[0003] The locked portion in this locking design is integrally formed on the second shell made of plastic material, and its structural strength is poor. When the applied force is too large, it is easy to break, resulting in locking failure. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a first connector, a second connector and a connector combination with reliable locking.

[0005] According to one aspect of the present invention, a first connector is provided, which can be locked with a second connector, and comprises: an insulating base, a first docking cavity is provided on the upper surface of the insulating base, and a second docking cavity is provided on the lower surface of the insulating base; a plurality of first conductive terminals are fixed on the insulating base, the upper ends of the first conductive terminals extend upward into the first docking cavity, and the lower ends of the first conductive terminals extend downward into the second docking cavity; and a metal locking plate is buried in the insulating base, the middle part of the metal locking plate has an opening, the first conductive terminals pass through the opening from top to bottom, and the metal locking plate has a locking mechanism protruding upward on both sides of the opening.

[0007] According to another aspect of the present invention, a connector combination is provided, comprising the first connector as described above and the second connector as described above, wherein the two locking mechanisms of the first connector are correspondingly inserted into the two pivot grooves of the second connector and correspondingly locked with the locking notches of the locking element of the second connector, and the first conductive terminal of the first connector is correspondingly docked with the docking portion of the second conductive terminal of the second connector.

[0008] According to another aspect of the present invention, the present invention provides a connector combination, which includes: a first connector, which includes an insulating base and a plurality of first conductive terminals fixed on the insulating base, the upper surface of the insulating base is provided with a first docking cavity, and the lower surface is provided with a second docking cavity, the first conductive terminal is generally needle-shaped, its upper end protrudes upward from the first docking cavity, and its lower end protrudes downward from the second docking cavity; a second connector, which is correspondingly plugged into the first connector, the second connector includes a terminal seat, a plurality of second conductive terminals fixed on the terminal seat, a cable electrically connected to the second conductive terminal and an outer cover surrounding the outer periphery of the terminal seat; each second conductive terminal has an elastic docking portion, which corresponds to the upper end of the first conductive terminal; and at least one terminal module, which includes a shell and a plurality of third conductive terminals fixed in the shell, the shell is correspondingly inserted into the second docking cavity of the first connector, each third conductive terminal has an elastic docking portion, and the elastic docking portion of the third conductive terminal corresponds to the lower end of the first conductive terminal.

The structural strength of the locking mechanism is good, making the locking combination firm and reliable. In the second connector, the locking spring can be stopped by the locking protrusion, so that the locking element remains in a locked state, and can be easily locked and unlocked.

[0010] The first connector uses a needle-shaped first conductive terminal, and the second conductive terminal and the third conductive terminal are respectively combined with the upper end or the lower end of the first conductive terminal using an elastic docking portion.

Moreover, when the connector combination is in a docking state, the first conductive terminal can achieve reliable docking with the second conductive terminal and the third conductive terminal, thereby improving the quality of current transmission. In addition, a larger current can be transmitted in the same volume, thereby improving transmission efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Although the present invention can be easily embodied in different forms of embodiments, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to that described herein.

[0041] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0042] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the present invention are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indications of these directions also change accordingly.

[0043] The preferred embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of this specification.

[0044] See also Figure 1 and Figure 2 The connector assembly 100 of a preferred embodiment of the present invention is preferably applied to a motor 500. The connector assembly 100 mainly includes a first connector 1 and a second connector 2 matched with the first connector 1. The first connector 1 is mounted on the motor 500 by a plurality of screws 17, and the second connector 2 is correspondingly plugged into the first connector 1, and the second connector 2 has a cable 23 extending outward.

[0045] For ease of description, the direction of the first connector 1 and the second connector 2 close to the motor 500 when in use is defined as "downward", and the direction away from the "downward" end is defined as "upward". In addition, the direction in which the cable 23 of the second connector 2 extends is defined as "rearward", and the other opposite end is defined as "frontward".

[0046] like Figure 2 As shown, the first connector 1 is provided with two locking mechanisms 132 protruding upwards, and the locking mechanism 132 has a locking protrusion 1322. Figures 2 to 4As shown, the second connector 2 is provided with a locking element 25, and the locking element 25 has two locking arms 252. When the first connector 1 and the second connector 2 are plugged together, the locking arms 252 of the locking element 25 can be clamped on the locking protrusion 1322 of the locking mechanism 132 to lock the first connector 1 and the second connector 2.

