The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application as detailed in the accompanying claims.

Example 1

Referring to fig. 4 and 5, the connector terminal 12 is used to electrically connect with the compressor terminal 21 extending through the first port 1111.

In the embodiment of the present application, the housing 11 is split to include the first housing portion 111 and the second housing portion 112, which is advantageous for assembling the connector terminal 12. The heat resistance of the first housing portion 111 is higher than that of the second housing portion 112, and the first housing portion 111 is less likely to deform at a high temperature than the second housing portion 112, so that the first port 1111 is provided in the first housing portion 111, and when the connector 10 is connected to the compressor 20, the first housing portion 111 is close to the compressor 20, and the first housing portion 111 has higher heat resistance, so that the internal connector terminals 12 can be prevented from being softened at a high temperature, and the service life of the connector terminals 12 can be prolonged.

The first housing part 111 may be made of a material having high heat resistance, and for example, the first housing part 111 may include at least one of PBT (poly butylene terephthalate ) and GF (glass fiber). In the embodiment of the present application, pbt+30% gf is selected as the first housing portion 111, which is a high temperature resistant fireproof limiting material, so as to prevent the connector terminal 12 from softening during operation.

Referring to fig. 3, the second housing portion 112 may cover the second port 1114 and the connector terminal 12. The second port 1114 is beneficial to the installation of the connector terminal 12 in the housing 11, and the second housing portion 112 covers the second port 1114 and the connector terminal 12, so that the connector terminal 12 and the compressor terminal 21 are wrapped by the housing 11 of the connector 10 when connected, and the problem that the connector terminal 12 and the compressor terminal 21 are easy to strike fire due to the existence of refrigerant near the connector terminal 12 is avoided.

The injection molding housing part is formed through an injection molding process, and the injection molding housing part is connected with the first housing part 111, so that the injection molding housing part and the first housing part 111 are at least in an injection molding integrated structure. Specifically, after the first housing part 111 is molded, at least the first housing part 111 is placed in a mold to participate in the construction of a cavity in which the injection molded housing part is molded, and then a molding material is injected into the cavity to obtain the injection molded housing part.

The glue-pouring shell part is formed through a glue-pouring process, and is connected with the first shell part 111, so that the glue-pouring shell part and the first shell part 111 are of a glue-pouring integrated structure. Specifically, the first housing portion 111 is formed with a molding groove, at least the molding groove participates in the formation of a glue-pouring groove of the glue-pouring housing portion, and then a molding material is injected into the glue-pouring groove to obtain the glue-pouring housing portion.

In summary, the second housing portion 112 can realize an integrally formed structure between the second housing portion 112 and the first housing portion 111, regardless of whether the second housing portion 112 includes an injection molded housing portion or a glue filled housing portion, and compared with the second housing portion 112 and the first housing portion 111 which are independently formed and then assembled, the connection tightness between the second housing portion 112 and the first housing portion 111 can be improved, and the tightness between the second housing portion 112 and the first housing portion 111 can be improved. The second housing 112 of the connector 10 has sealing property with the first housing 111, and the surface of the first housing 111 and the surface of the compressor 20 have sealing property due to the sealing material 13 when the connector 10 is connected with the compressor 20, so that the sealing property of the whole connector 10 can be improved.

The second housing portion 112 may be a sealant, which has a high sealing performance. The second housing portion 112 may or may not have elasticity, and may be flexibly designed according to practical requirements. In the embodiment of the present application, PVC (Polyvinyl chloride ) may be used as the second housing portion 112, which has excellent elasticity and sealing property. The second housing portion 112 may be plastic or silicone, which is not limited thereto.

Referring to fig. 3 and 5, the connector 10 further includes a sealing member 13, wherein the sealing member 13 is located on a side of the first housing portion 111 where the first port 1111 is located and is looped around the first port 1111, and the sealing member 13 is connected to the first housing portion 111. The sealing element 13 is arranged on the first shell part 111, and even if heat on the surface of the compressor 20 is transferred to the sealing element 13 and the first shell part 111, the first shell part 111 is not easy to deform, so that a stable supporting effect can be achieved on the sealing element 13, the sealing performance between the compressor 20 and the connector 10 is ensured, and meanwhile, the connection stability between the compressor 20 and the connector 10 is ensured.

It will be appreciated that opposite sides of the seal 13 may abut the surface of the compressor 20 and the first housing portion 111, respectively, to provide a seal between the surface of the compressor 20 and the first housing portion 111. In an exemplary embodiment, the sealing member 13 may be disposed on the port surface where the first port 1111 of the first housing part 111 is located, and in this case, in order to achieve a reliable connection between the sealing member 13 and the first housing part 111, the sealing member 13 and the first housing part 111 may be connected by an adhesive or the like, so as to avoid the sealing member 13 from falling off.

