The FAKRA (Fachkreis Automobile) standard connector is a radio frequency signal connector for use in connection with a vehicle camera. As shown in fig. 1 and 2, the vehicle camera has a housing 800 and a circuit board 700, and the circuit board 700 is provided in the housing 800. Connector 900 has terminals 910 and latch 920. The terminal 910 passes through the housing 800 and is connected to the circuit board 700, and the latch 920 is soldered to the terminal 910. In this way, the terminal 910 may be inserted into an external connection slot, and transmit an electronic signal of the circuit board 700 to the external connection slot; in addition, the positions of the tenons 920 welded on the terminals 910 can achieve the effects of foolproof and distinguishing the purpose of connecting wires, which can avoid misplug.

However, when the connector 900 of the FAKRA specification of the existing car camera is used to replace a different latch 920, the original latch 920 needs to be detached from the housing 800 and welded to the terminal 910, so that the new latch can be replaced, but the welding is released with a very time-consuming and labor-consuming process. In addition, after installing a new latch and reinstalling the connector 900 back to the housing 800, the air tightness test of the vehicle camera needs to be retested, otherwise there is a concern that the housing 800 may be in water.

Therefore, it is desirable to provide a new FAKRA compliant connector that does not disassemble the entire product when replacing the latch, thereby avoiding the trouble of re-performing the air tightness test after disassembly and improving the assembly efficiency.

As shown in fig. 3, 4 and 6, in one embodiment of the present invention, connector 1 is a FAKRA (Fachkreis Automobile) standard connector for connecting to a socket (not shown) of a vehicle camera. The connector 1 includes a housing 100, a circuit board 200, a connection terminal 10, a terminal connector 20, four adhesives 40, and two screws 50.

In one embodiment of the present invention, the housing 100 includes a perforation 110, two first limiting plates 120, and four dispensing slots 130. The through hole 110 is used for the connection terminal 10 to pass through. The first limiting plates 120 are outwardly extending plates from the surface of the housing 100 and are provided with first buckling parts 1201, and the two first limiting plates 120 are respectively located at two opposite sides of the connector 1 for clamping the terminal connector 20. In this embodiment, the first fastening portion 1201 is a through hole penetrating the first limiting plate 120. The four dispensing slots 130 are located below the terminal connector 20, and the four dispensing slots 130 are used for bonding the terminal connector 20, however, the number of the dispensing slots 130 is not limited to four, and can be changed to more than one according to design requirements. The circuit board 200 is used for controlling the electronic signal operation of the connector 1, the circuit board 200 is located inside the housing 100, and the housing 100 can protect the circuit board 200 from being damaged by external force.

In one embodiment of the present invention, the connection terminal 10 is a cylindrical circuit connection terminal. One end of the connection terminal 10 is exposed out of the housing 100 from the inside of the housing 100 through the through hole 110 to be inserted into an external slot of the vehicle camera; the other end of the connection terminal 10 is connected to the circuit board 200.

In one embodiment of the present invention, the terminal connector 20 is detachably connected to the housing 100 and includes a ring-shaped housing 21, a latch 22, two second limiting plates 23, and a housing bottom 24. As shown in fig. 3, 5 and 6, in one embodiment of the present invention, the housing bottom 24 is connected to the housing 100 by two screws 50. Two screws 50 are used to fix the terminal connector 20 to a specific position on the housing 100. However, the number of the screws 50 is not limited to two, and may be changed to any number of two or more according to design requirements.

The annular housing 21 is connected to the housing bottom 24 and surrounds the end of the connection terminal 10 exposed to the housing 100 such that the end of the connection terminal 10 of the housing 100 is located within the annular housing 21. The latch 22 is a latch structure conforming to FAKRA specifications and is provided on the outer side of the annular housing 21. When the connection terminal 10 is inserted into the slot of the external car camera, the locking tongue 22 is engaged with the locking groove at the corresponding position in the slot of the external car camera. If the assembler inserts the connection terminal 10 into the slot of the unmatched car camera, the locking tongue 22 will be locked with the unmatched locking groove to achieve the fool-proof effect. However, the number of the locking tenons is not limited to one, and as shown in the connector 1a of fig. 7, the terminal connector 20a includes an annular housing 21 and three locking tenons 22, 22a, 22b, and the three locking tenons 22, 22a, 22b are combined with three locking grooves at corresponding positions in a slot of another external vehicle camera. It should be noted that, in the fastening structure of the FAKRA specification, the positions and the number of the tenons have fixed specifications, so the number and the positions of the tenons according to the invention can be arbitrarily changed to the number and the positions according to the FAKRA specification.

