[0031] See also Figure 1-Figure 2 As shown, the utility model discloses an integrated connector 100 containing a temperature sensor, which is used to connect to a circuit board (not shown), and includes: a body 1, a conductive terminal 2, and a temperature sensor 3. The utility model arranges the temperature sensor 3 closer to the heating position, shortens the transmission distance, improves the sensitivity of the temperature sensor 3, and makes the temperature measurement more accurate. The integrated connector 100 containing a temperature sensor includes an onboard positive connector and an onboard negative connector. The onboard positive connector is taken as an example for a specific description.

[0032] like Figure 3-Figure 7As shown, the body 1 is provided with a containing space 11, the conductive terminal 2 is accommodated in the containing space 11 and is limitedly connected to the body 1, a containing cavity 20 is provided in the conductive terminal 2, the temperature sensor 3 is placed in the containing cavity 20 and one end extends out of the body 1. Specifically, the body 1 includes a first body 12 and a second body 13, one end of the first body 12 is inserted in the second body 13 and fixedly connected to the second body 13, preferably, an O-ring 4 is provided between the first body 12 and the second body 13, a groove 121 is provided on the outer peripheral side wall of the first body 12, and the O-ring 4 is accommodated in the groove 121, which mainly plays a waterproof role, and the O-ring 4 also makes the first body 12 and the second body 13 more firmly plugged, of course, the first body 12 and the second body 13 can also be slightly shaken to play a role in releasing stress.

[0033] A threaded structure 131 is provided on the outer peripheral wall of the second body 13 near one end of the first body 12. The body 1 also includes a fastener 5 which is sleeved on the threaded structure 131 and detachably connected to the threaded structure 131. The fastener 5 is used to install the integrated connector 100 containing the temperature sensor. Preferably, a sealing gasket 6 is provided on the second body 13 to fix the integrated connector 100 containing the temperature sensor.

[0034] In this embodiment, the conductive terminal 2 includes a connection end 21 accommodated in the body 1 and a free end 22 partially exposed outside the body 1, the connection end 21 is a tubular structure, and the connection end 21 does not contact the inner wall of the body 1, the free end 22 is a plate-like structure, and the free end 22 is electrically connected to the circuit board after extending out of the body 1; a limiting member 23 is provided on the outer peripheral wall of the conductive terminal 2, and a limiting portion 14 is correspondingly provided in the body 1, and the limiting member 23 cooperates with the limiting portion 14 to limit the conductive terminal 2 from rotating in the body 1. Specifically, the limiting member 23 includes a first limiting member 231 located at the connection end 21 and a second limiting member 232 located at the free end 22, the limiting portion 14 includes a positioning structure 141 and a limiting groove 142 located in the first body 12, and the positioning structure 141 is integrally formed with the body 1. In other embodiments, the positioning structure 141 may not be provided, and a separate positioning member may be provided instead, which is sleeved between the conductive terminal 2 and the body 1. When the conductive terminal 2 is accommodated in the body 1, the positioning structure 141 is clamped on the outer peripheral wall of the conductive terminal 2, and the positioning structure 141 is located on the side of the first limiting member 231 close to the second limiting member 232 to limit the retraction of the conductive terminal 2 and ensure that the conductive terminal 2 is located in the center of the accommodating space 11. The second limiting member 232 is accommodated in the limiting groove 142 to limit the rotation of the conductive terminal 2 in the body 1. In this way, the conductive terminal 2 is prevented from retracting or rotating in the body 1 to cause displacement, which affects the connection effect with the device.

[0035] Furthermore, the receiving cavity 20 is formed between the connecting end 21 and the free end 22, and the receiving cavity 20 is communicated with the connecting end 21. In application, the heating position of the integrated connector 100 containing the temperature sensor is located at the connecting end 21 of the conductive terminal 2, that is, the receiving cavity 20 is arranged between the connecting end 21 and the free end 22, closer to the heating position.

