The first male head and the first female head are inserted into each other, and the second female head and the second male head are inserted into each other. When the first pin enters the inner wall of the first post, it will be clamped by the first crown spring. When the second pin enters the inner wall of the second post, it will be clamped by the second crown spring, thereby facilitating replacement and connection.

[0004] In the above-mentioned scheme, the male head and the female head are inserted into each other and rubbed against each other, and the surface of the male head is in full contact with the crown spring, while the crown spring is in partial contact with the male head. Therefore, the surface of the crown spring will be seriously worn, especially in the case of frequent plugging and unplugging, which will seriously affect the connection stability of the male head and the female head. SUMMARY

[0005] Therefore, it is necessary to provide a direct insertion connector to solve the problem of serious wear and poor connection stability caused by frequent plugging and unplugging.

[0006] The above-mentioned purpose is achieved by the following technical scheme:

[0007] A direct insertion connector comprises:

[0008] A male head assembly comprising a first housing and a plug;

[0009] A female head assembly comprising a second housing and a jack, the jack being located in the second housing, a plurality of elastic crown springs being distributed circumferentially inside the jack, the elastic crown springs having a protruding portion radially inwardly, and the protruding portion being in sliding contact with the plug;

[0010] An adjusting assembly for adjusting the position of the protruding portion of the elastic crown spring, the adjusting assembly being configured to adjust the position of the protruding portion downward by a preset distance at a preset time interval.

[0011] Further, the adjusting assembly comprises two adjusting rings and a supporting ring, the two adjusting rings are coaxially and spaced apart and arranged in the insertion hole in a sliding manner, the two adjusting rings are respectively connected to the upper and lower ends of the plurality of elastic crown spring protrusions in a sliding manner, the supporting ring is fixedly connected to the upper ends of the plurality of elastic crown springs, the supporting ring is connected in the second shell, a push plate is arranged in the second shell in a sliding manner, the push plate is connected to the two adjusting rings, and the push plate is used to push the two adjusting rings to move axially.

[0012] Further, a first threaded ejector rod is arranged on the second shell, the outer periphery of the first threaded ejector rod is threadedly connected to the upper end of the second shell, and the lower end of the first threaded ejector rod abuts against the push plate.

[0013] Further, a plurality of fixing rods are arranged on the outer periphery of the two adjusting rings in a circumferential direction, the upper ends of the plurality of fixing rods are fixedly connected to the outer periphery of the upper adjusting ring, and the lower ends of the plurality of fixing rods are fixedly connected to the outer periphery of the lower adjusting ring.

[0014] Further, a plurality of fixing rods are arranged on the outer periphery of the two adjusting rings in a circumferential direction, the upper ends of the plurality of fixing rods are fixedly connected to the outer periphery of the upper adjusting ring, and the lower ends of the plurality of fixing rods are fixedly connected to the outer periphery of the lower adjusting ring.

[0015] Further, the elastic member is a compression spring.

[0016] Further, a supporting plate is arranged in the second shell in a sliding manner, the supporting plate is connected to the supporting ring, a second threaded ejector rod is arranged on the second shell, the outer periphery of the second threaded ejector rod is threadedly connected to the second shell, and the lower end of the second threaded ejector rod abuts against the supporting plate.

[0017] Further, an elastic telescopic rod is arranged on the lower end face of the supporting ring, one end of the elastic telescopic rod is fixedly connected to the inside of the second shell, the other end of the elastic telescopic rod is fixedly connected to the lower end face of the supporting ring, and the elastic telescopic rod has a tendency to push the supporting ring to move upward.

[0018] Further, a rotating tooth ring is arranged in the first shell in a rotating manner, a dialing block is arranged on the second shell, the dialing block can be matched with the teeth of the rotating tooth ring, and the dialing block is configured to push the rotating tooth ring to rotate by a preset angle when the plug enters the insertion hole.

[0019] Further, the elastic crown spring is an elastic metal sheet.

