Description

Technical Field

[0001] The present invention relates to the technical field related to electric devices, in particular to a data acquisition and transmission device installation structure. Background Art

[0002] It is well known that the data acquisition and transmission device can realize the full process and full link supervision of the factory operating data, and through the operating data and operation information, it can realize the full process of the enterprise and the whole environment of the site; realize the supervision of all elements of data, including: flow, turbidity, liquid level, temperature and humidity, pressure, site environmental information, operation information, and comprehensively integrate various types of information.

[0003] The data acquisition and transmission device needs to be connected to the wiring harness for data transmission during use, and the installation mechanism between the wiring harnesses is usually a connector mechanism, which is a device that connects two active devices, and builds a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. The connector includes a male end and a female end that connect the wiring harness, and a terminal is installed on the connector accordingly. The terminal includes a pin and a plug. Generally, a pin is installed in the male end, and a plug is installed in the female end. The pin and the plug are plugged in to achieve circuit connectivity.

[0004] The connection between the wiring terminal and the connector is made by plugging. In order to prevent the wiring terminal from being detached from the connector due to vibration, pulling of the wiring harness, etc., in the prior art, a limiting fin is arranged on each wiring terminal, and a limiting groove corresponding to the limiting fin is opened on the connector. During the connection between the wiring terminal and the connector, the limiting fin is first squeezed to produce elastic deformation. When it reaches the position of the limiting groove, the squeezing effect disappears. Under the action of the rebound force, the limiting fin is plugged into the limiting groove to lock the wiring terminal on the connector.

[0005] The shortcoming of the prior art is that, in actual application, when inspecting the factory area to collect information, the data acquisition and transmission device needs to be moved, and there is a frequent vibration problem in the use environment. Since the limiting fins are elastic, the limiting method of the limiting fins and the limiting grooves is difficult to stabilize or lock the terminal blocks on the connectors. Therefore, there will still be looseness between the terminal blocks and the connectors, resulting in poor circuit contact. Summary of the invention

[0006] The purpose of the present invention is to provide a data acquisition and transmission device installation structure to solve the technical problems in the related art.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A data acquisition and transmission device installation structure includes a connector, the connector includes a male end and a female end plugged with the male end, at least one accommodating cavity is arranged on the male end and the female end, a wiring terminal is installed in the accommodating cavity, a limiting fin is arranged on the wiring terminal, and a limiting groove is provided in the accommodating cavity. When the limiting fin is plugged into the limiting groove, a primary lock is formed between the accommodating cavity and the wiring terminal. The connector also includes an abutment block plugged with the accommodating cavity, and a limiting opening is provided on the abutment block. The male end and the female end are both arranged with a limiting block; when each limiting opening is engaged with the limiting block at the corresponding position, the abutment block squeezes the end of the wiring terminal to limit the movement of the wiring terminal in the direction of entering and exiting the accommodating cavity, and the abutment block forms a secondary lock on the wiring terminal in the accommodating cavity.

[0009] As mentioned above, when the male end and the female end are plugged together, a sealing strip is provided at the gap where the two contact.

[0010] As mentioned above, the abutting ends of the limiting fin and the limiting groove have a first abutting surface and a second abutting surface, the abutting portion of the limiting groove and the limiting fin includes a third abutting surface and a fourth abutting surface, and the abutting block is provided with an abutting rod; when the terminal is inserted into the accommodating cavity, the first abutting surface abuts against the third abutting surface, and under the action of external force, the terminal can be pulled out of the accommodating cavity; when the abutting block abuts against the end of the terminal, the limiting fin undergoes elastic deformation based on the extrusion action of the abutting rod to drive the second abutting surface to abut against the fourth abutting surface, and under the action of external force, the terminal cannot be pulled out of the accommodating cavity.

[0011] As mentioned above, in the plug-in direction of the male end and the female end, an upper clamping part is slidably provided on the male end, and a lower clamping part is slidably provided on the female end; after the male end and the female end are plugged in, the upper clamping part and the lower clamping part are clamped in, forming a restriction on the separation of the male end and the female end in the plug-in direction.

