Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a sensor connector. Background Technology

[0002] Connectors are widely used in continuous glucose meters, testing instruments, electronic instruments, electromechanical equipment, communications, aviation, marine, computers, LEDs, automobiles and engineering machinery, etc., mainly to provide power or connect signals.

[0003] Currently, a Chinese invention patent for a sensor connector (application number: 202311095322.4) discloses: "a base and multiple conductive terminals with the same structure, the conductive terminals including a terminal body, a soldering pin, a fixing pin, and a contact pin, the base having a slot for sensor insertion and several terminal mounting slots distributed centrally symmetrically, the terminal mounting slots including a body positioning slot, a soldering pin positioning slot, a fixing pin positioning slot, and a contact pin positioning slot corresponding to the terminal body, soldering pin, fixing pin, and contact pin respectively, the contact pin positioning slot communicating with the slot." However, in the above structure, the slot divides the rubber seat into two parts and the terminal mounting groove into two parts with the same width on the left and right sides. Therefore, when the width of the terminal mounting groove is larger than the thickness of the terminal, it is easy to shift back and forth, resulting in the terminal becoming loose. When the width of the terminal mounting groove is exactly matched with the thickness of the terminal, it is difficult to guarantee the movement space of the terminal, which can easily lead to the terminal being scratched or stuck. Utility Model Content

[0004] The purpose of this utility model is to provide a sensor connector that addresses the shortcomings of the existing technology by solving the technical problem that the slot in the existing connector divides the terminal mounting groove into two parts with the same width on the left and right sides, which can easily lead to loosening or scratching of the terminals.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sensor connector, including a fixing base and multiple terminals. Each terminal includes a contact portion with a hook shape and contact points, a main body portion connected to the contact portion, and a connecting portion for connecting to a circuit board. The main body portion and the connecting portion are vertically connected. The fixing base is provided with a slot for sensor insertion, a first receiving groove for accommodating the contact portion, a second receiving groove for accommodating the main body portion, and a third receiving groove located below the second receiving groove for accommodating the connecting portion. The first receiving groove, the second receiving groove, and the third receiving groove are sequentially connected. The width of the first receiving groove is greater than the width of the second receiving groove. The first receiving groove passes through the slot and is connected to it, so that the sensor abuts against the contact point after being inserted into the slot.

[0006] Furthermore, the contact portion includes a U-shaped elastic segment and an abutment segment disposed at one end of the elastic segment. The other end of the elastic segment is disposed at the bottom front end of the main body. The contact point is disposed at the end of the abutment segment facing the main body and extends into the slot. The abutment segment is located on the side of the slot facing away from the main body.

[0007] Furthermore, the first receiving groove extends vertically through the fixing seat, and the length of the first receiving groove is greater than the length of the contact portion, so as to provide space for the deformation of the elastic section and the abutment section.

[0008] Furthermore, multiple terminals are staggered so that the contacts are staggered on opposite sides of the slot.

[0009] Furthermore, the elastic section, the main body, and the connecting part together form a U-shaped clamping structure. The left and right sides of the third receiving groove are respectively provided with a first step and a second step. The first step and the second step are both located below the second receiving groove. The first step is embedded in the clamping structure, and the main body plate is placed flat above the first step and the second step.

[0010] Furthermore, the connecting part is placed between the first step and the second step, and symmetrically distributed and protruding clamping points are provided on both sides of the connecting part. The clamping points are upwardly curved arc structures.

[0011] Furthermore, the lower end of the connector extends vertically out of the bottom surface of the fixing base.

[0012] Furthermore, reinforcing grooves are provided on the two symmetrical sides of the third receiving groove. The third receiving groove and the reinforcing groove are connected and intersect to form a cross shape. The reinforcing groove extends upward and passes through the fixing seat so that the reinforcing groove is connected to the second receiving groove.

[0013] Furthermore, the bottom surface of the fixing base is provided with a clearance groove that covers the third receiving groove and the reinforcing groove.

[0014] Compared with the prior art, the beneficial effects of this application are as follows: This utility model sets a slot on the fixed base, and the contact point of the contact part is placed in the slot. When the sensor is inserted into the slot, it abuts against the contact point, thereby realizing the electrical connection between the terminal and the sensor. Then, it is connected to the circuit board through the connecting part, so that the sensor and the circuit board are connected. At the same time, the contact part, the main body part and the connecting part are respectively accommodated in the first accommodating groove, the second accommodating groove and the third accommodating groove, and the width of the first accommodating groove is greater than the width of the second accommodating groove. On the one hand, it can fix the main body part of the terminal, and on the other hand, it can ensure the movement space of the contact part. This avoids the phenomenon of the terminal becoming loose or offset, and also prevents the contact part from being scratched or jammed when moving, thus improving the stability and convenience of the connector.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0020] In order to better understand the above-mentioned objectives, technical solutions and advantages of this application, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings, and to understand in detail how to solve the problems raised in the background art.