[0047] See also Figure 5 and Figure 6 The first connector 1 has a plurality of first conductive terminals 12 , and the second connector 2 has a plurality of second conductive terminals 22 . The lower ends of the second conductive terminals 22 are respectively connected to the upper ends of the first conductive terminals 12 .

[0048] Combination Figures 5 to 7 The connector assembly 100 further includes a first terminal module 3 and a second terminal module 3a, and the two terminal modules 3, 3a are plugged into the first connector 1 from the bottom of the first connector 1. The two terminal modules 3, 3a respectively have a plurality of third conductive terminals 32, and the upper ends of the third conductive terminals 32 are respectively connected to the lower ends of the first conductive terminals 12. The lower parts of the two terminal modules 3 are accommodated in the motor 500. Among them, the second terminal module 3a has a plurality of connecting wires 33 extending downward. These connecting wires 33 are accommodated in the motor 500 and are respectively connected to the corresponding electrical ports of the motor 500. The connecting wires of the first terminal module 3 are not shown.

[0049] By correspondingly connecting the first conductive terminals 12 , the second conductive terminals 22 , and the third conductive terminals 32 , electrical signal exchange between the motor 500 and the connector assembly 100 can be achieved, so that the motor 500 can work normally.

[0050] The following is a detailed introduction of each component of the connector assembly 100.

[0051] See first Figures 8 to 12 The first connector 1 mainly includes an insulating base 11, the first conductive terminals 12 fixed on the insulating base 11, a metal locking plate 13 embedded in the insulating base 11, a first shielding metal frame 14 installed on the insulating base 11, a waterproof sealing ring 15 sleeved on the insulating base 11, and a waterproof ring 16 fixed on the lower surface of the insulating base 11.

[0052] Main references Fig. 9 The insulating base 11 generally comprises a base 111, a convex portion 112 protruding upward from the upper surface of the base 111, and a protruding portion 113 further protruding upward from the convex portion 112. The insulating base 11 is preferably formed by integral injection molding of an insulating material.

[0053] The base 111 is rectangular, and a mounting hole 1111 is provided at each of its four corners. The convex portion 112 is rectangular, and its length is shorter than the length of the base 111, and its width is slightly shorter than the width of the base 111. The outer peripheral surface of the convex portion 112 is provided with a surrounding receiving groove 1121 for receiving the waterproof sealing ring 15. The protruding portion 113 is rectangular, and its width is shorter than the width of the convex portion 112, and its length is the same as the length of the convex portion 112, that is, the two side surfaces of the protruding portion 113 corresponding to the short sides of its rectangle are flush with the side surfaces of the convex portion 112. The flush side surface is defined as a docking side surface 1131, and a guide groove 1133 extending up and down is concavely provided on the docking side surface 1131.

[0054] Still reading Fig. 9 The insulating base 11 is provided with a first docking cavity 115 on the upper surface of the protruding portion 113, wherein, in the preferred embodiment, the first docking cavity 115 is divided into a plurality of compartments, specifically, it has a first signal compartment 1151, a first brake compartment 1152, three first power compartments 1153 and a grounding compartment 1154.

[0055] See also Fig.10 The lower surface of the insulating base 11 is also provided with a second docking cavity 117. Similarly, the second docking cavity 117 is also divided into a plurality of compartments, namely a second signal compartment 1171, a second brake compartment 1172 and three second power compartments 1173. The compartments 1171, 1172, 1173 of the second docking cavity 117 are respectively opposite to the corresponding compartments 1151, 1152, 1153 of the first docking cavity 115 in the vertical direction, and are separated from each other by a partition wall 119 formed inside the insulating base 11.

[0056] Combination Figures 8 to 10 The first conductive terminals 12 are fixed in the insulating base 11 extending in the vertical direction. The first conductive terminals 12 are arranged on the partition wall 119, and their upper ends extend upward into the first docking cavity 115, and their lower ends extend downward into the second docking cavity 117.

[0057] Preferably, the first conductive terminal 12 is a solid needle-shaped conductive element, that is, each cross section thereof is a solid closed shape in its extension direction. The solid needle-shaped first conductive terminal 12 has better strength than the spring-type terminal, and is not prone to the risk of being plugged in and out after repeated insertion, which can improve the contact reliability between the first conductive terminal 12 and the second conductive terminal 22 and the third conductive terminal 32. Moreover, the solid needle shape can also transmit a larger current in the same volume, thereby improving the transmission effect. In addition, the first conductive terminal 12 is preferably integrated with the insulating base 11 through plug-in molding, which can ensure the accuracy of the position, reduce the influence of the position tolerance on the terminal docking, and improve the contact reliability.