[0012] As mentioned above, a squeezing block is arranged on the female end. When the male end needs to be separated from the female end, the squeezing block is pressed to squeeze the upper clamping part, and the upper clamping part is disengaged from the lower clamping part.

[0013] As mentioned above, the number of the extrusion blocks is two. When the upper clamping portion is extruded, the two extrusion blocks simultaneously perform an extrusion action on both sides of the upper clamping portion in a direction perpendicular to the plug-in direction.

[0014] As mentioned above, the upper clamping portion includes an upper push-pull section and two upper clamping sections arranged on the upper push-pull section, and the lower clamping portion includes a lower push-pull section and two lower clamping sections arranged on the lower push-pull section.

[0015] As mentioned above, the portion of the lower push-pull section between the two lower clamping sections forms a compression on the sealing strip after the male end and the female end are plugged into each other.

[0016] As mentioned above, the upper push-pull section is also arranged with an upper pressing section. When the limiting block on the male end is engaged with the limiting opening on the corresponding abutting block, the upper pressing section presses the portion of the abutting block corresponding to the limiting opening.

[0017] As mentioned above, a pressing section is also arranged on the lower push-pull section. When the limiting block on the female end is engaged with the limiting opening on the corresponding abutting block, the pressing section presses the portion of the abutting block corresponding to the limiting opening.

[0018] The beneficial effect of the present invention is that by setting an abutment block to squeeze the end of the terminal, and utilizing the clamping connection between the limit opening and the limit block to lock the abutment block on the connector, a secondary locking of the terminal on the connector can be formed, so that the terminal can be basically stabilized or locked on the connector, avoiding the problem of looseness causing poor contact.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig.10 The present invention is further described in detail.

[0033] In one embodiment of the present invention, a data acquisition and transmission device installation structure is provided, including a connector 1, the connector 1 including a male end 10 and a female end 11 plugged with the male end 10, at least one accommodating cavity 13 is arranged on the male end 10 and the female end 11, a wiring terminal 2 is installed in the accommodating cavity 13, a limiting fin 20 is arranged on the wiring terminal 2, and a limiting groove 21 is provided in the accommodating cavity 13, when the limiting fin 20 is plugged with the limiting groove 21, a primary locking is formed between the accommodating cavity 13 and the wiring terminal 2, and the connector 1 also includes an abutment block 3 plugged with the accommodating cavity 13, and a limiting opening 30 is provided on the abutment block 3, and the male end 10 and the female end 11 are arranged with a limiting block 31; when each limiting opening 30 is engaged with the limiting block 31 at the corresponding position, the abutment block 3 squeezes the end of the wiring terminal 2 to limit the movement of the wiring terminal 2 in the direction of entering and exiting the accommodating cavity 13, and the abutment block 3 forms a secondary locking of the wiring terminal 2 in the accommodating cavity 13.

[0034] Specifically, the data acquisition and transmission device is a prior art, and its working principle will not be described in detail and is not shown in the schematic diagram. For the convenience of subsequent description and understanding, the plug-in direction of the male end 10 and the female end 11 is assumed to be a first direction, the width direction of the male end 10 is a second direction, and the thickness direction of the male end 10 is a third direction. The first direction, the second direction and the third direction constitute the structure of a spatial rectangular coordinate system, wherein the wiring terminal 2 is used to connect the wire 14, which includes a pin and a plug. The plug can be inserted into the pin, and the two are arranged on the male end 10 and the female end 11 respectively.

