Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a connector and its manufacturing method. Background Technology

[0002] High-voltage connectors, as connecting devices for high-voltage circuits, can be used in the electric vehicle field. A high-voltage connector consists of power terminals, a main body core, and a protective cover. The power terminals are mounted on the main body core, and the protective cover is assembled with the main body core to prevent direct contact between the power terminals or other live parts and the human body. According to the existing assembly sequence, the power terminals should be inserted into the main body core first, and then the protective cover should be placed on top. However, if the operator mistakenly assembles it incorrectly, such as assembling the protective cover with the main body core first, the power terminals will not be able to be assembled, requiring rework. Summary of the Invention

[0003] The purpose of this invention is to provide a connector and its manufacturing method, which solves the problem of power terminals being unable to be assembled due to misinstallation of the protective cover.

[0004] The objective of this invention is achieved through the following technical solution:

[0006] The plastic shell body has a receiving groove, the plastic shell body is provided with a first buckle part, the first buckle part is located outside the receiving groove, the plastic shell body has a slot, and a stop part is provided in the slot, the stop part divides the slot into a first slot and a second slot.

[0007] The protective cover includes a second snap-fit ​​portion, which has a first snap-fit ​​groove and a second snap-fit ​​groove arranged along the height direction of the connector. The first snap-fit ​​portion can be sequentially snapped into the first snap-fit ​​groove and the second snap-fit ​​groove. The protective cover includes an elastic fastening portion, and the stop portion limits the elastic fastening portion to the first snap-fit ​​groove.

[0008] A power terminal is installed in the receiving groove, and the elastic fastening part extends at least partially into the receiving groove. The power terminal can push the elastic fastening part to move away from the receiving groove, so that the elastic fastening part can move from the first slot to the second slot under the action of external force, while the first latching part can be latched into the second latching slot.

[0009] As a further improvement of the present invention, the elastic fastening part includes an elastic part, a retaining part extending vertically from the elastic part, and a hook part extending vertically from the elastic part. The hook part extends at least partially into the receiving groove. The power terminal pushes the hook part to cause the elastic fastening part to undergo elastic deformation, thereby enabling the retaining part to move from the first slot to the second slot under the action of external force to complete the fastening.

[0010] As a further improved technical solution of the present invention, the stop has a through opening, the through opening connects the first card slot and the second card slot, the through opening has a first width, the holding part has a second width, the second width is greater than the first width, and the hook part has a third width, the first width is greater than the third width.

[0011] As a further improvement of the present invention, the baffle includes a first baffle and a second baffle, the first baffle and the second baffle are disposed opposite to each other, and the gap between the first baffle and the second baffle is the passage.

[0012] As a further improved technical solution of the present invention, the holding part includes a first holding part and a second holding part, the first holding part and the second holding part are spaced apart, and the hook part is located between the first holding part and the second holding part.

[0013] As a further improvement of the present invention, the power terminal includes an outer side facing the first slot, and the outer side is capable of abutting against the hook located in the first slot.

[0014] As a further improvement of the present invention, the power terminal includes a base and a folded portion. The folded portion is formed by folding one end of the base toward the mounting direction of the power terminal. The other end of the base is provided with a first bent portion. The first bent portion extends vertically from the base toward the folded portion and has the outer side surface.

[0015] As a further improved technical solution of the present invention, the housing body includes a receiving part located around the receiving groove, and the first snap-fit ​​part is a snap-fit ​​boss protruding from the receiving part. The snap-fit ​​boss has a first inclined surface, which is inclined relative to the installation direction of the protective cover. The installation direction of the protective cover is parallel to the height direction of the connector.

[0016] As a further improved technical solution of the present invention, the receiving part includes a first sidewall, a second sidewall opposite to the first sidewall, and a third sidewall connecting the first sidewall and the second sidewall. The first sidewall and the second sidewall are both provided with the first buckle part, the number of the second buckle parts is equal to the number of the first buckle parts, and the third sidewall is provided with the buckle groove.

[0017] The objective of this invention is also achieved through the following technical solutions:

[0018] A method for manufacturing a connector includes the following steps:

[0019] S1, providing the housing body;

[0020] S2, providing the protective cover, inserting the first snap-fit ​​part of the rubber shell body into the first snap-fit ​​groove of the protective cover, with the elastic fastening part extending into the first snap-fit ​​groove;

[0021] S3, the power terminal is provided, the power terminal is inserted into the receiving groove, the power terminal pushes the elastic fastening part to move away from the receiving groove, and applies external force to the protective cover, thereby causing the elastic fastening part to move from the first slot to the second slot, while the first latching part is engaged in the second latching groove.

