Detailed Description

Referring to fig. 1 to 5, the improved terminal assembly 1 of the present invention comprises: at least one improved terminal 10, which has a terminal body 100, wherein one side of the terminal body 100 is extended to form a plurality of contact spring pieces 101, the other side is formed with an upper fixing clip 102 and a lower fixing clip 103 which are symmetrical, a gap 104 is formed between the upper fixing clip 102 and the lower fixing clip 103, the upper fixing clip 102 and the lower fixing clip 103 are respectively provided with a fixing hole 105 penetrating through the upper fixing clip 103 and the lower fixing clip 104 at a proper position, and the fixing hole 105 is extended to the direction of the gap 104 to form a protrusion 106 with a proper height; at least one combination terminal 11; a combination piece 110 is extended from one side of the base plate, and a combination hole 111 penetrating the combination piece 110 is formed on the combination piece 110; and at least one fixing member 12; wherein, the assembly piece 110 of the assembly terminal 11 is disposed in the gap 104 between the upper fixing clip 102 and the lower fixing clip 103 of the improved terminal 10, and the fixing member 12 sequentially passes through the fixing hole 105 of the upper fixing clip 102, the assembly hole 111 of the assembly terminal 11 and the fixing hole 105 of the lower fixing clip 103, so as to combine and fix the improved terminal 10 and the assembly terminal 11.

In summary, the contact spring 101 of the improved terminal 10 includes an auxiliary spring 1011 located in the middle and a main spring 1012 located on both sides, the length of the auxiliary spring 1011 is longer than that of the main spring 1012, the width is narrower than that of the main spring 1012, and the auxiliary spring 1011 and the main spring 1012 are two sets and arranged up and down on one side of the improved terminal 10, and the fixing holes 105 and the protrusions 106 of the upper fixing clip 102 and the lower fixing clip 103 of the improved terminal 10 are circular.

In addition, the assembled terminal 11 is a round terminal, and the assembled hole 111 of the round terminal is the same as the size of the fixing hole 105 of the improved terminal 10; the fastener 12 is a two-piece fastener and is a bolt and nut.

Further, the improved terminal 10 of the present invention has a plurality of contact spring strips 101, one set of which has a sub spring strip 1011 and two main spring strips 1012, because of the number relationship, when actually contacting other terminals, the effect of multi-point contact can be achieved, and the contact quality can be increased, in addition, the sub spring strip 1011 and the main spring strip 1012 can present a shape similar to a "mountain", when contacting other terminals, the sub spring strip 1011 will contact first and then the main spring strip 1012 will contact, so as to disperse the insertion force and reduce the influence caused by the arc effect, therefore, the electric connector can be inserted and pulled out simultaneously when in the power-on state, and it is not necessary to insert and pull out after power-off as in the conventional technology to avoid the damage caused by excessive current.

The protrusions 106 of the upper fixing clip 102 and the lower fixing clip 103 of the improved terminal 10 can increase the contact area and the clamping force between the upper fixing clip and the lower fixing clip 11 when the improved terminal is locked with the combined terminal 11, so as to achieve a better fixing effect between the upper fixing clip and the lower fixing clip and improve the use efficiency.

The foregoing is by way of example only, and not limiting. All equivalent modifications and variations without departing from the spirit and scope of the present disclosure are intended to be included within the scope of the appended claims.