[0035] In the actual application of the male end 10 and the female end 11, the number of the wiring terminals 2 arranged on the two will be arranged accordingly according to the needs, that is, at least one accommodating cavity 13 for installing the wiring terminal 2 will be arranged on the male end 10 and the female end 11, wherein the accommodating cavity 13 can be adapted according to the external structure of the installed wiring terminal 2. In the prior art, in order to prevent the wiring terminal 2 from having a tendency to detach from the connector due to vibration, pulling of the wiring harness, etc., at least one limiting fin 20 will be arranged on each wiring terminal 2, and a limiting groove 21 corresponding to the limiting fin 20 is opened in the accommodating cavity 13. During the connection between the wiring terminal 2 and the connector, the limiting fin 20 will first be squeezed to produce elastic deformation. When it reaches the position of the limiting groove 21, the squeezing effect disappears. Under the action of the rebound force, the limiting fin 20 is plugged into the limiting groove 21 to lock the wiring terminal 2 on the connector. That is, the size of the accommodating cavity 13 allows the wiring terminal 2 without the limiting fin 20 to freely enter and exit. When the terminal 2 with the limiting fin 20 enters the accommodating cavity 13, the limiting fin 20 will be squeezed by the inner wall of the accommodating cavity 13 and elastically deformed, and the deformation will be in the direction close to the terminal 2. When the limiting fin 20 reaches the limiting groove 21, the limiting groove 21 is equivalent to a part of the inner wall of the accommodating cavity 13 that is recessed. Therefore, there is no squeezing effect on the limiting fin 20 here. Under the action of the rebound force, the limiting fin 20 will enter the limiting groove 21. However, in actual application, when the factory area is inspected and information is collected, the data acquisition and transmission device needs to be moved, and there is a frequent vibration problem in the use environment. Since the limiting fin 20 is elastic, the limiting method of the limiting fin 20 and the limiting groove 21 is difficult to stabilize or the terminal 2 is locked in the accommodating cavity 13. Therefore, there will still be relative movement between the terminal 2 and the accommodating cavity 13, so that the plug and the pin will become loose, resulting in poor circuit contact.

[0036] Based on the above technical problems, in the present embodiment, an abutment block 3 is detachably inserted and arranged in the accommodating cavity 13. When the abutment block 3 is fully inserted into the accommodating cavity 13, the abutment block 3 can squeeze the end of the terminal block 2, and a limiting opening 30 is correspondingly opened on the abutment block 3, and limiting blocks 31 are also arranged on the male end 10 and the female end 11. When the limiting opening 30 is engaged with the limiting block 31, the abutment block 3 will be locked in the accommodating cavity 13, and the abutment block 3 will lock and limit the position of the terminal block 2 in the accommodating cavity 13, wherein the arrangement position of the limiting block 31 on the male end 10 and the arrangement position on the female end 11 are both on a side wall in the second direction, and in the first direction, a wedge-shaped surface and a limiting surface perpendicular to the side wall of the male end 10 in the second direction are sequentially arranged on the limiting block 31. (The arrangement of the limit block 31 on the female end 11 is the same), then during the engagement process between the limit opening 30 and the limit block 31, the abutment block 3 is first elastically deformed by the squeezing action of the wedge-shaped surface, and moves toward the side wall direction away from the male end 10 in the second direction. When the abutment block 3 passes over the wedge-shaped surface and reaches the limit surface, since the limit surface will not squeeze the abutment block 3 in the second direction, under the action of the rebound force, the abutment block 3 moves toward the side wall direction close to the male end 10 in the second direction, so that the limit opening 30 will be engaged with the limit block 31, and the position of the abutment block 3 in the plug-in direction is locked. The locking of the abutment block 3 on the female end 11 is also the same, and no further elaboration will be made here. When the abutment block 3 needs to be removed, it is only necessary to use a tool to partially lift the upper limit opening 30 of the abutment block 3 and separate it from the limit block 31 to achieve the disassembly of the abutment block 3.

[0037] The beneficial effect of this embodiment is that the abutment block 3 is provided to squeeze the end of the terminal block 2, and the abutment block 3 is locked on the connector by utilizing the clamping connection between the limit opening 30 and the limit block 31, so that a secondary locking of the terminal block 2 on the connector can be formed, so that the terminal block 2 can be basically stabilized or locked on the connector, avoiding the problem of looseness causing poor contact.

