Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
A kind of embodiment: multi-channel radio frequency connector
Referring to attached drawing 1-4, including the connector male head 1 and connector female end 2 being mutually inserted, the connector male head 1 is wrapped
Male housing 10 is included, a first grafting channel 11 plugged for the female housing 20, institute are equipped with inside the male housing 10
The inner wall for stating the first grafting channel 11 is equipped with a lug boss 15, is equipped with outside two groups and leads in the space in first grafting channel 11
Body is equipped with a contact pin 14 in every group of outer conductor.
The connector female end 2 includes female housing 20, and the outer wall of the female housing 20 is equipped with a recessed portion 23, institute
It states and is equipped with two groups of second grafting channels 21 plugged for the outer conductor, the sky in every group of second grafting channel 21 in female housing 20
It is interior to be equipped with a jack 22 corresponding with the contact pin 14.
Wherein, first grafting channel 11 and peripheral shape, the size of female housing 20 match, second grafting
Channel 21 and peripheral shape, the size of outer conductor match.Referring to attached drawing 2 and 4,23 shape of the lug boss 15 and recessed portion,
Size matches, and corresponds in connector male head 1 and connector female end 2, one on the inner wall in the first grafting channel 11 inside
Portion is equipped with a smooth lug boss 15, i.e., clips a smooth small semicircle on the inner wall by the first grafting channel 11, another one exists
The outer wall of corresponding female housing 20 is equipped with a smooth recessed portion 23, i.e., equally clips one on the outer wall by female housing 20
Smooth small semicircle when grafting, passes through lug boss 15 and recessed portion 23 positions.
In the present embodiment, using two groups of outer conductors and corresponding two the second grafting channels 21, corresponding two groups of 14 Hes of contact pin
Jack 22, i.e. the present embodiment are two core connectors, in fact, can also be 3 cores, 4 cores, 5 cores, 6 cores etc. array core connector,
It is not limited only to the core number of the present embodiment.
The outer conductor is fluting elastic piece structure, which includes several along the circumferentially-spaced cloth in 14 periphery of contact pin
The elastic slice 12 set.The free end area of fluting elastic piece structure is corresponding circumferentially arranged with a bulge loop 13 in the Male head connector 1
An annular groove 24 being caught in for the bulge loop 13 is equipped in female connector 2 in second grafting channel 21.
In the plugged state, the female housing 20 is inserted into the first grafting channel 11 of male housing 10, passes through male connector
The lug boss 15 of shell 10 is matched with the recessed portion 23 of female housing 20, and the connector in grafting channel can quickly be made to be aligned,
Wrong plug position is avoided, i.e., so that outer conductor is inserted into the second grafting channel 21 of the female housing 20, at this point, in the outer conductor
Contact pin 14 be inserted into the second grafting channel 21 jack 22, it is described fluting 12 structure of elastic slice slide into female housing 20 the second grafting
It in channel 21, is caught in annular groove 24 and is engaged by bulge loop 13, the connector male head 1 and connector female end 2 are realized with this
Coaxially connected locking.
The working principle of the multi-channel radio frequency connector of the present embodiment: the course of work is roughly divided into two states, i.e., self-locking
State and unlocked state.
(1) self-locking state, when connector female end 2 be inserted into connector male head 1 the first grafting channel 11 when, due to first insert
The outer conductor connected in road 11 is made of multiple elastic slices 12, when pushing connector female end 2 to be inserted into connector male head 1, passes through company
The recessed portion 23 for connecing 2 periphery of the lug boss 15 of 11 inner wall of the first grafting channel and connector female end in device male connector 1 positions, and first inserts
The elastic slice 12 for connecting the outer conductor in road 11 slides into the second grafting channel 21 of female housing 20, until the elastic slice 12 of outer conductor
It is engaged in the annular groove 24 that the bulge loop 13 of outer surface is caught in the second grafting channel 21, realizes self-locking state, at this point, just,
Two contact pins 14 are just inserted into two jacks 22 in the second grafting channel 21 in the outer conductor of connector male head 1, real as a result,
The quick grafting of existing connector male head 1 and connector female end 2.
Due to the shape of 20 periphery of female shell of the lug boss 15 and connector female end 2 of 11 inner wall of the first grafting channel,
Size and structure matching, through the cooperation of lug boss and recessed portion, when grafting, it is easy to by the female of connector female end 2
Shell 20 is inserted into the first grafting channel 11 of connector male head 1, and the contact pin 14 in connector male head 1 is also at this moment inserted into connection
In second grafting channel 21 of device female 2, avoid that there is a phenomenon where wrong plugs.
(2) unlocked state is in connector male head 1 with hand by 1 drawing outward of opposing connector female 2 of connector male head
The outer conductor stress of fluting elastic piece structure deforms inwardly, at this point, just skidded off from the annular groove 24 of connector female end 2, from
And connector male head 1 and connector female end 2 are separated.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
