Description

Technical Field

[0002] In the power supply systems of modern electronic devices, connectors, as key interface components for current and signal transmission, directly determine the power supply efficiency and operational stability of the equipment due to their assembly compatibility, positioning accuracy, and terminal fixation reliability. Currently, most connectors on the market adopt a single structural design or fixed assembly method, which has the following significant drawbacks in practical applications:

[0031] Furthermore, both the bottom surfaces of the first and second housings are provided with multiple positioning posts.

[0032] The beneficial effects of this utility model are:

[0033] High assembly flexibility: Through the snap-fit ​​mechanism of bidirectional positioning strips and positioning slots, rapid assembly and disassembly of individual connector components can be achieved. Different assembly methods can be selected according to the number of power supply paths of external devices and installation space requirements, adapting to the power supply scenarios of various electronic devices and reducing equipment adaptation costs. High positioning accuracy: The use of dual vertical positioning strips (positioning strip one + positioning strip two) and positioning slots (positioning slot one + positioning slot two) effectively limits the horizontal offset and vertical misalignment during the assembly of two components compared to the traditional single positioning structure, ensuring accurate docking of terminal modules and avoiding poor contact caused by positioning deviations.

[0034] The terminals are securely fixed: The fastener uses a triple fixing structure of "snap-fitting slot", "positioning block" and "positioning pin" to restrict the displacement of the terminal module from three directions: front and back, left and right, and up and down. Even in an environment with long-term equipment vibration, it can prevent the terminals from loosening, ensure stable conductivity, and reduce the risk of short circuit.

[0035] Strong anti-interference capability: The horizontal partition plate of the first segmentation positioning plate and the "vertical + vertical" partition plate of the second segmentation positioning plate can clearly separate each terminal group, reduce electromagnetic interference between different terminal groups, especially in high-frequency power supply scenarios, which can effectively reduce voltage fluctuations and improve power supply stability and equipment operation accuracy.

[0036] Stable installation and docking: The positioning posts on the bottom surface of the first and second housings cooperate with the positioning holes of the external equipment to ensure that the connector is installed firmly as a whole; at the same time, the guide key and locking structure in the insertion cavity can achieve precise guidance and locking with the external mating connector, preventing it from falling off after docking.

[0057] This utility model embodiment provides a connector assembly structure, including a first connector assembly 10 and a second connector assembly 20. The two assemblies are detachably assembled by engaging with positioning strips and positioning slots on their side walls. The specific structure is as follows:

[0058] First connector assembly 10:

[0059] The first connector assembly 10 includes a first housing 11, a first terminal module 12, a first segmentation positioning plate, and a first fixing member 14. The first terminal module 12, the first segmentation positioning plate, and the first fixing member 14 are all assembled in the first housing 11. The structure and assembly relationship of each component are as follows:

[0060] The first housing 11 has a first insertion portion 111 (near the insertion end) and a first fixing base 112 (away from the insertion end) arranged sequentially along the horizontal insertion direction (i.e., the direction of mating with the external mating connector). Two positioning posts 118 are provided on the bottom surface of the first housing 11 for engaging with the positioning holes of external devices to achieve overall connector installation and positioning. The first insertion portion 111 has a first insertion cavity 119 for mating with the external mating connector, providing space for terminal mating. The first terminal module 12 is used for current transmission, inserted into the first fixing base 112, with one end (horizontal end 1251) extending into the first insertion cavity 119 and the other end (vertical end 1252) protruding from the first fixing base 112 for connection to an external circuit. A first fixing member 14 is used to firmly fix the first terminal module 12 to the first fixing base 112 to prevent the terminals from loosening.

[0061] A first positioning strip 113 is provided on one side wall of the first housing 11 along the vertical direction, and a second positioning strip 114 is also provided along the vertical direction (i.e., up and down direction) of the first positioning strip 113; a first positioning groove 115 is provided on the other side wall of the first housing 11, and a second positioning groove 116 is also provided along the vertical direction of the first positioning groove 115. The two sets of positioning strips and the two sets of positioning grooves are symmetrically distributed on both sides of the first housing 11, providing a dual positioning reference for precise docking with the second connector assembly 20.

