The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
Example 1
As shown in fig. 1, the embodiment of the invention provides a radio frequency connector connecting structure, which is characterized in that a replaceable clamping groove type fixing piece is added to the traditional radio frequency connector product technology, and is matched with a clamping groove on the outer wall surface of a connecting part of a radio frequency connector, so that the radio frequency connector and a connector shell can be connected more firmly, and the problem that the whole product is in poor contact or scrapped due to falling of welding pins when the connecting structure is stressed in the traditional technology is solved.
The radio frequency connector connection structure is used for connecting the radio frequency connector 100 and the connector housing 200 together, and comprises a clamping groove 11 formed on the outer wall surface of a connection part 1 of the radio frequency connector 100, a fixing piece 2 embedded in the clamping groove 11 and at least one clamping point 3 formed on the connector housing 200, wherein at least one clamping position 12 is formed on the connection part 1, and the at least one clamping point 3 and the at least one clamping position 12 are mutually clamped when the radio frequency connector 100 and the connector housing 200 are connected.
In this embodiment, the clamping groove 11 is circular and extends only approximately halfway into the connecting portion 1; it should be noted that the slot 11 may have many practical forms, but only provides the fixing piece 2 with a position where the locking is able to be connected.
Preferably, the fixing piece 2 is provided with a clamping part 21; the clamping portion 21 includes a clamping hole 211 and a guiding slot 212 in communication with the clamping hole 211, and the guiding slot 212 extends to the edge of the fixing piece 2.
In this embodiment, the clamping hole 211 is in a circular arc shape, the guiding groove 212 is in a rectangular shape, and the width of the guiding groove 212 is smaller than or equal to the diameter of the clamping hole 211.
Fig. 1 shows a case when the width of the guide groove 212 is smaller than the diameter of the catching hole 211, and fig. 2 shows a case when the width of the guide groove 212 is equal to the diameter of the catching hole 211. It should be noted that, in this embodiment, fig. 1 and 2 are different from each other in the shape of the fixing piece 2, and there are some differences due to the shape change of the fixing piece 2, but the overall connection structure is not greatly different.
Specifically, when the connection structure is used, the connection portion 1 of the rf connector 100 slides into the clamping hole 211 from the guide groove 212. Since the diameter of the connecting portion 1 is smaller than or equal to the diameter of the fastening hole 211, but larger than the width of the guide groove 212, the connecting portion 1 is deformed by the edge of the guide groove 212 in the guide groove 212, and when sliding into the fastening hole 211, the connecting portion 1 resumes the deformation, so that the fixing piece 2 is fixed in the fastening groove 11 of the connecting portion 1.
Preferably, the fixing piece 2 is formed with at least two clamping positions 22, and the at least two clamping positions 22 are symmetrically disposed on the left and right sides of the guiding slot 212.
The connector housing 200 is formed with protruding snap points 4 corresponding to at least two detents 22 on the securing tab 2.
In this embodiment, at least two through holes 23 are formed in the fixing piece 2, and a clamping position 22 is formed in each through hole 23. It should be understood that, for the locking portion 22, the through hole 23 is not necessarily formed, for example, a blind hole is formed inside, so long as the position where the protruding locking point 4 is locked can be provided, and it is preferable that the through hole 23 can be locked more firmly.
Preferably, the convex clamping point 4 is wedge-shaped and has an inclined surface. The fixing piece 2 passes through the bottom of the inclined plane and then passes through the top of the inclined plane in the process of being embedded into the clamping groove 11, and the fixing piece 2 can be easily clamped on the connector shell 200 by utilizing the convex clamping point 4 of the wedge-shaped structure.
In order to perform a certain length adjustment in practical use, at least two clamping grooves 11 are provided on the outer wall surface of the connecting portion 1 of the rf connector 100 at intervals along the length direction of the rf connector 100, and an operator may select any one of the clamping grooves 11 to set the fixing piece 2.
Wherein, the thickness of the fixing piece 2 is equal to the width of the clamping groove 11, and the material of the fixing piece 2 is elastic plastic.
Referring to fig. 3, in one embodiment, preferably, an end of the connecting portion 1 away from the fixing piece 2 is connected to a fixing platform 5, at least two clamping positions 51 are formed on the fixing platform 5, and a protruding clamping point 6 corresponding to the at least two clamping positions 51 on the fixing platform 5 is formed on the connector housing 200.
It should be noted that, the clamping position 51 on the fixing platform 5 and the clamping point 6 on the connector housing 200 are clamped with each other when the rf connector 100 and the connector housing 200 are connected, so as to improve the torsion requirement of the product. Of course, the fixing platform 5 may be formed with only one clamping position 51, but the effect of only forming one clamping position 51 on improving the torsion requirement of the product is not obvious; preferably, the number of the clamping positions 51 on the fixing platform 5 and the clamping points 6 on the connector housing 200 is three, and the specific setting positions are not limited.
In order to further improve the torque requirement of the product, as shown in fig. 4, a clamping point 7 corresponding to the clamping position 12 on the connecting portion 1 is formed on the inner side wall of the clamping hole 211 of the fixing piece 2; the guiding groove 212 of the fixing piece 2 is outwardly extended with a bendable pin 213. When the fixing piece 2 is fitted into the clamping groove 11 of the connecting portion 1, the bendable leg 213 is bent, so that the fixing piece 2 and the connector housing 200 can be assembled, and the fixing piece 2 is prevented from falling off.
According to the radio frequency connector connecting structure provided by the embodiment of the invention, the replaceable clamping groove type fixing piece is added on the traditional radio frequency connector product technology, and the radio frequency connector and the connector shell can be firmly connected by matching with the clamping groove of the outer wall surface of the connecting part of the radio frequency connector.
The above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
