the wire 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 area of the knife head 32 and is arranged on two sides of the clamping knife 3; the tail cone 34 is arranged in the middle of the tail section of the bayonet 3. Corresponding to the rear section of the clamping knife 3, the installation cavity 4 comprises a slideway cavity and a telescopic cavity, the telescopic cavity is positioned at the front end of the slideway cavity and communicated with the splicing cavity, a spring 41 is arranged in the telescopic cavity, a fixed column is arranged on the bottom wall of the telescopic cavity and used for fixing one end of the spring 41, and the other end of the spring 41 is butted and fixed to the tail cone 34; the two side walls of the slideway cavity are symmetrically provided with slideways 42, the sliding blocks 33 can slide in the slideways 42, and the length of the slideways 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 bayonet 3 on the lead 9 is stable. Further, when the arc-shaped blade of the clamping knife 3 performs circular cutting on the wire 9, the requirement for external force for pushing the clamping knife 3 to slide backwards is large, the external force for pressing the wire 9 down is decomposed again, the sliding condition of the clamping knife 3 is not easy to reach, and the arc-shaped blade can perform stable circular cutting on the wire 9 in the circular cutting process.

When the wire 9 height descends to the end of the arc-shaped blade, the wire 9 continuously descends to push the bayonet 3 to slide backwards, so that the abutting pressure between the front end blade and the wire core of the wire 9 is increased, and the circular cutting conduction is stabilized.

It can be understood that a plurality of sets of the sliding blocks 33 and the sliding ways 42 can be provided in cooperation to stabilize the sliding effect, so that the knife 3 can stably realize telescopic sliding. The inner diameter 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 bayonet 3, so that the elastic force of the spring 41 can be completely converted to the bayonet 3.

It can be understood that the top blade 31 and the cutter head 32 can be made of different materials, and based on the requirement of the cutting function of the top blade 31, the cutting blade can be made of a material with higher hardness, such as steel; based on the butt joint and conduction function requirements of the tool bit 32, a material with better conductivity can be adopted for coating to form a conduction blade, such as copper, and an electroplating mode can be adopted for coating. Furthermore, the coating area of the tool bit 32 is limited, and the tool bit is always in sliding connection with the sliding end of the connecting elastic piece 5. If the sliding connection end is in sliding connection with the edge part of the cutter head 32, the elasticity is changed frequently, and the sliding connection is easy to be unstable, so that the sliding connection position is preferably at the middle and rear sections of the cutter head 32, the elasticity change of the sliding connection end is basically consistent, and the sliding connection is stable.

It will be appreciated that the horizontal edge is a transition edge and hardly participates in the circular cutting of the wire 9. The arc-shaped edge is the main edge region of the wire 9 in the girdling stage. The front end blade hardly participates in the circular cutting of the lead 9, only the cutting groove diameter formed by the lead 9 which is subjected to circular cutting is clamped, and the cutting groove diameter is conducted with the core of the lead 9.

In the embodiment of the invention, an elastic sliding sheet connected with the elastic sheet 5 is fixed at one side of the clamping knife 3 away from the shell 1 and at the front end of the mounting cavity 4, and the sliding end of the elastic sliding sheet is in sliding communication with the knife head 32, so that it can be understood that when the clamping knife 3 slides in a telescopic manner, the sliding end of the elastic sliding sheet is always positioned in the area of the knife head 32, namely the sliding end is always in sliding connection and communication with the copper-plated area. Further, a stop block 62 is arranged at the front end of the mounting cavity 4 and at one side of the clamping knife 3 close to the shell 1, and is used for correcting/stopping the basic posture and position of the clamping knife 3. A gap is arranged between the abutting block 62 and the shell 1, and the installation of the sheath 91 can be accommodated.

In the embodiment of the invention, the connecting elastic sheet 5 is connected and conducted with the tool bit 32 of the bayonet 3 in a sliding manner. The connecting spring 5 can directly conduct the leads 9 of the first block 11 and the second block 12; the connecting elastic piece 5 may also be provided with a control switch for controlling the on/off of the conducting wire 9 between the first block 11 and the second block 12, which is as follows:

referring to fig. 2 and 9, the connection terminal is a through type connection terminal, and at this time, two ends of the connection elastic piece 5 are both elastic sliding pieces, which are respectively in sliding conduction with the blades 3 of the first block 11 and the second block 12; the middle part is directly communicated.