[0058] According to the different functions of each first conductive terminal 12, the first conductive terminals 12 are divided into six first signal terminals 121 for transmitting signals, two first brake terminals 122 for realizing the brake function, and three first power terminals 123 for transmitting power. The six first signal terminals 121 are all extended into the first signal compartment 1151 and the second signal compartment 1171, the first brake terminal 122 is correspondingly extended into the first brake compartment 1152 and the second brake compartment 1172, and the first power terminal 123 is correspondingly extended into the first power compartment 1153 and the second power compartment 1173.

[0059] See also Figure 8 and Fig. 9 The main body of the first shielding metal frame 14 is fixed to the first signal compartment 1151 of the first docking cavity 115, and the lower end thereof passes through the partition wall 119 and extends into the second signal compartment 1171 of the second docking cavity 117, surrounding the first signal terminals 121. The first shielding metal frame 14 is arranged around the first signal terminals 121 to play a shielding role and reduce interference in the signal transmission process.

[0060] Main references Fig. 9 The first shielding metal frame 14 is surrounded to form a rectangular frame that is through from top to bottom, and can be formed by a metal sheet. The first shielding metal frame 14 mainly includes four enclosed side walls 141, wherein the upper ends of the two opposite side walls 141 are first bent outward and then downward to form two hanging parts 142. The hanging part 142 can be correspondingly hung at the upper end opening of the first signal compartment 1151, wherein the protruding part 113 is also provided with a corresponding hanging groove 1135 at the upper end opening of the first signal compartment 1151 to accommodate the hanging part 142. A protruding piece 143 protrudes downward from the lower part of each side wall 141 of the first shielding metal frame 14, and a notch 144 is formed between every two protruding pieces 143. The four protruding pieces 143 pass downward through the partition wall 119 and extend into the second signal compartment 1171.

[0061] Part of the side wall 141 and part of the protruding piece 143 of the first shielding metal frame 14 are also provided with a plurality of first elastic abutting parts 145 protruding outwards. These first elastic abutting parts 145 can be formed by stamping the side wall 141 or the protruding piece 143 of the first shielding metal frame 14, and can be an elastic structure with free ends, or an elastic structure with both ends constrained and the middle protruding. These first elastic abutting parts 145 elastically abut against the inner wall of the first docking cavity 115 or the second docking cavity 117, so that they can be tightly combined with the insulating base 11.

[0062] Continue reading Figure 8 and Fig. 9 The metal locking plate 13 can be formed by stamping and bending a metal plate, and is preferably fixed to the insulating base 11 as an integral structure through an insert molding process.

[0063] The metal locking plate 13 includes a substantially rectangular plate-shaped body 131, two locking mechanisms 132 protruding upward from both sides of the plate-shaped body 131, and a first grounding terminal 133 and two grounding plates 134 protruding upward from the middle of the plate-shaped body 131. The middle of the plate-shaped body 131 has an opening 1312 extending vertically through it, and four corners thereof are respectively provided with a mounting hole 1311.

[0064] The plate-shaped body 131 is generally buried in the base 111 of the insulating base 11, and the four corners of the plate-shaped body 131 are exposed on the upper surface of the base 111. The mounting holes 1311 of the plate-shaped body 131 correspond to and communicate with the mounting holes 1111 of the base 111, and are used for the screws 17 to penetrate and fix. The openings 1312 of the plate-shaped body 131 surround the circumference of the first conductive terminals 12 integrated with the insulating base 11, that is, each of the first conductive terminals 12 will penetrate the openings 1312 from top to bottom.

[0065] The two locking mechanisms 132 are arranged on both sides of the opening 1312. When the metal locking plate 13 is fixed to the insulating base 11 as a whole, the locking mechanism 132 protrudes upward from the base 111, and the two locking mechanisms 132 are arranged on both sides of the convex portion 112 of the insulating base 11, and are spaced and opposite to the two docking side surfaces 1131 of the insulating base 11. In this preferred embodiment, the locking mechanism 132 includes a locking piece 1321 bent and extended upward from the side of the plate-shaped body 131, and a locking protrusion 1322 protruding horizontally outward from the surface of the locking piece 1321. The locking piece 1321 is substantially parallel to and opposite to the docking side surface 1131, and the locking protrusion 1322 protrudes in a direction away from the docking side surface 1131. The locking protrusion 1322 can be formed by stamping on the locking piece 1321. The locking protrusion 1322 is generally in the shape of a hollow cylinder, and a locking plane 1324 is formed on its top side. That is, the outer contour of the locking protrusion 1322 is not a complete circle, but the upper part is a straight line, and the lower part is an arc with a central angle greater than 180 degrees connected to the straight line. The locking protrusion 1322 is used to cooperate with the locking arm 252 of the second connector 2 for locking. The structure of the upper flat and lower round can play a role in the convenient and smooth locking process and stable and reliable locking. It is worth mentioning that in some embodiments not shown, the locking protrusion can also be horizontally protruded inward from the surface of the locking piece 1321.

