[0004] In view of this, the purpose of this utility model is to provide a connector with a double sealing structure, which has better sealing performance and extends the service life of the connector.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A connector, comprising:
[0007] A base and a housing, wherein the housing is fitted over the base and an annular filling cavity is formed between the base and the housing;
[0008] A plurality of sealing rings are fitted onto the base and located between the base and the outer shell;
[0009] A sealing filler is used to fill the filling cavity.
[0010] Furthermore, the inner wall of the outer shell includes a first contact portion and a second contact portion with different diameters to form a first limiting boss that limits the base. The outer wall of the base includes a first connecting portion, a second connecting portion, and a sealing portion with different diameters to form a second limiting boss that contacts the first limiting boss. A plurality of sealing rings are all fitted onto the first connecting portion and in contact with the first contact portion.
[0011] Furthermore, this utility model also includes:
[0012] The limiting member is annular and sleeved on the sealing part. The first contact part is provided with a limiting groove. When the first limiting boss and the second limiting boss are in contact, the limiting member is located in the limiting groove.
[0013] Furthermore, the first connecting part is provided with a plurality of annular grooves for fixing the sealing ring.
[0014] Furthermore, the sealing filler is a sealant.
[0015] Furthermore, the sealing part of this invention is provided with a fixing protrusion.
[0016] Furthermore, in this invention, the fixing protrusion is a spiral structure arranged around the sealing part.
[0017] Furthermore, the base is provided with a plurality of through holes, each of which is into which an insertion hole is inserted. Each insertion hole is provided with at least one anti-retraction protrusion, which is interference-fitted with the through hole.
[0018] Furthermore, the present invention provides an annular collection groove on the insertion hole, which has the same number as the anti-retraction protrusions.

[0033] 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.
[0034] The core of this utility model is to provide a connector that adopts a double sealing structure, which has better sealing performance and extends the service life of the connector.
[0035] Please refer to Figure 1 A connector includes a base 2, a housing 1, a plurality of sealing rings 3 and a sealing filler. The housing 1 is sleeved on the outside of the base 2, and an annular filling cavity 6 is formed between the base 2 and the housing 1. The plurality of sealing rings 3 are all sleeved on the base 2 and located between the base 2 and the housing 1. The sealing filler is filled in the filling cavity 6.
[0036] It should be noted that in this practical embodiment, the inner diameter of the outer shell 1 is larger than that of the base 2, so that a filling cavity 6 is formed between the base 2 and the outer shell 1 at the same end. The filling cavity 6 is sealed by filling it with a sealing filler, wherein the sealing filler is made of an insulating material.
[0037] Optionally, in some embodiments, the number of sealing rings 3 can be designed according to the usage, and two adjacent sealing rings 3 can be arranged in contact with each other. Therefore, after the base 2 and the outer shell 1 cooperate to compress the sealing rings 3, the two sealing rings 3 are simultaneously compressed against each other, thereby increasing the sealing effect of the sealing rings 3.
[0038] In the above embodiment, a reserved gap is reserved between two adjacent sealing rings 3, and the reserved gap is filled with sealing filler. Therefore, after the base 2 and the outer shell 1 cooperate to compress the sealing rings 3, the two sealing rings 3 are simultaneously compressed against each other, compressing the sealing filler and further enhancing the sealing effect.
[0039] In use, the base 2 is inserted into the housing 1. The base 2 supports and fixes the terminals, while the housing 1 fixes and seals the base 2 for easy insertion and removal by the user. Several sealing rings 3 are fitted onto the base 2 and located between the base 2 and the housing 1. That is, by setting several sealing rings 3 on the base 2, when the base 2 is inserted into the housing 1, the sealing rings 3 are located between the base 2 and the housing 1. Therefore, the compression between the base 2 and the housing 1 causes the sealing rings 3 to deform, thereby achieving a seal between the base 2 and the housing 1. At the same time, an annular filling cavity 6 is formed between the base 2 and the housing 1. The filling cavity 6 is filled with sealing filler. The double sealing structure greatly enhances the sealing performance of the connector, and the sealing filler has more effective sealing performance. It more fully fills the space in the sealing filling cavity 6, greatly improving the service life of the connector and the equipment used.
