Description

Screw-free quick connection terminal

Technical field

The invention specifically relates to a screw-free quick connection terminal.

Background technique

As we all know, the terminal is a kind of intermediate connector used to realize the electrical connection, and its main function is to facilitate the electrical connection of the wire; there are generally two types of terminal in the existing market, one of which is to use screws to connect the wires. Fastened terminal blocks. Because of the need to adjust the tightening of the screws when connecting the wires, the terminal blocks of this structure greatly affect the installation efficiency of electricians, and their use occasions are more sophisticated, such as in turbulent environments or outdoor occasions. After a long time of use, the screws are easier to loosen, which will cause the wires to fall off or have poor contact, which limits their service life; the second is the fast connection terminal without screw adjustment. This kind of screw-free structure terminal is also everywhere in the market. It can be seen that, however, due to the different structures and materials of conductive parts and reeds used by various manufacturers, the disadvantages are also obvious, mainly reflected in the unreliable contact between the wire and the reed, and the contact between the conductive part and the reed. At the same time, the applicant, based on the turbulence of the connection terminals in the existing market, has developed and designed the new structure of the present invention with a screw-free quick connection connection terminal after R&D and design.

The purpose of the present invention is to provide a screw-free quick connection terminal with novel design, stable and reliable structure, and convenient wiring.

Technical solutions

In order to achieve the above-mentioned object, the present invention relates to a screw-free quick connection terminal, which includes an incoming line insulating shell and an outgoing line insulating shell that are snapped into an integral structure in the axial direction, and an inner cavity of the connecting terminal. A terminal seat, a conductive plate, a V-shaped circlip, and an end cover. A wire inlet hole is opened on the axial end surface of the wire inlet insulating housing, and the inner cavity of the wire inlet insulating housing is connected to the wire inlet hole. A communicating axial adapting groove, the terminal seat is adapted to the axial adapting groove in the axial direction; the terminal seat has an end head and an end tail, and a plug-in interface is formed on the end head, The plug-in port corresponds to the wire inlet hole in the axial direction, so that a conductive medium such as a hard wire is directly inserted into the plug-in port position through the wire hole and forms a reliable contact (ie, electrical connection). A figure eight socket is formed on the end of the end, and one end of the conductive plate is inserted into the figure eight socket so as to achieve direct and reliable electrical connection and contact between the conductive plate and the terminal base; the end cover has an axially extending V-shape Boss, the V-shaped circlip is adapted to the V-shaped boss in the axial direction, and the V-shaped circlip is provided with two stamped and formed claw pieces, and the gap between the claw pieces is formed For the clamping opening for inserting the conductive plate, in the present invention, the clamping opening is preferably in the middle position of the V-shaped circlip (that is, the position of the protruding tip of the V-shaped circlip), and the V-shaped boss and An axial slot is opened at the corresponding position of the conductive plate, and the end cover is provided with an axial outlet hole penetrating the V-shaped boss, and the axial outlet hole is distributed on the upper and lower sides of the axial slot. On both sides, when one end of the conductive plate fits into the axial slot, only the wire needs to be inserted into the axial outlet hole, and then clamped by the claws on the V-shaped circlip, then It can meet the requirements of stable wiring. At the same time, this structure can also meet the requirements of one-in and two-out tap wiring, that is, an incoming line is guided by the current of the terminal base and the conductive plate, and the upper and lower ends of the matching conductive plate are clamped The structure of the wire, obviously, forms a current tapping method in which one wire is introduced from the wire inlet and two wires are drawn from their respective axial outlet holes.