[0020] The beneficial effects of this invention are:

[0021] This invention incorporates an adjustment component that can adjust the position of the protrusion on the elastic crown spring from top to bottom by a preset distance at preset time intervals. This causes the unworn area to form a protrusion, ensuring that the protrusion of the elastic crown spring and the plug always maintain close contact. This avoids a decrease in connection stability due to localized wear and significantly extends the service life of the elastic crown spring.

[0022] This invention incorporates multiple push rods connected to two adjusting rings. When a plug is inserted into a socket, the first housing pushes against the push rods, causing the two adjusting rings to move. The two adjusting rings then move the protrusions of the elastic crown springs synchronously, thereby reducing the friction distance between the plug and the protrusions, reducing wear on the plug and protrusions from tiny particles, preventing impurities from interfering with the electrical connection, and improving conductivity stability.

[0023] This invention features a sliding support plate within a second housing. The support plate is connected to a support ring, which is fixedly connected to the upper end of an elastic crown spring. When the elasticity of the crown spring decreases, the support plate is pushed downwards, causing the support ring to press against the upper end of the elastic crown spring. This mechanical compression compensates for the decrease in elasticity of the crown spring, restoring its contact force with the plug. The elastic telescopic rod can assist the support plate in resetting after adjustment, ensuring that the crown spring always maintains appropriate elastic tension and preventing connection failure due to loosening.

[0048] The present application provides a direct insertion connector. Figures 1-17 The present application provides a direct insertion connector.

[0049] The invention discloses a straight plug-in connector, which comprises a male head assembly 100 and a female head assembly 200, the male head assembly 100 comprises a first shell 120 and a plug 110, the plug 110 is arranged in the first shell 120, the plug 110 is multiple, the female head assembly 200 comprises a second shell 220 and a jack 210, the jack 210 is arranged in the second shell 220, the jack 210 is also multiple, the number of the jack 210 is same as the number of the plug 110, a plurality of elastic crown springs 300 are distributed in each jack 210, the plurality of elastic crown springs 300 have a convex part 310 which is radially inward to the jack 210, the convex part 310 can be in sliding contact with the plug 110, the elastic crown spring 300 is an elastic metal sheet, the elastic metal sheet is elastic and can conduct electricity, the first shell 120 and the second shell 220 are connected with wires 150, the wire 150 in the first shell 120 is electrically connected with the plug 110, the wire 150 in the second shell 220 is electrically connected with the plurality of elastic crown springs 300 in the jack 210, when the plug 110 is inserted into the jack and the plug 110 is in sliding connection with the elastic crown spring 300, the two are electrically connected.

[0050] The plug 110 in the prior art is in frictional contact with the elastic crown spring 300 when it is inserted into the jack 210 and connected with the elastic crown spring 300, and it is always in frictional contact with the same position, which can cause the elastic crown spring 300 to be seriously worn out when it is frequently inserted and pulled out, thereby affecting the stability of the connection between the plug 110 and the jack 210.

[0051] Therefore, the invention is provided to avoid the plug 110 being in frictional contact with a certain position of the elastic crown spring 300 when it is inserted into the jack 210, an adjusting assembly is arranged on the second shell 220, the adjusting assembly is used for adjusting the position of the convex part 310 on the elastic crown spring 300, so that the position of the convex part 310 is constantly changed, it can be understood that the position of the convex part 310 on the elastic crown spring 300 will be seriously worn out after the jack 210 and the plug 110 are inserted and pulled out for a certain number of times, and the adjusting assembly can move the convex part 310 of the elastic crown spring 300 from the seriously worn-out area to the area which has not been worn out, so that the convex part 310 on the elastic crown spring 300 is tightly connected with the plug 110, thereby improving the stability of the connection between the two.

[0052] It should be noted that the adjusting assembly can adjust the position of the convex part 310 on the elastic crown spring 300 by a preset distance from top to bottom within a preset time interval, the preset time refers to the time required after the plug 110 and the jack 210 are inserted and pulled out for a certain number of times, and the preset distance refers to the distance moved by the convex part 310 each time, which is just enough to avoid the last worn-out area, so that a new area which has not been worn out forms the convex part 310, thereby making the convex part 310 electrically connected with the plug 110.

