Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical socket technology, and in particular to a testing fixture for the insertion and extraction force of optical socket products. Background Technology
[0002] Among the performance indicators of optical socket products, insertion and extraction force is one of the important indicators.
[0003] There are currently two methods for testing insertion and extraction force on the market: one is to use a single weight for measurement, and the other is to use a digital push-pull force gauge for measurement.
[0004] The first single-weight test method uses the weight of the weight as the standard of measurement. The test procedure is to first place the weight flat on the table, then insert the optical socket into the socket of the weight, and then lift the product vertically. If the weight is lifted along with the product, it means that the insertion and extraction force of the product is greater than the weight of the weight; conversely, if the weight cannot be lifted and falls off the product, it means that the insertion and extraction force of the product is less than the weight of the weight. The disadvantage of this method is that it only has a single standard of measurement, while optical sockets usually have two standards for insertion and extraction force: an upper limit and a lower limit. This requires two sets of weights, one for the upper limit and one for the lower limit, resulting in two tests and reduced overall efficiency.
[0005] Therefore, a testing fixture for the insertion and extraction force of optical socket products is still needed to solve the above problems. Utility Model Content
[0006] This utility model provides a testing fixture for the insertion and extraction force of optical socket products to solve the above-mentioned problems.
[0007] The objective of this utility model is achieved through the following technical solution:
[0008] A fixture for testing the insertion and extraction force of an optical socket product includes:
[0009] A ferrule, the top of which has a tip that mates with the light socket to be tested;
[0010] The first standard part has a insertion groove formed on its top, which is used to insert the bottom end of the ferrule. The top of the first standard part has a threaded portion near the periphery of the insertion groove, which is connected to an expansion portion. The expansion portion is used to hold the ferrule tightly in the insertion groove.
[0011] At least one second standard component is coupled to the bottom of the first standard component. A first insertion and extraction force can be tested when the first standard component and the ferrule are lifted, and a second insertion and extraction force can be tested when the first standard component, the ferrule, and the second standard component are lifted.
[0012] In one embodiment, the second standard part is provided with a connecting groove that extends through the top and bottom, the connecting groove contains the end of a coupling member, and the shaft of the coupling member extends out of the connecting groove and connects to the bottom of the first standard part.
[0013] In one embodiment, a stepped portion is formed near the top of the connecting groove near the second standard part, the stepped portion being used to prevent the coupling member from being pulled out of the connecting groove, and the protruding portion of the coupling member is threadedly connected to the bottom threaded hole of the first standard part.
[0014] In one embodiment, an expansion sleeve is formed on the first standard part around the top of the insertion slot, and the expansion portion is threaded to the expansion sleeve to fix the insert.
[0015] In one embodiment, there are multiple second standard components, which are sequentially coupled together.
[0016] Compared with the prior art, the beneficial effects of this utility model include at least the following:
[0017] By setting up a tiered testing system for the insertion and extraction force of the ferrule, when testing the lower limit force, the top of the ferrule is inserted into the socket of the optical receptacle. Then, the first standard component directly connected to the bottom of the ferrule is slowly raised. Under the influence of gravity, the weight of the first standard component serves as the first insertion and extraction force for testing the ferrule and the optical receptacle. If the first standard component does not fall off within the gravity bearing range, the height of the ferrule can be further increased, allowing the second standard component to contribute gravity together with the first standard component, serving as the second insertion and extraction force for testing the optical insertion and extraction force. This simplified testing procedure eliminates the need for complex combinations to measure the upper and lower limits of the optical insertion and extraction force, improving work efficiency.

[0020] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.
[0021] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.
[0022] Reference Figure 1 This utility model provides a testing fixture for the insertion and extraction force of optical socket products, comprising:
[0023] The insert 5 has a top end that mates with the optical socket to be tested; the inner diameter of the insert 5 matches the inner diameter of the optical socket. When inserted, the top of the insert 5 is cylindrical, and the inner diameter of the optical socket is cylindrical. When inserted or removed, the insert 5 is inserted into the internal socket of the optical socket.