[0022] This invention addresses the issue of power terminals being unable to be inserted into the housing body by providing a first and second snap-fit ​​groove on the protective cover. Before the power terminals are inserted into the housing body, the protective cover and the housing body are pre-assembled. Due to the interference between the elastic fastening part and the blocking part, the first snap-fit ​​part of the housing body can only be inserted into the first snap-fit ​​groove, thus reserving space for the power terminals to be inserted. After the power terminals are assembled, the elastic fastening part of the protective cover engages with the second snap-fit ​​groove, so that the first snap-fit ​​part of the housing body is inserted into the second snap-fit ​​groove, thereby achieving the assembly of the housing body, the protective cover, and the power terminals. This solves the problem of power terminals being unable to be assembled due to misinstallation of the protective cover, and the pre-installation of the protective cover on the housing body also solves the problem of missing protective caps.

In this invention, the term "several" means two or more.

[0047] Please refer to Figures 1 to 20 As shown, this invention discloses a connector comprising a housing body 1, a protective cover 2, and power terminals 3. The power terminals 3 are snapped into the housing body 1. The housing body 1 has a first pair of interfaces 10. The protective cover 2 is assembled with the housing body 1 and has a second pair of interfaces 10', with the first pair of interfaces 10' and the second pair of interfaces 10' being opposite each other. By providing the protective cover 2, direct contact between the power terminals 3 and the human body is avoided, thus providing a safety protection function.

[0048] See Figure 6 The housing body 1 has a receiving groove 101, and the power terminal 3 is installed in the receiving groove 101. The housing body 1 includes a receiving part 11, which is located on the periphery of the receiving groove 101.

[0049] The outer shell body 1 and the protective cover 2 are fixedly connected by snap-fit ​​fasteners. See details below. Figure 6 The housing body 1 is provided with a first latching part 111, which is located outside the receiving groove 101. See also Figure 3The protective cover 2 includes a cover body 21 and a second latching part 22 connected to the cover body 21. When the housing body 1 and the protective cover 2 are assembled, the first latching part 111 and the second latching part 22 engage with each other, thereby fixing the housing body 1 and the protective cover 2 together. In the embodiment illustrated in the present invention, the first latching part 111 is a latching boss protruding from the receiving part 11, and the second latching part 22 has a first latching groove 221 and a second latching groove 222 arranged along the height direction of the connector. The first latching groove 221 is located below the second latching groove 222, and the latching boss can sequentially engage with the first latching groove 221 and the second latching groove 222. The latching boss has a first inclined surface 110, which is inclined relative to the installation direction of the protective cover 2. This facilitates the second latching part 22 sliding into the latching groove along the first inclined surface 110. The installation direction of the protective cover 2 is parallel to the height direction of the connector.

[0050] like Figure 5 As shown, the protective cover 2 has a top surface 25, and the second latching part 22 is a spring piece that extends vertically from the cover body 21 in a direction away from the top surface 25. By setting it as a spring piece structure, it is convenient for the first latching part 111 and the second latching part 22 to fasten each other. The second latching groove 222 is closer to the top surface 25 than the first latching groove 221.

[0051] See Figure 7 The housing body 1 includes a first outer shell portion 121 located around the receiving portion 11 and a second outer shell portion 122 connected to the first outer shell portion 121. The second outer shell portion 122 has an insertion channel 1220 communicating with the receiving groove 101, and the power terminal 3 is inserted into the receiving groove 101 through the insertion channel 1220. The first outer shell portion 121 and the second outer shell portion 122 together constitute the outer shell of the housing body 1. In the embodiment illustrated in this application, there are two receiving portions 11, and one housing body 1 may be equipped with two power terminals 3.

[0052] See Figure 7 and Figure 8 The housing body 1 has a slot 102, and a stop 113 is provided in the slot 102, which divides the slot 102 into a first slot 1021 and a second slot 1022. Specifically, the first slot 1021 and the second slot 1022 are arranged along the height direction of the connector, and the second slot 1022 is located below the first slot 1021.

[0053] See Figure 3The protective cover 2 includes an elastic fastening part 23, which at least partially extends into the receiving groove 101. During assembly, the stop 113 restricts the elastic fastening part 23 to the first slot 1021, preventing it from entering the second slot 1022. At this time, the first latching part 111 can only be latched into the first latching groove 221. This state is the pre-assembly state of the protective cover 2 and the housing body 1. During the installation of the power terminal 3 into the receiving groove 101, the elastic fastening part 23 can undergo elastic deformation under force. The power terminal 3 can push the elastic fastening part 23 to move away from the receiving groove 101, thereby allowing the elastic fastening part 23 to move from the first slot 1021 to the second slot 1022 under the action of external force. At the same time, the first latching part 111 can be latched into the second latching groove 222.