[0053] Specifically, the adjusting assembly in the embodiment includes two adjusting rings 230 and a supporting ring 240, the two adjusting rings 230 are axially slidably arranged in the insertion hole 210, and the two adjusting rings 230 are axially spaced, as shown in Figure 6 and Figure 8 As shown in the drawings, a plurality of arc-shaped grooves 231 are formed on the two adjusting rings 230, the plurality of arc-shaped grooves 231 allow the elastic crown springs 300 to pass through, the two adjusting rings 230 are respectively sleeved on the upper and lower ends of the plurality of elastic crown springs 300, and the supporting ring 240 is fixedly connected to the upper end of the elastic crown springs 300 for supporting the upper end of the elastic crown springs 300, the lower end of the elastic crown springs 300 is fixedly arranged at the bottom of the second shell 220, when the two adjusting rings 230 move axially, the upper and lower ends of the protrusions 310 are pushed to move, so that the protrusions 310 move on the elastic crown springs 300, and then the position of the protrusions 310 on the elastic crown springs 300 is changed. In order to enable the two adjusting rings 230 to move axially, a push plate 250 is arranged in the second shell 220, the push plate 250 can move in the vertical direction, the push plate 250 is connected to the two adjusting rings 230, when the push plate 250 moves in the vertical direction, the two adjusting rings 230 are synchronously moved to adjust the position of the protrusions 310 on the elastic crown springs 300.

[0054] It should be noted that the second shell 220 in the embodiment is composed of an upper shell 221, a middle shell 222 and a lower shell 224, as shown in Figure 4 the insertion hole 210 is formed on the upper shell 221, a plurality of through holes 223 are formed on the middle shell 222, the plurality of through holes 223 correspond to the plurality of insertion holes 210 respectively, the lower ends of the plurality of elastic crown springs 300 are fixedly connected to the lower shell 224, when the middle shell 222 is connected to the lower shell 224, the plurality of elastic crown springs 300 pass through the through holes 223 on the middle shell 222, when the upper shell 221 is connected to the middle shell 222, the plurality of elastic crown springs 300 correspond to the insertion holes 210 of the upper shell 221, the push plate 250 in the embodiment is slidably arranged between the middle shell 222 and the upper shell 221, a plurality of first corresponding holes 251 are formed on the push plate 250 to connect the adjusting rings 230, as shown in Figure 10 and Figure 11 the first corresponding holes 251 on the push plate 250 are provided with a first ring groove 252, the upper adjusting ring 230 of the two adjusting rings 230 is located in the first ring groove 252, so that the adjusting ring 230 is connected to the push plate 250.

[0055] Specifically, the embodiment is to drive the pushing plate 250 to move, a first threaded jacking rod 260 is threadedly connected to the upper end surface of the upper shell 221 of the second shell 220, the outer periphery of the first threaded jacking rod 260 is threadedly connected with the upper shell 221, and the lower end of the first threaded jacking rod 260 abuts against the pushing plate 250, and the operator needs to rotate the first threaded jacking rod 260 at a preset interval, the lower end of the first threaded jacking rod 260 pushes the pushing plate 250 to move downward, so that the pushing plate 250 drives the adjusting ring 230 to move downward, since the two adjusting rings 230 are connected together and are slidingly connected to the upper and lower ends of the protrusion 310 of the elastic crown spring 300, the two adjusting rings 230 move the protrusion 310 downward by a preset distance, so that the new position is in electrical contact with the plug 110.

[0056] It should be noted that the two adjusting rings 230 in the application are specifically connected together through a plurality of fixing rods 232, as shown in the figure, the plurality of fixing rods 232 are circumferentially distributed on the outer periphery of the two adjusting rings 230, the upper ends of the plurality of fixing rods 232 are fixedly connected with the outer periphery of the upper adjusting ring 230, and the lower ends of the plurality of fixing rods 232 are fixedly connected with the outer periphery of the lower adjusting ring 230, so that the two adjusting rings 230 move axially synchronously. Figure 8

[0057] In a further embodiment, since the plug 110 and the elastic crown spring 300 in the jack 210 are frictionally connected, when there are small particles such as dust between the plug 110 and the protrusion 310 of the elastic crown spring 300, the elastic crown spring 300 may be seriously worn due to friction, and these small particles will wear the plug 110 and the elastic crown spring 300 when the plug 110 and the elastic crown spring 300 slide relative to each other, and these small particles will affect the stability of the electrical connection.

