Description

Connector {Connector}

The present invention relates to connectors.

A connector combines with a counterpart connector to make an electrical connection, and performs signal connections in various forms. This connector and its counterpart connector are the male connector and female connector, and the internal terminals are combined with each other to perform signal connection.

When performing an electrical connection between connectors, waterproofing is required, so a seal is installed between connectors that are joined together to prevent water intrusion. In this way, if the seal placed between two connectors is not in a straight line and one connector is tilted with respect to the other connector, parts where the seal is compressed and parts where it is not compressed will occur, preventing proper waterproofing. It won't happen. This tilting of one side of the connector with respect to the other side of the connector may occur when an external force is applied to the cable extending from the connector.

In this way, if the connector on one side and the connector on the other side are not coupled in a straight line, the coupling between the respective terminals is not properly achieved, and there is also a problem of severe vibration or noise generation.

In addition, there is a problem that the seal that acts as a waterproofing function between connectors is pushed during the joining process of the connectors, and the seal is not installed correctly between the connectors, resulting in loss of waterproofing function.

Therefore, it is necessary that the connectors that are coupled to each other to form electrical coupling between terminals are coupled so that they are exactly in a straight line in the connector coupling and disengagement directions, and that this coupling state is maintained.

Additionally, in describing the components of embodiments of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are only used to distinguish the component from other components, and the nature, sequence, or order of the component is not limited by the term. When a component is described as being "connected," "coupled," or "connected" to another component, that component may be directly connected or connected to that other component, but there is no need for another component between each component. It should be understood that may be “connected,” “combined,” or “connected.”

Hereinafter, the configuration of a connector according to an embodiment of the present invention and a connector assembly having the connector will be described with reference to the attached drawings.

In Figure 1, a first connector 10 is disclosed. The first housing 11 may form the exterior of the first connector 10. The terminal unit 20, which will be described below, can be coupled to the first housing 11 to form the first connector 10. Here, the first housing 11 can be replaced with one of various shapes in consideration of coupling with the second connector 60, which is a counterpart connector. Therefore, the terminal unit 20 can be used as is, and the first housing 11 can be replaced with one with a different configuration, such as a key code, in consideration of coupling with the counterpart connector.

The first housing 11 may be made of an insulating material. The first housing 11 may be made of an insulating synthetic resin material. The first housing 11 may be made by injection molding. There is a penetration space 12 penetrating the first housing 11 front and rear. Parts of the terminal unit 20 and the second connector 60 may be inserted and positioned in the through space 12. The penetration space 12 is formed to penetrate the first housing 11 in the front and rear direction, and the terminal unit 20 can be inserted into the penetration space 12 from the rear of the first housing 11. there is. As can be seen in FIG. 2, a locking protrusion 14 may be formed on the inner surface of the through space 12. The locking protrusion 14 may be formed in plural numbers surrounding the inner surface of the through space 12. The position of the hook 14 corresponds to the hook channel 26, which will be explained below.

There may be a fastening lever 16 on one side of the outer surface of the first housing 11. The fastening lever 16 is for fastening with the second connector 60. A fixture 18 is detachably installed on the other side of the outer surface of the first housing 11. The fixture 18 has a protrusion (not shown) protruding into the through space 12, and the protrusion plays the same role as the locking protrusion 14. The fixture 18 is partially positioned away from the first housing 11 before the terminal unit 20 is mounted in the through space 12, and then when the terminal unit 20 is in the through space 12. When mounted, the entire unit can be moved to come into close contact with the outer surface of the first housing 10. In this case, the protrusion protrudes into the through space 12 and can be seated and hung on the hanging channel 26 of the terminal unit 30.

The configuration of the terminal unit 20 will be described. The terminal unit 20 may be installed at the tip of the coaxial cable 22, for example. The terminal unit 20 is installed in the first housing 11 and can perform signal connection with the second connector 60. Additionally, the grounding function may be performed in cooperation with the grounding network (not shown) of the cable 22.

A shell housing 24 may form the exterior of the terminal unit 20. The shell housing 24 may be made of a conductive metal material. The shell housing 24 may also serve as a current conductor for grounding between the second connector 60 and the cable 22. The shell body 25 may form the skeleton of the shell housing 24. The shell body 25 may form the skeleton of the shell housing 24. The shell body 25 can be made by machining a metal material.