[0066] The first grounding terminal 133 and the two grounding plates 134 are both bent and extended upward from the edge of the opening 1312 of the plate-shaped body 131. The first grounding terminal 133 extends upward into the grounding compartment 1154 of the first docking cavity 115, and the two grounding plates 134 extend upward into the first signal compartment 1151 of the first docking cavity 115.

[0067] according to Figure 8 and Fig. 9 The waterproof sealing ring 15 is sleeved in the receiving groove 1121 of the convex portion 112 of the insulating base 11 to provide waterproof sealing when the first connector 1 and the second connector 2 are plugged in.

[0068] according to Figure 7 and Fig.11 The waterproof ring 16 is fixed to the lower surface of the base 111 of the insulating base 11. When the first connector 1 is installed on the motor 500, the waterproof ring 16 is located between the contact surface of the insulating base 11 and the motor 500 to play a waterproof role.

[0069] The assembly process of the first connector 1 is roughly as follows: the insulating base 11, the first conductive terminals 12 and the metal locking plate 13 are formed into an integrated structure through plug-in, the waterproof ring 16 and the waterproof sealing ring 15 are respectively sleeved on the insulating base 11, and finally the first shielding metal frame 14 is plugged into the insulating base 11.

[0070] See also Fig.10 and Fig.11 The first terminal module 3 includes a housing 31 and a plurality of third conductive terminals 32 fixed in the housing 31. The first terminal module 3 is used to connect the encoder (not shown in the figure) of the motor 500 through a connecting wire (not shown in the figure). The second terminal module 3a also includes a housing 31 and a plurality of third conductive terminals 32, and the lower end of each third conductive terminal 32 is respectively connected to a connecting wire 33. The second terminal module 3a is used to connect the power port and the brake port of the motor 500.

[0071] The housings 31 of the first terminal module 3 and the second terminal module 3a can be respectively inserted into the second docking cavity 117 of the first connector 1. Specifically, in this preferred embodiment, the housing 31 of the first terminal module 3 is inserted into the second signal compartment 1171 of the second docking cavity 117, and the housing 31 of the second terminal module 3a is inserted into the second brake compartment 1172 and the second power compartment 1173 of the second docking cavity 117. Accordingly, each third conductive terminal 32 of the first terminal module 3 can be respectively connected to the lower end of the first signal terminal 121 in the first connector 1. Each third conductive terminal 32 of the second terminal module 3a is respectively connected to the lower end of the first brake terminal 122 and the first power terminal 123 in the first connector 1.

[0072] Among them, see Fig.11 The third conductive terminal 32 has an elastic docking portion 321 located at the top and a wiring portion 323 located at the bottom. When docking with the solid needle-shaped first conductive terminal 12, the elastic docking portion 321 of the third conductive terminal 32 can elastically clamp the lower end of the first conductive terminal 12. At the same time, the contact surface of the two docking has a large length along the up and down direction, which can absorb the position tolerance and ensure the reliability of docking.

[0073] Next Read Figure 12 to Figure 14 The second connector 2 mainly includes a terminal base 21, a plurality of second conductive terminals 22 fixed on the terminal base 21, a cable 23 electrically connected to the second conductive terminals 22, an outer cover 24 covering the terminal base 21, a locking element 25 pivotally connected to the outer cover 24, and a second shielding metal frame 26 mounted on the terminal base 21.

[0074] The terminal base 21 is provided with a plurality of terminal cavities 211 extending up and down, and two mating parts 212 protruding upward are provided on both sides of the terminal base 21, and a wiring space is formed between the two mating parts 212. A recess 2121 is recessed in the middle of the outer side surface of each mating part 212, and two recessed slots 2123 separated from each other are further recessed in the bottom surface of the recess 2121.

[0075] According to the different functions of the second conductive terminals 22, the second conductive terminals 22 are divided into six second signal terminals 221 for transmitting signals, two second brake terminals 222 for realizing the brake function, three second power terminals 223 for transmitting power, and a second ground terminal 224 (wherein the second ground terminal 224 is as shown in FIG. Fig.13 shown).

