Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular, to a socket electrical connector.

Background Art

[0002] An electrical connector is a common electronic component on an electronic device, which is connected to a matching electrical connector on another electronic device to transmit signals and power between the two electronic devices. Regarding conventional electrical connectors, a Universal Serial Bus (USB) 3.1 electrical connector may be mentioned. In the current USB 3.1 protocol, the specification of the Type C electrical connector is newly added, which can provide a super-high-speed data transmission speed of 10 Gbps. Moreover, its volume is light and small, so it is suitable for portable devices such as mobile phones. The insertion port is symmetric and can be inserted in either direction, so it can be widely applied to various electronic devices.

[0003] The USB Type C socket electrical connector includes an insulating body, two sets of conductive terminals, and a metal housing. The insulating body is made of plastic, on which a tongue piece protrudes. Also, inside the insulating body, a metal piece for strengthening the tongue piece and shielding the signal between the two sets of conductive terminals is fitted to be injection-molded. The two sets of conductive terminals are provided on the tongue piece of the insulating body and can transmit signals. The metal housing covers the insulating body and the two sets of conductive terminals.

[0004] However, when implementing the injection molding process to fix the insulating body to the metal piece, when injecting and fixing the insulating body for a single metal piece and mass-producing the insulating body, a single device cannot simultaneously inject and fix a plurality of insulating bodies for a plurality of metal pieces. Since injection molding is performed on the metal pieces in sequence, it is difficult to efficiently mass-produce the socket electrical connector.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In view of the problems and defects of conventional socket electrical connectors, in order to improve them, the present inventor provides a new socket electrical connector.

[0006] The main object of the present invention is to provide an electrical connector. By performing secondary molding on the insulating body with respect to the first socket terminal group and the second socket terminal group, the stability of the structure for fixing each socket terminal to the insulating body is improved, the entire manufacturing process is optimized, and the yield rate is increased.

Means for Solving the Problems

[0007] To achieve the above object, the present invention provides a socket electrical connector, including a first socket terminal group, a second socket terminal group, an insulating body, and a housing. The first socket terminal group includes a plurality of first socket terminals connected and formed from a first molding member. The second socket terminal group includes a plurality of second socket terminals formed from a second molding member and covering a metal piece. A plurality of positioning blocks are formed on the surface of the second molding member. An isolation space for separating distances is defined between each of the positioning blocks by accommodating the first socket terminals. The metal piece is located between each of the first socket terminals and each of the second socket terminals. The insulating body is integrally secondarily molded with the first molding member and the second molding member, and includes a base, a step portion located on one side of the base, and a tongue plate extending outward from one side of the step portion. The first molding member is secondarily molded to be exposed on the surface of the step portion. Each of the first socket terminals and each of the second socket terminals are partially exposed on both side surfaces of the tongue plate. The housing defines an accommodation space for arranging the insulating body.

[0008] According to one embodiment of the present invention, two abutting blocks are provided on the top surface of the housing, which face each other and extend into the accommodation space.

[0009] According to one embodiment of the present invention, the base forms a concave groove for restricting the retraction distance of the housing by arranging and abutting the abutting block so as to face the stepped portion.

[0010] According to one embodiment of the present invention, at the tip of the top surface of the housing, two pressing springs are formed which face each other and are spaced apart, and at the tip of the bottom surface of the housing, two sealing protrusions are formed which face each other.

Modes for Carrying Out the Invention

[0012] As shown in FIGS. 1, 2, and 3, each is a three-dimensional structural schematic diagram in which the insulating body and the iron housing of the present invention are separated, a three-dimensional structural decomposition schematic diagram of the insulating body and the iron housing, and a three-dimensional structural decomposition schematic diagram of the insulating body, the first socket terminal group, and the second socket terminal group. The present invention relates to a socket electrical connector 1, mainly including a first socket terminal group 10, a second socket terminal group 11, an insulating body 12, and a housing 13. The first socket terminal group 10 includes a plurality of first socket terminals 100 formed by being connected from a first forming member 102. The second socket terminal group 11 includes a plurality of second socket terminals 110 formed from a second forming member 112 and covering a metal piece 14. A plurality of positioning blocks 1120 are formed on the surface of the second forming member 112. The spaced spaces 1122 defined between the positioning blocks 1120 accommodate the first socket terminals 100 to separate the distance. The metal piece 14 is located between each first socket terminal 100 and each second socket terminal 110 and is used to shield signals.

[0013] Also, the insulating body 12 is integrally combined with the first forming member 102 and the second forming member 112 by secondary molding, and includes a base 120, a step portion 122 located on one side of the base 120, and a tongue plate 124 extending externally from one side of the step portion 122. The first forming member 102 is exposed on the surface of the step portion 122 by secondary molding. Each first socket terminal 100 and each second socket terminal 110 are partially exposed on both side surfaces of the tongue plate 124. After combining the insulating body 12, the first socket terminal group 10, and the second socket terminal group 11, they are assembled into the accommodation space 130 of the housing 13.

[0014] As can be seen from the above, the insulating body 12 performs secondary molding on the first socket terminal group 10 and the second socket terminal group 11, thereby improving the structural stability of fixing each socket terminal to the insulating body, optimizing the entire manufacturing process, and increasing the yield rate.

[0015] As shown in FIGS. 4 and 5, it is a schematic plan view structure diagram of a preferred embodiment of the present invention and a schematic cross-sectional structure diagram of the A-A cross-sectional line in FIG. 4. Continuing with the above structure, as can be seen from the cross-sectional structure, two abutting blocks 134 that face each other and extend into the accommodation space 130 are provided on the top surface 132 of the housing 13. The concave groove 1220 formed on the base 120 so as to face the stepped portion 122 restricts the retreat distance of the housing 13 by arranging and abutting the abutting blocks 134. Further, two pressing springs 136 that face each other and are spaced apart are formed at the tip of the top surface 132 of the housing 13, and two sealing protrusions 139 that face each other are provided at the tip of the bottom surface 138 of the housing 13, thereby improving the insertion and extraction strength of a plug connector (not shown).