[0058] Therefore, in order to reduce the influence of small particles on the stability of the electrical connection, the plurality of fixing rods 232 in the application are provided with a rack 233 parallel to the axis of the fixing rod 232, and a pushing rod 270 is axially slidingly arranged on the edge of the jack 210, the outer periphery of the pushing rod 270 is provided with a tooth 271, the tooth 271 is engaged with the rack 233 on the fixing rod 232, when the pushing rod 270 moves axially, the plurality of fixing rods 232 are driven to move synchronously through the engagement of the tooth 271 and the rack 233, and the plurality of fixing rods 232 in turn drive the two adjusting rings 230 to move synchronously, so that the two adjusting rings 230 move the protrusion 310 on the elastic crown spring 300 downward by a distance.

[0059] ​The number of the pushing rods 270 in the embodiment is the same as that of the fixing rods 232, and the upper end position of the pushing rods 270 is higher than that of the jack 210, so when the plug 110 is inserted into the jack 210 and reaches the bottom, the pushing rods 270 are pushed, and the pushing rods 270 move downward, the lower end of the pushing rods 270 is provided with an elastic element, one end of the elastic element abuts against the bottom of the second shell 220, specifically, the top end of the middle shell 222 of the second shell 220, and the other end of the elastic element is fixedly connected to the pushing rod 270, the elastic element is a compression spring, and the elastic element makes the pushing rods 270 have a tendency to move upward, so that the pushing rods 270 can reset under the action of the elastic element when not subjected to the force of the plug 110.

[0060] It should be noted that after the operator adjusts the position of the protrusion 310 at the preset time interval, the operator no longer actively adjusts the position of the protrusion 310, the plug 110 is in sliding contact with the protrusion 310 on the elastic crown spring 300 when being inserted into the jack 210, and the plug 110 needs to slide a distance with the protrusion 310 to be inserted in place, so that in the process of sliding, the tiny particles not only aggravate the wear, but also affect the electrical connection stability of the two, and through the pushing rod 270 provided in the application, when the plug 110 is inserted into the jack 210, the first shell 120 connected with the plug 110 pushes the pushing rod 270 after the plug 110 and the elastic crown spring 300 slide a distance, the pushing rod 270 drives the two adjusting rings 230 to move downward through the gear teeth 271 and the gear rack 233, so that the protrusion 310 moves downward synchronously, and in the process of moving downward of the protrusion 310, the plug 110 also moves downward synchronously, so that the relative sliding distance of the plug 110 and the protrusion 310 in the process is very short, thereby reducing the long-time scraping of the tiny particles between the plug 110 and the elastic crown spring 300 to affect the electrical connection stability of the two. Compared with the traditional plug 110 inserted into the elastic crown spring 300 for full-time sliding friction, the plug 110 in the application only has a part of time for sliding friction with the protrusion 310 on the elastic crown spring 300, which can effectively reduce the friction between the plug 110 and the elastic crown spring 300, and improve the electrical connection stability of the plug 110 and the elastic crown spring 300.

[0061] Specifically, in order to facilitate the arrangement of the pushing rod 270, as shown in Figure 10 and Figure 11 , the first sliding groove 253 is arranged on the outer periphery of the first corresponding hole 251 of the pushing plate 250, the extension direction of the first sliding groove 253 is parallel to the axis of the first corresponding hole 251, and the pushing rod 270 is slidingly connected in the first sliding groove 253.

[0062] It can be understood that, as the working time accumulates, the elastic crown spring 300 will relax due to thermal stress after the protrusion 310 on the elastic crown spring 300 is in contact with the plug 110 for a long time, which will cause the contact force between the plug 110 and the protrusion 310 to decrease, and further cause the stability of the connection to be poor.

[0063] Based on this, the support ring 240 is arranged in a structure capable of moving up and down, when the protrusion 310 on the elastic crown spring 300 relaxes, the support ring 240 will drive the upper end of the elastic crown spring 300 to move downward to increase the elasticity of the protrusion 310 on the elastic crown spring 300, thereby avoiding the decrease of the contact force between the plug 110 and the protrusion 310.