[0076] See also Fig.15 Each second conductive terminal 22 has a connection portion 2201 at the upper end and an elastic docking portion 2202 at the lower end. Preferably, the second conductive terminal 22 is a metal terminal, and the elastic docking portion 2202 has two elastic contact arms 2204 extending toward each other.

[0077] Combination Fig.17 These second conductive terminals 22 are respectively inserted into the terminal cavity 211 of the terminal seat 21, and the elastic docking portion 2202 of each second conductive terminal 22 faces downward, and is respectively used to connect with the upper end of each corresponding first conductive terminal 12, wherein the two elastic contact arms 2204 of the elastic docking portion 2202 elastically clamp the upper end of the first conductive terminal 12.

[0078] Combination Fig.17 and Fig.14 The second shielding metal frame 26 is disposed around the second signal terminals 221 to provide shielding to reduce interference during signal transmission. The second shielding metal frame 26 is fixedly mounted on the terminal base 21 .

[0079] The second shielding metal frame 26 is preferably formed by enclosing metal sheets, with a closed top and a through hole 261 for the cable 23 to pass through one side. A plurality of second elastic abutting tops 262 are respectively protruded outwardly on two opposite side walls of the second shielding metal frame 26. These second elastic abutting tops 262 elastically abut against the inner wall of the terminal cavity 211 of the terminal seat 21, so as to be tightly combined with the terminal seat 21.

[0080] See also Fig.13The cable 23 includes a plurality of wires 231 and a sheath 232 covering the plurality of wires 231. The ends of the plurality of wires 231 extend forward from the sheath 232 and can extend into the wiring space of the terminal block 21 to respectively connect to the second conductive terminals 22.

[0081] Combination Fig.13 and Fig.14 The outer cover 24 includes a cover body 241 and a wire-passing portion 242 extending backward from the rear side of the cover body 241. The outer cover 24 is preferably made of plastic integrally injection molded. The cover body 241 is roughly a rectangular structure with an opening at the lower end and a hollow interior, so as to be correspondingly covered on the terminal seat 21. The wire-passing portion 242 is roughly cylindrical and communicates with the interior of the cover body 241. The second connector 2 also includes a silicone ring 27, a locking member 28 and a sealing cap 29, which are sleeved on the cable 23 and connected to the wire-passing portion 242 to fix the cable 23 on the wire-passing portion 242 and achieve sealing.

[0082] The inner surface of the cover 241 protrudes downwards from the two side walls thereof, and a guide rib 2411 and two elastic buckle arms 2412 are arranged on both sides of the guide rib 2411. The guide rib 2411 extends downwards beyond the elastic buckle arms 2412. Fig.17 The guide rib 2411 and the two elastic buckle arms 2412 can extend into the clearance groove 2121 of the terminal seat 21 correspondingly, wherein the elastic buckle arm 2412 is correspondingly clamped with the clamping groove 2123 of the terminal seat 21, thereby fixing the terminal seat 21 and the cover body 241 together.

[0083] Two pivot grooves 2413 are provided on both sides of the cover 241, and a retaining wall 2414 is provided on the outer side of each of the two side walls of the cover 241. The pivot groove 2413 is located between the retaining wall 2414 and the side wall. A rotating shaft groove 2415 is further recessed above the pivot groove 2413, and the axes of the rotating shaft grooves 2415 on both sides of the cover 241 are on the same straight line.

[0084] The front outer surface of the cover body 241 is a sloped surface that slopes downward, and two locking protrusions 2416 are protruding forward. The upper surface of the locking protrusion 2416 is a sloped surface that slopes gradually downward in the forward direction, and the lower surface is substantially perpendicular to the front outer surface of the cover body 241. In this preferred embodiment, each locking protrusion 2416 is provided with an unlocking groove 2417 that extends obliquely in the up-down direction, and the unlocking groove 2417 divides the locking protrusion 2416 into two parts.

[0085] Still reading Fig.13 and Fig.14The locking element 25 includes a body 251, two locking arms 252 extending from two sides of the body 251, a handle 253 extending outward from the upper end of the body 251, and two locking springs 254 extending from the body 251 toward the cover 241. Specifically in this embodiment, the body 251 of the locking element 25 is provided with two openings 255, and the lower edge of each opening 255 is bent upward and inward to extend the locking spring 254. The locking element 25 is preferably made of metal and can be formed by bending a metal sheet.

