DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

The present disclosure will be described further hereinafter in detail with reference to the embodiments in combination with attached drawings. In the description, the same or similar reference numerals in different embodiments denote the same or similar components. The following description to the embodiments with reference to the attached drawings is intended to illustrate the general concept of the present invention, and is not intended to limit the present disclosure to the embodiment set forth herein.
Further, in the following detailed description, for the sake of easy understanding, a plurality of details have been set forth so as to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is obvious that one or more embodiments can be carried out without these details. In other situations, the well-known structures and devices are embodied by way of example so as to simplify the attached drawings.
According to a general technical concept of embodiments of the present disclosure, there is provided a receptacle connector, comprising a housing, having a slot extending in a length direction of the housing and configured to receive and connect an electronic module therein. One spring press finger is formed on each of a pair of side walls of the slot facing to each other in a width direction of the housing. A section of slope surface with a predetermined length is formed on an inner surface of each of the spring press fingers, and an angle between the slope flat surface and a plane defined by the length direction and the width direction of the housing is more than 0 degree and less than 90 degrees. When the electronic module is inserted into the slot, the slope flat surfaces of the spring press fingers are pressed against side edges of a top of the electronic module, so that a resultant force of a pressing force exerted on the electronic module is directed to a bottom of the slot in a height direction of the housing.
Fig.1 shows a schematic perspective view of a receptacle connector for receiving and connecting an electronic module 200 therein according to an exemplary embodiment of the present invention, wherein, the electronic module 200 has been inserted into the slot of the housing 100 of the receptacle connector.
As illustrated in Fig. 1, the receptacle connector comprises a housing 100, for instance, a plastic housing formed by injection molding.
In the illustrated embodiment, the housing 100 has a length direction Y, a width direction X perpendicular to the length direction, and a height direction Z perpendicular to the length direction Y and the width direction X. The housing 100 has a slot extending in the length direction Y thereof and configured to receive and connect an electronic module 200 therein.
Continued with Fig.1, one spring press finger 110 is formed on each of a pair of side walls of the slot facing to each other in the width direction X of the housing 100.
Fig.2 shows a structural schematic view of a pair of spring press fingers 110 of the receptacle connector of Fig.1.
As shown in Fig. 1 and Fig. 2, in an embodiment of the present invention, a section of slope flat surface 111 with a predetermined length is formed on an inner surface of each of the spring press fingers 110, and an angle α between the slope flat surface 111 and a plane defined by the length direction Y and the width direction X of the housing 100 is more than 0 degree and less than 90 degrees.
Fig.3 shows an exploded view of pressing forces 2*F applied by the pair of spring press fingers 110 of the receptacle connector of Fig.1 onto the electronic module 200.
As shown in Figs. 1, 2 and 3, when the electronic module 200 is inserted into the slot of the housing 100, the slope flat surfaces 111 of the spring press fingers 110 are pressed against side edges 211 of a top of the electronic module 200, so that a resultant force 2*F2 of two pressing forces 2*F exerted on the electronic module 200 by the two spring press fingers 110 directs to a bottom of the slot in the height direction Z of the housing 100.
In the illustrated embodiment, as shown clearly in Fig.3, the pressing force F exerted on the electronic module 200 by each of spring press fingers 110 is directed to a direction perpendicular to the slope flat surface 111. The pressing force F exerted on the electronic module 200 by each of spring press fingers 110 has a horizontal component F1 in the width direction of the housing 100 and a vertical component F2 in the height direction Z of the housing 100. Two horizontal components of the pressing forces 2*F exerted on the electronic module 200 by the two spring press fingers 110 are the same in magnitude but opposite from each other in direction, thus they counteract with each other. Therefore, the resultant force 2*F2 of the two pressing forces 2*F exerted on the electronic module 200 by two spring press fingers 110 is the sum of the two vertical components and is directed to a bottom of the slot in the height direction Z of the housing 100, so that a vertically downward retaining force is always exerted on the electronic module 200 and the electronic module 200 can be reliably clamped within the slot of the housing 100the electronic module 200 from loosening. In this way, it can be ensured that terminals (not shown) at the bottom of the electronic module 200 can reliably come into contact with corresponding electrical connection terminals 120 in the housing 100, so that the receptacle connector and the electronic module 200 can still work reliably even in the condition of vibration.
In an exemplary embodiment of the present invention, the angle α between the slope flat surface 111 and the plane defined by the length direction Y and the width direction X of the housing 100 is more than 30 degrees and less than 60 degrees.
In an further exemplary embodiment of the present invention, the angle α between the slope flat surface 111 and the plane defined by the length direction Y and the width direction X of the housing 100 is equal to 45 degrees.
It should be noted that the present invention is not limited to the embodiments set forth hereinbefore, the angle α between the slope flat surface 111 and the plane defined by the length direction Y and the width direction X of the housing 100 can be set to a random degree in the range of 0 degree to 90 degrees, such as, 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees or the like.
As shown in Fig. 3, an end of each of the spring press fingers 110 is formed with a hook-shaped projection 112 so as to prevent the inserted electronic module 200 from being separated from the receptacle connector.
In the illustrated embodiment, as shown in Fig. 1, the spring press fingers 110 are formed integrally with the housing 100, for instance, the spring press fingers 110 and the housing 100 can be integrally formed by injection molding.
In the illustrated embodiment, as shown in Fig.1, the pair of spring press fingers 110 are offset from each other by a predetermined distance in the length direction Y, that is, the pair of spring press fingers 110 are not aligned with each other in the width direction X. In this way, the electronic module 200 can be more reliably retained within the slot of the housing 100.
In an exemplary embodiment of the present invention, the electronic module 200 can be a relay, and the receptacle connector can be a relay receptacle. However, the present invention is not limited thereto, for example, the electronic module 200 may be a memory bank module, and the receptacle connector may be a corresponding memory bank receptacle connector.
Fig. 4 is a schematic view of the pair of spring press fingers 110 of the receptacle connector of Fig.1 adapted to press and retain electronic modules 200 with various sizes.
In the illustrated embodiment, as shown in Fig.4, a size W, in the width direction of the housing 100, of the electronic module 200 clamped by the pair of spring press fingers 110 can be a random size more than an illustrated first size W1 and less than an illustrated second size W2. Thus, the receptacle connector of the present invention may be adapted to press and retain electronic modules 200 with various sizes. Therefore, when an electronic module 200 with a different size is replaced, the receptacle connector is not necessary to be replaced, and the receptacle connector of the present invention thus has a better universality.
Fig.5 is a schematic view of a control circuit board for mounting the receptacle connector.
As shown in Figs. 1 and 5, the housing 100 is provided with electrical connection terminals 120, one end of each of which is electrically connected to a circuit board 300 and the other end is electrically connected to the terminal at the bottom of the inserted electronic module 200. In this way, the electronic module 200 can be electrically connected to the circuit board 300. In an embodiment of the present invention, the electrical connection terminals 120 can be directly inserted into and connected to the circuit board 300.
As shown in Fig. 5, the housing 100 of the receptacle connector is vertically provided on the circuit board 300, and a plurality of receptacle connectors are arranged on the circuit board 300 so as to be separated from each other and be aligned in a line.