[0062] Connecting arms 117 are respectively provided on both sides of the first fixing base 112. The lower ends of the inner sides (facing the fixing base) of the two connecting arms 117 are provided with mounting slots 1172. The two sides of the first fixing member 14 are provided with engaging parts 141 corresponding to the mounting slots 1172 of the connecting arms 117, and the engaging parts 141 engage with the mounting slots 1172. The lower ends of the connecting arms 117 are also provided with mounting grooves 1173. The two sides of the first fixing member 14 are provided with positioning blocks 142 corresponding to the mounting grooves 1173 of the connecting arms 117, and the positioning blocks 142 are engaged with the mounting grooves 1173. The bottom of the mounting grooves 1173 is provided with positioning pins 1174, and the first fixing member 14 is provided with positioning pin holes 143 corresponding to the positioning pins 1174 of the connecting arms 117, and the positioning pins 1174 are inserted into the positioning pin holes 143. The snap-fit ​​part 141 engages with the assembly slot 1172 to restrict the vertical and horizontal displacement of the first fixing member 14; the positioning block 142 snaps into the assembly groove 1173 to further restrict the front and rear displacement; the positioning pin 1174 is inserted into the positioning pin hole 143 to restrict the displacement of the first fixing member 14. Through the triple fixing structure of "snap-fit ​​+ positioning", a tight fit between the fixing member and the fixing seat is finally achieved, effectively resisting the loosening of the fixing member caused by vehicle vibration and ensuring the stability of the terminal module.

[0063] Each connecting arm 117 has a limiting protrusion 1171 on the outer side of its inner side (the side away from the fixed seat), which serves to limit the movement when the first connector assembly 10 and the second connector assembly 20 are assembled.

[0064] The first terminal module 12 includes a first power terminal group 121, a second power terminal group 122, a third power terminal group 123, and a fourth power terminal group 124. Each of the first power terminal group 121, the second power terminal group 122, and the third power terminal group 123 includes seven conductive terminals 125, while the fourth power terminal group 124 includes two conductive terminals 125.

[0065] All conductive terminals 125 have an L-shaped bent structure, including a horizontal end 1251 for extending into the first insertion cavity 119 and mating with an external mating terminal, and a vertical end 1252 for connecting to an external circuit. In each terminal group, the horizontal ends 1251 of each conductive terminal 125 are arranged in a horizontal direction, and their vertical ends 1252 are arranged in a vertical direction.

[0066] In the fourth power terminal group 124, each conductive terminal 125 has two sets of terminal pins 1253 on its vertical end 1252, which can be used to enhance the connection stability with external circuits and adapt to high current transmission scenarios. In the first power terminal group 121, the second power terminal group 122, and the third power terminal group 123, each conductive terminal 125 has one set of terminal pins 1253 on its vertical end 1252.

[0067] Meanwhile, the first fixing base 112 is also provided with four sets of first plug strips 1121, which correspond one-to-one with the four sets of electrical terminal groups of the first terminal module 12. Each first plug strip 1121 has a first terminal socket 1122 with the same number of conductive terminals 125 in the corresponding electrical terminal group. The first terminal socket 1122 passes through the first fixing base 112 and communicates with the first plug cavity 119, providing an assembly channel for the conductive terminals 125. The first fixing member 14 is provided with a first terminal slot 144 corresponding to the number of terminal pins 1253 in the first terminal module 12.

[0068] During assembly, the horizontal ends 1251 of the conductive terminals 125 of the first terminal module 12 are inserted into the first terminal sockets 1122 and extend into the first insertion cavity 119, and the terminal pins 1253 of the vertical ends 1252 are inserted into and pass through the first terminal slots 144, ensuring that both ends of the conductive terminals 125 are limited and fixed.