In another exemplary solution, an annular groove 1113 may be disposed on a side of the first port 1111 of the first housing portion 111, the annular groove 1113 is disposed around the first port 1111, a portion of the seal member 13 may be disposed in the annular groove 1113, and the annular groove 1113 may be disposed to position an installation position of the seal member 13 on the first housing portion 111, to speed up an assembly speed between the seal member 13 and the first housing portion 111, and to constrain the seal member 13, so as to accommodate deformation of the seal member 13 caused by extrusion.

Referring to fig. 3, the portion of the seal 13 located in the annular groove 1113 may be: the seal member 13 includes a first portion 131 and a second portion 132 distributed in the depth direction of the annular groove 1113, the first portion 131 may be located inside the annular groove 1113, and the second portion 132 may be located outside the annular groove 1113. Wherein the second portion 132 outside the annular groove 1113 is deformed when the connector 10 is coupled to the compressor 20, so as to improve the coupling tightness between the connector 10 and the compressor 20.

It is understood that annular groove 1113 may or may not be in communication with first port 1111. In the embodiment of the present application, the annular groove 1113 is not communicated with the first port 1111, so that deformation of the sealing member 13 in the direction of the first port 1111 during extrusion deformation can be avoided, and the installation stability of the sealing member 13 is prevented from being affected. The seal 13 may be attached to the annular groove 1113 by an engagement method, or may be attached to the annular groove 1113 by adhesion or the like, which is not limited thereto.

The sealing element 13 may be any device having sealing properties, such as a sealing ring or the like. In the embodiment of the application, the sealing element 13 is an elastic and high heat-resistant device, wherein the sealing element 13 has elasticity, so that the sealing element 13 can be in a compressed state when the connector 10 is connected with the compressor 20, thereby improving the connection tightness of the connector 10 and the compressor 20; and the sealing element 13 has high heat resistance, so that the damage of the sealing element 13 under the action of the surface heat of the compressor 20 can be avoided, and the service life of the sealing element 13 can be prolonged.

Referring to fig. 3, the connector 10 further includes a cover member covering the second port 1114, and the second housing portion 112 covers the cover member. Under the shielding of the cover, the entry of moisture and dust impurities into the first housing portion 111 can be prevented, affecting the usability of the connector terminal 12. And when the second housing part 112 comprises an injection molding housing part and a glue filling housing part, the molding material of the second housing part 112 cannot pass through the second port 1114 to reach the connector terminal 12 under the shielding of the cover piece, so that the connector terminal 12 is wrapped, and the effective electric connection between the connector terminal 12 and the compressor terminal 21 can be ensured.

Wherein the connector terminal 12 may abut or have a gap between the cover member. Referring to fig. 3, if a gap is formed between the connector terminal 12 and the cover, the connector terminal 12 can be deformed into the gap when inserted into the compressor terminal 21, so that the connector terminal 12 and the compressor terminal 21 are prevented from being damaged by hard insertion.

The covering member may include a cover plate 14, where the cover plate 14 covers the second port 1114 and the connector terminal 12, and the second housing portion 112 covers the cover plate 14.

One of the cover plate 14 and the first housing part 111 may be provided with a limit projection 141, and the other may be provided with a limit groove 1116, the limit projection 141 being located in the limit groove 1116.

It will be appreciated that the cover plate 14 may be provided with a limit projection 141 and the first housing portion 111 may be provided with a limit groove 1116; alternatively, the cover 14 may be provided with a limiting groove 1116, and the first housing 111 may be provided with a limiting protrusion 141, which is not limited thereto. In the embodiment of the present application, the cover 14 is provided with the limiting protrusion 141, and the first housing portion 111 is provided with the limiting groove 1116, so that the cover 14 is relatively thinner, and the limiting protrusion 141 is beneficial to improving the structural strength of the cover 14 compared with the limiting groove 1116.

Referring to fig. 5, the first housing portion 111 is formed with a first cavity 1117 for receiving the connector terminal 12, and the first cavity 1117 may be formed with a second port 1114. The connector 10 may include at least two connector terminals 12, and the first housing part 111 is formed with at least two first chambers 1117 equal in number to the at least two connector terminals 12, each connector terminal 12 being mounted to each first chamber 1117 in one-to-one correspondence. For example, the connector 10 includes two connector terminals 12, and the first housing portion 111 is formed with two first chambers 1117; or the connector 10 includes three connector terminals 12, the first housing portion 111 is formed with three first chambers 1117, etc., which are not limited thereto.

When at least two first chambers 1117 are formed in the first housing 111, the first housing 111 has at least two second ports 1114, and the cover 14 covers all the second ports 1114.

