Abstract
The utility model discloses an electric connector, comprising an isolation body, a plurality of terminals housed in the isolation body, and solders connected to the terminals. The isolation body is provided with a support structure. The support structure can bunt the terminals when the terminals are deformed by compression, so as to lower the contact resistance and guarantee the effective contact between the terminals and the foreign components.
Description
Technical field
The utility model relates to a kind of electric connector, the electric connector that especially a kind of and external assembly compression contacts.
Background technology
As shown in Figure 1, 2, existing electric connector comprises insulating body 2 and the some terminals 3 that is located in this holding tank 1 that is provided with some holding tanks 1.This terminal 3 comprises a fixed part 4, is extended upward the elastic arm 5 that obtains, extended the strip linking arm 6 that forms by elastic arm 5 one lateral bucklings by fixed part 4, and then bend 90 welding endss 7 that obtain of degree by fixed part 4 downward extensions, to connect scolder 8, as the tin ball.During with external assembly assembling (not drawing among the figure), external assembly is pressed from top to bottom, be electrically connected thereby reach with the contact jaw 9 of elastic arm 5 ends.But this electric connector exists three defectives at least: the first, and the terminal strength of this termination contact arm is less, causes the terminal positive force less, thereby causes contact resistance bigger, even may influence terminal and contact with the effective of external assembly; The second, under the certain situation of electric connector height, the length of this fixed part is less, thereby it is firm to cause terminal and insulating body to fix; The 3rd, this terminal needs through repeatedly bending process, the processing more complicated.
Summary of the invention
The purpose of this utility model is to provide a kind of electric connector, and it can reduce contact resistance, and can guarantee that terminal effectively contacts with external assembly.
Another purpose of the present utility model is to provide a kind of electric connector, and it can guarantee that terminal and insulating body are fixed together securely.
Another purpose of the present utility model is to provide a kind of electric connector, and it is easy to process, low cost of manufacture.
For achieving the above object, the utility model electric connector comprises insulating body and some terminals that is located in this insulating body, this insulating body is provided with supporting construction, this supporting construction can be lived terminal by butt when the terminal compressive deformation, thereby can reduce contact resistance, and can guarantee that terminal effectively contacts with external assembly.

Embodiment
Below in conjunction with accompanying drawing the utility model electric connector is further detailed.
Shown in Fig. 3 to 6, this electric connector comprises the insulating body 20 that is provided with plurality of terminals accepting groove 10, and some terminals 30 that is inserted in the terminal containing slot 10.This terminal 30 comprises main body 32 and the fixed arm 34 that is extended upward out respectively by main body 32 1 sides, elastic arm 36 and the weld part 38 that extends out downwards, these fixed arm 34 middle parts are provided with a shell fragment of outwards going out 35, terminal is fixed on the insulating body 20, this elastic arm 36 is roughly to bend earlier 90 degree backward by main body 32, and then bend one forward less than 90 angles of spending, tilt to form certain angle with insulating body 20 upper surfaces, and its end protrudes in fixed arm 34 tops, and be bent into arc again, form contact site 37, to contact with external assembly (not drawing among the figure), this contact site 37 is the jag shape, contacts to reach at 2 with external assembly.This weld part 38 is " ㄇ " shape, can be embedded to connect a scolder, as the tin ball.One side of this insulating body 20 sub-elastic arm 36 in the host side vertically is provided with supporting construction 22, this supporting construction 22 is the rib shape, its top is tip-angled shape, the top is lower than the insulating body upper surface, and the height of this supporting construction 22 should satisfy when external assembly is oppressed terminal 30, and this terminal 30 can touch supporting construction 22.This insulating body 20 is provided with one " V " shape opening 24 on a side top of accommodating terminal fixed arm 34, the strip so that fracture, and corresponding shell fragment 35 offers a groove 26, inserts and cooperates the purpose that reaches fixed terminal 30 with shell fragment 35 on the terminal fixed arm 34 with guiding terminal 30.
When assembling with external assembly, external assembly can move down by the sub-elastic arm 36 in pressure side, when moving to the precalculated position, this supporting construction 22 can touch and butt is lived terminal elastic arm 36, when further being moved down, elastic arm 36 needs bigger strength, make between terminal 30 and the external assembly to have bigger positive force, thereby can reduce contact resistance, and can guarantee that terminal 30 effectively contacts with external assembly; And this terminal fixed arm 34 can be made longly, and by Elastic buckle that terminal 30 is fixing with insulating body 20, thereby can guarantee that terminal 30 is fixed in the insulating body 20 securely; Moreover 30 need of this terminal just can obtain through twice bending, and are than existing terminal, much easy to process.
