Detailed Description
In the description of the present invention, it is to be understood that the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience of description of the present invention and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the following, the content of the present invention will be further described in detail with reference to the specific embodiments, and fig. 1 shows the installation schematic diagram of the Fakra connector and the fixing base of the present invention, it can be seen that the Fakra connector is usually detachably connected to the fixing base by means of a fastening member in the actual installation process, so as to achieve the reliable fixing of its own position.
Fig. 2, fig. 3, and fig. 4 respectively show a perspective view, a right side view, and a cross-sectional view a-a of the Fakra connector, and it can be seen that the Fakra connector mainly comprises an outer protective shell 1, an inner shielding shell 2, a plastic ferrule 3, and a metal terminal 4, wherein the metal terminal 4, the plastic ferrule 3, and the inner shielding shell 2 are coaxially sleeved and fixed from inside to outside in sequence, and are inserted into the outer protective shell 1 as a whole. It is important to note here that the protective outer shell 1 is preferably made of a metal having a good shielding function and a high structural strength. Therefore, on one hand, the shielding performance of the Fakra connector is further improved, so that signals are prevented from being interfered by an external magnetic field in the transmission process, and the transmission quality and stability of the signals are ensured; on the other hand, the structural strength of the outer protective shell 1 is improved, the outer protective shell is prevented from being deformed under the pressing force of a fastening piece in the specific installation process, and the connection reliability and the installation accuracy of the outer protective shell are ensured.
It is known that the sealing performance of the connection part between the Fakra connector and the fixed seat is important after the Fakra connector is connected with the fixed seat. When the processing is not good, the short circuit phenomenon of the lead can even be caused, so that the transmission of signals is influenced, and for this reason, a placing groove 11 is also formed on the bottom wall of the outer protective shell 1 around the central axis of the outer protective shell for sinking the sealing ring 5 (as shown in fig. 4 and 5) so as to ensure the tightness of the connection of the Fakra connector and the fixed seat. It should be noted that, as proved by specific experiments, the depth of the groove for placing the groove 11 should be smaller than the diameter of the sealing ring 5 by 0.1-0.2 mm, so that the sealing reliability of the Fakra connector and the fixing seat can be improved by the elastic deformation of the sealing ring 5 itself in the following process.
The ptfe composite seal ring itself is known to have the advantages of high corrosion resistance, stable physical properties, high and low temperature resistance, and low creep property, and therefore, the seal ring 5 is preferably a ptfe composite seal ring.
In the practical application process, the Fakra connector needs to be matched with a Fakra plate end connector for use. As shown in fig. 8, the Fakra board end connector is inserted, nested directly below the Fakra connector. The specific combination form of Fakra board end connector and Fakra connector is especially important to the normal transmission process of signal, and in view of this, fig. 6 shows the utility model discloses the solid-state diagram of interior shield shell in the Fakra connector can clearly be seen from, has seted up bar open slot 21 on the lateral wall of above-mentioned interior shield shell 2. The bar-shaped opening grooves 21 are formed by upward extending the bottom wall of the inner shielding shell 2, and the number of the bar-shaped opening grooves is set to be a plurality of, and the bar-shaped opening grooves are circumferentially and uniformly distributed around the central axis of the inner shielding shell 2. Therefore, on one hand, the requirement on the alignment precision of the Fakra plate end connector is effectively reduced, and the convenience of assembly is further improved; on the other hand, the Fakra plate end connector has certain floatability relative to the Fakra connector, and the phenomenon that the Fakra connector is damaged due to the fact that the Fakra plate end connector is under the action of lateral tension is avoided.
The metal terminal 4 and the plastic ferrule 3 are preferably integrally formed, that is, in the stage of forming the plastic ferrule 3, the metal terminal 4 is pre-placed in a cavity (not shown in the figure) of an injection mold thereof, so that the bonding strength between the metal terminal 4 and the plastic ferrule 3 is effectively improved, and the phenomenon that the normal transmission of signals is affected due to play in the actual application process is prevented.
In addition, generally speaking, in order to take into account the insertion difficulty and the combination stability, the assembly gap between the plastic ferrule 3 and the inner shielding shell 2 needs to be strictly controlled, so as to inevitably increase the molding and assembly difficulties of the two, therefore, a preferable scheme is provided, namely, after the plastic ferrule 3 is inserted into position relative to the inner shielding shell 2, a concave riveting protrusion 221 is formed on the side wall of the inner shielding shell 2 by applying force, and correspondingly, an annular groove 31 is formed on the outer side wall of the plastic ferrule 3 for avoiding the concave riveting protrusion 221 (as shown in fig. 4 and 7). Set up through above-mentioned technical scheme to relaxed the requirement to plastic lock pin 3 for interior shield shell 2 fit-up gap, and realized its reliable fixed with interior shield shell 2, prevented that plastic lock pin 3 from taking place "drunkenness" phenomenon in the practical application process.
In order to improve the position accuracy of the female riveting protrusion 221 and ensure that it is formed in the annular groove 31, an annular groove 22 may be formed on the outer side wall of the inner shield shell 2, in which the female riveting protrusion 221 is formed (as shown in fig. 4 and 6).
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
