[Prior art] 5 纟 电子 王 # 卜 电 连 ㈣ ”is electrically connected to the circuit on the circuit board. The electrical connector includes an insulating body that houses the terminals, and a shielding case for shielding external interference signals so that the terminals Able to transmit electrical signals normally, and a number of terminals fixed at one end in the insulating body, and the other end of the terminal is connected to an electrical circuit board. With the development of technology, electronic components are required to be more and more miniaturized, but each component is processed The amount of information is increasing, so you need to increase the density of the terminals per unit area of each electrical connector, but the density of the terminals extending from the electrical connector to the middle extension of the circuit board is very large. A slight external force will cause the terminal to shift, and it will be short-circuited to the adjacent terminal. In particular, the number of terminals led by the multi-layer electrical connector is larger, so it is 15 in the middle of the connection to the circuit board. The extension section is provided with a positioning protection device to isolate the terminals and prevent the terminals from being distorted or broken by external forces, making them short-circuited or open-circuited. Chinese Patent No. 00242727 3 discloses a stacked electrical connection Then, as shown in the first figure, the docking frame 9 is integrally formed with a [shaped] shape, and has an upright portion 91 and a horizontal portion%. Among them, the upright portion 91 is formed with a first connector that can be assembled A recessed portion 93 of 81 is formed through the recessed portion 93 below the recessed portion 93 to the boundary between the upright portion 91 and the horizontal portion 92. A receiving hole 94 is formed so that a second connector 82 can be assembled. Adu 94 is about the same as the overall height of the second connector 82, even 5 M240718 捌, the new description (2) is slightly larger than the overall height of the second connector 82, so that the second connector 82 can be easily inserted The first hole 811 provided in the accommodating hole 94 corresponding to the first connector 81 and the first terminal 821 provided in each second connector on the horizontal portion 92 are respectively provided with a plurality of first positioning holes. 921 and the second positioning 5 hole 922, when each connector is set up in the recessed portion 93 and the accommodation hole 94, its terminals can be inserted into the corresponding holes and protrude from the horizontal portion 92. Because of the docking frame 9 is a three-dimensional insulating frame, and there are several through holes and receiving grooves thereon. The requirements of the mold are relatively high, and each electrical connector must be mounted on the frame, which is more complicated to install. In addition, Taiwan Patent Application No. 872002919 discloses a laminated electrical connector. The combined structure of the connector, as shown in the second figure, includes a plurality of electrical connectors 7 and 72. A fixing member 73 and a terminal positioning base 74. The fixing member 73 is provided with at least one electrical connector housing. Xiao, put 15 electrical connectors 7 and 72 into the receiving groove 731 and then fix it to the fixing member 73. The terminal positioning base 74 is fixedly connected to the electrical connector 72. The terminal positioning base 74 is provided with several positionings. The hole 741 is used to receive the terminal extended in the electrical connector, so that the terminals protruding from the electrical connectors 71 and 72 fixed on the fixing member 73 pass through the positioning holes 74 on the terminal positioning base 74 so that the terminals Connect accurately to the board. The positioning protection device of this structure has a poor reliability because the terminal positioning seat therein is a three-dimensional three-dimensional component ′, but only its extension-end portion is connected to one of the electrical connectors. In addition, there are many places that need to be connected between each connector, the fixing member and the terminal positioning seat. However, since the terminals of each electrical connector 6 M240718 捌, the new specification (3) requires a high degree of fit with the positioning hole, ·:

[New content] Dreamfang provides an electrical connector with simple structure, low production cost, and safety, which can accurately and safely connect the terminals of the electrical connector to the circuit board. The main feature of the novel model is that the -U-shaped terminal positioning protection member is vertically fixed to the insulating frame of the electrical connector. The bottom wall of the U-shaped terminal positioning protection member is provided with several terminal positioning holes. The terminals extending from the insulating frame pass through these terminal positioning holes and are connected to the circuit board. At the same time, the two side walls of the υ-shaped terminal positioning protection member can protect the terminal from being impacted by external forces from the side, which strengthens the bare exposed insulation The positioning and protection of the terminals outside the frame ensure the circuit transmission of the terminals. Another feature of this new model is that in order to firmly connect the terminal positioning protection member to the insulating frame, it is considered that the upper and lower parts of the member are connected so that the bottom wall and both side walls of the U Φ member are insulated from each other. The frame-to-mouth connection means that at least one clamping block is protruded at the end of the protective member of the rafter bit near the insulating frame, and a slot is provided on the insulating frame corresponding to the clamping block. At least one positioning protrusion is provided on each end of the two side walls of the terminal fixed-position protective member fixedly matched with the clamping block near the insulating frame. The insulating frame is provided at a position corresponding to the protrusion. The positioning holes are matched with the positioning bumps. In this way, there will be no displacement between the terminal positioning protection member and the insulating frame in the up-down, left-right, and front-rear directions, which further ensures the safety of the terminal. M240718 新型, new description (4) One or more terminal housings can be protruded on the insulation frame of the new model. The terminal housing housing is covered with a shielding housing, which is used to shield external interference signals from the terminals. The terminals extending in the accommodating case are passed through the positioning holes on the terminal positioning retaining member, so that the terminals of a single electrical connector or a laminated 5 electrical connector can be positioned and protected. The novel model also includes a grounding member, which is used to connect the shielding body to the circuit board when it is a single electrical connector; when it is a laminated electrical connector, the shielding housings of the electrical connectors are first electrically formed. Connected and then connected to the circuit board, at the same time to achieve the effect of grounding, without the need to have a grounded design. 10 "Using the electrical connector combination of the above structure, because the insulating frame and terminal positioning protection block can be manufactured separately, Simplified manufacturing mold structure, low processing requirements, their installation method is also very simple and convenient, strong and reliable, stable, and the U-shaped structure of the terminal positioning protection member overcomes the defects of the existing 15 technology, making the protection of the terminal more In place, further guarantees electrical connection