In this specification, the inner cavity of the outgoing insulating housing has an insulating sealing plate that separates the inner cavity. The insulating sealing plate is provided with perforations for penetrating the conductive plate, and the insulating sealing plate effectively protects the connecting terminal of the present invention. The inlet side and the outlet side are insulated from each other, and the conductive plate is arranged axially on both sides of the insulating sealing plate by opening perforations on the insulating sealing plate, which improves the safety of use and the perforation of the insulating sealing plate. It acts as a bearing limit for the conductive plate, so that the conductive plate (ie, the conductive plate) is not easily shifted in the inner cavity of the terminal of the present invention, and the positioning is reliable, thereby improving the compactness and reliability of the overall structure of the terminal.

As a further arrangement of the present invention, it is also used as a further description of the specific structure of the terminal block of the present invention as follows: the end head and the end tail of the terminal block are connected by a coupling plate, and the end head has a connection plate from the coupling plate. The upper and lower side edges of one end are connected pieces extending perpendicular to the connecting plate, and a static spring extending obliquely is formed on the connecting piece far away from one side edge of the wire inlet hole in the axial direction The plug-in interface is located between the upper and lower static reeds; the end tail has upper and lower side edge positions that are far away from the connecting plate and one end of the wire inlet hole, and are perpendicular to the For the horizontal pressing plate extended by the connecting plate, the upper and lower sides of the eight-shaped socket are formed with pressure spring plates that are integrally structured with the horizontal pressing plate. In the present invention, the upper end surface of the horizontal pressing plate is provided with a wedge-shaped protrusion, and a position corresponding to the wedge-shaped protrusion in the longitudinal direction in the axial adapting groove is provided with a wedge-shaped pressing block. After being fitted into the axial fitting groove, the wedge-shaped pressing block longitudinally squeezes the wedge-shaped protrusion, thereby deforming the horizontal pressing plate in the pressing direction, so as to improve the contact between the pressing spring and the conductive plate reliability.

In the present invention, the specific structure of the matching between the incoming line insulating shell and the outgoing line insulating shell is described as follows: on the incoming line insulating shell, the side corresponding to the outgoing line insulating shell forms an axial extension The inner ring wall has at least two radially concave axial grooves on the inner ring wall, and a guide post is formed on the outlet insulating housing at a position corresponding to the axial groove, and the guide The column is adapted to the axial groove, and the incoming line insulating housing is sleeved in the outgoing line insulating housing through the guiding action between the axial groove and the guide post, and forms a circumferential rotation limit. The above structure can only explain the limit in the circumferential direction of rotation between the incoming line insulating housing and the outgoing line insulating housing, but cannot limit the limit in the axial direction. Therefore, as a further improvement, the advance A clip strip is provided on the outer circumferential wall of the wire insulation shell, and a clamping hole is formed on the outlet insulation shell at a position corresponding to the clip strip, and the inlet insulation shell and the outlet insulation shell pass through The clamping strip is connected with the clamping hole to form an axial limit.

As a further description of the specific structure of the terminal of the present invention, the inner cavity of the outgoing insulating housing and the position corresponding to the V-shaped boss form an axial deep groove extending to the insulating sealing plate, and the V-shaped A limit frame edge is formed on the circlip at the positions on both sides of the claw piece, and the position corresponding to the limit frame edge in the axial deep groove forms a lateral step, and the limit frame edge is in the The position of the lateral steps forms abutment. It is not difficult to understand. The edge of the limit frame (that is, the V-shaped circlip) is bidirectionally abutted through the V-shaped boss and the side steps, which achieves the bidirectional compression of the V-shaped circlip. In the axial deep groove, this structure allows the wire (especially the hard wire) to be inserted from the axial outlet hole, and promotes the opening of the claw, thereby avoiding the deflection of the V-shaped circlip during the clamping of the wire. Shift, further reflects the reliability of its wiring.