[0021] like Figures 1 to 5 As shown, a sensor connector includes a mounting base 1 and multiple terminals 2. Each terminal 2 includes a contact portion 21 with a hook shape and a contact point 212, a main body portion 22 connected to the contact portion 21, and a connecting portion 23 for connecting to a circuit board. The main body portion 22 is perpendicularly connected to the connecting portion 23. The mounting base 1 is provided with a slot 11 for sensor insertion, a first receiving groove 12 for accommodating the contact portion 21, a second receiving groove 13 for accommodating the main body portion 22, and a third receiving groove 14 located below the second receiving groove 13 for accommodating the connecting portion 23. The first receiving groove 12, the second receiving groove 13, and the third receiving groove 14 are sequentially connected. The width of the first receiving groove 12 is greater than the width of the second receiving groove 13. The first receiving groove 12 passes through the slot 11 and is connected to it, so that the sensor abuts against the contact point 212 after being inserted into the slot 11.

[0022] With the above solution, the mounting base 1 is provided with a slot 11, and the contact point 212 of the contact part 21 is placed in the slot 11. When the sensor is inserted into the slot 11, it abuts against the contact point 212, thereby realizing the electrical connection between the terminal 2 and the sensor. Then, it is connected to the circuit board through the connecting part 23, so that the sensor and the circuit board are connected. At the same time, the contact part 21, the main body part 22 and the connecting part 23 are respectively accommodated in the first accommodating groove 12, the second accommodating groove 13 and the third accommodating groove 14, and the width of the first accommodating groove 12 is greater than the width of the second accommodating groove 13. On the one hand, it can fix the main body part 22 of the terminal 2, and on the other hand, it can ensure the movement space of the contact part 21. This avoids the terminal 2 from becoming loose or offset, and also prevents the contact part 21 from being scratched or jammed when it moves, thus improving the stability and convenience of the connector.

[0023] In this embodiment, the fixing base 1 is made of plastic, and the number of terminals 2 is 3, which are made of metal. The terminals 2 are fixed to the fixing base 1 by plugging. The slot 11 is adapted to the pin of the sensor, so that the pin can be freely inserted and removed, which is convenient for use and later maintenance. The second receiving groove 13 is adapted to the main body 22, so that the width of the first receiving groove 12 is greater than the thickness of the contact part 21. The second receiving groove 13 penetrates the fixing base 1 to one side to form an opening. The main body 22 is just embedded in the second receiving groove 13. Compared with the prior art where the welding feet protrude from the side of the plastic base, the volume of the connector in the left and right direction can be reduced. It is worth noting that the terminal 2 adopts a flat blanking structure, so that the width of the terminal 2 is consistent, which can also reduce the volume of the connector in the front and back direction, making the connector thinner.

[0024] like Figure 3 and Figure 5 As shown, in one specific embodiment of the improvement, the contact portion 21 includes a U-shaped elastic segment 213 and an abutment segment 211 disposed at one end of the elastic segment 213. The other end of the elastic segment 213 is disposed at the bottom of the front end of the main body portion 22. The contact point 212 is disposed at the end of the abutment segment 211 facing the main body portion 22 and extends into the slot 11. The abutment segment 211 is located on the side of the slot 11 facing away from the main body portion 22.

[0025] Specifically, based on the hook shape of the contact portion 21, the elastic segment 213 and the abutment segment 211 are connected to form a fishhook-shaped structure. The abutment segment 211 and the main body 22 are respectively placed on the left and right sides of the slot 11. The abutment segment 211 is an arc-shaped structure with the protruding end facing the main body 22, so that the contact point 212 extends into the slot 11. When the sensor's pin is inserted into the slot 11, it can contact the contact point 212 on the abutment segment 211. The pin is also inserted from the upper opening of the U-shaped elastic segment 213, and the setting depth of the elastic segment 213 is greater than the setting depth of the slot 11 to avoid the terminal 2 interfering with the pin insertion and to ensure the stability and reliability of the connection.

[0026] like Figure 1 and Figure 3 As shown, in one specific embodiment of the improvement, the first receiving groove 12 extends vertically through the fixing base 1, and the length of the first receiving groove 12 is greater than the length of the contact portion 21, so as to provide space for the elastic section 213 and the abutment section 211 to deform.

[0027] Specifically, the first receiving groove 12 extends vertically through the fixing seat 1, causing the contact portion 21 placed in the first receiving groove 12 to be suspended. When the abutting section 211 is pressed by the pin, the elastic section 213 also moves accordingly, which can prevent the contact portion 21 from contacting the fixing seat 1 and prevent the contact portion 21 from scratching when it moves. In addition, the length of the first receiving groove 12 is greater than the length of the contact portion 21, which allows the abutting section 211 to expand outward. Combined with the fact that the width of the first receiving groove 12 is greater than the width of the terminal 2, it can provide sufficient room for movement, ensuring that the terminal 2 has good elasticity, so that the pin can be fully inserted into the slot 11, and extending the service life of the terminal 2.