[0040] Please refer to Figure 9In some embodiments, the inner wall of the outer shell 1 includes a first contact portion 101 and a second contact portion 102 with different diameters to form a first limiting boss 103 that limits the base 2. The outer wall of the base 2 includes a first connecting portion 201, a second connecting portion 202, and a sealing portion 204 with different diameters to form a second limiting boss 203 that contacts the first limiting boss 103. Several sealing rings 3 are all fitted onto the first connecting portion 201 and contact the first contact portion 101. That is, the inner wall of the outer shell 1 and the outer wall of the base 2 are both composed of multiple segments with different diameters, wherein the inner wall of the outer shell 1 includes the first contact portion. The outer wall of the base 2 includes a first connecting part 201, a second connecting part 202, and a sealing part 204. The first limiting boss 103 formed between the first contact part 101 and the second contact part 102, and the second limiting boss 203 formed between the first connecting part 201 and the second connecting part 202 cooperate with each other to restrict the movement of the base 2 when it is inserted into the outer shell 1. By adopting a multi-segment structure, the outer shell 1 and the base 2 can be manufactured in one piece, reducing the number of production steps and the overall number of parts of the connector, and providing a more stable limiting function.
[0041] Please continue to refer to this. Figure 1 In some embodiments, a limiting member 4 is also included. The limiting member 4 is annular and is sleeved on the sealing part 204. The first contact part 101 is provided with a limiting groove 104. When the first limiting boss 103 and the second limiting boss 203 are in contact, the limiting member 4 is located in the limiting groove 104. That is, the first contact part 101 is provided with a limiting groove 104 that cooperates with the limiting member 4. The limiting member 4 is sleeved on the sealing part 204. Therefore, when the base 2 is inserted into the outer shell 1, the limiting member 4 moves with the base 2. When the first limiting boss 103 and the second limiting boss 203 are in contact, the limiting member 4 enters the limiting groove 104. At this time, one side of the base 2 is positionally restricted due to the contact of the first limiting boss 103 and the second limiting boss 203, while the other side of the base 2 is positionally restricted due to the limiting member 4 entering the limiting groove 104, thereby completely restricting the base 2 inside the outer shell 1, thereby fixing the base 2.
[0042] Optionally, in some embodiments, the limiting member 4 is a ring structure, so the limiting member 4 can be sleeved on the base 2.
[0043] Optionally, in some embodiments, the limiting member 4 has a notch, thus enabling the limiting member 4 to have a deformable function so that it can be adapted to use with bases 2 of different sizes.
[0044] Optionally, in some embodiments, the limiting member 4 is made of a material with elastic deformation function. Specifically, the limiting member 4 can be made of plastic or metal, such as stainless steel or spring steel, and its thickness can allow it to have a certain deformation function.
[0045] Please refer to Figure 7 In some embodiments, the first connecting part 201 is provided with a plurality of annular grooves 205 for fixing the sealing ring 3. That is, the annular grooves 205 are provided on the outside of the base 2 and are located in the first connecting part 201. The annular grooves 205 are used to fix the sealing ring 3. The diameter of the sealing ring 3 is slightly smaller than the diameter of the first connecting part 201. Therefore, the sealing ring 3 is fitted in the annular grooves 205 to fix the sealing ring 3 and prevent the sealing ring 3 from shifting when the base 2 is inserted into the outer shell 1, which is beneficial to improving the sealing effect of the sealing ring 3.
[0046] Optionally, in some embodiments, the sealing filler is a sealant, that is, the gap between the base 2 and the housing 1 is filled with glue to achieve an effective seal between the base 2 and the housing 1, and the glue can also enhance the strength of the base 2 and the housing 1.
[0047] Optionally, in some embodiments, the sealant may be a quick-drying adhesive, which is then rapidly air-dried and set by irradiation with blue or ultraviolet light after filling.
[0048] In other embodiments, the sealant may be made of silicone rubber, which has higher reliability, a wider temperature range, weather resistance and elasticity.