A hanging channel 26 may be formed on one outer surface of the shell body 25. The hook 14 of the first housing 11 or the protrusion of the fixture 18 may be hung on the hook channel 26. The hanging channel 26 may be formed in a circular shape. The hanging channel 26 may be formed on the outer surface of the connector 30, which will be described below.

The shell body 25 may have a cable penetration pipe 28 extending in one direction. The cable 22 may be positioned to pass through the inside of the cable penetration pipe 28 into the shell inner space 32, which will be described below.

As shown in Figure 3 or Figure 9, there may be a connector 30 on one side of the shell body 25. The connection pipe 30 may be located within the through space 12 of the first housing 11. The connection pipe 30 may be formed to extend in the direction in which the terminal unit 20 is mounted and separated from the first housing 11. The extension direction of the connection pipe 30 and the extension direction of the cable penetration pipe 28 may be perpendicular to each other.

A shell internal space 32 may be formed in the shell housing 24 to penetrate the connection pipe 30 and the shell body 25. An inner housing 46, which will be described below, may be installed in the shell inner space 32. The shell inner space 32 may be opened to the opposite side of the shell body 25 where the connection pipe 30 is located. The shell inner space 32 can be formed even through the cable penetration pipe 28. Accordingly, when viewed in side cross-section, a shell internal space 32 may be formed inside the shell body 25 in a 'T' shape or an almost 'L' shape. The shell internal space 32 has the following As will be described, the first ground contact 40, the inner housing 46, the first terminal 50, the terminal connector 58, the cable 22, etc. may be located.

A seal seating portion 34, an overlap portion 36, and the hanging channel 26 may be formed sequentially in the longitudinal direction of the connector 30 surrounding the outer surface of the connector 30 of the shell housing 24. . A seal 35 may be seated on the seal seating portion 34. The seal seating portion 34 is a ring-shaped space and can be divided from the surrounding area by steps 34' on both sides. One of the steps 34' may be formed around the tip of the connection pipe 30, and the other may be formed around the connection pipe 30 at the opposite end of the seal seating portion 34. The seal seating portion 34 is formed between the steps 34'. Among the steps 34', the upper surface of the step 34' on the overlap part 36 forms a continuous surface with the overlap part 36.

Among the steps 34', the one on the free end of the connector 30 has an overall predetermined outer diameter, and when combined with the second connector 60, the second internal space of the second connector 60 ( A predetermined gap may be formed between the inner surface of 63). That is, the outer diameter of the step 34' becomes relatively smaller than the inner diameter of the corresponding position of the second internal space 63. Here, the gap between the step 34' and the inner surface of the second internal space 63 is preferably 0.09 mm or less. If a gap exists in this way, the coupling force can be relatively reduced when the first connector 10 and the second connector 60 are coupled.

Among the steps 34', those on the free end side of the connector 30 are the front-to-back length of the second internal space 63 (coupling/separation direction between the first connector 10 and the second connector 60). It is better to be located further inside the midpoint (M) of the length. This means that the connection pipe 30 goes relatively deeper into the second internal space 63. In this way, it can be seen in FIG. 4 that the step 34' is located further inward than the midpoint M in the longitudinal direction of the second internal space 63.

The seal 35 mounted on the seal seating portion 34 may be made of an elastic material, such as rubber. The seal 35 has a cylindrical shape, and the inner diameter of the seal 35 may be slightly smaller than the outer diameter of the seal seating portion 34 of the connecting pipe 30. Accordingly, the inner surface of the seal 35 can be installed in close contact with the outer surface of the seal seating portion 34.

The overlap portion 36 is a portion that overlaps and comes into close contact with the inner surface of the second internal space 63 of the second connector 60. It is a part of the connection pipe 30 that is formed so that the outer diameter gradually increases. That is, the outer diameter of the overlap portion 36 may gradually increase from the tip of the connection pipe 30 toward the shell body 25. Accordingly, the overlap portion 36 may be inclined toward the shell body 25. The outer diameter at each position of the overlap part 36 has different values, and the outer diameter of some sections of the overlap part 36 is the second internal space 63 of the second connector 60, which will be explained below. It is smaller than the inner diameter of , and in the remaining sections, it is larger than the inner diameter of the second internal space 63. Accordingly, the section of the overlap portion 36 having an outer diameter larger than the inner diameter of the second inner space 63 may be press-fitted into the inner surface of the second inner space 63.

