[Technical field to which the new type belongs] ^ This creation is a housing of a connection base, especially a housing with a groove structure design 'to increase the elasticity of the elastic sheet body. [Previous technology] The USB (Universal Serial Bus) connector is a connector widely used in computers, computer peripherals and various digital electronic products. Because f has the advantages of hot plugging and high-speed transmission, it is very common and demanded. The amount is quite large, so the relevant manufacturers must start from the structural or process design and other aspects to improve the reliability of the use of USB connectors, and try to reduce the cost. -In order to meet the trend of miniaturization of various digital electronic products, mini-USB connectors have been developed accordingly, and their size is only about one-eighth of traditional USB connectors, so it is quite suitable for portable electronic devices. The Mini US] connector includes a USB socket and a corresponding USB plug. The structure of the USB socket ^ is shown in the first figure. As can be seen from the figure, the USB socket 10 includes a terminal base 12 provided with a plurality of terminals. And a shell 14 covering the outside. The top surface of the shell 14 is provided with two grooves 16 of approximately v-shape, inverted v-shape and v-shape. Each groove 16 sandwiches a part of the shell. 14 to form an elastic sheet body, which includes grounding elastic pieces 18 formed on both sides and a snapping elastic piece ig formed in the center. The suspended end of each elastic piece body has a recess 20, and the recesses of the ground elastic pieces M on both sides 20 can contact the USB plug to provide grounding, and the central clip spring 19 is used to snap into the USB slot of the USB plug; in addition, referring to the second and third figures, the casing 1 4 bis is opened on the side There are two sliding grooves 22, which are used to accommodate the terminal portions 12 and the engaging portions 2 4 provided on the two sides; further, referring to the first figure, the housing

The U-shaped groove 28 can form a shell between them. A clip 30 has the function of assisting the fixed terminal base 12. However, the structure of the above-mentioned USB socket 10 is missing as follows. First, since the size of the mini USB connector is quite small, the size of the corresponding USB socket 10 is naturally small, so the top surface of the housing 14 can be used. The area where the grooves 6 are formed to form the clip spring 19 is not large, and the two adjacent grooves 16 need to be spaced apart to prevent the width of the shell 16 from being too narrow and the strength too low. Therefore, it is limited. Due to the space between the size of the housing 14 and the groove 16, and considering the difficulty and yield of manufacturing, the size of the groove 16 cannot be further increased to sandwich the formation area, which is larger, more resilient and more concentrated. The spring clip 19 is connected, so the number of times that the USB socket 10 can be used is relatively limited by the reliability of the spring clip 19. Second, the opening of the sliding grooves 22 on the two sides of the casing 14 will reduce the strength of the casing 14, Similarly, the reliability of the USB socket 10 will be further reduced. Third, the card 30 has a small area and insufficient strength, so the effect of auxiliary fixing is limited, and it cannot really have the effect of = H solid terminal block 12; its W, There are too many openings on the top surface of the housing 1 and the U-shaped groove 28 is too large. The housing 14 of the electromagnetic shielding property is poor, it is difficult to avoid the influence USB receptacle 1〇 by the noise. 2 Here, in response to the difficulties of the above-mentioned know-how, the author proposes a housing of a connecting seat to effectively overcome the lack of knowledge. [New content] The main purpose of using ί 2I is to provide a housing of a connection seat, which is made up of > I ^ 冓, to increase the strength of the shape sandwiched by the groove, thereby providing the use of this creation The USB socket is stable M250389 IV.