[0054] See Figure 4 The elastic fastening part 23 includes an elastic part 231, a retaining part 232 extending vertically from the elastic part 231, and a hook part 233 extending vertically from the elastic part 231. The hook part 233 extends at least partially into the receiving groove 101. During assembly, the power terminal 3 pushes the hook part 233 in the pre-assembled state to cause the elastic fastening part 23 to undergo elastic deformation. After the power terminal 3 is assembled in place, due to the elastic deformation of the elastic fastening part 23, a downward force is applied to the protective cover 2, which can move the retaining part 232 from the first slot 1021 to the second slot 1022, and at the same time, the first latching part 111 is engaged with the second latching groove 222, thus completing the assembly of the power terminal 3, the protective cover 2, and the housing body 1.

[0055] In one implementation, see Figure 10 The stop portion 113 includes a first stop portion 1131 and a second stop portion 1132, which are disposed opposite to each other. A gap exists between the first stop portion 1131 and the second stop portion 1132, which is a through-hole 1130. The through-hole 1130 connects to the first slot 1021 and the second slot 1022. The through-hole 1130 has a first width W1, the holding portion 232 has a second width W2, which is greater than the first width W1, and the hook portion 233 has a third width W3, which is greater than the first width W1. In other words, the hook portion 233 can move freely within the through-hole 1130 and can freely move from the first slot 1021 to the second slot 1022.

[0056] See Figure 7 The main body 1 of the plastic shell is provided with a limiting part 112, which is located within the receiving groove 101. Figure 2 As shown, the power terminal 3 has a groove 30, and a limiting part 112 is installed in the groove 30. The limiting part 112 is provided to prevent the power terminal 3 from retracting. The mounting direction of the power terminal 3 is perpendicular to the mounting direction of the protective cover 3.

[0057] See Figure 9 The receiving section 11 includes a first sidewall 114, a second sidewall 115 opposite to the first sidewall 114, and a third sidewall 116 connecting the first sidewall 114 and the second sidewall 115, wherein the first sidewall 114 and the second sidewall 115 are both perpendicular to the third sidewall 116. The receiving slot 101 includes a space enclosed by the first sidewall 114, the second sidewall 115, and the third sidewall 116.

[0058] The first sidewall 114 and the second sidewall 115 are each provided with a first latching part 111, and the number of second latching parts 22 is equal to the number of first latching parts 111. The third sidewall 116 is provided with a latching groove 102, which is recessed downward from the upper end of the third sidewall 116. The first stop part 1131 and the second stop part 1132 are protrusions extending from the inner walls on both sides of the latching groove 102 into the latching groove 102.

[0059] In the embodiments illustrated in the present invention, see... Figure 7 and Figure 9 The protective cover 2 has a first side groove 1141 recessed on the outer surfaces of both the first side wall 114 and the second side wall 115. A first latching part 111 is located within the first side groove 1141, and the outer end face of the first latching part 111 does not protrude from the first side groove 1141. During assembly, the second latching part 22 of the protective cover 2 is installed in the first side groove 1141. A second side groove 1142 is also recessed on the outer surfaces of the first side wall 114 and the second side wall 115. The protective cover 2 includes two opposing fourth side walls 24, which are installed in the second side groove 1142 to achieve positioning and installation of the protective cover 2 and the housing body 1.

[0060] The limiting portion 112 extends from the first sidewall 114 into the receiving groove 101, or the limiting portion 112 extends from the second sidewall 115 into the receiving groove 101. Specifically, the top surface of the limiting portion 112 is flush with the top surface of the first sidewall 114, or the top surface of the limiting portion 112 is flush with the top surface of the second sidewall 115. That is, the limiting portion 112 is located at the first interface 10 of the housing body 1. See the illustrated embodiment of the present invention. Figure 8 The limiting part 112 has a second inclined surface 1120, which is inclined relative to the mounting direction of the power terminal 3.

[0061] See Figure 4 The elastic part 231 is connected to the cover 21. The retaining part 232 includes a first retaining part 2321 and a second retaining part 2322, which are spaced apart. The hook part 233 is located between the first retaining part 2321 and the second retaining part 2322.

[0062] See Figure 15 and Figure 16The retaining part 232 does not extend into the receiving groove 101. After the protective cover 2 is assembled with the housing body 1, the first inner surface 230 of the retaining part 232 is located within the retaining groove 102, and the first inner surface 230 of the retaining part 232 does not extend beyond the second inner surface 1133 of the stop part 113. That is to say, the retaining part 232 does not penetrate deep into the receiving groove 101, thereby avoiding interference between the retaining part 232 and the power terminal 3. The first inner surface 230 of the retaining part 232 includes the inner surface of the first retaining part 2321 and the inner surface of the second retaining part 2322; the second inner surface 1133 of the stop part 113 includes the inner surface of the first stop part 1131 and the inner surface of the second stop part 1132.