[0069] The first dividing positioning plate is disposed on the side of the first fixing base 112 facing the first insertion cavity 119 along the insertion direction, and includes two sets of transverse dividing plates 13. One set of transverse dividing plates 13 is located between the second electrical terminal group 122 and the third electrical terminal group 123, and the other set of transverse dividing plates 13 is located between the third electrical terminal group 123 and the fourth electrical terminal group 124, used to separate different terminal groups and avoid signal / current interference. Three sets of positioning keys 130 are also distributed on the transverse dividing plates 13 of the third electrical terminal group 123 and the fourth electrical terminal group 124 along the insertion direction, further serving as insertion guidance, positioning, and error prevention.

[0070] The first plug-in locking mechanism is located within the first plug-in cavity 119 and is used to achieve precise guidance, positioning, and locking with the external mating connector to prevent it from falling off after mating. The first plug-in locking mechanism includes a first guide key 151, a first guide groove 152, and a first latch 153. The first guide key 151 is located along the axial (horizontal) direction of the first plug-in cavity 119 on the side wall (one on the left side to ensure horizontal guiding accuracy) and the top wall (two on the top wall to ensure vertical guiding accuracy). The first guide groove 152 is located on the top wall of the first plug-in cavity 119, and the first latch 153 (using an elastic snap-fit ​​structure with a certain deformation capability) is located within the first guide groove 152. The two first guide keys 151 on the top wall are symmetrically distributed on both sides of the first latch 153. When mating with an external pairing connector, the first guide key 151 and the first guide groove 152 cooperate with the pairing connector to achieve precise guidance, and the first latch 153 engages with the locking hole of the pairing connector to lock, preventing it from falling off due to vibration or external force after mating.

[0071] Second connector assembly 20:

[0072] The second connector assembly 20 includes a second housing 21, a second terminal module 22, a second segmented positioning plate 23, and a second fixing member 24. The second terminal module 22, the second segmented positioning plate 23, and the second fixing member 24 are all assembled in the second housing 21. Its overall structure is similar to that of the first connector assembly 10, with differences only in the number of terminal groups, the number of terminal sockets, the number of terminal slots, and the structure of the segmented positioning plate, as detailed below:

[0073] The second housing 21 and the first housing 11 are typically made of insulating plastic material and are integrally injection molded. The second housing 21 is provided with a second insertion part and a second fixing seat in sequence along the horizontal insertion direction. The bottom surface is also provided with positioning posts (the same number and distribution as the positioning posts 118 of the first housing 11) for mating with the positioning holes of external equipment. The second insertion part has a second insertion cavity for mating with an external pairing connector.

[0074] A second positioning strip is provided on one side wall of the second housing 21 along the vertical direction, and a second positioning strip is also provided along the vertical direction of the second positioning strip. A second positioning groove is provided on the other side wall of the second housing 21, and a second positioning groove is also provided along the vertical direction of the second positioning groove. The second positioning strip and the second positioning strip are adapted to the first positioning groove 115 and the first positioning groove 116 of the first housing 11, and the second positioning groove and the second positioning groove are adapted to the first positioning strip 113 and the first positioning strip 114 of the first housing 11, providing a structural basis for the bidirectional assembly of the two components.

[0075] The structure of the connecting arms 117, limiting protrusions 1171, assembly slots 1172, assembly grooves 1173 and positioning pins 1174 on both sides of the second fixing seat 24 is the same as that of the first fixing seat 112, ensuring the proper installation of the second fixing component 24.

[0076] The second terminal module 22 is inserted into the second fixed base, with one end (horizontal end) extending into the second insertion cavity and the other end (vertical end) protruding from the second fixed base;

[0077] The second terminal module 22 includes a first power terminal group 221, a second power terminal group 222, a third power terminal group 223, a fourth power terminal group 224, and a fifth power terminal group 225. The first power terminal group 221, the second power terminal group 222, and the third power terminal group 223 each include seven conductive terminals 125, while the fourth power terminal group 224 and the fifth power terminal group 225 each include four conductive terminals 125.