[0086] The upper portion of the locking arm 252 has a pivoting portion 2521 protruding toward the other locking arm 252. The pivoting portion 2521 is in a hollow cylindrical shape and can be stamped from the locking arm 252. The pivoting portion 2521 can be inserted into the corresponding shaft groove 2415 on the cover 241, so that the locking arm 252 can be pivotally received in the corresponding pivot groove 2413. The lower portion of the locking arm 252 is provided with a fixing notch 2522 on a side away from the body 251. The fixing notch 2522 can be used to be fixed with the locking protrusion 1322 of the first connector 1.

[0087] The handle 253 can be held by an operator to enable the body 251 to move above the cover 241 and drive the locking arm 252 to rotate.

[0088] The position of the locking spring piece 254 corresponds to the locking protrusion 2416 on the outer cover 24 , and the locking spring piece 254 can be stopped by the locking protrusion 2416 , thereby preventing the locking element 25 from pivoting.

[0089] The assembly process of the second connector 2 is roughly as follows: first, the second conductive terminals 22 and the second shielding metal frame 26 are respectively installed in the terminal seat 21, and then the front end of the cable 23 is passed through the wire-passing portion 242 of the outer cover 24, and each wire 231 of the cable 23 is respectively connected to the wiring portion 2201 of each second conductive terminal 22, and then the terminal seat 21 is installed in the cover body 241 of the outer cover 24, so that the elastic buckle arm 2412 in the cover body 241 is fastened with the card slot 2123 of the terminal seat 21, and after arranging the cable 23, the sealing cap 29 and the wire-passing portion 242 are rotated and fixed, and the silicone ring 27 and the locking member 28 are squeezed to form a sealing effect between the cable 23 and the wire-passing portion 242, and finally the locking element 25 is installed on the cover body 241 of the outer cover 24.

[0090] Based on the above description, see Fig.12 , Figures 16 to 19 Before the first connector 1 and the second connector 2 are mated, the locking element 25 of the second connector 2 is kept in the Fig.12The free state shown in the figure is then brought into contact with the second connector 2 and the first connector 1 up and down, and the convex portion 112 of the first connector 1 extends into the outer cover 24 of the second connector 2, so that the elastic contact portion 2202 of the second conductive terminal 22 is correspondingly contacted with the upper end of the first conductive terminal 12, thereby establishing an electrical connection between the first connector 1 and the second connector 2. During the contact, the guide rib 2411 of the second connector 2 can be correspondingly inserted into the guide groove 1133 of the first connector 1, guiding the first connector 1 and the second connector 2 to contact smoothly, and facilitating accurate alignment of the two.

[0091] At the same time, the locking mechanism 132 of the first connector 1 extends into the pivoting slot 2413 of the outer cover 24 of the second connector 2 . At this time, locking can be achieved by operating the locking element 25 of the second connector 2 .

[0092] Specifically, the locking element 25 is located at Fig.12 The position shown is the initial state, and the handle 253 of the locking element 25 is pushed downward to rotate the locking element 25 downward until it reaches Fig.18 Lock status shown.

[0093] Specific reference Fig.18 At this time, the locking notch 2522 of the locking arm 252 of the locking element 25 is locked with the locking protrusion 1322 of the locking mechanism 132, locking the first connector 1 and the second connector 2. In particular, since the lower contour of the locking protrusion 1322 is circular, when the locking element 25 rotates downward, the locking notch 2522 of the locking arm 252 cooperates with the locking protrusion 1322, so that the locking arm 252 can move smoothly. After reaching the locked state, the locking notch 2522 fits with the locking plane 1324 on the top side of the locking protrusion 1322, and the locking plane 1324 will prevent the locking arm 252 from further rotating, making the locking more secure.

[0094] Combination Fig.17 In the locked state, the retaining wall 2414 of the outer cover 24 also blocks the outer side of the locking notch 2522 of the locking arm 252, which can prevent improper contact from the outer side and prevent the locking arm 252 from improper pivoting, thereby further improving the reliability of locking.

[0095] In addition, see Fig.19 In the locked state, the locking protrusion 2416 stops above the locking spring 254, thereby preventing the locking element 25 from rotating upward to unlock, so that the locking element 25 remains in the locked state.