[0038] Preferably, when the male end 10 and the female end 11 are plugged together, a sealing strip 12 is provided at the gap where the two are in contact; specifically, in some high-humidity and high-dust usage environments, a sealing strip 12 can be arranged at the joint between the male end 10 and the female end 11, and a sealing gasket (not specifically shown in the figure) is also arranged between the abutment block 3 and the wire 14, so as to seal the space inside the male end 10 and the female end 11 to ensure the safety of the connector and extend its service life.

[0039] Furthermore, the abutting ends of the limiting fin 20 and the limiting groove 21 have a first abutting surface 200 and a second abutting surface 201, the abutting portion of the limiting groove 21 and the limiting fin 20 includes a third abutting surface 210 and a fourth abutting surface 211, and an abutting rod 32 is provided on the abutting block 3; when the connecting terminal 2 is inserted into the accommodating cavity 13, the first abutting surface 200 abuts against the third abutting surface 210, and under the action of external force, the connecting terminal 2 can be pulled out of the accommodating cavity 13; when the abutting block 3 abuts against the end of the connecting terminal 2, the limiting fin 20 undergoes elastic deformation based on the extrusion action of the abutting rod 32 to drive the second abutting surface 201 to abut against the fourth abutting surface 211, and under the action of external force, the connecting terminal 2 cannot be pulled out of the accommodating cavity 13.

[0040] Specifically, in the aforementioned embodiment, the insertion of the limiting fin 20 and the limiting groove 21 realizes a primary locking of the wiring terminal 2 in the accommodating cavity 13, and the insertion of the abutment block 3 and the accommodating cavity 13 forms a secondary locking of the wiring terminal 2 in the accommodating cavity 13. However, during use, when the male end 10 and the female end 11 are damaged and the wiring terminal 2 can continue to be used, it is necessary to remove the wiring terminal 2 from the male end 10 or the female end 11. However, in the prior art, the primary locking of the wiring terminal 2 in the accommodating cavity 13 makes it difficult to remove the wiring terminal 2 from the male end 10 or the female end 11 without damage, and the wiring terminal 2 needs to be replaced, which not only increases the replacement time, but also causes a waste of resources.

[0041] Therefore, based on the above problems, in the present embodiment, the first abutting surface 200 and the second abutting surface 201 are arranged at the end where the limiting fin 20 and the limiting groove 21 abut, and the third abutting surface 210 and the fourth abutting surface 211 are arranged at the part where the limiting groove 21 and the limiting fin 20 abut, wherein the first abutting surface 200 and the third abutting surface 210 are wedge-shaped matching structures, that is, when the connecting terminal 2 completely enters the accommodating cavity 13, based on the rebound force of the limiting fin 20, the first abutting surface 200 and the third abutting surface 210 will abut against each other. If there is no external force, when the connecting terminal 2 is in the accommodating cavity 13, the first abutting surface 200 and the third abutting surface 210 are always abutting against each other. When the external force pulls the wire 14, the wedge-shaped matching effect of the first abutting surface 200 and the third abutting surface 210 causes the third abutting surface 210 to squeeze the first abutting surface 200, and the squeezing action will cause The limiting fin 20 is elastically deformed in the direction close to the terminal 2, so that the terminal 2 can be removed from the accommodating cavity 13 without damage. During the use of the connector, the terminal 2 must be locked in the accommodating cavity 13, and an abutment rod 32 corresponding to the limiting fin 20 is installed on the abutment block 3. During the insertion of the abutment block 3 into the accommodating cavity 13, the end of the abutment rod 32 away from the abutment block 3 will exert an extrusion effect on the limiting fin 20, so that the limiting fin 20 is elastically deformed in the direction away from the terminal 2, so that the second abutment surface 201 and the fourth abutment surface 211 are abutted, and the second abutment surface 201 and the fourth abutment surface 211 are basically parallel to each other when abutting, so that it is difficult for the two to be squeezed and moved against each other. In this way, based on the extrusion effect of the abutment rod 32, the terminal 2 is locked in the accommodating cavity 13 once.

