Terminal structure of guillotine-type connector

Abstract

The invention relates to a terminal structure of a guillotine-type connector. The terminal structure comprises at least one first terminal, wherein the first terminals are each provided with two plates in parallel; a front insertion end, a plug tail end and an upper insertion end are formed between the two plates; a bottom plate is connected between the two plates; the plates are each integrally connected with an arc-shaped portion protruding inwardly at the position adjacent to the edges of the front insertion end and the upper insertion end; a first clamping position is formed at the shortest distance between the two arc-shaped portions; the arc-shaped portions are connected with clamping pieces that are flat and extend toward the plug tail end; the gap between the two clamping pieces diminishes gradually from the ends of the arc-shaped portions to the bottom plate and the plug tail end, so that the gap at the position, adjacent to the upper insertion end, between the two clamping pieces is relatively larger than that at the position, adjacent to the end of the bottom plate, between the two clamping pieces, thereby forming a surface-contact conductive state by elastic turning ofthe two clamping pieces.

[0002] A known connection structure of connector terminals, please refer to Figure 13 As shown, the connecting structure of the connector terminal includes a male terminal 60 and a female terminal 70, the female terminal 70 is formed with a fixing frame 71, and a front opening 72 and a rear opening 73 are formed at intervals by the fixing frame 71, the The female terminal 70 is bent inwardly from both sides of the fixing frame 71 to be provided with two arc bending pieces 74, and the arc bending pieces 74 extend from the front opening 72 end to the rear opening 73 end, and the male terminal 60 is formed by two arc bending pieces 74. Insert between the curved pieces 74, and use the curved piece 74 to squeeze the male terminal 60 to form a conductive connection. It is not difficult to find that there are still some deficiencies in the above-mentioned known structure. The main reasons are as follows: the curved piece 74 and the male terminal 60 only form a partial contact equivalent to a line, and its conductive effect and allowable current are obviously insufficient. The composition obviously affects the elasticity difference of the female terminal 70, so the curvature of the curved piece 74 and the gap formed by each batch of material processing will have slight changes, not to mention that the curved piece 74 is bent on one side in the same direction. As a result, the deformation range of the arc bending piece 74 itself is large, which makes it difficult for the arc bending piece 74 formed by processing each batch of materials to maintain the same arc, and this slight change will directly affect the electrical conduction between the male terminal 60 and the female terminal 70. As a result, poor contact will lead to excessive resistance and overheating, and insufficient clamping force will easily cause the problem of self-detachment due to vibration. Moreover, the female terminal 70 is only bent in one direction to set the arc bending piece 74, which is useful for many Permanent deformation will be formed when elastic fatigue or improper operation are caused by repeated plugging. When the gap between the two arc-bent pieces 74 is enlarged, there will also be poor contact and easy to fall off. On the contrary, if the female terminal is excessively increased Clamping force, the insertion resistance between the male terminal and the female terminal will be too large, making it difficult to perform the connection operation, and will accelerate the rapid wear between the male terminal and the female terminal and reduce its durability , this is the technical problem that the present invention intends to improve
