Description

Technical Field

[0001] The utility model relates to the technical field of connector processing, in particular to a pin pliers for connectors. Background Art

[0002] The pins used on connectors are generally inserted into an injection-molded housing by insertion. Of course, some are also directly injection-molded and fixed together. For the former, during the plugging operation, an automatic insertion device is mostly used for insertion, and after insertion, AB glue is used for fixing the pins. However, after automatic insertion, there are always problems such as some pins not being inserted or the insertion length being insufficient. Therefore, it is necessary to later extract and re-insert the pins on this part of the product. During the re-extraction and other operations, the pins are usually extracted by pushing or using a pair of needle-nose pliers, and then the pins are re-inserted. However, in actual operation, due to the limited space of the connector, it is very difficult to hold and extract the pins with a pair of needle-nose pliers. For example, during extraction, only the tip part of the needle-nose pliers can be used to hold the pins, but the clamping effect of the tip is poor, so it is not conducive to the extraction operation. Moreover, during the re-insertion operation, since the pins cannot be accurately clamped, it is inconvenient to perform the re-insertion operation. Content of the Utility Model

[0003] The utility model provides a pin pliers for connectors to solve the above-mentioned deficiencies of the prior art, solve the problem of inconvenient pin extraction and replacement operations, and has strong practicability.

[0004] In order to achieve the purpose of the utility model, the following technologies are proposed:

[0005] A pin pliers for a connector, comprising an upper plate. A pair of guide holes are respectively opened at both ends of the upper plate. A movable rod is inserted through the guide holes. A limit nut is provided at the upper end of the movable rod, and the limit nut is located on the upper side of the upper plate. A movable block is provided at the lower end of the movable rod at the same end, and the movable block is located on the lower side of the upper plate. A movable plate is provided at the lower end of the movable block. An inclined hole is opened at the upper end of the movable plate, and the upper end of the inclined hole extends inwardly. A movable push rod is inserted through the inclined hole. Movable outer plates are respectively provided at both ends of the movable push rod, and push rods are respectively installed on the movable outer plates. The push rods penetrate through the upper plate, and a pressing plate is provided at the upper end of the push rods. A connecting arm is provided at the lower end of the movable plate. A clamping block is provided on the inner wall of the lower end of the connecting arm, and a clamping groove is formed on the inner wall of the clamping block. Through the provided pressing plate, when it moves inward, the push rod will be made to move inward. When the push rod moves inward, the movable push rod will act on the inclined hole, and under the movement of the movable push rod, the movable plates will approach each other, and the pin will be clamped and constrained by the clamping blocks on the connecting arm. This operation method is more convenient to operate compared to the opening and closing of a pair of needle-nose pliers during rotation, and the clamping block requires less moving space, thus facilitating the extraction and insertion operations of the pin in a narrow space.

[0006] Further, lugs are respectively provided on both sides of the upper plate. Through the setting of the lugs, it is convenient for the operator to press the pressing plate.

[0007] Further, the outer end of the lug is of an arc-shaped structure to prevent scratching the hand of the operator.

[0008] Further, the clamping groove is of an arc-shaped structure to improve the positioning effect on the pin, so as to facilitate the implementation of the pin insertion and extraction operations.

[0009] Further, the clamping groove is of a V-shaped structure to expand the clamping and limiting range. Of course, its clamping effect is relatively poor because its clamping area is smaller compared to the arc-shaped structure.

[0010] Further, the width of the connecting arm is smaller than the width of the movable plate to expand the applicable range.

[0011] Further, a vertical rod is provided on one of the lugs, and a hook is bent at the upper end of the vertical rod. Through the hook, it is convenient to straighten the bent pin, thus facilitating the extraction operation of the deformed and bent pin.

[0012] Further, the outer end of the hook is of a tapered structure to facilitate the lifting of the pin.

[0013] Further, a spring is sleeved on the upper end of the push rod, and the spring is located between the pressing plate and the upper plate. The setting of the spring can automatically cancel the clamping when the acting force is cancelled.

[0014] The advantages of the above technical solutions are as follows:

[0015] The utility model facilitates the clamping and positioning of the pin during extraction, improves the positioning effect of the pin during clamping, and ensures the reliability during insertion and extraction. Description of the Drawings

[0016] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings.

[0017] Figure 1 The three-dimensional structure diagram of one of the embodiments is shown. Detailed Description of the Embodiment

[0018] As Figure 1 shown, a pin clamp for a connector includes an upper plate 1. Lugs 11 are respectively arranged on both sides of the upper plate 1. The outer ends of the lugs 11 are arc-shaped structures. A pair of guide holes 10 are respectively opened at both ends of the upper plate 1. A movable rod 2 is inserted through the guide holes 10. A limit nut 20 is arranged at the upper end of the movable rod 2. The limit nut 20 is located on the upper side of the upper plate 1. A movable block 21 is arranged at the lower end of the movable rod 2 at the same end. The movable block 21 is located on the lower side of the upper plate 1. A movable plate 22 is arranged at the lower end of the movable block 21. An inclined hole 25 is opened at the upper end of the movable plate 22. The upper end of the inclined hole 25 extends inwardly. A movable push rod 3 is inserted through the inclined hole 25. Movable outer plates 30 are respectively arranged at both ends of the movable push rod 3. Push rods 31 are respectively installed on the movable outer plates 30. The push rods 31 penetrate through the upper plate 1. A pressing plate 32 is arranged at the upper end of the push rod 31. A spring 33 is sleeved on the upper end of the push rod 31. The spring 33 is located between the pressing plate 32 and the upper plate 1. A connecting arm 23 is arranged at the lower end of the movable plate 22. The width of the connecting arm 23 is smaller than the width of the movable plate 22. A clamping block 24 is arranged on the inner wall of the lower end of the connecting arm 23. A clamping groove is formed on the inner wall of the clamping block 24. The clamping groove is an arc-shaped structure or a V-shaped structure.

[0019] A vertical rod 34 is arranged on one of the lugs 11. A hook 35 is bent at the upper end of the vertical rod 34. The outer end of the hook 35 is a tapered structure.

[0020] During the extraction and insertion of this embodiment, since there are only differences in the insertion and extraction actions, based on this, this embodiment will be described by taking the extraction of the pin as an example.

[0021] When extracting the pin, the operator moves the clamping block 24 to the position of the pin.

[0022] Then, the finger part acts on the lug 11, and the palm part acts on the pressing plate 32.

[0023] Then press the pressing plate 32 inward so that the pressing plate 32 approaches the upper plate 1, and the spring 33 is compressed. When the pressing plate 32 moves, the movable push rod 3 will act on the inclined hole 25, and under the action of the movable push rod 3, the clamping block 24 will move towards the pin, and finally the pin will be positioned through the clamping groove.

[0024] After the pin is positioned, the operator pulls out the pin outward. And in order to improve the stability during clamping, anti-slip patterns can be provided on the inner wall of the clamping groove.

[0025] After pulling out, cancel the force on the pressing plate 32 and cancel the clamping of the pin.

[0026] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
