Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model.

In the description of the present utility model, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Referring to fig. 1 to 3, a terminal clamping device comprises a pneumatic finger 1 and two clamping jaws 2. Two clamping jaw 2 install respectively in pneumatic finger 1 output both sides, clamping jaw 2 includes: a mounting portion 21, the mounting portion 21 being connected to an output end of the pneumatic finger 1; and a clamping part 22, wherein the clamping part 22 is connected to the mounting part 21, a yielding groove 221 is arranged on the clamping part 22, and the clamping part 22 is contacted with the terminal 3. The arrangement of the relief groove 221 realizes that when the clamping jaw 2 clamps the terminal 3 to move downwards during the terminal 3 mounting, the clamping jaw 2 cannot interfere with a capacitor or other components on the main board. The relief groove 221 is formed at the front or rear of the lower portion of the clamping portion, and penetrates the clamping portion from left to right, and the position of the relief groove 211 is set according to the position of other components such as a capacitor on the motherboard. Offer of groove 211 for can avoid parts such as electric capacity that terminal 3 both sides set up when the clamping jaw carries out the centre gripping, compare in the original clamping jaw that does not receive interference such as electric capacity of groove 211 of stepping down can only press from both sides the stitch at terminal 3 top, have groove 211 of stepping down, the clamping jaw can go deep down to press from both sides the working of plastics outer wall at terminal 3 bottom, direct contact with the working of plastics outer wall of terminal, compare in can only with the stitch contact, the area of contact of clamping jaw 2 and terminal 3 obviously grow, thereby frictional force grow greatly improves and adds holding force to clamping jaw centre gripping terminal 3, the stability of centre gripping has been improved.