Beneficial effect

Through the design improvement of the above technical solution, the wiring terminal of the present invention only needs to insert the wire directly into the wire inlet and the axial outlet hole to achieve electrical connection, and does not require any other wiring procedures such as screwing screws, which is achieved in a true sense. The electrical connection of the wire is extremely simplified, and since the main accessories of the inner cavity of the terminal of the present invention are the terminal base, the conductive plate and the V-shaped circlip, the terminal base is directly adapted to the axial direction of the incoming line insulating shell in the axial direction In the fitting groove, and fastened in the axial fitting groove through the mutual pressing action between the wedge-shaped pressing block in the axial fitting groove and the wedge-shaped protrusion on the terminal base, and at the same time, it is inserted in the The conductive plate in the figure eight socket is also firmly clamped due to the longitudinal extrusion of the wedge-shaped pressing block on the wedge-shaped protrusion, and then the conductive plate is inserted into the insulating sealing plate structure, that is, the insulating sealing plate is also opposite to the conductive plate. Play the role of limit and load, so that the assembly structure of the conductive plate in the inner cavity of the terminal essentially forms at least two base points for fastening, and then the V-shaped circlip inserted on the conductive plate is subjected to the V-shaped The two-way abutting action of the boss and the lateral step makes the assembly structure of the parts of the terminal of the present invention compact, reliable, convenient and stable in connection.

The axial adapting groove 11 is adapted; further combining with 5, it is obvious that the terminal block 3 has an end head 30 and an end tail 31, the end head 30 is formed with a plug interface 300, and the plug interface 300 is on the shaft The direction corresponds to the wire inlet 10 so that conductive media such as a hard wire can be directly inserted into the plug-in interface 300 through the wire inlet 10 and form a reliable contact (ie electrical connection). A figure eight socket 310 is formed on 31. As shown in FIG. 8, one end of the conductive plate 4 is inserted into the figure eight socket 310 to achieve direct and reliable electrical connection and contact between the conductive plate 4 and the terminal base 3; Figure 2 combines It can be seen from FIG. 7 that the end cover 6 has an axially extending V-shaped boss 60. In this embodiment, the V-shaped circlip 5 and the V-shaped boss 60 fit in the axial direction, (ie The recessed angle of the V-shaped circlip 5 is adapted to the convex angle of the V-shaped boss 60), and in conjunction with FIG. 6, it can be seen that the V-shaped circlip 5 has two claw pieces 50 formed by stamping. A clamping opening 51 for inserting the conductive plate 4 is formed between the claw pieces 50. As clearly shown in FIG. 6, the clamping opening 51 is formed in the middle position of the V-shaped circlip 5 (that is, the V-shaped circlip 5). 2 and 7 shows that the V-shaped boss 60 is provided with an axial slot 600 at a position corresponding to the conductive plate 4, and the end cover 6 is provided with a through hole The axial outlet holes 61 of the V-shaped boss 60 are distributed on the upper and lower sides of the axial slot 600, when one end of the conductive plate 4 fits into the axial slot 600 When the wire is inserted into the axial outlet hole 61, and then clamped by the claw piece 50 on the V-shaped circlip 5, the stable wiring requirement can be met. Obviously, in this embodiment, the claw The angle between the sheet 50 and the conductive plate 4 is less than 90°. At the same time, this structure can also meet the requirements of one-in-two-out tap connection, that is, after an incoming line is guided by the terminal base 3 and the conductive plate 4, it is matched The structure in which the upper and lower ends of the conductive plate 4 both clamp the wires can be obvious, forming a current tapping method in which one wire is introduced from the wire inlet and two wires are drawn from their respective axial outlet holes 61. That is to say, the upper and lower ends of the conductive plate 4 can be respectively connected with a wire and lead out.

In this embodiment, in order to improve the insulation between the inlet end and the outlet end, and as shown in FIG. 4, the inner cavity of the outlet insulating housing 2 has an insulating sealing plate 20 separating the inner cavity, and the insulating sealing plate 20 The upper part is provided with a through hole 200 for penetrating the conductive plate 4, and the insulating sealing plate 20 effectively separates the incoming and outgoing wires of the terminal of this embodiment in an insulating manner, and the insulating sealing plate 20 is provided with a through hole. The conductive plate 4 is axially inserted on both sides of the insulating sealing plate 20 by the method of 200, which improves the safety of use. At the same time, the perforation 200 of the insulating sealing plate 20 also plays a bearing and limiting role on the conductive plate 4, making it ( That is, the conductive plate 4) does not deviate in the inner cavity of the wiring terminal in this embodiment, and the positioning is reliable, thereby improving the compactness and reliability of the overall structure of the wiring terminal.