[0042] In another embodiment of the present invention, in the plug-in direction of the male end 10 and the female end 11, an upper clamping portion 4 is slidably provided on the male end 10, and a lower clamping portion 5 is slidably provided on the female end 11; after the male end 10 and the female end 11 are plugged in, the upper clamping portion 4 and the lower clamping portion 5 are clamped in, forming a restriction on the separation of the male end 10 and the female end 11 in the plug-in direction.

[0043] Specifically, when the connector is used, it is necessary to ensure that the two wires 14 are firmly connected, and this is achieved by utilizing the friction between the male end 10 and the female end 11. The friction needs to adapt to the vibration in the use environment to prevent the male end 10 and the female end 11 from being separated. Therefore, the increase in friction also means that the connection and separation between the male end 10 and the female end 11 are more difficult, and when high vibration persists, the connection between the male end 10 and the female end 11 will still be loose.

[0044] Based on the above problems, in this embodiment, an upper clamping portion 4 is provided on the male end 10, and a lower clamping portion 5 is provided on the female end 11. After the male end 10 and the female end 11 are plugged together, the upper clamping portion 4 and the lower clamping portion 5 are clamped together, and the male end 10 and the female end 11 are locked after being plugged together to form a restriction on the separation of the male end 10 and the female end 11, wherein the upper clamping portion 4 and the lower clamping portion 5 have basically the same structure, but are arranged in a symmetrical manner 180 degrees around the center, that is, an upper clamping block 40 with the same structure as the limit block 31 is provided on the upper clamping portion 4, and a lower clamping block 50 with the same structure as the limit block 31 is also provided on the lower clamping portion 5. In the process of clamping the upper clamping portion 4 and the lower clamping portion 5, the wedge surface of the upper clamping block 40 and the wedge surface of the lower clamping block 50 are first connected. The wedge-shaped fit forms mutual extrusion, and the upper clamping block 40 is offset in the direction away from the connector, and the lower clamping block 50 is offset in the direction close to the connector. The portion of the upper clamping part 4 connected to the upper clamping block 40 undergoes elastic deformation, and the portion of the lower clamping part 5 connected to the lower clamping block 50 also undergoes elastic deformation, until the limiting surface of the upper clamping block 40 is flush with the limiting surface of the lower clamping block 50, and then under the action of the rebound force, the two limiting surfaces abut against each other, and in the first direction, the upper clamping part 4 and the lower clamping part 5 form mutual restrictions, so that the male end 10 and the female end 11 are locked after being plugged in, wherein the insertion distance of the upper clamping part 4 on the male end 10 toward the female end 11 and the insertion distance of the lower clamping part 5 on the female end 11 toward the male end 10 are just enough for the two limiting surfaces to abut against each other.

[0045] When it is necessary to separate the upper clamping part 4 from the lower clamping part 5, the upper clamping block 40 can be lifted up and separated from the lower clamping block 50 with the help of a tool. The present embodiment also provides a method, that is, an extrusion block 6 is arranged on the female end 11. When it is necessary to separate the male end 10 from the female end 11, the upper clamping part 4 is squeezed by pressing the extrusion block 6, and the upper clamping part 4 and the lower clamping part 5 are disengaged. Specifically, there is also a wedge-shaped matching mechanism between the extrusion block 6 and the upper clamping part 4. By pressing the extrusion block 6, the extrusion block 6 will exert a force on the upper clamping part 4 to move away from the connector, so that the upper clamping block 40 is separated from the lower clamping block 50, thereby achieving the purpose of unlocking.

[0046] As for the connector with multiple accommodating cavities 13, in order to more stably lock the male end 10 and the female end 11, it is necessary to widen the upper clamping part 4 and the lower clamping part 5 in the second direction. Therefore, for the separation of the upper clamping part 4 and the lower clamping part 5, it is also necessary to squeeze the upper clamping part 4 from both sides in the second direction at the same time. That is, in the optional embodiment, the number of extrusion blocks 6 is two. When squeezing the upper clamping part 4, the two extrusion blocks 6 simultaneously form an extrusion action on both sides of the upper clamping part 4 in a direction perpendicular to the plug-in direction (both sides of the upper clamping part 4 in the second direction).

