Specific embodiment
Below in conjunction with attached drawing, pass through the description to the preferred embodiment of the present invention, more clearly and completely elaboration
The technical solution of invention.
As shown in Figure 1 to Figure 3, the radio frequency elasticity needle connector of the preferred embodiment of the present invention include the first inner conductor 11,
Second inner conductor 12, third inner conductor 13, insulator 2, spring 3.First inner conductor 11 is connect with the second inner conductor 12, in second
One end of conductor 12 and one end of third inner conductor 13 are socketed, and insulator 2 is sleeved on third inner conductor 13, spring 3 from first
Inside inner conductor 11 internal stretch to third inner conductor 13.
Specifically, the first inner conductor 11 is a cover shape, internal that the first blind hole 110 is arranged, the first blind hole 110
Opening direction the second inner conductor 12 of direction.The blind hole open end of first inner conductor 11 and the second inner conductor 12 are interference fitted, thus
The two is fixedly connected.
A second inner conductor 12 substantially hollow cylinder, it is internal that there is through-hole 120.Second inner conductor 12 is separate
One end of first inner conductor 11, namely the one end being socketed with third inner conductor 13, are provided with multiple profile grooves 121, and profile groove 121 is along the
The longitudinal of two inner conductors 12 extends, and the end of the second inner conductor 12 forms choke 122 to contract.Second inner conductor 12
By dotting process, make to form multiple recess on its outer wall, be recessed prominent towards the inside of the second inner conductor 12, constitutes limit knot
Structure 123.
Preferably, the second inner conductor 12 is made of sprung copper, such as beryllium copper, phosphor-copper etc., is machined or is used by tubing
Board mould carries out enclosing round forming, and processing technology is simpler.
Third inner conductor 13 passes through insulator 2, and both ends are stretched out from insulator 2.Third inner conductor 13 is matched by interference
It closes or encapsulated mode is fixedly connected with insulator 2.Third inner conductor 13 is equipped with third close to one end of the second inner conductor 12
Blind hole 130, opening direction the second inner conductor 12 of direction.In the assembled condition, the first blind hole 110, through-hole 120, third blind hole
130 collectively form one for accommodating the chamber of spring 3.
The one circle groove 133 of one end setting of third inner conductor 13 and the socket of the second inner conductor 12, the groove 133 apart from this
There is certain distance in the socket end end face of three conductors 13, therefore, on the longitudinal direction of third conductor 13, the both ends of groove 133 and third
The shaft shoulder is formed between the outer circumference surface of conductor 13, two shaft shoulders respectively constitute the first limiting section 131 and the second limiting section 132.
The inside of insulator 2 is equipped with stepped hole, including the first hole portion 21 and the second hole portion 22, the second hole portion 22 are led with third
Body 13 cooperates, and the internal diameter of the first hole portion 21 is greater than the second hole portion 22, and it is located at close to one end of the second inner conductor 12, is used for
Accommodate the choke 122 of the second inner conductor 12.
Preferably, insulator 2 is machined using Teflon (PTFE), or with other plastic cement (such as LCP) molds.
In the assembled condition, one end of the first inner conductor 11 and the second inner conductor 12 is interference fitted, the second inner conductor 12
The other end is socketed on third inner conductor 13, and internal diameter is slightly larger than the outer diameter of third inner conductor 13, the limit of the second inner conductor 12
Structure 123 is located in the groove 133 of third inner conductor 13, but the not circumference contact with groove 133 of position limiting structure 123,
I.e. there are certain distance between position limiting structure 123 and the periphery of groove 133, the benefit designed in this way is: when the second conductor 12
When sliding relative to third conductor 13, position limiting structure 123 vacantly moves axially in groove 133, does not contact between the two, from
And reduce frictional force.The choke 122 of second conductor 12 extends at least partially into the first hole portion 21 of insulator 2, and with
The outer circumference surface of third inner conductor 13 contacts.One end of spring 3 is contacted with the bottom hole of the first blind hole 110, and the other end is blind with third
The bottom hole in hole 130 contacts.
When external force is when on the first inner conductor 11,11 compressed spring 3 of the first inner conductor, and push the second inner conductor 12
Towards the direction axial displacement of insulator 2, choke 122 slides on the excircle of third inner conductor 13, and choke 122 is set
Meter is so that the second inner conductor 12 and third inner conductor 13 remain contact, to ensure that good signal transmission.Limit knot
The axial displacement in groove 133 of structure 123, when it moves to the second limiting section 132, the blocking by the second limiting section 132 is not
It is displaced again, this is the extreme position that connector is shunk.
When the external force acted on the first inner conductor 11 is eliminated, under the elastic force effect of spring 3,11 He of the first inner conductor
Direction axial displacement of second inner conductor 12 away from insulator 2, the opposite direction displacement in groove 133 of position limiting structure 123, when
When it moves to the first limiting section 131, the blocking by the first limiting section 131 is no longer displaced, this is the limit of connector pop-up
Position.
The present invention is by part (the i.e. choke 122 and third conductor 13 of the position limiting structure between inner conductor and sliding contact
Outer circumference surface) it is independent separate so that Each performs its own functions for two parts, be independent of each other, the unrestricted position of the frictional force for the part that is in contact
The influence of structure, thus be able to achieve lesser frictional force and preferable contact, in frictional force and contact, the two are contradictory
Reach an optimal effect between factor.
Only preferred embodiments of the present invention will be described for above-mentioned specific embodiment, and not to guarantor of the invention
Shield range is defined.Under the premise of not departing from design concept of the present invention and scope, those skilled in the art
Provided verbal description, attached drawing various modifications to made by technical solution of the present invention, substitution and improvement according to the present invention,
It should belong to protection category of the invention.Protection scope of the present invention is determined by claim.
