Description

Technical Field

[0001] This utility model relates to wiring terminals. Background Technology

[0002] An existing terminal block includes an insulating base and a wiring assembly. The insulating base includes two interlocking shells, each with a first protrusion and a second protrusion formed within it. The second protrusion is located above the center of the first protrusion. After the two shells are engaged, the first protrusions on the two shells interlock to form a mounting boss, and the second protrusions on the two shells interlock to form a limiting boss. Wiring slots are formed on the left and right sides of the limiting boss within the insulating base, and a positioning channel connecting the two wiring slots is formed between the top surfaces of the limiting boss and the mounting boss. The wiring assembly includes a conductive plate supported on the mounting boss. The conductive plate passes through the positioning channel, and its two ends are respectively located in the two wiring slots and fitted with bolt and nut pairs for securing the wires. The mounting boss has anti-rotation recesses for inserting the bolt heads of the bolt and nut pairs. The corresponding anti-rotation recesses are formed by combining half-grooves separately provided on the first protrusion. A protective flip cover is installed on the limiting boss, which can cover and open the top opening of the wiring slot.

[0003] The existing terminal block structure described above has the following drawbacks: 1. The insulating base uses a two-piece shell design. The limiting boss is formed by interlocking second protrusions molded on the two shells. When assembling the wiring assembly, the assembly is inserted into one shell and then snapped onto the other shell, making the assembly of the wiring assembly onto the insulating base inconvenient. 2. The insulating base is formed by the interlocking of two shells, resulting in the bottom track mounting structure of the insulating base typically being an assembled snap-fit ​​component, which is complex and cumbersome to install. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a terminal block with a reasonable structural design and convenient assembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A terminal block includes an insulating base, protective flip covers, and a wiring assembly. The insulating base contains a mounting boss, a limiting boss, two wiring slots, and a positioning channel. The two wiring slots are arranged opposite each other on either side of the limiting boss.

The outer locking seat is U-shaped, and the open end of the outer locking seat is fastened to the bottom wall of the track mounting groove. A locking slot for the insertion of the track is formed between the outer locking seat and the inner elastic plate. When the head of the outer locking seat is pushed, it is displaced by the deformation of the two connecting pieces of the outer locking seat. The head of the outer locking seat is recessed on one side of the locking slot for the sliding groove of the track edge to slide into.

[0011] Preferably, the distal connecting piece of the outer card holder is inclined outward from its head end to its root end.

Detailed Implementation

[0015] See appendix Figures 1-8This utility model discloses a terminal block comprising an insulating base 1, a protective flip cover 2, and a wiring assembly 3. The insulating base 1 contains a mounting boss 11, a limiting boss 12, two wiring slots 13, and a positioning channel 14. The two wiring slots 13 are arranged opposite each other on both sides of the limiting boss 12. The positioning channel 14 is located between the bottom of the limiting boss 12 and the top surface of the mounting boss 11, connecting the two wiring slots 13. Two protective flip covers 2 are mounted on the limiting boss 12 for opening and closing the top openings of the wiring slots 13. The wiring assembly 3 includes a conductive plate 31 positioned and supported on the top surface of the mounting boss 11, the conductive plate 31 penetrating the positioning channel 11. 4. The conductive plate 31 extends into two wiring slots 13 at both ends, and each slot is equipped with a set of bolt and nut pairs for fixing the wires. The conductive plate 31 has bolt through holes. After the bolt 32 of the bolt and nut pair passes through the bolt through hole, the nut 33 is screwed on. The mounting boss 11 has an anti-rotation groove 111 for the head of the bolt 32 to be inserted. The insulating base 1 includes a base body 1-1 and a mounting block 1-2 used as a limiting boss 12. The base body 1-1 is integrally formed with the mounting boss 11 and a through groove 1-11 on the side of the mounting boss 11. The through groove 1-11 has an open opening at the top and both ends in the length direction. An assembly station is provided in the middle of the through groove 1-11, such as... Figure 3 As shown, the wiring assembly 3 is installed on the mounting boss 11 through the open opening of the through slot 1-11. Then, the mounting block 1-2 at the assembly station is inserted to limit and fix the wiring assembly 3. After the mounting block 1-2 is installed at the assembly station, the through slot 1-11 defines two wiring cavities 13 and a positioning channel 14. The insulating base adopts an assembly design of the base body and mounting blocks, which is convenient to process and form, and the overall structure is robust and reliable. In addition, with the insulating base structure design, the wiring assembly is pre-placed on the mounting boss through the open opening of the through slot, and then the mounting block at the assembly station is inserted to limit and fix the wiring assembly, making the overall assembly simple and convenient.