[0047] Furthermore, the upper clamping portion 4 includes an upper push-pull section 41 and two upper clamping sections 42 arranged on the upper push-pull section 41 , and the lower clamping portion 5 includes a lower push-pull section 51 and two lower clamping sections 52 arranged on the lower push-pull section 51 .

[0048] Specifically, in the aforementioned embodiment, by pressing the squeezing block 6, the squeezing effect can be utilized to drive the upper clamping part 4 and the lower clamping part 5 to separate. Therefore, in order to prevent the problem of accidentally touching the squeezing block 6 during use, which causes the upper clamping part 4 to separate from the lower clamping part 5, in this embodiment, the push-pull section is used to drive the two upper clamping sections 42 to move on the male end 10, and the lower push-pull section 51 is used to drive the two lower clamping sections 52 to move on the female end 11, wherein the upper clamping section 42 has two parts, and the corresponding lower clamping section 52 also has two parts, each squeezing block 6 corresponds to an upper clamping section 42, and the positions of the two squeezing blocks 6 are arranged on both sides of the female end 11 in the second direction. If an accidental collision occurs, it is difficult to accidentally touch two squeezing blocks 6 at one time. Therefore, when it is necessary to separate the upper clamping part 4 and the lower clamping part 5, it is necessary to press the two squeezing blocks 6 at the same time to achieve it.

[0049] Preferably, the portion of the lower push-pull section 51 between the two lower clamping sections 52 forms a compression on the sealing strip 12 after the male end 10 and the female end 11 are plugged together, thereby preventing the sealing strip 12 from moving and affecting the sealing effect.

[0050] Furthermore, an upper pressing section 43 is arranged on the upper push-pull section 41. When the limit block 31 on the male end 10 is engaged with the limit opening 30 on the corresponding abutment block 3, the upper pressing section 43 presses the portion of the abutment block 3 corresponding to the limit opening 30; a lower pressing section 53 is also arranged on the lower push-pull section 51. When the limit block 31 on the female end 11 is engaged with the limit opening 30 on the corresponding abutment block 3, the lower pressing section 53 presses the portion of the abutment block 3 corresponding to the limit opening 30.

[0051] Specifically, for replacing the male end 10 and the female end 11, the power should be turned off first, and then the terminal block 2 should be removed from the connector to prevent electric shock. Therefore, in order to avoid the situation in actual operation where the terminal block 2 is removed first and then the male end 10 and the female end 11 are separated, that is, in this embodiment, an upper pressing section 43 is arranged on the upper push-pull section 41, and a lower pressing section 53 is arranged on the lower push-pull section 51. The upper pressing section 43 can press the part of the abutment block 3 on the male end 10 that is in the limit opening 30, and the lower pressing section 53 can press the part of the abutment block 3 on the female end 11 that is in the limit opening 30. In this way, the upper clamping part 4 and the lower clamping part 5 must be separated first, and the upper clamping part 4 must be removed from the male end 10, and the lower clamping part 5 must be removed from the female end 11 before the abutment block 3 can be removed from the accommodating cavity 13.

[0052] Furthermore, limit strips 7 are arranged on the upper pressing section 43 and the lower pressing section 53, and limit slots 8 are arranged at the positions of the upper limit blocks 31 of the male end 10 and the female end 11. That is, in the process of the upper clamping section 42 and the lower clamping section 52 being clamped together, the limit strip 7 on the upper pressing section 43 is plugged into the limit slot 8 opened on the male end 10, and the upper limit opening 30 of the corresponding abutment block 3 is partially pressed along the first direction, and the limit strip 7 on the lower pressing section 53 is plugged into the limit slot 8 opened on the female end 11, and the upper limit opening 30 of the corresponding abutment block 3 is partially pressed along the first direction, so that the problem of insufficient pressing of the upper pressing section 43 or the lower pressing section 53 can be avoided.

[0053] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the protection of the present invention.
