Description

Technical Field:

[0001] The utility model relates to the field of production and manufacturing of communication equipment, and particularly relates to a high-density heating protection cap. Background Art:

[0002] An optical fiber connector permanently or separably connects two optical fibers together and has a connection part with a protection component. The optical fiber connector is an end device of the optical fiber.

[0003] In order to avoid contamination at the joint, a protection cap is installed at the joint. In the production of the protection cap, when producing an optical fiber connector, the glue in the optical connector needs to be heated and cured, so a curing machine is required. Conventional heating protection caps for optical fiber connectors are too large in volume to be used at high density, resulting in low curing efficiency. At the same time, the heating and cooling speeds are relatively slow, affecting the usage frequency.

[0004] Therefore, a protection cap that can be used at high density and is convenient for heat dissipation is needed. Content of the Utility Model:

[0005] The purpose of the utility model is to provide a high-density heating protection cap.

[0006] The utility model is implemented by the following technical solutions:

[0007] A high-density heating protection cap includes a joint and a protection cap. There are two jacks and two heat dissipation grooves in the protection cap. A push-pull rod is arranged in each heat dissipation groove. A piston block is slidably connected in each heat dissipation groove. A wind inlet hole is fixedly arranged at the center of the inner side wall of each piston block. A first one-way valve is fixedly installed in the wind inlet hole. A plurality of air outlet holes are annularly and evenly arranged on the side wall of the piston block. A second one-way valve is fixedly installed in each air outlet hole.

[0008] Preferably, the cross-sectional area of the wind inlet hole is the same as the total cross-sectional area of the corresponding plurality of air outlet holes, and the heat dissipation groove is axially opposite to the corresponding jack.

[0009] Advantages of the utility model: The protection cap is provided with a double-hole shape, which reduces the distance between two adjacent joints, so that more joints can enter the curing furnace in the same batch, thereby increasing the working efficiency. Pull the push-pull rod back and forth, so that the wind quickly enters and exits the heat dissipation groove, thereby accelerating the heat dissipation efficiency, making the usage efficiency higher and the heat dissipation faster. Description of the Drawings:

[0010] Figure 1 is the first perspective three-dimensional view of the structure of the utility model;

[0011] Figure 2 is the second perspective three-dimensional view of the structure of the utility model;

[0012] Figure 3 It is the structural diagram of the protective cap in the structure of the present utility model.

[0013] In the figure: joint 1, protective cap 2, push-pull rod 3, jack 4, heat dissipation groove 5, piston block 6, air inlet hole 7, air outlet hole 8, first one-way valve 9, second one-way valve 10. Specific implementation manner:

[0014] As Figures 1 to 3 shown, a high-density heating protective cap includes a joint 1 and a protective cap 2. There are two jacks 4 and two heat dissipation grooves 5 arranged in the protective cap 2. A push-pull rod 3 is arranged in each heat dissipation groove 5. A piston block 6 is slidably connected in each heat dissipation groove 5. An air inlet hole 7 is fixedly arranged at the center of the inner side wall of each piston block 6. A first one-way valve 9 is fixedly installed in the air inlet hole 7. A plurality of air outlet holes 8 are annularly and evenly arranged on the side wall of the piston block 6. A second one-way valve 10 is fixedly installed in each air outlet hole 8. When working, directly insert the end of the joint 1 into the corresponding jack 4 to protect the end of the optical fiber from being contaminated. At the same time, the protective cap 2 is arranged in a double-hole shape, so as to reduce the distance between two adjacent joints 1, enabling more joints 1 to enter the curing furnace in the same batch, thereby increasing the working efficiency. Further, a piston block 6 is arranged in each heat dissipation groove 5. After curing, pull the push-pull rod 3 back and forth to make the wind quickly enter and exit the heat dissipation groove 5, thereby accelerating the heat dissipation efficiency, making the use efficiency higher and the heat dissipation faster. When pushing the push-pull rod 3 inward, the hot air inside the wind is discharged along the plurality of air outlet holes 8. When pulling the push-pull rod 3 outward, the wind enters along the air inlet hole 7. When entering the air, the aperture is large and the air can enter quickly. When discharging the air, the aperture is small but the number is large. When maintaining the same blowing efficiency, due to the small aperture, the air outlet speed is faster, which can accelerate the flow of the air current and ensure the heat dissipation efficiency.

[0015] The cross-sectional area of the air inlet hole 7 is the same as the total cross-sectional area of the corresponding plurality of air outlet holes 8, and the heat dissipation groove 5 and the corresponding jack 4 are axially opposite, so as to ensure that the air inlet volume is the same as the air outlet volume and ensure the heat dissipation efficiency.

[0016] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