A partition 37 may be formed in a ring shape between the overlap portion 36 and the hanging channel 26. The locking protrusion 14 of the first housing 11 may be hung on the partition protrusion 37 . The locking protrusion 14 can be positioned within the hooking channel 26 and hung on the partition protrusion 37.

A cap 38 may be installed at the rear entrance of the shell inner space 32 formed in the shell body 25. The cap 38 may serve to shield the shell inner space 32 from the outside. The cap 38 may be made of metal material. The cap 38 may be disk-shaped. Of course, the shape of the cap 38 may be such that the shell inner space 32 is open to the rear of the shell body 25. The outer diameter of the cap 38 is slightly larger than the inner diameter of the shell inner space 32 at the corresponding location. Accordingly, the cap 38 can be press-fitted into the shell inner space 32.

A plurality of protrusions 38' surrounding the outer peripheral surface of the cap 38 are arranged at predetermined intervals. The plurality of protrusions 38' are arranged at regular intervals, so that gaps are formed between the protrusions 38'. In Figure 13, the protrusion 38' is clearly shown. The protrusion 38' may be slightly crushed when the cap 38 is pressed into the shell inner space 32.

A cap seal 39 may be installed between the cap 38 and the shell body 25. The capseal 39 may be made of an elastic material. The capseal 39 may be made of an insulating material. The capseal 39 serves as waterproofing and insulation. That is, the cap seal 39 can play the role of securing an insulating distance between the cap 38, which is made of a metal material, the first terminal 50, and the core wire 22' of the cable 22. The capseal 39 may also serve to block water from entering the shell inner space 32.

The specific configuration of the capseal 39 is shown in FIGS. 13 and 14. The capseal 39 may have an overall disk shape. The capseal body 39-1 may form the skeleton of the capseal 39. The capseal body 39-1 may have a disk shape. There may be a connecting neck (39-3) of relatively thin thickness surrounding the edge of the capseal body (39-1). The connecting neck (39-3) is a part that connects the capseal body (39-1) and the compression portion (39-5) to be described below. The connecting neck (39-3) is made to be relatively thinner than the capseal body (39-1) and the compressed portion (39-5). Accordingly, a concave channel 39-4 may be formed in a circular shape between the capseal body 39-1 and the compressed portion 39-5. The concave channels 39-4 may be formed on both surfaces of the capseal 39, respectively. Of course, the concave channel 39-4 may be formed only on one surface of the capseal 39. When the protruding rib 39-7 of the compressed portion 39-5, which will be described below, is deformed, the deformed portion of the protruding rib 39-7 is pushed into the concave channel 39-4 and is positioned. It can be.

A compressed portion 39-5 may be formed surrounding the edge of the capseal 39. The compressed portion 39-5 may be formed such that the capseal 39 protrudes from both surfaces. The compression portion 39-5 has a protruding rib 39-7 that is formed to protrude relatively. The protruding rib 39-7 may have an overall ring shape. One pair of protruding ribs 39-7 may be formed on one surface of the capseal 39, and another pair may be formed on the other surface. Alternatively, the pair of protruding ribs 39-7 may be formed only on one surface of the capseal 39.

A flat area of a predetermined width may be formed between the pair of protruding ribs 39-7. The thickness of the planar area located between the protruding ribs 39-7 may be thicker than that of the capsie body 39-1. The protruding ribs 39-7 may be pressed and pushed into the area between the pair of protruding ribs 39-7.

In the capseal 39, between the thickness (F) of the capseal body (39-1) and the thickness (E) between the protruding ribs (39-7) in the compressed portion (39-5), There is a relationship. That is, the thickness of the F section compared to the E section can be dimensioned to be about 30% to 40%. In addition, the concave channel 39-4 serves as a kind of escape space, and must have a volume that can accommodate about 25% to 30% of the amount of compression of the protruding rib 39-7.

In addition, the degree to which the area between the compression portion 39-5 and the protruding rib 39-7 is compressed relative to the amount by which the protruding rib 39-7 is compressed is between 45% and 55%. It's good. That is, the protruding rib 39-7 is mainly compressed in the compression portion 39-5, and the area between the compression portion 39-5 and the protruding rib 39-7 is the protrusion rib 39-7. About 45% to 55% of what is compressed is compressed.

