Description

Floating joint structure

Technical Field

The present invention relates to a connector structure, and more particularly, to a floating connector structure for connecting a center contact pin of a coaxial connector.

Background

Coaxial cable connectors, such as F-connectors, are used to connect a coaxial cable to another object, such as an appliance or a fitting, having terminals adapted to engage the connector. For example, F-connectors are often used to terminate drop cables in cable television systems. Coaxial cables typically include an inner conductor surrounded by a dielectric layer, which in turn is surrounded by a conductive grounding foil and/or braid defining an outer conductive grounding sheath. The outer conductive ground sheath itself is surrounded by a protective outer jacket. The F-connector is typically secured to the prepared end of the jacketed coaxial cable, thereby allowing the coaxial cable end to be connected to a junction box, such as by a threaded connection with a threaded terminal of the junction box.

Communication devices (also known as telecommunications equipment or communication equipment) are hardware used for telecommunications applications. With the growth of the internet, the application of telecommunication data transmission is becoming more and more extensive, and the variety of communication devices is also increasing, such as: switch, modem, router. Because of the large amount of signals transmitted and received by the communication device, a plurality of plate-type radio frequency units on the circuit board must transmit and receive signals in the same frequency band respectively to be converged, thereby being capable of improving the transmission quantity of the frequency band by times. However, the plate-type radio frequency unit is an electronic component of the circuit board, and has a small size and poor signal. Therefore, an external transmission member (i.e., a coaxial cable or an antenna) is externally connected through a coaxial connector to strengthen the signal. The types of coaxial connectors are numerous, such as SMA, TMC, NTYPE, etc.

However, when the metal pin of the coaxial cable connector is connected to the connector, there are problems that the metal pin is easily broken or the metal pin is shifted up and down and left and right.

Referring to fig. 1A to 5, fig. 1A is an appearance schematic diagram of a floating joint structure according to the present invention. Fig. 1B is an external view of the floating joint structure and the coaxial connector of the present invention. Fig. 2 is an exploded schematic view of the floating joint structure of the present invention. FIG. 3 is a schematic diagram of the floating joint configuration of the present invention viewed from the side in the X-axis direction. FIG. 4 is a schematic view in side elevation of the Y-axis of the floating joint configuration of the present invention. FIG. 5 is a schematic view of the floating joint structure of the present invention connected to the center contact pin of a coaxial connector. Referring to fig. 1A, in the embodiment of the utility model, the floating connector structure 100 is particularly used for connecting a center contact pin 201 of a coaxial connector 200, and the center contact pin 201 is made of metal material and has good electrical characteristics. In the present embodiment, the center contact pin 201 is a metal pin (metal pin; center conductor), but not limited thereto. The floating joint structure 100 includes a two-axis buffer balance metal member 110, a movable buffer main body 120, an insulating body 130 and a housing 140. Regarding the two-axis buffering balance metal element 110, the two-axis buffering balance metal element 110 is an integrally formed structure, two sides of the X-axis of the two-axis buffering balance metal element 110 are respectively provided with a first n-shaped structure 111 and a second n-shaped structure 112, two sides of the center of the two-axis buffering balance metal element 110 are respectively provided with a first clamping structure 113 and a second clamping structure 114 of the Y-axis, and one end of each of the two clamping structures is a top curved

inclined surface

113A and 114A, wherein the first n-shaped structure 111 and the second n-shaped structure 112 are connected to a center TC of the two-axis buffering balance metal element 110. In addition, the first n-shaped structure 111 and the second n-shaped structure 112 are elastic cantilevers, and the bending direction is a copper plate rolling direction. Moreover, a first concave structure 115 is arranged between the first n-shaped structure 111 and the center TC, a second concave structure 116 is arranged between the second n-shaped structure 112 and the center TC, and the first concave structure 115 and the second concave structure 116 are elastic structures, so that the two-axis buffer balance metal piece 110 can buffer stress interference in the X-axis direction, thereby avoiding too large offset of the metal needle and avoiding axis dislocation.

Next, in further detail, in the embodiment of the utility model, regarding the movable buffering body 120, the movable buffering body 120 has an accommodating space 121 inside, two sides of the top of the accommodating space 121 are two guiding inclined surfaces 1211 and the other two sides of the top are two grooves 1222, and the two grooves 1222 of the movable buffering body 120 are engaged with the top curved

inclined surfaces

113A and 114A of the first engaging structure 113 and the second engaging structure 114, wherein a circular outer wall 1223 is formed around the middle of the accommodating space 121. In addition, when the two grooves 1222 of the movable buffer body 120 are engaged with the top

curved slopes

113A and 114A of the first engaging structure 113 and the second engaging structure 114, the surfaces thereof are combined with the two guiding slopes 1211 to form a complete circular slope, as shown in fig. 2 to 4. Furthermore, the first engaging structure 113 and the second engaging structure 114 respectively have abutting

pieces

1131 and 1141 for abutting against the movable buffer main body 121 in a forward direction, and the movable buffer main body 120 is movable to buffer the stress interference in the Y-axis direction, so as to avoid the over-large offset of the metal pins and the misalignment of the shafts.