[0049] Please refer to Figure 6 In some embodiments, the sealing part 204 is provided with a fixing protrusion. That is, by providing a fixing protrusion, the contact area between the sealing part 204 and the sealant is increased, thereby improving the firmness of the sealant in fixing the base 2 and the outer shell 1.
[0050] Optionally, in some embodiments, the fixing protrusion is a spiral structure arranged around the sealing part 204. The fixing protrusion of the spiral structure greatly increases the contact area between the sealant and the base 2, thereby improving the firmness between the base 2 and the outer shell 1.
[0051] In other embodiments, the fixed protrusion is a plurality of boss structures, and the outer shell 1 is provided with auxiliary protrusions that are staggered with the fixed protrusions. Therefore, when the sealant is filled into the filling cavity 6, after the sealant dries, the contact area between the fixed protrusions and the auxiliary protrusions with the sealant is greatly increased, thereby further improving the firmness of the base 2 and the outer shell 1.
[0052] Please refer to Figure 6In some embodiments, the base 2 is provided with a plurality of through holes 206, and an insertion hole 5 is inserted into each of the plurality of through holes 206. The insertion hole 5 is provided with at least one annular anti-retraction protrusion 501. The anti-retraction protrusion 501 is interference-fitted with the through hole 206. Therefore, when the insertion hole 5 is inserted into the through hole 206, the insertion hole 5 is fixed in the through hole 206 by the interference fit between the anti-retraction protrusion 501 and the through hole 206 under the action of friction, thereby achieving effective fixation of the insertion hole 5.
[0053] In the above embodiment, the interference fit between the anti-retraction protrusion 501 and the through hole 206 can ensure the effective sealing of the through hole 206 when the socket 5 is inserted into the through hole 206, further enhancing the sealing performance of the connector.
[0054] Please continue to refer to this. Figure 5 In some embodiments, the insertion hole 5 is provided with annular collection grooves 502, which are the same number as the anti-retraction protrusions 501. The collection grooves 502 can be used to collect debris generated by friction between the anti-retraction protrusions 501 and the sidewall of the through hole 206, thereby ensuring the firmness of the insertion hole 5 within the through hole 206.
[0055] In the above embodiment, the collection groove 502 is located on the side of the anti-retraction protrusion 501 that moves away from the insertion hole 5 into the through hole 206. Therefore, when the insertion hole 5 is inserted into the through hole 206, the debris generated by the friction of the anti-retraction protrusion 501 will enter the collection groove 502.
[0056] Optionally, in some embodiments, the anti-retraction protrusion 501 is frustoconical, and the side of the anti-retraction protrusion 501 with a smaller area faces the side that moves into the through hole 206 of the insertion hole 5, thereby increasing the contact area between the anti-retraction protrusion 501 and the side wall of the through hole 206, and also making it easier for the anti-retraction protrusion 501 to enter the through hole 206.
[0057] Optionally, in some embodiments, after filling the filling cavity 6 with sealant, a sealing end cap is installed on the sealant. The sealing end cap is annular and its width is the same as the width of the filling cavity 6.
[0058] In other words, the key point of this utility model is: adopting a double-sealing form, the base 2 is inserted into the shell 1. The base 2 is used to support and fix the terminals, and the shell 1 is used to fix the base 2 and seal the base 2 to facilitate user insertion and removal. Several sealing rings 3 are all sleeved on the base 2 and located between the base 2 and the shell 1. That is, by setting several sealing rings 3 on the base 2, when the base 2 is inserted into the shell 1, the sealing rings 3 are located between the base 2 and the shell 1. Therefore, the compression between the base 2 and the shell 1 causes the sealing rings 3 to deform, thereby achieving a seal between the base 2 and the shell 1. At the same time, an annular filling cavity 6 is formed between the base 2 and the shell 1. The filling cavity 6 is filled with sealing filler. The double-sealing structure greatly enhances the sealing performance of the connector, and the sealing filler has more effective sealing performance. It more fully fills the space in the sealing filling cavity 6, greatly improving the service life of the connector and the equipment used.
[0059] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0060] The connector provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
