Utility Model Content

[0003] The purpose of the present application is to overcome the above-mentioned defects or problems existing in the background technology and to provide a relay, the matching gaps between the components of the housing of which can have a waterproof function.

[0004] In order to achieve the above purpose, the following technical solutions are adopted:

[0005] The first technical solution relates to a relay, which includes a shell and a first sealing component. The shell includes a housing and a connector. The housing is provided with a first wall. The first wall is provided with a first opening along a first direction. The connector is fixed to the housing and covers the first opening. The connector cooperates with the housing to form a first sealing groove. The first sealing groove is at least partially formed by the outer wall of the first wall and the connector. The connector shields the first sealing groove along a first direction. The first sealing component is located in the first sealing groove to seal the matching gap between the housing and the connector.

[0006] The second technical solution is based on the first technical solution, wherein the first sealing groove is arranged around the connector.

[0007] The third technical solution is based on the second technical solution, wherein the first sealing member is a sealing ring placed in the first sealing groove.

[0008] The fourth technical solution is based on the second technical solution, wherein the first sealing member is formed by solidifying the sealing material injected into the first sealing groove.

[0009] The fifth technical solution is based on the fourth technical solution, wherein the connector includes a body and a first flange, the first flange protrudes from the body perpendicular to the first direction, and the first sealing groove is formed between the outer wall of the first wall and the first flange.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the connector also includes a second flange, the second flange protrudes from the body perpendicular to the first direction, the first flange and the second flange are arranged along the first direction, a slot is formed between the first flange and the second flange, and the slot is plugged into the first wall.

[0011] The seventh technical solution is based on any one of the first to third technical solutions, and it also includes a second sealing member. The outer shell also includes a cover body. The shell is provided with a second opening along a second direction perpendicular to the first direction. The cover body covers the second opening. A second sealing groove is formed between the cover body and the shell. The second sealing member is formed by solidifying the sealing material injected into the second sealing groove.

[0012] The eighth technical solution is based on any one of the fourth to sixth technical solutions, and it also includes a second sealing member. The outer shell also includes a cover body. The shell is provided with a second opening along a second direction perpendicular to the first direction. The cover body is covered on the second opening. A second sealing groove is formed between the cover body and the shell. The second sealing member is formed by solidifying the sealing material injected into the second sealing groove.

[0013] The ninth technical solution is based on the eighth technical solution, wherein the second sealing groove is communicated with the first sealing groove, and the second sealing member is connected with the first sealing member as a whole.

[0014] The tenth technical solution is based on the first technical solution, and further includes a relay body, a signal terminal and a load terminal. The relay body is accommodated in a housing and includes a magnetic circuit part and a contact part. The magnetic circuit part includes a coil assembly. The signal terminal is electrically connected to the coil assembly and passes through the connector along a first direction and extends out of the housing. The load terminal is electrically connected to the contact part, and the load terminal is fixed relative to the housing and extends out of the housing.

[0015] Compared with the prior art, the above solution has the following beneficial effects:

[0016] In the first technical solution, the first seal is located in the first seal groove formed by the connector and the housing, so that the gap between the housing and the connector can be sealed, so that the housing and the connector have a waterproof function. The connector cover is arranged at the first opening and shields the first seal groove along the first direction. Therefore, when the user uses the function of the front side of the connector (for example, when plugging the control terminal with the signal terminal or pulling the control terminal out of the signal terminal), it is not easy to scratch the first seal. In addition, when the connector is located at the front and needs to be exposed to light for a long time, since the first seal is not visible in the opening direction of the first opening, the first seal is not easy to change color due to light and affect the appearance.

[0017] In the fourth technical solution, the first sealing groove is at least partially formed by the outer wall of the first wall and the connector, so the first sealing groove is at least partially exposed outside the housing, so the sealing material can be injected into the first sealing groove. The first sealing groove is arranged around the connector, so the sealing material can flow in the first sealing groove and surround the connector, and the first sealing seal is formed after the sealing material solidifies, which can have a better waterproof effect.

[0018] In the fifth technical solution, the first sealing groove is formed between the outer wall of the first wall and the first flange, so the first sealing groove is exposed as a whole in the outer shell. The sealing material can be selectively injected into the first sealing groove along two directions facing each other, and the two injected sealing materials are connected to each other to form a first seal, which can ensure the waterproof effect of the first seal.

[0019] In the sixth technical solution, the slot is plugged into the first wall, which is a specific implementation method of fixing the connector to the shell. Since the connector is plugged into the shell, the connector assembly efficiency is higher. In addition, the plugging and matching of the connector and the first wall makes the gap between the connector and the shell more tortuous, which helps to improve the sealing effect.

[0020] In the seventh and eighth technical solutions, by providing the second opening and the cover body, it is easier to insert the relay body into the housing.

