Description

Vibration-resistant module connection structure

Technical Field

The utility model relates to the technical field of relay sockets, in particular to a vibration-resistant module connection structure.

Background Art

In order to protect the coil of the relay and eliminate reverse current during use, the relay socket is usually installed with a module with corresponding functions (referred to as the functional module). The functional module is provided with multiple plug-in posts, and each plug-in post is provided with a conductive spring clip. When connected, the plug-in post is inserted into the corresponding socket provided in the socket body of the relay socket. At the same time, the conductive spring clip in the plug-in post clamps the module connection terminal configured in the socket. The above-mentioned plug-in post and the socket are usually fixed by concentric interference fit, but because the socket body and the functional module are both injection molded parts, size control is relatively difficult, and there will be problems with the size being too large or too small, which makes it difficult to install the functional module or it is easy to fall off due to vibration. Although there is a certain clamping force between the conductive spring clip and the module connection terminal, if the module is fixed by this clamping force alone, the stability is not enough and there is still a risk of vibration falling off.

Please refer to Figures 1 to 7, a vibration-resistant module connection structure of the utility model includes a relay socket 10 and a functional module 20 for plugging with the relay socket 10, the functional module 20 is provided with a plurality of hollow plug-in columns 201, and the plug-in columns 201 are provided with conductive clip springs 202. Specifically, the functional module 20 is a plug-in module, which is used to eliminate reverse current and protect the coil of the relay, and the bottom of the functional module 20 is provided with two plug-in columns 201, and each plug-in column 201 extends downward. The relay socket 10 includes a socket body 1, and the socket body 1 is respectively provided with a plug-in hole 11 corresponding to each plug-in column 201 of the functional module 20, and the plug-in hole 11 is suitable for the plug-in column 201 to be inserted, and the module connection terminal 2 is configured in the plug-in hole 11, and specifically, the module connection terminal 2 is in the shape of a long sheet, and a square opening 14 is formed at the bottom of the plug-in hole 11, so that the module connection terminal 2 can be inserted upward from the square opening 14 into the plug-in hole 11. When the plug-in column 201 is inserted into the socket 11, the conductive clamp spring 202 clamps the module connection terminal 2. The inner diameter of at least the outer end of the socket 11 is slightly larger than the outer diameter of the plug-in column 201, so that the plug-in column 201 is easily inserted into the socket 11, and the inner wall surface of the socket 11 is provided with a plurality of first ribs 12 and a plurality of second ribs 13 distributed along its circumference, and the first ribs 12 and the second ribs 13 extend along the depth direction of the socket 11 respectively. After the plug-in column 201 is inserted into the socket 11, the first ribs 12 and the outer side surface of the plug-in column 201 are in interference fit, and the second ribs 13 and the outer side surface of the plug-in column 201 are in non-interference contact fit or small clearance fit.

The inner diameter of the first hole section 111 is larger than the inner diameter of the second hole section 112. The first hole section 111 and the second hole section 112 are transitioned by a chamfer 113. The depths of the first hole section 111 and the second hole section 112 are roughly the same. Therefore, the upper half of the jack 11 is the first hole section 111, and the lower half of the jack 11 is the second hole section 112, but the present invention is not limited thereto. The arrangement of the first hole section 111 and the second hole section 112 makes it easier for the plug-in column 201 of the functional module 20 to be inserted into the jack 11.

As shown in Fig. 2 to Fig. 4, the first rib 12 includes a non-interference section 121 and an interference section 122 which are sequentially distributed along the direction from outside to inside of the plug hole 11. The distance between the non-interference section 122 and the center line of the plug hole 11 is greater than the distance between the interference section 122 and the center line of the plug hole 11, so that the non-interference section 121 and the plug-in column 201 are in a non-interference contact fit or a small clearance fit, while the interference section 122 and the plug-in column 201 are in an interference fit. The non-interference section 121 is roughly located in the first hole section 111, and the interference section 122 is located in the second hole section 112, but it is not limited thereto.

As a preferred structure, the first ribs 12 and the second ribs 13 are alternately distributed in the circumferential direction of the socket 11. The provision of the second ribs 13 can reduce the number of the first ribs 12, thereby avoiding the plug-in and unplugging of the plug-in column 201 due to the excessive number of the first ribs 12. In addition, the utility model can use the second ribs 13 to support the plug-in column 201 on the basis of reducing the number of the first ribs 12, thereby ensuring the balance and stability of the plug-in column 201 in the socket 11. Specifically, the number of the first ribs 12 and the second ribs 13 are two respectively, the two first ribs 12 are arranged opposite to each other, the two second ribs 13 are arranged opposite to each other, and the arrangement direction of the two first ribs 12 is perpendicular to the arrangement direction of the two second ribs 13. Therefore, the two first ribs 12 and the two second ribs 13 are distributed in four corners in the socket 11.

