Detailed Description

The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

Referring to fig. 1, a high-speed orthogonal connector includes two sub-connectors that are matched with each other, one of the sub-connectors defining a contact end of a signal terminal in a receiving cavity shape or a shape that the contact end functions as a receiving cavity is a bent female connector 10, and the other sub-connector defining a contact end of a signal terminal in a received shape and forming a needle shape is a bent male connector 20, where "bent" means that two end faces of the connector are bent at 90 °.

Referring to fig. 2, the curved female connector includes a plurality of curved female wafers 101 distributed in parallel, a curved female signal terminal 102 on the same curved female wafer has a contact end, a crimping end, and a terminal body connecting the contact end and the crimping end, and the terminal body and the contact end are in a broadside coupling form (as shown in fig. 5); the bent male connector comprises a plurality of bent male wafers 201 which are distributed in parallel, a bent male signal terminal 202 on the same bent male wafer is provided with a contact end, a crimping end and a terminal body for connecting the contact end and the crimping end, the bent male signal terminal is in a narrow-side coupling form from the contact end to the crimping end (as shown in figure 4), and the effect of orthogonal connection is just achieved by means of the form of 'one wide and one narrow' of the contact end, because the concept of 90-degree turning is embodied by 'wide-side coupling' and 'narrow-side coupling', the high-speed orthogonal connector provided by the scheme can be directly plugged without bending the contact end of the signal terminal by 90 degrees, an orthogonal connection structure is naturally formed (the action process is defined as 'natural orthogonal'), and the technical problem that the contact end of the signal terminal of one sub-connector in the existing orthogonal connector must be bent by 90 degrees is fundamentally solved, thereby overcoming the defect caused by the bending process adopted by the contact end of the signal terminal. Of course, in other embodiments, the contact end and the terminal body of the bent female signal terminal in the bent female connector may be in a narrow-side coupling form, and the contact end and the terminal body of the bent male signal terminal in the bent male connector may be in a wide-side coupling form.

Referring to fig. 3, 6 and 7, the male signal terminal 202 of the male connector is formed by cutting a metal strip, and the contact end 2021 thereof has a rough cut-out surface 20211 and a smooth non-cut-out surface 20212; the contact ends 1021 of the bent female signal terminals 102 of the bent female connector are configured as gripping portions having an upper jaw 10211 and a lower jaw 10212. If the cutting surface of the bent male signal terminal is clamped by the clamping part, because the cutting surface is rough, under the condition of repeated pulling and inserting friction, the cutting surface can generate worn debris, the debris can be attached to the contact end in the form of a metal wire, various accidental short circuits of the contact end can be caused, for example, the adjacent signal ends are overlapped, or the signal end and the grounding end are overlapped, the signal end loses the signal transmission effect, and a communication system using the orthogonal connector generates serious error codes, and when the bent male connector and the bent female connector are oppositely inserted, the upper clamping piece 10211 and the lower clamping piece 10212 are in pressing contact with the smooth non-cutting surface 20212, so that the worn debris can not be generated during pulling and inserting, and the short circuit phenomenon can be eliminated.

The contact end of the bent female signal terminal is formed by horizontally bending materials on the upper side and the lower side of two terminal bodies included in one signal differential pair respectively, for example, the materials are horizontally bent outwards, and the shape of the formed contact end is shown in fig. 7; or bending the material horizontally inwards to form a contact end shape as shown in figure 8A; or the material on the upper side and the lower side of one terminal body is horizontally bent outwards, and the material on the upper side and the lower side of the other terminal body in one differential pair is horizontally bent inwards. Furthermore, the contact end of the bent female signal terminal includes two auxiliary clamping portions 10213 oppositely distributed on the same side surface of the upper clamping piece and the lower clamping piece, for example, if one side surface of the upper clamping piece and the lower clamping piece is provided with an auxiliary clamping portion, the cross section of the contact end at the auxiliary clamping portion is U-shaped (as shown in fig. 8D and 8E); two side surfaces of the upper clamping piece and the lower clamping piece are respectively provided with an auxiliary clamping part, the corresponding cross section is O-shaped (as shown in figures 8B and 8C), the two auxiliary clamping parts are used for improving the strength of the contact end and are respectively contacted with the upper non-cutting surface and the lower non-cutting surface after being separated in a mutual insertion state, and the contact area of the bent male signal terminal and the bent female signal terminal is increased.