[0024] The first standard part 1 has a insertion groove formed on its top, which is used to insert the bottom end of the plug 5. A threaded portion 61 is formed on the top of the first standard part 1 near the periphery of the insertion groove, and an expansion portion 6 is connected through the threaded portion 61. The expansion portion 6 is used to hold the plug 5 tightly in the insertion groove.
[0025] At least one second standard component 3 is coupled to the bottom of the first standard component 1. When the first standard component 1 and the ferrule 5 are lifted, the first insertion / extraction force can be tested; when the first standard component 1, the ferrule 5, and the second standard component 3 are lifted, the second insertion / extraction force can be tested. The materials of the first standard component 1 and the second standard component 3 include, but are not limited to, stainless steel, brass, and aluminum alloy. The ferrule 5 is made of, but is not limited to, ceramic. The first standard component 1, as the first component to be lifted, allows for the calculation of the first insertion / extraction force by lifting the optical socket. If the ferrule 5 of the first standard component 1 does not separate from the optical socket after being fully lifted, the second standard component 3 can be lifted further. When both the second standard component 3 and the first standard component 1 are lifted, and after a period of rest following lifting, the ferrule 5 and the optical socket do not show any tendency to detach, then the upper and lower limits of the insertion / extraction force of the ferrule 5 and the optical socket meet the requirements. This eliminates the need for frequent replacement of different weights or gravity blocks and repeated operations to calculate the insertion / extraction force of the optical socket. It simplifies the testing steps for the upper or lower limits of the insertion / extraction force of the ferrule 5.
[0026] Preferably, the second standard component 3 is provided with a connecting groove 31 that extends through the top and bottom. The connecting groove 31 contains the end 21 of the coupling component 2. The shaft 22 of the coupling component 2 extends out of the connecting groove 31 and connects to the bottom of the first standard component 1. When the second standard component 3 can be flexibly connected to the gravity block at the bottom of the first standard component 1, both the first standard component 1 and the second standard component 3 provide gravity for the insertion and extraction force. The coupling component 2 can be a flexible, low-mass wire or a low-mass rigid body as mentioned in this embodiment. The diameter of the end 21 of the coupling component 2 is larger than the diameter of the shaft 22. During operation, the first standard component 1 will be pulled up first. The first standard component 1 can test the first insertion and extraction force, that is, the lower limit of the insertion and extraction force. The coupling of the coupling component 2 can also prevent the second standard component 3 from separating from the first standard component 1, making it convenient to quickly measure and calculate the first insertion and extraction force and the second insertion and extraction force through a single complete structure.
[0027] Preferably, a stepped portion 32 is formed near the top of the second standard part 3 in the connecting groove 31. The stepped portion 32 is used to prevent the coupling member 2 from being pulled out of the connecting groove 31. The protruding portion of the coupling member 2 is threadedly connected to the bottom threaded hole of the first standard part 1. The stepped portion 32 can prevent the coupling member 2 from being pulled out of the connecting groove 31. The stepped portion 32 is a stepped surface that extends inward, which can prevent the first standard part 1 and the second standard part 3 from separating from each other during use.
[0028] Preferably, an expansion sleeve 4 is formed around the top of the insertion slot on the first standard part 1, and the expansion part 6 is threadedly connected to the expansion sleeve 4 to fix the insert 5. The expansion sleeve 4 can hold or release the insert 5 under the clamping of the expansion part 6, so that different inserts 5 can be replaced according to different products in the same batch, which is convenient and quick.
[0029] Preferably, there are multiple second standard parts 3, which are sequentially coupled together. Depending on the different insertion / extraction force testing requirements, multiple second standard parts 3 can be sequentially added below the first standard part 1 to improve the convenience of multi-level insertion / extraction force testing.
[0030] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