Regarding the insulating body 130, the insulating body 130 is disposed outside the two-axis buffer balance metal 110 and the movable buffer main body 120, an inner space of the insulating body 130 is hollow, and the movable buffer main body 120 is disposed in the inner space. It should be noted that at least one end of the two-axis buffer balance metal element 110 extends to be connected to the outside of the insulating body 130, and specifically, one end (the end away from the center TC) of the first n-shaped structure 111 extends to a part of the structure to the outside of the insulating body 130. Regarding the housing 140, two sides of the housing 140 respectively have a first elastic supporting member 141 and a second elastic supporting member 142 for supporting the external structure of the coaxial connector 200, as shown in fig. 5, and the housing 140 is disposed outside the insulating body 130, which can provide a good shielding effect. As shown in fig. 5, for example, a conventional coaxial connector 200 with a floating mechanism includes, in a separate manner: the movable part of the base body is connected with the opposite side coaxial connector; and a connector base for movably holding the holder body fixing portion. Accordingly, the overall external shape of the coaxial connector 200 becomes large, which is a problem of being disadvantageous in terms of downsizing. Further, in the conventional coaxial connector with a floating mechanism, a coil spring or a disc spring for urging the movable portion of the housing in the axial or radial direction is required, and accordingly, the number of parts increases, which causes a problem of an increase in manufacturing cost and manufacturing process. Further, in the conventional coaxial connector with floating mechanism 200, the center contact of the movable portion of the housing and the center conductor of the connector base are formed separately, and the connector body is movable in the axial direction and the radial direction with respect to the movable portion of the housing, so that a structure for electrically connecting the center contact and the center conductor to each other in a movable manner is required, which causes a problem of complicated structure. High frequency performance is important in the coaxial connector 200, and the coaxial connector 200 having the floating mechanism has the following disadvantages: when the center conductor moves together with the socket main body (floating joint structure 100) and axial misalignment occurs between the center conductor and the center conductor of the socket base, high-frequency performance is degraded. In the embodiment of the present invention, the first elastic supporting element 141 and the second elastic supporting element 142 are mainly used to support and support the coaxial connector 200 against their elastic capabilities and structures, as can be clearly understood from fig. 5.

Referring to fig. 6 to 8, fig. 6 is a schematic diagram illustrating an X-axis operation of the center contact pin of the coaxial connector connected by the floating joint structure of the present invention. FIG. 7 is a schematic view showing the Y-axis operation of the floating joint structure of the present invention in connection with the center contact pin of a coaxial connector. Fig. 8 is a cross-sectional view of fig. 7. The center contact pin 201 (i.e. the center contact) of the coaxial connector 200 is inserted between the first engaging structure 113 and the second engaging structure 114, and the first engaging structure 113 and the second engaging structure 114 are symmetrical to each other. When the center contact pin 201 is just inserted, if the guide inclined surface 1211 or the complete circular inclined surface of the movable buffer body 120 is contacted, the movable buffer body 120 is automatically compensated to move and correct the offset so that the center contact pin 201 can smoothly slide into and be inserted between the first engaging structure 113 and the second engaging structure 114. Then, after the center contact pin 201 is inserted, the two-axis buffer balance metal member 110 is pressed to deform and buffered by the first n-shaped structure 111 and the second n-shaped structure 112 in the X-axis direction to achieve balance and avoid axial misalignment, and on the other hand, after the center contact pin 201 is inserted, the two-axis buffer balance metal member 110 is pressed to deform and buffered by the first engaging structure 113 and the second engaging structure 114 in the Y-axis direction and the movable buffer main body 120 to achieve balance and avoid axial misalignment. The automatic offset compensation mechanism of the floating joint structure 100 of the present invention can avoid the problem of too large offset of the center contact pin 201 and avoid the problem of misalignment. It should be noted that, when the center contact pin 201 is separated from between the first engaging structure 113 and the second engaging structure 114, the two-axis buffering balance metal 100 is elastically restored, that is, the first n-shaped structure 111 and the second n-shaped structure (both being elastic structures) 112 at two sides of the X-axis are restored, and the first engaging structure 113 and the second engaging structure 114 in the Y-axis are also restored.

It should be noted that, in the above-mentioned embodiment, the floating joint structure 100 may be used for a multiple coaxial connector movably coupled to the two-axis buffer balance metal member 110, but the present invention is not limited to any type of coaxial connector.

Next, referring to fig. 9A and fig. 9B together, fig. 9A is a simulation diagram of S parameters of the floating joint structure connecting coaxial connector according to the present invention. Fig. 9B is a diagram of S-parameter simulation of a prior art lower-interface structure-connected coaxial connector. It can be seen from a comparison of the two S-parameter simulations that the present invention has significant improvement in both Frequency (Frequency) and GHz on the horizontal axis and intensity (Magnitude) and dB on the vertical axis. Comparing the coordinates a1, a2, A3, a4, a5 and a6 of fig. 9A and the coordinates B1, B2, B3, B4, B5 and B6 of fig. 9B, it can be known that the frequency of the present invention is 19 to 21dB at the frequency of 5G to 6G, which is much better than the prior art of 9 to 11dB, and the effect of the electrical characteristics exhibited at high frequency is far beyond the standard in the industry.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
