[0031] Example 1

[0032] like Figures 1-6 As shown, an integrated dispensing fixture for high-speed DAC cables in an OSFP includes:

[0033] The base 1 and the top cover 2 are provided. The top cover 2 covers the base 1. A receiving cavity 3 is formed between the base 1 and the top cover 2. The outline shape of the receiving cavity 3 matches the outline shape of the DAC high-speed cable 7. The receiving cavity 3 runs through the front and rear sides of the top cover 2 and also through the front and rear sides of the base 1. The receiving cavity 3 is used to accommodate the DAC high-speed cable 7. The receiving cavity 3 consists of two parts, one part is located on the top cover 2 and the other part is located on the base 1. When the top cover 2 covers the base 1, a complete receiving cavity 3 is formed.

[0034] A gasket 6 is horizontally arranged in the front entrance of the receiving cavity 3. Since the single cable in the DAC high-speed cable 7 is distributed in a stacked manner, there are four layers, with the top two layers tightly attached together and the bottom two layers tightly attached together. There is a 0.5mm gap between the single cable in the top two layers and the single cable in the bottom two layers. Therefore, the gasket 6 is inserted into the single cable distributed in a stacked manner to separate the single cable in the top two layers and the single cable in the bottom two layers, thereby achieving sealing. This prevents the glue from flowing to other places where there should be glue when the glue is poured into the first molding cavity 4 later.

[0035] The receiving cavity 3 is provided with a first forming cavity 4 that forms an adhesive block 8 on the cable when the adhesive is poured in, so as to wrap the cable circumferentially and divert and limit the flow of individual cables. Specifically, it can be understood as follows:

[0036] The base 1 has a first molding cavity 4 located near the gasket 6 in the receiving cavity 3. When the glue is poured into the first molding cavity 4, a glue block 8 will be formed in the first molding cavity 4 to wrap around all the single cables and to divert and limit the single cables.

[0037] The second forming cavity 5 is arranged in the accommodating cavity 3 of the base 1 and close to the tail sleeve of the DAC high-speed cable 7, and when the glue is poured into the second forming cavity 5, a limiting glue block 9 will be formed in the second forming cavity 5 to wrap all the single cables in the circumferential direction and prevent the cables from moving forward and backward and rotating in the structure.

[0038] The second forming cavity 5 is arranged in the accommodating cavity 3 of the base 1 and close to the tail sleeve of the DAC high-speed cable 7, and when the glue is poured into the second forming cavity 5, a limiting glue block 9 will be formed in the second forming cavity 5 to wrap all the single cables in the circumferential direction and prevent the cables from moving forward and backward and rotating in the structure.

[0039] Two glue inlet holes 210 are arranged on the upper cover 2 and communicate with the first forming cavity 4 and the second forming cavity 5 respectively, that is, the glue can be poured into the first forming cavity 4 through the glue inlet hole 210 communicating with the first forming cavity 4, and the glue can be poured into the second forming cavity 5 through the glue inlet hole 210 communicating with the second forming cavity 5, and the glue inlet hole 210 is preferably inverted conical.

[0040] In this scheme, the first forming cavity 4 and the second forming cavity 5 are both composed of two parts, one part is located on the upper cover 2 and the other part is located on the base 1, and when the upper cover 2 is covered on the base 1, a complete first forming cavity 4 and a complete second forming cavity 5 are formed.

[0041] When the tool is applied to dispensing glue on the DAC high-speed cable 7 which is assembled by the cables, the DAC high-speed cable 7 is placed on the base 1, then the gasket 6 is inserted into the corresponding position, and then the upper cover 2 is covered, so that the DAC high-speed cable 7 is in the accommodating cavity 3.

[0042] According to the pressure of the dispensing machine, the liquid glue is injected into the first forming cavity 4 and the second forming cavity 5 through the two glue inlet holes 210 respectively, and after cooling, a glue block 8 is formed on the cable to wrap all the single cables in the circumferential direction and separate the single cables and limit the single cables, and a limiting glue block 9 is formed on the cable to wrap all the single cables in the circumferential direction and prevent the cables from moving forward and backward and rotating in the structure.