[0096] When the locking state between the first connector 1 and the second connector 2 needs to be released, since the unlocking groove 2417 is connected to the inner side of the locking spring 254, the operator can use a needle-shaped tool to pass through the unlocking groove 2417 on the locking protrusion 2416, extend into the inner side of the locking spring 254, and push the locking spring 254 upward, thereby releasing the blocking of the locking protrusion 2416 on the locking spring 254, and then push the locking element 25 to rotate upward, release the locking arm 252 of the locking element 25 and the locking protrusion 1322 of the locking mechanism 132, and the first connector 1 and the second connector 2 can be easily separated. Since the locking spring 254 is integrally formed on the locking element 25 made of metal, it has a high structural strength and can maintain good reliability even after multiple locking and unlocking operations.

[0097] Based on the above description, the connector assembly 100 of the preferred embodiment has the following beneficial effects: in the first connector 1, two locking mechanisms 132 are protruded from a metal locking plate 13 embedded in the insulating base 11, and are correspondingly combined and locked together with the locking element 25 in the second connector 2. The structural strength of the locking mechanism 132 is good, making the locking firm and reliable. In the second connector 2, the locking spring 254 can be stopped by the locking protrusion 2416, so that the locking element 25 remains in a locked state, and can be easily locked and unlocked.

[0098] The first connector 1 uses a solid needle-shaped first conductive terminal 12, and the second conductive terminal 22 and the third conductive terminal 32 use elastic docking parts to respectively connect with the upper end or the lower end of the first conductive terminal 12. This docking structure can reduce the influence of position tolerance when using multiple terminal modules, and facilitate smooth docking. The needle-shaped first conductive terminal 12 can also increase strength and is not easy to collapse. Moreover, when the connector assembly 100 is in a docking state, the first conductive terminal 12 can achieve reliable docking with the second conductive terminal 22 and the third conductive terminal 32, thereby improving the quality of current transmission. In addition, a larger current can be transmitted in the same volume, thereby improving transmission efficiency.

[0099] Fig. 20 The structure of a connector assembly 600 according to another preferred embodiment of the present invention is shown. The connector assembly 600 mainly includes a first connector 6 and a second connector 7 mating with the first connector 6 .

[0100] The main structure of the first connector 6 can refer to the first connector 1 of the previous embodiment, wherein: Fig.21The insulating base 61 and the metal locking plate 63 of the first connector 6 are mainly shown. Compared with the first connector 1, the main difference of the first connector 6 of this embodiment is that the structure of the metal locking plate 63 has some differences.

[0101] Specifically, combined Fig.21 and Fig. 22 The locking mechanism 632 of the metal locking plate 63 includes a locking piece 6321 extending upward and a locking protrusion 6322 protruding outwardly from the locking piece 6321 in a torn manner. The locking piece 6321 is provided with a tearing hole 63211 in the shape of a long strip. The two ends of the locking protrusion 6322 are connected to the front and rear sides of the tearing hole 63211 and are separated from the upper and lower sides of the tearing hole 63211. The locking protrusion 6322 includes a locking section 63221 and two connecting sections 63222 respectively connecting the front and rear ends of the locking section 63221. The two connecting sections 63222 are respectively connected to the front and rear sides of the tearing hole 63211. The locking section 63221 outwardly exceeds the plane where the locking piece 6321 is located. During manufacture, the locking protrusion 6322 is formed by punching outward the sheet material at the tear 63211, wherein the upper and lower sides of the sheet material are torn and protrude outward, while the front and rear ends remain connected to the tear 63211. It is worth mentioning that in some embodiments not shown, the locking protrusion can also be formed by punching and tearing the sheet material at the tear 63211 inward, which can achieve the same effect as the locking protrusion 6322 torn outward. This locking protrusion 6322 has good strength to obtain a more reliable locking effect, and the processing of this locking protrusion 6322 is relatively convenient, and the requirements for material thickness and material elongation are not high. In addition, the size of the locking mechanism 632 finally formed is more accurate in dimensional accuracy.

[0102] Main references Fig. 22 , the locking piece 6321 is provided with a window 63212 below the front and rear ends of the tear 63211, respectively. Each window 63212 is located below a connecting section 63222 of the locking protrusion 6322, and the bottom surfaces of the two connecting sections 63222 form a avoiding curved surface 63225. In this embodiment, the avoiding curved surface 63225 is composed of an upward convex arc surface connected to the locking section 63221 and a horizontal surface away from the locking section 63221. It can be understood that in some embodiments not shown, the specific shape of the avoiding curved surface 63225 is not limited to this and can be designed according to actual conditions. The bottom surface of the locking section 63221 forms a locking plane 63224 extending in the horizontal direction, and the locking plane 63224 extends downward beyond the avoiding curved surface 63225, so that an avoiding space is formed between the locking section 63221 and the avoiding curved surface 63225.

