Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings only 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 order to facilitate the technical solution disclosed by the present invention to be fully understood by those skilled in the art, the following detailed description is made in conjunction with the specific embodiments, and fig. 1 shows a schematic three-dimensional assembly diagram of the Fakra90 ° elbow connector assembly structure with good sealing performance in the present invention, and it can be seen that the assembly structure mainly comprises the Fakra90 ° elbow connector 1 and the coaxial cable 2 which are mutually inserted and matched. The Fakra90 ° elbow connector 1 includes a metal conductor housing 11, a plastic insulator 12, and a conductive terminal 13. The metal conductor housing 11 is formed by connecting a main body section 111 and a cable inserting section 112 at an angle of 90 degrees. The conductive terminals 13 are inserted into the plastic insulator 12 and inserted into the body section 111 as a whole. The coaxial cable 2 is inserted into the cable insertion section 112, connected to the conductive terminal 13, and electrically connected thereto. By adopting the 90-degree bending design for the metal conductor shell 11, the requirement on the installation space is effectively reduced, and the Fakra 90-degree bending connector 1 is convenient to carry out installation operation (shown in figures 2-5).

As shown in fig. 2-7 and 10-12, the Fakra90 ° elbow connector 1 includes a metal conductor housing 11, a plastic insulator 12, conductive terminals 13, a sealant 14, and a sealing plate 15. The metal conductor housing 11 includes a main body section 111 and a cable insertion section 112 that make a90 ° angle joint. A partition 1111 is disposed in the main body section 111 to divide the inner cavity thereof into an upper accommodating cavity 1112 and a lower accommodating cavity 1113. The plastic insulator 12 is formed by connecting a limiting seat 121 and an inserting column 122. The limiting seat 121 is arranged in the lower accommodating cavity 1113 and is limited by the partition 1111 in axial displacement. The insertion column 122 is formed by extending the top wall of the stopper seat 121 upwards and passes through the partition 1111. The insertion hole 1221 is disposed in the insertion column 122 for the conductive terminal 13 to be inserted therein and simultaneously penetrating through the position-limiting seat 121. A transverse accommodating cavity 1121 is formed in the cable insertion section 112 and communicates with the lower accommodating cavity 1113. The coaxial cable 2 passes through the transverse receiving cavity 1121 and is connected to the conductive terminal 13 for electrical conduction. The sealant 14 is formed in the lower accommodating chamber 1113, and correspondingly, a glue injection port 1114 for communicating with the lower accommodating chamber 1113 is formed on the main body section 111. The sealant 14 fills the gaps between the stopper 121 and the lower accommodating cavity 1113 and between the coaxial cable 2 and the transverse accommodating cavity 1121. The glue injection port 1114 is formed on the bottom wall of the main body section 111. The sealing plate 15 is fixed on the main body section 111 and seals the glue injection port 1114. By adopting the technical scheme, the existence of the sealing colloid 14 not only increases the connection firmness between the coaxial cable 2 and the conductive terminal 13 to a certain extent, but also avoids the phenomenon that the conductive terminal 13 and the plastic insulator 12 axially float along the axial direction under the action of the exciting force. More importantly, the existence of the sealing colloid 14 also effectively prevents external water or water vapor from entering the interior of the Fakra90 DEG elbow connector 1 through the coaxial cable 2, thereby ensuring the transmission stability and reliability of signals and current.

As shown in fig. 2, 3 and 4, the coaxial cable 2 is preferably formed by sequentially sheathing a center conductor 21, an inner insulating layer 22, a shielding mesh layer 23 and an outer sheath layer 24 from inside to outside. The central conductor 21 and the inner insulating layer 22 are simultaneously inserted into the transverse housing cavity 1121, and the central conductor 21 is directly electrically conducted to the conductive terminal 13. The sealant 14 directly fills the gap between the inner insulating layer 22 and the transverse receiving cavity 1121.

In order to further improve the sealing and water-resistant performance, as shown in fig. 1, 2, 3 and 4, the Fakra90 ° corner connector assembly structure can be additionally provided with a heat-shrinkable sleeve 3 according to different practical application occasions. After the coaxial cable 2 is inserted into the transverse accommodating cavity 1121, the heat shrinkable sleeve 3 is sleeved on the outer sheath layer 24 and the cable insertion section 112. In the actual assembly process, firstly, shrink sleeve 3 is sleeved on coaxial cable 2, then coaxial cable 2 is inserted and assembled on Fakra90 ° elbow connector 1, thermal shrink sleeve 3 is axially dragged until a preset position is reached, and finally, thermal shrink sleeve 3 is subjected to heating treatment, so that the shrink deformation is generated to realize the tight wrapping of outer sheath layer 24 and cable insertion and assembly section 112.

As shown in fig. 1 to 7, a coming-off prevention portion is provided on the cable insertion section 112. The anti-dropping portion is formed by a plurality of annular convex strips which are continuously extended outwards from the outer side wall of the cable inserting section 112 and are arranged in parallel. Through adopting above-mentioned technical scheme to set up to improved the stability of thermal shrinkable sleeve 3 relative fixed position effectively and not warp, avoided it to carry out the emergence of axial float phenomenon because of receiving the exogenic action.

As a further optimization of the assembly structure of the Fakra90 ° elbow connector with good sealing performance, as shown in fig. 6, 7, 8 and 9, a stopper 1115 may be added to the main body section 111. The limiting part 1115 is formed by extending at least one limiting groove 11151 which is formed by extending the inner side wall of the lower accommodating cavity 1113 and is circumferentially and uniformly distributed around the central axis of the lower accommodating cavity 1113. After the molding of the sealant 14 in the lower accommodating cavity 1113 is completed, a series of limiting protrusions (as shown in fig. 3 and 4) completely matching with the limiting grooves 11151 are formed on the outer sidewall of the sealing compound 14 under the action of the limiting grooves 11151, so that even if the Fakra90 ° corner connector assembly is subjected to an excitation force during the practical application, the sealing compound 14 does not circumferentially rotate in the lower accommodating cavity 1113, thereby ensuring good sealing of the gaps between the limiting seat 121 and the lower accommodating cavity 1113 and between the coaxial cable 2 and the transverse accommodating cavity 1121.

It is known that the Fakra90 ° corner connector assembly may take a variety of designs to achieve a secure attachment to the vehicle body, however, a simple design and easy to later maintain, rework embodiment is proposed herein, as follows: as shown in fig. 5, a flange mounting plate 113 may be added to the metal conductor housing 11 to detachably couple with the vehicle body by means of bolts. The flange mounting plate 113 is formed by extending the side wall of the main body section 111 outward in the circumferential direction. The flange mounting plate 113 is provided with a coupling through-hole 1131 adapted to the bolt.

Finally, it should be noted that the rubber seal ring 4 (shown in fig. 1-4) may also be lined between the Fakra90 ° elbow connector 1 and the vehicle body for the purpose of further enhancing the sealing performance of the Fakra90 ° elbow connector assembly. An annular receiving groove 1132 (shown in fig. 5) surrounding the main body section 111 and adapted to receive the rubber seal ring 4 is formed in the flange mounting plate 113. In this way, water or water vapor can be effectively prevented from entering the interior of the Fakra90 ° elbow connector 1 through the fitting gap between the connector and the vehicle body, and the transmission stability and reliability of signals and current are further ensured.
