Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a sealed connector with a wire harness. Background Technology

[0002] Connectors enable the transmission of electrical energy and signals between two or more different electrical components, and therefore, they are widely used in various fields.

[0003] Sealed connectors are an important type of connector. They have certain sealing properties such as waterproof, oil-proof, and dustproof. In harsh environments such as immersion in water, humidity, and dust, the use of sealed connectors can effectively prevent liquids and dust from entering the interior of the connector, thereby avoiding problems such as short circuits, open circuits, and loose connections.

[0004] In the prior art, in order to achieve the sealing of the connector, a "dispensing" process is usually performed on the connector. Specifically, after the connector is assembled, sealant is applied to the mating position between the connector shell and the terminal. After the sealant cures, the gap between the connector shell and the terminal is sealed, thereby achieving the sealing of the connector.

[0005] However, when the connector has a wire harness, the above-mentioned "dispensing" process fails to effectively seal the connection between the terminal and the wire harness, and the connector still has the risk of short circuit or open circuit, requiring additional sealing treatment at the connection between the terminal and the wire harness.

[0006] In conclusion, how to provide a stable and reliable sealing structure for connectors with wire harnesses has become an urgent problem to be solved. Utility Model Content

[0009] In the above technical solution, the other side of the connector housing component relative to the wire harness assembly side is configured as a plug-in side; the end of the terminal exposed on the plug-in side of the connector housing component is configured as a plug-in end.

[0010] In the above technical solution, the sealant layer also covers at least a portion of the outer sheath / sealing sleeve of the wire harness.

[0011] In the above technical solution, a dispensing groove is provided on the wire harness assembly side of the connector housing component; the adhesive material of the sealing adhesive layer is injected into the dispensing groove of the connector housing component.

[0012] In the above technical solution, the top of the sealant layer arches up from the dispensing groove of the connector housing component to form an arched layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The sealed connector with wire harness of this utility model has a sealing layer on the wire harness assembly side of the connector housing component.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This embodiment provides a sealed connector with a wire harness for transmitting electrical energy and signals between two or more different electrical components.

[0022] Please see Figures 1-5 The sealed connector with wire harness in this embodiment includes a connector housing component 10, a terminal 20, and a wire harness 30.

[0024] The terminal 20 is an integrally formed metal component with good electrical conductivity, such as copper.

[0025] The wiring harness 30 includes at least a number of cables, which can be power lines or signal lines. Each cable in the wiring harness 30 includes a metal core 302 and a rubber outer sheath 301. The outer sheath 301 is used for insulation and signal shielding. In this embodiment, the wiring harness 30 also includes a sealing sleeve 303 (specifically a heat shrink sleeve).

[0026] One side of the connector housing component 10 is configured with a wire harness assembly side 102.

[0027] At least a portion of the terminal 20 is embedded in the connector housing member 10, and the end of the terminal 20 exposed on the wire harness assembly side 102 of the connector housing member 10 is configured as the wire harness assembly end 202.

[0028] The wire core 302 of the wire harness 30 is connected to the wire harness assembly end 202 of the terminal 20. Specifically, the wire core 302 of the wire harness 30 and the wire harness assembly end 202 of the terminal 20 are mechanically and electrically connected by welding or crimping.

[0029] In order to seal the sealed connector with wire harness in this embodiment, a sealing layer 40 is provided at the wire harness assembly side 102 of the connector housing component 10. The sealing layer 40 covers the wire harness assembly end 202 of the terminal 20, and the sealing layer 40 also covers the wire core 302 of the wire harness 30.

[0030] Specifically, the other side of the connector housing component 10 relative to the wire harness assembly side 102 is configured as a mating side 101, and the end of the terminal 20 exposed on the mating side 101 of the connector housing component 10 is configured as a mating end 201.

[0031] Furthermore, in order to improve the sealing performance of the sealed connector with wire harness in this embodiment, the sealing adhesive layer 40 also covers at least a portion of the outer sheath 301 / sealing sleeve 303 of the wire harness 30.

[0032] Furthermore, a dispensing groove 102a is provided on the wire harness assembly side 102 of the connector housing component 10. In this embodiment, an annular rib is integrally formed on the wire harness assembly side 102 of the connector housing component 10, and the internal space of the annular rib is the dispensing groove 102a. The adhesive material of the sealing layer 40 is injected into the dispensing groove 102a of the connector housing component 10 to prevent the adhesive material of the sealing layer 40 from overflowing to other locations.

[0033] Furthermore, the top of the sealant layer 40 arches from the dispensing groove 102a of the connector housing component 10 to form an arched layer 401, so that the sealant layer 40 can cover at least a portion of the outer sheath 301 / sealing sleeve 303 of the wire harness 30.

[0034] In this embodiment, the sealed connector with wire harness is manufactured by prefabricating terminals 20 and wire harness 30. Terminal 20 is then placed into a molding die of the connector housing component 10. Plastic material is injected into the die, and after the plastic material cools and solidifies, it is demolded to obtain an assembly of the connector housing component 10 and terminals 20. Figure 3 and Figure 5 As shown, at this time, the middle part of terminal 20 is embedded in the connector housing component 10. The end of terminal 20 exposed on the wire harness assembly side 102 of the connector housing component 10 is the wire harness assembly end 202, and the end of terminal 20 exposed on the insertion side 101 of the connector housing component 10 is the insertion end 201. Subsequently, the wire core 302 of the wire harness 30 and the wire harness assembly end 202 of terminal 20 are mechanically and electrically connected by welding or crimping, and the sealing sleeve 303 is fitted into the designated position (in Figures 1-3 In the illustrated embodiment, the designated position is the mating position between the wire core 302 of the wire harness 30 and the wire harness assembly end 202 of the terminal 20. Figure 4 and Figure 5In the embodiment shown, the designated location is the middle of the wire harness 30; finally, the adhesive material of the sealant layer 40 is injected into the dispensing groove 102a of the connector housing component 10 until the dispensing groove 102a is filled, and the adhesive material of the sealant layer 40 arches under the action of surface tension, forming an arched layer 401. After the adhesive material of the sealant layer 40 has cured, the sealant layer 40 covers the wire harness assembly end 202 of the terminal 20 and the wire core 302 of the wire harness 30. Figures 1-3 In the illustrated embodiment, the sealant layer 40 also covers at least a portion of the outer sheath 301 and the sealing sleeve 303 of the wire harness 30. Figure 4 and Figure 5 In the embodiment shown, the sealant layer 40 also covers at least a portion of the outer sheath 301 of the wire harness 30, thereby providing good sealing performance at the mating position of the wire core 302 of the wire harness 30 and the wire harness assembly end 202 of the terminal 20.

[0035] Understandably, in Figures 1-3 In the illustrated embodiment, the sealed connector with wire harness is male, and both the mating side 101 of the connector housing member 10 and the mating end 201 of the terminal 20 are configured as male. Figure 4 and Figure 5 In the embodiment shown, the sealed connector with wire harness is a female end, and the insertion side 101 of the connector housing component 10 and the insertion end 201 of the terminal 20 are both configured as female ends.

[0036] In this embodiment, a sealed connector with a wire harness has a sealing layer 40 disposed on the wire harness assembly side 102 of the connector housing component 10. The sealing layer 40 covers the wire harness assembly end 202 of the terminal 20 and also covers the wire core 302 of the wire harness 30. This provides good sealing performance for the mating position between the wire core 302 of the wire harness 30 and the wire harness assembly end 202 of the terminal 20, thereby providing a stable and reliable sealing structure for the connector with a wire harness.
