Abstract

An electrical connector for mounting on a printed circuit board includes an insulative housing and a number of terminals received in the housing. Said housing defines a pair of positioning posts extending into the printed circuit board on the bottom thereof. The first positioning post defines a number of ribs for engaging in the printed circuit board. The second positioning post defines no ribs in a direction perpendicular to a hypothetical line connecting the first and second posts.

Description

1277261 ^-- , , V. DESCRIPTION OF THE INVENTION (1) Technical Field The present invention relates to an electrical connector, and more particularly to an electrical connector mounted on a circuit board. [Prior Art] As shown in the first figure and the first figure, two methods are known in the art to mount the electrical connection state on the circuit board. One of the methods is to provide a positioning post 17 at the bottom of the edge of the body 10, and a mounting hole is provided on the circuit board 4, and the clamping post 17 is inserted into the mounting hole 40 to be electrically connected.丨, fixed. For the electrical connector that needs to be used repeatedly and repeatedly inserted, ", with the circuit board 4, the mounting hole 4〇,, = grabbing force, can be placed on each _ positioning post 1?, The production of the essence should be t==the more closely the pupil is, the stronger the stress is, and the damage is realized during the period. However, the manufacturing precision is too high: it is possible that the components are installed in the circuit board. Each tolerance is difficult to achieve. ~ 疋 while heating, low fit Red on the above, it is necessary to provide one. Electrical connector with improved structure [Summary of the Invention] The purpose of the invention is to provide an electrical connection 5 „ 达 = = = = = = = 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔 岔a plurality of guides on the body of the circuit board and the valleys in the insulating body

The bottom portion is provided with a first and a second person m 2 extending downwardly into the circuit board, respectively, and is respectively protruded to the horizontal periphery to be interfitted with the circuit board: a solid portion: a rib portion along which the second positioning post and the first positioning post are: 2

A rib that does not protrude and interferes with the board. Q, the Ming electrical connector can be further connected to the second positioning column, the line too & the sergeant said mad / oral one and the first involved. ^ ^ Two ribs are arranged in the straight direction to compare with the board dry technology, the electrical connector of the present invention has the following effects: - the board is positioned without the shifter - the second positioning post with the holding ribs in the straight direction Further positioning is not provided with the holding ribs in the vertical direction and does not need to interfere with the circuit board, and is tightly and firmly mounted to the "parent two" under the tolerance condition. Please refer to the third to sixth figures, the present invention The electrically insulating body 10, the plurality of conductive terminals 20, and the shielding case 3. The insulating body 10 includes a base U, a front extending plate 12 from the base u, and a front extending from the base 11 to be opposite to the tongue 12. The tongue number receiving passage 14 extends through the base portion n ^ in the mating direction. The rear end of the complex base portion π is further provided with a portion extending through the bottom portion of the base portion n and a plurality of notches 16. The bottom surface of the mounting portion 13 is provided to extend into the circuit board 4 The first and second positioning posts 17, 18 of the slot 15 and the second and second positioning posts 17, 18, wherein the first positioning post/eight mountings are provided with four holding ribs W7〇 to the W, rear, left and right convex, and the second positioning knife is Don't lick 6 pages 1272721

1 8 is convexly disposed along a direction perpendicular to a direction in which the first positioning post 丨 7 is connected

Jltz 1 Q λ Η/] Η 8 ϋ ° The sides of the bottom surface of the mounting portion 1 3 are also convexly provided with a strong leg portion 19 against the circuit board 4. The conductive terminal 20 is a right angle type and is housed in the corresponding terminal receiving passage 14 in the insulating body 1 . The shielding shell 30 covers the base portion u of the insulative housing 10 and the tongue plate 12, and is provided with a plurality of elastic pieces 31 extending into the shielding housing 30 and holding legs 32 extending into the circuit board 4. Further, referring to the seventh and eighth figures, when the electrical connector 1 is attached to the circuit board 4, the holding rib 170 closely interferes with the inner wall of the mounting hole 4 of the circuit board 4 at the horizontal periphery of the first positioning post 17 In order to prevent the electrical connector 1 from moving, the retaining rib 180 is in close interference with the inner wall of the circuit board 4 before and after the second positioning post 18 to make the electrical connector 1 non-rotatable. At the same time, the '$ two positioning post 18 is not convexly fixed along the line connecting it with the first positioning post 17, and the portion does not need to be connected to the positioning post 17, 18 (or the mounting hole 4〇). The inner wall of the garment hole 40 is tightly interfered with the fit, even if the positioning post 18 盥 the positioning post 17:18 (or the mounting hole 40) is connected to the circuit board 4 in a relatively tight connection with the package A. . In summary, the present invention has indeed met the requirements of the invention patent, and applied. However, the foregoing is only the preferred embodiment of the present invention = the scope of the present invention. Equivalent modifications or variations made by the inventor of the present invention are still covered by the appended claims. 1277261 BRIEF DESCRIPTION OF THE DRAWINGS The first figure is a three-dimensional combination of a conventional electrical connector.
