Technical Field

[0001] The utility model relates to an electric connector. Background Art

[0002] With the rapid development of science and technology in the electronics industry, the size of electronic products is developing along the trend of becoming thinner, lighter and shorter, which requires the size of components of electronic products to become smaller and smaller, and the connector industry is the first to bear the brunt.

[0003] The new generation of USB Type-C connectors are required to be smaller in size, which leads to better requirements for mechanical performance and higher difficulty in product design. In order to target thinner and more slender devices and ensure the reliability of product structures, major manufacturers have launched corresponding structural designs. When the existing USB Type-C plug connector uses assembled terminals, it is difficult to assemble and position the conductive terminals and locking parts with the insulating body. In addition, since the locking parts are provided with a protruding structure that extends forward and matches the insulating body, the insulating body needs to be provided with a corresponding receiving groove to accommodate the protruding structure, which further reduces the wall thickness of the insulating body and weakens its structural strength.

[0004] In view of this, it is necessary to improve the existing electrical connector to solve the above problems. Utility Model Content

[0025] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on the embodiments are all within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 8 The figure shows a preferred embodiment of the electrical connector 100 of the present invention. The electrical connector 100 comprises an insulating body 1 , a plurality of conductive terminals 2 fixed in the insulating body 1 , and a locking member 3 installed in the insulating body 1 .

[0027] Please refer to Figure 1 , Figure 2 and Figure 8 As shown, the insulating body 1 comprises a base 11 and a mounting portion 12 located at the rear side of the base.

[0028] Please refer to Figure 1 , Figure 2 and Figures 7 and 8 As shown, the conductive terminal 2 includes first terminals 2a and second terminals 2b whose contact portions 201 are arranged in two rows in the height direction, and the contact portions 201 of the first and second terminals 2a, 2b are arranged in opposite directions.

[0029] In the embodiment shown in the utility model, the first terminal 2a and the second terminal 2b arranged opposite to it in the height direction are arranged independently of each other. In other embodiments of the utility model, the first terminal 2a and the second terminal 2b arranged opposite to it in the height direction can also be connected as a whole to form a conjoined terminal. Specifically, in the utility model, the position setting of the contact portions 201 of the two rows of conductive terminals on the insulating body 1 is the same as the position setting of the docking portion of the corresponding terminal on the standard USB Type-C plug connector.

[0030] In the present embodiment, the first terminal 2a and the second terminal 2b each have twelve conductive terminals, which are respectively: a first ground terminal (Gnd), a first pair of high-speed signal terminals (TX1+-, differential signal terminals, used to transmit high-speed signals), a first power terminal (Power / VBUS), a function detection terminal (CC1, used to detect the function of forward and reverse insertion and identify the function of CABLE), a pair of low-speed signal terminals (D+-, differential signal terminals, used to transmit low-speed signals), an expansion terminal (SBU1, which can be defined for other purposes), a second power terminal (Power / VBUS), a second pair of high-speed signal terminals (RX2+-, differential signal terminals, used to transmit high-speed signals) and a second ground terminal (Gnd), and the signal terminals (function detection terminals, low-speed signal terminals and expansion terminals) between the two power terminals can be set according to application requirements.

[0031] Please refer to Figures 3 to 8 As shown, the locking member 3 includes a cross beam 31, a pair of locking arms 32 extending forward from the cross beam 31, a pair of welding legs 33 extending backward from the cross beam 31, and a pair of protruding arms 34 extending forward from the cross beam 31, wherein the thickness of the pair of protruding arms 34 in the up-down direction is smaller than the thickness of the cross beam 31 in the up-down direction. Thus, by thinning the protruding arms 34, the space occupied by the protruding arms in the insulating body 1 is saved, thereby improving the structural strength of the insulating body 1.

[0032] In this embodiment, the protruding arm 34 may be thinned to obtain a thickness thinner than the crossbeam 31 . In other embodiments, other methods may also be used.

[0033] The insulating body 1 has a first receiving groove 101 for receiving the beam 31 and a second receiving groove 102 connected to the first receiving groove 101 for receiving the corresponding protruding arm 34. The height of the second receiving groove 102 in the vertical direction is smaller than the height of the first receiving groove 101 in the vertical direction.

[0034] Specifically, a step portion 301 is formed at the intersection of the protruding arm 34 and the cross beam 31. Preferably, in this embodiment, the step portion 301 is provided at the intersection of the upper and lower sides of the protruding arm 34 and the cross beam 31.

