The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of escapable cost is provided, assembles simple electric connector.

For achieving the above object, the utility model provides a kind of electric connector, comprises an insulating body and several splicing ear groups.Insulating body offers several terminals storage tank and perforate; Several splicing ear groups are installed in respectively in the terminal storage tank, and each splicing ear group is made of a terminal and a butt terminal; This terminal is a spring-piece type, has a base portion, two and holds the kink that the terminal outward-dipping elastic arm that extends to form and two bends inwards and extends to form from an elastic arm end respectively from solid portion respectively from the holding parts, two that base portion one lateral buckling extends to form respectively; This butt terminal is a spring-piece type also, has the elastic arm that a bending part and two extends to form from bending part one side direction outer incline respectively, and two elastic arm ends bend inwards respectively and extend to form a holding section, and the both sides, holding section stretch out respectively and form an adjutage; Wherein, the holding section of butt terminal is resisted against the inboard place of corresponding elastic arm of a terminal slidably, kink can keep off holds adjutage, and the terminal elasticity of two elastic arms is resisted against on the cell wall of terminal storage tank, and bending part one end of butt terminal stretches out in the perforate of insulating body movably.

As mentioned above, the utility model electric connector is the mutual buckle of spring-piece type by seat terminal and butt terminal, and its project organization is simple, and assembling is simple, thereby saves cost.

Embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

See also Fig. 2 and Fig. 3, the utility model electric connector comprises an insulating body 10 and several splicing ear groups, and these several splicing ear groups comprise that respectively a seat terminal 20 and of making spring-piece type by spring production machine makes the butt terminal 30 of spring-piece type by spring production machine.

See also Fig. 2 to Fig. 4, described insulating body 10 roughly is rectangular-shaped, offer several perforates 11 on insulating body 10 roofs, upwards offer the terminal storage tank 12 that several are through to insulating body 10 roofs and are connected with a perforate 11 respectively from insulating body 10 diapires, offer holding slot 121 on terminal storage tank 12 sidewalls.

The seat terminal 20 of described spring-piece type has holding parts that a flat base portion 21, two extends to form from base portion 21 1 lateral bucklings respectively 22, two respectively from a holding parts 22 ends elastic arm 23 and two that forms of the diagonally extending kink 24 that bends inwards and extend to form from an elastic arm 23 ends respectively upwardly and outwardly, holding parts 22 both sides outwards convex with several latches 221, and kink 24 terminal edge center offer a fluting 241.

The butt terminal 30 of described spring-piece type has the elastic arm 32 that a bending part 31 and two extends to form from bending part 31 1 side direction outer inclines respectively, two elastic arms, 32 ends bend inwards respectively and extend to form a holding section 33, and 33 both sides, holding section stretch out respectively and form an adjutage 34.

The holding section 33 of the butt terminal 30 of the utility model electric connector is resisted against the corresponding elastic arm 23 inboard places of a terminal 20 slidably, elastic arm 32 passes the fluting 241 of a terminal 20, kink 24 can keep off holds adjutage 34, to prevent

abutment end

30 and 20 disengagements of seat terminal and to come off, seat terminal 20 and butt terminal 30 are placed in the terminal storage tank 12 of insulating body 10, the holding parts 22 of seat terminal 20 is immobilizated in the holding slot 121 of insulating body 10 by latch 221, two elastic arms, 23 terminal elasticity are resisted against on the cell wall of terminal storage tank 12, and bending part 31 1 ends of butt terminal 30 stretch out in the perforate 11 of insulating body 10 movably.

See also Fig. 3 and Fig. 4, during the work of the utility model electric connector, when butt connector pushing and pressing butt terminal 30, the elastic arm 32 of butt terminal 30 is subjected to the pushing and pressing effect of the elastic arm 23 of a terminal 20, thereby butt terminal 30 slides, when butt terminal 30 broke away from butt connector, the holding section 33 of butt terminal 30 pushed against in the elastic arm 23 of seat terminal 20 and slides into place, kink 24 belows.

In sum, the utility model electric connector is the mutual buckle of spring-piece type by seat terminal 20 and butt terminal 30, and its project organization is simple, and assembling is simple, thereby saves cost.
