[0002] With the rapid development of science and technology in the electronics industry, the size of electronic products is developing in a trend of becoming thinner, lighter and shorter. This 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 next-generation USB Type-C connector is required to be smaller, which leads to stricter mechanical requirements and increased product design complexity. To meet the needs of thinner and lighter devices while ensuring product structural reliability, major manufacturers have launched corresponding structural designs.

[0004] The existing USB Type-C receptacle connector includes a plastic base, upper and lower rows of conductive terminals arranged on the plastic base, a shielding sheet sandwiched between the upper and lower rows of conductive terminals, and a shielding shell covered on the outside of the insulating body. A mutually cooperating limiting structure is provided between the shielding shell and the insulating body to combine the two. When the insertion force of the docking plug connector is too large, it is easy to cause the limiting structure to fail, thereby destroying the bonding force between the insulating body and the shielding shell, making the structural strength of the receptacle connector weak.

[0005] In view of this, it is necessary to improve the existing socket connector to solve the above problems. Utility Model Content

[0024] The present invention will be described in detail below with reference to 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 scope of protection of the present invention.

[0025] Please refer to Figures 1 to 6 Shown is a preferred embodiment of the socket connector 100 of the present invention. In the present invention, the socket connector 100 is installed on an external circuit board (not shown), and includes an insulating body 1, a plurality of conductive terminals 2 fixed in the insulating body 1, and a shielding shell 4 covering the outside of the insulating body 1.

[0026] Please refer to Figures 1 to 5 As shown, the conductive terminals 2 include a plurality of first terminals 21 whose contact portions 201 are arranged in a row and a plurality of second terminals 23 whose contact portions 201 are arranged in another row. The first and second terminals 21 and 23 are arranged in opposite directions, and the first terminals 21 and the second terminals 23 are arranged in the same manner as the conductive terminals in a standard USB Type C electrical connector.

[0027] Each of the conductive terminals 2 has a contact portion 201 exposed outside the insulating body 1 and solder legs 203 extending out of the insulating body 1 . The solder legs 203 of the first and second terminals 21 , 23 are arranged in two rows, front and back.

[0028] The shielding shell 4 has a first side wall 41 and a second side wall 42 arranged opposite to each other in the vertical direction. The first and second side walls 41 and 42 are spaced apart in the vertical direction. The first and second side walls 41 and 42 are provided with a first limiting portion 411 and a second limiting portion 421 protruding relatively. Figure 4As shown, the minimum spacing H between the first and second limiting portions 411 and 421 in the vertical direction ranges from 1.20 mm to 1.85 mm. In this way, when the plug connector is docked and the insertion force applied is too large, the plug connector can be prevented from being pushed into between the first and second limiting portions 411 and 412 due to excessive pressure, thereby avoiding damage to the insulating body 1.

[0029] For details, please refer to Figures 1 to 5 As shown, the insulating body 1 has a tongue portion 11 located on the front side, a base portion 12 located on the rear side, and a middle portion 13 connecting the tongue portion 11 and the base portion 12. The base portion 12 protrudes from the middle portion 13 in the up and down and left and right directions, and the first and second limiting portions 411 and 421 cooperate with the base portion 12.

[0030] The tongue portion 11 has two surfaces disposed in an upper and lower direction, and the contact portion 201 of the conductive terminal 2 is exposed on the upper and lower surfaces of the tongue portion 11, respectively. The tongue portion 11 also has a pair of protrusions 112 located on both sides of the tongue portion 11 in the transverse direction and protruding outward. The rear sides of the protrusions 112 are formed with a snap-fitting recess 113 for snapping with the mating connector.

[0031] The front end faces of the first and second limiting portions 411 and 421 are located in front of the front end face of the base portion 12. In this way, when the docking plug connector is plugged in, it will first abut against the front end faces of the first and second limiting portions 411 and 421, so that the shielding shell 4 bears the abutting pressure from the docking plug connector, thereby preventing the pressure during abutment from being directly applied to the insulating body 1, and further preventing the insulating body 1 from withdrawing backward from the shielding shell 4.

[0032] Furthermore, in this embodiment, the first and second limiting portions 411 and 421 are respectively formed by tearing from the first and second side walls 41 and 42 toward the interior of the shielding shell 4 .

[0033] Both ends of the first limiting portion 411 in the left-right direction are fixedly connected to the first side wall 41 , and both ends of the second limiting portion 421 in the left-right direction are fixedly connected to the second side wall 42 .

[0034] The base portion 12 is provided with a recessed portion 121 recessed rearward from its front end. The recessed portion 121 receives and limits the corresponding first and second limiting portions 411 and 421 .

[0035] The shielding shell 4 also has a pair of retaining plates 412 protruding from the first side wall 41 toward the interior of the shielding shell 4. The pair of retaining plates 412 are arranged opposite to each other in the left and right directions and are located on the rear side of the first limiting portion 411. The base portion 12 is recessed with a retaining groove 123 that is engaged with the retaining plates 412.

[0036] The first sidewall 41 is provided with a pair of first limiting portions 411 spaced apart in the left-right direction, and the second sidewall 42 is provided with a pair of second limiting portions 421 spaced apart in the left-right direction. The pair of retaining pieces 412 are positioned between the pair of first limiting portions 411 in the left-right direction. Furthermore, the first limiting portions 411 are provided in a one-to-one correspondence with the recessed portions 121, and the pair of retaining pieces 412 are received together in the same retaining groove 123.

[0037] In the present invention, the socket connector 100 also has an intermediate piece 3 located between the first terminal 21 and the second terminal 23 in the height direction. The intermediate piece 3 is a horizontally arranged sheet structure. The intermediate piece 3 is located between the contact portions 201 of the two rows of conductive terminals 2 in the height direction, and has a locking portion 31 protruding from both sides of the protrusion 112 in the left and right directions.

[0038] In the present invention, the receptacle connector 100 is provided with first and second limiting portions 411 and 421 protruding from each other on the first and second side walls 41 and 42, and the minimum spacing H between the first and second limiting portions 411 and 421 in the vertical direction is set to 1.20 mm to 1.85 mm. In this way, when the plug connector is mated and the insertion force applied is too large, the plug connector can be prevented from being pushed between the first and second limiting portions 411 and 412 due to excessive pressure, thereby avoiding damage to the insulating body 1. This ensures that the receptacle connector 100 has good structural strength and prevents the insulating body from being damaged by improper external forces.
