Description

Technical Field

[0001] The utility model relates to the technical field of crystal oscillators, in particular to a crystal oscillator which is convenient for plug-in. Background Art

[0002] A crystal oscillator is an electronic component that uses the piezoelectric effect and inverse piezoelectric effect of a quartz crystal (a single crystal of silicon dioxide as its main component) to generate and maintain a stable oscillation frequency. It plays a vital role in many electronic devices, providing the system with an accurate and stable clock signal, and is the core component of the frequency reference in electronic systems.

[0003] Most of the existing crystal oscillators are fixedly installed with the wiring board by welding. For some equipment that needs to run for a long time and at full load, such as data center servers, uninterruptible power supplies (UPS), industrial control systems, etc., the crystal oscillator may be aged rapidly due to being in high temperature and high load for a long time, and needs to be checked and replaced regularly. When the welded crystal oscillator fails or needs to be replaced, it needs to be desoldered for repair or replacement because it is permanently connected to the circuit board. This not only increases the difficulty of maintenance, but also requires high skills of technicians, and it is easy to damage the circuit board or the new oscillator during the desoldering process. Therefore, a crystal oscillator that is easy to plug in is needed to solve the above problems. Utility Model Content

[0006] A slot is provided on the side of the adapter, a first electrode terminal is provided in the slot, a second electrode terminal corresponding to the first electrode terminal is provided at the bottom of the crystal oscillator body, the crystal oscillator body is inserted into the slot and slidably connected with the adapter, and the adapter and the crystal oscillator body are electrically connected through the first electrode terminal and the second electrode terminal.

[0007] As a preferred crystal oscillator that is easy to plug in according to the utility model, the first electrode terminal is provided with a first reed tongue, a second reed tongue and a third reed tongue, the second electrode terminal is provided with a first contact, a second contact and a third contact, the first reed tongue is perpendicular to the second reed tongue and the second reed tongue, and the second reed tongue is perpendicular to the third reed tongue.

[0008] As a preferred embodiment of the conveniently plug-in crystal oscillator of the utility model, an elastic body is arranged on the top of the heat sink, and the heat sink body and the adapter are elastically slidably connected via the elastic body.

[0009] As a preferred embodiment of the conveniently inserted crystal oscillator of the utility model, the elastic body is an annular hollow rubber ring.

[0010] As a preferred embodiment of the conveniently inserted crystal oscillator of the utility model, a heat sink is provided on the upper end surface of the heat sink.

[0011] As a preferred embodiment of the crystal oscillator of the utility model which is convenient for insertion, a limit strip is arranged at the bottom of the front end surface of the slot.

[0012] As a preferred embodiment of the conveniently inserted crystal oscillator of the utility model, a pull-out plate is provided on the front end surface of the crystal oscillator body, and an arc groove is provided on the bottom of the pull-out plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model provides an adapter at the bottom of the crystal oscillator so that a plug-in connection is adopted between the crystal oscillator and the adapter. When the crystal oscillator body needs to be replaced or maintained, there is no need to perform complicated welding operations. Simply unplug the oscillator body and insert a new oscillator. The plug-in structure allows the crystal oscillator to be easily inserted or unplugged during the test or debugging stage, which is convenient for engineers to quickly replace different oscillators for comparative testing or troubleshooting, thereby improving the work efficiency in the research and development stage. This design greatly simplifies the maintenance process, shortens equipment downtime, reduces maintenance costs, and avoids possible damage to the circuit board caused by welding operations.

[0015] 2. The utility model can provide multi-point contact through the design of the first electrode terminal and the second electrode terminal with three contacts, ensure the stability of the electrical connection, reduce the contact resistance, and reduce the risk of signal distortion or unstable oscillator operation caused by poor contact. At the same time, multi-point contact is also conducive to dispersing current, reducing the thermal stress of a single contact point, and extending the life of the contact.

[0016] 3. The utility model sets an elastically connected heat sink on the top of the adapter, and the heat sink is close to the top of the crystal oscillator body, which can effectively and quickly conduct the heat generated by the oscillator when it is working to the heat sink, and then dissipate the heat to the surrounding environment through the heat sink, thereby reducing the operating temperature of the oscillator, improving its working stability, and extending its service life. The heat sink presses the connection between the crystal oscillator and the adapter, which is equivalent to adding additional mechanical pressing force, which helps to maintain the contact pressure between the first electrode terminal and the second electrode terminal, reduce contact looseness caused by vibration, thermal expansion and contraction, etc., enhance the stability of the electrical connection, reduce contact resistance, and reduce the possibility of signal distortion and failure.

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 5 , a crystal oscillator convenient for plug-in, comprising a crystal oscillator body 1, a transfer seat 2 is arranged at the bottom of the crystal oscillator body 1, and a heat sink 3 is arranged at the top of the transfer seat 2;

[0024] A slot 210 is provided on the side of the adapter 2, a first electrode terminal 110 is provided in the slot 210, a second electrode terminal 230 corresponding thereto is provided at the bottom of the crystal oscillator body 1, the crystal oscillator body 1 is inserted into the slot 210 and is slidably connected to the adapter 2, and the adapter 2 and the crystal oscillator body 1 are electrically connected through the first electrode terminal 110 and the second electrode terminal 230.

[0025] When using the device, first, weld the adapter 2 to the corresponding position on the circuit board, then hold the crystal oscillator body 1, ensure that the second electrode terminal 230 is in the correct direction, align it with the corresponding slot 210 on the adapter 2, and gently insert it sideways. During the insertion process, you should feel a certain resistance, indicating that the first electrode terminal 110 and the second electrode terminal 230 are in good contact. Continue to push until the bottom of the crystal oscillator body 1 is completely in contact with the adapter 2. When disassembling, first disconnect the power supply of the device to ensure that the circuit is powerless, gently grasp the pull-out plate 120 with your hand, and apply force upward steadily and evenly to lift the crystal oscillator body 1 to the upper end of the limit bar 220. Then, pull it outward until the crystal oscillator body 1 is successfully separated from the adapter 2.

[0026] Furthermore, the first electrode terminal 110 is provided with a first reed tongue 111, a second reed tongue 112 and a third reed tongue 113, and the second electrode terminal 230 is provided with a first contact 231, a second contact 232 and a third contact 233. The first reed tongue 111 is perpendicular to the second reed tongue 112 and the second reed tongue 112, and the second reed tongue 112 is perpendicular to the third reed tongue 113.

[0027] The first electrode terminal 110 and the second electrode terminal 230 are connected by three sets of spring tongues and contacts, which greatly improves the contact stability between the first electrode terminal 110 and the second electrode terminal 230 and greatly reduces the probability of virtual connection or open circuit of the crystal oscillator body 1.

[0028] Furthermore, an elastic body 320 is provided on the top of the heat sink 3 , and the main body of the heat sink 3 and the adapter 2 are elastically slidably connected via the elastic body 320 .

[0029] The heat sink 3 is pressed toward the crystal oscillator body 1 by the elastic rubber ring, so that the heat sink 3 fits the crystal oscillator, improving the heat dissipation effect and enhancing the stability of the connection between the first electrode terminal 110 and the second electrode terminal 230 .

[0030] Furthermore, the elastic body 320 is an annular hollow rubber ring.

[0031] The rubber ring has good dustproof and sealing effects, which can reduce the dust falling into the adapter 2 and affect the stability of the equipment. The hollow structure design greatly enhances the elasticity of the rubber ring, so that it can produce a large elastic deformation when subjected to force, thereby facilitating the installation of the crystal oscillator.