As shown in fig. 5 and fig. 6, in an embodiment of the present invention, two second limiting plates 23 are connected to opposite sides of the bottom 24 for respectively clamping two first limiting plates 120, in this embodiment, the second limiting plates 23 are plate bodies extending outwards from the bottom 24, the second limiting plates 23 are provided with second fastening portions 231 opposite to the first fastening portions 1201, and the first fastening portions 1201 and the second fastening portions 231 may be fastened and fixed with each other, in this embodiment, the first fastening portions 1201 and the second fastening portions 231 may be through holes and buckles, respectively, and may be configured reversely in practical application. The bottom 24 is used for connecting with one side of the annular housing 21 near the housing 100, the bottom 24 is located above the through hole 110 and the dispensing slot 130, and four adhesives 40 can be respectively coated in the dispensing slot 130 to connect the housing 100 with the bottom 24, so that the position of the terminal connector 20 is kept stable.

When an assembler is to assemble the connector 1, first, as shown in fig. 3 and 4, the assembler should solder the connection terminal 10 to the circuit board 200 and pass the end of the connection terminal 10 inserted into the external slot outward through the through hole 110. The assembler can then fill each glue slot 130 with glue 40. Then, the assembling personnel can put the annular housing 21 into the connecting terminal 10, so that the housing bottom 24 covers each dispensing slot 130 and the through hole 110, and the adhesive 40 in the dispensing slot 130 adheres to the housing bottom 24, so that the terminal connecting piece 20 and the housing 100 can be combined in a stable position. In this way, the connector 1 is assembled, and the latch 22 is positioned to plug into the slot of the external car camera.

However, the manner of combining the terminal connector 20 and the housing 100 in the stable position is not limited to the above, and the assembler may clamp and fix each second limiting plate 23 to the corresponding first limiting plate 120, that is, combine the terminal connector 20 and the housing 100 in the stable position; or the screw 50 is passed through the bottom 24 of the housing and connected to the housing 100, so that the terminal connector 20 and the housing 100 are combined in a stable position; or the above three fixing methods are simultaneously performed so that the combination of the terminal connector 20 and the housing 100 may be more stable. It should be noted that the fixing manner using the second limiting plate 23 has the advantage of convenient and quick detachment, and the fixing manner using the adhesive 40 and the screw 50 has the advantage of better fixing effect, so that an assembler can choose a proper fixing manner arbitrarily in consideration of the use requirement.

If an assembler needs to remove the latch 22 of fig. 3 and install another latch conforming to FAKRA specifications, as shown in fig. 3, 4 and 6, the assembler can remove the screws 50 from the housing 100, remove the second limiting plates 23 from the corresponding first limiting plates 120, and slightly apply force to separate the bottom 24 and the adhesive 40, so that the terminal connector 20 can be removed from the connecting terminal 10 by hand. Next, as shown in fig. 7, the assembler can insert the annular housing 21 of the other terminal connector 20a into the connecting terminal 10, so that the bottom 24 covers each dispensing slot 130 and the through hole, and the second limiting plates 23 are fastened to the corresponding first limiting plates 120, and thus the terminal connector 20a and the housing 100 are combined in a stable position. Next, the assembler can insert the screw 50 through the bottom 24 and attach the housing 100, so that the combination of the fastener 30 and the housing 100 is more stable. In this way, the connector 1a of another type is assembled, and the tenons 22, 22a, 22b are positioned to be inserted into the slots of the external car camera.

By means of the design of the camera circuit structure and the connector, when the clamping tenons of different types conforming to the FAKRA standard are replaced, the whole product is not required to be disassembled, and when the shell is kept closed, only the terminal connecting piece and the clamping piece which are positioned outside the shell are disassembled, so that the clamping tenons can be easily replaced; therefore, the trouble that the airtight test is required to be carried out again after the disassembly can be avoided, and the assembly efficiency is improved.

It should be noted that the above is only an example and is not limited to the example. Such as those that do not depart from the basic structure of the invention, they should be construed as being limited to the scope of the invention as set forth in the appended claims.
