Detailed Description

The invention will be further described with reference to specific embodiments.

The first embodiment is as follows: as shown in fig. 1 to 9, a pump further comprises: a circuit carrier 200; and

a male plug 3 having a mounting housing 31 for engaging with a circuit carrier, and a male contact 32 for electrical connection with the circuit carrier;

also included is a connector assembly 100; the connector 100 is connected with the male plug 3 in a clamping mode, and then the circuit is communicated.

That is, in the present embodiment, a pump is provided that completes an electric circuit by way of a connector. In the prior art, a considerable part of the products are connected by directly welding the wires with the circuit carrier, so that the method is time-consuming and labor-consuming, has high requirements on workers and has unstable product quality.

However, in the pump of this embodiment, since the mounting housing 31 with the male plug 3 is engaged with the circuit carrier; while male contacts 32 are electrically connected to the circuit carrier. The process of mounting the lines is very simple and a stable connection of the male contacts 32 to the circuit carrier can be achieved at the same time as the snap-in.

Compared with the connection between the electric wire and the circuit carrier realized in the prior art in a welding mode, in the embodiment, the electric wire and the circuit carrier are connected in a clamping mode through the mounting shell 31 and the circuit carrier, so that the mounting is more convenient, meanwhile, the dependence on the technology of workers is reduced, the labor intensity and the working difficulty are reduced, the working environment of the workers is improved, the production efficiency is improved, and the electric wire and the circuit carrier are particularly suitable for mass production.

The connector described in this embodiment refers to an intermediate component that is respectively matched with the male plug 3 and an external circuit to realize connection. That is, the connector is connected to the male connector 3, and the female contact pieces in the connector are connected to the external circuit, so that a complete circuit connection can be realized. In addition, the whole process is simple, and the standardization is easily formed in the processing execution process, so that the improvement of the product quality is ensured.

In addition, the circuit carrier described in this embodiment does not refer to an integrated circuit board in particular, but should refer to a circuit broadly.

The following describes in detail the structure of a connector for completing a circuit, which includes:

the connector comprises a connector body, a connecting piece and a connecting piece, wherein the connector body is provided with a lead section 1 for leading the electric wire to enter and a plug section 2 for externally connecting a male plug 3; the plug section 2 and the lead section 1 are integrally formed and configured, and an installation window 4 is arranged between the plug section 2 and the lead section 1; in the present embodiment, in order to solve the problems in the background art, the plug section 2 and the lead section 1 are integrally configured and designed as an integrally formed design, so that the connection stability of the device can be solved. But at the same time such devices suffer from the problem of inconvenient mounting of the female contact 21 during the actual connection. In order to solve the above problem, a mounting window 4 is provided between the plug section 2 and the lead section 1, through which the female contact 21 is inserted and mounted in the plug section 2 when the female contact 21 is mounted. This makes it easier and faster to install the female contact 21 while ensuring the stability and structural strength of the entire connector.

Meanwhile, if a mounting window 4 is designed simply, the problem of sealing cannot be realized, and therefore, a protection part 5 is arranged on the outer side of the mounting window 4, is clamped with the socket body and covers the mounting window 4. Therefore, the sealing performance of the connector is improved, and particularly the liquid tightness of the connector is improved when the connector is applied to a water pump product.

As shown in fig. 1 and 2, an installation diagram between the connector, the male plug 3 and the circuit carrier is specifically disclosed, and two components of the connector and the male plug 3 are arranged between the circuit carrier and the external circuit, and the male plug 3 solves the connection with the circuit carrier in the aspects of both the machinery and the circuit; the connector is used for simultaneously solving the connection between the male plug 3 and the external circuit in the aspects of both the machinery and the circuit. In such a way a stable communication of the lines is achieved.

To further increase the extent of the connector application, the angle between the plug section 2 and the lead section 1 is less than 180 °. As shown in fig. 3, the plug section 2 and the lead section 1 are perpendicular to each other. Of course, other obtuse angles or acute angles can be formed between the plug section 2 and the lead section 1, the angle can be customized according to actual conditions, and the design of the corresponding mounting window 4 can also provide convenience for the customized design of the angle. The design corresponding to the position of the mounting window 4 is associated with the angle of the slot 22, thereby reducing the difficulty of mounting.

In order to further facilitate the addition of other fittings for improving the sealing performance of the connector, an outer shell 6 is also added, and the mounting window 4 is molded on the outer shell 6. The outer housing 6 is now the outermost layer of the overall connector, and the mounting window 4 is formed in the outer housing 6 to facilitate mounting of the female contact 21. Meanwhile, the inserting section 2 is at least partially positioned in the outer shell 6 and is integrally formed with the outer shell 6; that is, as shown in fig. 4, 5 and 6, in the present embodiment, the outer housing 6 covers the plug section 2, and retains the interface of the lower end with the male plug 3. In practice, this can further increase the working strength of the integrity of the entire connector.

As shown in fig. 4, while the design of the mounting window 4 is such that the mounting window 4 coincides with the slot 22 in at least a partially vertical direction. Particularly, in a state where the plug section 2 and the lead section 1 are perpendicular to each other, the insertion groove 22 is directly visible from the mounting window 4, so that the female contact 21 can be mounted more conveniently.

