Description

Technical Field

[0001] This utility model relates to the field of crystal oscillator module technology, specifically to a baud rate correction device for communication equipment. Background Technology

[0002] Baud rate, also known as modulation rate, refers to the number of symbols or code elements transmitted per second in a digital communication system. In the modem of a communication device, the transmission rate is determined by the baud rate. In addition to conventional software adjustment, the baud rate can also be corrected by improving the performance of the crystal oscillator module and the clock module. Therefore, we propose a baud rate correction device for communication equipment.

[0003] The existing technology still has the following drawbacks in its use:

[0004] The baud rate correction device in existing communication equipment uses a spring to elastically limit the internal micro-motion structure. However, the spring is a metal spiral structure, which is prone to changes in elasticity due to metal fatigue under long-term use, which in turn leads to changes in the baud rate. Furthermore, it is difficult to repair the spring later, and only the internal module can be replaced, which greatly increases the failure rate of the equipment and the difficulty of later maintenance.

[0005] In existing communication equipment, the baud rate correction device experiences significant resistance during micro-motion because the internal micro-motion structure is a conventional sheet-like object. This makes it difficult to guarantee the accuracy of the crystal oscillator module, thus limiting the applicability of traditional baud rate correction devices.

[0006] In view of this, we propose a baud rate correction device for communication equipment to solve the existing problems. Utility Model Content

[0007] The purpose of this invention is to provide a baud rate correction device for communication equipment to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a baud rate correction device for a communication device, comprising a housing and a micro-motion component, wherein limit bolts are fixedly installed on both sides of the top of the housing, four sets of support rods are fixedly installed inside the housing, and a limit ring is fixedly installed at one end of each support rod, four traction belts are fixedly installed on the inner wall of the housing, and the traction belts are in contact with the limit rings, and an information plate is fixedly installed at the bottom inside the housing;

[0009] A micro-motion component is installed on the inner side of the limiting ring. The micro-motion component includes a piezoelectric ceramic cover. The piezoelectric ceramic cover is fixedly connected to the traction belt on all four sides. A conical cover is installed on the top and bottom of the piezoelectric ceramic cover.

[0010] Preferably, a sealing cover is fixedly installed on the top of the housing, and the sealing cover is engaged with a limiting bolt.

[0011] Preferably, the limiting ring is installed at the center of the inside of the housing, and there is a one-centimeter distance between the limiting ring and the bottom of the inside of the housing.

[0012] Preferably, the bottom of the information board is equipped with two pins extending out of the bottom of the housing, and a sealing ring is fixedly installed at the connection position between the pins and the housing.

[0013] Preferably, a conveyor belt is installed on both sides of the piezoelectric ceramic cover, and the end of the conveyor belt away from the piezoelectric ceramic cover is electrically connected to the information board.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses a strip connected to a micro-motion structure inside the device, and a ring structure to press down on the strip. This causes the micro-motion structure to be pulled by the elastic force of the strip and kept in the center of the shell for micro-motion. In later maintenance, the stress state of the micro-motion structure can be adjusted by adjusting the length of the strip and the degree of pressure of the ring, thereby improving the accuracy and durability of the device during operation.

[0016] This invention reduces the resistance experienced by the piezoelectric ceramic cover during micro-motion by installing a pyramidal cover on the upper and lower sides of the micro-motion structure, thereby improving the accuracy of the device during operation and helping to improve the effect of correcting the baud rate.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 - Figure 5 As shown, the present invention proposes a baud rate correction device for a communication device, comprising a housing 1 and a micro-motion component 2. Limiting bolts 101 are fixedly installed on both sides of the top of the housing 1. Four sets of support rods 104 are fixedly installed inside the housing 1, and a limiting ring 103 is fixedly installed at one end of each support rod 104. Four traction straps 105 are fixedly installed on the inner wall of the housing 1, and the traction straps 105 are in contact with the limiting rings 103. An information plate 106 is fixedly installed at the bottom inside the housing 1. The housing 1 can provide baud rate correction for surrounding components. The installation position is provided by the limit bolt 101, which is used to limit the sealing cover 102 in the horizontal direction to improve the installation stability of the sealing cover 102. The support rod 104 can fix the limit ring 103. The limit ring 103 presses down the traction belt 105, so that the elastic force of the traction belt 105 limits the piezoelectric ceramic cover 201 and improves the convenience of maintenance of the device in the later stage. The information board 106 can connect the piezoelectric ceramic cover 201 and the external circuit, so that the device can be connected to the circuit to correct the baud rate.

[0025] A micro-motion component 2 is installed on the inner side of the limiting ring 103. The micro-motion component 2 includes a piezoelectric ceramic cover 201. The piezoelectric ceramic cover 201 is fixedly connected to the traction belt 105 on all four sides. A conical cover 202 is installed on the top and bottom of the piezoelectric ceramic cover 201. The micro-motion component 2 can obtain the baud rate by the current generated by the piezoelectric ceramic cover 201 when it is micro-moved. The accuracy of the device can be adjusted by adjusting the limiting ring 103 or the traction belt 105 so as to correct the baud rate of the integrated circuit.

[0026] Furthermore, a sealing cover 102 is fixedly installed on the top of the housing 1, and the sealing cover 102 is engaged with the limiting bolt 101. The sealing cover 102 can seal the housing 1, thereby achieving the purpose of waterproofing and dustproofing.

[0027] Furthermore, the limiting ring 103 is installed at the center of the inside of the housing 1, and there is a distance of one centimeter between the limiting ring 103 and the bottom of the inside of the housing 1.

[0028] Furthermore, the bottom of the information board 106 is equipped with two pins 107 extending out of the bottom of the housing 1, and a sealing ring 108 is fixedly installed at the connection position between the pins 107 and the housing 1. The pins 107 enable the information board 106 to be connected to external circuits, thereby connecting the device to an integrated circuit for operation. The sealing ring 108 can provide waterproof and dustproof treatment at the joint between the pins 107 and the housing 1, thereby improving the stability of the device during operation.

[0029] Furthermore, a transmission belt 203 is installed on both sides of the piezoelectric ceramic cover 201, and the end of the transmission belt 203 away from the piezoelectric ceramic cover 201 is electrically connected to the information board 106. The transmission belt 203 can transmit the current generated by the piezoelectric ceramic cover 201, thereby facilitating the information board 106 to detect and collect current information.

[0030] Working principle: The device is soldered to the integrated circuit via pin 107. When the piezoelectric ceramic cover 201 is in operation, it generates micro-motion, which converts mechanical energy into electrical energy to generate an electrical signal. Alternatively, when the piezoelectric ceramic cover 201 is energized, it generates mechanical vibration, which enables the information board 106 to collect baud rate information. During the adjustment process, by adjusting the traction length of the traction belt 105 or the longitudinal position of the limiting ring 103, the resultant force of the traction belt 105 on the piezoelectric ceramic cover 201 is changed, thereby correcting the baud rate and improving the accuracy of the device during operation.

[0031] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