[0078] All conductive terminals in the second terminal module 22 have an L-shaped bent structure, including a horizontal end for inserting into the first insertion cavity and mating with external terminals, and a vertical end for connecting to external circuits. The horizontal ends of the conductive terminals in each terminal group are arranged horizontally, and their vertical ends are arranged vertically. Furthermore, each conductive terminal's vertical end has only one set of terminal pins, differing from the fourth terminal group of the first terminal module 12, to accommodate different current transmission requirements.

[0079] Meanwhile, the second fixing base has the same basic structure as the first fixing base, and is provided with five sets of second plug strips, each corresponding to one of the five sets of electrical terminal groups of the second terminal module 22. Each second plug strip has a second terminal socket with the same number of conductive terminals as the corresponding electrical terminal group. The second terminal socket passes through the second fixing base and communicates with the second plug cavity, providing an assembly channel for the conductive terminals. The structure of the second fixing member 24 is similar to that of the first fixing member 14. Its two sides of the snap-fit ​​part, positioning block and positioning pin hole are adapted to the assembly slot, assembly groove and positioning pin of the second fixing base, respectively. The second fixing member 24 is provided with a second terminal slot corresponding to the number of terminal pins in the second terminal module 22. During assembly, the horizontal end of the conductive terminal of the second terminal module 22 is inserted into the second terminal socket of the second fixing base, and the vertical end of the terminal pin passes through the second terminal slot.

[0080] The second dividing positioning plate 23 is disposed along the insertion direction on the side of the second fixed base facing the second insertion cavity, and includes a longitudinal dividing plate 231 and a vertical dividing plate 232. The longitudinal dividing plate 231 is located between the second electrical terminal group 222 and the third electrical terminal group 223, and the vertical dividing plate 232 is vertically disposed above the longitudinal dividing plate 231. A limiting groove is provided at the end of the vertical dividing plate 232 facing the insertion direction. The limiting groove can cooperate with external connectors to further improve insertion positioning accuracy and connection stability. This structure not only achieves the separation of terminal groups but also enhances the overall structural strength of the dividing positioning plate, preventing deformation after long-term use.

[0081] The structure of the second plug-in locking mechanism is completely the same as that of the first plug-in locking mechanism, including a second guide key, a second guide groove, and a second latch; the second guide key is located on the side wall and top wall of the second plug-in cavity, the second guide groove is located in the middle of the top wall, the second latch is located in the second guide groove, and the second guide key on the top wall is symmetrically distributed on both sides of the second latch; it is used to achieve precise guidance and locking with the external mating connector to ensure docking stability.

[0082] During assembly, the connector of this invention is first assembled by inserting the horizontal ends of each conductive terminal into the terminal sockets of the fixing base, so that the horizontal ends pass through the fixing base and extend into the insertion cavity, and the vertical ends pass through the fixing base. Next, the positioning block of the fixing component is snapped into the assembly groove of the connecting arm, and the positioning pin on the connecting arm is inserted into the positioning pin hole of the fixing component. At this time, the snap-fit ​​parts on both sides of the fixing component are engaged with the assembly slots of the connecting arm, and the terminal pins of the vertical ends of the conductive terminals are inserted one by one into the terminal slots of the fixing component, thus completing the assembly of the connector assembly. Then, the first connector assembly and the second connector assembly are assembled by bidirectional snap-fit ​​of the positioning strip and positioning groove, thus completing the assembly.

[0083] The first connector assembly and the second connector assembly of this utility model achieve precise vertical positioning of the first and second housings through the cooperation of double positioning strips (positioning strip one + positioning strip two) and double positioning grooves (positioning groove one + positioning groove two), effectively avoiding horizontal offset and vertical misalignment after assembly; and after assembly, the terminal modules of the two components can form a multi-channel collaborative transmission structure according to the power supply requirements of external devices, adapting to different current transmission scenarios.

[0084] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
