Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a vertical electrical connector that can be plugged in and out in both directions. Background Technology

[0002] An electrical connector is an electronic and electrical component mainly used to connect the receiving terminals in equipment or cables to transmit electrical signals or conduct electricity. Electrical connectors play a vital role in circuit connections, enabling the rapid assembly and use of wires, reducing the number of wires that need to be handled, and providing power protection and control functions.

[0003] Chinese utility model patent CN219833074U discloses a vertical connector, which is fixed vertically on a PCB board. The plastic terminal assembly includes a plastic part and several terminals integrally formed with the plastic part by embedded injection molding. One end of the terminal extends to the tail of the plastic part to form a pin for soldering to the PCB board. The pin is horizontally soldered to the pads on the PCB board. The plastic terminal assembly is covered with a metal shell. Several support pins extend downward from the tail of the metal shell and are inserted into corresponding limiting slots on the PCB board. A pair of positioning posts are also provided at the bottom of the plastic terminal assembly. Positioning holes that cooperate with the positioning posts to achieve rapid positioning are provided on the PCB board.

[0004] Compared with the above-mentioned existing technology, the support pins extending from the front, back, left, and right edges of the metal shell cooperate with the limiting slots on the PCB board, which greatly improves the accuracy of the connector installation position and the assembly firmness, and provides strong strength support for the male head when it is plugged in and out of the connector, preventing the connector from being skewed and damaged.

[0005] It should be noted that the above-mentioned prior art has the following drawbacks: the fastening and installation of the plastic terminal assembly requires the use of a metal housing, that is, the upright connector requires a metal housing assembly process. This increases the manufacturing and processing steps of the connector, and also increases the complexity of the overall connector structure and production cost. In addition, in the process of connecting with the PCB board, in addition to the soldering of the terminal pins, the support pins of the metal housing also need to be soldered, which involves many soldering steps. Utility Model Content

The connector body includes a terminal assembly and an insulating base, and the insulating base and the terminal assembly are injection molded into an integral structure.

[0009] The terminal assembly includes several spaced-apart mating terminals, the lower end of each mating terminal extending to the lower end of the insulating base and forming a terminal pin, and each terminal pin being soldered to the PCB board.

[0010] The terminal assembly consists of a front-side terminal group and a back-side terminal group. The upper ends of each mating terminal in the front-side terminal group are exposed on the front of the insulating base, and the upper ends of each mating terminal in the back-side terminal group are exposed on the back of the insulating base. The front-side terminal group and the back-side terminal group are arranged symmetrically.

[0011] The lower surface of the insulating base is provided with two positioning posts arranged at left and right intervals and protruding downwards respectively. One positioning post is located on the left side of the terminal assembly, and the other positioning post is located on the right side of the terminal assembly. The PCB board has vertical through positioning holes corresponding to each positioning post, and each positioning post is inserted and fixed in the corresponding positioning hole.

[0012] The insulating base is shaped like a "⊥" and includes a base and an insert portion that is disposed on the base and extends upward. The top view dimension of the base is larger than the top view dimension of the insert portion.

[0013] The upper end of each of the mating terminals is exposed on the outer surface of the mating part of the base, the terminal pins of each mating terminal extend to the lower end of the base, and each of the positioning pins is disposed on the lower surface of the base.

[0014] The front-side terminal group and the back-side terminal group adopt a double-row SMT structure layout, and the terminal pins of each of the mating terminals are surface mount pins, which are surface mount soldered to the PCB board.

[0015] The front-side terminal group and the back-side terminal group adopt a double-row DIP structure layout, and the terminal pins of each of the mating terminals are plug-in pins, which are respectively plugged into and soldered to the PCB board.

[0016] The connector body is a 26-pin connector structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects, specifically:

[0019] 1. The front side terminal group and the back side terminal group of this utility model are symmetrically arranged on both sides of the insulating base. The terminal assembly designed in this way supports arbitrary insertion and removal in both directions to improve the convenience of use.

That is, the connector body is fixed to the PCB board by soldering the terminal pins and fixing the positioning pins to the positioning holes. Compared with the prior art, the structure of this utility model is simpler, the corresponding assembly process is simpler, and the manufacturing cost is lower.

[0021] 3. Therefore, the upright electrical connector of this utility model that can be plugged in and out in both directions has the advantages of novel design, simple structure, simple manufacturing process and low manufacturing cost. Attached Figure Description

[0030] Example 1, as Figures 1 to 4As shown, a reversible pluggable upright electrical connector includes a PCB board 1 and a connector body 2 that is upright and fixed to the upper surface of the PCB board 1. The connector body 2 includes a terminal assembly and an insulating base 21, and the insulating base 21 and the terminal assembly are injection molded into an integral structure.

[0031] Among them, such as Figures 1 to 4 As shown, the terminal assembly includes a plurality of spaced-apart mating terminals 24, the lower end of each mating terminal 24 extending to the lower end of the insulating base 21 and forming a terminal pin 241, and each terminal pin 241 being soldered to the PCB board 1.

[0032] Furthermore, such as Figure 2 As shown, the terminal assembly consists of a front-side terminal group 22 and a back-side terminal group 23.

The PCB board 1 has vertical through positioning holes corresponding to each positioning post 211, and each positioning post 211 is inserted and fixed in the corresponding positioning hole.

[0034] In the assembly process of the reversible pluggable upright electrical connector in Embodiment 1, the two positioning posts 211 of the insulating base 21 are respectively inserted into and fixed in the corresponding positioning holes of the PCB board 1, and the terminal pins 241 of each mating terminal 24 are respectively soldered to the PCB board 1. That is, the connector body 2 of Embodiment 1 is fixedly connected to the PCB board 1 by soldering the terminal pins 241 and fixing the positioning posts 211 with the positioning holes. Compared with the prior art, since the reversible pluggable upright electrical connector of Embodiment 1 does not need to adopt a metal shell structure, the structure of the reversible pluggable upright electrical connector of Embodiment 1 is simpler, the corresponding assembly process is simpler, and the manufacturing cost is lower.

[0035] It should be further noted that, for the reversible pluggable upright electrical connector of this embodiment, the front side terminal group 22 and the back side terminal group 23 are symmetrically arranged on both sides of the insulating base 21.

[0042] Example 5, such as Figures 1 to 4 As shown, the difference between this fifth embodiment and the first embodiment is that the connector body 2 is a 26-pin connector structure.

[0043] Example 6 differs from Example 1 in that the positioning pin 211 and the positioning hole are interference-fitted.
