In addition, the connector of the present invention is not limited to the type depicted in fig. 1, and the worker in the field can adjust the type of each component according to the product requirement, or even increase or decrease the components, for example, the connector 1 may not be provided with the metal shell 14, or the metal shell 14 is integrated with the housing or other mechanisms of the product, and the worker in the field only needs to assemble the insulating body 10 together with the components thereon into the component equivalent to the metal shell 14, so as long as the connector 1 has the relevant basic structure and efficacy of the following embodiments, that is, the connector 1 to be protected of the present invention is described herein.

Referring to fig. 1-2, in the embodiment, an assembly space 140 is disposed in the metal housing 14, the insulating body 10 can extend into and be fixed to the assembly space 140, so as to achieve the effects of electromagnetic interference (EMI) prevention and protection of the insulating body 10 through the metal housing 14, and a socket 101 is disposed at the front side of the insulating body 10, an accommodating space 100 is disposed therein, and the accommodating space 100 and the socket 101 are communicated with each other. However, in other embodiments of the present invention, the insulation body 10 may not have the terminal groove 102, or a tongue plate may be added to the accommodating space 100 and the terminal groove 102 is formed on the tongue plate, according to the connector requirements of different specifications, which is not limited to the pattern shown in fig. 1.

Referring to fig. 1 and 3, the grounding middle plate 13 is located between the first metal terminal set 11 and the second metal terminal set 12, and is not electrically connected to the first signal terminal 111 and the second signal terminal 121, so as to avoid a short circuit. Furthermore, the present invention is characterized in that the rear ends of the first ground terminal 113 and/or the second ground terminal 123 are respectively provided with a folded-back

elastic piece

115, 125, and the

free sections

1151, 1251 of the folded-back

elastic pieces

115, 125 can be respectively abutted (e.g. simply abutted, welded, inserted and clamped) to the ground middle plate 13 to form an electrical connection (fig. 3 only depicts the pattern of the folded-back elastic piece 115 of the first ground terminal 113 abutting the ground middle plate 13), so that the connector 1 of the present invention can be more stable in performance when performing high-frequency and high-speed transmission, so as to meet the user's requirements, and will not excessively increase the overall volume of the connector 1.

As shown in fig. 1 and 3, since the folded

elastic pieces

115 and 125 are formed at the rear ends of the first ground terminal 113 and the second ground terminal 123, the forming is simple, the main structure of the

ground terminals

113 and 123 is not damaged, and the folded

elastic pieces

115 and 125 have a wide area, which is also beneficial to the subsequent welding operation. In addition, when the specification of the connector 1 is DisplayPort, although it has a plurality of ground terminals, only one ground terminal may have the folded-back elastic piece 115, for example, only the ground terminal corresponding to the second pin of DisplayPort may be used as the first ground terminal 113 of the present invention, but not limited thereto.

In order to avoid excessive wear of the metal terminals due to their material quality or length during transmission, the applicant also shortens the lengths of the

signal terminals

111, 121 and the

ground terminals

113, 123, i.e. the lengths of the

signal terminals

111, 121 and the

ground terminals

113, 123 of the present invention do not exceed the overall length of the insulating body 10, so that, referring to fig. 1 to 3, the applicant adds a circuit board E in the connector 1, the circuit board E can be located in the insulating body 10 (i.e. in the accommodating space 100), the rear ends of the first signal terminals 111 and the first ground terminals 113 can be soldered to the top surface and adjacent to the front side of the circuit board E (e.g. the soldering area E1 in fig. 1), the rear ends of the second signal terminals 121 and the second ground terminals 123 can be soldered to the bottom surface and adjacent to the front side of the circuit board E, the rear area of the circuit board E can be connected to other transmission lines, which has the following advantages:

(1) since the

signal terminals

111 and 121 and the

ground terminals

113 and 123 have short lengths, the loss rate can be reduced when signals or currents are transmitted;

(2) for the male end of the video connector (DisplayPort), the outer side of the video connector is usually provided with a key for a user to unlock by pressing the key when plugging, and the circuit board can replace a hollowed plastic area and has higher strength than plastic, so that the overall strength of the insulating body 10 can be effectively improved and the service life is longer; and

(3) the rear ends of the

ground terminals

113 and 123 can be soldered to the circuit board E, and the folded

elastic pieces

115 and 125 at the rear ends can be abutted to the ground middle plate 13, i.e., the ground loop between the ground middle plate 13 and the circuit board E is short, so as to form better grounding and anti-interference effects.

In view of the above, referring to fig. 1 and fig. 2, in this embodiment, the insulation body 10 can be composed of at least a front seat 10A and a rear seat 10B, and the rear side of the front seat 10A can be assembled with the front side of the rear seat 10B into a whole (as shown in fig. 2), so that the inner spaces of the front seat 10A and the rear seat 10B can jointly form the accommodating space 100, and the circuit board E can be conveniently disposed in the insulation body 10, as shown in fig. 1, the circuit board E can be inserted from the rear end of the front seat 10A, and the rear seat 10B can be assembled from the rear end of the circuit board E forward to the front seat 10A, so as to completely cover the circuit board E, thereby greatly improving the convenience of assembly.

Referring to fig. 1 and 3, in this embodiment, the

free sections

1151, 1251 of the folded-

back springs

115, 125 can be bent toward the circuit board E, that is, the free section 1151 of the folded-back spring 115 of the first ground terminal 113 is bent downward, and the free section 1251 of the folded-back spring 125 of the second ground terminal 123 is bent upward, so that one side of the folded-

back springs

115, 125 can be forwardly abutted against the rear side of the ground middle plate 13 (as shown in fig. 3), which is advantageous in that the distance between the rear side of the ground middle plate 13 and the front side of the circuit board E can have a high tolerance, and when the distance is too large or too small, the bending amplitude of the

free sections

1151, 1151 of the folded-

back springs

115, 125 can be adjusted by themselves to form a restoring force, so that the

free sections

1251, 1251 can be more tightly abutted against the ground middle plate 13, the situation that the folded-

back spring pieces

115 and 125 are not in contact with the grounding middle plate 13 and the expected grounding effect is lost is avoided.