[0064] Specifically, the support plate 280 is slidingly arranged in the second shell 220, and the support plate 280 is specifically slidingly arranged in the upper shell 221 of the second shell 220, and the support plate 280 is located above the push plate 250, a plurality of second corresponding holes 281 are formed in the support plate 280, and the second corresponding holes 281 are used to accommodate the support ring 240. Figure 12 and Figure 13 As shown in the drawings, a plurality of second ring grooves 282 are formed in the plurality of second corresponding holes 281, the second ring grooves 282 are used to accommodate the support ring 240, and the support ring 240 is fixedly connected with the upper end of the elastic crown spring 300 and can be synchronously driven to move when the support plate 280 moves in the vertical direction.

[0065] More specifically, in order to drive the support plate 280 to move in the vertical direction, the upper end of the upper shell 221 of the second shell 220 is provided with a second threaded top rod 290, the outer periphery of the second threaded top rod 290 is threadedly connected to the upper end of the upper shell 221, and the lower end of the second threaded top rod 290 abuts against the upper end of the support plate 280, so that the support plate 280 can be pushed to move in the vertical direction when the second threaded top rod 290 is rotated. Meanwhile, in order to enable the support plate 280 to reset, the lower end surface of the support ring 240 is provided with an elastic expansion rod 241, the upper end of the elastic expansion rod 241 is fixed to the lower end surface of the support ring 240, and the lower end of the elastic expansion rod 241 is fixed to the top of the middle shell 222 of the second shell 220, so that the support plate 280 pushes and extrudes the elastic expansion rod 241 to shorten when the support plate 280 is pushed downward by the second threaded top rod 290, and the elastic expansion rod 241 pushes the support ring 240 to move upward to reset when the second threaded top rod 290 is reversely rotated.

[0066] It should be noted that, since the support plate 280 is located above the push plate 250, in order to ensure that the push rod 270 can abut against the first shell 120 on the plug 110, the push plate 250 is provided with a plurality of first corresponding holes 251, and the first corresponding holes 251 are used to accommodate the push rod 270. Figure 12 and Figure 13As shown, the second corresponding hole 281 on the support plate 280 in the embodiment is peripherally provided with a second sliding groove 283, and the pushing rod 270 passes through the first sliding groove 253 of the pushing plate 250 and also passes through the second sliding groove 283 of the support plate 280, so that the upper end of the pushing rod 270 can be higher than the height of the jack 210, and it is ensured that when the plug 110 is inserted into the jack 210, the first shell 120 can abut against the upper end of the pushing rod 270.

[0067] It should be further noted that, in order to avoid the arrangement of the support plate 280 affecting the pushing of the pushing plate 250 by the first threaded ejector rod 260, the support plate 280 in the embodiment is also provided with a through groove 284, the position of the through groove 284 corresponds to the position of the first threaded ejector rod 260, and the first threaded ejector rod 260 in the embodiment has two, so the number of the through grooves 284 is also two, and the first threaded ejector rod 260 passes through the through grooves 284 and abuts against the upper end face of the pushing plate 250. A hole is further arranged between the two through grooves 284, the diameter of the hole is smaller than the diameter of the lower end of the second threaded ejector rod 290, so as not to affect the pushing of the support plate 280 by the second threaded ejector rod 290.

[0068] In a further embodiment, the first shell 120 of the present application is internally provided with a rotating tooth ring 130, as shown in Figure 14 and Figure 15 As shown, the rotating tooth ring 130 has a plurality of one-way tooth tips, and the rotating tooth ring 130 in the embodiment can only rotate in one direction, and a pushing block 140 is arranged on the second shell 220, the pushing block 140 is specifically arranged on the outer sidewall of the upper shell 221 of the second shell 220, and the pushing block 140 is a wedge-shaped block. When the plug 110 is inserted into the jack 210, the pushing block 140 on the second shell 220 will push the rotating tooth ring 130 to rotate by a preset angle, specifically, an angle of one one-way tooth tip. When the plug 110 is pulled out of the jack 210, the pushing block 140 will not drive the rotating tooth ring 130 to rotate in the opposite direction. With the increase of the number of plug insertion and extraction, the rotating angle of the rotating tooth ring 130 is larger.

