Description

Connector with a plurality of connectors Technical Field The present application relates generally to the field of electrical devices, and more particularly to a connector, particularly for a vehicle, such as a FAKRA connector, mini-FAKRA connector, HFM connector, or the like. Background In existing connectors (e.g., radio frequency connectors), the first housing (e.g., a metal housing) and the outer conductor are typically secured to the second housing (e.g., a plastic housing) by staking, which results in a complex structure, cumbersome assembly process, and high manufacturing costs. In addition, in general, the boss buckle of the first shell is riveted with the second shell rib, which can lead to insufficient retention force and easy falling after high-temperature aging. Disclosure of utility model In order to overcome the above-described drawbacks of the prior art, the present application provides a connector comprising a first housing and a second housing fittable to each other, the first housing including a first housing main body and a columnar outer conductor protruding from a front flat surface of the first housing main body, the second housing including a second housing main body including a through hole provided on a rear flat surface of the second housing main body, the columnar outer conductor extending through the through hole to an inside of the second housing main body in a state where the first housing and the second housing are fitted together, the first housing further including at least one recess concavely formed on an outer peripheral surface of the columnar outer conductor, and the second housing further including at least one elastic snap formed at a periphery of the through hole, the elastic snap extending obliquely radially inward inside the second housing main body, the elastic snap being in contact with the corresponding recess in a state where the first housing and the second housing are fitted together, and the front flat surfaces of the first housing and the second housing contact each other. Accordingly, the holding force between the first housing and the second housing can be improved and the first housing can be prevented from falling back after assembly. Further, the first housing includes a plurality of the concave portions, which are arranged at equal intervals in the circumferential direction on the outer peripheral surface of the columnar outer conductor. Accordingly, the second housing can be connected to the first housing at different rotation angles with respect to the first housing, thereby improving the adaptability. Further, the second housing includes a plurality of the elastic snaps, which are arranged at the periphery of the through hole at equal intervals in the circumferential direction, the number of the elastic snaps being equal to the number of the concave portions. Accordingly, the connection between the first housing and the second housing can be further improved. Further, the second housing further includes at least one protrusion formed at a periphery of the through hole, the protrusion abutting on an outer peripheral surface of the columnar outer conductor in a state where the first housing and the second housing are assembled together. Accordingly, it is possible to prevent the shaking between the second housing and the first housing during use. Further, the second housing further includes a plurality of projections formed at the periphery of the through hole, each of the projections being disposed between adjacent two of the elastic snaps in the circumferential direction, the projections abutting on the outer peripheral surface of the columnar outer conductor in a state where the first housing and the second housing are assembled together. Accordingly, the second shell and the first shell can be prevented from shaking all around in the using process. Further, the first housing further includes at least one stopper protruding from the front flat surface of the first housing main body in a direction parallel to the protruding direction of the columnar outer conductor, and the second housing further includes at least one groove concavely formed from the rear flat surface of the second housing main body, the number of the stoppers being equal to the number of the grooves, the stoppers being inserted into the respective grooves in a state where the first housing and the second housing are assembled together. Accordingly, the connection between the first housing and the second housing can be further improved. Further, the second housing includes a plurality of the grooves, which are arranged around the through hole at equal intervals in the circumferential direction. Accordingly, the holding force can be improved in a balanced manner. Further, in a state where the first housing and the second housing are assembled together, the stopper is interference-fit engaged in the corresponding groove. Accordingly, the positioning accuracy can be improved and the o