In this embodiment, Fig. 2 combined with Fig. 5 shows that, as a description of the specific structure of the terminal block 3 of this embodiment, the following is a description: the end 30 and the end 31 of the terminal block 3 are connected by a connecting plate 32, The end head 30 has a connecting piece 301 extending perpendicular to the connecting plate 32 from the upper and lower side edges of one end of the connecting plate 32. The connecting piece 301 is far away from the connecting piece 301 in the axial direction. A side edge of the wire inlet 10 forms a static reed 302 extending obliquely, and the insertion port 300 is located between the upper and lower static reeds 302; , The horizontal pressure plate 311 extending from the upper and lower sides of one end of the wire inlet hole 10 is perpendicular to the connecting plate 32, and the upper and lower sides of the eight-shaped socket 310 are formed with the horizontal pressure plate 311 is a compression spring piece 312 with an integral structure.

There is a wedge-shaped pressing block 110 at the position where the terminal block 3 axially fits into the axial fitting groove 11, the wedge-shaped pressing block 110 longitudinally presses the wedge-shaped protrusion 3110, thereby causing the horizontal pressing plate 311 Deform in the extrusion direction to improve the contact reliability between the pressure spring 312 and the conductive plate 4. Obviously, the "upper end surface" of the horizontal pressure plate 311 in this embodiment is only a description of the relative positional relationship, which is different from the coupling plate 32. For the horizontal pressing plate 311 extending from one side edge, the wedge-shaped protrusion 3110 is provided on the lower end surface of the horizontal pressing plate 311 (that is, the position of the upper end surface of the horizontal pressing plate 311 mentioned above), which realizes that the horizontal pressing plate 311 is on the axis. For those skilled in the art, the two-way squeezing effect that is squeezed toward the middle can be applied to the fitting groove 11 without affecting the understanding.

In this embodiment, the specific structure for matching between the incoming line insulating housing 1 and the outgoing line insulating housing 2 is described as follows: Fig. 2 is shown in conjunction with Fig. 3, the incoming line insulating housing 1 is insulated from the outgoing line The corresponding side of the housing 2 forms an axially extending inner ring wall 12, and the inner ring wall 12 has two radially inwardly concave axial grooves 120. As shown in FIG. 4, the outlet insulating shell A guide post 21 is formed on the body 2 at a position corresponding to the axial groove 120, and the guide post 21 is adapted to the axial groove 120. The inlet insulating housing 1 passes through the axial groove. The guiding action between the slot 120 and the guide post 21 is sleeved in the outlet insulating housing 2 and forms a circumferential rotation limit; obviously, the above structure can only illustrate the inlet insulating housing 1 and the outlet insulating housing The limit in the circumferential direction of rotation between 2 and the limit in the axial direction cannot be limited. Therefore, as a further preferred embodiment of this embodiment, the outer circumferential wall of the inlet insulating housing 1 has an axial extension The top of the clip 13 is formed with a wedge-shaped clip portion 130, and a clip hole 23 is formed on the outlet insulating housing 2 at a position corresponding to the clip 13, and the clip hole 23 is A clamping wall 230 is formed, and the incoming line insulating housing 1 and the outgoing line insulating housing 2 are clamped by the wedge-shaped clamping portion 130 of the clamping strip 13 and the clamping wall 230 on the clamping hole 23 Connect to form an axial limit.

