Advantageously, be provided with bend between one end of body and each pin, pin extends towards the direction away from described body from bend, and each pin is roughly parallel to the plane of described body, and therefore described in use body and described pin insert in the plane that is parallel to each other.
Advantageously, described bend comprises that the middle part of the end that is positioned at described body is to the both sides of bent intermediate portion that a side is extended and the end that is positioned at described body and two edgewise bend portions of extending to opposite side, the said structure form is easy to be shaped, and has excellent structural stability.
Advantageously, each bend is roughly L-shaped.Certainly, according to actual needs, described bend also can change, or takes any other suitable geometry.
Advantageously, described body is tabular.
Advantageously, the quantity of described pin is three, and it lays respectively at the end of described bent intermediate portion and described two edgewise bend portions, plane and plane, described body place approximate vertical that described pin is determined.According to the bikini fixation principle, this structural design has best stability.
Advantageously, described pin is arranged abreast in the both sides that are arranged in described body and with parallel plane two planes of described body.
Advantageously, two pins that are positioned at the end of described two edgewise bend portions equate apart from the distance of the pin of the end of described bent intermediate portions.
Advantageously, described body and described bend are Unitarily molded integral type member.Perhaps, as an alternative, the member of described bend for forming from described body bending.
Compared with prior art, power terminal of the present utility model not only compact conformation, take up room little, and manufacture very simple, convenient, in use without any need for being threaded.And this power terminal is enough firm under confined state, can resist any vibration or the impact that occur in the use effectively.In addition, power terminal of the present utility model can be widely applicable for various operational environments, is particularly useful for carrying out between printed circuit board (PCB) and power source big current delivery.
Description of drawings
By below in conjunction with the detailed description of accompanying drawing, will help to understand more clearly and completely further feature of the present utility model, details and advantage about embodiment of the present utility model.Wherein:
Fig. 1 shows the stereogram according to the power terminal of preferred embodiment of the present utility model;
Fig. 2 shows the end view of power terminal shown in Figure 1;
Fig. 3 shows the upward view of power terminal shown in Figure 1;
Fig. 4 shows the front view of power terminal shown in Figure 1.
Embodiment
Describe the utility model in detail below by one exemplary embodiment.Be pointed out that, those skilled in the art will readily appreciate that following examples are some one exemplary embodiment about method of the present utility model for providing with way of example only, it does not also mean that the utility model is carried out any restriction.
Describe preferred embodiment of the present utility model in detail by means of Fig. 1-4 below, wherein Fig. 1 shows the stereogram according to the power terminal of preferred embodiment of the present utility model, and Fig. 2-4 shows end view, upward view and the front view of power terminal shown in Figure 1 respectively.
Shown in Fig. 1-4, comprise plate-like body 1 and a plurality of bends 2,3,4 that extend from described body 1 according to the power terminal of an one exemplary embodiment of the present utility model, described bend 2,3,4 extends along the direction away from body from body 1 is terminal.The end of bend 2,3,4 has the parallel plane pin 5,6,7 with described body 1 place respectively.The Plane intersects at pin 5,6,7 determined planes and body 1 place, as shown in fig. 1, each bend is roughly L-shaped, and it also can be with other suitable form bending certainly.
