Problems solved by technology

[0003] Because the pressing tongue part 12 is relatively fragile in structure, it is easy to break from it due to excessive pressing by the user or unexpected external force impact, and because the general terminal block is welded on the circuit board 19 during application, once it is damaged, it will be damaged. Very inconvenient to replace
[0004] Furthermore, the existing pressing part 121 only has a circular depression in the middle, and needs to be matched with a specific needle (not shown in the figure) for pressing, which is inconvenient to use.

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] refer to figure 2 , image 3 and Figure 4 , the preferred embodiment of the terminal block of the present invention is suitable for connecting a wire 7 with a conductive end 71 that removes insulation, and the terminal block includes a lead frame 2, an insulating shell 3 and an identification block 4, wherein the The lead frame 2 is made of metal, and the insulating shell 3 is made of plastic.

[0033] The lead frame 2 includes a base plate 21, and two clamp elastic pieces 22 arranged on the base plate 21. The base plate 21 has two flanges 211 for fitting into the insulating shell 3. The clamp elastic pieces 22 are respectively There is a clamping part 221 suitable for clamping the conductive end 71 of the wire 7 and a pressing part 222 extending away from each other from the clamping part 221. The hook 223 of the shell 3 .

Abstract

A connection terminal includes a lead frame and an insulating housing. The lead frame includes a substrate and two clamping spring plates. The insulating housing includes a guide port which allows insertion of the lead, a tongue depressor part with a free end, and a limiting block. When the free end of the tongue depressor part is pressed, support parts of the clamping spring plates are pressed, and a safety margin position of the free end when pressed is to abut the limiting block. The support parts of the clamping spring plates are pressed by the free end and are far from each other so as to loose the clamping strength to the conductive terminal of the lead. By designing the limiting block, the motion distance of the free end is limited when pressed, the tongue depressor part is avoided to be damaged due to over-press, thereby prolonging the service life of the product and increasing the convenience in usage.

Description

technical field [0001] The invention relates to a terminal block, in particular to a terminal block capable of reducing damage due to excessive pressing or external impact. Background technique [0002] refer to figure 1 , is an existing terminal block suitable for connecting two wires 18, the terminal block includes two inlets 11 for inserting the wires 18 respectively, and two pressing tongue parts with a pressing part 121 respectively 12. [0003] Because the pressing tongue part 12 is relatively fragile in structure, it is easy to break from it due to excessive pressing by the user or unexpected external force impact, and because the general terminal block is welded on the circuit board 19 during application, once it is damaged, it will be damaged. It is very inconvenient to replace. [0004] Furthermore, the existing pressing portion 121 only has a circular depression in the middle, and needs to be matched with a specific needle (not shown) for pressing, which is inc...
