Description

A leaf spring socket

technical field

The utility model relates to a leaf spring socket.

technical background

The connector is an important device for conducting electric current. In modern industry, especially in electrical appliances, connectors are widely used. As an important part of the connector, the metal terminal has high requirements for its manufacturing and processing, and strives to be economical and simple to control the cost. At present, metal terminals mostly use a combination of wire spring socket and pin. The wire spring socket includes a sleeve body, a sleeve cap and a plurality of wire spring wires, and the sleeve body has a jack. Insert multiple spring wires into the socket, and the part of the wire spring protruding from the socket is bent toward the outer wall of the sleeve, so that the wire spring wires hang on the port of the socket, and then put the cap on one end of the sleeve body, so that The part where the wire spring wire protrudes from the jack is located in the gap between the inner wall of the sleeve cap and the outer wall of the sleeve, and the sleeve cap and the sleeve body are fixed.

However, using the wire spring socket, because there are many wire spring wires, and the assembly of the wire spring wires is still inseparable from manual means, the assembly is time-consuming and inefficient, which virtually increases the manufacturing cost of the product.

In order to achieve the above purpose, the utility model provides a leaf spring socket, the socket includes a cap and a body, the body has a socket, the cap is fixedly connected to one end of the body, the cap There is a through hole communicating with the socket, wherein the leaf spring sleeve also includes a leaf spring, and the leaf spring includes a connecting sleeve and a plurality of connecting sleeves extending from one end of the connecting sleeve along the axial direction of the socket. The contact piece and the connecting sleeve are located in the socket, and the gap between the fixed connection between the sleeve cap and the sleeve body clamps one end of the contact piece.

In the leaf spring socket provided by the utility model, a plurality of contacts on the connecting sleeve are integrally formed with the connecting sleeve. Compared with the traditional wire spring socket, it is only necessary to put the connecting sleeve into the socket instead of step by step. Put the wire spring wire into the socket, thus reducing the assembly process and improving the assembly efficiency.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1 and Figure 2, the utility model provides a leaf spring socket, which includes a cap 2 and a body 1, the body 1 has a socket 11, the cap 2 and the body One end of 1 is fixedly connected, and the sleeve cap 2 has a through hole 22 communicating with the jack 11, wherein the leaf spring socket also includes a leaf spring, and the leaf spring includes a connecting sleeve 31 and a connection sleeve from the connecting sleeve. One end of 31 is a plurality of contact pieces 32 extending along the axial direction of the socket 11, the connecting sleeve 31 is located in the socket 11, and the gap between the fixed connection of the sleeve cap 2 and the sleeve body 1 connects the contact pieces 32 at one end.

The leaf spring can be metals known to those skilled in the art such as iron and copper.

Wherein, the connecting sleeve 31 is a ring whose outer diameter is smaller than that of the insertion hole 11 , and the contact pieces 32 are evenly distributed along the circumference of one end of the connecting sleeve 31 .

Preferably, the socket 11 and the connecting sleeve 31 are circular in cross section.

Preferably, the cross section of the sleeve body 1 and the sleeve cap 2 is circular

The contact piece 32 has at least one protrusion 320 toward the axis of the insertion hole 11 . By adopting this structure, when the contact pin matched with the leaf spring socket is inserted into the insertion hole 11, good contact between the contact piece 32 and the contact pin is ensured.

Preferably, the outer diameter of one end of the sleeve body 1 is smaller than the outer diameters of other positions of the sleeve body 1 . The inner diameter of the sleeve cap 2 is larger than the outer diameter of the end of the sleeve body 1, the sleeve cap 2 is set on the end of the sleeve body 1, and one end of the contact piece 32 is located between the inner wall of the sleeve cap 2 and the sleeve body 1 in the gap between the outer walls. The sleeve cap 2 is a barrel-shaped object matched with the sleeve body 1, the port of the jack 11 is located at the end of the sleeve body 1, and the inner diameter of the sleeve cap 2 is larger than the outer diameter of the sleeve body 1 at this end. One end of the contact piece 32 is bent toward the outer wall of the sleeve body 1 , and the bent portion is located in the gap between the inner wall of the sleeve cap 2 and the outer wall of the sleeve body 1 at the port of the insertion hole 11 .

The sleeve cap 2 has a flange 21 protruding toward the through hole 22, and the inner diameter of the flange 21 is not smaller than the outer diameter of the contact pin matched with the wire spring socket.

In this way, one end of the contact piece 32 is fixed in the gap formed by the sleeve cap 2 , the flange 21 and the sleeve body 1 .

The other end of the connecting sleeve 31 is spaced from the bottom of the socket 11 . When the pin is inserted into the socket 11, the contact piece 32 will be squeezed, and the contact piece 32 will extend along the axis of the socket 11, so that the other end of the connecting sleeve 31 moves to the bottom of the socket 11, and the connecting sleeve 31 and The bottom of the insertion hole 11 has a certain interval, which can provide a certain movement space for the connecting sleeve 31 when the pin is inserted into the insertion hole 11 , without constraining the extension of the contact piece 32 . When the contact pin is pulled out from the socket 11, due to the elasticity of the contact piece 32, it automatically returns to the state before the contact pin is inserted.

Preferably, the connecting sleeve 31 and the contact piece 32 of the leaf spring are integrally formed. As shown in Fig. 3 and Fig. 4, a strip-shaped base 10 and a plurality of strips 20 extending from one side of the base 10 are formed on the metal sheet, and the plurality of strips 20 are perpendicular to the side of the base 10 and along the The sides are evenly aligned so that a comb-like structure is formed. Preferably, the interval between two adjacent strips 20 is equal to the width of the strips 20, so that two comb-like structures can be formed on one metal sheet. The strip-shaped substrate 10 is rolled along the side to form a ring with the same cross-section as that of the insertion hole 11 , that is, the connection sleeve 31 is formed. At this time, a part of one end of the strip 20 is bent in a direction away from the axis of the connecting sleeve 31 to form a hook-like structure; .

The leaf spring with this structure is easy to manufacture, and since a plurality of contact pieces 32 and the connecting sleeve 31 are integrally formed, the required procedures for assembling into the socket 11 are reduced, and the insertion of the leaf spring is improved to a great extent. Set assembly efficiency.