When the cap seal 39 having the above configuration is mounted in close contact with the shell housing 24, as can be seen in the enlarged view of FIG. 12, the compression portion 39-5 Overlapping with the shell housing 24 and the cap 38, that is, as it is compressed, the spokes of the compressed portion 39-5 may be pushed and come into close contact with the cap 38 and the inner surface of the shell internal space 32. In this process, part of the flesh pushed from the compressed portion 39-5 enters the gap between the protrusions 38' of the cap 38, forming a cap seal ( Part of 39) is filled.

Next, the first ground contact 40 may be installed within the shell inner space 32 of the shell housing 24. The first ground contact 40 may perform an electrical connection for grounding the shell housing 24 and the second connector 60. The first ground contact 40 may be made of a conductive metal material. The first ground contact 40 may be made in a cylindrical shape.

A plurality of contact levers 42 may be formed on the first ground contact 40. The contact lever 42 is made in a cantilever shape and may be capable of a certain amount of elastic deformation. The extension direction of the contact lever 42 is the longitudinal direction of the first ground contact 40. In other words, the contact lever 42 may extend in the direction of coupling and separating the first connector 10 and the second connector 60. An elastic contact protrusion 42' may be formed at the tip of the contact lever 42.

The contact lever 42 may be regulated by the inner surface of the connector 30 of the shell housing 24. This is well depicted in Figure 7. When the contact lever 42 contacts the outer surface of the second ground contact 66 and undergoes elastic deformation, the degree of elastic deformation is regulated by the inner surface of the connection pipe 30.

The first ground contact 40 may have a plurality of spacer protrusions 44. The spacer protrusion 44 is designed to ensure that there is no gap between it and the second ground contact 66, which will be explained below. The spacer protrusions 44 may be formed in plural numbers. The spacer protrusion 44 may be formed to protrude inward from the inner surface of the first ground contact 40. The spacer protrusion 44 may be located closer to one end of the first ground contact 40 than to the elastic contact protrusion 42'. In other words, the spacer protrusion 44 may be located at a position moved toward the second connector 60 relative to the elastic contact protrusion 42'. The spacer protrusion 44 prevents a gap from occurring between the second ground contact 66 and prevents vibration due to flow.

The first ground contact 40 does not necessarily have to be used. Instead of the first ground contact 40, for example, the connector 30 of the shell housing 24 may be used. The contact lever 42 may be provided on the connector 30 to directly perform ground connection.

An inner housing 46 may be installed in the shell inner space 32 of the shell housing 24. The inner housing 46 may be made of an insulating material. The inner housing 46 can perform insulation between the first terminal 50 and the shell housing 24, which will be described below. The shape and size of the inner housing 46 may be designed to fit into the inner space 32 of the shell housing 24. A terminal seating space 48 may be formed by penetrating the inner housing 46 back and forth. The terminal seating space 48 may also have a 'T' shape or an almost 'L' shape.

The first terminal 50 may be made of a conductive metal material. The terminal body 52 may form the skeleton of the first terminal 50. At the tip of the terminal body 52, there may be a first coupling portion 54 that is coupled to the second terminal 64 of the second connector 60 to perform signal connection. The first coupling portion 54 may have any shape as long as it can be coupled to the second terminal 64. There may be a second coupling portion 56 at the rear end of the terminal body 52. The second coupling portion 56 may be shaped so that the cable connector 58, which will be described below, can be press-fitted. However, the second coupling portion 56 may have any shape as long as it can be coupled to the core wire 22' of the cable 22.

There is a cable connector 58 to be coupled to the second coupling portion 56 of the first terminal 50. The cable connector 58 may have a cylindrical shape in this embodiment. The core wire 22' of the cable 22 may be connected to the cable connector 58 by being compressed. With the cable 22 connected to the cable connector 58, it can be coupled to the second coupling portion 56 to perform a signal connection. The cable connector 58 may be made of a conductive metal material.

Meanwhile, the configuration of the second connector 60, which combines with the first connector 10 to make an electrical connection and forms a connector assembly, will be described with reference to FIG. 4. For convenience, Figure 4 schematically shows the configuration of the second connector 60.

The second housing 62 can form the exterior and framework of the second connector 60. The second housing 62 may be made of an insulating material. The second housing 62 may be made of insulating synthetic resin. A portion of the second housing 62 may enter the penetration space 12 of the first housing 11.

