Embodiment Construction

[0019] Attached below figure 1 ~ 5 further elaborates the present invention in conjunction with embodiment. However, it should not be understood that the scope of the subject matter of the present invention is limited to the following embodiments, and all technologies implemented based on the contents of the present invention belong to the scope of the present invention.

[0020] as attached figure 1 As shown, connect the female terminal (2) and the wire (3) by cold pressing, and then insert it into the plug insulator (1) as a whole. as attached image 3 And attached Figure 4 As shown, since the elastic legs (12) are provided on the left and right sides of the insulator (1), and the bayonets (14) are provided on the left and right sides of the female terminal (2), after the female terminal (2) is inserted It can be stuck in the plug insulator (1), even if the wire (3) is pulled to a certain extent, the female terminal (2) will not come out from the insulator (3).

Abstract

The invention discloses a low-cost miniature plug for wiring terminals, comprising a plug insulation (1), a female terminal (2) and a cable (3). The female terminal (2) and the cable (3) are first connected by cold pressing, and then the female terminal (2) and the cable (3) are integrally inserted into the plug insulation (1), and the elastic legs (12) on the insulation (1) are clamped into the bayonet on the female terminal (2), so that the insulation (1), the female terminal (2) and the cable (3) are fixedly connected as a whole, thereby forming a monolithic plug. Secondly, the plug assembly can be spliced by the dovetail through-groove (10) and the dovetail (11) on the plug insulation (1). Compared with the existing plug of the same type, the plug of the invention has higher connectionrigidity, more reliable connection, more flexible insertion and withdrawal mode, smaller structure size and lower cost.

Description

technical field [0001] The invention relates to the field of design and manufacture of electrical connection products, in particular to a low-cost small plug used for terminal blocks. Background technique [0002] The pluggable terminal block is used in conjunction with the plug, and its wiring method is flexible, convenient and fast. Therefore, this type of terminal is more and more favored by customers in the domestic and foreign electrical union product markets. The plug is an indispensable component for the plug-in terminal to exert its superior performance, so the cost performance of the plug plays a decisive role in the cost performance of the whole set of terminals. [0003] At present, popular plugs on the market are mainly connected by means of screw crimping, and the plug insulator needs to accommodate components such as screws, crimping frames, and conductive sheets. Due to the large number of components, not only the cost of the plug is very high, but also the v...
