Description

Multi-slot BTB connector capable of being plugged in and unplugged from front and back, and terminal

Technical Field

The utility model belongs to the technical field of the connector technique and specifically relates to a but many slots BTB connector of positive and negative plug and terminal.

Background

The BTB connector is mainly used for connecting PCBs inside mobile phones and notebook computers with signals such as Bluetooth, hard disk flat cables and touch mouse boards, belongs to a high-precision multi-contact connector, and has specifications of 0.5mm, 0.8mm, 1.0mm, 1.27mm, 2.0mm, 2.5mm spacing and the like on the market at present.

Currently, BTB connectors produced by BTB connector manufacturers generally include a pair of male and female terminals, and the male and female terminals are usually in a single blanking structure.

The blanking structure is that when the terminal is processed, a piece of hardware plate is subjected to plane shearing, unnecessary plates are dug out, and male and female terminals required by molding are manufactured.

Therefore, in the whole processing process of the terminal, no stretching and bending treatment is carried out on the hardware material, and the elastic force of the terminal formed in a blanking mode is poor.

The existing BTB connector has a male terminal and a female terminal of a blanking structure, and a male body and a female body for assembling and fixing the male terminal and the female terminal respectively. The two longitudinal sides of the male end main body are respectively provided with a terminal fixing hole and a terminal positioning groove for riveting a male end terminal; the female end body is provided with a groove for butt joint insertion of the male end body, and the female end body is provided with a plurality of terminal fixing holes (not marked) and terminal positioning grooves for riveting the female end terminals relative to the longitudinal two sides of the other surface of the groove. The male terminal is in a shape of a horizontal F, and each male terminal has three ends, wherein two ends of each terminal form a notch, and a contact area is formed on the outermost end. The male terminal and the female terminal are respectively clamped in the terminal fixing holes and the positioning grooves formed in the male terminal main body and the female terminal main body by the notches to assemble a male terminal and a female terminal of the BTB connector (or integrally injection molding). During the mating operation, the male end is pressed into the recess in the female end body, so that the terminal contact area forms a close connection.

For example, patent CN109346860A discloses a terminal of BTB connector and a BTB connector, which comprises a holder having a first card strip, a placement slot and a PIN slot, and a spring piece having a spring piece head, an elastic piece and a fixing piece, which is inserted into the holder through the placement slot; the head of the elastic sheet is inserted into the PIN slot hole and exposed out of the fixed seat; the fixing piece comprises a spring plate clamping hook meshed with the first clamping strip; the elastic member includes at least one elastic portion.

Patent CN109950716A discloses a floating BTB connector, which is composed of a male socket part and a female socket part that are inserted into each other, wherein the male socket part includes a male socket insulator, a male socket cover and a male socket terminal; the male seat insulator is of a cavity structure, and a plurality of male seat clamping grooves are uniformly distributed on the front inner side wall and the rear inner side wall of the male seat insulator and used for inserting the male seat terminals; the female seat part comprises a female seat insulator and a female seat terminal; a plurality of female seat clamping grooves are uniformly distributed on the female seat insulator; the female seat clamping groove is used for inserting the female seat terminal and corresponds to the male seat terminal in position one to one, the male seat terminal is a bent elastic piece and sequentially consists of a lower PCB welding part, a male seat insulator inserting part matched with the male seat clamping groove, an elastic bending part and a male seat insulator supporting part, and correspondingly, an inserting part matched with the male seat insulator supporting part is arranged on the male seat cover; the male seat cover is sleeved in the cavity of the male seat insulator, is not in contact with the male seat insulator completely, and is supported only by the male seat insulator supporting part; when the male seat part is inserted relative to the female seat part, the position of the male seat cover relative to the male seat insulator can be finely adjusted in the X direction and/or the Y direction by means of the elastic bending part, so that the male seat terminal has a correct inserting position relative to the female seat terminal.

However, the BTB connector disclosed in the above patent has a problem that the card can be inserted only from one end, and has no function of preventing erroneous insertion, and is very inconvenient to use, and the card may be damaged during the erroneous insertion.
