Description

Extractor

The present invention relates to an extraction device, in particular to an extraction device that can be easily operated by a user to remove an electronic connector from an electronic connection device.

With the advancement of technology, various electronic products are widely used, bringing great convenience and practicality to modern people's lives. These electronic products usually rely on various electronic connectors (Electrical connectors) or commonly known as connectors for data (signal) transmission and control applications. D-sub (full name: D-subminiature) is one of the common electronic connectors, usually with 9-pin (PIN) or 15-pin D-shaped interface, suitable for serial port and analog signal connection, commonly used in personal computers, industrial control systems or measuring instruments and other electronic connection equipment.

In order to prevent the above-mentioned electronic connector from loosening and falling off after being assembled and plugged into various electronic connection devices, or to prevent poor data transmission, the assembly structure is designed to have a certain degree of tightness and firmness. Therefore, when a user wants to manually remove the above-mentioned electronic hand connector from various electronic connection devices, it is usually difficult. Sometimes, in order to remove it smoothly, the electronic connector must be slightly tilted to the left or right, and shaken back and forth. However, sometimes it is difficult to accurately control the vertical direction to remove it. These operating conditions may cause the PIN pins inside the electronic connector to be skewed or bent due to improper force. In view of these problems, there are currently no special tools or equipment on the market for users to operate to help solve the above problems.

In addition, there is an IC extractor on the market, which has a structural design similar to a tweezer, except that the ends of the two legs have L-shaped hooks. The Republic of China's new patent announcement number TW145813U also discloses an IC extractor with a protective device. With this IC extractor, the user can insert the ends of the two legs into the gap between the IC (Integrated Circuit, IC for short) or commonly known as "chip" and the circuit board, and easily pull the IC out of the circuit board.

However, the structural design of the IC extractor is not applicable to the D-sub and other electronic connectors. The main reason is that the size of the D-sub and other electronic connectors is usually larger than the IC and other electronic parts on the circuit board. Therefore, it is relatively laborious to extract them, and it is not as easy and labor-saving as removing ICs. However, the IC extractor does not have any labor-saving structural design. Secondly, the IC extractor cannot ensure that the user can accurately apply force in the vertical direction during the extraction operation. At best, it can only achieve the function of easy clamping. Therefore, if brute force is used blindly, it is still easy to cause the PIN pins of the electronic connector to be skewed or bent and damaged, and it cannot effectively solve the main problems of the electronic connector being laborious to operate and easy to be damaged during the extraction process.

The present invention provides an extractor, which at least includes a clamping seat, a clamping claw, two guides, a hook handle and a pressing member. The clamping claw has two claws, which can be used to lean against the limiting baffles of the two legs of the clamping seat, and the bottom of each claw is formed with a buckle portion for buckling between an electronic connector and an electronic connection device; the bottom end of the guide is connected to the clamping claw, and the top end extends longitudinally and slides on the top base of the clamping seat; the hook handle is connected to the top end of the guide, and can be hooked upward by the user to drive each guide to link the clamping claw; the pressing member has a pressing portion for the user to press and operate, and a guiding portion that passes through the hook handle and is connected to the base of the clamping seat.

The extractor provided by the present invention has a claw that can be securely inserted between the electronic connector and the electronic connection device. In addition, during operation, the user only needs to press the pressing part of the pressing member with one hand on the one hand, and use the finger to pull the hook handle upward on the other hand to easily pull the electronic connector upward to detach from the electronic connection device. Therefore, not only is the operation very easy, convenient and labor-saving, but it can also ensure that the electronic connector is pulled upward in the vertical direction for detachment, so the operation is very safe and can effectively avoid damage to the pins of the electronic connector during the operation.

In this embodiment, a screw hole 521 is provided at the bottom of the guide portion 52 of the pressing member 50; a first through hole 112 is further penetrated through the side wall plate 10b of the clamp 10 for forming the base 11 and is located between the guide holes 111, and a fastening bolt 113 can be passed through the first through hole 112 and then screwed into the screw hole 521 of the guide portion 52, so as to lock the guide portion 52 of the pressing member 50 to the clamp 10, and the hook handle 40 is restricted to only move vertically up and down between the clamp 10 and the pressing portion 51 of the pressing member 50.

As shown in Figures 1 and 2, the extractor 1 of this embodiment further includes a return spring 60, which is used to be inserted into the guide portion 52 of the pressing member 50, and the two ends of which are respectively pressed against the top of the connecting portion 41 of the hook handle 40 and the bottom of the pressing portion 51 of the pressing member 50, and can be elastically compressed when the hook handle 40 slides upward, and at the same time accumulate elastic restoring force, so that the hook force of the hook handle 40 is released and can be elastically restored to the original state, so as to be used for the next extraction operation.