[0063] See Figure 17 and Figure 18 The power terminal 3 includes an outer surface 3110 facing the first slot 1021, and the outer surface 3110 can abut against the hook portion 233 located in the first slot 1021. After the housing body 1, the protective cover 2 and the power terminal 3 are assembled, the hook portion 233 is located between the first bent portion 311 and the second bent portion 312, and the hook portion 233 does not interfere with the power terminal 3.

[0064] See Figure 19 The power terminal 3 includes a base 31 and a folded portion 32, which is folded from one end of the base 31 in the mounting direction of the power terminal 3. The folded portion 32 includes a first folded portion 321 and a second folded portion 322. The first folded portion 321 is folded and fits snugly against the base 31, while the second folded portion 322 is raised relative to the first folded portion 321 away from the base 31, so that the second folded portion 322 does not contact the base 31. The cable contacts the first folded portion 321 to achieve circuit conduction.

[0065] See Figure 19 and Figure 20 The other end of the base 31 is provided with a first bent portion 311 and a second bent portion 312, both of which extend perpendicularly toward the second folded portion 322 relative to the base 31. The second folded portion 322 is provided with a first mounting groove 3221 and a second mounting groove 3222. The first bent portion 311 includes a first mounting portion 3111, and the second bent portion 312 includes a second mounting portion 3121. The first mounting portion 3111 is mounted in the first mounting groove 3221, and the second mounting portion 3121 is mounted in the second mounting groove 3222. The space between the base 31, the second folded portion 322, and the first bent portion 311 forms a third pair of interfaces 300, with the first pair of interfaces 10, the second pair of interfaces 10', and the third pair of interfaces 300 respectively facing each other.

[0066] Both the first mounting part 3111 and the second mounting part 3121 are dovetail-shaped, and both the first mounting groove 3221 and the second mounting groove 3222 are dovetail grooves. This arrangement makes the power terminal 3 structure more stable.

[0067] The first bend 311 is close to the second interface 10' of the body 1 of the housing relative to the second bend 312, and the first bend 311 has an outer side surface 3110.

[0068] In some embodiments, both the housing body 1 and the protective cover 2 are injection molded.

[0069] This invention also discloses a method for manufacturing a connector, comprising the following steps:

[0070] S1, providing the plastic shell body 1;

[0071] S2, a protective cover 2 is provided, and the first snap-fit ​​part 111 of the rubber shell body 1 is snapped into the first snap-fit ​​groove 221 of the protective cover 2;

[0072] S3, provide power terminal 3, insert power terminal 3 into receiving groove 101, power terminal 3 pushes elastic fastening part 23 to move away from receiving groove 101, applies external force to protective cover 2, thereby causing elastic fastening part 23 to move from first slot 1021 to second slot 1022, while first latching part 111 latches into second latching groove 222.

[0073] During assembly, the first pair of interfaces 10 of the housing body 1 face upwards, and the protective cover 2 is fastened to the upper end of the housing body 1. Pre-assembly is performed first. After the power terminals 3 are assembled in place, a downward external force is applied to the protective cover 2 to complete the assembly.

[0074] Specifically, during the process of inserting the power terminal 3 into the receiving groove 101, the hook 233 in the pre-assembled state is pushed to move away from the receiving groove 101. After the power terminal 3 is assembled in place, due to the elastic deformation of the elastic fastening part 23, a downward force is applied to the protective cover 2, which enables the retaining part 232 to engage with the second retaining groove 1022. At the same time, the first retaining part 111 is engaged with the second retaining groove 222, thus completing the assembly of the power terminal 3, the protective cover 2 and the housing body 1. Figure 13 and Figure 14 An assembly diagram of the housing body 1, protective cover 2, and power terminal 3 is shown.

[0075] This invention provides a first snap-fit ​​groove 221 and a second snap-fit ​​groove 222 in the protective cover 2. Before the power terminal 3 is inserted into the housing body 1, due to the interference between the elastic fastening part 23 and the stop part 113, the first snap-fit ​​part 111 of the housing body 1 can only be snapped into the first snap-fit ​​groove 221, thereby reserving space for the power terminal 3 to be inserted. This solves the problem that the power terminal 3 cannot be assembled due to the misinstallation of the protective cover 2. Furthermore, the fact that the protective cover 2 is pre-installed on the housing body 1 can also solve the problem of the protective cap being missing.

[0076] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of this specification should be based on those skilled in the art. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present invention. All technical solutions and improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
