Description
Technical Field
The utility model relates to a rectangle electric connector encapsulating device especially relates to a rectangle electric connector sealing colloid combination formula casting device, belongs to encapsulating process equipment.
Background
The rectangular electric connector is a plug element for electric appliances and is widely used in the field of aviation. Typically consisting of a guide pin fixed to the end of the housing, a connector (pin or socket) fixed in the housing. The electrical connector not only needs to meet the performance requirements of general electrical appliances, but also more importantly, the electrical connector must ensure good contact and reliable sealing. In order to improve the insulation sealing property and prevent the welding point between the connector and the lead from loosening and falling off due to vibration, a sealing adhesive is generally poured between the connectors.
The integral mold has the defects of difficult demolding, difficult glue filling amount control and the like although the structure is simple, in addition, due to the limitation of installation space, the interval between a guide pin and a connector of a rectangular electric connector of some special models is very small (L =0.3 mm), the mold is very difficult to position, and the welding point is exposed because the glue is thin and is easy to tear during demolding.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model aims to provide a rectangular electric connector sealing colloid combined casting device with simple structure, convenient demoulding and easy control of colloid pouring amount.
In order to achieve the above purpose, the utility model adopts the following technical scheme: it comprises a rectangular mould frame; the rectangular mould frame is formed by connecting and fixing two half mould frames in a face-to-face involutive mode through two bolts, and each half mould frame is in a Pi-shaped structure formed by two side plates fixed on the baffle.
The top surface of one baffle is provided with an overflow port which is positioned between the two side plates.
Compared with the prior art, the utility model discloses owing to adopted above-mentioned technical scheme, consequently have following advantage:
1) the original integral casting mold frame is changed into a combined structure formed by two half mold frames, so that the demolding can be realized only by loosening bolts, and the operation is simple and convenient;
2) because the involution positions of the two half mould frames are not contacted (a gap of S =0.2 mm is formed between the two side plates), the colloid can flow into the gap to realize filling, so that the thickness of the colloid at the position is increased; the coating reliability of the colloid butt joint plug-in unit and the welding point is improved, and the defect that the colloid at the thin wall part is easy to tear off when the integral die is demoulded is thoroughly avoided;
3) because the overflow port is arranged on the top surface of the half mold frame, the glue filling amount can be controlled by observing the glue at the position.

fig. 7 is a cross-sectional view taken along line C-C of fig. 6.
In the figure: the device comprises a half mould frame 1, a baffle 1-1, a side plate 1-2, an overflow port 1-3, a bolt 2, a butterfly nut 3, a rectangular electric connector 4, a shell 4-1, a guide pin 4-2, a colloid 4-3, a connector 4-4, a lead 5, an inner mould frame 6, an outer mould frame 7 and a top part device 8.
Detailed Description
The invention will be further described with reference to the following drawings and specific examples:
as shown in FIG. 1, the rectangular electrical connector 4 is composed of a guide pin 4-2 fixed to the top surface of a housing 4-1, and a plurality of connectors 4-4 fixed in the housing 4-1. In order to improve the insulation sealing property and prevent the welding point between the connector 4-4 and the lead 5 from loosening and falling off due to vibration, a sealant is generally poured between the connectors 4-4 to form a gel 4-3.
As shown in fig. 2-5, the utility model is a rectangular frame structure formed by two half mould frames 1 which are connected and fixed by two bolts 2 in a face-to-face way, and the upper end and the lower end of the rectangular frame are both open structures. Each half mould frame 1 is a pi-shaped structure formed by two side plates 1-2 fixed on a baffle plate 1-1.
In order to control the glue filling amount conveniently, an overflow port 1-3 is formed in the top surface of one baffle plate 1-1 and is located between two side plates 1-2.
When in use, the butterfly nut 3 is appropriately unscrewed, the utility model is placed on the top surface of the shell 4-1 of the rectangular electric connector 4, the lead 5 penetrates out of the rectangular frame enclosed by the two half mould frames 1, and then the butterfly nut 3 is screwed; when the two side plates 1-2 are respectively attached to the inner sides of the guide pins 4-2, the positioning of the half mold frame 1 in the left-right direction and the front-back direction is realized, and at the moment, the guide pins 4-2 block and limit the joint of the two half mold frames 1, so that a gap of S =0.2 mm can be formed. And pouring sealant into the rectangular frame from the top, and releasing the butterfly nuts 3 after the sealant is solidified so as to separate the two half mold frames 1. In the glue pouring process, when the glue overflows from the overflow port 5, the pouring can be stopped.
As shown in fig. 6-7, the conventional potting device is composed of a rectangular outer mold frame 7 fitted to the outer surface of the housing 4-1, and a rectangular inner mold frame 6 disposed in the outer mold frame and between the two pilot pins 4-2. In order to avoid dislocation, the two outer walls of the inner mold frame 6 must be tightly attached to the two inner walls of the outer mold frame 7; therefore, after the molding is completed, the rectangular electrical connector 4 is usually ejected upwards from the outer mold frame 7 by the ejector 8, and then the inner mold frame 6 is pulled out from the colloid 4-3. According to the operation process, the traditional glue pouring device has the defects of troublesome operation, difficult demoulding, difficult control of glue pouring amount and the like.
