Description

connector Technical Field

[0001] This application generally relates to the field of electrical equipment, and more specifically to a connector, particularly a connector for vehicles, such as a FAKRA connector, a Mini-FAKRA connector, an HFM connector, and so on. Background Technology

[0002] In existing connectors (e.g., RF connectors), the first housing (e.g., a metal housing) and the outer conductor are typically fixed to the second housing (e.g., a plastic housing) by riveting. This arrangement results in a complex structure, cumbersome assembly process, and high manufacturing costs. Furthermore, the first housing often employs a back cover-less design, leading to insufficient retention force on the L-shaped insulator and a tendency for it to detach. Additionally, the bosses and clips of the first housing are typically riveted to the ribs of the second housing, which can also lead to insufficient retention force and easy detachment after high-temperature aging. Summary of the Invention

[0003] To overcome the aforementioned deficiencies in the prior art, this application provides a connector comprising a first housing and a second housing that can be assembled together along a first assembly direction, and at least one L-shaped inner conductor and at least one L-shaped insulator mounted in the first housing. Each L-shaped insulator wraps around the exterior of a corresponding L-shaped inner conductor. The first housing includes a first housing body and at least one cylindrical outer conductor extending from the front portion of the first housing body in a direction parallel to the first assembly direction. The rear portion of the first housing body opposite to the front portion in the first assembly direction and the bottom portion of the first housing body are open. A first end of each L-shaped inner conductor and a first end of each L-shaped insulator are located within a corresponding cylindrical outer conductor. A second end of each L-shaped inner conductor extends beyond the bottom portion of the first housing body. The second housing includes a second housing body, which includes a rear... The first housing includes a through-hole on its surface. When the first and second housings are assembled together, the columnar outer conductor extends through the through-hole into the interior of the second housing body. The first housing also includes a cover that can be assembled onto the first housing body along a second assembly direction perpendicular to the first assembly direction. The cover includes a rear cover portion for covering the rear portion of the first housing body, and a bottom cover portion extending from the rear cover portion in a direction parallel to the first assembly direction to cover the bottom of the first housing body. The rear cover portion includes a recessed insertion groove formed from its surface facing the interior of the first housing body and extending in a direction parallel to the second assembly direction. The first housing body includes an insertion rib fixed within it and extending in a direction parallel to the second assembly direction. The insertion rib can be inserted into the insertion groove to secure the cover to the first housing body. Accordingly, the cooperation between the cover and the first housing body prevents the L-shaped insulator from retracting and provides a stable and reliable holding force.

[0004] Furthermore, the rear cover includes at least one snap-fit ​​extending from the top of the rear cover in a direction parallel to the second assembly direction, and the first housing body includes at least one through-hole extending through the top of the first housing body. When the first housing body and the cover are assembled together, the snap-fit ​​engages with the corresponding through-hole. This achieves a stable connection between the cover and the first housing body, thereby preventing the cover from detaching after assembly.

[0005] Furthermore, the rear cover includes a first fitting formed on its surface facing the interior of the first housing body, and the first housing body includes a first mating member formed on the surface of the insert rib facing the rear cover. When the first housing body and the cover are assembled together, the first fitting and the first mating member are connected to each other in a form-fitting manner. This improves the connection stability between the cover and the first housing body.

[0006] Furthermore, the first fitting is a protrusion formed from the surface of the rear cover facing the interior of the first housing body, and the first mating member is a recess formed from the surface of the insertion rib facing the rear cover; or the first fitting is a recess formed from the surface of the rear cover facing the interior of the first housing body, and the first mating member is a protrusion formed from the surface of the insertion rib facing the rear cover. Accordingly, connection stability can be improved in a simple manner, thereby reducing manufacturing costs.

[0007] Furthermore, the cover includes at least one second fitting formed on the outer surface of either of the two opposing sides of the bottom cover, and the first housing body includes at least one second mating member formed on the inner surface of either of its two opposing sides. When the first housing body and the cover are assembled together, the second fitting and the second mating member are connected to each other. This further improves the connection stability between the cover and the first housing body.

[0008] Furthermore, the second fitting is a rib that protrudes from the outer surface of either of the two opposing sides of the bottom cover and extends in a direction parallel to the second assembly direction, and the second mating member is a slot that is recessed on the inner surface of either of the two opposing sides of the first housing body and extends in a direction parallel to the second assembly direction; or the second fitting is a slot that is recessed on the outer surface of either of the two opposing sides of the bottom cover and extends in a direction parallel to the second assembly direction, and the second mating member is a rib that protrudes from the inner surface of either of the two opposing sides of the first housing body and extends in a direction parallel to the second assembly direction. Accordingly, connection stability can be improved in a simple manner, thereby reducing manufacturing costs.

[0009] Furthermore, the bottom cover includes at least one through hole extending through the bottom cover in a direction parallel to the second assembly direction. When the first housing body and the cover are assembled together, the second end of each L-shaped insulator is engaged within the corresponding through hole. This provides a strong holding force for the L-shaped insulator and limits its movement, preventing it from retracting or falling off during insertion.

[0010] Furthermore, the first housing also includes a connecting portion fixed between the front portion of the first housing body and the at least one columnar outer conductor. The connecting portion includes at least one third fitting formed on its outer peripheral surface, and the second housing includes at least one third mating member formed on its inner peripheral surface. When the first housing and the second housing are assembled together, each of the third fittings and the corresponding third mating member is connected to each other. Accordingly, a stable connection between the first housing and the second housing can be achieved, preventing the first housing and the second housing from detaching after assembly, and providing sufficient retaining force.

[0011] Furthermore, the third fitting is a groove formed recessed from the outer surface of the connecting portion, and the third mating member is a claw extending from the inner circumferential surface of the second housing body; or the third fitting is a claw extending from the outer surface of the connecting portion, and the third mating member is a groove formed recessed from the inner circumferential surface of the second housing body. Accordingly, connection stability can be improved in a simple manner, thereby reducing manufacturing costs.

[0012] Furthermore, relative to the central axis of the first housing, which is parallel to the first assembly direction, the radial dimension of the connecting portion is smaller than the radial dimension of the first housing body, such that an annular stepped surface is formed at the front of the first housing body, and when the first housing and the second housing are assembled together, the rear of the second housing body abuts against the annular stepped surface. This prevents wobbling between the second housing and the first housing during use.

[0013] Furthermore, the bottom cover includes at least one fourth fitting formed at its front, and the second housing includes a fourth mating member formed at the rear of the second housing body. When the first housing and the second housing are assembled together, each of the fourth fittings and the corresponding fourth mating member is connected to each other. Accordingly, the connection stability of the first and second housings can be improved, and in particular, the stable connection between the cover and the first housing body can be further maintained.

[0014] Furthermore, the fourth fitting is a recessed insertion hole formed from the front of the bottom cover in a direction parallel to the first assembly direction, and the fourth mating member is a pin extending from the rear of the second housing body in a direction parallel to the first assembly direction; or the fourth fitting is a pin extending from the front of the bottom cover in a direction parallel to the first assembly direction, and the fourth mating member is a recessed insertion hole formed from the rear of the second housing body in a direction parallel to the first assembly direction. Accordingly, connection stability can be improved in a simple manner, thereby reducing manufacturing costs. Attached Figure Description
