Description

Technical Field

[0001] This utility model relates to the field of cable assembly technology, and in particular to an encoder cable assembly. Background Technology

[0002] An encoder is a device that encodes and converts signals (such as bit streams) or data into a signal form that can be used for communication, transmission, and storage. Cables are required to ensure the connection between the encoder and other devices when they exchange signals.

[0003] When existing encoders are connected to cables, a large amount of dust and water vapor in the air can enter through the gaps at the connection between the encoder and the cable, causing poor contact and unstable signal transmission due to dust or water vapor adhering to the connection. To solve the above problems, this application proposes an encoder cable assembly. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an encoder cable assembly. By setting a sealing head, the inner wall of the socket can be sealed to ensure the airtightness of the connection and isolate dust and moisture. By setting a limiting mechanism, the connection can be ensured to be firm, the two are firmly connected, not easy to separate, and the signal transmission effect is excellent.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An encoder cable assembly includes a straight plug housing. A connecting block is fixedly connected to one end of the straight plug housing. A sealing head is fixedly connected to one end of the connecting block. An end block is fixedly connected to one end of the sealing head. A cable is fixedly connected to one end of the end block. An encoder connector is provided at the end of the straight plug housing away from the connecting block. Multiple male plugs are fixedly connected to the straight plug housing. A protrusion is fixedly connected to the encoder connector. The protrusion has multiple female insertion holes that mate with the male plugs. The encoder connector has two limiting mechanisms. Each limiting mechanism includes a limiting block that passes through and slides through the encoder connector. A spring is fixedly connected to one end of the limiting block, and the other end of the spring is fixedly connected to the encoder connector.

[0007] Preferably, a limiting groove is provided between the straight plug housing and the sealing head, and outside the connecting block.

[0008] Preferably, the straight plug housing has a groove at one end near the encoder connector, and the encoder connector has a socket that matches the straight plug housing.

[0009] Preferably, the limiting block is T-shaped, and the end of the limiting block near the protrusion is bullet-shaped. The encoder connector has a sliding groove, and the limiting block is slidably connected to the inner wall of the sliding groove.

[0010] Preferably, the cable includes an outer protective sheath, a shielding mesh, and multiple signal lines, wherein the outer protective sheath is fitted over the outer wall of the shielding mesh, and the shielding mesh is fitted over the outer wall of the multiple signal lines.

[0011] Preferably, the end of the signal line is equipped with a European-style terminal.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By inserting the straight plug housing into the socket, the male plug is inserted into the corresponding protrusion during the insertion process. During this process, the straight plug housing contacts the end bullet head of the limiting block, causing the limiting block to retract into the encoder connector and the spring to compress. Under the action of the spring, the limiting block is inserted into the limiting groove, thus completing the insertion and fixing between the straight plug housing and the encoder connector.

[0014] 2. When the operator holds the straight plug housing and the encoder connector respectively, a large amount of force is required to separate them. One end of the straight plug housing contacts the bullet head of the limit block, causing the limit block to retract into the encoder connector and the spring to compress until the straight plug housing and the encoder connector are separated. The separation of the two requires a large amount of force to pull them apart, ensuring that the connection between the two is firm.

[0015] In summary, by setting a sealing head, the inner wall of the socket can be sealed, ensuring the airtightness of the connection and isolating dust and moisture; by setting a limiting mechanism, the insertion can be guaranteed to be firm, the connection between the two is stable and not easy to separate, and the signal transmission effect is excellent.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 An encoder cable assembly includes a straight plug housing 1, a connecting block 2 fixedly connected to one end of the straight plug housing 1, a sealing head 3 fixedly connected to one end of the connecting block 2, the sealing head 3 having an arc at one end near the straight plug housing 1, the sealing head 3 contacting the inner wall of the socket 7 to ensure sealing performance, a limiting groove being formed between the straight plug housing 1 and the sealing head 3 and outside the connecting block 2, the installation between the straight plug housing 1 and the encoder connector 6 is completed by inserting the limiting block 11 into the limiting groove.

[0023] One end of the sealing head 3 is fixedly connected to an end block 4, and one end of the end block 4 is fixedly connected to a cable 5. The cable 5 includes an outer protective sleeve 13, a shielding mesh 14, and multiple signal lines 15. The outer protective sleeve 13 is fitted on the outer wall of the shielding mesh 14, and the shielding mesh 14 is fitted on the outer wall of the multiple signal lines 15. European terminals 16 are installed at the ends of the signal lines 15.

[0024] An encoder connector 6 is provided at the end of the straight plug housing 1 away from the connecting block 2. The encoder connector 6 is an encoder component. A groove is provided at the end of the straight plug housing 1 near the encoder connector 6. The encoder connector 6 has a socket 7 that mates with the straight plug housing 1. Multiple male plugs 8 are fixedly connected to the straight plug housing 1. The cable 5 is electrically connected to the male plugs 8. A protrusion 9 is fixedly connected to the encoder connector 6. Multiple female sockets 10 that mate with the male plugs 8 are provided on the protrusion 9. The electrical connection is completed by inserting the multiple male plugs 8 into the female sockets 10.

[0025] The encoder connector 6 is provided with two limiting mechanisms. The limiting mechanism includes a limiting block 11 that passes through the encoder connector 6 and is slidably connected to it. The limiting block 11 is T-shaped, and the end of the limiting block 11 near the protrusion 9 is bullet-shaped. The encoder connector 6 is provided with a sliding groove. The limiting block 11 is slidably connected to the inner wall of the sliding groove. One end of the limiting block 11 is fixedly connected to a spring 12, and the other end of the spring 12 is fixedly connected to the encoder connector 6. When plugging in, the bullet-shaped end of the limiting block 11 contacts the straight plug housing 1, causing the limiting block 11 to move until the limiting block 11 is inserted into the limiting groove to complete the firm plugging. Separation requires a large pulling force to ensure a firm connection.

[0026] In this invention, when it is necessary to connect and fix the straight plug housing 1 to the encoder connector 6, the straight plug housing 1 is inserted into the socket 7. During the insertion process, the male plug 8 is inserted into the corresponding protrusion 9. During this process, the straight plug housing 1 contacts the end bullet of the limiting block 11, causing the limiting block 11 to retract into the encoder connector 6 and the spring 12 to compress. Finally, the limiting block 11 is inserted into the limiting groove formed between the straight plug housing 1 and the sealing head 3. Under the action of the spring 12, the limiting block 11 is inserted into the limiting groove, completing the straight plug housing connection. 1. The connection between the straight plug housing 1 and the encoder connector 6 is fixed. When it is necessary to separate the straight plug housing 1 from the encoder connector 6, the operator needs to use a large force to separate the straight plug housing 1 and the encoder connector 6. One end of the straight plug housing 1 contacts the bullet head of the limiting block 11, causing the limiting block 11 to retract into the encoder connector 6 and the spring 12 to compress until the straight plug housing 1 and the encoder connector 6 are separated. The separation of the two requires a large force to pull them apart to ensure that the connection between the two is firm.

[0027] This invention solves the problem in the prior art where a large amount of dust and water vapor in the air can enter through the gaps at the connection between the encoder and the cable, causing poor contact and unstable signal transmission due to the combination of a sealing head and a limiting mechanism.