[0036] The temperature sensor 3 includes a sensing element 31 and a wire 32 connected to the sensing element 31. The sensing element 31 is fixed in the receiving cavity 20 by glue filling. The sensing element 31 is used to measure the temperature of the connection end 21. It is only necessary to meet the requirement that the sensing element 31 is in direct or indirect contact with the receiving cavity 20 to achieve the purpose of temperature measurement, and then fix the sensing element 31 in the receiving cavity 20. There is no limitation on this. Since the receiving cavity 20 is close to the heating position of the conductive terminal 2, the sensing element 31 is close to the heating position of the conductive terminal 2.

[0037] The body 1 is provided with a conduit 7 for the wire 32 to pass through. The wire 32 is in electrical contact with the conduit 7 and is electrically connected to the circuit board together, which increases the connection strength between the wire 32 and the circuit board. The conduit 7 and the circuit board can be electrically connected by welding, which is not limited. The body 1 includes a pressing plate 8, and a fixing groove 81 is provided on the top of the pressing plate 8. The conduit 7 passes through the fixing groove 81 and is fixed in the fixing groove 81. The fixing groove 81 is formed by being recessed downward from the top of the pressing plate 8, and the opening of the fixing groove 81 is tightened. The conduit 7 is provided with a stopper 71, and the stopper 71 is clamped at one end of the fixing groove 81 to further firmly fix the conduit 7 in the fixing groove 81.

[0038] Preferably, the sensing element 31 is connected to two wires 32, and two conduits 7 are provided on the corresponding body 1. The wires 32 pass through the conduits 7 respectively, and then two sets of fixing grooves 81 arranged side by side and at intervals are provided on the top of the pressing plate 8. An installation groove 132 is provided at one end of the second body 13 away from the first body 12, and the pressing plate 8 is installed in the installation groove 132, and buckles 82 are provided on both sides of the pressing plate 8, and buckle grooves 1321 are correspondingly provided in the installation groove 132, so that the pressing plate 8 is fixedly connected to the second body 13. That is to say, when assembling the integrated connector 100 containing a temperature sensor, the conduit 7 and the pressing plate 8 are first installed and fixed, and then the wires 32 are respectively passed through the conduits 7, and then the conduit 7 and the pressing plate 8 are installed together on the second body 13.

[0039] The inner cavity of the catheter 7 is provided with a protrusion (not shown), and the protrusion squeezes the wire 32 so that the wire 32 is fixed in the catheter 7. The body 1 is provided with a guide groove 15, and the guide groove 15 is connected with the receiving cavity 20. After the wire 32 passes through the guide groove 15 and the catheter 7 from the receiving cavity 20, it is exposed to the outside of the body 1. The wire 32 can also be cut to expose the wire 32 to an appropriate length. Of course, in other embodiments, the wire 32 can also be received in the catheter 7, and there is no restriction on the location, as long as the wire 32 is electrically in contact with the catheter 7.

[0040] like Figure 8-Figure 10As shown, when the integrated connector 100 containing a temperature sensor is a board-mounted negative connector, the setting of the temperature sensor 3 is the same as the above case, and the main difference lies in that the first body 12 and the conductive terminal 2 are different. A positioning member 9 is provided in the body 1, and the positioning member 9 is clamped and fixed to the body 1. When the conductive terminal 2 is accommodated in the body 1, the positioning member 9 is clamped on the outer peripheral wall of the conductive terminal 2, and the limiting groove 142 is provided on the positioning member 9. In this embodiment, the connecting end 21 of the conductive terminal 2 is in close contact with the inner wall of the body 1.

[0041] In summary, the utility model sets a receiving cavity 20 in the conductive terminal 2, and places the temperature sensor 3 in the receiving cavity 20 with one end extending out of the body 1, so that the sensing element 31 of the temperature sensor 3 can be close to the heating position of the conductive terminal 2. In addition, by setting a conduit 7 on the body 1 for the wire 32 of the temperature sensor 3 to pass through, the wire 32 is electrically in contact with the conduit 7, and is electrically connected to the circuit board together, thereby increasing the connection strength between the wire 32 and the circuit board. Compared with the prior art, the utility model shortens the transmission distance and improves the sensitivity of the temperature sensor 3 by setting the temperature sensor 3 closer to the heating position, so that the temperature measurement is more accurate.

[0042] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
