Novel chip extractor

Technical Field

The utility model relates to a research and development instrument technical field, concretely relates to novel chip pull-out ware.

Background

In the process of developing and debugging a circuit board, a chip inserted into a chip slot of the circuit board is often pulled out and inserted for many times, and in the process of pulling out and inserting, because a pulling-out tool used by an operator cannot guarantee that the stress of the chip is even in the process of pulling out, the pin of the chip is often easily damaged, so that the chip cannot be normally used, a special chip pulling-out tool is needed, the stress of the chip in the process of pulling out is even, and the pin of the chip cannot be damaged.

SUMMERY OF THE UTILITY MODEL

The utility model provides a novel chip pull-out ware through the cooperation of clamp plate and sliding sleeve, has provided to pull out the effort to the chip to avoid the chip to roll over the impaired condition of foot and take place.

In order to achieve the above object, the utility model provides a following technical scheme: a novel chip extractor, comprising: the clamping rods are arranged in pairs and are mutually hinged and matched through the tail parts, and the heads of the two clamping rods are oppositely provided with clamping jaws; the sliding sleeves are arranged in pairs and are respectively matched on the clamping rods in a sliding manner, and one end of each sliding sleeve corresponding to the clamping jaw is respectively provided with a supporting head extending along the length direction; the pressing plates are arranged in pairs and are respectively hinged and matched with the tail parts of the clamping rods through one ends; and the supporting arms are hinged and matched with the free ends of the pressing plates and one end of the sliding sleeve corresponding to the tail part of the clamping rod.

Preferably, each of the jaws is wedge-shaped, and the width of the jaws is slightly less than I C.

Preferably, a torsion spring is arranged between the two clamping rods and used for applying closing force to the two clamping rods; the tail parts of the two clamping rods are respectively provided with a control sheet.

Preferably, a return spring is respectively arranged between each pressure plate and the corresponding clamping rod.

Preferably, a pressing piece is arranged on one side, far away from each sliding sleeve, of each sliding sleeve.

The utility model has the advantages that: through opening the clamping bar, make the jack catch insert in the gap between chip both ends and the socket, guarantee that the clamping bar carries out firm centre gripping to the chip, through pressing two preforming this moment, make the downward propelling movement sliding sleeve of support arm, the support head of sliding sleeve bottom supports PCB to make the articulated position of preforming drive two clamping bars and carry out vertical lifting to the direction of keeping away from PCB, and then take out the chip from the socket. Compare common pull-out ware, fix the chip through hook and preparation, the mode of taking out the chip relying on the vertical motion of hand, this structure can make the chip break away from the socket through the support of self motion part to the atress is balanced stable, is difficult for appearing the problem that the chip stitch was bent. The jack catch has increased the area of contact with the chip, has reduced pressure, avoids damaging the problem on chip surface at the in-process of pulling out, customizes the jack catch of equidimension not according to the standard model specification of chip simultaneously to realize special core dedicated purpose, further improved the fail safe nature that the chip was pulled out. The clamping rod is operated through the control piece, and under the action of the torsion spring, the clamping rod is automatically clamped on the chip, so that the problem that the chip pulled out is not prone to accidentally falling off from the tool is solved. The reset spring ensures that the sliding sleeve is always positioned at the upper end of the clamping rod in a release state, and the sliding sleeve can not be accidentally contacted with the PCB in the process of clamping the chip, so that interference factors are discharged, and a convenient operation process is provided. And the pressing sheet provides stable positioning capability for the chip removal.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is an exploded view of the present invention.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

According to fig. 1 and 2, a novel chip extractor comprises: the clamping rods 1 are arranged in pairs and are mutually hinged and matched through the tail parts, and the heads of the two clamping rods 1 are oppositely provided with clamping jaws 2; the sliding sleeves 3 are arranged in pairs and are respectively matched with the clamping rods 1 in a sliding manner, and one end of each sliding sleeve 3, corresponding to each clamping jaw 2, is provided with a supporting head 4 extending along the length direction; the pressing plates 5 are arranged in pairs and are respectively hinged and matched with the tail parts of the clamping rods 1 through one ends; and the supporting arms 6 are hinged and matched with the free ends of the pressing plates 5 and one end of the sliding sleeve 3 corresponding to the tail part of the clamping rod 1.
