Description

Technical Field

[0001] This utility model belongs to the field of terminal block technology, specifically relating to a terminal block and a Coriolis mass flow meter. Background Technology

[0002] A Coriolis mass flow meter is a mass flow meter that uses the modulation effect of fluid mass flow on the oscillation of a vibrating tube (i.e., the Coriolis force phenomenon) as its principle, and is used for the purpose of measuring mass flow. It generally consists of a sensor and a transmitter. During use, the mass flow meter needs to be connected to external control circuits and an external power supply. To facilitate later wiring management, the connecting cables should be connected to a terminal block for quick inspection by maintenance personnel.

[0003] In current technologies, when connecting cables to terminals, wire terminals are typically installed at the cable ends. These wire terminals are then fixed to the terminals. However, the lack of a secure connection between the cable and the terminal means that frequent movement of the cable during use can cause loosening between the cable and the wire terminals. This leads to poor contact, affecting the stability of power transmission and ultimately impacting the stable operation of the flow meter.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a terminal block and a Coriolis mass flow meter.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a terminal block and a Coriolis mass flow meter, which can solve the problem of unstable connection between existing terminal blocks and connecting cables.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides a terminal block, including: a base and a cable locking mechanism;

[0008] A connecting box is fixed on the base, a cover plate is installed on the connecting box, a conductive seat is fixed inside the connecting box, a clamping cover plate is installed on the conductive seat, connecting ends are installed on both sides of the conductive seat and the clamping cover plate, and a connecting cable is connected to the other end of the connecting end. Through holes are provided on both sides of the connecting box for the connecting ends to pass through.

[0009] The cable locking mechanism is installed on both sides of the connecting box. The cable locking mechanism includes a pair of connectors. The pair of connectors are respectively fixed on the outer side wall of the through holes on both sides of the connecting box. The connectors are externally threaded with connecting sleeves. A conical head is fixed on the side of the connecting sleeve away from the connecting box. A clamping element is installed inside the conical head. An anti-slip layer is provided inside the clamping element. A shrinkage notch is provided on one side of the clamping element.

[0010] In one or more embodiments of this utility model, two pairs of fixing ear plates are fixed on the base, and a first screw is provided in the fixing ear plate. The base is fixed by fixing the fixing ear plate and the first screw.

[0011] In one or more embodiments of this utility model, the connecting box and the cover plate are both drilled with corresponding first screw holes, and the first screw holes are threaded with second bolts. By tightening the second bolts into the first screw holes, the cover plate is fixed to the connecting box.

[0012] In one or more embodiments of this utility model, corresponding first connecting grooves and second connecting grooves are chiseled on both sides of the conductive base and the clamping cover plate. The connecting end is inserted into the first connecting groove and the second connecting groove, thereby connecting the connecting end and the conductive base.

[0013] In one or more embodiments of this utility model, the conductive base, the clamping cover plate, and the connecting end are all drilled with corresponding second screw holes. A third bolt is threaded into the second screw hole. By tightening the third bolt into the second screw hole, the conductive base, the clamping cover plate, and the connecting end are locked together.

[0014] In one or more embodiments of this utility model, a plurality of clamping bars are fixed on the outer wall of the clamping member. The inclined angle of the clamping bars is consistent with the inclined angle of the conical head. Thus, when the conical head moves toward the connecting box, the conical head locks the clamping member inward through the clamping bars, so that the clamping member clamps the connecting cable.

[0015] In one or more embodiments of this utility model, a limiting block is fixed at one end of the clamping bar near the connector. The limiting block and the clamping member do not contact each other. The limiting block is used to fix one side of the connector and restrict the clamping member from moving towards the connector. Thus, when the connecting sleeve drives the conical head to move towards the connecting box, the conical head tightens the clamping member inward. By preventing the limiting block from contacting the clamping member, the shrinkage and deformation of the clamping member are prevented.