[0021] In the ninth technical solution, the second sealing groove is connected to the first sealing groove, and the second sealing member is connected to the first sealing member as a whole, so all the matching gaps between the various components of the housing can be sealed as a whole, which has a better waterproof effect.

[0045] like Figure 1 As shown, the housing 2 includes a shell 21 , a connector 22 and a cover 23 .

[0046] See also Figure 3 , Figure 3 The housing 21 is shown. Figure 3As shown, the shell 21 is provided with a cavity, which is surrounded by a bottom wall and a plurality of side walls, one of which is a first wall 211, and the first wall 211 is perpendicular to the first direction Y, and the first direction Y is the front-to-back direction. A first opening 212 is provided on the first wall 211 along the first direction Y. The shell 21 is also provided with a second opening 213 along the second direction Z, and the second direction Z is perpendicular to the first direction Y. The second opening 213 is located at the upper part of the shell 21. In this embodiment, the first opening 212 is connected with the second opening 213. A supporting surface 214 is provided on each side wall of the shell 21, and a retaining wall 215 is formed on the outer side of the supporting surface 214, and the upper surface of the retaining wall 215 is higher than the supporting surface 214.

[0047] See also Figure 4 , Figure 4 A connector 22 is shown. Figure 4 As shown, the connector 22 includes a body 221, a first flange 222 and a second flange 223. The first flange 222 and the second flange 223 protrude from the body 221 perpendicularly to the first direction Y. The first flange 222 and the second flange 223 are arranged along the first direction Y, with the first flange 222 at the front and the second flange 223 at the rear. The first flange 222 is provided with an inclined surface facing the second flange 223. A slot 224 is formed between the first flange 222 and the second flange 223. The slot 224 is adapted to cooperate with the slot of the first wall 211.

[0048] See also Figure 5 , Figure 5 The cover 23 is shown. Figure 5 As shown, the cover body 23 is in the shape of a sheet.

[0049] See also Figure 5 and Figure 6 , Figure 5 and Figure 6 The housing 2 is shown. Figure 5 and Figure 6 As shown, the connector 22 is plugged into the first wall 211 along the second direction Z, so that the slot 224 is plugged and matched with the first wall 211, and the connector 22 is fixed to the housing 21 and covers the first opening 212. After the connector 22 is plugged into place, the outer wall of the first wall 211 and the first flange 222 cooperate to form a first sealing groove 25, and the first sealing groove 25 surrounds the connector 22. In this embodiment, the first sealing groove 25 is formed by the inclined surface of the first flange 222 facing the second flange 223 and the outer wall of the first wall 211. The connector 22 shields the first sealing groove 25 along the first direction. The cover body 23 covers the second opening 213 and is supported by the support surface 214. A second sealing groove 26 is formed between the cover body 23 and the retaining wall 215, and the second sealing groove 26 surrounds the cover body 23. In this embodiment, the second sealing groove 26 is connected to the first sealing groove 25.

[0050] See also Figure 2 , Figure 2 FIG. 3 shows the relay body 3 in this embodiment. Figure 2 As shown, the relay body 3 is accommodated in the housing 21. The relay body 3 includes a magnetic circuit part and a contact part. The magnetic circuit part includes a coil assembly 31 and an armature assembly, and the contact part includes a moving contact and a stationary contact. The coil assembly 31 receives a control signal and changes the magnetic field based on the control signal to drive the armature assembly to rotate or move linearly and drive the moving contact to move to close or open with the stationary contact.

[0051] See also Figure 2 , Figure 2 The signal terminal 4 in this embodiment is shown. Figure 2 As shown, the signal terminal 4 is electrically connected to the coil assembly 31 and extends out of the housing 2 along the first direction Y through the connector 22 .

[0052] See also Figure 1 , Figure 1 FIG. 2 shows a load terminal 5 in this embodiment. The load terminal 5 is electrically connected to the contact portion. Figure 1 As shown, the load terminal 5 is fixed relative to the housing 2 and protrudes from the housing 2 .

[0053] See also Figure 1 , Figure 1 The first seal 6 and the second seal 7 in this embodiment are shown. In this embodiment, the first seal 6 is formed by solidifying the sealing material injected into the first sealing groove 25. The first seal is used to seal the fitting gap between the housing 21 and the connector 22. In this embodiment, the sealing material has fluidity and is suitable for solidification. Specifically, the sealing material can be a polymer material such as epoxy resin. The second seal 7 is formed by solidifying the sealing material injected into the second seal 26. The second seal 7 is used to seal the fitting gap between the housing 21 and the cover body 23. Since the first sealing groove 25 is connected to the second sealing groove 26, in this embodiment, the first seal 6 and the second seal 7 are connected as a whole.

