MPO/APC-24 grinding fixture

MPOIntroduction to Grinding Fixtures

1. The name of the invention

High handle MPO grinding fixture

Technical field

The inventor belongs to the field of optical fiber communication equipment

Existing technology

Compared with the present invention, the most recent similar technologies include the "Demai" grinding fixture from the United States, which is a center pressurized MPO/PC-12 fixture with good performance but expensive price, and must be matched with the "Demai" grinding machine from the United States. The market price of a Demai grinding machine is over 20000 US dollars, equivalent to about 140000 RMB, and the market price of an MPO/PC-12 Demai fixture is over 5000 US dollars, equivalent to more than 30000 RMB. The total cost of the two fixtures is around 170000 RMB. The equipment is good, but the price is not cheap, which puts great pressure on customers in terms of cost.

Purpose of Invention

Due to the high price of MPO/PC-12 Demai grinding fixture, I conducted serious research and carried out technological innovation on this basis to develop MPO grinding fixture. This fixture has MPO/PC-16, MPO/APC-16, MPO/PC-24, MPO/APC-24, and its market price is around RMB 20000. Compared with the Demai MPO/PC-12, the price is about 50% lower, and one fixture can accommodate 24 cores. Whatever product is needed, the fixture can be installed. More importantly, the MPO universal four corner grinding fixture can be matched with any existing four corner grinding machine for grinding, so there is no need to buy a Demai grinding machine because this fixture is designed based on the improvement of Demai fixtures and will not tilt or sway. In this way, one machine and one fixture can save users more than 150000 yuan in costs. Its technical quality is equivalent to or even better than that of Demai fixtures, and it is more stable. Better and more stable performance is reflected in the product's one-time 3D pass rate of 100%. The price has decreased and efficiency has improved, and the real beneficiaries are the customers.

Invention content

The MPO grinding fixture is developed through technological innovation based on the MPO-12 Demai grinding fixture. The fixture consists of the following parts: ① fixture base plate ② pressure block seat ③ pressure block ④ top wire ⑤ locking screw ⑥ product slot ⑦ wire holder, etc

Its technical features are as follows: ① The structure is simple, with the pressing block seat, pressing block, and top wire acting as a whole, and both the pressing block and top wire are fixed on the pressing block seat. ② The operation is simple, gently insert the MPO plug into the product slot, twist the top wire with a small hexagonal screwdriver, and push the pressing block downwards at a 48 degree angle. At this time, the small hook on the pressing block moves towards the top of the MPO product. Since the top wire and pressing block have a pivot point and a 48 degree angle, the transverse surface of the pressing block also presses up on the product at the same time, so that the product is firmly and evenly controlled in the product slot when pressed up and horizontally. ③ It is easy to use and... Twist the small hexagonal screwdriver down to press down on the product, and then twist it back to exit the product. ④ Installing a fixed cable rack on top of the base plate has the advantage of clamping a single fiber optic cable while installing the product. This ensures that the fiber core will not break, which not only improves the qualification rate but also enhances efficiency.

The Effect of Invention

The invention of MPO grinding fixture is a technological revolution, and its price can save more than 150000 yuan in costs calculated based on a single machine and fixture. Not only does it greatly reduce costs, but its technical quality is equivalent to or even better than MPO/PC-12 Demai grinding fixture, and more stable.

MPO grinding fixture, verified through actual grinding. The fiber end face and 3D (curvature radius, vertex offset, fiber height) pass rate both reach 100%

Abstract of the present invention: The present invention is a technological innovation that optimizes the design and assembly of fixtures, with simple structure, convenient use, excellent effect, greatly reducing costs, improving work efficiency, and achieving the best grinding effect.
