Description

Technical Field

[0001] This utility model relates to the field of point connector technology, specifically, to an integrated shielded through-hole connector. Background Technology

[0002] In the connector industry, through-hole connectors are widely used in cable entry ports of equipment such as electrical boxes and control cabinets. Existing through-hole connectors typically use a plastic cover to press the seal against the mounting housing, providing basic dust and water resistance. However, this conventional connector structure usually lacks shielding and grounding functionality. When users need to transmit sensitive signals and select shielded cables, additional grounding treatment of the cable shielding layer is necessary.

[0003] The common practice is to extend the shielding layer outside the seal and connect a lead wire, crimp a grounding terminal at the joint of the lead wire, and finally tighten the terminal to the enclosure with screws to achieve grounding. This external grounding design has significant drawbacks: First, the cable shielding layer itself needs to be sealed to prevent media from entering the enclosure. Furthermore, after the shielding layer is extended, an irregular "Y"-shaped fork structure is formed between the cable body and the grounding lead wire. This structure disrupts the regular geometry of the connector mounting area, making it impossible to use standard, regularly shaped seals for effective sealing; typically, potting is used. This sealing method requires a curing time for the potting material, significantly extending the product processing cycle and affecting production efficiency. Moreover, the potting quality is highly dependent on the operator's skill level and environmental conditions, easily leading to problems such as air bubbles, uneven filling, or poor adhesion, resulting in poor seal consistency and unreliable reliability. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to provide an integrated shielded through-hole connector that integrates an efficient and reliable shielded cable grounding function without compromising the standard sealing structure of the through-hole connector, thereby eliminating the need for cumbersome and low-quality external lead grounding and potting sealing methods.

[0005] The present invention solves the above problems through the following technical solution:

[0006] An integrated shielded through-hole connector includes: a housing, a sealing ring, an outer shielding ring, an inner shielding ring, a cable assembly, and a sealing body; the housing has a plurality of cable through holes axially formed for mounting the cable assembly; the end face of the housing near the enclosure has a groove surrounding all the cable through holes, and the sealing ring is disposed in the groove to seal the enclosure and the housing, enclosing the cable assembly within the sealed area; the cable assembly includes a first cable, which passes through the cable through holes and the sealing body, and the sealing body achieves a seal between the tail end of the housing and the first cable; the portion of the first cable extending out of the front end of the housing peels off the outer rubber of the shielding layer to place the inner shielding ring between the inner rubber of the battery core and the shielding layer, and the outer shielding ring is placed over the shielding layer, so that the shielding layer is located between the inner shielding ring and the outer shielding ring; the outer shielding ring includes a crimping area and a contact area, the crimping area is crimped and fixed to the inner shielding ring, and the contact area has a plurality of elastic contact points on the front end face of the housing for conducting electricity to the enclosure when the housing is installed with the enclosure.

[0007] As a further improvement, the rear end of the housing is covered with a tail cap to limit the sealing body.

[0008] As a further improvement, the tail cap is fixed by a hook and a mounting bracket on the housing.

[0009] As a further improvement, the cable assembly also includes a second cable, which, along with the first cable, extends through the tail cap.

[0010] As a further improvement, the sealing body is provided with a first sealing hole and a second sealing hole. The first sealing hole is used to accommodate the first cable, and the second sealing hole is used to accommodate the second cable. The inner circumferential surfaces of the first sealing hole and the second sealing hole, as well as the outer ring of the sealing body, are provided with raised ribs.

[0011] As a further improvement, the plurality of elastic contact points are evenly distributed along the circumference and are in the shape of petals.

[0012] As a further improvement, the front end of the housing is provided with a contact point receiving groove to accommodate the plurality of elastic contact points.

[0013] As a further improvement, the housing has a flat flange and a hollow cylindrical part. The flat flange has at least two housing mounting holes and at least one cable through hole. The housing mounting holes are arranged through the flat flange, and a threaded sleeve is provided in the housing mounting hole for one end of a screw to pass through the threaded sleeve and connect to the housing. The cable through hole is arranged through the flat flange and the cylindrical part so as to install cable assemblies through the cable through hole.

[0014] As a further improvement, the cable vias are configured to be four.

[0015] As a further improvement, the housing is made of plastic material.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] (1) In this utility model, a grounding path consisting of an inner shielding ring and an outer shielding ring is directly set on the shielding layer of the first cable inside the housing of the perforated connector to form an integrated shielding grounding structure; so that the connection between the shielding layer and the grounding structure is completed during the assembly of the perforated connector, and no external lead wire operation is required after installation.

