Description

Technical Field

[0002] A wiring terminal is a fitting product used to achieve electrical connection, mainly for providing current transmission between different energized devices. The existing wiring mechanism is usually a direct plug-in wiring terminal, which clamps a wire through the cooperation of a current-carrying conductor and an elastic chuck inside a terminal housing. For example, the utility model patent with the publication number CN207800927U discloses a quick-insert wiring mechanism. Fixed columns for fixing elastic chucks and cavities for accommodating the fixed elastic chucks are respectively provided on the left and right sides inside an insulating housing. The current-carrying conductor is arranged between the cavities, and its left and right ends horizontally extend into the adjacent cavities. Wiring channels for accommodating the insertion of wire joints are provided at positions directly below the jacks at the left and right ends of the current-carrying conductor. The elastic chuck is a U-shaped metal elastic piece. The two ends at the opening of the elastic chuck are a fixed end and a wire-clamping end. A fixed bayonet is provided at the end of the fixed end. A clamping groove capable of clamping the fixed bayonet is provided on one side of the wiring channel. An elastic clamping plate extending into the wiring channel is provided at the end of the wire-clamping end. A wire-clamping panel is provided in the wiring channel, and the wire-clamping panel and the elastic clamping plate form a clamping of the wire joint.

[0003] During the assembly of the wiring mechanism, the elastic chuck needs to be pre-assembled on the wiring channel of the current-carrying conductor, and then the current-carrying conductor and the elastic chuck are together installed into the insulating housing. In this process, the elastic chuck may be displaced, resulting in interference during the installation of the elastic chuck into the cavity. It is also necessary to operate the elastic chuck to ensure that the current-carrying conductor is smoothly installed into the insulating housing. The installation operation is rather cumbersome, reducing the assembly efficiency. Summary of the Utility Model

[0027] The present utility model will be further described below with reference to the embodiments in conjunction with the accompanying drawings.

[0028] Refer to Figures 1 to 6 , a wiring mechanism for quick assembly, including an insulating housing 1, a spring piece unit, and a busbar 3. A wiring position is provided on the left side of the insulating housing 1, and two wiring positions arranged at intervals and in an array are provided on the right side of the insulating housing 1. An assembly cavity 11 is formed on the side wall of the insulating housing 1. Wiring holes 12 and operation holes 13 which are arranged at intervals and communicate with the assembly cavity 11 are provided in a penetrating manner on the wiring position. The wiring holes 12 and the operation holes 13 are both communicated with the assembly cavity 11. The wiring holes 12 and the operation holes 13 on the wiring position are arranged obliquely in the same direction, and both the wiring holes 12 and the operation holes 13 are inclined outward.

[0029] A support column 14 is provided at the position of the assembly cavity 11 relative to the operation hole 13. The outer wall of the support column 14 includes a support surface 141 and two adjacent and opposite limiting surfaces 142. The support surface 141 is a curved surface. An insertion space 5 is formed between the support surface 141 of the support column 14 and the inner wall of the corresponding assembly cavity 11. Oppositely arranged first limiting wall 15 and second limiting wall 16 are formed at the position of the inner wall of the assembly cavity 11 corresponding to the support column 14. The first limiting wall 15 and the second limiting wall 16 are arranged obliquely in the same direction, and both the first limiting wall 15 and the second limiting wall 16 are inclined inward, so that the inclination directions of the wiring holes 12 and the operation holes 13 are staggered with the inclination directions of the first limiting wall 15 and the second limiting wall 16.

[0030] The wiring hole 12 penetrates to the first limiting wall 15, and positioning parts 151 extending downward are provided on both side parts of the first limiting wall 15. The inner wall of the wiring hole 12 penetrates to the inner walls of the two positioning parts 151. A wire port wall 17 extending downward is provided on the side wall of the insulating housing 1 close to the opening of the assembly cavity 11. The wire port wall 17 is integrally formed with the corresponding positioning part 151.

[0031] Card slot 111 is provided on both sides of the assembly cavity 11. A limiting portion 121 is provided on the inner wall of the wiring hole 12, and the bottom surface of the limiting portion 121 is matched with the inner wall of the card slot 111. Preferably, the bottom surfaces of the two limiting portions 121 respectively located on the left and right sides of the insulating housing 1 are matched with the inner walls of the corresponding assembly cavities 11 to form the card slot 111.

[0032] The shrapnel unit includes three shrapnel clips 2, and each shrapnel clip 2 corresponds to each wiring position respectively. The shrapnel clip 2 includes a first elastic section 21, a bending portion 22 and a second elastic section 23 connected in sequence. The end of the first elastic section 21 includes a bent clamping line segment 211, and the end of the second elastic section 23 includes a bent positioning section 231.

