Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig.1, a kind of easy-to-dismount AC/DC power modules are provided in the utility model embodiment, feature exists
In, including socket 100 and the inserted block 200 that is plugged on the socket 100, the socket offer multiple jacks on 100 top surface
120, be respectively and fixedly provided with a contact pin 110 in each jack 120, the contact pin 110 from the bottom surface of the socket 100 stretch out with
Grafting on circuit boards, has and 120 one-to-one pin 210 of jack on the socket 100 on 200 bottom surface of the inserted block.
The power module that the inserted block 200 as uses usually is plugged in the form of integration module on the socket 100.
With reference to Fig. 2 and Fig. 3,100 inside of the socket is lock slots 140, and locking device is equipped in the lock slots 140
130, the locking device 130 includes briquetting 131, strut 132 and connecting rod 150, and 131 one end of the briquetting passes through described
The side wall of lock slots 140 exposes outside the socket 100, and the other end is fixedly connected with two struts 132, two branch
132 length of bar is identical and is arranged in parallel, two struts 132 back to side on close to one end of the briquetting 131
Be vertically and fixedly provided with left compression bar 133, back to side on one end far from the briquetting 131 be vertically and fixedly provided with right compression bar
134, the left compression bar 133 and right compression bar 134 are l-shaped rod, and l-shaped rod two parts junction has inclined-plane.
The quantity of the connecting rod 150 is two, is separately mounted to 140 inside of the lock slots close to two rows of jacks
On 120 side, 150 both ends of the connecting rod all have briquetting 151, and the end of the briquetting 151 is and the left compression bar 133
With the matched inclined-plane of 134 ramp of right compression bar, two briquettings 151 are supported by inclined-plane in a strut respectively
On the left compression bar 133 of 132 homonymies and the inclined-plane of right compression bar 134, the left compression bar 133 and right compression bar 134 is made to be parallel to
When being moved on the direction of the connecting rod 150, the briquetting 151 can be moved on the direction of the connecting rod 150.
The connecting rod 150 is equidistant on the side between two briquettings 151 to be fixed with multiple inserted links 152, often
The side wall that a inserted link 152 both passes through the lock slots 140 is inserted into a jack 120, and the connecting rod 150 is also logical
Multiple springs 160 are crossed to be connected on the side wall that the inserted link 152 passes through.The spring in stable state of the connecting rod 150
160 provide pulling force, so that the briquetting 151 is tightly attached on the inclined-plane of the left compression bar 133 and right compression bar 134.
In order to not influence the signal transmission of contact pin 110 in the jack 120, the connecting rod 150, briquetting 151 and inserted link
152 are integrally formed, and make to be made from an insulative material.Certain inserted link 152 can be metal material, but the connecting rod
150 be isolation material, and the inserted link 152 is bonded in the connecting rod 150.
The connective stability of the pin 210 of the inserted block 200 and contact pin 110 in the jack 120 in order to further increase,
A card slot can also be opened up respectively on the opposite side of two rows of pins 210, when the pin 210 is inserted into the jack
After 120, the inserted link 152 is inserted into the card slot and supports pin 210 on the contact pin 110.
When needing to dismantle the inserted block in the power module, the briquetting, the left compression bar and right compression bar are pressed inward against
The direction that strut is parallel in the drive lower edge of strut is moved, since the briquetting supports on the inclined-plane of left compression bar and right compression bar
On, therefore the briquetting is along perpendicular to side wall of the direction of strut far from the lock slots, and then drives the inserted link from described
It is extracted out in jack, the pin disengaging and the contact of the contact pin of the inserted block, can easily take out inserted block at this time.It changes
After new inserted block, the briquetting is unclamped, the connecting rod is close perpendicular to the direction of strut in the pulling force effect lower edge of spring
The side wall of lock slots, therefore inserted link is inserted into jack, the pin of inserted block is held out against to be electrically connected with contact pin, while with briquetting
The mobile left compression bar and right compression bar are moved along the direction for being parallel to strut, and the briquetting is made to stretch out again, are returned back to initial
State.
In conclusion the easy-to-dismount AC/DC power modules that the utility model embodiment provides, including socket and grafting
Inserted block on the socket offers multiple jacks on socket top surface, has on inserted block bottom surface and jack on socket one is a pair of
The pin answered, pin are electrically connected after being inserted into jack with the contact pin in jack, are lock slots inside socket, lock is equipped in lock slots
Determine device, locking device includes the inserted link for being inserted into jack, and after the briquetting for pressure-locking device, inserted link is extracted out from jack, can
Very easily to take out inserted block, release briquetting can be such that inserted link is reinserted into jack after changing new inserted block, and inserted link will be inserted
The pin of block is held out against to be connect with contact pin.The power module of the utility model locks the pin of inserted block using locking device
Fixed, there is no frictions in swapping process, therefore slow down the abrasion of contact pin significantly, while the mode that inserted link is held out against also makes pin
Electrical connection between contact pin is more reliable and more stable.
Disclosed above is only several specific embodiments of the utility model, and still, the utility model embodiment is not office
It is limited to this, the changes that any person skilled in the art can think of should all fall into the scope of protection of the utility model.