As shown in Figures 6 and 7, in addition to a plurality of plug-in posts 201 and the conductive spring clips 202 therein, the functional module 20 also includes a housing 203 and a circuit board 204 in the housing 203. The plug-in posts 201 are arranged at the bottom of the housing 203, and the upper end of the conductive spring clip 202 is electrically connected to the circuit board 204.

As shown in FIG8 , the module connection terminal 2 and the relay insertion clamp spring 3 and the load input terminal 4 provided in the socket body 1 are made by bending the same spring sheet multiple times, so that the load input terminal 4, the relay insertion clamp spring 3 and the module connection terminal 2 are an integrated structure. Specifically, a connecting arm 5 is integrally formed between the load input terminal 4 and the relay insertion clamp spring 3, and the module connection terminal 2 is integrally formed in the middle position of the connecting arm 5 and extends upward. The shape of the connecting arm 5 can be set according to actual needs, and the load input terminal 4 and the relay insertion clamp spring 3 are roughly located at both ends of the connecting arm 5, and the load input terminal 4 extends in the horizontal direction.

The socket body 1 of the utility model is also provided with a jumper connection terminal 6, which is formed by bending a spring sheet, so that the jumper connection terminal 6, the load input terminal 4, the relay insertion clamp spring 3 and the module connection terminal 2 are in an integrated structure. Specifically, the above-mentioned connecting arm 5 is integrally formed with an upwardly extending arm 7, the arm 7 is parallel to the module connection terminal 2, and is located on the side of the module connection terminal 2 away from the relay insertion clamp spring 31, and the jumper connection terminal 6 is integrally formed at the top of the arm 7. The jumper connection terminal 6 is in a horizontal U-shape, and the opening of the U-shape faces the extension direction of the load output terminal. The two sides of the U-shape are respectively provided with slots 61 for plugging the conductive column of the jumper, and the notch of the slot 61 is located on the end face of the side where it is located, and the width of the slot 61 increases from the outside to the inside.

In this embodiment, the module connection terminal 2 is narrow at the top and wide at the bottom, so that the module connection terminal 2 can be inserted upward into the insertion hole 11. Specifically, an inclined step is provided on both sides of the approximately lower middle portion of the module connection terminal 2 in the width direction, so that the width of the module connection terminal 2 above the inclined step is narrower, and the width of the portion above the inclined step and above the inclined step is larger.

In this embodiment, the surface of the load input terminal 4 for contacting with the wire is provided with one or more convex ribs 41 protruding from the surface, so that the load input terminal 4 can ensure reliable contact with the wire when connected to the wire. The multiple convex ribs 41 are arranged along the width direction of the load input terminal 4, and each convex rib 41 extends along the length direction of the load input terminal 4. Specifically, the number of convex ribs 41 is two, but not limited to this. The load input terminal 4 is formed by stamping to form the convex rib 41, but the molding method of the convex rib 41 is not limited to this.

The utility model discloses a vibration-resistant module connection structure, which uses a plurality of ribs (i.e., a plurality of first ribs 12 and a plurality of second ribs 13) to limit the plug-in column 201, so as to ensure that the plug-in column 201 is closely matched with the socket 11, and prevent the plug-in column 201 from loosening or even falling off when vibrating. In particular, only the interference section 122 of the lower half of the first rib 12 is interference-matched with the plug-in column 201, so that the upper half of the plug-in column 201 in the socket 11 has a certain amount of movement, and the lower half is squeezed and deformed by the interference section 201 of the first rib, so that the plug-in and pull-out of the plug-in column 201 are convenient, and the plug-in column 201 and the socket 11 can be adaptively matched to stabilize the fixing force value within a certain range. The non-interference section 122 of the upper half of the first rib 12 can guide the insertion of the plug-in column 201, and can also support the upper half of the plug-in column 201, so that the plug-in column 201 will not shake. The second ribs 13 are provided to reduce the number of the first ribs 12 to avoid the plug-in column 201 being too tight due to an excessive number of the first ribs 12, and the second ribs 13 can be used to support the plug-in column 201 to ensure the balance and stability of the plug-in column 201 in the socket 11 to avoid shaking.

The utility model makes the load input terminal 4, the relay insertion spring clip 3 and the module connection terminal 2 an integrated structure, so that the module connection terminal 2 does not need to be clamped with the wire electrically connected between the load input terminal 4 and the relay insertion spring clip 3, and the problem of poor contact caused by poor clamping will not occur, which is conducive to realizing the reliable connection between the functional module 201 and the relay socket 10. At the same time, it is unnecessary to use a wire to connect the load input terminal 4 and the relay insertion spring clip 3. On the one hand, the reliability of the connection between the two is ensured, and on the other hand, the process of connecting the wires between the two can be reduced, which is conducive to improving production efficiency and reducing production costs. Similarly, the jumper connection terminal 6 is an integrated structure with the load input terminal 4, the relay insertion spring clip 3 and the module connection terminal 2, which can ensure the reliable connection between the jumper connection terminal 6 and the load input terminal 4 and the relay insertion spring clip 3, and reduce the connection process, improve production efficiency and reduce production costs.