[0103] The other features of the first connector 6 can refer to the first connector 1 mentioned above, and will not be described again here.

[0104] The main structure of the second connector 7 can refer to the second connector 2 of the previous embodiment, wherein: Fig.21 The diagram mainly illustrates the outer cover 74 and the locking element 75 of the second connector 7. Compared with the second connector 2, the second connector 7 of this embodiment is mainly different in that the structure of the locking element 75 is slightly different.

[0105] Specifically, combined Fig.21 and Fig.23 In the locking element 75, a connecting arm 756 is connected between the upper and lower sides of the end of the fixing notch 7522 of each locking arm 752, and the connecting arm 756 arches outward from the locking arm 752 and exceeds the outer surface of the locking arm 752. The connecting arm 756 arches outward from the locking arm 752 in a torn manner, and the upper and lower ends of the connecting arm 756 are obliquely connected to the locking arm 752. The middle part of the connecting arm 756 is roughly parallel to the locking arm 752 and outwardly exceeds the locking arm 752. The connecting arm 756 can be formed by stamping and tearing. It is worth mentioning that although the connecting arm 756 in this embodiment is torn outward, in some embodiments, the connecting arm can also be torn inward.

[0106] The connecting arm 756 connects the upper and lower ends of the fastening notch 7522, which can greatly improve the structural strength of the fastening notch 7522 and prevent the fastening notch 7522 from being stretched when subjected to force, thereby providing a greater locking force and improving the locking reliability. At the same time, the connecting arm 756 arches outward from the locking arm 752, and the difference between the connecting arm 756 and the locking arm 752 forms an escape space, so that the fastening notch 7522 of the locking element 75 can be correspondingly locked into the locking protrusion 6322 of the metal locking plate 63.

[0107] See also Fig.24 and Fig.25 When the first connector 6 and the second connector 7 are mated, the locking protrusion 6322 of the locking mechanism 632 is locked with the locking notch 7522 of the locking arm 752, thereby maintaining the first connector 6 and the second connector 7 in a locked state. At this time, the locking plane 63224 of the locking protrusion 6322 is in contact with the lower side wall of the locking notch 7522, and the locking plane 63224 prevents the locking arm 752 from further rotating, thereby maintaining the locked state.

[0108] Combination Fig.25 and Fig.26When the locking element 75 is rotated toward the locked state, the connecting arm 756 that arches outward from the locking arm 752 can avoid the locking protrusion 6322, and the connecting arm 756 will pass the outer side of the locking protrusion 6322, so that the locking arm 752 can smoothly rotate until the locking notch 7522 is matched with the locking protrusion 6322. Fig. 27 The avoidance curved surface 63225 of the locking protrusion 6322 also avoids the lower side wall of the locking notch 7522, ensuring that the locking arm 752 will not interfere with the locking protrusion 6322 during the rotation process, resulting in a failure to cooperate.

[0109] by Fig. 27 As a reference, the locking arm 752 mounted on the right side of the metal locking plate 63 rotates clockwise to perform the locking operation. At this time, the avoidance curved surface 63225 on the right side of the locking protrusion 6322 plays a role of avoidance. Since the locking protrusion 6322 in this embodiment is provided with the avoidance curved surface 63225 on both the front and rear connecting sections 63222, when the locking element 75 is horizontally flipped 180 degrees and assembled to the left side of the metal locking plate 63, that is, when the locking arm 752 rotates counterclockwise to perform the locking operation, the avoidance curved surface 63225 on the left side of the locking protrusion 6322 avoids the locking arm 752 that rotates counterclockwise to lock. The structure of the locking protrusion 6322 in this embodiment can form a two-way matching relationship, which can be suitable for the situations where the locking arm 752 rotates clockwise and counterclockwise to lock at the same time, thereby improving the versatility in different application scenarios.

[0110] See also Fig.28 and Fig.29 In another preferred embodiment, the locking mechanism 632a may be provided with only one window 63212a on the locking plate 6321a, and the corresponding locking protrusion 6322a may only form the avoidance curved surface 63225a on the bottom surface corresponding to the position of the window 63212a. This design is only suitable for the situation where the locking arm 752 is locked by rotating counterclockwise.

[0111] The above contents are only preferred embodiments of the present invention and are not intended to limit the implementation scheme of the present invention. A person skilled in the art can easily make corresponding changes or modifications based on the main concept and spirit of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope required by the claims.
