Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the description of the present disclosure, it is to be understood that the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings.

Take a connector formed by combining the connecting socket 10 shown in fig. 1 and the connecting head 20 shown in fig. 2 as an example. The elastic member 11 of the connector holder 10 is in contact with the conductive terminal 21 of the connector 20 only through one conductive contact, so that the contact and the conductive terminal form a series electrical connection, which not only has poor contact stability, but also improves contact resistance. In order to further improve the electric connection of the connecting seat and the connecting head, the following technical scheme is provided in the disclosure.

As shown in fig. 3 to 5, an embodiment of the present disclosure provides a connection socket, including:

an insulating base 130;

a plurality of elastic members 110 juxtaposed on the insulating base 130, the elastic members 110 being bent to form elastic slots 111, each elastic member 110 having at least two conductive contacts 114 on a side facing the slots 111; the slot 111 is used for inserting the conductive terminal 210 of the connector 200;

the different conductive contacts 114 are used for contacting the conductive terminals 210 in the connector 200 and forming parallel electrical connection with the conductive terminals 210.

In the embodiments of the present disclosure, "a plurality" means at least two, specifically, 3, 4, or 5. The conductive contact points refer to the contact parts of the elastic piece and the conductive terminal after the conductive terminal of the connector is inserted into the elastic slot, and the effective contact between the connecting seat and the connector can be ensured by the conductive contact points. After the conductive terminals are inserted into the slots, the conductive terminals can be simultaneously contacted with the plurality of conductive contacts to realize parallel electric connection. The parallel connection mode reduces the impedance of the conductive contact part of the connecting seat and the connecting head, and further reduces the heating phenomenon of the connector caused by large-current electrification.

Moreover, a plurality of conductive contacts on the elastic piece are contacted with the conductive terminals at the same time, even if the elastic piece and the conductive terminals are staggered due to accidental conditions such as collision, the effective contact of at least part of the conductive contacts and the conductive terminals can be effectively ensured, and the contact stability of the connecting seat and the connecting head is improved.

Different conductive contacts are connected in parallel with a conductive terminal, it being possible for a plurality of conductive contacts to be connected in parallel with a conductive terminal at the same time, for example: as shown in fig. 10, one conductive terminal 210 is inserted into the elastic slot 111, and each conductive terminal 210 can contact at least two conductive contacts 114 of the elastic member 110. Alternatively, the plurality of elastic members 110 are connected in parallel with different conductive terminals 210. For example, at least two conductive terminals 210 are connected to one slot 111, wherein each conductive terminal 210 in the slot 111 contacts at least two conductive contacts 114.

In practical application, the conductive contact may be a protruding portion of the elastic member protruding toward the conductive terminal, and the conductive terminal portion contacting the conductive contact is a planar region or a recessed region; alternatively, the conductive contact of the elastic member is a flat area or a recessed area, and the conductive terminal portion in contact with the conductive contact has a convex portion protruding toward the elastic member. The reliability and stability of the electrical connection can be effectively ensured by the contact of the convex part and the plane area or the concave area.

In the elastic member, at least the conductive contact is made of a conductive material. In some specific examples, the elastic member is made of a conductive material such as a metal member or an alloy member.

Without limitation, as shown in fig. 4, the insulating base 130 includes four elastic members 110, each elastic member 110 forms a slot 111, and each slot 111 is capable of receiving one conductive terminal 210 of the connector 200. It is understood that the number of the elastic members 110 on the insulating base 130 may also be 2, 6, 8, 10, etc.

The insulating base can be made of insulating materials such as plastics or wood.

In a specific example, the width of the opening of the slot is smaller than the width of the conductive terminal, the conductive terminal can be unfolded in the process of being inserted into the slot, the opening of the slot is enlarged by the elasticity of the elastic piece, the conductive terminal can enter the slot at the moment, and the connection between the conductive terminal and the slot can be reinforced by the elasticity of the elastic piece.

In other alternative embodiments, as shown in fig. 4 and 5, the first end of the elastic member 110 has a plurality of elastic arms 112 distributed at intervals, the plurality of elastic arms 112 form a one-piece structure at the second end of the elastic member 110, and each of the elastic arms 112 has the conductive contact 114 thereon; the slot 111 is located between the first end and the second end, wherein the second end is opposite the first end.

In the implementation of the present disclosure, after the conductive terminal is inserted into the slot formed by the elastic member, since the surface of the elastic member contacting the conductive terminal cannot be an absolute plane theoretically, the plurality of conductive contacts are difficult to contact and conduct with the conductive terminal effectively and simultaneously. Through forming a plurality of elastic arms on the elastic piece, the elasticity of the elastic arms is utilized to ensure that the conductive contact on each elastic arm is simultaneously contacted with the conductive terminal, and the contact stability of the conductive contact and the conductive terminal is further improved.

In practical application, as shown in fig. 5, the second end of the elastic element 110 may extend out of the insulating base, and be used as a solder leg 115 to be soldered to an external circuit board or other devices, so as to achieve the connection between the circuit on the circuit board and the elastic element.

In other optional embodiments, the connection socket further comprises:

and the first reinforcing piece is positioned in the region of the insulating base except for the region where the elastic piece is installed.

The insulating base has a supporting effect on the elastic element, and correspondingly, the elastic element with higher strength also has a certain reinforcing effect on the insulating base. The insulating base part which is not provided with the elastic part area has weaker strength, so that the first reinforcing part is required for reinforcing, the strength of the insulating base is improved, the connecting seat and the connecting head are subjected to embedding or separating operation for many times, the damage to the insulating base is reduced, and the service life of the insulating base is prolonged.

The first reinforcing part can be made of metal parts or alloy parts and other materials with better strength.

In other alternative embodiments, as shown in fig. 3 and 4, the insulating base 130 includes:

and a mounting groove 133 between the boss 132 and the frame 131, in which the elastic member 110 is positioned.

The mounting groove 133 is used to accommodate not only the elastic member 110 but also the connection head 200 into which the connection head 200 is inserted. As shown in fig. 4, the mounting groove 133 is shaped like a Chinese character 'hui', and the elastic member 110 is at least partially disposed in the mounting groove 133 and is disposed in two longitudinal directions of the mounting groove 133. The first reinforcing member 120 is at least partially positioned in the installation groove 133 and positioned in both short side directions of the installation groove 133.

In a specific example, as shown in fig. 4, 5 and 10, the second end of the elastic member 110 has a bent portion 113 formed to be upwardly arched, and the insertion groove 111 is located between the bent portion 113 and the first end. Further, the frame 131 has a through hole for the second end of the elastic element 110 to pass through, and is exposed outside the frame 131. Specifically, the elastic arms 112 of the first end of the elastic element 110 abut against the bosses 132, the bent portion 113 of the second end of the elastic element 110 abuts against the frame 131, and the portion of the second end of the elastic element 110 except the bent portion 113 can pass through the through hole and be exposed outside the frame 131 as the solder leg 115 connected to an external circuit board or the like.
