Description

Technical Field

[0001] The utility model relates to the technical field of optocoupler packaging, in particular to an optocoupler packaging pin structure. Background Technique

[0002] An optocoupler, also known as an opto-isolator or optoelectronic coupler, is simply called an optocoupler. It is a device that transmits electrical signals through light. It has good isolation for input and output electrical signals. Therefore, it is widely used in various circuits. The pins of an optocoupler refer to the devices that extend from both sides of the optocoupler and have the functions of receiving and transmitting information.

[0003] In a patent with the patent publication number CN 218975439 U, an optocoupler packaging pin structure is recorded. The structure includes an optocoupler body. An outer shell is provided outside the optocoupler body. Six mounting holes are provided on both sides of the outer shell. Six pins are provided on both sides of the optocoupler body. The pins pass through the mounting holes and are connected to the optocoupler body. An insulating sleeve is sleeved outside the pins. By setting the insulating sleeve, the pins can be better protected, and at the same time, it also has the effect of blocking external components. However, when the optocoupler needs to be replaced, the solder joints need to be heated to remove the pins from the PCB board, then desolder the solder and reball the pins. Finally, the new optocoupler is soldered to the contacts on the PCB board. The operation is cumbersome and is likely to affect other components on the PCB board, resulting in waste of resources, reducing the convenience of replacing the optocoupler body and the reliability of the optocoupler packaging pin structure, and greatly increasing the packaging failure rate of vehicle optocouplers.

[0004] Based on this, an optocoupler packaging pin structure is now provided to eliminate the drawbacks of existing devices. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the purpose, technical solutions and advantages of the utility model more clear and understandable, the following further describes the utility model in detail with reference to the drawings and embodiments.

[0027] Embodiment 1

[0028] In one embodiment, as Figures 1 - 6As shown, an optocoupler package pin structure includes an optocoupler body 301. A plurality of second pins 300 are symmetrically arranged on the side wall of the optocoupler body 301. An installation block 201 is clamped at the end of the second pin 300. A first pin 200 is fixedly arranged at the bottom of the installation block 201. A first outer shell 100 is sleeved on the top of the optocoupler body 301. A second outer shell 103 is sleeved on the bottom of the optocoupler body 301. Fixing grooves 104 are formed around the top of the second outer shell 103. A fixing rod 105 adapted to the fixing grooves 104 is fixedly arranged at the bottom of the first outer shell 100. The fixing rod 105 is clamped into the fixing grooves 104 to encapsulate and protect the optocoupler body 301 by using the first outer shell 100 and the second outer shell 103, improving the stability of the structure, reducing the production defect rate, and increasing the production capacity. Installation holes 106 are symmetrically formed on the side walls of the first outer shell 100 and the second outer shell 103. The second pin 300 passes through the installation holes 106 and is clamped with the installation block 201. A clamping mechanism and a welding mechanism are also included. A clamping mechanism for facilitating the clamping, loading and unloading of the second pin 300 is arranged on the side wall of the second pin 300. A welding mechanism for rapid welding is arranged at the end of the first pin 200.

[0029] In one embodiment, as Figure 1 shown, a heat sink 101 is arranged on the top of the first outer shell 100. The heat sink 101 can play a role in rapid heat dissipation, avoiding the overload problem caused by high temperature during the use of the optocoupler body 301.

[0030] In one embodiment, as Figures 1 - 4 shown, a plurality of anti-slip strips 102 are symmetrically arranged on the side wall of the first outer shell 100, playing an anti-slip role and facilitating the user to take the optocoupler body 301.

[0031] In one embodiment, as Figures 1 - 6As shown in the figure, the clamping mechanism includes a mounting groove 204, a clamping groove 206, a groove 302, a spring 303, and a clamping block 304. An installation groove 204 is opened at the top of the installation block 204. Clamping grooves 206 are symmetrically opened on the side wall of the installation groove 204. Grooves 302 are symmetrically opened on the side wall of the second pin 300. A spring 303 is fixedly arranged on the side wall of the groove 302. The end of the spring 303 is fixedly connected to a clamping block 304 adapted to the clamping groove 206. When the optocoupler body 301 needs to be replaced, the optocoupler body 301 is moved upward, and the clamping block 304 is compressed by the side wall of the installation groove 204. The spring 303 is compressed by the clamping block 304, so that the clamping block 304 is retracted into the groove 302, facilitating the pulling out of the second pin 300 from the installation block 204, thereby facilitating the rapid replacement of the optocoupler body 301. There is no need to heat the solder joints to remove the first pin 200 from the PCB board. The operation is simple, time-saving and labor-saving, reducing the impact on other components on the PCB board, improving the convenience of replacing the optocoupler body and the reliability of the optocoupler packaging pin structure, greatly reducing the packaging failure of the vehicle optocoupler. A guiding mechanism for guiding the installation of the clamping block 304 is provided on the side wall of the installation groove 204.

[0032] In one embodiment, as Figures 2 - 6 shown, the guiding mechanism includes a guiding groove 205 and a guiding block 305. Guiding grooves 205 are symmetrically opened on the side wall of the installation groove 204. Guiding blocks 305 adapted to the guiding grooves 205 are symmetrically and fixedly arranged at the bottom of the second pin 300. The second pin 300 is guided by the guiding block 305, facilitating the insertion of the second pin 300 into the installation groove 204 and improving the convenience during clamping installation.

[0033] In one embodiment, as Figure 6 shown, a chamfer is provided on the side wall of the guiding block 305. The guiding block 305 with chamfered edges is easier to insert into the guiding groove 205, thus facilitating the positioning of the guiding block 305 and improving the practicality of the structure.

[0034] In one embodiment, as Figures 1 - 2 shown, the welding mechanism includes an arc-shaped opening 202 and a through hole 203. An arc-shaped opening 202 is opened at the end of the first pin 200. By providing the arc-shaped opening 202, the soldering area can be increased, making the welding more stable. A plurality of through holes 203 are opened at the top of the first pin 200 at the position of the arc-shaped opening 202, reducing material usage and cost.

[0035] Embodiment 2

[0036] In one embodiment, as Figures 1 - 3As shown, insulating sleeves are sleeved on the side walls of the first pin 200 and the second pin 300, which play an insulating role to avoid damage to the optocoupler body 301 caused by poor contact between the first pin 200 and the second pin 300, and extend the service life.

[0037] Working principle: During use, the fixing rod 105 is snapped into the fixing groove 104, and the first housing 100 and the second housing 103 are used to encapsulate and protect the optocoupler body 301 to improve the structural stability. The guide block 305 is used to guide the second pin 300 to facilitate inserting the second pin 300 into the installation groove 204, improving the convenience during snap-in installation. When the optocoupler body 301 needs to be replaced, the optocoupler body 301 is moved upward, the clamping block 304 is compressed by the side wall of the installation groove 204, and the spring 303 is compressed by the clamping block 304, so that the clamping block 304 is retracted into the groove 302, facilitating pulling out the second pin 300 from the installation block 201, thereby facilitating the quick replacement of the optocoupler body 301. There is no need to heat the solder joints to remove the first pin 200 from the PCB board. The operation is simple, time-saving and labor-saving, reducing the impact on other components on the PCB board, improving the convenience of replacing the optocoupler body and the reliability of the optocoupler packaging pin structure, and greatly reducing the packaging failure of the vehicle-use optocoupler.