It will be appreciated that when the connector 10 includes at least two connector terminals 12, the compressor 20 includes at least two compressor terminals 21 equal in number to the at least two connector terminals 12, each of the compressor terminals 21 being electrically connected to each of the connector terminals 12 in a one-to-one correspondence. Due to manufacturing errors and the like, the compressor terminals 21 of the compressor 20 are inevitably subject to tolerances, for example, the thickness of the compressor terminals 21, the inclination of the compressor terminals 21, the spacing between adjacent compressor terminals 21, etc., and in order to allow the compressor terminals 21 to be effectively electrically connected to the connector terminals 12 even when there is a tolerance, the connector terminals 12 are movable in the first chamber 1117 in the first direction to adapt to the tolerance of the compressor terminals 21.

Specifically, the connector terminal 12 may have a mating face 121 and a back face 122 opposite the mating face 121, wherein the mating face 121 is for contacting the compressor terminal 21 when the connector terminal 12 is connected to the compressor terminal 21, and the back face 122 is for facing away from the compressor terminal 21 when the connector terminal 12 is connected to the compressor terminal 21. The mating surface 121 can extend in the mating direction of the compressor terminal 21 and the connector terminal 12. The first direction may be perpendicular to the plugging direction of the compressor terminal 21 and the connector terminal 12. The connector terminal 12 moves in the first chamber 1117 along the first direction, which may be: in the first direction, there is a gap between the back surface 122 and the inner wall surface of the first chamber 1117, so that the compressor terminal 21, when inserted into the first chamber 1117 to be in contact with the connector terminal 12, can push the connector terminal 12 to deform toward the gap to fit the tolerance of the compressor terminal 21.

Further, in the first direction, the gap G ₁ between the back surface 122 and the inner wall surface of the first chamber 1117 satisfies: g ₁ is more than or equal to 0.1mm and less than or equal to 2mm. By reasonably defining the gap G1 between the back surface 122 and the inner wall surface of the first chamber 1117 in the first direction, it is possible to avoid not only the space waste caused by the excessive gap but also the damage caused by the hard insertion of the compressor terminal 21 and the connector terminal 12 due to the insufficient gap. Alternatively, G ₁ may be 0.1mm, 0.5mm, 1mm, 1.5mm, 2mm, etc., without limitation.

One of the connector terminal 12 and the compressor terminal 21 may be a male terminal, and the other may be a female terminal. In the embodiment of the application, the connector terminal 12 is a female terminal, the compressor terminal 21 is a male terminal, the connector terminal 12 is formed with a plug hole 123, and at least part of the compressor terminal 21 is inserted into the plug hole 123 and is electrically connected with the connector terminal 12.

Specifically, referring to fig. 6, in an exemplary embodiment, the connector terminal 12 includes a first main board 124, two first bending boards 125 connected to the first main board 124, and two second bending boards 126 connected to the first main board 124, where the first main board 124 extends along the plugging direction, the two first bending boards 125 are located on the same side of the first main board 124 along a direction perpendicular to the board surface of the first main board 124, the two first bending boards 125 are located on opposite sides of the first main board 124 along a direction perpendicular to the plugging direction and parallel to the board surface of the first main board 124, one end of each first bending board 125 is connected to the first main board 124, and the other end of each first bending board 125 is bent and extended in a direction away from the first main board 124; one end of each second bending plate 126 is connected to one end of each first bending plate 125, which faces away from the first main plate 124, the other end of each second bending plate 126 is bent and extended towards the direction close to each other and close to the first main plate 124, each second bending plate 126 and the first main plate 124 are arranged at intervals to form a first plugging hole 1231, two second bending plates 126 are arranged at intervals in a direction perpendicular to the plugging direction and parallel to the plate surface of the first main plate 124 to form a second plugging hole 1232, and the plugging hole 123 comprises a first plugging hole 1231 and a second plugging hole 1232. At this time, the structure of the connector terminal 12 is relatively stable, and is not easy to deform, and the first plug hole 1231 and the second plug hole 1232 can be connected with the compressor terminal 21, so that the connection is more reliable.

In this exemplary embodiment, referring to fig. 6 and 7, the connector 10 includes three connector terminals 12, namely, a first connector terminal 12a, a second connector terminal 12b and a third connector terminal 12c, and the first main boards 124 of the three connector terminals 12 are disposed at an angle to each other. Specifically, in the clockwise direction, an angle θ ₁ between the first main plate 124 of the first connector terminal 12a and the first main plate 124 of the second connector terminal 12b is 20 ° or more and 40 ° or less, and an angle θ ₂ between the first main plate 124 of the first connector terminal 12a and the first main plate 124 of the third connector terminal 12c is 50 ° or more and 70 ° or less. It will be appreciated that the orientation of the compressor terminals 21 corresponds to the orientation of the corresponding connector terminals 12. By the arrangement, a feasible plugging mode exists between the three connector terminals 12 and the three compressor terminals 21, namely, a matching mode exists between the three connector terminals 12 and the three compressor terminals 21, so that the problem of misplacement can be avoided. It is understood that the included angle θ ₁ between the first main plate 124 of the first connector terminal 12a and the first main plate 124 of the second connector terminal 12b may be 20 °, 25 °, 30 °, 35 °, 40 °, and so on, and the included angle θ ₂ between the first main plate 124 of the first connector terminal 12a and the first main plate 124 of the third connector terminal 12c may be 50 °, 55 °, 60 °, 65 °, 70 °, and so on.

