Technical Field

The utility model relates to the technical field of connectors, in particular to a novel connector mud and sand prevention sheath.

Background

In recent years, with the maturity of technology and the abundance of products, new energy automobiles gradually enter thousands of households. This is accompanied by the increasingly complex use environment of new energy vehicles, which is a great challenge for connectors on vehicles. At present, a host factory is convenient to assemble, the assembly efficiency is improved, and a direct push-pull type connector is mostly used on a vehicle. In such a connector, there is generally a movable part corresponding to the connector housing to achieve the locking function after the plug and the socket are inserted. If improper protection to the key position connector when arranging, receive silt, muddy water when the vehicle goes and splash etc. probably can lead to connector movable part to block, cause and can't pull out, cause the difficulty to follow-up maintenance, increase maintenance or maintenance cost.

If the connector cannot be pulled out normally, the subsequent product is difficult to overhaul, and the overhaul or maintenance cost is increased. If the movable part of the connector and even the whole connector can be protected, silt can be avoided from entering, and the fault that the connector is difficult to pull out is prevented or reduced. However, the existing technical solutions are all that the equipment end is directly connected with the protective sleeve (bolt connection, bayonet connection, etc.), which not only is inconvenient to assemble, but also introduces the possibility that the connected part may fail.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical problems that the protective sleeve is inconvenient to assemble and easy to break down, the utility model provides a novel connector mud and sand prevention protective sleeve.

The purpose of the utility model is realized by adopting the following technical scheme. According to the novel connector anti-sand sheath provided by the utility model, the sheath is divided into a plurality of parts along the insertion direction of the connector, the plurality of parts of the sheath are spliced and sleeved on the connector, meanwhile, the matching structure on the inner wall of the sheath is matched with the structure on the outer wall of the connector, so that the sheath is limited on the connector, and after the sheath is fixed on the connector, one end face of the sheath is tightly attached to a device panel in which the connector is inserted.

Furthermore, the splicing surfaces of the parts of the sheath are fixed through buckles after being butted.

Furthermore, at least one pair of matched splicing surfaces of the multiple parts of the sheath are fixed by adopting a buckle, and the other matched splicing surfaces are hinged with each other.

Furthermore, after the plurality of parts of the sheath are spliced and sleeved on the connector, the sheath is fixed on the connector in a binding mode of a binding belt.

Furthermore, the size of the end part where the end face of the sheath in contact with the equipment panel is larger than the size of other parts of the sheath, so that the contact face of the end face of the sheath with the equipment panel is increased.

Furthermore, the matching parts of the sheath, the equipment panel and the connector are provided with soft plastic formed by injection molding.

Further, a part of the connector is sleeved in the sheath.

Further, the sheath is sleeved on the whole connector.

Furthermore, the matching structure of the inner wall of the sheath is a protrusion which is clamped on the push-pull structure of the connector, so that the protrusion is limited with the push-pull structure of the connector in the push-pull direction.

Compared with the prior art, the utility model discloses an useful part lies in: need not between this sheath and the equipment panel to fix through connecting device, only lean on the structure of sheath and the cooperation of connector can with the equipment panel cooperation, reach the effect of preventing the silt, if need strengthen the leakproofness after the sheath assembly, so at the sheath with equipment panel contact position and with connector cooperation fixed position adopt secondary plastic envelope can. The novel sheath has the characteristics of low cost, simple and quick assembly, convenient and reliable installation, wide application range and the like.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

One embodiment of a novel connector anti-sand sheath of the present invention is shown in fig. 1-3. After the connector 3 is inserted into the equipment panel 1, the sheath 2 is sleeved on the connector 3, and meanwhile, the end surface 201 of the sheath 2 close to one end of the equipment panel 1 is tightly attached to the equipment panel 1. The outer contour of the sheath 2 is the outer contour of a revolving body, the inner contour of the sheath 2 is matched with the outer contour of the connector 3, the inner wall of the sheath 2 is provided with a protrusion 204, the connector 3 is fixed on the equipment panel 1 through a push-pull structure in an inserting mode, the sheath 2 is sleeved on the connector 3, and meanwhile the protrusion 204 is clamped on the push-pull structure, so that the push-pull structure and the protrusion 204 are limited in the push-pull direction, and the sheath 2 is tightly matched with the connector 3 after being sleeved on the connector 3 and is fixed in the push-pull direction. In other embodiments, the protrusion 204 may be other mating structures that mate with structures on the connector to limit the displacement of the jacket 2 on the connector. The end of the sheath 2 where the end face 201 is located has a larger size, so that the area of a matching surface of the end face 201, which is attached to the equipment panel 1, is increased, a better sealing effect is achieved, and meanwhile, the end face 201 abuts against the equipment panel 1 due to the limit between the protrusion 204 and the push-pull structure of the connector 2. For the convenience of installing the sheath 2 after the connector 3 is plugged, the sheath 2 is divided into two symmetrical parts along the axial direction, the surfaces of the two parts of the sheath 2 which are in mutual contact are splicing surfaces 202, the sheath 2 at the corresponding position of the splicing surfaces 202 is provided with a buckle 203, in the embodiment, the sheath 2 at the corresponding position of each splicing surface 202 is provided with two buckles 203, the two parts of the sheath 2 are symmetrically sleeved on the outer contour of the connector 3, and the two matched buckling surfaces 202 are buckled and locked with the buckles 203, so that the sheath 3 is fixed on the connector 3. The matching structure of the inner wall of the sheath and the connector 2 and the end surface 201 tightly attached to the equipment panel 1 can also be encapsulated by adopting a secondary injection molding mode, so that the contact part of the sheath 2, the connector 3 and the equipment panel 1 forms soft plastic, and the sealing effect after the sheath 2 is fixed is enhanced.

In other embodiments, the outer contour of the sheath 2 can also be designed to be square or other shapes; the splicing surfaces 202 matched with each other on one side of the two parts of the sheath 2 can be connected in a hinged mode, and the other side of the two parts is fixedly connected in a buckling mode 203; the sheath 2 can also be axially divided into a plurality of parts, and then the plurality of parts of the sheath are spliced and locked and fixed on the connector 3; after a plurality of parts of the sheath are sleeved on the connector, the sheath can be fixed in a mode of bundling a binding belt on the outer contour of the sheath 2 besides the mode of adopting a buckle; the sheath may be used to enclose at least a portion of the connector 3 within the sheath 2, as desired, and in this embodiment, the sheath 2 may be used to enclose the push-pull locking structure of the connector 3, and the sheath 2 may also comprise the connector assembly.