[0035] Specifically, the distance from the upper surface 342 of the protruding arm 34 to the horizontal center plane C-C' of the electrical connector 100 is smaller than the distance from the upper surface of the beam 31 to the horizontal center plane C-C', and / or the distance from the lower surface 343 of the protruding arm 34 to the horizontal center plane C-C' of the electrical connector 100 is smaller than the distance from the lower surface of the beam 31 to the horizontal center plane C-C', so that the orthographic projection of the protruding arm 34 on the mating end face of the electrical connector 100 is located inside the orthographic projection of the beam 31 on the mating end face.

[0036] In the embodiment shown in the present invention, the upper and lower surfaces 342 and 343 of the protruding arm 34 are both arranged parallel to the horizontal center plane CC' of the electrical connector 100. In other embodiments of the present invention, the upper and lower surfaces of the protruding arm 34 may also be non-parallel to the horizontal center plane CC', that is, the upper and lower surfaces are both inclined, and the thickness of the front side of the protruding arm 34 is smaller than the thickness of the rear side.

[0037] Each of the protruding arms 34 has a first end connected to the crossbeam 31 and a second end disposed opposite to the first end in the front-rear direction. The protruding arm 34 is provided with a pair of inclined guide surfaces 341 at the second end, and the pair of guide surfaces 341 are disposed oppositely at the upper and lower sides of the protruding arm 34. The first end is the rear end of the protruding arm 34, and the second end is the front end of the protruding arm 34, that is, the free end thereof. The upper and lower surfaces 342 and 343 of the protruding arm 34 are the parts thereof excluding the guide surfaces 341.

[0038] The first pair of high-speed signal terminals are arranged corresponding to one protruding arm 34, and the second pair of high-speed signal terminals are arranged corresponding to another protruding arm 34, and the first and second pairs of high-speed signal terminals are respectively located within the width range of the corresponding protruding arms 34 in the lateral direction, so as to enhance the high-frequency performance of the electrical connector 100.

[0039] In addition, in the present invention, the locking member 3 also has a pair of extension arms 35 extending backward from the cross beam 31, and the pair of extension arms 35 are located on the outside of the welding foot 33 in the transverse direction, and each of the extension arms 35 and the welding foot 33 on the same side are spaced apart in the transverse direction. In this way, by arranging the extension arms 35 located on the outside and spaced apart from the welding foot 33, the locking member 3 is prevented from being deflected when inserted into the insulating body 1, and at the same time, it can ensure that the locking member 3 is subjected to balanced force.

[0040] Furthermore, the width of the interval between the extension arm 35 and the welding foot 33 on the same side in the transverse direction is greater than the width of each extension arm 35 in the transverse direction, and smaller than the width of each welding foot 33 in the transverse direction.

[0041] Specifically, Figure 6 As shown, the width of the extension arm 34 in the transverse direction is smaller than the width of the welding foot 33 in the transverse direction. Further preferably, in this embodiment, the width of the interval between the extension arm 34 and the welding foot 33 on the same side in the transverse direction is larger than the width of each extension arm 34 in the transverse direction, and smaller than the width of each welding foot 33 in the transverse direction, thereby ensuring the structural strength of the welding foot 33, and at the same time using the outer extension arm 34 to ensure the balance of the locking member 3 during insertion, to avoid spinning during insertion.

[0042] In addition, the cross beam 31 as a whole extends in the transverse direction. In some embodiments, the cross beam 31 is covered with an insulating block (not shown) to avoid the risk of overlap between the locking member 3 and the power terminal. In other embodiments, the insulating block may not be provided outside the cross beam 31.

[0043] In this embodiment, the pair of solder feet 33 are soldered to different sides of the circuit board (not shown) in the up and down directions, that is, the pair of solder feet 33 are placed on both sides of the beam 31 in the height direction, and the solder feet 33 extend backward beyond the rear end surface of the extension arm 34, and the extension arm 34 does not extend backward beyond the rear end surface of the insulating body 1.

[0044] Furthermore, in some embodiments of the present invention, the electrical connector 100 also has a shielding shell 4 that is sleeved outside the insulating body 1, and the extension arm 35 and the welding foot 33 are accommodated and limited between the inner wall surface 41 of the shielding shell 4 and the side wall surface 123 at the rear of the insulating body 1.

[0045] The electrical connector 100 of the present invention is provided with a pair of protruding arms 34 extending forward from the cross beam 31, and the thickness of the protruding arms 34 in the vertical direction is made smaller than the thickness of the cross beam 31 in the vertical direction, thereby saving the space occupied by the protruding arms 34 in the insulating body 1 and improving the structural strength of the insulating body 1.