Referring to fig. 11 and 12, the connection elastic piece 5 includes a first elastic piece 51, a second elastic piece 52, and a switch device 53, and the elastic sliding pieces of the first elastic piece 51 and the second elastic piece 52 are respectively in sliding connection with the blades 3 in the first block 11 and the second block 12; a control cavity 15 is arranged between the first block 11 and the second block 12, a switch device 53 is arranged in the control cavity 15, and the extending ends of the first elastic sheet 51 and the second elastic sheet 52 are arranged at two ends in the control cavity 15 and connected with the switch device 53, so that the switch device 53 can control the connection/disconnection of the connecting elastic sheet 5.

It will be appreciated that part of the mechanical structure of the switch device 53 floats on the outside of the housing 1 for easy observation and operation. Part of the mechanical structure can be a switch toggle piece, a button, an indicator light and the like. Further, the switch device 53 may be a push-button switch, a toggle switch, an air switch, or the like.

In the embodiment of the present invention, the insertion cavity is formed in the side wall structure of the housing 1, and the specific formation range of the insertion cavity can refer to fig. 7 and 9; the wires 9 are inserted into the plug cavity from the side walls, and the pressing down of the wires 9 is performed by the plug 2.

The plug connector 2 comprises an outer plug board 21 and an inner plug 22, wherein the outer plug board 21 is used for plugging a plugging cavity on the side wall of the shell 1, and the inner plug 22 is used for plugging an inner cavity and an upper port of the plugging cavity of the shell 1.

A lining plate gap 25 is arranged between the lower end of the outer inserting plate 21 and the lower end of the inner inserting piece 22, and the lining plate gap 25 is used for clamping and mounting 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; a baffle 6 is arranged at the opposite side of the bayonet 3 and used for stopping the lead 9; when the plug connector 2 presses the lead 9 downwards, the lead 9 is always positioned in the plug cavity.

Specifically, the sheath 91 comprises an inner lining board 911, an outer lining board 912 and a sleeve 913, wherein the outer lining board 912 and the inner lining board 911 are fixedly connected to the outer wall of the outer end of the sleeve 913, the outer lining board 912 is positioned on the outer side of the inner lining board 911, and the distance between the inner lining board 911 and the outer lining board 912 is not less than the thickness of the outer inserting plate 21; the wire 9 can be threaded within the sleeve 913. The position of the inner lining board 911 facing the bottom board 13 is provided with a flat cut notch, which is convenient for installing the sheath 91. The thickness of the exterior insert plate 21 substantially corresponds to the thickness of the housing 1, facilitating the installation of the sheathing 91.

Specifically, the shift lever 7 further comprises a shift block 71, a clamping piece 72 and an elastic plate 73, a shift groove 14 is formed in the upper surface of the shell 1, the shift block 71 is horizontally arranged in the shift groove 14, the shift block 71 is connected with the upper end of the elastic plate 73, and the lower section of the elastic plate 73 is obliquely and fixedly connected to the lower portion of the side wall of the plugging cavity.

Offer the draw-in groove 23 of extension formula on the lateral wall of interior plug-in components 22, the middle part outside of elastic plate 73 upper segment is provided with fastener 72, make plug connector 2 insert the grafting intracavity downwards and fastener 72 and draw-in groove 23 when accomplishing the buckle, interior plug-in components 22 under the buckle state can continue to push down wire 9 downwards, make wire 9 that the thickness differs all can be pushed down to the below of limiting plate 61, thereby prolong the draw-in groove 23 of certain degree and the joint effect of fastener 72, increase the grafting surplus of interior plug-in components 22, enlarge the scope of pushing down.

When the clamping of the clamping piece 72 and the clamping groove 23 needs to be removed, the poking block 71 is pushed backwards, so that the clamping of the clamping groove 23 and the clamping piece 72 is removed, then the outer inserting plate 21 is pushed upwards, the inserting piece 2 can be pushed out of the inserting cavity, then the wire 9 is pulled upwards, and the removal of the wire 9 can be completed. Further, a plurality of ribs 211 may be provided on the outer side of the exterior insert plate 21 to facilitate pushing of the exterior insert plate 21.

It can be understood that, the length of the external board 21 is slightly shorter than that of the internal board 22, the lower end structure of the external board 21 can be set as a butt arc 212, and the bottom structure of the corresponding plugging cavity on the side wall of the housing 1, which is provided with the cavity, can be set as a semicircular arc, so that the butt arc 212 can form a circular hole corresponding to the butt arc to facilitate the installation of the sheath 91. The span of the butt arc 212 of the lower end structure of the external insertion plate 21 may be slightly smaller than the diameter of the semicircular arc based on the insertion allowance of the internal plug 22.

