Description

Technical Field

[0001] The utility model relates to the technical field of position-limiting plug-in fixtures, in particular to a position-limiting plug-in fixture. Background Art

[0002] Jigs are a broad category of tools used in carpentry, ironwork, locksmithing, mechanics, electronic control, and other crafts, primarily to assist in controlling position or motion. Jigs can be categorized into three types: process assembly jigs, project testing jigs, and circuit board testing jigs. During soldering of circuit boards, the unique structure of the materials can easily cause them to skew, leading to post-solder misalignment and affecting assembly and testing, potentially resulting in product failure. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the present invention provides a position limiting insertion fixture, which solves the problem of preventing the material from being easily skewed after insertion and causing the material to be misplaced after welding.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A limited insertion fixture comprises a fixture housing, a placement slot is defined in the fixture housing, a cover is installed in the placement slot, a positioning device is installed on the fixture housing and the cover to prevent the material from tilting during insertion, and a limiting device is installed on the fixture housing to limit the position of the circuit board;

[0006] The positioning device includes multiple groups of material welding ports opened in the placement groove, and the cover plate is provided with multiple groups of material limiting ports used in conjunction with the material welding ports.

[0007] Preferably, the limiting device includes multiple sets of fastening screws fixedly mounted on the placement slots, and springs are sleeved on the fastening screws.

[0008] Preferably, a pressure block is slidably mounted on the fastening screw, the spring is located between the fastening screw and the pressure block, and a connecting rod is fixedly mounted on the pressure block.

[0009] Preferably, a connecting device is installed on the fixture housing and the cover plate, and the connecting device includes three groups of positioning columns fixedly installed on the cover plate, and the fixture housing is provided with positioning holes used in conjunction with the positioning columns.

[0010] Preferably, the fixture housing and the cover plate are made of synthetic stone.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model sets a positioning device, installs a cover plate on the fixture housing and presses the circuit board, inserts the plug-in material into the circuit board through the material welding port and passes through the circuit board into the material limiting port, limits the plug-in material, and welds the plug-in material to the circuit board through the material welding port, thereby avoiding the situation where the material is easily skewed after insertion and causes the material to be misplaced after welding, preventing product scrapping and reducing the productivity of defective products.

[0013] 2. The utility model sets a limit device. After aligning the position on the circuit board where welding is required, the connecting rod is rotated to drive the pressure block to rotate. When it moves to the position of the circuit board, the connecting rod is moved upward to drive the pressure block to move. The spring is forced to contract. When the pressure block is placed on the circuit board, the connecting rod is released. Under the action of the spring, the pressure block is reset and pressure is applied to the edge of the circuit board. The circuit board is limited by multiple sets of limit devices to prevent the circuit board from being displaced during welding, which causes the plug-in material to be offset.
