DETAILED DESCRIPTION
[0022] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices, systems, equipment and methods consistent with some aspects of the utility model.
[0023] refer to Figure 1As shown, the utility model provides a USB Type-C electrical connector that can be configured on consumer electronic products such as mobile phones, iPads and computers. The electrical connector includes an insulating body 1, a plurality of conductive terminals 2 fixed on the insulating body 1, and a metal shell (not shown). The insulating body 1 is provided with a longitudinal main body 11 and a tongue plate 12 extending forward from the main body 11, and the metal shell (not shown) is covered on the outside of the main body 11 and the tongue plate 12.
[0024] The plurality of conductive terminals 2 are divided into two rows, the upper and lower rows, and the insulating body 1 is provided with a plurality of terminal slots 13 for accommodating the conductive terminals 2. The tongue plate 12 includes a front section 121 and a rear section 122, the thickness of the front section 121 is thinner, and the plurality of terminal slots 13 pass through the body 11 and the rear section 122 of the tongue plate 12 and extend on the upper and lower surfaces of the front section 121 of the tongue plate 12. The conductive terminal 2 is inserted forward from the rear side of the body 11 and fixed in the terminal slot 13. The conductive terminal 2 includes a contact portion 21, a retaining portion 22 and a welding portion 23, and the retaining portion 22 connects the contact portion 21 and the welding portion 23. The contact portion 21 is located in the terminal groove 13 at the front section 121 of the tongue plate 12 and its surface is exposed to be electrically connected to the docking connector (not shown). The retaining portion 22 interferes with the inner wall of the terminal groove 13 at the main body 11 and / or the rear section 122 of the tongue plate 12 to fix the conductive terminal 2 to the insulating body. The contact portion 21 and the retaining portion 22 are located in the same horizontal plane, and the welding portion 23 is bent upward or downward from the retaining portion 22 and attached to the rear end surface of the main body 11 to be welded to the circuit board (not shown).
[0025] refer to Figures 2 to 4As shown, a plurality of conductive terminals 2 are formed by punching the same metal sheet. The conductive terminals 2 are arranged symmetrically about the left and right axes. The retaining portion 22 includes a guide portion 221 connected to the contact portion 21 and a bending portion 222 connected to the welding portion 23. The guide portion 221 gradually widens from front to back, and holes are dug on both sides of the bending portion 222 to form a narrow waist for easy bending. The portion of the terminal groove 13 that accommodates the guide portion 221 is defined as the retaining groove 131. The retaining groove 131 has a groove width a of equal width. The guide portion 221 has a minimum width b and a maximum width c, wherein the minimum width b is less than the groove width a of the retaining groove 131, and the maximum width c of the guide portion 221 is greater than the groove width a of the retaining groove 131 to interfere with the inner wall of the retaining groove 131. The minimum width b of the guide portion 221 is greater than or equal to the width of the contact portion 21. In this embodiment, the two are equal. The two opposite outer sides 223 of the guide portion 221 are inclined sides with a smaller slope. In this embodiment, the inclination angle r of the outer sides 223 is 2°, so the minimum width b and the maximum width c of the guide portion 221 are close to the slot width a of the retaining slot 131, and can have both the guiding and hard interference functions. The portion of the guide portion 221 with a width smaller than the slot width a provides a guiding function to prevent the conductive terminal 2 from shaking in the terminal slot 13; the portion of the guide portion 221 with a width larger than the slot width a provides a hard interference fixing function to fix the conductive terminal 2.
[0026] In this embodiment, the groove width a of the retaining groove 131 is 0.36mm, the minimum width b of the guide portion 221 is 0.25mm, and the maximum width c is 0.38mm, that is, the maximum value of the single-sided gap between the guide portion 221 and the retaining groove 131 is 0.055mm. The small gap can provide a guiding effect during the insertion of the conductive terminal 2. The single-sided interference dimension value between the guide portion 221 and the retaining groove 131 is 0.01mm, so as to avoid damage to the partition between the terminal grooves 13 due to excessive interference. It can be understood that the above dimensions can be adjusted within a small range, for example, the maximum value of the single-sided gap between the guide portion 221 and the retaining groove 131 is 0.045mm to 0.065mm; the single-sided interference dimension value between the guide portion 221 and the retaining groove 131 is 0.01mm to 0.02mm.
[0027] In this embodiment, the length d of the guide portion 221 is 1.86 mm. It is understandable that the slope range of the outer side 223 of the guide portion 221 can be set between 1.5° and 3°, and the length of the guide portion 221 can be adjusted accordingly, so that the single-side interference dimension value of the guide portion 221 and the retaining groove 131 is within a suitable range. Preferably, the length of the guide portion 221 is between 1.3 mm and 2.3 mm.
[0028] The above are only preferred implementation modes of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
