The present invention relates to an electrical connector comprising an insulative housing, a center conductor secured to the insulative housing, and a metallic shell secured to the insulative housing and surrounding the center conductor, wherein the metallic shell includes a sleeve having a lower part secured to the insulative housing and an upper part provided with features for reliably retaining to a corresponding shell of a complementary electrical connector. This application relates to the copending application with the same inventor and the same filing date and a title of METALLIC OUTER SHELL OF AN ELECTRICAL CONNECTOR HAVING CURVILINEAR FLAPS AND INTERPOSED SPRINGY FLAPS.
Taiwan Patent No. 388157 discloses an electrical connector comprising an insulative housing, a center conductor (2) secured to the insulative housing, and a metallic shell secured to the insulative housing and surrounding the center conductor, wherein an upper part of the metallic shell includes a plurality of spring flaps and the metallic shell is so formed as to have a seam. China Patent No. 204045745 discloses a multi-lobe contact elastic arm terminal that is formed by a drawing operation to have low height and small dimension while achieving multi-point elastic contact during mating with a complementary pin terminal.
An electrical connector comprises: an insulative housing having a base; a center conductor secured to the insulative housing; and a metallic shell secured to the insulative housing and surrounding the center conductor, the metallic shell including a sleeve having a lower part secured to the base of the insulative housing and an upper part extending upwardly beyond the base of the insulative housing; wherein the insulative housing is insert-molded with the center conductor and the metallic shell; and the sleeve of the metallic shell is formed as a seamless structure.
Referring to
The insulative housing 1 includes a base 11. The base 11 has a top end face 110 and a bottom end face 111. The center conductor 2 has a main portion 21, a contact portion 22 extending upward from the main portion 21 beyond the top end face 110 of the base 11, and a soldering portion 23 extending horizontally outwardly from the main portion 21. The metallic shell 3 includes a sleeve 31 surrounding the center conductor 2 and a plurality of soldering legs 32. The soldering legs 32 include a pair of first legs 321 and a second leg 322.
The sleeve 31 of the metallic shell 3 is formed as a seamless structure by a metal drawing process to have an increased structural strength. The sleeve 31 of the metallic shell 3 may alternatively be formed metallurgically to have a seamless body. The sleeve 31 has a lower part 311 secured to the base 11 of the insulative housing 1 and an upper part 312 extending upwardly beyond the top end face 110 of the base 11. The seamless upper part 312 is sufficiently rigid to not easily deform during mating with a complementary electrical connector.
The upper part 312 has an outer wall face 3120 and an inner wall face 3121. A plurality of inward bulges 3122 are formed, e.g., by stamping prior to the metal drawing process, on the inner wall face 3121 of the upper part 312, leaving corresponding depressions 3123 on the outer wall face 3120 thereof. The bulges 3122 will retain to a corresponding shell of the complementary electrical connector. The base 11 has slots 112 extending through the top and bottom end faces 110 and 111 and aligned with the inward bulges 3122. The upper part 312 has a chamfer 3124 at an upper inner edge thereof immediately adjacent to the bulges 3122 so as to have a feel of smooth transition from the chamfer 3124 to the inward bulges 3122 during mating with a complementary electrical connector.
The insulative housing 1 has a post 12 extending upward from the base 11. The post 12 has a hole 121 through its top surface 120 and the contact portion 22 of the center conductor 2 is positioned in the hole 121. The upper part 312 surrounds the post 12 to define a groove 313. The contact portion 22 has a pair of arms 221 enclosed by the post 12. The main portion 21 has a planar portion 211 and two opposite first and second vertical portions 212 and 213. The pair of arms 221 extend from the other two opposite sides of the planar portion 211. The vertical portions 212 and 213 are embedded in the base 11 and the soldering portion 23 exposes outside the bottom end face 111 of the base 11. The portion 23 has a pair of notches 231 for reliable bonding with the base 11.
