Abstract

The utility model discloses an electric connector which is composed of an insulation noumenon and a conducting sheltering terminal. A sheltering groove used for sheltering conducting terminal is arranged on the insulation noumenon, the conducting electric terminal is composed of a subject part, a contacting part formed by extending upward the subject part, and a holding part formed by reversely bending the end of the subject part far away from the contacting to form an angle larger than 90 DEG. The holding part formed by reversely bending the end of the subject part far away from the contacting as an angle larger than 90 DEG can reduce the occupying area of the conducting terminal, and realize the small pitch arrangement of the conducting terminal in the insulation noumenon, which can guarantee the stably electric connections between the joint electrical elements.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector that can contact the realization electric connection with the abutment element compression.

[background technology]

The general electric connector that uses of industry comprises insulating body and conducting terminal, and insulating body is provided with the terminal containing slot of accommodating conducting terminal, and conducting terminal is contained in wherein.U.S. Patent number US5653598 has disclosed a kind of conducting terminal, it is located in the electric connector between relative contact mat, described contact mat is formed at respectively on IC encapsulation and the printed circuit board (PCB), its conducting terminal comprises the planar ends daughter with first, second interarea, this planar ends daughter comprises the elastic arm at a pair of interval, and it connects by an elastic surface neck.Each all has a free end described elastic arm, and this free end outer surface edge forms by terminal and supports end engaging corresponding contact mat, by free end towards each other direction extend and dislocation forms a pair of short circuit portion.When this structure reaches the punching press limit when the conducting terminal size, the pitch between the connector terminals (two terminal between spacing) can't dwindle, because the restriction of its structure, terminal can't realize that in insulating body little pitch arranges.

Therefore, be necessary to design a kind of novel electric connector,, satisfy the demands to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric connector, can obtain little pitch and arrange, and also can realize stable electric connection.

In order to reach above-mentioned creation purpose, the utility model electric connector comprises insulating body and conducting terminal, insulating body is provided with the accepting groove of accommodating conducting terminal, conducting terminal comprises main part, reach the contact site that extends upward setting by main part, oppositely form holding parts after the angles of bending one greater than 90 degree away from contact site one end by main part.

Compared with prior art, the utility model connector, main part oppositely forms holding parts after the angle of bending one greater than 90 degree away from contact site one end, can reduce the conducting terminal occupation space, can realize that the little pitch of conducting terminal in insulating body arranges, and can guarantee stable electric connection between the butt joint electronic component.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.

Referring to figs. 1 through shown in Figure 9, the utility model electric connector comprises insulating body 1 and conducting terminal 2, conducting terminal 2 accommodate with insulating body 1 in.

Insulating body is provided with the terminal containing slot 10 of accommodating conducting terminal, conducting terminal 2 comprises main part 20 and is extended upward by main part 20 and is provided with elastic arm 21, elastic arm 21 terminal extensions are provided with the contact site 22 that can contact with external chip (not icon) compression, oppositely form holding parts 23 after the angle of bending one greater than 90 degree (the reverse double flat of conducting terminal in the present embodiment) by main part 20 away from contact site 22 1 ends, holding parts 23 is roughly " U " shape, and holding parts 23 comprises that main part 20 reaches and the part 231 of main part doubling, the part 231 of described holding parts 23 and main part doubling extends upward and is provided with holding section 24, and holding section 24 is provided with shoulder 240 with holding parts 23 junctions.Conducting terminal 2 is roughly V-shaped after oppositely bending.Opening 25 of elastic arm 21 and the common formation in the plane at 24 places, holding section, opening 25 upwards climbs along terminal in order to anti-scolder when welding.The reverse double flat of conducting terminal, terminal can obtain little pitch arrangement like this, and can form long elastic arm 21, so that the butt joint chip provides enough elastic force with conducting terminal 2 compressions when contacting, both is fully contacted, and realizes stable electric connection.Conducting terminal 2 becomes to be staggered in insulating body, when even conducting terminal 2 pin numbers are a lot of like this, being staggered disperses extruding force, when conducting terminal 2 is retained in the insulating body 1, also can not produce the distortion of arching upward because of holding section 24 extruding insulation bodies 1 cause insulating body 1.

The accepting groove 10 of insulating body 1 forms rib 11 each other, rib 11 is disconnected a series of junior unit piece of formation at certain position, insulating body is when injection mo(u)lding like this, glass flows to non-directional, it is less to shrink, and the shrink degree of its all directions also is tending towards identical, when SMT welds, is subjected to pyrogenetic arch distortion less like this.Rib 11 disconnects and forms groove 12, when inserting accepting groove 10, conducting terminal 2 conducting terminal 2 is fastened in the accepting groove 10 fully in order to provide an application of force space to suppress conducting terminal 2 to mechanical device, press stop bit for simultaneously one of the upper end of holding section 24, the excessive pressure that conducting terminal 2 is unlikely to provide is provided and inserted the position, in conducting terminal 2 and tin ball 3 being offseted keep in position, thereby conducting terminal 2 is effectively contacted with circuit board (not icon).Its rib 11 disconnects also and to form the elastic arm 21 that allows bit space 13 make conducting terminal with conducting terminal 2 and can allow strain in the bit space 13, so that abutment element and conducting terminal 2 fully compress and contact and realize stable electric connection.Insulating body 1 back side is connected with tin ball 3, and tin ball 3 is close on the terminal limit and is fastened in the accepting groove 10.
