Abstract
The utility model relates to a card edge connector used to cooperate with an expansion card. The card edge connector comprises an insulated body and conducting terminals. The insulated body has a slot used to accommodate the expansion card, and both sides of the slot are provided with a plurality of terminal accommodating holes. The terminal accommodating holes comprise buckling grooves that cooperate with the conducting terminals, and retreating spaces allowing conducting terminals to retreat. The transverse dimension of the retreating spaces is smaller than that of the buckling grooves. Compared to the prior art, the arrangement of the retreating spaces allows the conducting terminals to have more space for deformation, ensures the good flexibility of the conducting terminals, reinforces the strength of the insulated body with the dimension of the retreating spaces smaller than that of the buckling grooves, and ensures a longer service life of the card edge connector.
Description
[technical field]
The utility model relates to a kind of bayonet connector.
[background technology]
Expansion board is a kind of circuit board arrangement, promptly is provided with the electronic component that can produce above-mentioned corresponding function on circuit board, constitutes by corresponding circuit on a bayonet connector and the motherboard to electrically connect.Existing bayonet connector as shown in Figure 5, can electrically connect mutually with expansion board (not shown), and it comprises insulation shell 20, offers a central slot 22 to accommodate expansion board, and described central slot both sides are provided with terminal channel side by side; Signal terminal 21 can be housed in the corresponding terminal channel; When described expansion board inserted, the contact site 210 of signal terminal 21 can produce strain, to provide Elastic Contact described expansion board, realizes the electric connection of described expansion board and circuit board (not icon).Yet, in use, because the less contact site that makes in space of contact site distortion does not have enough elasticity, and expansion board owing to repeatedly peg graft, and contact site elastic fatigue can occur after through strain repeatedly, and the elasticity of contact site is diminished, cause expansion board and the loose contact that blocks insulated connectors, influence the normal electric connection of expansion board and circuit board.
Therefore, be necessary to design a kind of novel bayonet connector, to overcome above-mentioned defective.
[summary of the invention]
The purpose of this utility model is to provide a kind of novel bayonet connector, and it can guarantee that conducting terminal has elasticity preferably all the time, realizes the normal electric connection of expansion board and circuit board.
In order to reach above-mentioned creation purpose, the utility model bayonet connector, in order to match with expansion board, comprise insulating body and conducting terminal, insulating body is provided with a slot of accommodating expansion board, and the slot both sides are provided with the plurality of terminals accepting hole, and this terminal accommodation holes comprises and can and can allow bit space for what conducting terminal was stepped down with the support slot of conducting terminal interference engagement, wherein, the described lateral dimension that allows bit space is less than the lateral dimension of support slot.
Compared with prior art, the utility model bayonet connector, owing to allow the setting of bit space, make conducting terminal that more deformation space be arranged, better elasticity can be provided, guaranteed that conducting terminal has elasticity preferably all the time, can realize the normal electric connection of expansion board and circuit board, and owing to allow the size of bit space less than the size of support slot, but the intensity of heavy insulation body has guaranteed that bayonet connector has longer useful life.

[embodiment]
Below in conjunction with the drawings and specific embodiments the utility model bayonet connector is described further.
As shown in Figures 1 to 4, the utility model bayonet connector 1, in order to and expansion board (not shown) (in this example for PCI-EXPRESS card) match, include insulating body 10 and conducting terminal 11.
Insulating body 10 slightly is longitudinal, insulating body 10 is provided with a slot 100 of accommodating expansion board, slot 100 both sides are provided with plurality of terminals accepting hole 101, slot 100 forms with terminal accommodation holes 101 and is communicated with, this terminal accommodation holes 101 comprises and can and can allow bit space 1011 for what conducting terminal 11 was stepped down with the support slot 1010 of conducting terminal 11 interference engagement, wherein, the described lateral dimension that allows bit space 1011 is less than the lateral dimension of support slot 1010, but the intensity of heavy insulation body 10, the useful life of extending this bayonet connector.In addition, this terminal accommodation holes 101 also comprises the receiving space 1012 that can accommodate conducting terminal 11, and the described lateral dimension of bit space 1011 that allows is identical with the lateral dimension of receiving space 1012, and work in-process helps the manufacturing of mould like this, has saved production cost.
Conducting terminal 11 is contained in the above-mentioned terminal accommodation holes 101, described conducting terminal 11 comprises holding parts 110 and is extended upward the connecting portion 111 of bending by holding parts 110, by the connecting portion 111 downward contact sites 113 that extend, and by the contact site 113 downward support divisions 112 that are positioned at conducting terminal 11 ends that extend, and by the holding parts 110 downward weld parts 114 that extend.Described conducting terminal 11 is provided with at least two inflection points (for being provided with two A and B, also can be set to a plurality of certainly in the present embodiment) at connecting portion 111 places, the elasticity of this conducting terminal 11 can be provided.In addition, described insulating body 10 is provided with the block 102 that can supply support division to support, and the bottom of block 102 is provided with lead angle, and the setting of this lead angle can be beneficial to conducting terminal and insert in the insulating body.And the weld part 114 of described adjacent conductive terminal 11 staggers on longitudinally mutually, when described expansion board inserts this bayonet connector 1, described contact site 113 meeting compressive deformations, simultaneously strain also can take place and be housed in described allowing in the bit space 1011 in described connecting portion 111, so just increased the deformation space of conducting terminal 11, expansion board can closely be contacted with bayonet connector 1, realize its electric connection.
The utility model bayonet connector, owing to allow the setting of bit space, make conducting terminal that more deformation space be arranged, better elasticity can be provided, guaranteed that expansion board contacts with the tight of bayonet connector, can realize the normal electric connection of expansion board and circuit board, and owing to allow the size of bit space less than the size of support slot, but the intensity of heavy insulation body has guaranteed that bayonet connector has longer useful life.