It will be appreciated that the resilient plate 73 does not contact the side wall of the plug cavity when the dial block 71 is not pushed rearward.

A limiting plate 61 is arranged below the opposite side of the shift lever 7, and the limiting plate 61 is of a streamline convex structure, and the specific structure can be shown in fig. 7 and 10; when the interposer 22 presses the wire 9 down to the position-limiting plate 61, the position-limiting plate 61 can push the wire 9 toward the cutting edge of the blade 3, so that the blade 3 can be in contact with the wire 9.

The lower end structure of the inner plug 22 is an eccentric arc 24, and the eccentric direction is the side far away from the bayonet 3, so that when the inner plug 22 presses the wire 9, the wire 9 can be pushed to slide to the side far away from the bayonet 3; the direction of pushing of the wire 9 by the eccentric arc 24 is substantially the same as the sliding direction of the wire 9 along the arc-shaped edge of the bayonet 3.

The highest point of the convex structure of the limiting plate 61 is higher than the blade of the bayonet 3, so that when the position of the wire 9 is not lower than the highest point of the convex structure of the limiting plate 61, the wire 9 can be directly cut by the top blade 31 under the dual actions of the eccentric arc 24 and the limiting plate 61. It can be understood that, as the cutting depth of the top blade 31 is increased, the height position of the wire 9 is moved downwards, and the curved blade moves in the direction, once the height of the wire 9 is lower than the highest point of the convex structure of the limiting plate 61, the wire 9 will slide along the moving direction of the curved blade to the lower right side of the bayonet 3.

Based on the structural rationality, the lower middle part of the interposer 22 is provided with a plate-withdrawing groove 222 corresponding to the limiting plate 61 at the high-position end of the eccentric arc 24, so that when the interposer 22 presses the wire 9, the basic posture of the interposer 22 is not changed and the inserting depth of the interposer 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 withdrawal groove 221 corresponding to the moving range of the cutting edge of the bayonet 3 at the low end of the eccentric arc 24, so that the cutting edge of the bayonet 3 and the plug-in connector 2 do not interfere with each other.

Referring to fig. 10, based on the above-mentioned structural characteristics of the arc-shaped blade 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 blade 3 as the height of the wire 9 is lowered, and when the wire 9 is pressed down above the arc-shaped blade, the wire 9 is approximately located near the highest protruding position of the limiting plate 61, so that the top blade 31 of the blade 3 can perform a preliminary circular cutting on the wire 9.

After the height of the wire 9 is lower than the highest protruding position of the limiting plate 61, the wire 9 can slide to the lower right, the direction of the wire is consistent with the moving direction of the arc-shaped blade, edge sliding and variable cutting can be achieved, short-distance circular cutting is conducted on the wire 9, and the process can be deep circular cutting.

When the wire 9 is completely under the position-limiting plate 61, the front blade abuts against the core of the wire 9 along the cutting groove formed by cutting the arc blade and is conducted with the core.

It can be understood that the relative position of the limiting plate 61 and the bayonet 3 can be optimally adjusted according to the thickness of the wire suitable for the wiring terminal, so that when the bayonet 3 is at the initial position, the distance between the bayonet 3 and the limiting plate 61 can be matched with the wire 9 with the optimal size, and the 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 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 splicing cavity. For an unpeeled wire 9, the outer sheath may also serve as a partial stop.

It will be appreciated that for an un-stripped wire 9, the preliminary girdling is a girdling of the top edge 31 against the outer sheath of the wire 9; and deep circular cutting is performed on the wire core. For the wire 9 which is subjected to short-distance peeling, the preliminary ring cutting and the deep ring cutting are both ring cutting of the wire core. Compared with a cable without stripping or with a thick outer skin, the short-distance stripping cable has the advantages of good connecting effect and stable conduction.

In the embodiment of the present invention, the preferred processing method before the connection with the lead 9 is: the outer skin girdling is carried out to wire 9 that the cladding has the outer skin, and the position correspondence of girdling position and card sword 3 can for card sword 3 can directly carry out the girdling to the sinle silk and form darker cutting groove footpath, and the outer skin of wire 9 can backstop wire 9 and drop simultaneously.

Based on the basic structure of the wiring terminal, the invention also provides a wiring terminal block, as shown in fig. 13, a plurality of wiring terminals are assembled on the substrate 8 in parallel to form the wiring terminal block, and a plurality of rows of wiring terminals can be assembled on the substrate 8 at the same time, so that one wiring terminal block at least comprises one row of wiring terminals.