In order to further ensure the stability of the connection between the protection piece 5 and the outer shell 6, the peripheral side of the protection piece 5 extends downwards and is formed with a clamping sheet 51, and the end of the clamping sheet 51 is formed with a clamping groove 52; a clamping block 61 is formed on the outer side of the outer shell 6, and the clamping block 61 is matched with the clamping groove 52; the clamping mode can reduce the difficulty of assembly and improve the stability.

Meanwhile, the clamping sheet 51 is formed with a plane limiting part 53; the outer edge of the outer shell 6 is formed with a mounting surface 62, and the plane limiting part 53 abuts against the outer side surface of the mounting surface 62. Such a design can increase the tightness of the connection between the guard 5 and the outer housing 6, preventing detachment, further increasing the sealing performance.

In order to further improve the sealing performance, particularly the waterproof performance, a boss 63 is formed at the upper end of the outer shell 6, a sealing ring 7 is sleeved outside the boss 63, and the sealing ring 7 is sleeved in the protection part 5.

The projection 63 is designed first, rather than being a flat surface, which already reduces the possibility of liquid entering the interior of the outer housing 6 and even the plug section 2, thereby increasing the water resistance. At the same time, by placing the sealing ring 7 in the protection member 5, that is, the protection member 5 is designed to cover the sealing ring 7 entirely, the waterproof performance can be increased. Meanwhile, the protection piece 5 can be tightly pressed on the upper end face of the sealing ring 7 after being clamped with the outer shell 6, so that the protection piece 5 is tightly attached to the sealing ring 7 and the boss 63 is tightly attached to the sealing ring 7 by the aid of the compressed state of the sealing ring 7, and waterproof performance can be further improved.

In order to further improve the sealing performance, particularly the waterproof performance, a sealing gasket 8 is arranged on the inner side of the outer shell 6, and the inner side wall of the sealing gasket 8 is used for abutting against the outer side surface of the male plug 3 when the male plug 3 is clamped in; as shown in fig. 1 and 2, that is, in practical use of the connector, a male plug 3 is also connected to the plug section 2. Since the outer housing 6 partially encloses the plug section 2, the male plug 3 partially enters the outer housing 6 when the male plug 3 is mated with the plug section 2. The function of the sealing gasket 8 is to achieve a waterproof seal of the lower end of the outer housing 6 by abutting against the outer side of the male plug 3. Of course, the outer side of the sealing mat 8 must also abut against the inner side of the outer housing 6 in this case, so that the sealing effect is ensured.

A plurality of limiting protrusions 81 are formed on the outer side of the sealing gasket 8, a mounting hole 64 is formed on the outer side of the outer shell 6, and at least part of the limiting protrusions 81 enter the mounting hole 64. The design can further increase the stability of the sealing gasket 8, and the sealing effect is not influenced by the position deviation caused by the insertion of the male plug 3.

In order to further increase the waterproof sealing effect, one end of the lead segment 1 is recessed inwards and is formed with a wire inlet end 11, a sealing plug 9 is arranged in the wire inlet end 11, and the outer edge of the sealing plug 9 abuts against the inner side wall of the wire inlet end 11; a plurality of threading holes 91 are formed in the sealing plug 9.

By recessing the end of the lead segment 1 inwards and using this recess to place the sealing plug 9, the sealing plug 9 is here shaped and dimensioned to seal the inlet end 11. I.e. the outer edge of the sealing plug 9 abuts against the inner side wall of said line entry end 11 after mounting has been completed. Then, the diameter of the threading hole 91 on the sealing plug 9 is also designed to match the diameter of the electric wire.

In practical use, one end of the wire passes through the threading hole 91 and the end with the metal spring plate is connected to the male contact plate, so as to achieve the conduction of the circuit. The electric wire passes through the threading hole 91 on the sealing plug 9, so that the sealing performance in the use process can be ensured.

In addition, in the prior art, one port often requires a plurality of wires, for example, three wires in the present embodiment. In view of the current situation, in the prior art, three connection ports are usually respectively arranged, and then a sealing plug 9 is separately arranged in each connection port. A problem with this design is that the plug 9 is mounted in a hole-by-hole position which is repeated each time, which is complicated and cumbersome.

In the embodiment, the shape of the sealing plug 9 is designed according to the number of the holes, the corresponding number of wire passing holes are formed in the sealing plug 9 in advance, and then the plurality of wires can be passed through by placing the designed sealing plug 9 on the wire inlet end 11.

Further, in order to make the installation of the sealing plug 9 more stable, and especially reduce the influence on the displacement of the sealing plug 9 in the threading process, a limiting step 12 is formed in the wire inlet end 11, and the sealing plug 9 is embedded in the wire inlet end 11 and abuts against the limiting step 12; even in the threading process, the sealing plug 9 cannot be displaced due to friction between the threading hole 91 and the electric wire, so that the waterproof effect is not affected.

The lower end of the limit clamping piece 10 is abutted against the upper side of the sealing plug 9; the lead segment 1 is clamped with the limiting clamping piece 10. The design can be matched with the limiting step 12 to stably limit the sealing plug 9 on the inner side of the lead wire section 1, so that the sealing plug 9 cannot be separated from the lead wire inlet end 11 by pulling or pushing in the threading process, and the sealing effect is ensured.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
