Abstract
Description
- The present invention relates to an electrical connector, and particularly to a micro electrical connector for mating with a complementary connector.
- A normal USB receptacle connector comprises an insulative housing, a shell enclosing the insulative housing and a plurality of contacts received in the insulative housing. Each contact always comprises a tail portion for soldering to an electronic member, such as a motherboard. The tail portions are exposed out of the insulative housing and the shell. However, as the development, the electronic member becomes more and more smaller. Therefore, the interior space between the electrical connector also becomes smaller. Accordingly the effect of the Electro-Magnetic Interference (EMI) to the discovered tail portions is obvious.
- Obviously, it is desirable to have an electrical connector has an improved structure.
- An object of the present invention is to provide an electrical connector to prevent EMI to the contacts.
- To achieve the above object, an electrical connector adaptor for connecting with a complementary connector in a mating direction, comprises a shell, an insulative housing received in the shell and a plurality of contacts received in the housing. The shell comprises a top surface, a pair of lateral surfaces, respectively, connecting with the top surface, and a two-parts rear surface, respectively, bent from the lateral surfaces. The two-part rear surface comprises a base plate and a shielded plate extending rearwardly from the base plate. Each contact comprises a tail portion exposed out of the insulative housing. The shielded plate is above and covers the tail portions of the contacts.
- Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
- FIG. 1 is an assembled, perspective view of an electrical connector in accordance with the present invention;
- FIG. 2 is a view similar to FIG. 1, but taken from a different aspect;
- FIG. 3 is a perspective view of an insulative housing with the contacts assembled on of the electrical connector shown in FIG. 1; and
- FIG. 4 is a view similar to FIG. 1, but taken from a different aspect, with a contact is pulled out of the insulative housing.
- Referring to FIGS. 1 and 2, an
electrical connector 100 comprises ashell 1, an insulative housing received in theshell 1, and a plurality ofcontacts 3 insert-molded in theinsulative housing 2. - Still referring to FIGS. 1 and 2, the
shell 1 comprises atop surface 11, abottom surface 12, aleft surface 13, aright surface 14 and arear surface 15 bent rearwardly from theleft surface 13 and theright surface 14. Above-mentioned surfaces together define a receiving room (not labeled). Thetop surface 11, thebottom surface 12, the left and theright surface top surface 11 comprises aresilient tab 111 bent into the receiving room for resisting the shield (not shown) of the complementary connector. Thetop surface 11 comprises a pair ofholding portions 112 extending rearwardly from the opposite ends of a rear edge thereof. Theholding portions 112 and therear surface 15 together define a receiving space (not labeled). Theleft surface 13 and theright surface 14, respectively, forms apositioning tab 121 extending outwardly therefrom for positioning theelectrical connector 100 on the motherboard (not shown) during soldering. Thebottom surface 15 comprises a pair ofrestricting tabs 122 extending rearwardly from the opposite ends of a rear edge thereof. Therear surface 15 comprises abase plane 151 and a shieldedplane 152 extending rearwardly from thebase plane 151. - Referring to FIG. 3 and FIG. 4, the
insulative housing 2 comprises amain body 21 and amating portion 22 extending forwardly from themain body 21. Themain body 21 comprises aretaining block 212 projecting upwardly therefrom. Theretaining block 212 is located between theholding portions 112 of theshell 1 for restricts the movement in a front-to-back direction of thehousing 2. A plurality ofblocks 213 are alternatively formed at abottom wall 218 of themain body 21 engaging with thebottom surface 12 of theshell 1. A plurality ofslits 216, respectively, forms between every twoadjacent blocks 213. A pair ofstopping blocks 215 are formed at the opposite ends of the bottom wall for engaging with the restrictingtabs 122 of the shell to restrict the movement in a lateral direction of thehousing 2. A pair ofengaging blocks 214 are formed at the opposite ends of themain body 21 for engaging with the inner surface of the left andright surface shell 1. Themating portion 22 defines a plurality of receivingslots 2221 thereon. - Each
contact 3 comprises acontacting portion 34, aretaining portion 33 extending downwardly from the contacting portion and atail portion 32 extending rearwardly from theretaining portion 33. The contactingportions 34 are received incorresponding slots 2221. Theretaining portions 33 are insert-molded in thehousing 2. The tail portions are exposed out of thehousing 2 and located between theslits 216 of the housing. Furthermore, the tail portions are fixed between the restrictingtabs 122 of theshell 1 and under the shieldedplanes 152 of theshell 1. Therestricting tabs 122 prevent Electro-Magnetic Interference (EMI) to thetail portions 32 from the lateral direction. The shieldedplanes 152 prevent EMI totail portions 32 from the front-to-back direction and an up-to-down direction. - It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
