DETAILED DESCRIPTION
[0038] The following will be described in detail below with reference to the accompanying Figures 2-6 The application will be further described in detail.
[0039] An embodiment of the application discloses a wiring terminal.
[0040] Reference will be made to Figure 2 and Figure 3 A wiring terminal comprises an insulating shell 1, a clamping piece 2 and a compression assembly 3. The insulating shell 1 comprises a first shell 11 and a second shell 12, and the two shells are fixed by clamping cooperation. The first shell 11 has a first insertion hole 111 for inserting a wire, and the second shell 12 has a second insertion hole 121 for inserting a pin.
[0041] The first shell 11 is a rectangular shell as a whole, and the first shell 11 is provided with clamping grooves 112 on opposite two side walls away from the first jacks 111. The clamping grooves 112 are communicated to the inner cavity of the first shell 11. The second shell 12 is provided with clamping blocks 122 matched with the clamping grooves 112 on two side walls away from the second jacks 121. The clamping blocks 122 are trapezoidal blocks as a whole, and are provided with first guide inclined surfaces 1221 on one side facing the first shell 11. The first shell 11 is provided with second guide inclined surfaces 1121 matched with the first guide inclined surfaces 1221 on the opening side wall facing the second shell 12. When the second shell 12 is inserted, the clamping blocks 122 on two sides can be pressed towards each other by the cooperation of the first guide inclined surfaces 1221 and the second guide inclined surfaces 1121, so as to facilitate the insertion of the clamping blocks 122 into the first shell 11.
[0042] The wiring terminal is fixed with external equipment through the first shell 11, and the first shell 11 is integrally provided with two opposite mounting supports 113 having through holes for bolts to pass through.
[0043] Referring to Figure 4 In other embodiments, the wiring terminal can be fixed with external equipment through the second shell 12, and the second shell 12 is integrally provided with two mounting lugs 123 on opposite two sides for clamping cooperation.
[0044] The compression assembly 3 is arranged in the first shell 11 as a whole. In this embodiment, the first shell 11 has eight first jacks 111, which are evenly divided into two groups and located on two sides of the first shell 11, i.e. the first shell 11 has eight mounting cavities 114 for mounting the compression assembly 3. The second shell 12 has cavities 122 corresponding to the mounting cavities 114 one by one.
[0045] Referring to Figure 5 and Figure 6 The compression assembly 3 includes a wire blocking plate 31 and a spring 32, and the wire blocking plate 31 and the spring 32 are integrally arranged. The wire blocking plate 31 includes a wire blocking main body 311 abutting against the side wall of the mounting cavity 114 and an abutting portion 312 arranged on one side of the wire blocking main body 311. The spring 32 is located on one side of the wire blocking main body 311 away from the abutting portion 312. The spring 32 is an arc-shaped piece as a whole, and has a deformation portion 321 facing the abutting portion 312. The abutting portion 312 is provided with a first inclined surface 3121 on the end facing the first jack 111, so as to facilitate the insertion of the compression assembly 3 from the opening end of the mounting cavity 114.
[0046] In order to ensure the stability of the compression assembly 3 in the installation chamber 114, the first shell 11 has one side of the blocking line body 311 abutting against a first limiting surface 1141, and the second shell 12 has the other side of the blocking line body 311 abutting against a second limiting surface 124. When the two shells are clamped, the blocking line body 311 is limited by the two limiting surfaces, thereby improving the stability of the compression assembly 3 in the first shell 11.
[0047] The clamping piece 2 includes a clamping line portion 21 arranged in the second shell 12 and a connecting portion 22 inserted into the installation chamber 114 and abutting against the compression assembly 3. The connecting portion 22 is in the form of a plate as a whole, is inserted into the installation chamber 114, and is attached to one side end surface of the abutting portion 312 toward the elastic sheet 32. Therefore, after the wire is inserted into the first insertion hole 111, the wire is compressed on the connecting portion 22 by the deforming portion 321, and the two sides of the connecting portion 22 are respectively abutted against the wire and the abutting portion 312, thereby ensuring the current flow. The end portion of the connecting portion 22 further has a second inclined surface 221, and the inclination directions of the second inclined surface 221 and the first inclined surface 3121 are opposite.
[0048] The side wall of the connecting portion 22 is provided with a clamping side groove 222, and the blocking line body 311 has a clamping waist portion 3111 matched with the clamping side groove 222. Through the cooperation of the clamping side groove 222 and the clamping waist portion 3111, the probability of slippage of the clamping piece 2 is reduced.
[0049] The width of the installation chamber 114 is greater than the width of the connecting portion 22, so that the connecting portion 22 can slide horizontally after being inserted, and the clamping side groove 222 and the clamping waist portion 3111 are matched and inserted.
[0050] The clamping line portion 21 includes two clamping line sheets. In order to ensure that the pin can be inserted between the two clamping line sheets after being inserted into the second insertion hole 121, the second shell 12 has a supporting portion 125 for inserting the clamping line portion 21, and the supporting portion 125 is located between the two clamping line sheets and plays a positioning role on the clamping line portion 21, so that the two clamping line sheets have a gap for inserting the pin, and the gap corresponds to the second insertion hole 121.
[0051] The first shell 11 is provided with a driving hole 115 communicated to the installation chamber 114 at one side of the first insertion hole 111, and the first shell 11 is slidably installed with a driving block 4 for pushing the deforming portion 321 in the driving hole 115. The driving block 4 and the driving hole 115 are limited and matched, so that in the normal state of the elastic sheet 32, the driving block 4 can only slide toward the second shell 12.
[0052] The implementation principle of the wiring terminal is that the compression assembly 3 and the clamping piece 2 are sequentially installed, the compression assembly 3 and the clamping piece 2 are fixed through the cooperation of the clamping side groove 222 and the clamping waist portion 3111, the second shell 12 and the first shell 11 are clamped and fixed, and finally the driving block 4 is inserted from one side of the first insertion hole and abuts against the elastic sheet 32.
[0053] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, and thus: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
