Abstract
The utility model discloses a high-definition multimedia interface comprising a PIN terminal body which is formed from plastics through injection moulding, a plastic body and a metal shell. The PIN terminal body is embedded and inserted into the plastic body and fixed. The metal shell sleeves the plastic body and in snap connected with the PIN terminal body. The high-definition multimedia interface is characterized in that a clamp hook and an inner groove are arranged in the plastic body, the clamp hook comprises a hook-like portion and an installation portion, the clamp hook is arranged in the inner groove, the installation portion and the inner groove are in matching fixation, the lower end of the PIN terminal body is provided with a notch, the lower end of the installation portion is provided with a bump, the bump is arranged on the notch for matching fixation, a matching hole is formed in the metal shell, and the hook-like portion is arranged in the matching hole. According to the obtained high-definition multimedia interface, the left side and the right side of the plastic body of the product are provided with a clamp hook structure separately, so the pullout force after a plug is plugged can be increased, the condition that the product is separated from the connector due to vibration or external force during utilization can be prevented, so that the product utilization reliability can be enhanced.
Description
Technical field
The utility model relates to a kind of interface, particularly a kind of HDMI (High Definition Multimedia Interface).
Background technology
At present, HD digital multimedia interface transmission technology does well, better performances be HDMI technology, HDMI technology is a kind of brand new digital video of high definition epoch standard, technology of these aspects of audio interface of meeting, product is widely used in Digital Television.Set Top Box.In projector lamp device product, high-resolution video and the multichannel audio data of one digital form transmission uncompressed, HDMI interface has the feature of plug and play, but the speed of HDMI transmission does not at present reach perfect effect at a high speed and interface and connector along with permanent its poor stability using, time and occur waving or disconnected news phenomenon, interface is unstable easily loosening.
Summary of the invention
The purpose of this utility model be provide in order to solve above-mentioned the deficiencies in the prior art a kind of simple in structure, with coupler construction and be difficult for loosening HDMI (High Definition Multimedia Interface).
To achieve these goals, a kind of HDMI (High Definition Multimedia Interface) that the utility model is designed, include the PIN terminal body of plastic-injection moulding, plastic body and metal shell, described PIN terminal body intercalation is fixing in plastic body, metal shell is enclosed within on plastic body and with PIN terminal body buckle and is connected, it is characterized in that: in described plastic body, be provided with snap fit and inner groovy, this snap fit comprises crook and installation portion, snap fit is placed in inner groovy, installation portion and inner groovy are fixed, described PIN terminal body lower end is provided with breach, installation portion lower end is provided with projection, this projection is arranged on breach and is fixed, on described metal shell, be processed with mating holes, crook is placed in mating holes.
Preferably, described metal shell is also provided with window, make to insert time socket shell fragment be buckled in two windows, improved the withdrawal force of product.
The HDMI (High Definition Multimedia Interface) that the utility model obtains, on the limit, plastic body left and right of product, increase coupler construction, increase plug to the withdrawal force after inserting, prevented that product from coming off with connector due to vibrations or while being subject to external force in use, thereby strengthened the reliability of product use.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figure 1 to 11, a kind of HDMI (High Definition Multimedia Interface) that the utility model provides, include the PIN terminal body 1 of plastic-injection moulding, plastic body 2 and metal shell 3, described PIN terminal body 1 intercalation is interior fixing at plastic body 2, metal shell 3 is enclosed within on plastic body 2 and with PIN terminal body 1 buckle and is connected, buckle connected mode refers to and on metal shell 3, is provided with catching groove 31, in PIN terminal body 1, be processed with projection 10, projection 10 is buckled on catching groove 31, as Fig. 2, the terminal body of PIN shown in Fig. 31 comprises pressure side and presses down terminal, on, the number that presses down terminal can be as required fixed, what the design mainly adopted is that the upper pressure side son 11 of 9PIN and 10PIN press down terminal 12, in described plastic body 2, be provided with snap fit 4 and inner groovy 5, this snap fit 4 comprises crook 42 and installation portion 41, snap fit 4 is placed in inner groovy 5, installation portion 41 is fixed with inner groovy 5, described PIN terminal body 1 lower end is provided with breach 13, installation portion 41 lower ends are provided with projection 43, this projection 43 is arranged on breach 13 and is fixed, on described metal shell 3, be processed with mating holes 33, crook 42 is placed in mating holes 33.
Above-mentioned to a kind of HDMI (High Definition Multimedia Interface) further instruction obtaining: described metal shell is also provided with window 32, make to insert time be buckled in two windows by the shell fragment of socket, improve the withdrawal force of product, on the installation portion of snap fit partial shape and with the inner groovy fit structure of plastic body, the shape of snap fit can accomplish to insert swimmingly in limited space in metal shell and plastic body assembly, and by and plastic body location hole between interference engagement realize fixing, as shown in figure 10, crook 42 is in the inner groovy front end location of plastic body, fixing, under support, can under external force extruding, snap fit previous section produce deformation, thereby realize the function of snap fit, on the limit, plastic body left and right of product, increase coupler construction, increase plug to the withdrawal force after inserting, prevented product in use due to vibrations or while being subject to external force and female seat come off, thereby strengthen the reliability that product uses.
Be pointed out that, snap fit is stressed while being down out of shape, snap fit entirety can be subject to a counterclockwise moment loading, and the support that presses down terminal 12 formed bodys by 10PIN can this moment of balance, thereby prevented that snap fit is subject to occur that lower notch distortion is bad after external force.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; its framework form can be flexible and changeable; just make some simple deduction or replace, all should be considered as belonging to the utility model by the definite scope of patent protection of submitted to claims.