[0018] (2) Since the shielding and grounding of this utility model is completed inside the housing of the through connector, there are no additional leads outside, and the sealing problem is solved by the sealing element with a regular shape. Therefore, there is no need to carry out potting operation, which shortens the production cycle and improves the consistency and reliability of product quality.

[0019] (3) The contact area of ​​the outer shielding ring of this utility model is designed with multiple elastic contact points in the shape of petals. When the connector is inserted into the mounting hole of the housing, these elastic contact points are compressed between the contact point receiving groove of the housing and the housing, forming a large-area, low-resistance reliable electrical connection. The shielding grounding is automatically completed at the same time as the through-hole connector is installed. The operation is simple, the contact is reliable, and the additional grounding wire installation steps are eliminated. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Example:

[0029] See attached document Figure 1-5 An integrated shielded through-hole connector, the through-hole connector mainly includes: a housing 1, a tail cap 2, a screw sleeve 3, a sealing ring 4, a shielding outer ring 5, a shielding inner ring 6, and a sealing body 9;

[0030] The housing 1 is made of plastic and has a flat flange 101 and a hollow cylindrical part 102. The housing 1 has two housing mounting holes 104 and four cable through holes. The housing mounting holes are located at two opposite corners of the flat flange 101. The housing mounting holes are provided with threaded sleeves 3, which can withstand the torque generated by the screws when the housing 1 is installed, so that one end of the screw passes through the threaded sleeves 3 to install the through connector onto the housing 10. The cable through holes are provided through the flat flange 101 and the cylindrical part 102. Both ends of the cable assembly are provided through the cable through holes so that the cable assembly can be installed through the cable through holes.

[0031] The front end of the flat flange 101 of the housing 1, that is, the end face near the box 10, has a groove 105 around all the cable through holes for placing the sealing ring 4. When the through connector is installed into the box 10, the sealing ring 4 can wrap the cable assembly in the sealing area, and at this time the cable shielding layer does not need to be sealed with glue.

[0032] The cable assembly includes at least a first cable 7 and a second cable 8. A sealing body 9 is disposed inside the cylindrical portion 102 of the housing 1. The first cable 7 passes through the sealing body 9 to compress the sealing body 9 through the cylindrical portion 102 of the housing 1 and the first cable 7, thereby sealing the space between the cylindrical portion 102 and the first cable 7. The tail cap 2 is fitted onto the cylindrical portion 102 of the housing 1, i.e., the tail, to limit the sealing body 9. The second cable 8 also passes through the tail cap 2. Preferably, the hook of the tail cap 2 cooperates with the mounting platform 103 of the cylindrical portion 102 of the housing 1 to fix the sealing body 9 in the cylindrical portion 102.

[0033] Specifically, the sealing body 9 is designed with a first sealing hole 901 located on the left and right sides of the sealing body and a second sealing hole 902 located in the middle of the front and rear of the sealing body. The first sealing hole 901 is used to accommodate the first cable 7, and the second sealing hole 902 is used to accommodate the second cable 8. The inner circumferential surfaces of the first sealing hole 901 and the second sealing hole 902 are designed with raised ribs 903 for forming a seal with the first cable 7 and the second cable 8. The outer ring of the sealing body 9 is also designed with raised ribs 903 for sealing between the sealing body 9 and the housing 1.

[0034] The outer rubber of the shielding layer is peeled off from the front end of the first cable 7 extending out of the housing 1 so that the inner shielding ring 6 is placed between the inner rubber of the battery core and the shielding layer. The outer shielding ring 5 is then placed on the outer shielding layer so that the shielding layer is located between the inner shielding ring 6 and the outer shielding ring 5. The outer shielding ring 5 is composed of a crimping area 501 and a contact area 502. The inside of the crimping area 501 is in contact with the inner shielding ring 6 and is fixed to the first cable 7 after crimping. The contact area 502 is connected to the tail of the crimping area 501. The contact area 502 has multiple elastic contact points 503 evenly distributed along the circumference on a plane perpendicular to the circular crimping area. The multiple elastic contact points 503 are petal-shaped, and the front end of the housing does not have a contact point receiving groove to accommodate the multiple elastic contact points 503. When the through connector is installed in the housing 10, the contact points 503 are connected to the housing to complete the grounding of the shield.

[0035] The perforated connector of this invention can ground the cable shielding layer inside the housing. After installation in the enclosure, the shielding conduction position is located in the sealed area, eliminating the need for lead wires and potting sealant on the shielding layer. This optimizes the wire harness processing technology and improves the shielding transition quality. At the same time, there are multiple sealing holes on the tail cap and the sealing body, which can seal multiple cables of different specifications at the same time. The perforated connector is compact, occupies little space, and has wider adaptability.

[0036] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