[0016] In one or more embodiments of this utility model, the connector has multiple limiting grooves corresponding to the limiting blocks on the side near the clamping member. The limiting blocks are locked in the limiting grooves, thereby preventing the conical head from rotating the clamping member when the connecting sleeve drives the conical head knob on the connector, thus preventing the clamping member from rotating the connecting cable. At the same time, the size of the limiting groove is slightly larger than the size of the limiting block, so that the limiting block has a reserved movable position when the clamping member retracts.

[0017] In one or more embodiments of this utility model, a tightening ring is fixed to the inner sidewall of the conical head, and the tightening ring is in contact with the outer sidewall of a plurality of clamping bars. The conical head slides on the outer sidewall of the clamping bars through the tightening ring, thereby tightening the clamping member inward and clamping the connecting cable.

[0018] This utility model also discloses a Coriolis mass flow meter, including the terminal block described above.

[0019] Compared with the prior art, this utility model effectively improves the connection stability between the connecting cable and the terminal block through related structural design, thereby effectively improving the stability of power transmission. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1 to 6 As shown, a terminal block in one embodiment of the present invention includes: a base 1 and a cable locking mechanism 2.

[0031] like Figures 1 to 3 As shown, a connecting box 103 is fixed on the base 1, and a cover plate 104 is installed on the connecting box 103. A conductive seat 107 is fixed inside the connecting box 103, and a clamping cover plate 108 is installed on the conductive seat 107. Connecting terminals 114 are installed on both sides of the conductive seat 107 and the clamping cover plate 108. The other end of the connecting terminal 114 is connected to a connecting cable 113. Through holes are provided on both sides of the connecting box 103 for the connecting terminals 114 to pass through.

[0032] Specifically, the connector 114 is installed onto the connector cable 113, and then the connector cable 113 is inserted into the through holes on both sides of the connector box 103. The connector 114 is then connected between the conductive base 107 and the clamping cover plate 108, thereby completing the connection between the two connector cables 113.

[0033] like Figures 4 to 6As shown, the cable locking mechanism 2 is installed on both sides of the connecting box 103, and the cable locking mechanism 2 includes a pair of connectors 201. The pair of connectors 201 are respectively fixed to the outer side walls of the through holes on both sides of the connecting box 103, and the connectors 201 are externally threaded with connecting sleeves 202. A conical head 203 is fixed on the side of the connecting sleeve 202 away from the connecting box 103, and a clamping member 204 is installed inside the conical head 203. An anti-slip layer 209 is provided inside the clamping member 204, and a shrinkage notch 205 is provided on one side of the clamping member 204.

[0034] During installation and use: By tightening the connecting sleeve 202 onto the connector 201 towards the connector box 103, the tapered head 203 tightens the clamping member 204 inward, clamping the clamping member 204 onto the connecting cable 113, thus preventing loosening between the connecting cable 113 and the connecting end 114. The anti-slip layer 209 provides anti-slip properties, and the contraction notch 205 provides a retractable inward position for the clamping member 204.

[0035] like Figures 1 to 3 As shown, two pairs of fixing lugs 101 are fixed on the base 1. First screws 102 are installed inside the fixing lugs 101, and the base 1 is fixed by the fixing lugs 101 and the first screws 102. Corresponding first screw holes 105 are drilled on both the connecting box 103 and the cover plate 104. Second bolts 106 are threaded into the first screw holes 105. By tightening the second bolts 106 into the first screw holes 105, the cover plate 104 is fixed to the connecting box 103.

[0036] like Figures 1 to 3 As shown, both sides of the conductive base 107 and the clamping cover plate 108 are respectively engraved with corresponding first connecting grooves 109 and second connecting grooves 110. The connecting end 114 is inserted into the first connecting groove 109 and the second connecting groove 110. By inserting the connecting end 114 into the first connecting groove 109 and the second connecting groove 110, the connection between the connecting end 114 and the conductive base 107 is achieved. Corresponding second screw holes 111 are engraved on the conductive base 107, the clamping cover plate 108 and the connecting end 114. A third bolt 112 is threaded into the second screw hole 111. By tightening the third bolt 112 into the second screw hole 111, the conductive base 107, the clamping cover plate 108 and the connecting end 114 are locked together.

