Description

A FI-X female digital interface

Technical field:

The utility model relates to the technical field of digital interfaces, in particular to an FI-X female digital interface.

Background technique:

Generally, the female digital interface of FI-X soft flat cable includes rubber core, terminal and iron shell, etc. At present, this kind of digital interface has the following disadvantages: 1. When the user inserts the male and female connectors from different angles, the female connector The front terminal is in contact with the male connector. Because the terminal in the female connector has no rubber core protection, the terminal is easily deformed or damaged when the male connector and the female connector of this digital interface are plugged together. 2. The position and distribution of the tight metal shrapnel inside the female head are not ideal. Therefore, when the male head and the female head are plugged together, it is easy to cause poor contact between the terminals in the male head and the female head. 3. The structure of the housing that fixes the entire female base is not strong, and the user may easily cause deformation of the housing during use.

Utility model content:

The purpose of this utility model is to provide a FI-X female digital interface for the deficiencies in the prior art. Problems with bad and poor structural strength.

In order to achieve the above purpose, the utility model is achieved through the following technical solutions: it includes a terminal, a rubber core, and an iron shell. The front end of the rubber core is provided with a female groove for the male head of the digital interface to be inserted into. There are several small slots for accommodating terminals. Terminals are inserted into each small slot of the rubber core. The rubber core is inserted into the iron shell. The front end of each small slot of the rubber core is formed with a "mouth"-shaped cavity. The front end of the terminal is an elastic curved contact part arched upwards, and the front end of the terminal is movably inserted into the "mouth" shaped cavity of the rubber core.

The front end of the iron shell is formed with a plurality of clamping shrapnels bent toward the inside, and the tightening shrapnels are located on the terminal-free side of the rubber core groove.

The clamping elastic pieces and the terminals are evenly distributed in a ratio of 1:3.

The utility model is provided with a strong iron shell on the rubber core, and the rubber core and the iron shell are fixed together, so that the rubber core is not easily deformed under different impact forces; the front end of the small groove for placing the terminal in the rubber core is formed with a "mouth" The front end of the terminal is an elastic curved contact part arched upwards. The front end of the terminal is movably inserted into the "mouth" shaped cavity of the rubber core. When the male pair is inserted into the female head, the terminal on the male head has a A certain force withstands the terminal in the female head, and can rely on its own elasticity to eliminate stress and avoid poor contact. When the user inserts with different strengths and angles, the front part of the terminal can properly extend into the space at the front end of the rubber core. cavity, so as to avoid the rubber core and the terminal in the female head from being damaged or deformed; the distribution of the clamping shrapnel and the terminal is in a ratio of 1:3, so that the female head can save the material and reduce the difficulty of production at the same time, while ensuring the male head It is relatively fixed with the female head, and the contact between the terminals on the two is guaranteed to be stable. To sum up, the utility model has a simple structure, the inner terminal of the female head is not easy to be deformed or damaged, the structural strength is high, the terminal contact is stable when the digital interface is mated, and the product electrical defect rate is low.

Accompanying drawing 3 is the exploded schematic view of the utility model.

Detailed ways:

See accompanying drawings 1, 2, and 3 for the embodiment. The female digital interface includes a terminal 1, a rubber core 2, and an iron shell 3. The front end of the rubber core 2 is provided with a female groove 4 for the male head of the digital interface to be inserted into. The core 2 is also formed with a plurality of small slots 5 for accommodating the terminals 1. The terminals 1 are inserted into each small slot 5 of the rubber core 2. The rubber core 2 is inserted into the iron shell 3. The rubber core of the female head 2. The outside is fixed by a strong iron shell 3, which fully protects the rubber core 2 and makes the rubber core 2 not easy to deform. At the same time, the rubber core 2 and the iron shell 3 are fixed together so that it is not easy to deform under different impact forces.

The front end of each small groove 5 of the rubber core 2 is formed with a "mouth"-shaped cavity 6, and the front end of the terminal 1 is an elastic curved contact part 7 that arches upward. The front end of the terminal 1 is movably inserted into the rubber core 2. In the "mouth" shaped cavity 6. Since the terminal 1 itself has a certain degree of elasticity, when the male pair is inserted into the female head, the terminal on the male head can have a certain force to withstand the terminal 1 in the female head. At this time, the terminal 1 in the female head relies on its own elasticity. Eliminate this stress and avoid poor contact. In addition, considering that when the male and female connectors of the digital interface are plugged together, when the user inserts them with different strengths and angles, the terminal 1 and the rubber core 2 in the female connector will be damaged to varying degrees, and they will be formed in front of the rubber core 2. The main purpose of the "mouth"-shaped cavity 6 is to protect the front part of the terminal 1 in the female head from being damaged or deformed. After the terminal 1 in the female head is squeezed by the male terminal of the digital interface, its The front part can properly extend into the cavity 6 at the front end of the rubber core 2, so as to prevent the rubber core 2 and the terminal 1 in the female connector from being damaged or deformed.

The front end of the iron shell 3 is formed with a plurality of clamping shrapnels 8 bent inwards. After the iron shell 3 and the rubber core 2 are assembled, the tightening shrapnels 8 on the iron shell 3 are located in the female groove 4 of the rubber core 2 On the side without the terminal 1, and the pressing elastic piece 8 and the terminal 1 are evenly distributed in a ratio of 1:3. When the male head and the female head of the digital interface are plugged in, the clamping shrapnel 8 is pressed against the male head of the digital interface, so that the male head and the female head are relatively fixed, and at the same time, the terminals on the male head of the digital interface are connected to the female head of the digital interface. The terminal 1 inside is in close contact and the contact is stable; the ratio of the clamping shrapnel 8 to the terminal 1 is 1:3, so that the female head can save the material and reduce the difficulty of production at the same time, and ensure the relative relationship between the male head and the female head. fixed, and ensure that the contact of terminal 1 on both is stable.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
