Description

Floating connector assembly

Technical Field

The utility model belongs to the technical field of the connector, concretely relates to floating connector assembly.

Background

Under the circumstances that problems such as energy crisis, environmental pollution and the like are troubled, safety, environmental protection and energy conservation become the subjects of current automobile development, and hydrogen fuel cell automobiles are highly valued and strongly supported by the national government due to the advantages of high efficiency, cleanness and the like. The fuel cell DC-DC converter plays a very important role as a key component of a hydrogen fuel cell automobile. With the popularization of hydrogen fuel cell vehicles and the technological innovation in the future, the DC-DC converter as a key component tends to be more and more developed in the direction of miniaturization, light weight and high power density, and the problems of electrical connection, structural layout and the like of internal power devices are particularly prominent. The existing connection mode of the cable and the circuit board has the following problems: (1) the traditional soldering mode needs manual operation, so that the efficiency is low and the reliability is not high; (2) the common screw locking terminal occupies a large space on the surface of a printed circuit board in connection, and a wire harness is possibly interfered with a device and is not suitable for automatic assembly; (3) ordinary wire to board connector current-carrying capacity on the market is not enough to and the volume is great, and all is that the reed structure involves a plug dynamics problem, makes the circuit board produce deformation, stress scheduling problem among the assembly and disassembly process, is unfavorable for the dismouting maintenance convenience that multi-point position connects on the printed wiring board, and the connector of heavy current is expensive in addition.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of prior art and providing a floating connector assembly, the utility model discloses realize convenient and reliable being connected between printed wiring board and the cable.

The technical scheme of the utility model as follows: the utility model provides a floating connector assembly, includes connector housing and terminal, connector housing includes a plurality of independent cavitys, each the inside card that stops that is provided with of cavity, the terminal includes locking portion and wire fixed part, be provided with the screw hole on the locking portion.

Preferably, the side surface of the connector housing is provided with a buckle corresponding to each cavity position.

Preferably, the top of the connector housing is provided with a limiting protrusion.

The utility model has the advantages that:

(1) the terminals and the connector shell are installed in a matched mode through the clamping parts and the anti-return clips, so that convenience is provided for assembling of the connector assembly, and the allowance in perpendicularity and position degree is provided for installation of the terminals and the circuit board;

(2) the connector shell and the shell are fixed in a buckling mode, so that the primary positioning, the verticality and the position tolerance are provided for the installation of the connector assembly and the circuit board;

(3) the floating design enables each terminal to independently float in the axial direction, provides the tolerance on the flatness for the whole circuit board mounting plane, and simultaneously eliminates the stress problem caused by the uneven contact surface.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, a floating connector assembly comprises a connector housing 1 and terminals 2, wherein the connector housing 1 includes a plurality of independent cavities, each cavity accommodates one terminal 2, and any number of cavities can be set according to requirements, the number of the cavities in this embodiment is 4, that is, the connector assembly can fix 4 cables at a time, a retaining clip 3 is disposed inside each cavity, the terminals 2 include a clamping portion 4 and a wire fixing portion 5, the clamping portion 4 deforms and fixes the retaining clip 3 to a space above the retaining clip 3 by an external force, and a gap exists between the clamping portion 4 and the retaining clip 3, so as to ensure that the terminals 2 can move axially in a limited space, provide convenience for assembling the connector assembly, provide perpendicularity and position tolerance for installing the terminals 2 and a circuit board 9, and simultaneously, each terminal 2 is designed to float independently in the axial direction, the tolerance on the flatness is provided for the whole circuit board 9 mounting plane, the stress problem caused by uneven contact surface is eliminated, the wire fixing part 5 is used for fixing a cable, and the clamping part 4 is provided with a threaded hole.

In this embodiment, the side of the connector housing 1 is provided with a buckle 6 corresponding to each cavity, and the buckle 6 is used for fixing the connector assembly to the housing 8 by abutting against the housing 8, so as to provide the tolerance on the primary positioning, the verticality and the position degree for the installation of the connector assembly and the circuit board 9.

The top of the connector shell 1 is provided with a limiting bulge 7, the limiting bulge 7 can be designed into a shape like a Chinese character 'yi', a 'ten' or a 'T', and the limiting bulge 7 is matched with a hole reserved on the circuit board 9, so that the position of the connector assembly can be limited after the connector assembly is plugged.

The utility model discloses fixed process:

terminal 2 that will fix the cable corresponds in inserting the cavity of connector housing 1, through the deformation of stopping card 3 and resume deformation with terminal 2 fixed to the cavity of connector housing 1, the connector assembly that will assemble passes casing 8 and butt circuit board 9, thereby can accomplish the preliminary fixed of connector assembly through the deformation of buckle 6, thereby accomplish being connected of cable and circuit board 9 with terminal 2 fixed to circuit board 9 through the screw.