[0037] like Figures 4 to 6 As shown, multiple clamping bars 206 are fixed on the outer wall of the clamping member 204. The angle of the inclined surface of the clamping bar 206 is consistent with the angle of the inclined surface of the conical head 203. Thus, when the conical head 203 moves toward the connecting box 103, the conical head 203 locks the clamping member 204 inward through the clamping bars 206, so that the clamping member 204 clamps the connecting cable 113.

[0038] like Figures 4 to 6 As shown, a limiting block 207 is fixed at one end of the clamping bar 206 near the connector 201. The limiting block 207 and the clamping member 204 do not contact each other. The limiting block 207 is used to fix one side of the connector 201 and restrict the clamping member 204 from moving towards the connector 201. Thus, when the connecting sleeve 202 drives the conical head 203 to move towards the connecting box 103, the conical head 203 tightens the clamping member 204 inward. Since the limiting block 207 and the clamping member 204 do not contact each other, the limiting block 207 is prevented from affecting the shrinkage and deformation of the clamping member 204.

[0039] like Figures 4 to 6 As shown, the connector 201 has multiple limiting grooves 208 on the side near the clamping member 204 that correspond to the limiting block 207. The limiting block 207 is locked in the limiting groove 208, so that when the connecting sleeve 202 drives the tapered head 203 to rotate on the connector 201, it prevents the tapered head 203 from driving the clamping member 204 to rotate, thereby preventing the clamping member 204 from driving the connecting cable 113 to rotate. At the same time, the size of the limiting groove 208 is slightly larger than the size of the limiting block 207, so that when the clamping member 204 retracts, it provides the limiting block 207 with a movable position.

[0040] like Figures 4 to 6 As shown, a tightening ring 210 is fixed on the inner wall of the conical head 203. The tightening ring 210 is in contact with the outer wall of the multiple clamping bars 206. The conical head 203 slides on the outer wall of the clamping bars 206 through the tightening ring 210, thereby tightening the clamping member 204 inward, so that the clamping member 204 clamps the connecting cable 113.

[0041] An embodiment of this utility model also provides a Coriolis mass flow meter, which includes the above-described terminal block.

[0042] Working principle: When using this terminal block, first open the cover plate 104 from the connection box 103, then unscrew the third bolt 112, and take out a pair of connecting ends 114 from between the conductive base 107 and the clamping cover plate 108. Install the connecting ends 114 at the ends of the connecting cables 113 that need to be connected on both sides. Then, unscrew the connecting sleeve 202 from the connecting head 201, put the connecting sleeve 202 on the connecting cable 113, and then put the clamping part 204 on the connecting cable 113. Then, extend the connecting end 114 from the connecting head 201 into the connection box 103 and lock the connecting end 114 in the first connecting groove 109 and the second connecting groove 110. Then, tighten the third bolt 112 in the second screw hole 111 to fix the connecting end 114 between the conductive base 107 and the clamping cover plate 108. Then, install the cover plate 104 back onto the connection box 103.

[0043] Then, the clamping member 204 is pushed to the side of the connector 201 away from the connecting box 103, so that the limiting block 207 is locked in the limiting groove 208. Then, the connecting sleeve 202 is moved toward the connector 201 and screwed onto the connector 201. During the screwing process, the connecting sleeve 202 drives the conical head 203 to move. The conical head 203 slides on the outer side of the clamping bar 206 through the tightening ring 210. Since the limiting block 207 is pressed against the side of the connector 201, Since the clamping member 204 cannot move, the conical head 203 drives the tightening ring 210 to slide on the outer wall of the clamping bar 206, while tightening the clamping member 204 inward, so that the clamping member 204 is clamped on the connecting cable 113, and the connecting cable 113 is also fixed. In this way, both the connecting cable 113 and the connecting end 114 are fixed, thereby preventing the connecting cable 113 from loosening due to shaking.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
