Description

Technical Field

[0001] The utility model relates to the technical field of ceramic insulators, in particular to a ceramic insulator with multi-layer wiring. Background Technique

[0002] A semiconductor package housing is a type of hermetic package, which has a relatively large outer lead pitch and is widely used in hybrid integrated circuits, power devices, and microwave devices. It is suitable for devices with complex functions, multi-chip assembly, and a small number of output pins. The metal package of semiconductor integrated circuits uses metal as the housing or base, and the chip can only be installed on the outer shell or base through the substrate. The leads pass through the metal housing or base and are mostly connected through ceramic insulators as a medium. The above method is a common electronic packaging form of metal sealing technology.

[0003] However, the above packaging form has the following deficiencies: The existing ceramic insulators for ceramic sealing can only install metal housings of one model size. When it is necessary to replace a new model size of metal housing, it is often necessary to replace the ceramic insulators as well, resulting in low work efficiency. At the same time, the installation is not convenient enough, and due to the different lead distances opened by different metal housings, it is necessary to continuously manually adjust the ceramic insulators, which makes the operation cumbersome when the metal housing is combined with the leads for sealing.

[0004] Therefore, we propose a ceramic insulator with multi-layer wiring. Content of the Utility Model

[0005] The purpose of the utility model is to provide a ceramic insulator with multi-layer wiring to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A ceramic insulator with multi-layer wiring, including a bottom plate, a metal housing, a mounting plate, leads, a ceramic insulator, and a connecting rope. A metal housing is installed above the top surface of the bottom plate. Mounting plates are symmetrically and fixedly connected to the front and rear ends of the metal housing. Leads are sequentially installed on both sides of the metal housing. A ceramic insulator is installed on the outer surface of the leads. A connecting rope is installed between the ceramic insulators.

[0007] Preferably, a placement groove is opened on the top surface of the bottom plate. A push rod is installed inside the placement groove. A placement plate is installed on the top surface of the push rod. A push rod motor is installed on the bottom surface of the bottom plate, and the output end of the push rod motor passes through the inside of the bottom plate and is fixedly connected to the push rod. When the push rod motor operates, it drives the push rod to move. The movement of the push rod drives the placement plate to move together. The movement of the placement plate can drive the metal housing to move, so as to adjust the height position of the metal housing, which is convenient for the subsequent installation of the ceramic insulator.

[0008] Preferably, moving grooves are symmetrically formed on the top surface of the bottom plate. A lead screw is rotatably installed in the moving groove. Moving rods are sequentially meshed and installed on the outer surface of the lead screw. A clamping frame is fixedly connected to the top surface of the moving rod. A first rotating cylinder is rotatably installed on the outer surface of the lead screw, and the outer surface of the first rotating cylinder is fixedly connected to one of the moving rods. When the lead screw rotates, it drives the meshed moving rods on the outside to move. The movement of the moving rods drives the clamping frame to move, and the movement of the clamping frame drives the ceramic insulator placed inside to move. Thus, it is possible to adjust the position of the ceramic insulator according to the different lead distances opened in different metal shells.

[0009] Preferably, a second rotating cylinder is rotatably installed on the outer surface of the lead screw. A connecting rod is fixedly connected to the outer surface of the second rotating cylinder, and the other end of the connecting rod is fixedly connected to a pushing plate. The pushing plate can be operated to move. Through the cooperation of the second rotating cylinder and the connecting rod, the pushing plate is used to install the ceramic insulator placed in position into the metal shell.

[0010] Preferably, a pulley is installed on one end surface of the lead screw. A connecting belt is installed between the pulleys. A rotating motor is installed on the surface of the bottom plate on one side of the lead screw, and the output end of the rotating motor is fixedly connected to the lead screw. The connection relationship between the pulley and the connecting belt can be utilized. When the rotating motor operates, it drives the lead screw to rotate, playing a role in transmitting the force of the rotating motor.

[0011] Preferably, the connecting rope is composed of a telescopic and stretchable fiberglass rope. The fiberglass rope has the ability of corrosion resistance and high-strength stretching, which can better facilitate the use of the ceramic insulator.

[0012] Compared with the prior art, the beneficial effect of the present utility model is that through the cooperation of the lead screw and the rotating motor, when the rotating motor operates, it drives the lead screw to rotate. The rotation of the lead screw drives the meshed moving rods on the outside to move. The movement of the moving rods drives the clamping frame installed on the top to move, and the movement of the clamping frame can drive the ceramic insulator in the clamping frame to move. Thus, it can be adaptively adjusted according to the different lead distances opened in different metal shells. BRIEF DESCRIPTION OF THE DRAWINGS
