Description

Technical Field

[0001] The utility model relates to the technical field of connector processing, in particular to a positioning fixture for connector plugging. Background Art

[0002] After the connector is processed, its electrical connection effect needs to be tested. During the test, the connection socket needs to be positioned, and the push connection plug is inserted into the connection socket. During the test, in order to avoid damage to the connection socket and the connection plug, the connection socket is usually fixed, and the accuracy of the connection plug insertion process can be ensured by fixing. At present, the positioning method is screw positioning, which is easy to cause damage to the connection socket during positioning, and the positioning effect is not good. Utility Model Content

[0003] The utility model provides a positioning fixture for connector plugging, which solves the above-mentioned deficiencies in the prior art, solves the problems that the connection socket is easily damaged during positioning and the positioning reliability is poor, and has strong practicality.

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

[0005] A positioning fixture for connector plug-in comprises a base plate with two pairs of guide holes formed on the base plate, a cylinder is installed at the lower end of the base plate, a movable seat is installed at the movable end of the cylinder, a cross plate is installed at the upper end of the movable seat, a pair of connecting plates are hinged at both ends of the cross plate, a convex part is hinged at the other end of the connecting plate, a concave part is provided at the outer end of the convex part, an inclined hole is formed on the concave part, an action rod is passed through the inclined hole, the lower end of the inclined hole extends outwardly obliquely, a pair of mounting convex plates are provided at the upper end of the concave part, a guide through rod is provided on the mounting convex plate, a limiting nut is provided at the upper end of the guide through rod, a middle block is provided at the inner end of the action rod, the middle block is located in the concave part, a pull rod is provided on the middle block, and a pressure plate is provided at the upper end of the pull rod. When the cylinder drives the horizontal plate to move, the concave parts are pulled closer or farther from each other through the connecting plate. When the concave parts move, the pressing plate acts on the connection socket, thereby positioning the connection socket by pressing down. When the pressing plate is positioned, the lower wall of the pressing plate is flat, so it can avoid damage to the connection socket. A concave baffle is installed at one end of the bottom plate to block the end of the connection socket to facilitate the insertion of the connection plug.

[0006] Furthermore, the upper end of the guide through rod extends out of the bottom plate, and the guide through rod not only guides the movement of the concave part, but also acts on the outer wall of the connecting socket through the guide through rod when the guide through rod moves, thereby achieving the positioning effect of the connecting socket.

[0007] Further, a sleeve is sleeved on the pull rod. A spiral groove is formed in the sleeve, and a vertical groove is formed at the lower end of the spiral groove. A limiting rod is arranged on the pull rod, and the limiting rod moves in the spiral groove and the vertical groove. Through the arranged spiral groove and the limiting rod, when the pressing plate moves downward, it can first rotate inward, and then the pressing plate performs a positioning operation on the connection socket, so as to facilitate the placement and positioning operations during the positioning of the connection socket.

[0008] The advantages of the above technical solution are as follows:

[0009] The utility model facilitates the precise positioning operation of the connection socket, and during positioning, damage to the connection socket can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] 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 accompanying drawings.

[0014] Figure 4 The three-dimensional structure of one of the embodiments is shown Figure 3 . DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] As Figures 1 to 4As shown in the figure, a positioning fixture for connector plugging includes a bottom plate 1. Two pairs of guide holes 10 are provided on the bottom plate 1. A cylinder 2 is installed at the lower end of the bottom plate 1. A movable seat 20 is installed at the movable end of the cylinder 2. A cross plate 21 is installed at the upper end of the movable seat 20. A pair of connecting plates 22 are respectively hinged at both ends of the cross plate 21. The other end of the connecting plate 22 is hinged with a convex part 24. A concave part 25 is provided at the outer end of the convex part 24. An inclined hole 26 is provided on the concave part 25. An actuating rod 27 is inserted into the inclined hole 26. The lower end of the inclined hole 26 extends obliquely outward. A pair of mounting convex plates 6 are provided at the upper end of the concave part 25. A guide through rod 36 is provided on the mounting convex plate 6. A limit nut 37 is provided at the upper end of the guide through rod 36. The upper end of the guide through rod 36 extends out of the bottom plate 1. A middle block 28 is provided at the inner end of the actuating rod 27. The middle block 28 is located inside the concave part 25. A pull rod 29 is provided on the middle block 28. A pressing plate 31 is provided at the upper end of the pull rod 29. A sleeve 33 is sleeved on the pull rod 29. A spiral groove 34 is provided on the sleeve 33. A vertical groove 35 is provided at the lower end of the spiral groove 34. A limit rod 32 is provided on the pull rod 29. The limit rod 32 moves in the spiral groove 34 and the vertical groove 35.

[0016] A concave baffle 4 is installed at one end of the bottom plate 1.

[0017] During the operation of this embodiment, the operator places the connection socket on the bottom plate 1, with the groove of the connection socket facing outward when placing.

[0018] After placing, start the cylinder 2. Driven by the cylinder 2, the cross plate 21 moves. When the cross plate 21 moves, it will drive the included angle between the connecting plates 22 to decrease. When the included angle between the connecting plates 22 decreases, it will cause the concave parts 25 to approach each other. When the concave parts 25 approach each other, they will act on both sides of the connection socket through the guide through rods 36. And when the concave parts 25 move, the inclined holes 26 will act on the actuating rods 27, causing the actuating rods 27 to move downward. As the actuating rods 27 move downward, the pull rods 29 will pull the pressing plates 31 downward. And when the pressing plates 31 move downward, under the action of the spiral grooves 34 and the limit rods 32, the pressing plates 31 will first rotate inward. As the pressing plates 31 continue to move downward, they will act on the upper side of the connection socket through the pressing plates 31 to position the connection socket.

[0019] Then place the connection plug at the outer end of the connection socket and perform the test operation on the electrical connection effect.

[0020] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