Specifically, in another exemplary embodiment, referring to fig. 10 to 16, the connector terminal 12 includes an electrical connection portion 127 for electrically connecting with the compressor terminal 21, the electrical connection portion 127 is formed with a plugging hole 123, the electrical connection portion 127 includes an introduction portion 1271 and a mounting portion 1272 distributed along the plugging direction, and the introduction portion 1271 is closer to the first port 1111 than the mounting portion 1272, that is, the compressor terminal 21 enters the introduction portion 1271 first and then enters the mounting portion 1272 when plugged with the connector terminal 12. Wherein, along the direction from the introducing portion 1271 to the mounting portion 1272, the inner diameter of the introducing portion 1271 is gradually decreased and then gradually increased. As described above, when the compressor terminal 21 is connected to the lead-in portion 1271 of the connector terminal 12, the compressor terminal 21 is restrained by the small diameter of the lead-in portion 1271, and the risk of misinsertion due to mismatching between the compressor 20 and the connector 10 can be avoided. And when the compressor terminal 21 is connected with the mounting portion 1272 of the connector terminal 12, the large caliber of the mounting portion 1272 can accelerate the mounting convenience of the compressor terminal 21 and improve the mounting efficiency. Wherein, along the direction from the introducing portion 1271 to the mounting portion 1272, the inner diameter of the introducing portion 1271 is gradually decreased and then gradually increased. The inside diameter of the lead-in portion 1271 can be smoothly changed, and the smoothness of the connection between the compressor terminal 21 and the connector terminal 12 can be improved.

Example two

Referring to fig. 12 and 16, the difference between the present embodiment and the first embodiment is that when the connector terminal 12 includes the electrical connection portion 127, the covering member may include a blocking portion 128, where the blocking portion 128 is located on a side of the electrical connection portion 127 near the second port 1114, the blocking portion 128 and the electrical connection portion 127 are integrally formed, the second housing portion 112 covers the blocking portion 128, and the blocking portion 128 covers the second port 1114, or the blocking portion 128 covers the plugging hole 123 of the electrical connection portion 127. That is, the cover plate 14 is not required to be additionally provided, and the second port 1114 or the insertion hole 123 can be directly covered by the blocking portion 128 on the connector terminal 12, so that the molding material is prevented from entering the electrical connection portion 127 through the second port 1114 or the insertion hole 123 when the injection molding housing portion or the glue filling housing portion is formed, and the effective electrical connection between the electrical connection portion 127 and the compressor terminal 21 is prevented from being affected.

The blocking part 128 can be formed by partial stamping and bending of the electric connection part 127, so that the processing technology is simple and the material is saved; for example, the blocking portion 128 is formed by punching and bending a material corresponding to a punching hole on the electrical connection portion 127.

One of the electrical connection portion 127 and the first housing portion 111 may be formed with a ridge 1291 and the other may be provided with a groove, the ridge 1291 being located in the groove. The provision of the ridge 1291 and the groove can promote connection reliability between the electrical connection portion 127 and the first housing portion 111. The ribs 1291 may extend along the circumferential direction of the plugging hole 123 or may extend along the axial direction of the plugging hole 123, which is not limited thereto.

The connector terminal 12 may further include a lap joint portion 1292, the lap joint portion 1292 protruding with respect to the electrical connection portion 127, and the lap joint portion 1292 is used for lap joint on the first housing portion 111 so as to be capable of limiting the depth of insertion of the connector terminal 12 into the first housing portion 111, and the like.

Referring to fig. 12 and 15, the connector terminal 12 may further include an insertion portion 1293, and the insertion portion 1293 is inserted into the second housing 112. In this way, when the second housing portion 112 includes an injection molded housing portion and/or a glue filled housing portion, the insert portion 1293 will be integrally connected with the second housing portion 112, so that the mounting stability of the connector terminal 12 in the housing 11 can be improved.

Even if the fitting portion 1293 is fitted into the second housing 112, since the electrical connection portion 127 is located in the first chamber 1117 of the first housing 111 and the back surface 122 of the electrical connection portion 127 has a gap G ₁ with the inner wall surface of the first chamber 1117, the electrical connection portion 127 can still be moved toward the gap to adapt to the tolerance of the compressor terminal 21 when electrically connected to the compressor terminal 21. In addition, the second housing 112 may be provided with a sealant having a certain elasticity, so that the electrical connection portion 127 may be offset.