In this embodiment, as a further description of the specific structure of the connection terminal, as shown in FIG. 4, the inner cavity of the outlet insulating housing 2 and the position corresponding to the V-shaped boss 60 are formed to extend to the insulating seal. The axial deep groove 24 of the plate 20 is clearly shown in FIG. 4, the outlet insulating housing 2 has two axial deep grooves 24, and an insulating partition 240 is formed between the two axial deep grooves 24, as shown in FIG. 2 It can be seen from the display shown in FIG. 6 that a limit frame edge 52 is formed on the V-shaped circlip 5 on both sides of the claw piece 50, and the axial deep groove 24 corresponds to the limit frame edge 52 A side step 241 is formed at the position of the limit frame edge 52, and the limit frame edge 52 forms abutment at the position of the side step 241. It is not difficult to understand that the limit frame edge 52 is bidirectionally connected through the V-shaped boss 60 and the lateral step 241 Abutting, that is, the V-shaped circlip 5 is compressed in the axial deep groove 24 in both directions. Such a structure allows the wire (especially a hard wire) to be inserted from the axial outlet hole 61 and encourages the claw piece 50 During the process of opening and clamping the wire, the deviation of the V-shaped circlip 5 is avoided, and the reliability of the wiring is further reflected.

Example 2:

It can be seen from the drawings of the specification that Figures 9 and 10 show schematic diagrams of Embodiment 2 of the present invention. The main difference between Embodiment 2 and Embodiment 1 is: Embodiment 1 is equipped with two terminal blocks 3 and two There are two conductive plates 4 and two semicircular end covers 6, that is, two wire inlet holes 10 and four axial wire outlet holes 61; and in the structure of embodiment 2, the inner cavity of the terminal is provided with three terminal seats 3 And three conductive plates 4 and three fan-shaped end caps 6 with an arc of 120° (obviously, the end cap 6 can be applied to the spirit of the technical solution of this embodiment only if it meets the condition of being assembled into a full circle ), that is, there are three wire inlet holes-9-10 and six axial wire outlet holes 61; it can be seen that the structural principle between embodiment 2 and embodiment 1 is the same, and one wire corresponds to one terminal block 3. It is electrically connected to a conductive plate 4, a V-shaped circlip 5, and two axial outlet holes 61 on a V-shaped boss 6. That is, embodiment 1 shows a two-way electrical connection, while embodiment 2 Three-way electrical connection shown.

Regardless of the embodiment 1 or the embodiment 2, the wiring terminals involved only need to insert the wires directly into the wire inlet 10 and the axial wire outlet 61 to achieve electrical connection, and no other wiring procedures such as screwing screws are required. In the true sense, the ultimate simplification of the electrical connection of the wires is achieved, and since the main accessories of the inner cavity of the wiring terminal in the above embodiment are the terminal block 3, the conductive plate 4 and the V-shaped circlip 5, the terminal block 3 is in the axial direction. It is directly fitted into the axial fitting groove 11 of the inlet insulating housing 1, and is squeezed between the wedge-shaped pressing block 110 in the axial fitting groove 11 and the wedge-shaped protrusion 3110 on the terminal base 3 And fastened in the axial adapting groove 11, at the same time, the conductive plate 4 inserted in the figure eight socket 310 is also firmly clamped due to the longitudinal compression of the wedge-shaped protrusion 3110 by the wedge-shaped pressing block 110 The conductive plate 4 is then inserted into the insulating sealing plate 20. That is, the insulating sealing plate 20 also plays a role of limiting and carrying the conductive plate 4, so that the assembly structure of the conductive plate 4 in the inner cavity of the terminal is essential. At least two base points (that is, the two base points of the figure eight socket 310 position and the perforation 200 position) are formed on the upper part, and then the V-shaped circlip 5 inserted on the conductive plate 4 is subjected to the V-shaped boss 60 and The two-way abutment effect of the lateral step 241 makes the assembly structure of the components of the terminal in the above embodiment achieve the effects of compactness, reliability, convenient and stable wiring.