[0028] like Figure 1 and Figure 3 As shown, in one specific embodiment of the improvement, multiple terminals 2 are staggered so that contacts 212 are staggered on opposite sides of the slot 11.

[0029] Specifically, there are 3 terminals 2. Two adjacent terminals 2 are spaced apart and arranged opposite each other, so that multiple terminals 2 can clamp the pin from the left and right to ensure the stability of the sensor connection.

[0030] like Figures 3 to 5As shown, in one specific embodiment of the improvement, the elastic segment 213, the main body 22 and the connecting part 23 together form a U-shaped clamping structure. The left and right sides of the third receiving groove 14 are respectively provided with a first step 15 and a second step 16. The first step 15 and the second step 16 are both placed below the second receiving groove 13. The first step 15 is embedded in the clamping structure, and the main body plate is placed flat above the first step 15 and the second step 16.

[0031] Specifically, the top surfaces of the first step 15 and the second step 16 are set on the same horizontal plane. The U-shaped clamping structure is opposite in direction to the elastic segment 213 of the U-shape. When the terminal 2 is inserted, the main body 22 corresponds to the second receiving groove 13 and the connecting part 23 corresponds to the third receiving groove 14, so that the U-shaped clamping structure is engaged with the first step 15 to prevent the terminal 2 from shifting left and right, and improve the stability and shock resistance of the terminal 2 installation. At the same time, the first step 15 and the second step 16 form a support structure, which can also limit the insertion depth of the terminal 2, thereby facilitating the quick installation of the terminal 2.

[0032] like Figure 3 and Figure 5 As shown, in one specific embodiment of the improvement, the connecting part 23 is placed between the first step 15 and the second step 16. The two sides of the connecting part 23 are provided with symmetrically distributed and protruding clamping points 231, which are upwardly curved arc structures.

[0033] Specifically, the third receiving groove 14 extends downward through the fixing base 1. The third receiving groove 14 and the connecting part 23 are adapted to each other. When the connecting part 23 is inserted into the third receiving groove 14, the locking point 231 can enhance the friction with the first step 15 and the second step 16, thereby improving the reliability of the installation and preventing the terminal 2 from falling off or loosening. At the same time, the locking point 231 extends outward along the side of the connecting part 23 and bends upward to form an arc structure, which can facilitate the smooth insertion of the connecting part 23 and also enhance the resistance when the terminal 2 is pulled out, thereby improving the anti-vibration or shock-resistant ability of the terminal 2 after installation.

[0034] like Figure 3 As shown, in one specific embodiment of the improvement, the lower end of the connecting part 23 extends vertically out of the bottom surface of the fixing base 1.

[0035] Specifically, the length of the connecting part 23 is greater than the depth of the third receiving groove 14, so that after the terminal 2 is installed, the lower end of the connecting part 23 extends from the bottom surface of the fixing base 1. In practical applications, when the fixing base 1 is placed above the circuit board, the lower end of the connecting part 23 forms a solder foot, and the connection with the circuit board is achieved by soldering. The terminal 2 is electrically connected to and fixed to the circuit board. Since the circuit board is placed below the fixing base 1, the sensor pin is inserted above the fixing base 1 to avoid mutual interference between the two and facilitate the insertion and removal of the pin.

[0036] like Figure 1 and Figure 3 As shown, in one specific embodiment of the improvement, the third receiving groove 14 is provided with reinforcing grooves 17 on both symmetrical sides. The third receiving groove 14 and the reinforcing groove 17 are connected and intersect to form a cross shape. The reinforcing groove 17 extends upward and passes through the fixing seat 1 so that the reinforcing groove 17 is connected to the second receiving groove 13.

[0037] Specifically, since the fixing seat 1 is a plastic product, it is formed by in-mold injection molding, and the terminal 2 is inserted into the fixing seat 1. When the fixing seat 1 is being formed, the cross-shaped structure can be used to reinforce the strength of the mold parts, thereby increasing the service life of the mold parts. The reinforcing groove 17, the second receiving groove 13 and the third receiving groove 14 are connected, which can facilitate the automated production of the fixing seat 1.

[0038] like Figure 1 and Figure 3 As shown, in one specific embodiment of the improvement, the bottom surface of the fixing base 1 is provided with a relief groove 18 that covers the third receiving groove 14 and the reinforcing groove 17.

[0039] Specifically, the clearance groove 18 is connected to the third receiving groove 14 and the reinforcing groove 17. The wall of the clearance groove 18 is 0.1-0.15mm lower than the bottom surface of the fixing base 1. The clearance groove 18 and the reinforcing groove 17 are designed to facilitate the solder paste to climb during the soldering of the connection part 23, avoid the phenomenon that the connector is easy to float after soldering, ensure the soldering quality of the terminal 2, and improve the stability of the connection.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