As shown in FIGS. 5 and 6 , the extractor 1 of the above embodiment can be used to extract an electronic connector 2 from an electronic connection device 3. During operation, the user can first stop the abutting portion 123 at the bottom of each foot portion 12 of the clamp 10 of the extractor 1 on the surface opposite to the electronic connection device 3, and move horizontally along the surface, so that the buckle portion 22 at the bottom of the left and right claw portions 21 of the clamp 20 can be inserted into the gap D until the limit stop wall 122 on the back plate 121 of the clamp 10 abuts against the limit position. After that, the user only needs to press down the pressing part 51 of the pressing member 50 with a suitable part such as the palm or the thumb, and then use two fingers, such as the index finger and the middle finger, to respectively hold the hooks 42 on the left and right sides of the hook handle 40, and then apply force upward to drive the hook handle 40 to slide upward through the guides 30 and the clamping claw 20, so that the electronic connector 2 can be easily and labor-savingly pulled out from the electronic connection device 3.

It should be noted that during the extraction process, the extractor 1 can ensure that the electronic connector 2 can be stably pulled up vertically to prevent the internal PIN pins from being skewed or bent and deformed due to improper force and thus damaged. The main reasons are as follows:

First, the abutment portion 123 at the bottom of each foot 12 of the clamp 10 can remain vertically abutted against the relative portion of the electronic connection device 3, thereby effectively preventing the clamp 10 from deflecting or shaking.

Second, the limiting baffle 122 on the back plate 121 of the clamp 10 can be used to abut against the electronic connector 2, and can also effectively prevent the clamp 10 and the electronic connector 2 from deflecting or shaking.

Third, the clamping claw 20 can be stably limited in the limiting groove 13 of the clamping seat 10 to slide vertically up and down, and can also effectively prevent the clamping claw 20 from deflecting or shaking during the sliding displacement process.

Fourth, the claw 20 can ensure that the claw 20 and the hook handle 40 can slide and move smoothly in the longitudinal direction by means of the guide sliding structure design adopted between the guide member 30 connected on the left and right sides and the base 11 of the clamping seat 10, and the guide sliding structure design adopted between the hook handle 40 and the guide part 52 of the pressing member 50, and can also effectively prevent the claw 20 from deflecting or shaking during the sliding displacement process.

As shown in Figures 7 to 9, the present invention further provides a second embodiment of an extractor. The extractor 1a of this embodiment is roughly the same as the extractor 1 of the first embodiment, and the difference is that the clamp 101 of this embodiment only extends the side wall 10b at the top of the rear side wall 10a, so an opening 14 can be formed at opposite positions on both sides of the clamp 101. Therefore, at least a part or the main purpose of the side wall 10b is to form the base 11. Secondly, at least the rear side wall 10a on both sides is used to form the foot 12 and the back plate 121 respectively, so the foot 12 of this embodiment does not have the design of the side wall 10b, and the purpose is to form the opening 14 or the space for avoidance.

The clamping claw 201 of this embodiment includes two components, rather than a single component. In other words, the clamping claw 201 has two curved plates, each used to form a claw portion 21; the bottom end of each curved plate extends a buckle plate horizontally, each forming the buckle portion 22, and the upper end of each claw portion 21 is formed with a pivot seat 24 pivoted with the bottom end of each guide member 30, for example, through a shaft pin 33 extending through the pivot, can form a rotation fulcrum, and through the design of the rotation fulcrum, the buckle portion 22 of the claw portion 21 can pivotally expand in the direction away from each other, or contract in the direction close to each other to produce a clamping buckle action, as shown in Figure 9.

It should be noted that due to the dimensional tolerances in the production of general electronic connectors, the design of this embodiment allows the electronic connector to be appropriately expanded or contracted through the pivot point when the width of the two sides is slightly larger or smaller, ensuring that each buckle portion 22 can be smoothly buckled and clamped in the gap D from both sides before the subsequent extraction operation. It is easy to understand that even if the types or specifications of electronic connectors are different, as long as they are within the appropriate size range and allow the buckle portion 22 to be smoothly buckled and clamped in the gap D through the above pivot operation, they are all applicable to the extractor 1a of this embodiment.

In summary, this invention has excellent invention practicality among similar products. At the same time, after searching relevant domestic and foreign technical data or patent documents, no similar structure has been found before. Therefore, this invention has the requirements of a new patent, and an application is filed in accordance with the law. However, the above is only a partial feasible embodiment of this invention. Any equivalent structural changes made by applying this invention specification and the scope of patent application should be included in the patent scope of this invention.