[0033] The bus bar 3 is provided with a C-shaped channel 31 for accommodating the shrapnel clip 2 on the side facing the assembly cavity 11. The C-shaped channel 31 includes a clamping plate 311, an outer baffle 312 and a positioning plate 313 integrally formed with each other. The outer baffle 312 and the positioning plate 313 both extend downward to a position corresponding to the bottom of the clamping plate 311. The clamping plate 311 and the positioning plate 313 cooperate with the bus bar 3 to form the opening side of the C-shaped channel 31. Card position ends 32 are provided on both sides of the bus bar 3, and a groove 321 is provided in the middle of the end face of the card position end 32.

[0034] When assembling this wiring mechanism, each shrapnel clip 2 is respectively inserted into the assembly cavity 11. The bending portion 22 is inserted into the through space 5 to pre-assemble the shrapnel clip 2 in the assembly cavity 11. The first elastic section 21 and the second elastic section 23 are respectively pressed against the first limiting wall 15 and the second limiting wall 16 under the action of the bending portion 22 and an assembly space is reserved. The assembly space includes a first assembly gap 8 and a second assembly gap 9. A first assembly gap 8 for the clamping plate 311 to pass through is formed between the clamping line segment 211 and the inner wall of the corresponding assembly cavity 11. A second assembly gap 9 for the positioning plate 313 to pass through is formed between the positioning section 231 and the inner wall of the corresponding assembly cavity 11. The space between the second limiting wall 16 and the limiting surface 142 of the corresponding support column 14 is used to limit the second elastic section 23. The side of the clamping line segment 211 facing the assembly cavity 11 is in contact and cooperation with the corresponding positioning portion 151, which plays a role in limiting the clamping line segment 211.

[0035] The first limiting wall 15 and the second limiting wall 16 are used to limit the shrapnel clip 2 to prevent it from shifting in position, and ensure that the assembly space reserved by the first elastic section 21 and the second elastic section 23 is sufficient for the opening side of the C-shaped channel 31 to pass through, so that the bus bar 3 can be inserted into the assembly cavity 11 without operating the shrapnel clip 2 to complete the rapid assembly operation of this wiring mechanism. The installation operation is relatively simple, reducing the overall assembly difficulty of this wiring mechanism and improving the assembly efficiency.

[0036] In this process, the bus bar 3 is inserted into the assembly cavity 11 through the insertion and alignment of the clamping end 32 and the clamping groove 111. The setting of the groove 321 reduces the contact area between the end face of the clamping end 32 and the inner wall of the clamping groove 111, enabling the bus bar 3 to be inserted into the assembly cavity 11 more smoothly. Moreover, the cooperation between the clamping end 32 and the clamping groove 111 provides good fixation for the bus bar 3, effectively preventing the bus bar 3 from moving left and right. The bottom surface of the limiting portion 121, the bottom surface of the wire port wall 17, and the bottom surface of the positioning portion 151 are all in contact and cooperation with the bus bar 3, and are used to cooperate with the assembly cavity 11 to position the bus bar 3.

[0037] After the wiring mechanism is assembled, a wiring channel 6 for restricting the first elastic section 21 and the second elastic section 23 is formed by the cooperation of the opening side of the C-shaped channel 31 and the inner wall of the assembly cavity 11. The positioning section 231 abuts against the inner wall of the positioning plate 313. There is a contact or clearance fit between the clamping section 211 and the clamping plate 311. The space between the first limiting wall 15 and the limiting surface 142 of its corresponding support column 14 allows the first elastic section 21 to swing. The operation hole 13 corresponds to the first elastic section 21, so that the user can use tools such as a screwdriver or a button post to pass through the operation hole 13 to press down the first elastic section 21 to make it swing around the support column 14, and thus form a wire clamping space 7 between the inner wall of the clamping plate 311 and the clamping section 211 for clamping the wire 4.

[0038] The wire 4 includes a linear metal conductor 42 and an insulating layer 41 covering the metal conduction. Before connecting the wire 4, a small section of the insulating layer 41 at the end of the wire 4 needs to be removed to expose the metal conductor 42 for connection. The inner wall of the clamping plate 311 is inclined towards the first limiting wall 15, and the inclination direction of the inner wall of the clamping plate 311 is the insertion direction of the wire 4. When the wire 4 is inserted into the wiring hole 12, the insulating layer 41 of the wire 4 abuts against the limiting portion 121 in the wiring hole 12, guiding the metal conductor 42 of the wire 4 to smoothly enter the wire clamping space 7 along the wiring channel 6. Moreover, the limiting portion 121 plays a role in structurally supporting the exposed metal conductor 42 of the wire 4. The user can release the first elastic section 21 to make it cooperate with the inner wall of the clamping plate 311 to clamp the exposed metal conductor 42 of the wire 4, thus completing the wiring of the wire 4 and this wiring mechanism.

[0039] Certainly, the above are only typical examples of the present utility model. In addition, the present utility model can also have many other specific implementation manners. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present utility model.
