The electric connector body is a bar-shape base body whose upper end is arranged with a plugging slot. The inner portions of the two side walls of the plugging slot are arranged with a plurality of terminal slots in separated arrangement and each terminal slot is communicated with the plugging slot. Each terminal is arranged with a terminal body portion whose upper end is inward arranged with a guiding connection elastic plate in bending. The inner side of the lower end of each terminal body portion is convexly arranged with a contacted portion in bending. A plurality of terminals are respectively arranged in the terminal slots of the electric connector body and the contacted portion of each terminal convexly extends to the plugging slot bottom of the electric connector body and the terminals are downward pressed and the contacted portion is in swinging state. When the circuit board card in inserted into the utility model, the guiding connection elastic plate can inward clamp/contact the board end connecting point of the circuit board card by the circuit board is downward pressed to the contacted portion to reduce the compression size of the guiding connection elastic plate and prevent the upward pulling frictional force of the bearing circuit in order to improve the service life of the electric connector.

Technical field
The utility model relates to a kind of electric connector, particularly a kind of clamp type electric connector.
Background technology
Known electric connector, it is a kind of electronic component that provides circuit-board card or various plug to peg graft fast, therefore have multiple multi-form on structure is formed, see also shown in Figure 5, the electric connector 100 that can provide circuit board to peg graft for commonly seeing, often be applied to computer motherboard or test with occasions such as motherboards, mainly include the insulating body 10 of a strip, 10 upper end central authorities are provided with a slot 101 in insulating body, in these slot 101 two sides, be provided with plural spaced terminal groove 102, in each terminal groove 102, be installed with one by this and connect terminal 20, wherein, this connects terminal 20 tops and is provided with a lead coupling spring lamination 201 that is stretched on slot 101, and its lower end is provided with a pin 202 that is stretched on insulating body 10 belows, by this electric connector that can peg graft fast of built-up circuit integrated circuit board 30.
Above-mentioned electric connector structure of commonly seeing, be with the lead coupling spring lamination 201 on terminal 20 tops when circuit-board card 30 inserts, the plate tip node 301 that can contact at circuit-board card 30 is said golden finger structure, therefore in bending place, lead coupling spring lamination 201 upper end, often bear the stress of circuit-board card 30 plugs, and cause taking place easily lead coupling spring lamination 201 elastic fatigues or crack conditions; And when circuit-board card 30 is extracted out, and easily cause lead coupling spring lamination 201 to be subjected to the strength of upwards pullling and be out of shape; So,, often be not suitable for being applied in and must plug circuit-board card 30 to carry out the test motherboard of test jobs though the electric connector structure of commonly seeing enough provides general motherboard to use.
The utility model content
The purpose of this utility model is will solve the electric connector of commonly seeing to be not suitable for being used in test with the problem on the motherboard, and a kind of clamp type electric connector that overcomes above-mentioned shortcoming is provided.
The utility model is made up of an electrical connector body and plural terminals, it is characterized in that electrical connector body is rectangular pedestal, be provided with a slot in the pedestal upper end, be provided with the terminal groove that a plurality of intervals are provided with in the two side of this slot, each terminal groove communicates with slot; Terminal has a terminal body portion, and bending inwards in terminal body portion upper end is provided with a lead coupling spring lamination, and lateral buckling convexes with one by pressure section in terminal body subordinate holds; Plural terminals plants the terminal groove in electrical connector body respectively, being stretched at the bottom of the slot of electrical connector body of each terminal by pressure section, but each terminal assembling is and presses down by the pressure section swing state.
Described terminal lower end is provided with can externally make the external electric structure that electrically connects.
Described lead coupling spring lamination is＜the shape lead coupling spring lamination.
The utility model makes terminal be movable shape and plants in the terminal groove of electrical connector body, at the bottom of making it be stretched on slot by pressure section, when a circuit-board card inserts, but the mat circuit-board card presses down and is made the inside clamping of lead coupling spring lamination/contact at circuit board clamp tip node by pressure section, reduce the amount of being compressed of lead coupling spring lamination, and prevent to bear the frictional force that circuit-board card is upwards chosen, to promote the useful life of whole electric connector.

Embodiment
See also Fig. 1, shown in Figure 2, the utility model is made up of an electrical connector body 1 and plural terminals 2, wherein, electrical connector body 1 is the rectangular pedestal of insulating matter, centre is provided with a slot 11 in the pedestal upper end, be provided with the terminal groove 13 that a plurality of intervals are provided with in the two side 12 of this slot 11, each terminal groove 13 communicates with slot 11.
See also Fig. 2, shown in Figure 3, the electrically conductive, electrically sub-element that terminal 2 constitutes for the sheet metal punching press, terminal 2 has a upright terminal body portion 21, bend inwards in terminal body portion 21 upper ends and to be provided with one＜shape lead coupling spring lamination 22, lateral buckling convexes with one by pressure section 23 in terminal body portion 21 lower ends, and terminal 2 lower ends are provided with can externally make the external electric structure 24 that electrically connects.
See also shown in Figure 2, make plural terminals 2 plant respectively in the terminal groove 13 of electrical connector body 1, make 11 ends of slot that are stretched on electrical connector body 1 by pressure section 23 of each terminal 2, but and make 2 assemblings of each terminal be pressing down by pressure section 23 swing states, make＜shape lead coupling spring lamination 22 front ends protrude in the slot 11, form the clamp type electric connector by this.
The utility model can utilize external electric structure 24 to be connected in general motherboard or test motherboard, by this when a circuit-board card 30 plugs, see also shown in Figure 4, can utilize the strength of this circuit-board card 30 press down each terminal 2 by pressure section 23, make each terminal 2 swing by this towards slot 11 directions, but make its epimere front end＜shape lead coupling spring lamination 22 clampings/the contact at plate tip node 301 of circuit-board card 30, so, can utilize the utility model that circuit-board card 30 is formed with motherboard with general motherboard or test electrically connects.
Because terminal 2 of the present utility model is when circuit-board card 30 inserts, just order＜shape lead coupling spring lamination 22 starts clamping/conflict, therefore can reduce＜amount of being compressed of shape lead coupling spring lamination 22 when circuit-board card 30 inserts, to prevent that plugging circuit-board card 30 repeatedly causes elastic fatigue or fracture; And each terminal 2 can utilize modes such as self gravitation and outwards arrange when circuit-board card 30 is extracted, make＜22 disengagings of shape lead coupling spring lamination, prevent＜shape lead coupling spring lamination 22 bears the pulling force that circuit-board card 30 makes progress, this shows, the utility model can reduce the damage factor of terminal 2, effectively promotes the useful life of whole electric connector and motherboard.
