Abstract
The utility model discloses an electric connector, comprising a terminal block, a plurality of terminals and a metallic shell. The terminals are fixed in the terminal block. The metallic shell covers the terminal block. The terminal block comprises a mounting end and an abutting end. A groove is arranged at the mounting end of the terminal block. A via hole which is communicated with the terminal block's groove is arranged on the metallic shell. When the electric connector was molded in a plastic outer shell, the plastic can enter into the terminal block's groove through the via hole of the metallic shell, and the plastic outer shell and the electric connector are firm combined.
Description
[technical field]
The utility model discloses a kind of electric connector, refers to a kind of electric connector that is installed on the circuit board especially.
[background technology]
Development along with information industry, various portable type electronic products are more and more universal, flash disk (USBFlash Disk) has become one of portable type electronic product of popularizing the most in the market, exchanges data between itself and computer or other electronic products is by USB (USB, Universal SerialBus) connector is realized, announce a kind of USB socket of CN 2514510Y number announcement as Chinese patent, this socket comprises a holder, some transmission sheets, one metal shell, the transmission sheet is fixed in the holder, coats metal shell outside holder.It is outer to electrically connect with circuit board that the end that the transmission sheet is connected with circuit main board protrudes out holder.In addition, be installed in stability on the circuit board in order to strengthen this socket, one of method that industry adopted be with the installation end of this kind socket and the circuit board molding installed thereof in a plastic shell.Yet, because combining between plastic shell and the socket is firm inadequately, in the process that socket and other electronic components plug repeatedly, cause socket to separate easily with plastic shell, be installed in stability and the electric connection between the two on the circuit board thereby influence socket.
[utility model content]
The purpose of this utility model is to provide a kind of and is installed on the circuit board and the electric connector in circuit board is molded over a plastic shell, but plastic shell and electric connector strong bonded are installed in the stability on the circuit board to guarantee electric connector.
For achieving the above object, the utility model adopts following technical scheme: a kind of electric connector comprises terminal base, plurality of terminals and metal shell.Terminal base comprises an installation end and a butt end.Terminal is fixed in the terminal base, and metal shell is coated on the terminal base.The installation end of terminal base offers groove, offers through hole on the metal shell and is connected with the groove of terminal base.
Compared with prior art, the utlity model has following advantage: after the utility model is installed on the circuit board, in the time of in circuit board takes shape in plastic shell, in the groove of through hole upstream end stroma that the part plastic cement can be by metal shell, plastic cement seat and electric connector are combined securely, improve electric connector and be installed in stability on the circuit board, guaranteed the electric connection between electric connector and the circuit board.

Fig. 2 is the schematic perspective view of another angle of the utility model electric connector.
Fig. 3 is the three-dimensional exploded view of electric connector shown in Figure 1.
[embodiment]
See also Fig. 1 to shown in Figure 3, the utility model electric connector 100 comprises metal shell 1, terminal base 2 and plurality of terminals 3.Terminal base 2 comprises installation end 20, butt end 21, upper surface 22, lower surface 23 and some passages 24 of accommodating.Upper surface 22 is provided with first groove 220 and buckle slot 222, and lower surface 23 is provided with a pair of second groove 230.Terminal 3 is contained in the terminal base 2, and each terminal 3 includes weld part 30, docking section 32 and connects the pars intermedia 31 of weld part 30 and docking section 32, and pars intermedia 31 is provided with retaining sheet 33.Weld part 30 stretches out the installation end 20 of terminal base 2, and pars intermedia 31 is contained in accommodates in the passage 24, and retaining sheet 33 and the inwall interference engagement of accommodating passage 24 are to be retained on terminal 3 in the terminal base 2.
When metal shell 1 is coated on the terminal base 2, first through hole of offering on the roof 11 of metal shell 1 110 is connected with first groove 220 on terminal base 2 upper surfaces 22, second through hole of offering on the diapire 12 of metal shell 1 120 is connected with second groove 230 on terminal base 2 lower surfaces 23, buckle slot 222 interference engagement of 112 of the clamping parts of metal shell 1 and terminal base 2 are to be retained on metal shell 1 on the terminal base 2.
During use, the installation end 20 of terminal base 2 is installed on the circuit board (not shown), corresponding contact mat electrically connects on the weld part 30 of terminal 3 and the circuit board, electric connector 100 is molded in the plastic shell together near an end of circuit boards and the circuit board of being installed thereof again.In the process of injection mo(u)lding, in first groove 220 on second through hole, 120 upstream end stromas, 2 upper surfaces of offering on first through hole of offering on the roof 11 of plastic cement by metal shell 1 110, the diapire 12 22, second groove 230 on the lower surface 23, after the moulding, plastic cement in first, second groove 220,230 of this part upstream end stroma 2 is with electric connector 100 and firm the combining of plastic shell, and then increase electric connector 100 and be installed in stability on the circuit board, dock accurately to guarantee that electric connector 100 docks with other between electronic component.