[0054] The assembly steps of the relay 1 in this embodiment are as follows: first, the relay body 3 and the load terminal 5 are installed in the housing 21, and the load terminal 5 is electrically connected to the contact part; then the signal terminal 4 is installed on the connector 22, so that the signal terminal 4 passes through the connector 22 along the first direction X; then, the connector 22 is plugged into the first wall 211 along the second direction Z, so that the slot 224 is plugged into the first wall 221, and the signal terminal 4 is electrically connected to the coil assembly 31; then, the cover body 23 is covered on the second opening 213, so that the support surface 2 14 supports the cover body 23 along the second direction Z; then, injects the sealing material into the upward notch of the first sealing groove 25 and the second sealing groove 26 along the second direction Z, and makes the sealing material injected into the first sealing groove 25 flow to both sides along the third direction X; then, after the sealing material solidifies, flips the intermediate body 180 degrees, and injects the sealing material into the downward notch of the first sealing groove 25, and makes the sealing material injected into the first sealing groove 25 flow to both sides along the third direction X and connect with the sealing material injected last time, thereby completing the assembly of the relay 1.

[0055] In this embodiment, the first seal 6 is located in the first seal groove 25 formed by the connector 22 and the housing 21, so that the clearance between the housing 21 and the connector 22 can be sealed, so that the housing 21 and the connector 22 have a waterproof function. The connector 22 covers the first opening 212 and shields the first seal groove 25 along the first direction Y. Therefore, when the user uses the function of the front of the connector 22 (for example, when plugging the control terminal with the signal terminal 5 or pulling the control terminal out of the signal terminal 5), it is not easy to scratch the first seal 6. In addition, when the connector 22 is located in the front and needs to be exposed to light for a long time, since the first seal 6 is not visible in the opening direction of the first opening 212, the first seal 6 is not easy to change color due to light and affect the appearance.

[0056] In this embodiment, the first sealing groove 25 is formed between the outer wall of the first wall 211 and the first flange 222, so the first sealing groove 25 is exposed as a whole outside the housing 2, so the sealing material can be injected into the first sealing groove 25 in two directions facing each other, and the first sealing groove 25 is arranged around the connector 22, so the sealing material can be injected into the first sealing groove 25 in two directions facing each other, and the two injected sealing materials are connected to each other to form the first sealing member 6. The first sealing member 6 is formed by solidifying the sealing material, which can ensure a better waterproof effect.

[0057] In this embodiment, the slot 224 is plugged into the first wall 211, which is a specific implementation of the connector 22 being fixed to the housing 31. Since the connector 22 is plugged into the housing 21, the assembly efficiency of the connector 22 is higher. In addition, the connector 22 is plugged into the first wall 211, so that the gap between the connector 22 and the housing 21 is more tortuous, which helps to improve the sealing effect.

[0058] In this embodiment, by providing the second opening 213 and the cover 23 , it is easier to insert the relay body 3 into the housing 21 .

[0059] In this embodiment, the second sealing groove 26 is connected to the first sealing groove 25, and the second sealing member 7 is connected to the first sealing member 6 as a whole, so all the matching gaps between the components of the housing 2 can be sealed as a whole, with a better waterproof effect.

[0060] Embodiment 2

[0061] See also Figures 7 to 9 . Figures 7 to 9 The relay 1 in the second embodiment is shown. Figures 7 to 9 As shown, the difference between the relay 1 in this embodiment and the first embodiment is that the outer edge of the body 221 of the connector 22 is provided with a third sealing groove 27, the connector 22 is no longer provided with a second flange 223, and the connector 22 is plugged into the first wall 211 along the first direction Y. The first sealing ring 8 is placed in the third sealing groove 27, and when the connector 22 is plugged into the first wall 211, the first sealing ring 8 abuts against the first wall 211 to form the side wall of the first opening 212. In this embodiment, the first sealing groove 25 and the second sealing groove 26 are not connected, so the first sealing member 6 and the second sealing member 7 are no longer connected as a whole. The electrical connection relationship between the relay body 3, the signal terminal 4 and the load terminal 5 in this embodiment is the same as that in the first embodiment.

[0062] The relay 1 in the second embodiment can also have a good waterproof effect.

[0063] Embodiment 3

[0064] See also Figures 10 to 12 . Figures 10 to 12 The relay 1 in the third embodiment is shown. Figures 10 to 12 As shown, the only difference between the relay 1 in this embodiment and the second embodiment is that the first sealing member 6 is no longer formed by injecting a sealing material into the first sealing groove 26, but is a sealing ring placed in the first sealing groove 25. When the connector 22 is plugged into the first wall 211, the first sealing member 6 presses against the outer wall of the first wall 211 along the first direction Y.

[0065] The relay 1 in the third embodiment can also have a certain waterproof effect.

[0066] The above specification and description of the embodiments are used to explain the protection scope of the present application, but do not constitute a limitation on the protection scope of the present application.
