Description
The utility model relates to a kind of member of expansion slot connector of the circuit board (interface panel) that is used to peg graft, i.e. bonder terminal.
Existing expansion slot connector is assembled by glue shell and terminal, and its terminal protruding point left-right symmetric realizes the function of clamping interface card (be interface panel, or circuit board) on sustained height; When circuit board is not put into the expansion slot connector as yet, because the distance between the terminal projecting point is very little, very easily cause short circuit if any terminal distortion or improper use or when foreign material are arranged, and existing terminal in use for some time, all can cause loose contact because of elastic fatigue.Also because the terminal of expansion slot is very many usually, described loose contact causes very big difficulty when maintenance circuit, and because of being difficult to determine to have produced tired terminal, even determined, minimum because of terminal, one has terminal is ruptured during maintenance.
(this figure is existing expansion slot sectional structure) as shown in Figure 1, tradition expansion slot terminal produces the elastic force part and protrudes below, position (1) between the crooked position (2) at its arc, and arc protrudes top, position (1) to all inelastic effect between the crooked position (3).So described terminal very easily produces elastic fatigue and causes loose contact, or because of the not good substandard products that manufacture process occurs of its elastic force.
The purpose of this utility model is, a kind of improved expansion slot bonder terminal is provided, and has better elasticity, can realize the connection that patches of circuit board reliably, and it is rational in infrastructure, long service life.
The technical solution of the utility model is, described terminal has the top, these both sides, top have respectively that its lower end is the arc lordosis of turning circuit in order to the contact circuit plate in order to be held in the convex shoulder in the expansion slot, the lower end of described arc lordosis is the middle part that has in order to the hole, garden that increases terminal elastic force, there is caudal leg lower end partly, this centre, its design feature is, described terminal is provided with respect to the auxiliary shell fragment of convex behind the arc of arc lordosis, and an end of described auxiliary shell fragment is connected an end position place of arc lordosis and the other end is a free end.
Make below in conjunction with drawings and Examples and to further specify.
Description of drawings: Fig. 1 is a prior art expansion slot sectional structure, and Fig. 2 and Fig. 7 are respectively the expansion slot sectional structure of the utility model terminal, and Fig. 3 to Fig. 6 and Fig. 8, Fig. 9 are different example structure.In the drawings:
The 1-arc protrudes the position, and 2, the 3-crooked position,
11-arc lordosis, the 12-top,
The 13-crooked position, the auxiliary shell fragment of convex behind the 14-arc,
15-expands cell body, the 16-caudal leg,
Part in the middle of the 17-, hole, 18-garden,
The 19-groove, 20-convex shoulder, 60-card post.
By accompanying drawing as can be known, terminal of the present utility model (10) has top (12), both sides, this top (12) have respectively that its lower end is the arc lordosis (11) of turning circuit in order to the contact circuit plate in order to be held in the convex shoulder (20) in the expansion slot, the lower end of described arc lordosis (11) is middle partly (17) that have in order to the hole, two gardens (18) that increases terminal (10) elastic force, this centre partly (17) lower end is caudal leg (16), its design feature is, described terminal (10) is provided with respect to the auxiliary shell fragment (14) of convex behind the arc of arc lordosis (11), and an end of this auxiliary shell fragment (14) is connected an end position place of arc lordosis (11) and the other end is a free end.
The terminal of the above-mentioned improvement structure of the utility model has better overall elastic force, connecting circuit plate and guarantee circuit turn-on reliably, and not fragile or short circuit has improved product quality effectively, has prolonged product useful life.
Fig. 3 is a kind of embodiment of the present utility model.As shown in Figure 3, the arc lordosis (10) of above-mentioned terminal middle part is provided with groove (19), and its auxiliary shell fragment (14) upper end is connected described arc lordosis (11) position, upper end and the other end of this shell fragment (14) is a free end.In fact, it by groove (19) position backward punching out come out to form, its auxiliary shell fragment (14) makes whole terminal all have elastic force in order to prop up expansion slot storage tank rear wall shown in Figure 2, increases its chucking power to circuit board thus.
Fig. 4 is another kind of example structure, it is connected the place, position, bottom of arc lordosis (11) with the different lower ends of described auxiliary shell fragment (14) that are of structure shown in Figure 3, and its free end touches and is against on the top (12), makes terminal have better elastic force thus.
Fig. 5 is another kind of example structure.Its auxiliary shell fragment (14) is to lay respectively at two of arc lordosis (11) both sides, and connects the position, upper end of described arc lordosis (11) on it.This structure is easy to make.
Fig. 6 is that other plants example structure.Its auxiliary shell fragment (14) is also for laying respectively at two of arc lordosis (11) both sides, and the lower end of auxiliary shell fragment (14) connects place, arc lordosis (11) position, bottom and its upper end (free end) is touched and is against on the top (12).
Fig. 8 is another example structure.There is groove (19) at described arc lordosis (11) middle part, and the upper end of auxiliary shell fragment (14) is connected arc lordosis (11) position, upper end and its free end is the straight shaped end head.This structure when reality is used, need in expansion slot, to be provided with one as shown in Figure 7 in order to block the card post (60) of described straight shaped end head, this moment, terminal integral body all produced elastic force, also can make its with the auxiliary shell fragment of relative terminal between unlikely short circuit.
Example structure shown in Figure 9 is, described auxiliary shell fragment (14) is for being positioned at two of arc lordosis (11) both sides, and its upper end is connected arc lordosis (11) position, upper end, and its free end (lower end) is the straight shaped end head.
