Description

Technical Field

[0001] The utility model relates to the technical field of connector glue filling and fixing, in particular to a fixing device for a connector after glue filling. Background Technique

[0002] An electrical connector mainly includes a housing and connection terminals arranged in the housing. To meet the electrical and mechanical requirements of the electrical connector, the connection terminals are usually arranged in the housing in a sealed manner. The glue filling and sealing method involves pouring a sealing glue (such as silicone or other types of liquid glue) into the glue filling area of the housing (usually the area between the connection terminals and the housing). The sealing glue cures and adheres to the connection terminals and the housing. This sealing method has a simple process and good sealing effect, so it is widely used in the industry.

[0003] When filling and sealing with glue, the connector needs to be fixed. The conventional fixing method is insertion fixing, but there is still an inclination of the wire harness, resulting in poor glue sealing due to the incorrect position of the wire. Therefore, a fixing device for a connector after glue filling is proposed to solve this problem. Content of the Utility Model

A spring clamping component and a wire harness limiting component are respectively arranged on the top of the base, and the spring clamping component is arranged at the front end of the wire harness limiting component.

[0008] Preferably, the spring clamping component includes a pull rod main body. One end of the pull rod main body is detachably installed with a pull rod head through a cross recessed head screw, and the other end of the pull rod main body is fixedly installed with a pull rod front plate. A pull rod rubber pad is detachably installed on the side surface of the pull rod front plate through a cross recessed head screw.

[0009] Preferably, a spring and a pull rod cover are sleeved on the outer side of the pull rod main body. The pull rod cover is fixedly installed on the base through a bolt. A limit block rubber pad and a limit block are respectively fixedly installed on the surface of the base through bolts, and the limit block rubber pad is located in front of the limit block.

[0010] Preferably, a groove in the shape of the Chinese character 'Jia' is formed on the surface of the base, and the pull rod main body and the spring are semi-concealedly embedded in the groove.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a fixing device for connectors after potting, which has the following advantages:

[0015] 1. This fixing device for connectors after potting involves clamping the pull rod head with one hand and pulling it outward. When the pull rod head is compressed, the gap between the pull rod rubber pad and the limiting block rubber pad increases. After reaching a certain distance, the connector to be fixed can be placed into this gap. Releasing the hand allows the spring to rebound partially, and the connector is then clamped by the pull rod rubber pad and the limiting block rubber pad under the spring force, thus achieving clamping and fixing. Compared with the existing technology, the fixing method has been changed from the original connector plug-in fixing to clamping fixing, which is not only more convenient and faster, but also reduces the cost of use.

[0016] 2. This fixing device for connectors after potting allows the wire to be placed between the spring-loaded pin on the side of the wire harness buckle and the head ring of the wire harness buckle. After the spring-loaded pin springs back, the subsequent wires exceeding the height of the fixing device rest against the wire harness buckle, thus fixing the wires from the potting point to the wire harness buckle. The wire harness buckle limits and fixes the wire routing near the potting point, keeping the wires vertical for potting and preventing incomplete sealing due to improper wire positioning. At the same time, the knurled screws on the top can be manually adjusted to adjust the front and back position of the sliding block, thereby adjusting the front and back position of the wire after fixing. The knurled screws on the side can be manually adjusted to adjust the rising height of the lifting block, thereby adjusting the height position of the wire after fixing. Attached Figure Description

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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 A fixing device for connectors after potting includes a base 1. A spring clamping assembly and a wire harness limiting assembly are respectively disposed on the top of the base 1. The spring clamping assembly is located at the front end of the wire harness limiting assembly. The spring clamping assembly is used to clamp and fix the connector, and the wire harness limiting assembly is used to fix the wire harness. The height can also be adjusted to accommodate different wire lengths.

[0023] Please see Figure 1-3 The spring clamping assembly includes a pull rod body 16. One end of the pull rod body 16 is detachably mounted with a pull rod head 5 via a cross-slot countersunk screw 13. The other end of the pull rod body 16 is fixedly mounted with a pull rod front plate 4. A pull rod rubber pad 3 is detachably mounted on the side of the pull rod front plate 4 via a cross-slot countersunk screw 13.

[0024] Please see Figure 1-3 A spring 15 and a pull rod cover 2 are fitted onto the outer side of the pull rod body 16. A U-shaped groove is formed on the surface of the base 1, and the pull rod body 16 and spring 15 are semi-concealed within the groove. The pull rod cover 2 is fixedly installed to the base 1 with bolts. A limit block rubber pad 9 and a limit block 10 are respectively fixedly installed on the surface of the base 1 with bolts. The limit block rubber pad 9 is located in front of the limit block 10. The pull rod rubber pad 3 and the limit block rubber pad 9 are in direct contact with the connector being fixed, preventing slippage and avoiding damage to the connector surface.

[0025] Please see Figure 1-3The wiring harness limiting assembly includes a hollow support block 6, which is detachably mounted on the surface of the base 1 via a cross-grooved pan head screw 14. A lifting block 7 is inserted inside the hollow support block 6. A sliding block 8 is detachably mounted on the top of the lifting block 7 via a knurled screw 12. A wiring harness buckle 11 is threaded to the front end of the sliding block 8. A spring-loaded pin is provided on the side of the wiring harness buckle 11. This technology is consistent with the principle of the key buckle in the prior art. The side of the lifting block 7 is detachably mounted to the hollow support block 6 via a knurled screw 12.

[0026] Working principle: In use, by clamping the pull rod head 5 with one hand and pulling it outward, the spring 15 is compressed, and the gap between the pull rod rubber pad 3 and the limiting block rubber pad 9 increases. After reaching a certain distance, the connector to be fixed can be placed into this gap. Releasing the hand allows the spring 15 to rebound partially, and the connector is then clamped by the pull rod rubber pad 3 and the limiting block rubber pad 9 under the force of the spring 15, thereby achieving clamping and fixing. Compared with the existing technology, the fixing method has been changed from the original connector plug-in fixing to clamping fixing, which is not only more convenient and faster, but also reduces the cost of use.

[0027] By prying open the spring-loaded pin on the side of the wire harness buckle 11, the wire is placed between the head ring of the wire harness buckle 11 and the spring-loaded pin. After the spring-loaded pin springs back, the subsequent wires that exceed the height of the fixing device rest on the wire harness buckle 11, thus fixing the wires from the glue-filling point to the wire harness buckle 11. The wire harness buckle 11 limits and fixes the wire routing near the glue-filling point, keeping the wires vertical for glue filling and preventing incomplete glue sealing due to incorrect wire positioning. At the same time, manually adjusting the knurled screw 12 at the top can adjust the front and back position of the sliding block, thereby adjusting the front and back position of the wire after fixing. Manually adjusting the knurled screw 12 on the side can adjust the rising height of the lifting block, thereby adjusting the height position of the wire after fixing.