A second internal space 63 may be formed inside the second housing 62 into which a portion of the first connector 10 is inserted. The part of the first connector 10 inserted into the second internal space 63 is a part of the terminal unit 20. The second internal space 63 may be opened toward where the first connector 10 is inserted. A second terminal 64 may be installed within the second internal space 63. The second terminal 64 is combined with the first terminal 50 to make an electrical connection.

A second ground contact 66 may be installed in the second internal space 63 of the second housing 62. The second ground contact 66 can be inserted into the first ground contact 40 to make a ground connection. The configuration for the second ground contact 66 to perform the grounding function within the second housing 62 has been omitted for convenience. In the drawing, an unexplained reference numeral 68 is a fastening jaw on which the fastening lever 16 of the first housing 11 is hung.

Hereinafter, the use of the connector according to the present invention having the above-described configuration will be described in detail.

In the present invention, the terminal unit 20 is mounted on the first housing 11 to form a first connector 10, and the first connector 10 can transmit signals by combining with the second connector. . Here, the first housing 11 can be changed to have a different key code, and the terminal unit 20 can be used in combination with various other second connectors 60 using the same one.

When the first connector 10 and the second connector 60 are combined, the connector 30 on which the seal 35 is seated in the terminal unit 20 shown in FIG. 9 is connected to the second connector ( It enters the second internal space 63 of 60). In the process of entering the connector 30 into the second internal space 63 of the second connector 60, the outer diameter of the step 34' at the tip is smaller than the inner diameter of the second internal space 63, The distal end of the connecting pipe 30 can be relatively easily inserted into the second internal space 63.

At this time, the seal 35 adjacent to the step 34' can also relatively easily enter the second internal space 63. As can be seen in the drawings, the seal 35 has an outer diameter larger than the step 34', so although it is in close contact with the inner surface of the second internal space 63, it is not located within the seal seating portion 34. Since the seal 35 is seated, there is no case where the seal 35 is pushed back. Therefore, when the seal 35 is completely coupled to the first connector 10 and the second connector 60, defects such as being folded do not occur.

Meanwhile, when the connection pipe 30 completely enters the inside of the second internal space 63, the overlap portion 36 is at the entrance of the second internal space 63, as can be seen in FIG. 4. On the inside, it overlaps and adheres to the inner surface of the second internal space 63. At this time, the step 34' at the distal end of the connection pipe 30 goes further inward than the midpoint M in the longitudinal direction of the second internal space 63.

In this way, the overlap portion 36 is press-fitted and adhered to the inner surface of the second internal space 63, and the seal 35 is also formed at the midpoint M in the longitudinal direction of the second internal space 63. Since it is in close contact with the inner surface of the terminal unit 63, the portion including the connector 30 of the terminal unit 20 can be firmly fixed to the second internal space 63. In other words, the first connector 10, especially the terminal unit 20, is firmly fixed so that it does not move relative to the second connector 60 even if an external force is applied to the terminal unit 20.

Additionally, the spacer protrusion 44 prevents a gap from occurring between the first ground contact 40 and the second ground contact 66. Accordingly, vibration due to relative movement does not occur between the first ground contact 40 and the second ground contact 66.

Meanwhile, the cap 38 closes the shell internal space 32 formed inside the shell housing 24 at the rear portion of the shell housing 24. The cap 38 is press-fitted into the shell inner space 32, and the cap seal 39 is positioned between the shell housing 24 and the cap 38 to firmly maintain the cap 38 in the mounted state. will be maintained.

Here, the thickness (E) of the compressed portion (39-5) of the cap (38) is formed to be relatively thick compared to the thickness (F) of the capseal body (39-1), so that the compressed portion (39-5) of the cap (38) is formed to be relatively thick. Although the portion (39-5) is compressed, there is a lot of room for the thickness of the compressed portion (39-5) to change even if the environment inside the shell inner space (32) changes, so the mounting state of the cap (38) is maintained. It can be maintained firmly. In particular, the concave channel 39-4 in the connecting neck 39-3 can greatly affect the change in compression amount of the compression portion 39-5.

In the above, even though all the components constituting the embodiment according to the present invention have been described as being combined or operated in combination, the present invention is not necessarily limited to this embodiment. That is, as long as it is within the scope of the purpose of the present invention, all of the components may be operated by selectively combining one or more of them.
