Abstract
The utility model relates to an electric connector, which comprises a body and a terminal arranged on the body. The utility model can solve the problems that insufficient terminal solder adsorption affinity in the process of surface adhering welding influences the control operation of manufacture processes and the jointing fixing performance of the terminal and the circuit board is poor. A welding surface on a terminal welding part of the utility model is at least provided with an installation part so as to absorb solder paste, so the solder paste contact surface of the terminal welding part in the process of surface adhering welding manufacture can be increased. Therefore, the adsorption affinity between the welding part and the circuit board can be increased, and the firm connection of the terminal and the circuit board after welding can be assured.
Description
The utility model is a kind of electric connector, especially refers to a kind of electric connector of strengthening engaging between terminal and circuit board fastness.
General electric connector all is via welding terminal to be fixed on the circuit board, and the solder technology that is adopted has through hole welding and surface adhering welding usually.Because surface adhering welding can make manufacture process speed up than the through hole welding, thus enhance productivity and the stay in grade cost low, get more and more so it is used.When surface adhering is welded usually, elder generation is at the surface coated tin cream of the desire welding of circuit board, then electronic component and electric connector are inserted in set welding position, make the tin cream fusing via the infrared ray heating again, last can be welded in it on both allocations of circuit board through cooling electronic components and electric connector.And the serviceability that fastness can influence electric connector that engages of electronic component and circuit board.When electric connector and butt connector grafting, it receives a contact engaging and separating force.If terminal is not enough to bear this contact engaging and separating force with the fastness that engages of circuit board, terminal is come off, cause electric connector normally not use.Figure 1 shows that the electric connector relevant with the utility model, this electric connector includes insulating body 5 and is installed on the conducting terminal 6 of insulating body 5, and wherein terminal 6 is provided with Plug Division 61 of docking with butt connector (not shown) and the weld part 62 that engages with circuit board (not shown).This weld part 62 is plane and welds to do the surface adhesion with circuit board, thereby electric connector is fixed on the circuit board.Yet, because of the weld part 62 of its terminal 6 is plane, make it in surface adhering welding manufacture process, have scolding tin to adsorb hypodynamic phenomenon, influence the manufacture process control operation, and then make its with circuit board to engage anchorage relatively poor, so that the phenomenon that terminal comes off takes place in the Chang Yuyu butt connector docking operation, cause this electric connector cisco unity malfunction, thereby reduce the quality of electric connector transmission.
The purpose of this utility model is to provide a kind of terminal and circuit board can reach firm engagement so that the electric connector of stablizing the telecommunication transmission to be provided.
The utility model includes body and terminal, and wherein body includes some installing spaces and the fixed part of being located on the installing space two side; And be installed on terminal in the body installing space comprise the Plug Division, relatively the Plug Division weld part and be located at the Plug Division and weld part between connecting portion, wherein this Plug Division tool one bending at least, and which is provided with plug surface and be extended with a rectangular projection in plug surface central authorities along its length direction, and the dual-side of weld part broad ways is provided with retaining piece with on the fixed part that is anchored on body, and its direction that deviates from the Plug Division is provided with solder side, it is characterized in that being provided with at least on this solder side an installation portion that can adsorb tin cream.
Relatively prior art adopts such scheme can increase the tin cream contact-making surface of terminal weld part in the surface adhering welding manufacture process, thereby increase the absorption affinity of weld part and circuit board, and then terminal is connected with the firm of circuit board after guaranteeing to weld.
Below in conjunction with legend and preferred embodiment, the utility model is described in further detail.

See also Fig. 2, Fig. 3 and shown in Figure 4 earlier, the utility model includes insulating body 1 and plurality of conductive terminals 2, wherein body 1 be provided with the abutment surfaces 11 of being abutted against circuit board 3, adjacent this abutment surfaces 11 and with the interface 12 that docks electric connector butt joint (not shown) and thus two sides 11,12 to the body 1 inner some installing spaces 13 that extend.This installing space 13 is Fang Tizhuan, and be provided with sidewall 131 in its both sides, this sidewall 131 is provided with a fixed part in installing space 13 and near abutment surfaces 11 places, in present embodiment, this fixed part is the groove 132 that is extended along the direction parallel with abutment surfaces 11 by interface 12.
See also Fig. 5 again, in second embodiment of the utility model electric connector, except terminal 2 ' weld part 22 ' solder side 222 ' different, second embodiment is provided with all the same with first embodiment.Two installation portions 223 of this solder side 222 ' be provided with ', this installation portion 223 ' be manhole.
Other sees also Fig. 6, in the 3rd embodiment of the utility model electric connector, except the solder side 222 of terminal 2 " weld part 22 ", and " different, the 3rd embodiment setting is also all the same with first embodiment.This solder side 222 " is provided with an installation portion 223 ", and this installation portion 223 " is an oval-shaped groove.
Claims (5)
1. electric connector, include body and terminal, wherein body includes some installing spaces and the fixed part of being located on the installing space sidewall, and terminal is installed in the installing space of aforementioned body, it includes the Plug Division, the weld part of Plug Division reaches the connecting portion between Plug Division and weld part relatively, wherein this Plug Division tool one bending at least, and which is provided with plug surface and be extended with a rectangular projection in plug surface central authorities along its length direction, and the dual-side of weld part broad ways is provided with on the fixed part that retaining piece can be anchored on body, and its direction that deviates from the Plug Division is provided with solder side, it is characterized in that being provided with at least on this solder side an installation portion that can adsorb tin cream.
