Description

Technical Field

[0001] The present invention relates to the technical field of blood oxygen sensor equipment, and in particular to a lead frame structure of a blood oxygen sensor packaging component. Background Art

[0002] The blood oxygen saturation sensor is an instrument for measuring the oxygen concentration in human blood, namely the blood oxygen saturation. The sensor consists of two light-emitting tubes and a photoelectric tube. It can timely understand the oxygen content in the blood during surgical operations or monitoring of critically ill patients.

[0003] The existing lead frame is generally set on the bottom wall of the sensor housing. When the housing is deep, the operator will be disturbed by the housing end and internal components when collecting the wires into the lead frame. In addition, the narrow operating space in the housing cannot ensure the combing effect of the wires. Once the unfixed wires are lifted up, they will interfere with the packaging of the sensor housing. That is, the wires are between the two shells and affect the mutual closure.

The surface of the extrusion rod is in contact with the surface of the force-bearing block.

[0017] The present invention has the following beneficial effects:

[0018] By setting the support mechanism in the present invention, when assembling the sensor, first place the connecting wire inside the placement ring, and then start the motor to drive the transmission rod to rotate. When the transmission rod rotates, it drives the bidirectional screw to rotate. While the bidirectional screw rotates, the connecting rods move towards each other. When the connecting rods move, they drive the driven rods to move. While the connecting rods drive the driven rods to move, they also drive the sliding plates to move towards each other. When the sliding plates move, they push the lifting rods and make the lifting rods extend upward. When the lifting rods extend, they push the placement ring at the end upward. When the lifting rods reach a certain position, they are limited by the limit springs, effectively placing and raising the connecting wire, solving the problem of affecting the closing of the sensor, and improving the working efficiency for workers.

[0019] By setting the limiting mechanism in the present invention, when the driven rod moves, it drives the moving plate to slide towards each other on the inner wall of the chute rod. The moving plate drives the retractable rod to move. When the moving plate moves, it pushes the lower pressing plate to move. When the lower pressing plate receives the thrust, it pushes the slider downward and makes the slider slide downward on the inner wall of the chute plate. When the slider slides, it pushes the passive rod to move downward. The passive rod pushes the sliding plate to move downward. When the sliding plate moves downward, it pulls the pulling plate towards each other through the fixed frame. When the pulling plate moves, it pulls the clamping plate to move towards each other on the surface of the sliding plate. When the clamping plate moves, it drives the limiting rod to move. The limiting rod pushes the clamping ring to move towards each other. When the clamping ring touches the connecting wire, it conducts limiting, effectively limiting connecting wires with different diameters and preventing the connecting wires from slipping.

[0020] In the present invention, by providing a stretching mechanism, when the contraction rod moves, it drives the sliding rod to move towards each other along the inner wall of the moving groove. When the sliding rod moves, it squeezes the elastic plate. When the elastic plate is squeezed, the middle part bends. When the elastic plate bends, it drives the extrusion rod to move backward. When the extrusion rod moves, it squeezes the force-bearing block. When the force-bearing block is subjected to the squeezing force, it pushes the moving rod to slide on the surface of the guide rail. When the moving rod moves, it drives the fixed ring to move and contract the contraction piece, fixing the connection line. When the moving rod moves, the electric push rod is activated to push the vertical plate to move. When the vertical plate moves, it drives the forward plate to slide forward along the inner wall of the sliding groove. When the fixed ring fixes the connection line, the electric push rod pulls the vertical plate backward to make the vertical plate slide backward, and the connection line is pulled backward as a whole, effectively straightening the connection line and preventing the connection line from bending, thus affecting the efficiency of the worker's closing operation of the sensor.

[0021] Of course, when implementing any product of the present invention, it is not necessarily required to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