[0016] To further facilitate assembly, the top surface of the mounting boss 11 is formed with a support protrusion 112 at the assembly station. A support protrusion 112 is provided on both sides of the through groove 1-11 in the width direction. The conductive plate 31 is positioned between the two support protrusions 112, and the bottom of the mounting block 1-2 is supported on the support protrusions 112. The support protrusions 112 provide positioning for the conductive plate and support for the mounting block.

[0017] As a simple, safe, and easy-to-assemble design, the installation station of the through groove 1-11 is provided with mounting wall plates 1-12. Both sides of the through groove 1-11 in the width direction are provided with mounting wall plates 1-12 integrally formed with the base body 1-1. The mounting block 1-2 is inserted between the two mounting wall plates 1-12 and fixed to the mounting wall plates 1-12 with snap-fit ​​fasteners. The mounting block is assembled by inserting it into the through groove, making the installation of the mounting block firm, reliable, and convenient, while ensuring a neat and aesthetically pleasing overall appearance. The snap-fit ​​fastening structure can be achieved by having snap holes 1-121 on the two mounting wall plates 1-12 and snap heads 1-21 on the mounting block 1-2, with the snap heads 1-21 engaging with the snap holes 1-121 to achieve snap-fit ​​fastening. Positioning protrusions 1-122 are provided on the inner walls of the two mounting wall plates 1-12, and sliding slots 1-22 are provided on the mounting block 1-2, with the positioning protrusions 1-122 positioning and fitting into the sliding slots 1-22. This makes the installation of the mounting blocks more secure and reliable.

[0018] like Figure 7 , Figure 8 As shown in the figure, in one embodiment of this utility model, the bottom of the base body 1-1 is recessed with a track mounting groove 1-13. A pair of locking feet 15 are provided within the track mounting groove 1-13 to lock the insulating base 1 onto the bearing track (not shown in the figure). The locking feet 15 are integrally formed with the base body 1-1. When the insulating base adopts an integrally formed base body design, the locking feet can be integrally formed directly at the bottom of the base body, simplifying the structure and eliminating the need for separate accessory installation procedures.

[0019] like Figure 7 and Figure 8 As shown, preferably, the locking foot 15 includes an inner elastic plate 151 and an outer plate 152. The roots of both the inner elastic plate 151 and the outer plate 152 are integrally formed with the bottom wall of the track mounting groove 1-13. Both have elastic deformation capability. The free end of the inner elastic plate 151 is provided with a protruding rib 1511 protruding towards the outer plate 152. The outer plate 152 is U-shaped. The open end of the outer plate 152 is fastened to the bottom wall of the track mounting groove 1-13. A locking slot 150 for the insertion of the track is formed between the outer plate 152 and the inner elastic plate 151. When the head of the outer plate 152 is pushed, it is displaced by the deformation of the two connecting pieces 1521 of the outer plate 152. The head of the outer plate 152 is recessed on one side of the locking slot 150 for the sliding groove 1522 for the sliding insertion of the edge of the track. Both the inner elastic plate and the outer bracket are elastic, which enables a more reliable installation of the load-bearing rail. In addition to its elastic deformation capability, the outer bracket also has strength to ensure reliable fixation of the load-bearing rail.

[0020] The distal connecting piece 1521-1 of the outer card holder 152 is inclined outward from its head to its root. This provides an oblique support effect on the outer side of the outer card holder, which can further reduce the deformation capacity of the outer card holder and ensure the reliability of fixing the load-bearing rail.

[0021] Of course, such as Figure 9 As shown, the locking foot 15 can also be set with two elastic plates, but while the elastic plates have strong elastic deformation capabilities, they are not strong enough to fix the load-bearing rail.