[0069] It should be noted that, in order to enable the operator to clearly understand the number of plug insertion and extraction and thus determine when to adjust the position of the protrusion 310 on the elastic crown spring 300, the rotating tooth ring 130 in the embodiment is provided with a mark (not shown in the figure). In the factory state, the mark on the rotating tooth ring 130 in the first shell 120 corresponds to the position of the pushing block 140 on the second shell 220. With the increase of the number of plug insertion and extraction, the position of the mark on the rotating tooth ring 130 will change. Since the rotating tooth ring 130 in the embodiment can only rotate in one direction, the number of plug insertion and extraction can be calculated according to the position of the mark.

[0070] For example, a time interval can be set for the rotating gear ring 130 to rotate 360°. After the rotating gear ring 130 rotates 360°, the operator can adjust the position of the protrusion 310 on the elastic crown spring 300 by rotating the first threaded push rod 260.

[0071] The specific working process of the through-hole connector provided by the present invention will be described in conjunction with the above embodiments:

[0072] When the plug 110 is inserted into the socket 210, the first housing 120 connected to the plug 110 will contact the upper end of the push rod 270 when the plug 110 is about to be inserted into the innermost part of the socket 210. As the plug 110 continues to be inserted, the first housing 120 pushes the push rod 270 downward, and the elastic element at the bottom of the push rod 270 is compressed. The push rod 270 drives multiple fixed rods 232 to move downward synchronously through the meshing of the rack 233 and the teeth 271. The multiple fixed rods 232 are fixedly connected to the outer periphery of the two adjusting rings 230, so they will drive the two adjusting rings 230 to move downward synchronously. Since the two adjusting rings 230 are slidably connected to the upper and lower ends of the protrusion 310 of the elastic crown spring 300, the two adjusting rings 230 will drive the protrusion 310 to move downward, thereby reducing the relative friction distance between the plug 110 and the protrusion 310, thus reducing the influence of the small particles between the plug 110 and the protrusion 310 on the stability of the electrical connection.

[0073] Each time the device is plugged in or unplugged, the rotating toothed ring 130 on the first housing 120 is actuated by the actuating block 140 on the second housing 220. After the rotating toothed ring 130 rotates 360°, the protrusion 310 on the elastic crown spring 300 is worn considerably. It is necessary to move the protrusion 310 on the elastic crown spring 300 downward so that the new area becomes the protrusion 310 and thus electrically connects with the plug 110. The operator uses a wrench or other tools to rotate the first threaded push rod 260. The first threaded push rod 260 pushes the push plate 250 downward. The push plate 250 drives the two adjusting rings 230 to move downward synchronously. The two adjusting rings 230 then drive the protrusion 310 on the elastic crown spring 300 to move downward synchronously, thereby changing the position of the protrusion 310 on the elastic crown spring 300 so that the un-rubbed area becomes the protrusion 310 and electrically connects with the plug 110, thus improving the stability of the electrical connection between the plug 110 and the protrusion 310.

[0074] As usage time increases, the protrusion 310 on the elastic crown spring 300 remains under compression for extended periods, causing a decrease in the overall elastic force of the elastic crown spring 300. Therefore, operators need to periodically drive the second threaded push rod 290 to rotate. The lower end of the second threaded push rod 290 pushes the support plate 280 downwards, and the support ring 240 connected to the support plate 280 drives the upper end of the elastic crown spring 300 downwards. Since the lower end of the elastic crown spring 300 is fixedly connected to the bottom inside the second housing 220, the downward movement of the upper end of the elastic crown spring 300 compresses the elastic crown spring 300, allowing its elastic force to be maintained for a longer period. When the elastic force of the elastic crown spring 300 decreases again after a period of use, the second threaded push rod 290 is driven again to increase the service life of the elastic crown spring 300. However, after multiple adjustments, a new elastic crown spring 300 needs to be replaced to avoid safety accidents.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
